المؤشر الورمي CA153 عناصر مختارة في اللعاب وعلاقتها بصحة الفم والاسنان ضمن مجموعة من النساء العراقيات المصابات بسرطان الثدي Salivary Tumor Marker CA15 - 3 And Selected Elements In Relation To Oral Health Status Among A Group of Iraqi Breast Cancer Women

المستخلص: Background : Breast cancer is the commonest type of malignancy worldwide and in Iraq. It is a serious disease that affects the general health and cause systemic changes that affect the physical and chemical properties of saliva leading to adverse effects on oral health.Aims of the study : The aims of this study were to assess the oral health condition (including dental caries, oral cleanliness and periodontal health condition), to evaluate the changes in salivary flow rate and to assess the concentration of tumor marker CA15 - 3 and selected elements (calcium, phosphorus, zinc, copper, total proteins) in saliva and their relation to oral variables among breast cancer women in comparison to control group.Subjects, Materials and Methods : The total sample consisted of 60 women aged 35 - 45 years attending Al - Kadhemyia Teaching Hospital. Those comprised 30 women newly diagnosed with breast cancer before starting treatment and 30 women without clinical signs and symptoms of breast cancer as a control group.Diagnosis and recording o f dental caries was done by using DMFS indexaccording to the criteria of WHO (1987). Plaque index of Silness and Loe (1964) and calculus component of Ramfjod index for periodontal disease (1959) were applied to assess oral cleanliness. Periodontal disease was evaluated using the gingival index (Loe and Silness, 1963) and loss of attachment level (Ramfjord, 1959). Stimulated salivary samples were collected and salivary flow rate, salivary CA15 - 3, calcium, phosphorus, zinc, copper ions and total proteins were determined.Results : Results showed that caries experience (DMFS) was higher among the study group compared with the control group but the difference was statistically not significant. The mean values of plaque index, calculus index, gingival index and loss of attachment were higher among the study group than the control group with a highly significant difference (P<0.01).The salivary levels of CA15 - 3 in breast cancer patients were higher than that of the controls with a highly significant difference (P<0.01). All the correlations between salivary CA15 - 3 and dental caries and periodontal diseases were statistically not significant.The salivary flow rate was lower among the study group than control group with a highly significant difference (P <0.01). Higher concentrations of salivary phosphorus, copper and total proteins were recorded among study group compared to control with statistically highly significant differences concerning phosphorus and copper (P<0.01). On the other hand, salivary calcium and zinc were lower among study group compared to control group with statistically highly significant difference concerning zinc (P<0.01). All the correlations between the caries experience and salivary constituents in the study and control groups were weak and not significant except the correlation with total proteins in the control group which was significantly positive. Concerning the correlations of oral hygiene and periodontal disease with salivary constituents, the study showed that all the correlations were weak and not significant except the correlations between the total proteins with loss of attachment in study group and with dental plaque in control group which were significantly positive relations.Conclusions : This study showed that the breast cancer patients had poor oral hygiene and higher rates of periodontal diseases and dental caries, therefore special preventive programs need to be designed for this group of patients. Also the results of this study could support the concept that salivary oncentrations of CA15 - 3 might serve to be used in the detection of breast cancer and/or the po operative follow - up of patients under treatment for carcinoma of the breast

المستخلص: القناة الثاقبة تركيب تشريحي لھا موقعا ھاما في الفك العلوي الامامي، دراسة خصائص ھذه القناة وتقييم علاقتھا مع العظم الامامي للقناة ضروري خلال زرع القواطع المركزية العلوية. الاشعة المقطعية لھذه المنطقة يمكن ان توفر ميزات دقيقة عن حدود وموقع القناة الثاقبة | The incisive canal is an anatomical structure with an important location in the anterior maxilla, analyzing this canal characteristics and evaluated its relation to the bone anterior to the canal is necessary during dental implantation of maxillary central incisors. CT scan image for this region can provide accurate features about the border, position of incisive canal and status of buccal bone anterior to this canal.Aim of the study : To study for the effect of gender, age and tooth loss in area of maxillary central incisors teeth on the dimensions of the incisive canal and buccal bone anterior to the canal using spiral computed tomography.Subjects, Materials and Methods : The sample consisted of prospective study for 156 subjects of both gender. The sample were divided into two groups, 120 dentate group (60 male and 60 female) with age ranging from (20 - 70) and 36 edentate group(with missing both maxillary central incisor) (18 male and 18 female) with age ranging from (50 - 70), which was further divided into two group according to the duration of maxillary central incisorsteeth loss, long duration (5+) years which consists of 26 subjects and short duration (<5 years) which consists of 10 subjects. All subjects attended to Baquba Teaching General Hospital in Diyala for Computed Tomographic scan investigation for different Maxillofacial diagnostic purposes from November/2013 to April/2014.Using sagittal section of computed tomography scan, the following measurementswere done : A - The diameters of incisive canal were measured at crestal, middle and apical level and the total mean value of canal diameters was calculated. B - The length of incisive canal.C - The distance of buccal bone anterior to incisive canal at crestal, middle and apical level and the total mean value of buccal bone distances was calculated. D - The length of buccal bone anterior to incisive canal from the apical measurement of buccal bone to the alveolar crest. The measuring unit was in millimeter in all measurements.Result : Gender had moderately strong effect on the dimensions of incisive canal and buccal bone anterior to this canal, the mean values begin generally higher for male as compared to female for both control and cases group. Absence of maxillary central incisors decreased incisive canal length and buccal bone dimensions with mean values begin higher in control group than that in cases group, the effect of teeth loss on these selected measurements seem to be strong ;however, canal diameter remain unchanged with dental status and there was no effect of teeth loss on this parameter.There was a moderately strong to strong effect of the duration of maxillary central incisors teeth loss on canal length and buccal bone dimensions with mean values being significantly lower in long duration (5+) years than that in short duration (<5 years) while it had weak effect on incisive canal diameter for both gender. The results showed that there was no significant linear correlation between age and all selected measurements in male and female for both control and cases group. Conclusion : CT scan is a valuable tool to evaluate the anatomic variation at the examined area in the current study, gender and dental status are important factors that can affect incisive canal characteristics and amount of bone anterior to the canal. Clinicians should perform careful planning using CT scans before performing dental implant surgeries in premaxillary region.

قياس كثافة العظم السنخي في الفك العلوي في سن 13 - 15 سنة باستخدام المفراس الحلزوني Measurment of Maxillary Alveolar Bone Density At 13 - 15 Years Age Using Spiral Omputerized Tomography

المستخلص: Bone density is a major factor that affect mini implant primarily stability. No Iraqi studies had been evaluated bone density related to mini - implant placement for orthodontic anchorage at age 13 - 15 years.The present research aims to evaluate gender, side and site differences in the bone density at various orthodontic implant sites for the maxillary alveolar bone (cortical; buccal and palatal and cancellous).The sample of this study consisted of CT images for patients who were attending Al. Shaheed Ghazi Al - Hariri Hospital/the Computerized Tomography department from January 2014 until May 2014. Twenty nine individuals (16 males and 13 females) had subjected to clinical examination, then 64 - multislice computed tomography scan data were evaluated and bone density was measured in Hounsfield unit at 21 points (9 points for each side and 3 points between the right and left central incisors).The results obtained showed that there were no significant differences in bone density between males and females and between the left and right sides. There are no significant differences in bone density between the maxillary buccal cortical bone and the palatal cortical bone except at lateral incisor and canine point where the palatal side had higher bone density than buccal side. The mean bone density of the cancellous bone in the anterior part was higher than that in the posterior of the maxilla.These differences in bone density between and within regions of the maxilla must be considered when placing mini implants and may provide valuable information when selecting sites, size, angle and placement methods for mini implant in the dental arch.

حاله الاكتئاب وعلاقتها بحاله الفم والخصائص الفزيوكيميائيه لدى طلاب المدارس من فئه عمر 15 سنة في مدينة الصويره - حافظة واسط - جمهورية العراق Depression Status In Relation To Oral Health Condition And Salivary Physiochemical Characteristics Among 15 Years Old School Students In Al - Swera City - Wassit Governorate - Iraq

المستخلص: Background : Depression is a common mental disorder that presents with depressed mood, its affect oral health through its effect on salivary function. The aims of this study were to assess the relation of depression status on prevalence and severity of dental caries and gingival inflammation among students aged 15 years in relation to salivary physical (flow rate and viscosity) and chemical characteristics concentration of (total protein, zinc, copper, chromium and lithium).Materials and methods : The total sample involved 800 students (males and females) aged 15 years old that were selected randomly, the depression status was measured using Children Depression Inventory (CDI) index that divided the students with depression into four groups according to severity of depression (low or average grade, high average grade, elevated grade and very elevated grade). The diagnosis and recording of dental caries was made by using Decay, Missing, Filled surface index (DMFs), according to the criteria of Manji et al (1989), while gingival condition was evaluated by using the gingival index by L?e and Silness, (1964). Salivary samples were collected under standardized condition from 30 students with very elevated grade and 30 students with low average grade, and then analyzed for measuring salivary flow rate and viscosity, in addition to the estimation of salivary elements (total protein, zinc, copper, chromium and lithium).Results : The prevalence of depression was 100%. The DMFs was lower among students with high average grade than other grades of depression with nonsignificant difference. The severity of dental caries was higher among students with elevated grade concerning D1, D3 and in very elevated grade of depression concerning D2, D4 with highly significant among D4 (P = 0.01). The prevalence of gingivitis in present study was found to be 100%, mild gingivitis occurrence found higher among low or average grade than other grades, but moderate gingivitis was more among very elevated grade, while sever gingivitis was absent. Salivary analysis demonstrated that the salivary flow rate was non significantly higher among students with low or average grade of depression than very elevated, while the viscosity of saliva was not significantly higher among students with very elevated grade. The data analysis of salivary elements found that the total protein and copper was higher among students with very elevated grade while other elements show the opposite result with significant difference concerning copper and zinc among females in very elevated grade, while others with not significant.Conclusion : The results of the current research revealed that caries experience and gingival inflammation increase with depression that has an adverse effect on salivary physicochemical characteristics. There were changes in saliva variables between low or average grade and very elevated grade of depression.

تاثير متسلل التسوس ممزوج مع او بدون مواد لاصقة تقليدية على ختم المينا السليمة : دراسة مختبرية The Influence of Caries Infiltrant Combined With And Without Conventional Adhesives On Sealing of Sound Enamel (In Vitro Study)

المستخلص: The formation of white spot lesions around fixed orthodontic attachments is a common complication during and following fixed orthodontic treatment, which hinder the results of a successfully completed case.The aim of the study was to assess the effectiveness of the Caries Infiltrant (ICON®) on prevention of caries on the smooth enamel surface when applied alone or combined with conventional adhesives. To achieve this objective, seventy eight human premolar enamel discs were randomly assigned to six groups (n=13). The discs were etched and treated with resins of different monomer content forming the following groups : (1)Untreated etched samples served as the negative control, (2) ICON® (DMG), (3) Adper™ SB 2 (3M ESPE), (4) Heliobond (Ivoclar Vivadent), (5) ICON®+ Adper™ SB 2 and (6) ICON®+ Heliobond. Specimens were subjected to demineralization by immersion in hydrochloric acid (pH 2.6) for 18 days. Calcium dissolution into the acid was assessed by photometric test via spectrophotometer at 24 hour intervals.The results revealed that, there was a highly significant difference between the sealed groups and the unsealed (untreated) one (p?0.00) indicating that the unsealed specimens showed the highest amount of Ca ion loss among all other groups. Additionally, there was no significant difference between untreated specimens and the ICON® sealed ones. While, Heliobond decreased the Ca ion loss significantly compared to the untreated specimens and Adper™ SB 2 performed significantly better than both ICON® and Heliobond. Furthermore, the combination of ICON® with either Adper™ SB 2 or Heliobond served as the best protective measures and maintained the protective effect during the whole experiment period.Therefore, within the limitations of this in vitro study, it could be concluded that the use of low - viscosity Caries Infiltrant prior to application of the tested conventional adhesives increases their protective effect against demineralization.

المستخلص: The study was conducted to assess the distribution, prevalence, severity of malocclusion and orthodontic treatment need in Baghdad governorate in relation to gender and residency, and whether it has increased or not over 12 years by comparison with previous survey in Baghdad.A multi - stage stratified sampling technique was used in this investigation to make the sample a representative of target population. The sample consisted of 2700 (1349 males and 1351 females) intermediate school students aged 13 years representing 3% of the total target population.A questionnaire was used to determine the perception of occlusion and orthodontic treatment demand of the students and the assessment procedures for occlusal features by direct intraoral measurement using veriner and an instrument to measure the rotated and displaced teeth. In summary the followingresults were obtained : 1 - 7.7% of the sample had some type of orthodontic treatment or consultation.2 - 39.1% of the students answered that they have malaligned teeth, being significantly more in female than males.3 - of the students who stated that they have malaligned teeth, 26% reported that they had crowded teeth, 26.6% had spaced teeth, 22.4% had protruded teeth and 25.7% had rotated and displaced teeth.4 - Regarding the answers of the effect of mal - aligned teeth, 70.3% answered that it affects their appearance, 17.7% chewing, and 7.7% speech while 4.1% answered that mal - aligned teeth did not affect appearance, chewing or speech.5 - the most common reasons for not seeking orthodontic treatment that the student thought that treatment is fear of pain (48.8%) and not important or not possible (25.8%).6 - One or more missing teeth due to extraction or trauma were found in 4.9% of the sample, and the most common extracted teeth were the first molars (1.6% mandibular and 0.9% maxillary). One or more rotated teeth were found in 38.3% of the sample; one or more displacement teeth were found in 19.6% of the sample.7 - The maxillary anterior region showed the highest prevalence of 2mm or more spacing (15.2%) and the mandibular anterior region showed the highest prevalence of 2mm or more crowding (12.6%); a maxillary central diastema of 1mm or more was found in 18.1% of the sample with a mean of 0.306±0.015mm.8 - Angle’s class I occlusion was found in 78.29%of the sample, class II in 19.5% (17.2% division 1 and 2.3% division 2) and 2.3% had class malocclusion (1.6% postural and 0.7% true). The mean overjet of the sample was 3.31± 0.04 mm. The mean overbite was 2.99±0.03 mm,9 - Midline shift (?1mm) was found in 54.3% of the sample (28% to the right and 26.3% to the left side).Soft tissue impingement was found in 3.3% (3% palatally and 0.3% labially). Normal lip form was found in 86.6%, contracting lip form in 10.1% and lip trap in 3.3% of the sample.10 - The DAI scores registered in this study ranged between 13 and 65 with a mean of 23.234±0.12. 7.3% with treatment highly desirable, and 4.5% with treatment mandatory.Significant changes in the proportions of malocclusions as a whole in school children were found over the last decade; also increase the need for orthodontic treatment among adolescents in the Baghdad commune and low perception level of the Baghdadi children to their own occlusion and the demand on treatment was remarkably low. This data will be useful for public oral health service and emphasize the need for orthodontic treatment among adolescents in Baghdad and stressing on the role of oral health education to encourage the children to undergo orthodontic treatment.

تاثير اضافة فلوريد الصوديوم كمطهر على بعض خواص مادة طبعة الالجنيت Effect of Sodium Fluoride Addition As A Disinfectant On Some Properties of Alginate Impression Material

المستخلص: المقدمة : تلوث طبعات الاسنان مع اللعاب والدم من تجويف الفم يحصل مباشرة في عيادات الاسنان ومختبرات صناعة الاسنان يجعل من طبعات الاسنان الملوثة فقرات يصعب التعامل معها من وجهة نظر انتشار الاخماج. اشارت التقارير السابقة الى امكانية الطبعات الملوثة بتلويث ال | Introduction : Contamination of dental impressions with saliva and blood from the oral cavity occurs readily in dental clinics, direct interaction between dental clinics and dental laboratories makes contaminated dental impressions difficult items to deal with it from the cross contamination point of view. Previous reports indicated that contaminated impressions can cross infect gypsum casts that were poured against them, however immersing or spraying commonly used alginate impression material with disinfectant may adversely affect the accuracy of dies or casts obtained. Objective : The objective was to evaluate the effect of (0.25%,0.5%,1%, 2%, 3%, 4% ) of (NaF) addition on the self - disinfection of alginate impression material and its effect on setting time, tear strength, dimensional change and accuracy of alginate impression materials and to compare this with CHX containing alginate material related to the same properties mentioned above.Materials and methods : A total No. of 800 specimens were prepared in this study, they were divided into five main groups according to the type of the tests used (tear strength test, setting time test, dimensional change test, dimensional accuracy test, and bacteriological tests (Streptococcus mutans and Candida albicans).Six concentrations of NaF from (0.25% to 4%) and 0.1% CHX gluconate were mixed with alginate impression material and compare it with control alginate without disinfectant. Results : The self - disinfecting impression material containing NaF showed a total kill of microorganisms immediately after impressions were made.Tear energies for all experimental impression materials were greater than those of the control products. There were no statistically significant differences between the dimensional change tests and also reproduction of detail test, that contained (NaF) and one that did not. With regard to setting time of the impressions, statistically significant reduction were seen between the control and experimental groups of alginate impression materials. The experimental material that did not contain (NaF) had a considerably longer setting time than all of the other materials tested.Conclusion : the use of (NaF) and CHX disinfection when taking alginate dental impression is a good measure in reduction of contamination and cross infection and have a minute effect on dimensional stability and is recommended as step in protecting dentist and dental laboratories teams.

المستخلص: Molar - Incisor hypomineralisation (MIH) is one of the biggest challenges with great clinical interest for dental practice because MIH has a great impact on the oral health as consequently, on the quality of life of children. Currently, the etiology of MIH remains unclear and is thought to be acquired via multifactorial, systemic disturbances during amelogenesis. There is no previous study concerning school children aged 7 - 9 years in Al - Najaf govemorate in order to estimate the prevalence and severity of molar incisorhypomineralisation and the possible associated risk factors. Objective : To estimate the prevalence , severity and the possible associated etiological factors of molar - incisor hypomineralisation and also to study the correlation between body mass index and molar - incisor hypomineralisation.Patients and Methods : A cross sectional study was conducted at Al - Najaf Govemorate, data were collected during the period from January to the end of April 2014. study population included the primary school children aged, 7 - 9 years of both genders who attending the primary schools of Al - Najaf govemorate. Children having amelogenesis imperfecta, tetracycline staining or undergoing orthodontic treatment at the time of study, those with completely broken crowns of the first permanent molars, or those whose parent/guardians refusedto missed data or not get back the questionnaire were excluded from the study. Sample size was calculated according to the standard equation and a total of 600 children were enrolled. A structured self - administered validated arabic language questionnaire and an examination sheet was measured. Body weight and height were measured and the body mass index was calculated according to the standards. Dental material and supplies were used in examination, Prior to the clinical examination the participating children were given a toothbrush and fluoridated toothpaste to brush their teeth thoroughly under the supervision of the researcher. The demarcated hypomineralization was recorded according to the 10 point scoring system depended on the European academy of pediatric dentistry evaluation criteria. The severity was assessed according to the clinical evaluation of the examiner and the presence of opacities. Data of the studied group were entered and analysed by using the statistical package for social sciences (SPSS) version 21 and appropriate statistical tests were used to assess the differences and correlations between variables. Results : The response rate was 84. 7% and the highest was in the 9 - year - old children, the participants were 532 children, the prevalence of hypomineralisation defect was 22.9%. The prevalence of demarcated hypomineralisation was increased concomitantly with the age, and the 9 - yearold children were the more affected. The overall prevalence of molar - incisor hypomineralisation among boys was lower than girls; (17.3%) and 22.6%, respectively. Molar - incisor hypomineralisation was more frequent in normal body mass index children. The total number of teeth of the studied group was 1464. The number of affected teeth was 3 81 represented (26%) of the total number of teeth. The molar and incisors were most affected with White/creamy demarcated opacities with no posr eruptive enamel breakdown, (27.7% and 15.2%), respectively. The severely affected teeth were 33 teeth, represented 4.5% of the total number of teeth of the 122 children , severely affected molars were 25 (5.1 %) and the severely affected incisors were 8 (0.8%), (P=0.001), Obeseand overweight were more likely to have more severely affected teeth and the severity was also increased with the age of child. Conclusions and Suggestions : The prevalence of Molar Incisor Hypomineralisation among Iraqi schoolchildren of Al Najaf govemorate was 22.9%, it was more prevalent among girls, the 9 - year - old children , normal body weight children and urban residents. Molars were more affected with than incisors. It was more prevalent in maxillary than mandibular teeth. The severely affected teeth represented 4.5% of the total number of teeth of the 122 children. , molars were more severely affected than incisors. The more severely affected teeth reported inobese and underweight children. Further studies are suggested for further understanding of the etiological and risk factors of the disease.

تقييم تاثير التيجان المقاومة للفولاذ (تقنية الهول) على معالجة التسوس للطواحن اللبنية : دراسة رجعية Evaluation of The Influence of Preformed Metal Crown ((Hall Technique)) On The Managing of Carious Primary Molars A Retrospective Study

المستخلص: Background : When prevention of dental caries fails, and a child is exposed to the risk of pain and infection, the disease must be managed to reduce this risk. There is a growing evidence supporting more 'biological approaches' for managing dental cariesin primary teeth. The Hall Technique is one of the biological approaches for managing caries in primary molars which involves sealing caries beneath preformed metal crowns (stainless steel crowns). The crown is cemented over the tooth without theuse of local anesthesia, caries removal, or tooth preparation. The clinical steps for the Hall Technique are straightforward but, as with all dental care provision, appropriate treatment planning for the procedure requires skill. The Hall Technique offers anothermethod of managing early to moderately advanced, active carious lesions in primary molars, with good evidence of effectiveness and acceptability.Aims of the study : This study was conducted to assess the possible local factors that might happen along with using this novel technique regarding the possible adverse effect of the increased occlusal - vertical dimension and the condition of the surrounding tissues.Also to assess the correlation between the rate of the successful outcome with the caries extension towards the pulp.In addition to evaluate the cost - effectiveness of the Hall Technique in comparison with the conventional restorations. Finally to estimate whether this technique can be performed efficiently by both the specialized dentists and general practitioners in terms of putting the appropriate treatment plan based on the radiographic assessment.Material and methods : A retrospective research was conducted, standardized bitewing radiographs of 100 patients between 3 - 9 years old were evaluated for marginal bone changes. The distance between the cemento - enamel junctions and the alveolar bonecrest was measured. The dentine was evaluated as well regarding the existence of clear band of dentine and the extension of the caries towards the pulp of the tooth. - The cost effectiveness was conducted by creating a scenario of the possible outcomes for the treatment decision whether it was Hall preformed metal crown or traditional restoration. Incremental cost - effectiveness ratio was calculated to find the savingamount value. - A panel consisting of five general practitioners and three specialized dentists weas asked to evaluate twelve bitewings radiograph presented to them and give their opinion whether these radiographs are suitable for Hall Technique or not.Results : The result of this presented study showed that there is decreasing in the distance between the cemento - enamel junction and alveolar bone level at the Hall PMCs treatment side between the before and after insertion periods.it also showed thatthere's no different bone level changes between the Hall preformed metal crown treatment side and its contra - lateral side regardless of its condition (Hall preformed metal crowns, no Hall preformed metal crowns). - A high rate of successful treatment is highly associated with observing a clear band of dentine but it is not associated with the carious extinction toward the pulp as long as a clear band of dentine can be seen. - The Hall Technique is more cost - effective by making more cost saving and more gained teeth. The Hall Technique can be performed efficiently by both the general practitioners and the specialized dentist.Conclusion : according on the results of this research it can be settled that there are no adverse effects of using Hall preformed metal crowns regarding the increase of occlusalvertical dimension and the periodontal condition also the Hall Technique is more costeffective and can be performed by specialized dentists as well as the general practitioners.

تقييم تاثير وجود الكحول في الغسولات الفموية على تلاشي قوة السلاسل التقويمية المرنة المختلفة الاشكال : دراسة مختبرية Evaluation of The Effect of Alcohol Presence In Mouth Washes On Force Degradation of Different Configurations of Elastomeric Chains (An In Vitro Study)

المستخلص: Elastomeric chains are one of the most commonly used force delivery systems. They have the ability to exert an interrupted force, convenience of use, compatibility to oral environment and cost effectiveness despite of the inherited disadvantage which is force degradation.This in vitro study was designed to evaluate the effect of alcohol presence in mouthwashes on force degradation of different configurations of clear elastomeric chains from Ortho Technology company which are : closed, short and long under the effect of time at different intervals (Initial, 1day, 1, 2, 3 and 4 weeks) with exposure to different chemical solutions.A total of (540) elastomeric chains of three different types (long, short and closed) transparent in color, with an initial length (19mm) and about 50% extension (29mm) were used for the study. These elastomeric chains was divided into four groups and exposed to different chemical solutions (Distilled water, Listerine Original alcoholic mouthwash, Listerine Zero alcohol mouth wash, Ethanol 26.9%) twice daily for 60 seconds each according to manufacturer's instructions to measure the amount of force degradation in different time intervals. These elastomeric chains were incubated in covered glass containers at 37C? for the entire testing period.The results of the present study showed that the elastomeric chains were greatly affected by time, the majority of force loss occurred after the first 24hr. then followed by a less steep gradient for the rest of the working period.We can conclude that alcoholic mouth wash (Listerine Original) causes an increase in force degradation of all types of elastomeric chains while alcohol free mouth wash (Listerine Zero) causes less force degradation of all types of elastomeric chains, additionally closed configuration elastomeric chains has the least percentage of force degradation than other configurations of elastomeric chains.

تاثير التدخين الخفيف على المستويات اللعابية لانزيم الفوسفاتيز القلوي والاوستيوكالسين لدى مرضى التهاب اللثة المزمن Effects of Light Smoking On Salivary Levels of Alkaline Phosphatase And Osteocalcin In Chronic Periodontitis Patients

المستخلص: Background Chronic periodontitis is an inflammatory disease that affects the supporting tissues of the teeth and it is common among adults. Smoking is an important risk factor for periodontitis that induces alveolar bone loss. Alkaline phosphatase enzyme is involved in the destruction of the human periodontium. It is produced by many cells such as polymorphonuclear leukocytes, osteoblasts, macrophages and fibroblasts within the area of the periodontium and gingival crevice. Osteocalcin is one of the most abundant matrix proteins found in bones and the only matrix protein synthesized exclusively there. Small osteocalcin fragments are found in areas of bone remodeling and are actually degradation products of the bone matrix.Aims of the study 1. Investigate whether light smoker chronic periodontitis patients exhibit different salivary concentrations of Alkaline Phosphatase and Osteocalcin compared to the non - smoker counterpart and compare to light smoker and nonsmoker control groups and 2.Correlate the clinical periodontal parameters (plaque index, gingival index, bleeding on probing, probing pocket depth and clinical attachment level) to the biochemical findings in light smokers and non - smokers chronic periodontitis and control groups. 3. Estimation of the salivary PH and flow rate and correlate them with clinical periodontal and biochemical parameters. Materials and Methods Five ml of unstimulated whole saliva samples and fullmouth clinical periodontal recordings (plaque index, gingival index, bleeding on probing, probing pocket depth and clinical attachment level) were obtained from study groups (25 light smokers and 33 non - smokers subjects, both with chronic periodontitis) and control groups (8 light smokers and 13 non - smokers subjects, both with healthy periodontium). All subjects were systemically healthy males, with age range (30 - 50) years. Salivary Alkaline phosphatase and Osteocalcin levels were determined by Colorimetric and Enzyme - linked Immunosorbent Assay, respectively. Salivary PH and flow rate were also measured.Results Smoker chronic periodontitis patients revealed non - significant differences in clinical periodontal parameters with non - smoker counterparts (P > 0.05) in terms of plaque index, probing pocket depth, clinical attachment loss, salivary PH and flow rate, with slight increase in plaque index value in smoker chronic periodontitis group(1.42±0.46) than non - smoker chronic periodontitis group (1.38±0.50), while there was slight decrease in mean value of probing pocket depth (3.90±1.78), clinical attachment level (3.22±0.93) and PH (7.58±0.50) in smoker chronic periodontitis group than non - smoker chronic periodontitis group (4.27±1.98), (3.74±0.85), (7.73±0.33) respectively. Flow rate value was higher in smoker chronic periodontitis (4.80±2.69) than non - smoker chronic periodontitis group (4.67±2.09). While there were highly significant differences in terms of gingival index and bleeding on probing (P ? 0.01). Osteocalcin levels were lower in smoker chronic periodontitis group (0.13±0.20) than non - smoker chronic periodontitis group (1.09±2.26) with significant difference (0.05 ? P > 0.01). Highly significant, strong, positive correlations were found between Osteocalcin concentration with plaque index and PH in non - smoker control group. Correlation analysis between Osteocalcin concentration and flow rate in smoker chronic periodontitis group revealed a significant, moderate, positive correlation.Mean of Alkaline phosphatase level was lower in smoker chronic periodontitis (11.14±4.53) than non - smoker chronic periodontitis (11.45±4.17) with a nonsignificant difference, while there was a significant difference in Alkaline phosphatase concentrations between smoker and non - smoker control subgroups.Correlation analysis between ALP concentration and clinical periodontal parameters (plaque index, gingival index, bleeding on probing, probing pocket depth and clinical attachment level) in chronic periodontitis smoker group appear non - significant, weak,negative and related non - significantly, weakly, positively with PH and flow rate. Clinical attachment level and PH correlated non - significantly, weakly, negatively with Alkaline phosphatase concentration, while plaque index, gingival index, bleeding on probing, probing pocket depth and flow rate related non - significantly, weakly, positively with Alkaline phosphatase concentration in chronic periodontitis non - smoker group. There was a significant, moderate, negative correlation between salivary PH and bleeding on probing and significant, weak, negative correlation regarding probing pocket depth in smoker chronic periodontitis group.A significant, weak, positive correlation between salivary flow rate and clinical attachment level was found in non - smoker chronic periodontitis group.There were non - significant differences between smoker chronic periodontitis and smoker control groups in terms of salivary PH, flow rate, Osteocalcin and Alkaline phosphatase concentrations. There were non - significant differences between non - smoker chronic periodontitis and non - smoker control groups in terms of PH, flow rate, Osteocalcin and Alkaline phosphatase concentrations. There were non - significant, weak increase in Alkaline phosphatase concentration compared to the increase in Osteocalcin concentration in smoker and non - smoker chronic periodontitis and smoker control groups, while there was a nonsignificant, weak decrease in Alkaline phosphatase concentration with increase in Osteocalcin concentration in non - smoker control group. Conclusion Within the limits of this study, it may be suggested that suppression of salivary Osteocalcin levels by smoking and weak increase in Alkaline phosphatase in smokers groups, may explain the deleterious effects of smoking on periodontal healthstatus.

تاثير انابيب الكاربون النانوية متعددة الجدران على الصلادة والتوصيلية الحرارية لمينا الاسنان Effect of Multi - Wall Carbon Nano Tubes On The Microhardness And Thermal Conductivity of Dental Namel

المستخلص: The objectives of this study was to evaluate the effect of addition of Multi - Wall Carbon Nano ubes(MWCNTs) of different concentration (0.05 mg/mL - 1, 0.25 mg/mL - 1, 0.5 mg/mL - 1and 1 mg/mL - 1) with on either (dimethyl sulphoxide DMSO and distilled water DW) on tooth enamel. It is intended to evaluate enamel microhardness in (Kg.m - 2) and enamel thermal conductivity before and after the application of (MWCNTs).Ninety mandubular first premolar were prepared for this study. They were divided into two groups. The first group contains 54 sample to measure the microhardness of the enamel. To overcome the teeth curvature in microhardness measurement, the position of indenter were optimized to coincide linear buccal surface. The second group contains 36 sample to measure the thermal conductivity of the enamel were prepared by cutting enamel part in triangle form with a base of 7. 5 mm , height of 9. 5 mm and thickness of 2 mm according to the requirements of the Fourier’s law by abrasive disk.The results enamel microhardness showed that a significant increase in the enamel microhardness and enamel thermal conductivity for groups 0.05 mg/mL (group B) , 0.25 mg/mL (group C ) , 0.5 mg/mL (group D ) and 1 mg/mL (group E ) compared with control group (group A ) in DW media and DMSO media. The results showed a significant increase in the enamel microhardness and enamel thermal conductivity for polished samples compared with unpolished samples in DW media and DMSO media. DMSO media increases the enamel microhardness and enamel thermal conductivity more effectively than DW media. Scanning electron microscope showed a significant deposition of MWCNTs in the depth of the enamel exceeding the surface layer. The polished specimens had more deposited MWCNTs compared with non - polished specimens. However, the nano dimensions with conjunction with pre - chemical treatment enabled the MWCNTs to penetrate and settle down inside the enamel.The final conclusion highest mean value obtained was 1 mg/mL (group E ) in the enamel microhardness and enamel thermal conductivity suspension in DW media and DMSO media.

المستخلص: Background : Dental implants provide a unique treatment modality for the replacement of lost dentition. The clinical success of implants has been achieved not only because of the mechanical strength or cellent biocompatibility of the implant material but also owing to other characteristics such as surface properties.Aims of the study : The goal of this study was to consider the role of nanoscale topographic modification of commercial pure titanium dental implant using a thermal deposition and chemical etching methods for the purpose of improving osseointegration.Materials and methods : Commercial pure titanium rod was machined into 40 dental implants. Each implant was machined in diameter about 3mm, length of 8mm (5mm was threaded part and 3mm was flat part). Implants were prepared and divided into 4 groups according to the types of surface modification method used : 1st group (10 implant) machined surface i.e remained without nano surface modification (control),2nd group include (10 implant)etched with 15N H2SO4 and 30% H2O2,3rd group include (10 implant)were coated with nano CPTi powder by thermal evaporation deposition technique,4th group (10 implant)were chemically etched with H2SO4 and H2O2 method to obtain a nano feature then coated with nano powder of CPTi by thermal evaporation deposition technique.Nano surfaces were characterized by scanning electron microscope (SEM), Xray diffraction (XRD), atomic force microscope (AFM), thickness measurement and microscopical examination for the invitro experiments. For the invivo part of study, the tibia of 10 white New Zealand rabbits were chosen as implantation sites. The tibia of each rabbit received two screws. Biomechanical test was performed after two weeks healing periods. Implants from eight animals were tested for the torque required to remove the implantfrom the bone and the other two animals were prepared for histological examination.Results : For invitro results, scanning electron microscope showed that chemical etching of Ti substrate becomes highly porous and has surface consisting of nano_sized pits and the combination of chemical etching and thermal evaporation of nano Ti showed nano rod like structure. The results of removal torque means value after 2 weeks of implantation showed that, there was a gradual increase in the removal torque mean values in the studied groups as a follow (M±SD) : 12.625 N.cm ± 0.517 machined surface, 30.500 N.cm ± 4.071 chemically etched, 46.875 N.cm ± 5.938 nano CPTi coating by thermal evaporation method, 51.250 N.cm ± 5.175 combination method of chemical etching and nano CP Ti coating. In addition, the histological analysis showed improved quality of bone in response to the nano surface modified screws, especially the combination treated implants show a well developed mature bone characterized by a well developed bony threads and haversian canal. Conclusion : The biomechanical and biological properties of the bone - implant interface associated with the nano modified implants were improved comparing to the unmodified implants. All nano modified CP Ti seems to be well tolerated by the bone since no adverse tissue reaction was evident and they have better mechanical properties and excellent biocompatibility through the improved performance regarding the bone implant contact area than the untreated implants.

نقييم الالفا اميليز والكورتيزول في اللعاب كمؤشرين جيويين للتوتر النفسي وعلاقتها بامراض المفصل الصدغي بين عينة من طلاب كلية طب الاسنان Assessment of Alpha - Amylase And Cortisol As Salivary Psychological Stress Markers In Relation To Temporomandibular Disorders Among A Sample of Dental Students

المستخلص: Background : University dental students perceived a higher level of stress prior to each examation especially the final. Therefore, there is a need for a useful noninvasive biomarker for measuring acute stress in those students. Many studies considered salivary alpha - amylase as a stress biomarker that is most often used in conjunction with cortisol. Understanding of the exact association between these two salivary stress markers are poorly established. Using a Helkimo anamnestic and clinical dysfunction scoring index for temporomandibular disorders can give a better insight about the association between these markers and temporomandibular joint disorders.The aims of study : was to evaluate the levels of salivary alpha - amylase and salivary cortisol in stressed students with temporomandibular joint disorders and the differences between these markers in relation to temporomandibular joint disorders students. This might give a better understanding to the role of psychological stress as an etiological factors for developing temporomandibular joint problems.Subjects, materials and methods : A total eighty (60 study and 20 control) participants aged between 20 and 24 years, were recruited for this study. The participants were final year undergraduate Baghdad university dental students who were examined and gave saliva samples before their final academic examination. Those with temporomandibular joint disorders problems were exposed to psychological stress and included on the study. While, those who were taking corticosteroids or hormone supplementation including oral contraceptives, or having history of head injury, orthodontic treatment, occlusal disharmonies and muscle tenderness due to systemic diseases as fibromyalgia, or having more than 2 missing posterior teeth were excluded. Salivary assay kits (alpha - amylase and cortisol) were used to measure those variables and a Helkimo anamnestic and clinical dysfunction scoring for temporomandibular joint disorders were utilized in this study.Results : There is statistically a highly significant difference of the salivary cortisol and salivary alpha - amylase in the patient group( stress with temporomandibular joint disorders) and control group. The absence of correlation between these salivary markers was founded. Correlation analysis of salivary cortisol with Helkimo anamnestic and clinical dysfunction score shows positive association expressed by significant probability of error (p) value while for salivary alpha - amylase there is no association.Conclusion : This study demonstrates that salivary alpha amylase can be used as a stress biomarker in conjunction with cortisol to assess temporomandibular joint problems due to psychological stress in university students.

الظواهر الوجهية والفموية، عوامل الاكسدة ومضادات الاكسدة في مصل ولعاب مرضى فقر الدم البحر الابيض المتوسط نوع بيتا في مدينة كربلاء Oro - Facial Manifestations, Oxidative Stress And Antioxidants Markers In Serum And Saliva of Patients With Beta Thalassemia Major In Karbala City

المستخلص: Thalassemia is a hereditary anemia resulting from defects in hemoglobin production. Beta Thalassemia, which is caused by a decrease in the production of beta globin chains, affects multiple organs and is ssociated with considerable morbidity and mortality. Aims of the study : The aims of this study were to study the oro - facial manifestations in beta thalassemia major patients and evaluation of the oxidative stress status in serum and saliva represented by malondialdehyde as xidative stress indicator and also assessment of serum and saliva antioxidants which are ceruloplasmin and uric acid in beta thalassemic patients with and without periodontitis and compared that with the healthy individuals in addition to investigate the relation between the clinical findings and laboratory investigations.Methods : Eighty seven (87) subjects were consented and contributed in this study, twenty eight (28) thalassemic patients with periodontitis, thirty (30) thalassemic patients without periodontitis and twenty nine (29) healthy subjects that were age matched with the patients. Oral examination has been done for each subject. Serum and saliva sample have been taken from each subject for analysis, to study malondialdehyde as oxidative stress and antioxidants ceruloplasmin and uric acid.Results : Malocclusion was the most common prevalent oro - facial manifestations (60%), followed by rodent face (35%), brown pigmentation of oral mucosa (23%) and incompetent lip (8%). The mean serum and saliva malondialdehyde were significantly higher in thalassemic patients with periodontitis than that in thalassemic patients without periodontitis and healthy subjects (p<0.001), while the mean serum and saliva ceruloplasmin were significantly higher in control group than that in other study groups (p<0.001). The mean serum uric acid was significantly higher in thalassemic patients without periodontitis than that in thalassemic patients with periodontitis and healthy subjects (p<0.001) and the mean saliva uric acid was significantly higher in thalassemic patients without periodontitis (p<0.05) compaired with thalassemic patients with periodontitis and healthy subjects. The results of this study showed that there were no significant correlation between serum and saliva malondialdehyde in any of study groups, while there was a positive significant linear correlation between serum and saliva ceruloplasmin in thalassemic patients with periodontitis (p<0.05), a negative significant linear correlation in healthy subjects (p<0.05) , a positive significant linear correlation in thalassemic patients without periodontitis (p<0.001). The results showed that there was a positive significant linear correlation between serum and saliva uric acid in thalassemic patients with periodontitis (p<0.05), a positive significant correlation in thalassemic patients without periodontitis (p<0.001) and no significant correlation between serum and saliva in healthy subjects. On the other hand there were no significant correlation between serum and saliva (malondialdehyde, ceruloplasmin and uric acid) and clinical attachment loss (p>0.05), except a positive significant linear correlation between clinical attachment loss and salivamalondialdehyde (p<0.05) was found. Conclusions : Malocclusion was the most prevalent oro - facial manifestations of beta thalassemia major patients. Oxidative stress play a significant role in the pathogenesis of beta thalassemia ,which was the main cause of red blood cells destruction represented by significant elevation of serum and saliva malondialdehyde and significant reduction of ceruloplasmin. Also oxidative stress remain contributing factor in periodontal tissue destruction, which was appeared as a significant increased level of saliva malondialdehyde and decreased saliva ceruloplasmin in patients with periodontitis and there was a significant correlation between saliva malondialdehyde and clinical attachment loss

التقييم النسيجي والكيمائي النسيجي المناعي لتاثير الاستخدام على VEGF/ N - acetyl D - glucosamine الموضعي ل شفاء العظم : دراسة تجريبية على الجرذان Histological And Immunohistochemical Evaluation of The Effect of Local Exogenous Application of VEGF /N - Acetyl D - Glucosamine On Bone Healing : (Experimental Study In Rats)

المستخلص: Background : Bones are rigid organs that constitute part of the endoskeleton of vertebrates. They support and protect the various organs of the body, produce red and white blood cells and store minerals. Bone tissue has been shown to contain numerous cell - to - cell signaling peptides called growth factors. These growth factors are thought to have important regulating effects for bone remodeling and bone healing. Several growth factors are expressed during fracture repair. of these, vascular endothelial growth factor (VEGF), is of particular interest because of its ability to induce neovascularization (angiogenesis). The responses to exogenous VEGF observed that a slow - release formulation of VEGF, applied locally at the site of bone damage, may prove to be an effective therapy to promote human bone repair. N - acetyl glucosamine is a monosaccharide, which are the derivatives of carbohydrates, it helps the body in making several other chemical agents which are used in the formation of bones, muscles and cartilages.N - acetylglucosamine is very effective in providing support for the skeletal system of the humans, and may provide strength to the ligaments and joints, and the skin remains fresh and glowing. Aims of study1. To identify role of local exogenous application of vascular endothelial growth factor and application of N - acetyl - D glucose amine as a biomaterial in bone healing.2. To analyze the expression of Vascular endothelial growth factor, tissue non specific ALP and bone matrix protein (collagen - 1) by immunohistochemistry in created bone defect after application with different biomaterials in a rat model. Materials and MethodsIn this experimental study fifty four male Albino rats, weighting (300 - 400) gram, aged (6 - 8) months were used and maintained under control conditions of temperature, drinking and food consumption. The animals were subjected for a surgical operation of medial sides of both tibial bone ( right side was considered as experimental site ,while left be the control one). The animals were divided into following groups according to the applicable growth factors.A. Contol group the bone defect treated with 1?m of normal saline and its number represented the all number of the following experimental groups as the left side of each animal considered to be the control.B. Experimental group includes ? Group I contains (18) rats, the bone defect treated with 1?ml of Vascular endothelial growth factor. ? Group II contains (18) rats the bone defect treated with 1?ml of Nacetyl D - glucosamine.? Group III contains (18) rats, the bone defect treated with 1?m combination of (VEGF& N - acetyl D - glucosamine).Every single group composed of 18 rats that studied in three periods 3,7,10 days (6 rats for each period). Histologic and immunohistochemical evaluation for VEGF, alkaline phosphatase and collagen type 1 were carried for all animals.Results : A. For Histological findings An early apposition of osteoid tissue was detected in VEGF group. Osteoblast, osteocyte and osteoclast cells count were demonstrated to be with high mean value in VEGF group followed by N - acetyl Dglucosamine group in periods 3,7,10 days post operative of bone defect.Inflammatory phase as first step in bone healing was detected in all study groups at 3 day, and combination group records highest value in the mean of inflammatory cell count in comparisum to others. Finally thestudy demonstrated that exogenous VEGF/ N - acetyl D - glucosamine has a direct effect on osteoblastic activity.B. For Immunohistochemical findings The present result showed positive expression of VEGF by bone marrow stromal cells, adipocytes, mesenchymal stem cells, precursor endothelial cells, and bone cells include osteoblasts and active osteocytes in different periods in all groups but in different score. Therefore, our primarily data provide evidence that VEGF activity is essential for appropriate bone formation and mineralization in response to injury. At day 3, bone marrow stromal cells in combination group records highVEGF expression, VEGF group is the second. At 7 and 10 day VEGF group records a highest VEGF expression in comparisum to other groups. The data showed a high expression for ALP during the formative stages of bone in all groups except combination group shows the lowest count for positive cells that expressed ALP.the present results showed that at day 3, bone marrow stromal cells in VEGF and N - acetyl D - glucosamine group records high collagen type I expression. Conclusion : the study demonstrated that low application of VEGF / Nacetyl D - glucosamine could be an effective therapeutic for bone injuries, these data are promising for a possible future clinical usage.

Assessment of The Oral Findings, Salivary Oxidative Status And Iga Level Among Group of Workers Exposed To Petroleum Pollutants In Al - Daura Oil Refinery

المستخلص: Petroleum is perhaps the most important substance consumed in modern society. Petroleum is unique and s a complex mixture of thousands of compounds. Oil refinery workers are continuously exposed to numerous hazardous materials and working conditions that place them at continuous risk of injury and death.Petroleum contains the heavy metals as a natural constituent or as additives. The main threats to human health from heavy metals are associated with exposure to lead, cadmium, mercury and arsenic. Several carcinogenic metals such as arsenic, cobalt, chromium, lead, mercury, and nickel induce redox reactions in living systems. These metals induce the production of reactive oxygen species in both in vivo and in vitro systems. These radicals have rendered oxidative damage to deoxyribonucleic acid, proteins, and lipids. Secretory immunoglobulin A is the main immunoglobulin found in mucous secretions from the tear glands, salivary glands, mammary glands, the respiratory system, the genito - urinary tract, and the gastrointestinal tract.Aims of the study Assessment of the salivary levels of heavy metals among the workers of Al - Daura oil refinery, assessment of the oxidative status in the oral cavity of the workers by measurement of Malondialdehyde and Superoxide dismutase markers,assessment of the oral immunological activity by measurement of secretory immunoglobulin A level in saliva and Assessment of the oral findings among the workers.Subjects, Materials and Methods This study was done in Al - Daura oil refinery, samples consist of 60 workers involved in refining processes as study group subdivided into three subgroups which represent the different sections in the refinery and 20 subjects not involved in refining processes as control group. Oral examination and saliva collection was done to assess the oral findings and measure the level of heavy metals (lead and cadmium), oxidative status (Malondialdehyde and Superoxide dismutase) and secretory IgA.Results The mean of salivary lead and cadmium was higher in study group (6.34 ?g/dl and 0.56 ?g/l respectively) than that of control group (3.3?g/dl and 0.34 ?g/l respectively) with highly significant difference (p

مستخلصات الشاي تاثيرها الذاتي او الاضافي على حياة خلايا السرطان : دراسة داخل وخارج الانبوب Herbal Tea : Its Own Or Additive Effect On The Survival Of Cancer Cell Line : An In Vitro And Ex Vivo Study

المستخلص: اجريت هذه الدراسة في فرع الفارماكولوجي في كلية الطب في الجامعة المستنصرية بالتعاون مع مركز ابحاث السرطان والوراثة\الجامعةالمستنصرية خلال الفترة من شهر كانون الثاني - شهراب لسنة 2014. الدراسة اقرت من قبل مجلس كلية الطب. صممت هذه الدراسة لتوضيح فعالية نبات ا | This study was conducted in the Department of Pharmacology at College of Medicine with incorporation of the Iraqi Center for Cancer and Medical Genetic Research at Al - Mustansiriya University, Baghdad, Iraq during 2014. This study was designed to elucidate the anti - cancer effect of Camellia sinensis by using four types of tea (black, green, white and oolong). Two experimental cancer models applied in this study; cancer cell lines (In vitro) and mice - bearing tumor (ex vivo). Several methodological and extracted aqueous and organic solvents were used to extract the tea. Microwave assisted extraction using distilled water as a solvent is applied in this study as the yield of bioactive substances are higher than other methods and organic solvents. The antioxidant activity was evaluated through the quantification of total flavonoids, total polyphenolic compound (bioflavanoids), total flavonols, reducing power, and proanthocyanidines. The scavenging property against reactive nitrogen species also was studied. The result showed that the different tea types contain approximately the same quantity of phenolic compounds; the only significant difference was in the proanthocyanidins level, which is a class of flavanols, found in high quantity in green tea compared with other tea extracts. Moreover, a significant scavenging property of peroxynitrite radical observed with all tea extracts. The extracts of black, green and oolong tea prevented or halted nitric oxide generation whereas the white extract tea promoted its generation, that is, a nitric oxide donor. The in vitro cytotoxic activity of Camellia sinensis in form of black, green, white and oolong tea was evaluated against four different types of cell lines. These are the AMN3 mammary cell carcinoma, Rhabdomyosarcoma, HeLa cells and Rat embryo fibroblast cells). The results showed greater effect of green and black tea over white tea and oolong tea against mammary cell carcinoma while the results of rhabdomyosarcoma cell line, which is an aggressive cancer cell, revealed a significant inhibitory effect of the growth of these cells by white and oolong tea extracts. All four types show almost equal percent of growth inhibition on HeLa cell line with the white tea been the most significant. A significant inhibitory effect of all tea extracts against the growth of rat embryo fibroblast cells indicated that the cytotoxic effect of the Camellia sinensis extended to normal cells and not specific to cancer cell. In addition, the antitumor effect of tea extracts was investigated (ex vivo) on BALB - c mice bearing - tumor. The volume, shape and color of the tumor masses were examined, in addition to measurement of the tissue malondialdehyde level as a biomarker of the lipid peroxidation, total tumor protein measurement and a histopathological study were done. The white tea showed antitumor effect by attenuating all the biomarkers of tumorogenesis. Herbal tea extracts induced DNA damage in term of separation the double strands molecule of calf thymus double stands DNA and human genomic DNA which may partly explained anti - cancer effect. We concluded that white tea extract is a promising nutrient that ameliorates the histopathological changes in mice bearing mammary tumor via generation reactive oxygen species by the evidence of activation lipid peroxidation process. Camellia sinensis plant can induce non harmful effect on DNA

تاثير كل من عقار الروزوفاستاتين وعقار الاتورفاستاتين على مؤشرات نسب السكر المصاحبة للسمنة المحدثة في الفئران Effects Of Atorvastatin Versus Rosuvastatin On Glycaemic Indices In Diet Induced Obese Mice

المستخلص: Numerous interventional cardiovascular disease outcome studies have resulted in statins being an essential factor of cardiovascular primary and secondary prevention strategies.In recent years there was ahigh concern that statin use is associated with diabetes new onset which is strong, independent risk factor for cardiovascular (CV) and cerebrovascular outcomes ,several studies resulted in conflicting results regarding different statin types & dose effect on glycemic control. Atorvastatin which is the most widely used statin worldwide and rosuvastatin the most efficacious ;they have different structural characteristics that have been speculated to have influence on diabetes onset.Aim of the study : The present study aims at investigating the effect of different doses of atorvastatin and rosuvastatin on glycaemic indices and metabolic disorders on mice model of diet induced obesity. Materials and method : The animals were divided into two groups : one served as control that received normal regular chow & the other group received high fat diet for the whole 12 weeks of experiment.After eight weeks of HFD feeding ;group (2) farther subdivided into five groups(12 mice in each) ; the first group received HFD only ,the second group received single daily dose / po of 20mg /kg rosuvastatin ,the third group received single daily dose / po of 40mg /kg rosuvastatin ,the fourth group received single daily dose / po of 20mg /kg atorvastatin ,and the fifth group received single daily dose / po of 40mg /kg atorvastatin for the last four weeks of experiment.Body weight ,food intake, lipid profile ,glycaemic indices were taken at baseline ,before treatment and after treatment.At the end of experiment ,animals were sacrificed , plasma & tissue sample were collected for biochemical analysis and histological observations.Results : Results of the present study shows that high fat diet feeding resulted in obesity development and metabolic abnormality like; hyperglycemia ,hyperinsulinemia ,insulin resistance , dyslipidemia and moderate to severe hepatic steatohepetitis compared to control group. and treatment resulted in significant improvement in lipid profile ,reduction in food intake ,body weight ,also associated with improvement in insulin sensitivity , hepatic steatohepetitis and reduction in insulin secretion.twenty mg/kg dose of atorvastatin showed better influence on glycaemic indices and comparable influence on hepatic picture over fourty mg/kg does while twenty mg/kg dose of rosuvastatin resulted in deterioration of glycaemic indices and no apparent improvement in hepatic steatosis. Unlike group that received 40 mg /kg rosuvastatin which showed significant improvement in all related metabolic disorders. Conclusion : Feeding mice with high calories diet for 2 month result in induction of obesity and disturbance of metabolic parameters. Treatment with rosuvastatin or atorvastatin has good impact on bodyweight , metabolic derangements &hepatic steatosis in obese mice. Both drugs seems to improve lipid profile in dose dependent manner, however their effects on glycaemic indices has different attitude. It is seems that rosuvastatin, especially at high dose, has better impact on glycaemic indices than atorvastatin and this might attributed to the difference in their pharmacokinetic properties

التقييم الفسلجي للاعتلال العصبي الذاتي لمرضى داء السكري

المستخلص: (Diabetes Mellitus) D.M : - is the most common endocrine disease, characterized by abnormalities of glucose, protein and lipid metabolism. Diabetic neuropathy is one of the long term chronic complications, which contributes to increase the morbidity & mortality rate in diabetes. One of the earliest manifestations of diabetic autonomic neuropathy is denervation of the cardiovascular system, assessment of cardiovascular reflexes affords a satisfactory evaluation. Along duration time.A battery of bedside clinical tests was used to assess the autonomic function of the heart. This is the response of blood pressure to sustained handgrip and standing - up. The R - R interval change and Q - T interval change in the E, C G in response to standing - up, deep breathing and valsalva maneuver. Number of the patients was 40 diabetic subject and 22 age and sex matched healthy controls. Insulin dependent diabetes Mellitus (IDDM) was 25(62.50%) of cases, non insulin dependent Diabetes Mellitus (NIDDM) was 15(37.5%) of cases, autonomic neuropathy was detected in 23 patients (57.5%), Orthostatic hypertension in 19 cases (47.5 %), abnormal blood pressure response to sustained hand grip in 20 (50%), abnormal valsalva ratio in 10 (25%), abnormal heart rate response to deep breathing in 11 cases (27.2%).Among the 13 patients with cardiac diabetic autonomic neuropathy, had a Q - Tc interval of > 440 ms ( p < 0.05 ). Compared to the remaining 4 patients had normal Q - Tc interval of 399.5 ± 37.49ms.Cardiovascular tests for cardiac autonomic neuropathy showed increase prevalence with increase in the duration of Diabetes Mellitus above 15 years.This study showed that diabetics had significantly impaired cardio - autonomic reflexes compared to non diabetics. Also, other group of diabetics who have apparently normal cardio - autonomic reflexes were found to have significantly different values compared to the control group, (heart rate variations with deep breathing and valsalva maneuver had a negative correlation with age)

تاثير استخدام عقار الميتفورمين منفردا او مع عقار السيتاكلبتين على مستويات الاومنتين - 1 لدى مرضى داء السكري من النوع الثاني Effects Of Metformin Alone Or In Combination With Sitagliptin On Serum Omentin - 1 Levels In Patients With Type - 2 Diabetes Mellitus

المستخلص: الخلفية : داء السكري يشير الى مجموعة من امراض الايض مع ارتفاع مستوى سكر الدم. يمثل النوع الثاني من داء السكري ما نسبته 90 - 95% من جميع حالات السكري. يمثل النقص في الانسولين ومقاومة الانسولين وغيرها من الاضطرابات الهرمونية المشاكل الاساسية لمرضى السكري من ال | Background : Diabetes mellitus (DM) describes chronic metabolic disorders with hyperglycemia. Type II DM (T2DM) represents for approximately 90 - 95% of all diabetic types. A combination of insulin deficiency, insulin resistance and other hormonal irregularities are key problems with T2DM. Adipose tissue can be classified into two types : the brown and white adipose tissues. The white type is considered an important secretory organ which produces many bioactive molecules, collectively termed adipokines. Recently, a new adipokine named omentin - 1, has been identified and it was found that individuals with impairment in glucose homeostasis and newly diagnosed T2DM showed a lower serum omentin - 1 level. However, the effects of antidiabetes drugs on serum omentin - 1 level had not been studied extensively.Objective : The current study was design to measure serum omentin - 1 in T2DM as comparing with control subjects, also to study the effect of three months therapy with metformin and/or sitagliptin (when added to ongoing metformin therapy) on serum omentin - 1 levels in addition to other parameters.Method : This study was carried out on thirty healthy control subjects, and sixty three T2DM patients. The patients enrolled in the current study were divided into two groups. First group : included thirty one of newly diagnosed T2DM patients, started treatment with metformin. Second group : included thirty two patients with T2DM, already on ongoing metformin therapy and started treatment with sitagliptin. All patients received their treatment for three months duration, and blood samples were collected from them at the beginning of the study and after three months of starting treatment to measure the possible change in the studied parameters which include : fasting blood glucose (FBG), postprandial blood glucose (PBG), Glycosylated haemoglobin (HbA1c), serum level of insulin, insulin resistance (IR), serum omentin - 1 levels, lipid profile, body mass index (BMI) as well as blood pressure. Results : The results showed that baseline level of serum omentin - 1 in the newly diagnosed T2DM was significantly lower than matched control subjects. The level of omentin - 1 was significantly reduced after three months duration of treatment in sitagliptin group with no significant change in metformin group. FBG, HbA1c and PBG were decreased significantly after three months in metformin group, while in sitagliptin group, only HbA1c and PBG were decreased significantly after three months. In both groups, and after three months duration of treatment, there were no significant changes in serum level of insulin, IR, TG, VLDL - C, HDL - C, BMI, and blood pressure.Conclusion : In newly diagnosed patients with T2DM, serum omentin - 1 was reduced compared to age and BMI matched healthy subjects. Three months treatment with sitagliptin resulted in a significant reduction in omentin - 1 levels compared with baseline values. However, three months treatment with metformin had no significant effect on serum omentin - 1 level compared with pre - treatment value

تاثير استخدام عقار الكلورال هيدريت منفردا او استعماله مجتمعا مع عقار الديازيبام كمهدئ عند قياس الاداء السمعي الدماغي عند الاطفال Chloral Hydrate Alone Or In Combination With Diazepam As A Sedative For Auditory Brainstem Response Testing In A Pediatric

المستخلص: اجريت الدراسة الحالية لبحث تاثير استخدام الكلورال هيدريت منفردا او استعماله مع الديازيبام كمهدئ عند قياس الاداء السمعي الدماغي عند الاطفال من اجل تقييم ما اذا كان اضافة الديازيبام له تاثير ايجابي او سلبي.اعتمدت الدراسة الحاليه على160 متطوعا من الاطفال ال | Background : children usually need sedation for diagnostic and therapeutic interventions. It is well known that pediatrics age groups are at higher risk for sedation - related complications than adults. Auditory brainstem response testing is one of the important diagnostic procedure that usually need sedation in order to preformed in children. Chloral hydrate is a hypnotic agent used since 1832 with low incidence of adverse events; whoever, despite the world wide use it is being abandoned due to bitter test, long time of sedation onset, vomiting and mild sedation. Rectally diazepam, on the other hand, produces higher and fast concentration in CSF with greater rate of success but probably with higher adverse events. Aim of the study : were to compare the sedative effect of chloral hydrate with chloral hydrate diazepam combination as well as their related adverse effects in children underwentg auditory brainstem response testing. Methods : in this randomized clinical study, 160 child underwent sedation for auditory brainstem response test participated. They were divided equally and randomly into 4 groups. Group A : Received 20 mg/Kg oral chloral hydrate as sedative, Group B : Received 20 mg/Kg oral chloral hydrate plus 0.5 mg/Kg diazepam rectally, Group C : Received 40 mg/Kg oral chloral hydrate as sedative, and Group D : Received 40 mg/Kg oral chloral hydrate plus 0.5 mg/Kg diazepam rectally. At the beginning, blood pressure, respiratory rates, peripheral oxygen saturation recorded, and then re - recorded immediately after drug administration and at (3, 5, 10, 20, …. min). Ramsay sedation scale used for assessment of the sedation level which measured every 10 min. Results : This study shown the beneficial use of chloral hydrate in combination with diazepam as sedation in ABR test (in groups D) by increased in the sedated number (p<0.05), decreased in the requirement of chloral hydrate re - dose, increased in the number of children whom completed ABR test (p<0.05) without significant differences on side effects or vital signs compared with the others three groups. 4.3. Conclusion : From this study we concluded that : • Used of oral chloral hydrate in dose (20mg/kg) alone not sufficient as sedative in paediatrics for ABR test.• Used of oral chloral hydrate dose (20mg/kg) in combination with rectal diazepam (0.5 mg/kg) better than used it alone as sedative in paediatrics for ABR test.• Used of oral chloral hydrate dose (40mg/kg) in combination with rectal diazepam (0.5 mg/kg) was the best sedative in paediatrics for ABR test. • Used of Chloral hydrate diazepam combination in ABR test of paediatrics increased the number of the sedated children, decreased the requirement of chloral hydrate re - dose, and increased the number of completed ABR test, with less complication

المستخلص: Doxorubicin is a member of anthracycline antibiotic that widely used in the treatment of different types of cancer such as hematological malignances, solid tumors, and different organ tumors, doxorubicin is very efficient in the treatment of cancer. But the use of doxorubicin is limited by the side effect of doxorubicin on the same organ, the most important organ that affected by doxorubicin is the heart, the toxicity of doxorubicin in the heart, the use of doxorubicin due to the cardiotoxicity that induced by doxorubicin will lead to cardiomyopathy and in the final result of these cardiotoxicity lead to congestive heart failure that occurred secondary to the cardiotoxicity may appear after long period of termination of treatment by doxorubicin.ObjectivesThe aim of the present study its investigate the possible modulation effect of drugs (verapamil, cyclosporine, labetalol) on the cardiotoxicity that induced by doxorubicin drug. Animals and methods forty Dwale - Spargue male rats where enrolled in this study, the animals divided into groups, (5) rats in each group and assigned as I,II,III,IV,V,VI,VII,VIII.Group I : received physiological saline (5ml/kg), orally, daily for ten days and served as the control.Group II : received a single dose of doxorubicin (15mg/kg), intraperitoneal and was sacrificed after 48 hours which served as doxorubicin group.Group III : received verapamil (5mg/kg), orally daily for ten days and on day eight, one hour after drug administration, a single dose of doxorubicin (15mg/kg), intraperitoneal were given.Group IV : received cyclosporine (0.5mg/kg), orally daily for ten days, and on day eight, one hour after drug administration, a single dose of doxorubicin (15mg/kg, intraperitoneal) was given.Group V : received cyclosporine (1mg/kg), orally daily for ten days ,and on day eight ,one hour after drug administration a single dose of doxorubicin (15mg/kg),intraperitoneal was given. Group VI : received both of verapamil (5mg/kg,orally) and cyclosporine (0.5mg/kg,orally) one hour apart, daily for ten days ,and on day eight, one hour after drug administration ,a single dose of doxorubicin (15mg/kg), intraperitoneal was given.Group VII : received labetalol (0.5mg/kg), orally daily for ten days, and on day eight, one hour after drug administration, a single dose of doxorubicin (15mg/kg, intraperitoneal) was given. Group VIII : received labetalol (1mg/kg, orally),daily for ten days ,and on day eight ,one hour after drug administration ,a single dose of doxorubicin (15mg/kg), intraperitoneal was given.Serum MDA, LDH, Troponin I, and interleukine - 17. Were measured and histopathological changes also viewed?ResultsThe results in this study showed an increase in the cardiac biomarkers in the doxorubicin group compared to the control group, the cardiac biomarkers that measured are LDH, MDA, Troponin I, interleukine - 17. Also the results showed histopathalogical changes in cardiac tissue in doxorubicin group as compared to the control group, also the results showed the pre - treatment with verapamil, cyclosporine low dose, cyclosporine high dose, combination of verapamil and cyclosporine low dose, labetalol low dose, labetalol high dose showed decreasing in the cardiac biomarkers MDA, LDH, Troponin I, interleukine - 17 to a significant amount compared to the doxorubicin group, also showed histopathlogical improvement in cardiac tissue. Conclusions Doxorubicin drug used as antineoplastic agent will produce a toxic effect on the cardiac tissue, this toxic effect will limit the use of doxorubicin, cyclosporine, labetalol and verapamil produced differential effects and protection from Doxorubicin induced cardio toxicity via amelioration of cardiac biomarkers and histopathological changes

المستخلص: اجريت الدراسة لتقييم مناعة المجتمع لكلا النازحين والمقيمين الملقحين بلقاح فيروس الحصبة ضد خمج الحصبة في محافظة بابل. لذا تضمنت هذه الدراسة معايرة الحالة المناعية في امصال النازحين والمقيمين محافظة بابل مع عزل وتشخيص فيروس الحصبة من الحالات المشتبه بها. ت | The study was conducted to evaluate the herd immunity for both the displaced and residents vaccinated with measles virus vaccine against measles infection in Babylon governorate. Therefore this study includes the evaluation of the immune status in sera of Babylon governorate displaced and residents with specific aspect for isolation and identification of measles virus from suspected cases. The immune response was evaluated by means of ELISA test (enzyme linked immunosorbet assay) for titration of IgM and IgG immunoglobulin level, in addition to evaluation of perforin level in the sera of 90 measles vaccinated individuals included in this study (50 displaced and 40 residents) from different areas in Babylon governorate, that were collected during the period extent from January up to April of 2016. Data about individuals were fixed according to information of formula including age, sex, geographical location, place displace of displaced and the vaccination date. Successful virus isolation from suspected cases on two types of cells culture included Vero cells line and chicken embryo fibroblast was carried. The titer of the isolated virus on Vero cell line reached (105.8 TCID50 / 0.1ml),which was higher than the titer of the virus isolated on CEF which reach (105.4 TCID50 / 0.1ml) after the third passage of the virus. The isolated virus was confirmed by indirect immunofluorescence technique.The age of subjects included in this study ranged from <1 year up to 24 years old. The results revealed that 15 (30%) have positive IgM index in sera of displaced, whereas residents sera sample shown only 6 (15%) positivity. Howover, all 90 (100%) subjects of both groups showed positive IgG index. The results of the present study showed that there were no significant difference of perforin level in sera of refugees and residents at p<0.05.Assaying of immune response against measles virus by measuring IgM immunoglobulin in sera of vaccinated displaced and resident with measles vaccine reflected a highly significant difference between two groups which reached 0.43 mIU/ml in sera of displaced in comparison with residents sera which reached 0.34 mIU/ml. The result showed also high significant differences in IgM between females and males. The females sera IgM levels of displaced and residents were higher than its level in males sera which reached 0.47 mIU/ml and 0.35 mIU/ml, respectively, in comparison with male sera level which reached 0.40 mIU/ml and 0.32 mIU/ml, respectively. According to age group, the highest IgM value was recorded in displaced and residents sera in age group 10 - 14years (0.50 mIU/ml) and 5 - 9years (0.36 mIU/ml) respec - tively. Whereas the lowest IgM serum value was detected in age group <1 year (0.34 mIU/ml) and 15 - 19years (0.31 mIU/ml) for displaced and residents subjects. According to geographical location, the highest IgM level was detected in sera of displaced from Tal Afar city (0.44 mIU/ml) followed by displaced from Ramadi (0.41 mIU/ml) and the lowest IgM value was detected in sera of displaced from Mosul city (0.33 mIU/ml). Whereas the highest IgM value in sera of residents in the subjects of Al - Mahaweel city (0.37 mIU/ml) followed by subjects of Hilla and Al - Qasem city (0.29 mIU/ml and 0.28 mIU/ml) respectively. For IgG serum immunoglobulin the results revealed that there was no difference in significant levels in both group population. But according to age groups significant difference between displaced and residents was detected at p <0.05 in which the 1 - 4 years old showed the highest IgG serum level in both group (1.98 mIU/ml and 2.18 mIU/ml) respectively. While the lowest IgG sera value was recorded in displaced age group of < 1 year old (0.60 mIU/ml) compared with residents age group of 20 - 24 years old (1.65 mIU/ml).It could be concluded that the results showed that the displaced do not have any effect on the residents of the province of Babylon for measles as a result of the good immunization by Babil Health directorate following to the Ministry of Health.

تاثير استخدام عقار الميتفورمين منفردا او استعماله مجتمعا مع عقار كلكلزايد على مستوى الاومنتين - 1 - في مرضى داء السكري من النوع الثاني Effects Of Metformin Alone Or In Combination With Gliclazide On Serum Omentin - 1 Levels In Patients With Type 2 Diabetes Mellitus

المستخلص: اجريت الدراسة الحالية لبحث التاثير العلاجي لاستخدام عقار الميتفورمين منفردا او استعماله مجتمعا مع عقار كلكلزايد على مستوى الاومنتين - 1 - باالاضافة الى المؤشرات الحيوية الاخرى في مرضى داء السكري من النوع الثاني من اجل تقييم ما اذا كان الجمع بين العقارين ( | Background : Omentin is a newly identified adipokine, which is highly expressed in visceral adipose tissue, in which omentin - 1 is the main isoform in human circulation, associated with cardio - metabolic disturbances. So considering the impact of anti - diabetic drug on omentin - 1 levels may provide adjuvant strategy to protect diabetic patients against clinical hazards.Aim of the study : The present study aimed to investigate the influence of treatment with metformin alone or in combination with gliclazide on the level of serum omentin - 1, in addition to the other biomarkers adopted in the study in order to evaluate whether the combined therapy (metformin plus gliclazide) ameliorate or adversely effects on some cardiac protector markers of metformin among recently diagnosed patients with type 2 diabetes mellitus.Methods : A total number of 100 recently diagnosed patients with type 2 diabetes mellitus were enrolled in the present study from December 2014 until June 2015. Sixty eight patients completed the 12 weeks course of treatment; divided into two equal groups based on treatment regimen in which group1 treated with metformin and group2 treated with metformin plus gliclazide. Thirty two patients did not complete the course of the treatment for unknown reasons and considered as default. In addition to 31 healthy volunteers were randomly chosen and considered as Control Group. In which all the participants in the study underwent detection of blood pressure, pulse rate, weight, height & BMI in addition to the estimation of the levels of others biochemical analysis as glycemic indices, lipid profile & serum omentin - 1at the beginning of the study & after 12 weeks of treatment regimen.Results : The results of this study shown the beneficial amelioration of metformin on some markers that affect CVS represented as significant reduction in BMI (p<0.05), modest improvement in lipid profile with modest elevation in HDL level & lowering blood pressure, significant reduction in the levels of blood glucose & HbA1C (p<0.05), improves insulin sensitivity, reduced insulin resistance, and elevation of serum omentin - 1 level among newly diagnosed type 2 diabetic patients (group1). Furthermore, the results of current study are revealed that adding of gliclazide to metformin in treatment of type 2 diabetic patients might influence the documented beneficial effects of metformin on cardiovascular system at least by adversely changing the levels of serum omentin - 1 among group 2. Conclusions : Adding of gliclazide to metformin in treatment of patients with type 2 DM might extend the therapeutic action of metformin in regarding much better controlling of glycemic indices, insulin sensitivity and lipid profile. But, at the same time, it might attenuate some of beneficial effects of metformin on cardiovascular system at least by adversely influence on body weight and serum omentin - 1 levels.

تاثير استخدام عقار النكلوزمايد بالمقارنة مع عقار المتفورمين على وزن الجسم ومؤشرات السكر في السمنة المحدثة عند الفئران Effects Of Use Of Niclosamide Drug In Comparison With Metformin Drug On Body Weight And Glycemic Indices In High Fat Diet Induced Obese Mice

المستخلص: في ستينيات القرن الماضي كان هناك نوع من العلاجات تستخدم للسيطرة على وزن الجسم او لتخفيفه , تلك المواد تعمل على تثبيط عضيات المايتوكوندريا من انتاج الطاقة وتحويل مجرى تفاعلات الاكسدة نحو انتاج الحرارة بدلا عن الطاقة وبذلك تحفز من زيادة اكسدة الشحوم ومادة ا | Background : Obesity is a state of excessive accumulation of fat tissue in the body , increasing energy expenditure is good way to manage obesity and the related complications. Mitochondrial uncouplers increase energy expenditure , they used before for weight controlling programs because these compounds uncouple mitochondria from generating ATP , moreover stimulate lipid and glucose oxidation preventing lipid accumulation in excess caloric intake conditions specially. Niclosamide an old drug introduced in 1960s as anthelmintic and had FDA approval for the treatment of most of tapeworm infections. It is well known mitochondrial uncoupler.Aim of the study : The present study aimed to investigate the influence of trial of the use of niclosamide in comparison to effect of metformin and their combination on body weight , glycemic indices and lipid profile in high fat diet induced obese mice.Materials and methods : The animals firstly divided to two groups one fed with normal regular mouse chow (30 mice) and the 2nd fed with high fat diet (60%kcal) for 2.5 months(100 mice) 10 mice from each group sacrificed at beginning of study represent baseline values and another 10 mice from each group sacrificed after 2.5 months to assess effect of high fat diet on study parameters. The group that fed with high fat diet further subdivided to 4 groups after 2.5 month of high fat diet feeding each 20 mice , 10 mice from each group sacrificed before treatment represent pretreatment values. Before treatment there are 5 groups assigned as group 1 fed normal regular mouse chow till the end of study , group 2 fed high fat diet without treatment till the end of study , group 3 fed with high fat diet till the end of study and treated with niclosamide for one month (150mg/kg) after obesity induction by high fat diet , group 4 fed with high fat diet till the end and treated by metformin (300mg/kg) for one month and finally group 5 fed with high fat diet till the end of study and treated by combination of niclosamide and metformin (150mg/kg , 300mg/kg respectively). blood samples taken from tail vein to evaluate the study parameters at baseline and after obesity induction by high fat diet (after 2.5 months) and after treatment ,then animals were sacrificed and livers were taken for histopathological observations.Results : The results of this study shown that the animals fed with high fat diet show metabolic disturbances manifested by significant increase (P < 0.05) in body weight , fasting insulin & fasting plasma glucose. Lipid profile show significant changes (P < 0.05)(cholesterol , triglycerides ,low density lipoproteins increased while high density lipoproteins decreased ) as compared to control group. High fat diet group also show impaired glucose tolerance , impaired insulin sensitivity and obvious liver structural changes manifested by sever steatosis.Treatment with niclosamide show improvement in all metabolic disturbances induced by obesity ; body Weight , fasting insulin and fasting plasma glucose reduced significantly (P < 0.05). Lipid profile parameters improved ; cholesterol , triglycerides , low density lipoproteins reduced significantly (P < 0.05) by one month treatment with niclosamide and high density lipoproteins increased significantly (P < 0.05) as compared to their baseline values before treatment, Glucose and insulin tolerance improved. It is nice to mention the influence of niclosamide in this study was comparable to metformin in all evaluated parameters.Combination of both drugs show favorable improvement in metabolic disturbances induced by obesity rather than each drug when used alone specially on liver histopathological changes.Combination of both drugs show significant reduction (P < 0.05) in body weight ,fasting plasma glucose and fasting plasma insulin. Lipid profile parameters improved significantly (P < 0.05) , glucose and insulin tolerance improved.Liver histopathological changes ameliorated to higher extent and become the closet to normal liver tissue morphology.Conclusions : The result suggest niclosamide have good antidiabetic action and can ameliorate the metabolic changes induced by obesity significantly. Its action is comparable to that of well known antidiabetic drug metformin. Niclosamide has favorable effect on body weight and can reduce body weight. Its combination with metformin show better improvement in metabolic disturbances induced by obesity and it has very good hepatoprotective effect against liver histopathological changes induced by high fat diet.

دراسة مستوى الهيبسيدين ومستقبلات الترانسفرين في عينات من المرضى العراقيين المصابين بحالات فقر دم نقص الحديد واضطرابات زيادة الحديد في الدم Study Of Hepcidin Level And Transferrin Level In Samples Of Iraqi Patients With Iron Overload And Iron Deficiency Disorders

المستخلص: The circulating peptide hepcidin is secreted mainly by the liver as an 84 - amino acid precursor that is subsequently processed and secreted as a 25 - amino acid peptide form. It is considered the "master regulator" of iron metabolism.Transferrin receptor is a carrier protein for transferrin. It is needed for the import of iron into the cell and is regulated in response to intracellular iron concentration. It imports iron by internalizing the transferrin - iron complex through receptor - mediated endocytosis. This study addresses the physiological role of hepcidin in vivo and investigates the role of hepcidin as an erythroid regulator, contributing to the modulation of iron absorption by the intestine and iron release by the macrophages in the situation of anemia with normal or increased iron stores. Measuring the transferrin receptor level and it's relation to hepcidin is another part of the data involved in this study.Methods : This study included 64 Iraqi patients, 34 of them have iron deficiency anemia and the other 30 are iron overload patients. They attended the National Center of Hematology and Thalassemia center in Al - Karama Teaching Hospital during the period from October 2014 until April 2015 together with 30 healthy controls. Information regarding age, sex and clinical presentation were recorded. ELISA technique used to measure hepcidin and transferrin receptors level in patients and healthy control groups.Results : ? Mean serum hepcidin level in iron deficiency anemia patients was (205.3ng/ml) while in iron overload patients was (6.7ng/ml).? Mean serum level of transferrin receptors in iron deficiency anemia was (11006.3ng/ml) and in iron overload was (604.5ng/ml).Conclusion : ? The mean level of serum hepcidin in thirty iron deficiency anemia patients is high. Its elevation represented an acute phase response. While in thirty patients with iron overload, hepcidin mean level was low mainly due to stress erythropoiesis.? The current study result addresses the usefulness of soluble transferrin receptor for assessing high iron status in population and how soluble transferrin receptor is useful in the evaluation of anemic patients.

تقييم نظام المعلومات الصحي في العراق Assessment Of The National Health Information System In Iraq

المستخلص: تعتبر الاحصائيات الصحية الرصينة ضرورة لاتخاذ القرارات السليمة في كل مستويات النظام الصحي. ولكن في الحقيقة ان نظم المعلومات الصحية في معظم البلدان تعتبر غير كافية لتوفير المعلومات اللا زمة لدعم الادارة الصحية ولهذا فان معظم النظم الحالية تعتبر كعائق اداري | Sound health statistics are essential for health decision - making at all levels of the health system. Unfortunately, health information systems in most countries are inadequate in providing the needed management support and the current systems are therefore widely seen as management obstacles rather than as tools, the current study is an attempt to assess the health information system in Iraq with recognizing the strengths, weaknesses and gaps in addition to assessment of the structure and performance of this system; it also attempts to assess the behavioral, technical and organizational determinants affecting the health information system performance. A cross - sectional study was conducted for the assessment process and the levels of the assessment included the ministry of health (national level), the health directorates (provincial level), the districts related to the health directorates reaching to the health centers level, as well as the hospitals related to the health directorates, in addition to the ministry of planning and the ministry of interior. In addition to ministry of health (central level) a total of six governorates were selected by simple random sampling including the capital Baghdad with a seven districts were selected from those governorates also by simple random sampling and a total of twenty six health centers were selected from those districts, as well a total of seven hospitals were included in the study from all governorate and they were selected according to convenience. The interview has been done by using the health metrics network assessment tool version 4, in addition to a complementary assessment tools which are the PRISM package tools that were used at the district and primary health center levels. Based on the data collected and according to the health metric network assessment tool findings the overall health information system has laid in the adequate state (65.96%) with most of its comprising components function poorly. Data dissemination and use and data management categories were the weakest with a score of 50% and 53.3% respectively, while for the resources category it was found to be adequate 63.3%, and for that of HIS indicators, data sources and information product categories they were 73.3%, 66% and 69.6% respectively. For that of the PRISM tools and the findings obtained by them from the collected data the results revealed that a low data quality in term of accuracy with 29.03% at the facility level and 55.35% at the district level, while the completeness rate was excellent with a score 96.38% at the facility level and 98.23% at the district level, for that of the timeliness it was 70.43% timeliness at the district level. The information use for a given feedback at the facility was 50% and at the district was 82.12% and for observed meeting records it was 50% for the facility and 41.6% for the district level. For that of the functionality a 34.61and 67.30% of the facilities reported having a reminder mechanism for data completeness process and meeting a deadline for submitting monthly reports respectively, Data analysis was better at the district 85.71% than at the facility 81.7%, Data display were present in all of the facilities and districts. For the technical determinant the results showed 57%, 85.7%, 71.4% and 100% of the district respondents felt that the form is complex and difficult to follow, data software is a user - friendly, information technology is easy to manage and a comprehensive picture of the health system performance is captured by the system respectively,85.7% believed that the information system collecting information from some vertical programs and one district reported of no collection at all, in addition to that 100% reported the absence of a software that integrates data from different information systems and the available information technology doesn&#39;t provide full access procedure to district and senior managers. Regarding the behavioral determinants the results revealed that overall mean confidence for the information system tasks is 69.41% while for that of the task competence the overall mean competence level is 37.1%. Knowledge of checking data quality, knowledge of health information system rationale and problem solving showed results of 35.32% 37.68% and 2.98% respectively, and that of motivation level was 43.4%. Organizational determinants results revealed that the management functions at facility and district levels were almost absent, while for the perceived promotion of a culture of information it showed a total score of 63.96% and rewarding for a good performance was 56.83%. The activities for promotion of a culture of information are a 25% at the facility level and 28.75% at the district level. And that of supervision quality at the facility were (72.80%). Availability of resources revealed that 100% of the facilities have two or more computers and calculators respectively while only 57.7% have an internet access. Access to the electricity and water supply is very high, No facility reported of running out in registers in the last 12 months. Finally, the current study shows the importance for the need of further attention to be drawn to HIS, in addition to that, increasing the awareness and well coordinated efforts that need to be done to overcome weaknesses and to provide a well functioning HIS enabling for evidence based decision making and action provision in the health system.

تقييم وحدات الرعاية المركزة لحديثي الولادة في ردهات الولادة لمستشفيات بغداد Evaluation Of Neonatal Intensive Care Units At Maternity Wards In Baghdad Hospitals

المستخلص: تتباين انظمة الرعاية لحديثي الولادة المطبقة ولكنها كلها تعتمد على وحدات الخدج الموجودة في مختلف بلدان العالم النامية والمتقدمة.انجزت هذه الدراسة المقطعية التقويمية في وحدات حديثي الولادة لردهات الولادة في مستشفيات بغداد (الكرخ والرصافة) مستثنين وحدات ال | Neonatal health care is provided via a variety of neonatal care units that are available globally both in different developing and developed countries.A cross - sectional evaluation study was conducted in all accessible fifteen neonatal intensive care units in Baghdad (Kharkh and Rosafa) maternity wards, excluding paediatric hospitals, during the period from November 2013 till the end of March 2014.The study aims : 1. Health care evaluation in neonatal intensive care units of maternity wards in Baghdad hospitals in terms of input (human and non - human resources) and outcome.2. Identifying causes of admissions and causes of deaths occurring in neonatal intensive care units The study consisted of two parts : A structure evaluation is using a check list to assess availability of human and non - human resources, covering infrastructure, manpower, equipment, and supplies; and an outcome evaluation study using hospital registration records review for causes of admission and causes of death in neonatal intensive care units during the year 2013.It was found that the mean number of specialist doctors in neonatal intensive care units was 2.1 and with standard deviation ±1.3, and college nurse was 2.2, with standard deviation of ±4.004, pharmacist was 0.4 with standard deviation of± 0.516 and for supplementary staff 1.5 with standard deviation of± 0.516.More than half 54% of nurses had no training in neonatal care.Concerning the availability of general equipment it was adequate except for computers 40%.Air conditioning, lighting and windows in addition to safe water supply was good 100% but ventilation was poor 67%, hand washing area was not always present 60% and free elbow operated water tubes were available in 6.7%. Availability of neonatal intensive care units special area was adequate for storage area 85.7% gowning area78.6%, while all the remaining areas were poorly available (resting room, examining room, mother room, boiling and autoclave room, area for mixing intravenous fluid and medication).Neonatal intensive care units were narrow and area/incubator ranging from 2.28m2 to 4.36m2/ incubator. Number of incubators was 246 with patient/ incubator ratio 53.6 : 1 and 27% of Neonatal intensive care units had no regular maintenance for incubators. Large Neonatal intensive care units >25 incubators were overcrowded, having below standards area/incubator, incubators covers only two third of neonatal care. Still up to one third of Neonatal intensive care units are getting their oxygen supply by cylinders, not pipes. Most equipment for individual use were poorly available. Most of Neonatal intensive care units emergency (cupboard) drugs and supplies were sufficiently available round the clock. Total admissions to Neonatal intensive care units were 13195 neonates. Male neonate's admissions 60% were higher than females 40%. Main causes of admission were Respiratory distress syndrome 43%, prematurity and low birth weight 19.4%, and Transient tachypnea 17.4%; birth asphyxia 4%, and hypoglycemia 3.8%, Congenital anomalies 3.7%, Neonatal jaundice 3%, while meconium aspiration and septicemia were the lowest1%. From all these admissions 74% were discharged well, (6%) were referred, while those discharged against medical advice were (4%) and the rest (16%) died. The main causes of death in Neonatal intensive care units were Respiratory distress syndrome 34%, prematurity and low birth weight 31% congenital anomalies 12%, birth asphyxia 8%, septicemia 4%, meconium aspiration 1% and 10% due to other unclassified causes. From this evaluation study, it can be concluded that there were Neonatal intensive care units with under staffing, undertraining and poor designing. Respiratory distress syndrome and prematurity were the main neonatal health problems.

تقييم استخدام الروزوفاستاتين والتلميسرتان في حالة تسمم عضلة القلب الحاد المحدث من استخدام الدوكسوروبيسيبن في الجرذان المختبرية Evaluation The Usage Of Rosuvastatin And Telmisartan In Doxorubicin Induced Acute Cardiotoxicity In Rats

المستخلص: اجريت الدراسة الحالية لتقييم التاثيرالعلاجي لاستخدام الروزوفاستاتين والتلمسارتان في التقليل من سمية القلب المحدثة من عقار الدوكسوروبسين في الجرذان المختبريةباستخدام الطرق الكيميائية الحيوية والنسيجية ومقارنة تاثير الاستخدام المزدوج بفعالية استخدام كل م | Background : Doxorubicin, an anthracycline antibiotic is a powerful antineoplastic drug, but its therapeutic usefulness is limited by its cardiotoxicity. Aim of the study : The present study investigated the influence of pretreatment with rosuvastatin and telmisartan alone or in combination in different doses on doxorubicin induced acute cardiotoxicity in rats using biochemical and histological approaches. Materials and methods : The animals were divided into eight groups of 5 animals each. The first group received no drug(s) po but a single dose of distilled water (7.5 ml/kg, ip) on day eight, which serves as the control group. The second group received no drug(s) po but a single dose of doxorubicin (15 mg/kg, ip) on day eight, and serves as doxorubicin only received group. The third and sixth group received rosuvastatin (2 , 10) mg/kg/day respectively for nine successive days, and on day eight, one hour after drug administration, a single dose of doxorubicin (15 mg/kg, ip) was given. The fourth and seventh group received telmisartan (2 , 4) mg/kg/day respectively for nine successive days, and on day eight, one hour after drug administration, a single dose of doxorubicin (15 mg/kg, ip) was given. The fifth and eighth group received both drugs, where the fifth group received both of rosuvastatin (2 mg/kg, po) and telmisartan (2 mg/kg, po), 1 hour apart, daily for nine successive days, and on day eight, one hour after drug administration, a single dose of doxorubicin (15 mg/kg, ip) was given. While the eighth group received both of rosuvastatin (10 mg/kg, po) and telmisartan (4 mg/kg, po), 1 hour apart, daily for nine successive days, and on day eight, one hour after drug administration, a single dose of doxorubicin (15 mg/kg, ip) was given.At day ten of the study, blood samples were taken for biochemical analysis, then animals were sacrificed and hearts were taken for histopathological observations. Results : Rats treated with doxorubicin showed cardiotoxicity as evidenced by significant elevation of serum cardiac troponin (CTn - I) level, lactate dehydrogenase (LDH) activity, serum malondialdehyde (MDA) level, and interluekine 17 (IL - 17) level associated with important histopathological alterations while pre - treatment with rosuvastatin and telmisartan elicited a significant decrease in the activities of all markers measured in comparison with doxorubicin treated group with pronounced resolution of Dox induced cardiac histological changes to a milder picture.Conclusion : These results suggest pretreatment with rosuvastatin and telmisartan alone or in combination provide a significant protective effect against acute - doxorubicin induced cardiotoxicity in rats represented by biochemical markers and histological approaches.

العلاقة بين تجارب الطفولة السيئة والمطاوعة على الصحة بعد البلوغ في بغداد The Relationship Of Adverse Childhood Experiences And Resilience To Adult's Health In Baghdad City

المستخلص: تجارب الطفولة السيئة تشير الى اكثر مصادر الاجهاد شيوعا وشدة التي يعاني منها الاطفال في حياتهم المبكرة. من هذه الخبرات الاساءة، الاهمال، العنف بين الابوين او مقدمي الرعاية والعنف المجتمعي. وتبين ان الاجهاد الطويل في الطفولة له اثار طيلة الحياة على صحة | Adverse Childhood Experiences refer to some of the most intensive and frequently occurring sources of stress that children may suffer early in life. Such experiences include multiple types of abuse; neglect; violence between parents or caregivers and community violence exposure. It has been shown that prolonged stress in childhood has life - long consequences for a person's health and well - being; it may lead to serious problems such as alcoholism, depression, eating disorders, heart diseases, cancer, and other chronic diseases. Resilience is the ability to manage crises, difficult situations and developmental tasks. Research on resilience has identified several factors that strengthen the power and resources of children as well as promote their abilities to cope successfully with crises and internal and external problems. This cross - sectional study was conducted to estimate the effect of adverse childhood experiences and resilient factors on adults’ heath. It was done during the period from January 2013 through January 2014. The study sample was drawn from Baghdad City. Multistage sampling technique was used to choose 13 primary health care centers and eight colleges from three universities in Baghdad; the questionnaire was filled through a direct interview with the participants. In addition to that, teachers of seven primary schools and two secondary schools were chosen by a convenient method. A total of 1040 subjects were surveyed and 1000 responded. Their age ranged between 18 to 59 years (32.08±11.169). Females constituted a higher proportion (58.3%) of the study sample, 60% of this sample had university/diploma as the highest level of education. The results showed (during childhood) that seeing or hearing a parent or household member in home being yelled at, screamed at, sworn at, insulted or humiliated was reported in 469 (46.9%). A parent, guardian or other household member yelled, screamed or swear at, insulted or humiliated them was registered in 387 (38.7%). A parent, guardian or other household member spanked, slapped, kicked, punched the subjects was seen in 335 (33.5%). father's death (when the subject's age was 15 years or less) was reported in 104 (10.4%) of the participants, and 74.8 % of the subjects like to be the kind of people their parents were. The multiple linear regression models demonstrated that being in the fourth quartile (highest quartile) of household dysfunction - abuse score is expected to significantly increase depression symptoms score by a mean of (10.4) compared to subjects in the lowest (first quartile) of household dysfunction - abuse score, being in the fourth quartile of family bonding score is expected to significantly decrease depression symptoms score by a mean of ( - 22.5) compared to subjects in the first quartile, the same is correct for self - esteem score which increases by a mean of (21.484) for the fourth quartile of family bonding score compared to subjects with lowest (first quartile) after adjusting other explanatory variables. Logistic regression model showed that being in a higher level of family bonding (fourth quartile) is expected to reduce the risk of having chronic physical diseases by almost the half (odds ratio =0.57) and being exposed to a high level of household dysfunction and abuse (fourth quartile) is expected to increase the risk of having chronic physical diseases by 81%. A positive history of suicidal attempts showed a strong positive association with mean score of household dysfunction and abuse. Family bonding during childhood appears to be the most important resilient factor that protects adults against sedative or narcotic usage, mental disorders, suicide attempts, and chronic physical diseases during adulthood. Higher levels of exposure to adverse childhood experiences have a positive association with substances usage, suicide attempts, symptoms of mental disorders and chronic physical diseases in adulthood.

المستخلص: هدف الدراسة : لتعيين العلاقة بين هرمون الهبيسيدين (hepcidin) (الهرمون المنظم لتوازن الحديد في الجسم والانترلوكين - 6 ( (interlukin - 6و علاقتها ببعض المتغيرات الكيميائية الحياتية عند المرضى المصابين بابيضاض الدم النيقاني الحاد ((AML قبل وبعد اكمال الجرعة الك | Acute myeloid leukemia (AML) is a clonal, malignant disease of hematopoietic tissues characterized by the accumulation of abnormal blast cells, especially in bone marrow, and impaired production of normal blood cells. The statistics show that this disease in men is more prevalent than women and this type of leukemia is increasing with age. Objectives : To assess biochemical changes related to iron status in acute myeloid leukemia pre and post course of chemotherapy and evaluate a relationship between serum hepcidin and IL - 6 in patients with acute myeloid leukemia pre and post chemotherapy and compare their levels to controls and their contribution on the pathogenesis of AML.Patients, Materials and Methods : The present study conducted at the National Center of Hematology and Baghdad Teaching Hospital in the Medical City from February 2014 to June 2014.The study included Fifty - eight (58) patients (30 male and 28 female) diagnosed with acute myeloid leukemia the age of patients range (15 - 65 years). Forty three (43)patients continued the study (24 male and 19 female) divided into two groups : Group (1) Patients with AML before starting chemotherapy. Group (2) the patients after 4 weeks of chemotherapy. Patient's treatment was done according to international protocol used in acute myeloid leukemia and called (3+7) where Doxorubicin was given from the first day to third day and Cyatrabine (Ara - C) was given from the first day to seventh day.Evaluationwas done on day (28) from starting chemotherapy to assess response of patients through bone marrow aspiration.All patients were subjected to complete history and physical examination. Diagnosis of AML patients was established by complete blood count and blood film, bone morrow aspiration and biopsy, hepcidin, interlukine - 6, C - reactive protein, ferritin, iron, total iron binding capacity, alkaline phosphstase, direct bilirubin were done for all patients.Forty - three (43) healthy subjects (24 male and 19 female) were enrolled in the study mainly from medical staff and their families. They were age and sex matched to patients group and considered as controls as ( Group 3).Results : • Serum hipcidin levels were significantly higher in(AML)patients (Group 2) compared to newly diagnosed(Group 1) and to healthy subjects ( P<0.0001).• Serum (IL - 6) levels were higher but not significant in(Group 1) compared to (Group 2) and significantly with healthy controls(P<0.214 and P<0.0001 respectively).• A significant increase in mean of serum ferritin levels were observed in (Group 2) compared to newly diagnosed patients (Group 1)(P<0.002) and the levels were significantly higher in newly diagnosed group compared to healthy controls (P<0.015).• Patients with (AML) during remission show significant decrease in levels of iron compared to newly diagnosed group(P<0.0001),while levels in healthy controls was higher values than both (Group 2) and (Group 1) (P<0.0001).• Total iron binding capacity (TIBC ) levels showed a significant decrease in (Group 2) after treatment compared to (Group 1) before treatment(P<0.0001) but the levels were significantly higher in healthy controls compared to (Group 1) and (Group 2) (P<0.0001).• Mean serum ALP levels showed highly increase in (Group 2) patients when compared to patients before treatment (Group 1)( P<0.0001), but the difference is not significantly higher between the newly diagnosis and controls (P<0.687).• A significant increase in mean serum direct bilirubin levels were observed in (Group 2) patients when compared to (Group 1) and healthy controls(P<0.0001).• Regarded to CRP levels in AML patients before and after treatment, the CRP levels increased in AML patients after treatment than newly diagnosed AML patients.Conclusions : Hepcidin and Interlukin - 6 may be used asprognostic for acute myeloid leukemia and also can play an important role in pathogenesis of AML.

دور هرمونات الاديبونكتيندور واللبتين والسايتوكينات لدى بعض المرضى المصابين بعجز القلب المزمن Role Of Adiponectin Leptin&Other Cytokines In Some Chronic Heart Failure Patients

المستخلص: عجز لقلب المزمن : حالة تقويضية معقدة متمثلة بمرحلة تشخيصية متقدمة مدمرة ونهائية. ان عملية انتقال المرض من مستقر الى دنف القلب(اعتلال عام مع هزال) ليست مفهومة جيدا, وهناك عدد من العمليات المختلفة للحفاظ من عملية الهدر، وهي في معظمها حيث وجدت لتكون في وقت م | Chronic Heart Failure(CHF)is a complex catabolic state that carries a devastating prognosis. The transmission from stable disease to cardiac cachexia is not well understood. A number of different mechanism maintain the wasting process, most of which were found to be activated early in the development of CHF.Many of these pathways are initially activated to protect heart from damage and to compensate for impaired myocardial function. Mediators that have been implicated in this process include pro - inflammatory cytokines like interleukin 1 and 6, tumour necrosis factor - ? and the acute phase protein (C.R - P)these cytokines are activated during the course of CHF and maintaining the wasting process. Little is known about the mechanism leading to cardiac cachexia (C.C).Adiponectin and leptin are a protein hormones derived from adipocytes and they are important regulator of energy metabolism and body weight. Previous studies of CHF and C.C , had great differences between cachectic and non - cachectic patients.OBJECTIVETo study the relationship between Adiponectin, leptin & cytokines in cachectic &non cachectic HF patients & compared the results with coronary artery disease( CAD) patients with preserved left ventricular systolic function( LVSF) &healthy control to elucidate their roles in pathobiochemistary of cachexia, & to study the prognostic power of adiponectin in CHF, also to identify & confirm the role of proinflammatory cytokine(IL - 6& TNF - ?)& systemic inflammation marker (C - R.P)in the progression of CHF to cardiac cachexia.SUBJECTS &METHODE Studies were performed in Cardiology Clinics in Ibn Al - Betar hospital for cardiac surgery. Eighty eight subjects were divided into four groups each contain 22 subjects are enrolled in this study : 1st group : patient with HF(reduce LVSF)with cachexia include 5 females &17 males with age range from 47 - 76 years;2nd group : patients with HF(reduce LVSF)but without cachexia include 6 females& 16 males with age range from 34 - 70 years;3rd group : patients with CAD (preserved LVSF)include 11 males &11 females with age range from35 - 80 years & 4th group : consisted of healthy controls include 11male s& 11 females with age range from 36 - 65 years. The hormonal assay was done by ELISA.RESULTSPatients with CHF with cachexia had significantly higher concentrations of adiponectin than all other groups(p=0.004) ,that are associated with significant decrease in serum level of leptin(p=0.002), significant increase in serum level of IL - 6 when compared to other groups (p=0.0001)& significant increase in number of C - R.P positive compared only to healthy control(p=0.007),but serum level of TNF - ? is significantly decrease when compared to both CAD(p=0.023) &healthy control (p=0.0001)although it was non - significant decrease when comper to patient with CHF without cachexia.In the patient with CHF without cachexia, non - significant increase in serum level of adiponectin (when compared to patient with CAD with preserved LVSF& non - significant decrease compare to healthy control), while serum level of leptin was non - significantly decrease (when compared to patient with CAD with preserved LVSF & non - significant increase when compared to healthy control) associated with non - significant decrease in serum level of TNF - ? in comparison to CAD with preserved LVSF but significant decrease compared healthy control(p=0.011)while serum level of IL - 6 significantly increase in comparison to both CAD with preserved LVSF(p=0.01) &healthy control(p=0.008).In CAD with preserved LVSF non - significant decrease in serum level of adiponectin,while non - significant increase in serum level of both leptin , IL - 6 & TNF - ? when compared to healthy control. In this study there is strong significant positive correlation between adiponectin & TNF - ? in patients with CAD with preserved LVSF(r=0.615,p=0.002); while adiponectin was positively correlated with E.F% in patients with CAD with preserved LVSF(r=0.448,p=0.037).Finally there is significant positive correlation between TNF - ? & IL - 6 in patients with CHF with cachexia(r=0.466,p=0.029).CONCLUSIONCachexia, is a catabolic state of CHF associated with increase in serum adiponectin concentration, this may be consider as preservation of physical response to the changes in body fat but might also suggest that adiponectin plays a role in pathogenesis of cachexia, while cachexia associated with HF is not caused by enhance leptin release but, by increased level of adiponectin which is powerful predictor of cardiac cachexia.Cardiovascular Disease(CVD) is associated with elevated marker of systemic inflammation)C - R.P(that plays important role in disease progression& increase level of proinflamnmatory cytokine)IL - 6(has been reported as important pathogenic factor contributed to cardiac injury during CHF& progression to cardiac cachexia, although ,the level of TNF - ? is lower & has no relation to the degree of cachexia

تقييم نسبة الاديبونيكتين والانترلوكين - 6 واضداد البروتين الستروليني في مصل الدم وتركيب الجسم مع الكثافة الكتلوية للعظم لدى المرضى المصابين بالفصال العظمي العقدي Evaluation Of Serum Adiponectin , Interleukin - 6 , Anti - Cyclic Citrulinated Peptide And Body Mass Index With Bone Mineral Density In Nodal Osteoarthritis Patients

المستخلص: الفصا العظمي العقدي هو واحد من انواع التهاب المفاصل الموضعي. هو مرض المفصل التنكسي او الانحلالي, ويشمل الغضروف المفصلي والعظم تحت الغضروف, وهو يعتبر نوع من انواع امراض المناعة الذاتية. السبب الرئيسي للفصال العظمي العقدي غير معروف لكن هناك اسباب متنوعة مثل | Nodal osteoarthritis (NOA) is one type of the localised osteoarthritis that mostly occurs with postmenopausal women. It is degenerative joint disease, including articular cartilage and subchondral bone, it consider type of autoimmune diseases. The main cause of NOA is unknown but there are variety of causes like hereditary and metabolic, may initiate processes leading to loss of cartilage. The cartilage loss process usually lead to induce the immune system to release many of immune factors like cytokines , these factors lead to generation of immune response and inflammation in the joint. The NOA mostly occurs with postmenopausal women. It affects the smaller joint. Over several years, firm knobbly swellings form on the finger joints. These are caused by osteophytes so lead to bony enlargement and are known as Heberden's nodes when they are at the end joints of fingers (distal interphalangeal joints) or Bouchard's nodes when they are at the mid - finger joints (proximal interphalangeal joints). Once the nodes are fully formed, and not necessarily painful, they do limit the movement of the fingers significantly. NOA leads to the formation of bunions, rendering them red or swollen. Some people notice these physical changes before they experience any pain, but in advance cases, many of Symptoms may include like joint pain, stiffness and sometimes an effusion. When bone surfaces become less well protected by cartilage, bone may be exposed and damaged. As a result of decreased movement secondary to pain, regional muscles may atrophy, and ligaments may become more lax.Many studies have been done about inflammatory and biochemical markers in NOA and they found conflicting results. Objective1 - To evaluate serum adiponectin , interleukin - 6 (IL - 6) , anti cyclic citrullinated peptide (ACCP) and bone mineral density (BMD) in NOA.2 - To asses the CRP , RF and ESR in NOA.3 - To asses effect of age , gender , effect of BMI , smoking habit and duration of disease in NOA.Material and Method This study performed during the period from November 2013 to February 2014. These subjects were selected from patients attending the Rheumatology & Rehabilitation Consultation Unit at Al - Yarmouk Teaching Hospital. Patients and controls with hypertension, diabetes mellitus, malignancy, chronic disease of kidney, liver and any patients taken drugs that might effect the results have been excluded from the study.The laboratory tests were done in Al - Yarmouk teaching hospital laboratories and the laboratory research unit in collage of medicine / department of medical biochemistry. Subjects80 subjects (60 patients & 20 healthy controls) were enrolled in this study : A. First group : Patients with Nodal Osteoarthritis (NOA), No. = 60 (female =49 & male =11), rang of age (40 - 88) years.B. Second group : Healthy control group who had no history or clinical evidence of NOA or any other chronic disease like hypertension, DM and other chronic disease that might effect on the study data, No. 20 (female = 15 & male =5 ), rang of age (48 - 82) years.The patients were diagnosed as NOA according to the 2013 American College of Rheumatology (ACR) criteria, also the patients were diagnosed as normal, osteopenia and osteoporosis according to the 2013 American College of Rheumatology (ACR) criteria by measured of BMD (T - score) Normal : T - score (more than or equal - 1), Osteopenia : T - score ( - 1.1 - - 2.5) and Osteoporosis : T - score (less than - 2.5). The patients BMI were measured and determined as Normal (18 - 24.9 kg/m2), Over weight (24.9 - 29.9 Kg/m2), Obese grade - I (29.9 - 34.9 kg/m2) and Obese grade - II (more than 34.9 kg/m2) according to WHO 2012.MethodsELISA technique was used for the determination of serum adiponectin, IL - 6 and ACCP. Measurement of serum uric acid was done by spectrophotometric instrument. qualitative serological tests were used for determination of the CRP and RF also ESR determination were done in hospital laboratory. The BMI was determined by WHO equation's (2012) (weight/ (length) 2), also the BMD was determined by DXA scan according to ACR limits.Results obtained were subjected to statistical analysis by using SPSS and Excel program.ResultsLevels of serum adiponectin, IL - 6, CRP, ESR and BMI were significantly increased in NOA patients most than healthy controls, also the BMD (T - score) significantly decreased in NOA patients than healthy controls. But the age, gender, serum ACCP and uric acid were not significantly changed in NOA patients compared with healthy controls. Study of age, gende , BMI and duration of disease, found that they did not effect any parameters studied in NOA patients, only serum ACCP level was found to be significantly increased in females than males. Serum adiponectin level and CRP were significantly increased more in osteoporosis than osteopenia and normal. CRP was significantly increased in smoker than non smoker NOA patients.This study showed negative correlation between serum adiponectin and BMD, positive correlation between serum adiponectin and ESR, serum adiponctin and IL - 6 and IL - 6 and ESR in NOA patients. This study illustrated change in the status of the inflammatory markers like adiponectin, IL - 6 and other parameters in NOA disease. It illustrated effect of some of the factors like age, gender, BMI, BMD, smoking habit and duration of disease on development of NOA disease and on the status of the parameters studied. Also this study illustrated some correlation between the parameters in NOA patients.

المرضى المصابين بالمتلازمة الشريانية الحاد Vaspin and Omentin - 1 : تقييم مستويات Evaluation Of Serum Vaspin And Omentin - 1 Levels In Patients With Acute Coronary Syndrome

المستخلص: Acute coronary syndrome (ACS) is an insufficient supply of the myocardium with oxygenated blood in which atherosclerosis is an essential cause of myocardial ischemia. Adipokine biomarkers plays an essential role in the atherosclerosis and hence coronary artery disease. Serum Vaspin, Omentin - 1 and troponin I Fast are the biomarkers that believed to be independently associated with acute coronary syndrome.Objective : The study was carried out to evaluate : serum Vaspin,Omentin - 1 and Troponin I Fast in patients with acute coronary syndrome [ST - Elevation Myocardial Infarction(STEMI), Non - ST - segment Elevation Myocardial Infarction (NSTEMI),and Unstable Angina pectoris (UA)], that may help in guiding the diagnosis and treatment.Subjects, Materials and Methods : The study include a total (100) individuals; (75) patients with acute coronary syndrome (ACS) and (25) healthy control.A total number of 75 patients with acute coronary syndrome (ACS) (50 male ,25 female ) as : 25 patients with STEMI (22 male and 3 female) 25 patients NSTEMI(16 male and 9 female ) and 25 patients with unstable angina UA(12 male and13 female)were enrolled in this study all taken from Coronary Care Unit (CCU)at AL - Yarmouk Teaching Hospital.Each patient was clinically examined by the consultant cardiologist and the diagnosis was achieved by electrocardiograph (ECG), and cardiac enzyme levels.Venous blood sample (ten milliliters) was drawn from each patient and control after (10 - 12) hours overnight fasting, using a 10 ml disposable syringe between 9.00 and 11.00 A.M.The sample was divided into two portions one for testing Hb concentration and the other part was centrifuged to obtain serum, to be used for measuring the following variables : serum vaspin, serum omentin - 1 and Troponin I Fast, total cholesterol, triglyceride, High density lipoprotein cholesterol and low - density lipoprotein cholesterol, fasting blood sugar, serum creatinine and uric acid.Body mass index was calculated according to the following equation : BMI=weight/height2, also blood pressure was measured.Results : Serum vaspin and omentin - 1 levels were significantly lower in patients groups in comparison with control group, while serum Troponin I fast, total cholesterol, and low density lipoprotein cholesterol levels were significantly higher in patients with coronary artery disease than controls. Negatively significant correlation was found between serum vaspin and omentin - 1 with (BMI, total cholesterol and troponin I Fast).Conclusion : Serum Vaspin and Omentin - 1 levels were lower in acute coronary syndrome patients in comparison with control group, serum vaspin and omentin - 1 showed significant changes with the development and progression of acute coronary syndrome and would be valuable in the assessment of patients with acute coronary syndrome.Vaspin and Omentin - 1 may be used as a predictor of ACS.

دراسة فرط زيادة الانسولين بالدم والمتلازمة الايضية لدى مرضى داء السكري النوع الثاني A Study Of Hyperinsulinemia And Metabolic Syndrome In Patients With Type 2 Diabetes

المستخلص: مرض السكري من النوع الثاني هو اكثر اشكال مرض السكري شيوعا ويتميز باختلال افراز الانسولين واختلال فعاليته ويكون مصحوبا بمشكله زياده الممانعه للانسولين(وهي الحاله التي يكون فيها كميه الانسولين الطبيعيه تكون غير كافيه لانتاج نفس الفعاليه الايضيه في الخلايا | Type 2 diabetes is the most common form of diabetes and is characterized by disorders of insulin action and insulin secretion, and associated with increase problem of insulin resistant which is the condition in which normal amounts of insulin are inadequate to produce a normal insulin response from fat, muscle and liver cells. Insulin resistance in fat cells results in hydrolysis of stored triglycerides, which elevates free fatty acids in the blood plasma. Insulin resistance in muscle reduces glucose uptake, whereas insulin resistance in liver reduces glucose storage, with both effects serving to elevate blood glucose. High plasma levels of insulin and glucose due to insulin resistance often lead to metabolic syndrome.The combination of hypertension, dyslipidemia, insulin resistance, hyperinsulinemia, glucose intolerance, and obesity, particularly central obesity, has been termed the “metabolic syndrome.” It has been proposed that this syndrome is a powerful determinant of type 2 diabetes and cardiovascular disease.Material and measurements : The study is designed to measure BMI, FBS, TG, HDLc, and c - peptide and insulin level. history of hypertension, age of patients and duration of diabetes are Also taken in to account. These parameters and measures applied for forty five patients with diabetes and thirty normal as control subjects.Results : - There is a positive significant Correlation between insulin level of the diabetic patient and BMI - there is Also a positive significant correlation between insulin level and C - peptide in diabetic patient (r=0.781) (p=0.0001) and in healthy control (r=0.599) (p=0.0001). - There is a positive significant Correlation between C - peptide level of the diabetic patient and BMI - There is a significant negative correlation between HDL with HbA1c, in diabetic patient (r= - 0.423) (p=0.006) and significant correlation of HbA1c with FBS - There is a positive significant Correlation between duration of diabetes and age of the patient(r=0.783) (p=0.0001) - There is a significant negative correlation between C - peptide and duration of diabetes in diabetic patient (r= - 0.310) (p=0.045) - There is a significant correlation between TG with FBS values. - There is a negative significant correlation between TG with HDL values. - 37.8% of diabetic patients had metabolic syndrome and no one of the control subjects had the criteria of (WHO).Conclusion : There were large percentage of diabetic patients with different BMI had metabolic syndrome as compared with the control subjects. There were strong correlations between insulin level (hyperinsulinemia) and risk of metabolic syndrome development and appearance of its complications. The risk of hyperinsulinemia and metabolic syndrome was well correlated with BMI than with HbA1c. Most of over weight and obese patients had high insulin level with different degrees of glycemic control and duration of disease. Large number of patient with metabolic syndrome were hypertensive as compared with diabetic patients with out the syndrome.

مستوى الدلائل الكيمياحياتية ومعاملات الاورام في التمييز بين سائل الاستسقاء السرطاني الخبيث وسائل الاستسقاء غير السرطاني The Level Of Biochemical Parameters And Tumour Markers In The Differentiation Between Malignant From Non - Malignant Ascitic Fluid

المستخلص: الاستسقاء هو مصطلح يطلق على الجهاز الهضمي لتراكم السوائل في التجويف البريتوني (البطني) الناجمة عن كل من الامراض غير الخبيثة مثل تليف الكبد، والتهاب الصفاق السلي... الخ، والامراض الخبيثة مثل سرطان غشاء البطن المنتشر، وسرطان الثدي وسرطان المبيض. لقد تم | Ascites is a gastroenterological term for an accumulation of fluid in the peritoneal cavity caused by both non - malignant disease such as cirrhosis, tuberculous peritonitis..etc, and by malignant disease such as metastatic adenocarcinoma, breast cancer and ovarian cancer. The work in this thesis was done to evaluate the role of the multiple biochemical parameters and group of tumour markers in the differentiation between malignant ascites from non - malignant ascites. A number of parameters were obtained from (60) sixty patients : (30) thirty with malignant ascites and (30) thirty with non - malignant ascites (as controls), all patients admitted to the department of gastroenterology in Medical City - Baghdad Teaching Hospital, Oncology Teaching Hospital and Al - Amal Hospital between December 2013 and July 2014. The biochemical parameters and tumour markers which have been measured in the present study included : total protein, albumin, uric acid, calcium(Ca++), carcinoembryonic antigen(CEA),cancer antigen(CA19 - 9), cancer antigen(CA15 - 3), cancer antigen(CA125) and ? - human chorionic gonadotropin (? - hCG).The statistical analysis for the data obtained in the present study showed : 1 - Highly significant increase of CA15 - 3, ? - hCG and ascitic fluid/serum (A/S) total protein ratio in malignant ascitic fluid while there is significant decrease of serum ascites albumin gradient (SAAG) and serum ascites cholesterol gradient (SACG) in malignant ascites compared with non - malignant ascites patients (p<0.0005, p<0.0005, p<0.05, p<0.0005 and p<0.005 respectively). Thus the level of these parameters in ascitic fluid could be used as a good parameters in differentiation between malignant ascites from non - malignant ascites patients.2 - Significant increase in serum CA15 - 3 and ? - hCG level in malignant ascites patients compared to non - malignant ascites (p<0.05 and p<0.0005 respectively). 3 - Significant increase of CEA, CA19 - 9, total protein, albumin, uric acid and Ca++ level in ascitic fluid of malignant ascites patients compared to non - malignant ascites (p<0.0005, p<0.005, p<0.005, p<0.005, p<0.05 and p<0.05 respectively), thus the level of these parameters in ascitic fluid could be used as a helpful parameters in differentiation between malignant ascites from non - malignant ascites patients. 4 - Significant increase in serum of CEA, CA19 - 9, albumin, uric acid and Ca++ level in malignant ascites patients compared to non - malignant ascites (p<0.05, p<0.05, p<0.05, p<0.05 and p<0.05 respectively) while there is no significant differences in serum total protein level of malignant ascites compared to non - malignant ascites (p>0.05). 5 - CA125 level in ascitic fluid and serum of malignant ascites patients shows no significant increase compared to non - malignant ascites (p>0.05 and p>0.05 respectively), therefor CA125 test in ascitic fluid cannot be used as a parameter in differentiation between malignant ascites from non - malignant ascites patients.CA15 - 3, ? - hCG, (A/S) total protein ratio, SAAG and SACG can be considered as a good parameters in differentiation of malignant from non - malignant ascites, while CEA, CA19 - 9, total protein, albumin,Ca++ and uric acid level in spite of their increase in malignant ascitic fluid but this increase is not considered as a diagnostic factor and can be used as a helpful parameters in the differentiation between malignant from non - malignant ascites. CA125 has no useful role in diagnosis or differentiation between malignant from non - malignant ascites.

المستخلص: المقدمة : يعرف الاسقاط المهدد بانه حالة يمكن ان تصيب معظم النساء الحوامل في بداية الاشهر الثلاث الاولى من الحمل ,يتميز بحدوث نزيف مهبلي مصاحب بالام في البطن والظهر ويمكن ان ينتهي اما بحدوث اجهاض فعلي وموت الجنين او اكمال اشهر الحمل والانتهاء بالولادة.الهدف | Threatened abortion can defined as failure of pregnancy and vaginal bleeding and this occur before twentieth weeks of pregnancy. Aim of study : To evaluate association between maternal serum levels of angiogenic growth factors (sFlt - 1 & PlGF) with threatened abortion by compare it with control healthy level, to evaluate association between maternal serum level of oxidative stress marker (Glutathione peroxidase) with threatened abortion by compare it with control healthy level. To investigate if maternal serum levels of these parameters can be used as predictive markers for outcome of threatened abortion. Subjects & Method : Eighty six women were included in this study with age range from (20 - 35) years, all women attended to Obstetrics and Gynecology department / Alyarmook hospital during period from December 2015 to March 2016.Subjects were divided into three groups(1)Non pregnant women (in luteal phase) : 16 women serve as control group ( 2) Normal pregnant women with gestational age between (6 - 12) weeks : 20 women serve as patient study group(3) Threatened abortion women with gestational age between (6 - 12) weeks with vaginal bleeding : 50 women serve as patient study group. All threatened abortion women had been followed up for 6 months to determine whether they complete their pregnancies with live birth or subsequent miscarriage. Women with or without history of previous abortion, cigarette smoking were included and excluded women with age below 20 years and above 35 years or with diseases like (Hypertension, Diabetes mellitus, Hyperthyroidism) and women in follicle phase. All serum samples were analyzed for soluble fms - like tyrosine kinase - 1 (sFlt - 1), placental growth factor (PlGF) and Glutathione peroxidase by using (ELISA) technique.Results : There was significant lowering in mean value level of sFlt - 1 in threatened abortion women (8.5 ± 4.4 ng/ml) than normal pregnant women (13.8 ± 3.2 ng/ml)and non - pregnant women (15.3 ± 3.2 ng/ml), P value
