Abstract: ان من الحقائق العلمية الثابتة اليوم ان الفحص الروتيني للسائل المنوي يعد عاملا تنبؤيا اجماليا للقدرة الاخصابية للرجال، ولذلك فان حاجة متزايدة بدات تبرز لاكتشاف فحوصات وظيفية جديدة في عملية تقييم العقم عند الرجال. ان الهدف الاساس من هذه الدراسة هو تعزيز الج | It is a scientific fact today that routine seminal fluid analysis is a key predictor of male reproductive potentiality ; so that there is an increasing need for finding out other functional tests in the assessment of male infertility. The main goal of the current study is to consolidate the scientific and practical efforts concerned with male infertility assessment especially from immunological and genetic aspects. The study was carried out between January 2013 and December 2013 including one hundred (100) selected infertile men who attended the Fertility Center in al - Sadr Medical City in Al - Najaf Al - Ashraf Governorate, the study also included twenty (20) healthy volunteer fertile men as a control. Serum and seminal antisperm antibodies (ASA) were determined by ELISA (Enzyme Linked ImmunoSorbent Assay) technique ; sperm chromatin condensation was evaluated by aniline blue staining (AB) ; sperm DNA fragmentation (damage) was evaluated by toluidine blue staining (TB). The results showed that the incidence and concentration of serum and seminal plasma ASA in the infertile men were significantly (p<0.05) higher than that in control fertile men. The incidence and concentration of serum and seminal ASA were also significantly (p<0.05) higher in normozoospermic infertile patients than that in control fertile men. There was a high significant negative correlation (p<0.01) between the concentration of serum and seminal plasma ASA in the infertile men and sperm motility and progressive motility, the concentration of serum and seminal ASA also showed a high significant positive correlation (p<0.01) with sperm agglutination, and a significant positive correlation (p<0.05) with seminal WBC count. The results also revealed that there were no significant effects (p>0.05) for patients' age, infertility duration, ABO blood groups and smoking habits on the levels of ASA in the serum and seminal fluid, while higher significant increase (p<0.01) in serum and seminal ASA concentrations was observed in infertile patients with varicocele as compared with those without. The results have also revealed that the percentage of sperm with chromatin decondensation and DNA damage has shown a high significant (p<0.01) increase in infertile patients compared to fertile men. There was also a significant increase (p<0.05) in sperm DNA damage in normozoospermic infertile patients comparing with fertile men, but no significant difference (p>0.05) was found in sperm chromatin condensation between normozoospermic patients and fertile men. Both sperm chromatin decondensation and sperm DNA damage showed a significant positive correlation (p<0.05) with sperm morphology, and a significant negative correlation (p<0.05) with sperm concentration, motility and progressive motility. The present study also revealed that the level of chromatin decondensation has been affected by patients' age, infertility duration, smoking habits and varicocele. It was observed that the higher percentage of chromatin decondensation was recorded in patients older than 37 years, and in patients subgroups with infertility duration more than 15 years, it was also higher in smoker as compared with non - smoker patients and in those with varicocele as compared with those without. Similarly, the level of sperm DNA damage has also been affected by patients' age, smoking habits and varicocele. It was observed that the highest percentage of sperm DNA damage was recorded in patients older than 37 years. The highest level of sperm DNA damage was also seen in smoker patients as compared with non - smokers and in those with varicocele as compared with those without. In contrast, the effect of infertility duration on sperm DNA damage was not statistically different (p>0.05). The correlation and regression results recorded high significant correlations (p<0.01) between serum ASA and seminal plasma ASA, and between sperm chromatin decondensation and sperm DNA damage. However, there was no significant correlation (p>0.05) between the level of serum and seminal ASA and each of sperm chromatin decondensation and sperm DNA damage. The current study concluded that the defects in sperm chromatin status (chromatin decondensation and DNA damage), and the immunological disorders caused by serum and seminal plasma ASA may - at least partially - contribute to the etiology of infertility of the patients under study, even in those with normal seminal parameters. However, it seems that ASA affect fertility in a pathway that is different from that affected by sperm chromatin defect. It was recommended that both sperm chromatin staining techniques and ASA tests could be routinely used as complementary tests to diagnose infertility.

Abstract: This study has been conducted for the first time in Najaf / Iraq, and the study included the preparation of a local inactivated vaccine (whole and subunit).The number of cases infected with seasonal influenza virus were 647 cases out of one thousand suspected case. They were distributed into eleven groups. Seasonal influenza virus was detected by two diagnostic methods (rapid test device and real time PCR).The present study has reflected that the most diagnosed cases infected with seasonal influenza virus during the period extended from March 26, 2012 up to April 30, 2013 represented by were type A (H3N2) (283) cases. Whereas H1N1 (148) cases, H3N2+H1N1, (56) cases, H1N1 + H3N2 + B were (30) cases and 130 cases were infected with type B.Current study also revealed that age group of 46 - 60 years old infected with seasonal influenza virus were (159) case including (368) male and females were (279) of different infected group..The spread of seasonal influenza virus in Najaf varies from one region to another depending on the population density. Clinical cases were collected randomly during the months of the year. It has been found that the spread of disease has something to do with temperature and humidity as high humidity and low temperature lead to increased spread of the disease because of their relationship at the stage of the spread of epidemic influenza that spread from Dec 26, 2012 and up to April 1, 2013 in addition to expatriates infected..Two techniques were used for isolation of seasonal influenza virus first inoculation of embryonated chicken egg and secondly chicken fibroblast cell culture.It was found that at the embryonated egg lethal dosage (ELD 50 / 0.5 ml) (109.6) whereas tissue culture infective dosage (TCID50 / 0.1 ml) was (109.3) of (H1N1+ H3N2) and type (B) virus..Virus was purified by two ways that are depending on the vaccine type. The gamma irradiation that dosage used for inactivating vaccine of the purified virus which was extracted from allantoic fluid and tissue culture was (5.702) mSv/h for subunit virus vaccine type whereas gamma irradiation dosage for complete (whole) virus vaccine was (8.816) mSv/h. The results proved that immunoglobulins (IgM, IgA and IgG) levels as well as (IL - 17, IL - 10 and INF - 1?) indicated significant differences among vaccinated, infected and control groups.Subunit and whole virus vaccine extracted from chicken fibroblast cell culture are considered the best of derived from virus propagated in embryonated chicken eggs.Subunit virus vaccine is better than the whole virus vaccine derived from virus propagated in embryonated chicken eggs and extracted from chicken fibroblast cell culture.The current study also reflected that locally prepared virus subunit vaccine and purified whole virus killed vaccine capable of inducing humoral and cellular immune response in experimentally vaccinated rats..Histopathological changes appeared clearly on tissue sections (lung, trachea, heart, liver, spleen, kidney) of the infected group as compared with control and the vaccinated groups.

Abstract: ا جريت هذه التجربة في قسم علوم الحياة / كلية العلوم / جامعة الكوفة في محافظة النجف الاشرف وتضمنت مرحلتين : الاولى زراعة البذور لغرض قياس نسبة الانبات للمدة من 1 / 8 لغاية 8 / 8 / 2011 وانتاج الشتلات للمدة من 15/8/2011 ولغاية 14 / 9 /2011 في حقل خاص لانتا | This experiment was conducted in the Department of Biology, College of Sciences, University of Kufa in Al - Najaf Al - Ashraf province. It included two periods : the first was seed sowing to measure germination percentage from 1 - 8 till 8 - 8 - 2011, and transplants production from 15 - 8 - 2011 till 14 - 9 - 2011 in a private farm for vegetable transplants production. The second was transplanting in an open field belongs to Plant Production Department/Kufa Technical Institute from 15 - 9 - 2011 till 17 - 1 - 2012 to measure plant growth parameters and curd cauliflower production cv.solid snow in harmless environment techniques. The experiment was adopted as factional experiment. The treatments were distributed according to Randomized Complete Block Design (RCBD) with four replicates. The experiment included the study of two factors : the first, was five magnetic intensities for treating waters magnetically (0; 500; 750; 1500 and 2500 Gauss) by means of dipolar magnetrons. The second was three quantities of plant organic manure(rice residues).i.e.(0, 2.5 and 5.0 kg/furrow) with a length of 6.5 m. and their interactions on growth and production the yield of cauliflower, cv.solid snow. Duncan's Multiple Range Test (DMRT) was used to compare means at probability of0.05. Correlation and regression coefficient were also used to evaluate the relationships between studied parameters and time. Vegetative growth parameters that are measured were : plant leaf number ; stem height; stem diameter; plant leaf area; leaf fresh and dry weight; stem dry weight; plant shoot fresh and dry weight. Flowering parameters were : curd fresh and dry weight and curd diameter. The results could be summarized as following : 1. Water chemical analysis showed that irrigation with magnetized treated water had an effect on physical properties, nevertheless, was more or less affected ions components. 2. The use of magnetized treated water in irrigation resulted in an increase in germination percentage of cauliflower seeds cv. Solid snow.The highest germination percentage was obtained from magnetic intensity of 1500 Gauss in both experiments, laboratory and field that reached 71.14 and 65, 62%, respectively on the base of Arc Sin. 3. The use of magnetized treated water in plant irrigation at all the used intensities resulted in an early emerged curd cauliflower by 15 days compared with control treatment plants. 4. 750 gauss magnetized treated water achieved at age of 138 days from transplanting, the highest plant leaf area mean is (4836.2 cm2) with percentage increase of 51.7% compared to control treatment plant leaf area (3188.3 cm2).That effect was reflected on curd weight. 5. 1500 and 2500 Gauss magnetized treated water treatments at earlier ages increased the values of vegetative growth parameters which reflected its effect on flowering growth parameters by shorter time of curd irritation, compared with the effect of 500 - 750 Gauss at earlier ages , which are in spite of its late effects produced at 150 days old from transplanting particularly 750 Gauss the highest mean of curd fresh weight. 6. 750 Gauss magnetized treated water achieved the highest yield reached 22.2 ton/h. which differed from that productivity gained from control treatment plant(9 - 29 ton/h.) with percentage increase of 138.8%. 7. Organic plant manure addition at both quantities(2.5 and 5.0kg/furrow) resulted in an increase in both vegetative and flowering growth parameters compared with untreated plants. 5 kg/furrow treatment produced the highest means compared to control treatment particularly at the age of 138 days in all vegetative growth parameters. 8. The addition of 5 kg/furrow at age of 150 days produced the largest curd fresh weight 918.4 g. and diameter of 17.2 cm which statistically differed to compared plant treatment that produced 506.0 g. and 13.3 cm. for curd fresh weight and diameter at the same age respectively. 9. 5 kg/furrow organic manure addition resulted in a highest productivity of 21.6 ton/h. compared to that of control treatment of 11.9 ton/h. with an increase of 81.5%. 10. Interaction between irrigation water magnetically treated with 750 Gauss and addition of (organic manure with 5 kg/furrow) at the age of150 days resulted in the highest curd fresh weight of 1292.9 g. with curd diameter of 20.3 cm. compared to that plant of control treatment produced curd fresh weight of 292.5 g. and 11.0 cm. diameter. This interaction also produced 30.3 ton/h. for (750 Gauss×5 kg/furrow) compared with the productivity of control treatment plants that gave 6.86 ton/h. with percentage increase of 341.6%

The identification of the Enterococcus spp. isolates were depended on colonial morphology, microscopic examination and biochemical tests as a primary identification. The final identification was performed with the automated VITEK - 2 compact system using Gram positive - Identification (GP - ID) cards.According to the results obtained by the VITEK tests forty two clinical isolates of Enterococcus were detected, which distributed into : (22) isolates from urine, (8) vaginal swabs, (6) seminal fluid, (4) throat swabs and two isolates from wound swabs with no isolates from cerebral spinal fluid, stool and blood specimens.This study revealed that the E. faecalis is more distributed with 25(59.52%), followed by E. faecium with 10 (23.80%), E.avium with 5 (11.90 %), E. durans and E. raffinosus with 1(2.39%) for each.The study investigated the virulence factors of E. faecalis, E.faecium and E.avium, which play a major role in enterococcus pathogenicity. E. faecalis and E.faecium had the ability to producecapsule, gelatinase, biofilm, adhesion, protease, bacteriocin, haemolysin and cytolysin except ? - lactamase produced only by E. faecalis while E.avium produced all these virulence factors except gelatinase, bacteriocin and cytolysin.The results revealed variation in the resistance of bacteria to antibiotics, E.faecalis express absolute resistance (100%) to Erythromycin, high resistance against Gentamycin, Tetracyclin and Vancomycin but high susceptibility to Ciproflaxacin and Penicillin and moderate susceptibility to Chloramphenicol. E.faecium exhibited absolute resistance (100%) to Erythromycin, Gentamycin and Tetracyclin, high resistance against Chloramphenicol, Penicillin and Vancomycin but high susceptibility to Ciproflaxacin while E.avium exhibited susceptibility (100%) to all these antibiotics except Tetracyclin showed absolute resistance.Then detected the virulence factors encoding genes : efaA, esp, eep and enlA genes by using PCR techniques and Electrophoresis Systems.Finally, The genotypic method. Regard to genotypic study the outcome showed that 21(84%) isolates of E.faecalis, 4(40%) of E.faecium and 5(100%) of E.avium were carrying efaA gene and 17(68%) of E.faecalis, 5(50%) of E.faecium, 5(100%) of E.avium were carrying esp gene while eep gene was carrying only by E.faecalis and E.faecium ; 12(48%) and 3(30%) respectively. Also the results revealed that only 1(4%) isolates of E.faecalis have enlA gene.

Abstract: The study aimed to investigating the role of coagulase - negative staphylococci in human infections, and determining the predominance genes of the virulence factors. Three hundred clinical specimens were collected from out and inpatients undergoing catheter related infections and twenty specimens were collected from healthy hospital staff as a control from January 2013 to July 2013 of Al - Zahraa Teaching Hospital, Al - Sader Teaching Hospital and Al - Hakeem Hospital in Al - Najaf Al - Ashraf province. The specimens were included urine, blood, vaginal swabs, seminal fluid and wound swabs. The specimens were cultured on mannitol salt agar and the primary identification was depended on Gram stained and biochemical tests. Then finally identification with Vitek 2 system is done.One hundred isolates were identified as coagulase - negative staphylococci (CoNS), Staphylococcus haemolyticus was identified as the most frequently isolated species in (53%), followed by Staphylococcus epidermidis (26%) and Staphylococcus hominis were recorded in (21%). Most of CoNS isolates were highly resistance to penicillin G (benzylpenicillin), oxacillin, cefoxitin and erythromycin; and low resistance to rifampicin, levofloxacin and others. While, control isolates results showed moderate resistance to penicillin G and erythromycin; low - level of resistance to cefoxitin, oxacillin and other antibiotics.The investigation of virulence factors revealed that 93% of coagulase - negative staphylococci isolates were production of slime layer, DNase 58%, protease 29% and hemolysin 88%. But the results gave negative result for TNase and lipase enzymes.Monoplex and multiplex PCR were used to explore the MecA, aap, icaA, icaD, atlE, sea, seb, sec, sed, hla, hlb, sspA, sspB, geh, nuc genes. The results showed that all CoNS isolates (100%) had mecA and atlEgenes, but 98% of isolates had aap, 93% icaA and icaD genes. PCR revealed that only (14%) of isolates had genes for enterotoxins expression. (92.86%) and (7.14%), sea and seb respectively, in contrast, the sec and sed genes were not be recorded.The result showed that 47% of CoNS isolates had hla gene and 41% contain hlb gene, 29% were positive for the sspA gene whereas the sspB gene and geh and nuc2 genes not found in any of staphylococcal isolates. Finally, the result indicated that 58% of CoNS isolates were expressed the nuc1 gene.Plasmid curing was carried out in order to determine the origin of resistance and some virulence factor genes (chromosomal or plasmid - borne gene). The curing (elimination) of the plasmids of coagulase - negative staphylococci isolated was catalyzed using ethidium bromide in different concentration and high temperature (44?C). The results showed that the oxacillin resistant coagulase - negative staphylococci were plasmid mediated since 93% of the isolates showed negative result on oxacillin resistance screening agar, and absence of mecA gene from all isolates. Also, 41 of coagulase - negative staphylococci isolates that showed ? - hemolysin became non - hemolysin after manipulated with ethidium bromide.Finelly, taking into consideration the etiological importance of CoNS has often been neglected, the present investigation confirmed that these microorganisms should not be ignored or classified as mere contaminant.

(AMH) has glycoprotein dimmer structure.AMH is produced by the granulose cells. AMH level in the plasma of PCOS patient are two or three times higher than average and begin to decline five years later than healthy womenObjectivesThe main objective of the study is to estimate the AMH level as a prognostic factor in PCOS infertile women on ovulation induction, also to describe some risk factors of infertility and their association with the AMH level.MethodologyA cross sectional study has been carried out in the outpatient clinic at Al Sadr infertility center under supervision of specialist gynecologist on 60 patients. The data has been collected by a questionnaire which contains demographic characteristics, gynecological history, physical examination and some laboratory investigations. The data collected by simple random to select the case from the outpatient clinics in the fact of 4 - 5 infertile women one day/week, then a period of time required for following up them after the ovulation induction The data have been collected during the period from the 1st of February till the 30 of September 2015.ResultsThere was a high statistically significant difference (P 0.000) in mean AMH among the cases with negative PT from those with positive PT, also the higher level of AMH strongly linked (P 0.023) with the presence of acne as a symptom of PCOS. There was no correlation of AMH with the age, LH, FSH, prolactin, TSH, size of dominant follicle and infertility duration. While it was positively correlated (P 0.000) with the age of menarche, BMI (P 0.000), Serum testosterone (P 0.002) andendometrial thickness (P 0.000).Conclusions & RecommendationsAMH is a useful test to study folliculogenesis and ovarian potential in various situations of infertility and for identification of PCOS. High levels of AMH are commonly associated with pregnancy failure.So, a recommendation of AMH level measuring for all PCOS patients should be done in order to know the prognosis during the ovulation induction.

These women and their infants contribute significantly to obstetric &neonatal health care costs. The prediction of delivery latency could help direct the need for specific interventions such as hospitalization, intensive monitoring, timing of antenatal steroids.Objective : To determine whether transvaginal CL, AFI,or a combination of both can predict delivery latency within 7 days in women presenting with PPROM.Methods and Study Design : This was a prospective observational study of TVCL measurements in 80 singleton pregnancies with PPROM between 24 - 34 weeks. Transvaginal ultrasonography was performed with TOSHIBA SSA - 340A(Tokyo - Japan) apparatus 7.5MHz transvaginal probe, to measure the CL&AFI. Delivery latency was defined as the period from the initial TVCL after PPROM to delivery of the baby with our primary outcome being delivery within 7 days of TVCL. The independent predictability of significant characteristics for delivery within 7 days was determined using multiple logistic regression.Sensitivity, specificity, and predictive values were used to determin, whether the presence of a short TVCL, AFI or a combination of both affected the risk of delivery within 7 days.Result : Our study in women with PPROM show the validity of CL in predicting labor when the cut off value2cm the sensitivity=52.6%, specificity=69%, PPV=60.6%, NPV =61.7% and Accuracy=61.25%.The validity of AFI when the cut off value 5cm the sensitivity=71.1%, specificity=50%, PPV=56.3%, NPV=65.6% and Accuracy=60%.With combination of CL&AFI in predicting time of labor after PPROM the sensitivity=50%, specificity=92.8%, PPV=86.4%, NPV=67.2% and Accuracy 72.5%.In women with PPROM the rate of gestational age ? 30 weeks that labored within 7 days 44.7% and those labored more than 7 days 55.3%.Also the rate of gestational age >30 weeks that delivered within and after 7 days are 50%.According to the parity we found the mean value of those delivered within 7 days are 1.24 and those after 7 days are 1.28.Conclusion : Our study shows there is increase in positive predictive value when combination of AFI and CL in prediction of time of labour so women with AFI?5 and CL?2 had 86.4% risk of delivery within 7 days after PPROM. Also the study found there was no significant association between gestational age, or parity with the prediction time of labor.

Male factor infertility accounts for 50% of all cases. The key responsibility of assisted reproductive technologies (ART) is the management of male infertility by bypassing seminal fluid disorders. Defective Sperm parameters were responsible for deciding the fertility potential and related to pregnancy rate in vivo as well as in vitro.Today, the classic seminal fluid analysis is found to be of limited importance in describing a couple’s fertility status. There is now clinical evidence to show that damage to human sperm DNA may adversely affect reproductive outcomes and the spermatozoa of infertile men possess substantially more DNA damage than do spermatozoa of fertile men and there appears to be a threshold of sperm DNA damage beyond which embryo development and pregnancy are impaired.In view of that, the aims of the present study were : Evaluation of the influence of defective sperm parameters including concentration, morphology and motility on intracytoplasmic sperm injection (ICSI) outcome represented by fertilization rate, cleavage rate, embryo quality and pregnancy rate. Assessment of the sperm chromatin maturity in infertile men using acidic aniline blue stain and compare it with that of men with normal spermiogram. Discovering the relationship between sperm chromatin status and the semen parameters in infertile males. Finding the relationship between sperm chromatin status and ICSI outcome.This study included 60 infertile couples complaining from either primary or secondary infertility attended the clinics of infertility treatment center and underwent intracytoplasmic sperm injection.They were classified according to their spermiogram to normozoospermic group (N), whose female partner had bilateral tubal block, oligoasthenoteratozoospermic group (OAT) and finally, asthenoteratozoospermic group (AT). The female partners of the last two groups had normal reproductive function according to gynecological examination and laboratory investigations. All female partners included in this study were less than 35 years old to minimize the influence of advanced maternal age on ICSI outcome. Seminal fluid analysis were done for all and aniline blue stain was used in this study to evaluate sperm chromatin integrity. The main results of this study showed that infertile couples with impaired sperm parameters show high percentage of positive aniline blue stain i.e., sperm chromatin maturity defect and it is significantly higher than that in couples with normal spermiogram. The best cut off point of positive chromatin percentage associated with pregnancy was 40% i.e., when sperm chromatin abnormality exceeds 40% as detected by aniline blue staining method; the pregnancy rate start to regress. No significant differences in fertilization rate, cleavage rate, embryo quality and pregnancy rate were found among studied groups.No significant difference in ICSI outcome including pregnancy rate between couples with high percentage of sperm chromatin damage ?30% and those with low percentage of sperm chromatin damage < 30% were found. So the main conclusions are : Defective sperm parameters and chromatin immaturity are significantly associated with each other.Forty percent is the threshold of sperm chromatin immaturity after which ICSI outcome deteriorate and depending 30% as a threshold in this study revealed no significant difference in ICSI outcome among studied groups. Intracytoplasmic sperm injection has corrective and therapeutic role for defective sperm parameters and shows a unique capability to treat the most difficult cases of male infertility.

Abstract: تعد فحوصات وظائف الرئتين من الوسائل المفيدة جدا لاغراض التشخيص والمتابعة والبحث العلمي للاصحاء ومرضى الجهاز التنفسي. وابسط تلك الفحوصات واكثرها معلومة هو الفحص السبايرومتري الذي يتضمن قياس السعة الحيوية القسرية (FVC) , وحجم الزفير القسري في الثانية الا | Lung function tests are very useful diagnostic, follow up and research measures for healthy and respiratory compromised subjects. The simplest, yet the most informative, lung function tests are the spirometric tests.They involve the forced vital capacity (FVC), the forced expiratory volume in first second (FEV1) and the forced expiratory volume ratio (FEV%). Several types of devices are used to perform spirometric tests based on the measurement of lung volumes and their subdivisions. Lung volumes, hence, are represented by the volume of expired air. There was a controversy about the difference between body and ambient temperatures which may extremely affect gas volume , but this is thought to be solved by temperature correction. Temperature correction, however, may not be the precise solution in extremely fluctuating environmental temperatures. A fixed amount of expired gas has a constant mass despite the changes in pressure or volume as is implied by the law of conservation of mass in a closed system by Antoine Lavoisier. The aim of this study is to construct and evaluate a simple device called expiratory gas mass device as a reliable, reproducible, accurate and convenient tool to substitute Vitalograph spirometer as a measure of lung function in healthy Iraqi subjects and testing the hypothesis that expired gas mass could significantly and acceptably alternate or conjugate its volume as measures of lung function. The design of the study is a cross sectional study. The statistically required number of participants was decided by a professional statistician to be 70 healthy subjects. However, 300 healthy subjects are included in the present research to cover the need for subgrouping (146 male and 154 female) aged 20 - 50 years (31.84 ± 9.28 years). The male and female were classified into three age groups for each one, ten years interval was considered to be suitable for classifying subjects.Subjects with abnormal lung function such as smokers were excluded. A uniform case sheet was assigned for every participant in the study which includes, name, gender, age, weight, height, smoking habits, residence, cultural status, socioeconomic status, present and past medical history, family history of respiratory illnesses. They were asked to perform the forced expiratory maneuver through the standardized spirometer and then through the newly constructed gas mass device.The accuracy (systematic error) and reproducibility (random error) were tested for the constructed gas mass device.A comparison between forced vital capacity (FVC) and adjusted gas mass (AGM) was made on two main groups , the male group and female group, both of them were subdivided to three age groups.The results revealed that there were no significant differences in values of FVC and AGM measured by standard Vitalograph spirometer and gas mass device respectively. Regression lines indicated that there were strong positive correlations between gas mass (GM) and FVC in male and female. Separate data for male and female are processed and the results indicated that FVC values and GM (or AGM) values are significantly higher in male than in female , P?0.05. Regression lines indicated that there was a negative correlation between age and both of FVC and GM, a positive correlation between height and both of FVC and GM and a weak positive correlation between weight and both of FVC and GM. From the present study, it can concluded that gas mass device is simple, portable and easily handled device. It is also reproducible and accurate device for the measurement of GM in normal subjects.

Clinically, it affects the most distal extremities first resulting in a stock and glove pattern of sensory loss. It affects both small fibers (myelinated and un - myelinated) as well as the large myelinated nerve fibers. However, the earliest manifestations might be due to small fiber dysfunction. Hyperglycaemia and subsequent metabolic derangement is the main pathogenitic factor of DPN. However, oxidative stress, deficiency of neuroprotective factors and neurovascular insufficiency might play a role.AIMS : This study aims to : 1. Test the value of applying SFEMG in the diagnosis of diabetic peripheral neuropathy. 2. Determine the usefulness of SFEMG, compared to the standard NCS, in the early diagnosis of diabetic peripheral neuropathy. 3. Evaluate the correlation of the antioxidant/oxidant status in patients with and without diabetic peripheral neuropathy.Materials and methods : The study was conducted in the period from Nov. 2012 till Apr. 2014 and included 188 patients with type 2 DM that fall within age group of 45 - 65 years. Diabetics that suffer from clinical features of peripheral nerve dysfunction documented with abnormal electrophysiological findings were considered as patients with DPN (138 patients) and those who had no complaint of peripheral nerve dysfunction with normal electrophysiological study were considered as patients without DPN (50 patients). The study also included normal healthy persons who their age and gender matched that patients and considered as control subjects (50 persons). The patients and control enrolled in the study had undergone comprehensive assessment that included : clinical assessment (history and full examination), biochemical assessment (measurement of fasting blood sugar, glycated haemoglobin, total antioxidant capacity and advanced glycation end products) and electrophysiological assessment that included sensory and motor nerve conduction studies (NCS) with single fiber electromyography (SFEMG).Results : The study found that patients with DPN in comparison to patients without DPN and control subjects are older (p?0.05), had longer duration of DM (p?0.01), poorer glycemic control reflected by fasting blood sugar (p?0.01) and glycated haemoglobin (p?0.01), lower level of total antioxidant capacity (p?0.01) and higher advanced glycation end products level (p?0.01). Also, the study showed that the level of total antioxidant capacity and advanced glycation end products on one hand were correlated with the duration of the diabetes (p?0.01) and not correlated with glycated haemoglobin level on the other hand.The electrophysiological findings showed that patients with DPN had significant differences in NCS parameters when compared to patients without DPN and to control subjects in the form of axonal degeneration and demyelination with abnormal single fiber jitter and fiber density which were correlated with the duration of diabetes (p?0.01) but not correlated with glycemic control. Also the study demonstrated that SFEMG findings were correlated with NCS parameters (namely sural nerve) in patients with DPN. This study had concluded that the duration of diabetes, age, glycemic control and oxidative stress are important risk factors of DPN. Routine NCS is important mean for diagnosing DPN but it has limited sensitivity in the diagnosis of early stages of the disease and in assessing nerve degeneration and regeneration. Sensory nerves of lower limbs are helpful in discovering early stages of DPN when other tested nerves are normal. SFEMG examination in diabetic patients is important in showing the degree of re - innervation and nerve regeneration and in identification of subclinical nerve dysfunction.

Abstract: يعتبر داء السكري المصاحب للحمل هو احد مضاعفات الحمل الاكثر شيوعا والتي ترتبط بمعدلات هامة من الاعتلال والوفاة ما حول الولادة , ان العلاج الفعال لداء السكري ما قبل الحمل ولداء السكر المصاحب للحمل قد تبين تحسين النتائج والحد من وفيات ما حول الولادة بالمقارن | Diabetes mellitus complicating pregnancy is one of the most common antenatal complications that are associated with significant perinatal mortality and morbidity(Magee et al., 1993, Schmidt et al., 2001and Platt et al., 2002). Effective treatment of pre - existing as well as gestational diabetes mellitus was shown to improve outcome and reduce perinatal mortality, as compared to untreated patients (Lao TT, et al., 2001and Langer , et al., 2005). Doppler studies have conventionally been utilized for fetal surveillance. The use maternal uterine artery Doppler as a screening tool to predict subsequent development of pre - eclampsia and fetal growth restriction in later gestation have gained acceptance in recent years. Umbilical artery Doppler, middle cerebral artery Doppler have been widely used for the assessment of growth restricted fetuses. The role of Doppler study in diabetic pregnancies has not been unequivocally evaluated. An atherogenic factor, that promotes vascular endothelial growth, insulin - like growth factor - 1 has been implicated with micro vascular complication during pregnancy (Kathryn 2000). Presently, short - term beneficial metabolic effects of recombinant human insulin - like growth nfactor - 1 (rhIGF) - 1 therapy have been demonstrated in numerous diabetic conditions, including type 1 diabetes mellitus, type 2 diabetes mellitus. Until recently, insulin - like growth factor - 1, based upon its endothelial growth promotion, was considered a mediator of vascular disease( Bayes - genis et al., 2001a; 2001b). Conversely, increasing evidence indicate the protective mechanism of insulin - like growth factor - 1 against vascular derangements, relating to its ability of nitric oxide production (Okura et al., 2001). We sought to investigate the impact of insulin - like growth factor - 1 levels on maternal/fetal blood flow in diabetic non - hypertensive pregnant women; an avenue of research that has yet to be fully explored. Taken together, this information will materialize the intervention needed to prevent or at least ameliorate diabetes maternal and fetal outcomes. OBJECTIVES1 - To evaluate effect of diabetes mellitus on utero - and cerebro - placental Doppler velocimetry in pregnant women, such as resistive index (RI), pulsatility index (PI), Systolic/diastolic ratio (S/D)2 - To find whether a meaningful correlation exists between the above mentioned parameters and the levels of HBA1c and maternal IGF - 1.3 - To predict the most sensitive parameter detecting complications of diabetes mellitus on fetal outcomes. MATERIAL AND METHOD In this prospective cohort study a total of 190 pregnant women with single viable fetus, cephalic presentation, were enrolled after having their verbal and written consent and approval of the ethical committee at Faculty of Medicine. They were divided into two Groups : group (Ia) women with gestational diabetes mellitus (n=70), group ( Ib ) women with pre - gestational diabetes mellitus (n=64) and the remaining (n=56) participants (group II) were free from diabetes and hypertension and served as a control group. The study performed at Al Ameer Diagnostic Center in Al Najaf, between March, 2013 and August, 2014.Examination of the participants done twice, in the second and third trimesters. In each time, history and clinical examinations performed with Doppler ultrasonography of the pregnant women including interrogations of bilateral maternal uterine arteries, fetal umbilical and middle cerebral arteries in addition to measurement of IGF - 1 and HbA1c concentrations. RESULTS AND CONCLUSIONS 1 - IGF - 1 mean± SD in second trimester was 582.61± 183.7 ng/ml in group Ia, 429.5± 231.3 ng/ml in group 1b and 278.6 ± 60.8 ng/ml in the group II with significant difference among the groups (P=0.0001) In the third trimester the mean± SD was 653.69 ±197.6 ng/ml in group Ia, 487.5± 242.4 ng/ml in group Ib and 316.6 ± 60.9 ng/ml in group II with significant difference among the groups (P=0.0001).2 - HbA1c mean± SD in second trimester was 6.59± 0.89 % in group Ia, 6.42 ± 0.9% in group Ib and 5.35 ± 0.56 % in group II with significant difference between group Ia and group II, as well as between Ib and group II, but no significant difference between Ia and Ib groups.Third trimester HbA1c mean value was 6.29 ± 0.78 % in group Ia , in group Ib 6.27 ± 0.87 % and 5.08 ± 0.57% in group II.There was no significant difference between group Ia and Ib (P=0.843) , while there was a significant difference between group Ia and group II as well as between group Ib and group II(P=0.0001).3 - Uterine artery Doppler velocimetry was considered more sensitive predictor than other arteries in evaluation of fetal outcomes and its sensitivity in the total studied population (190) was 44.3%, in gestational diabetic pregnancy group was 58.3%, in pregestational diabetic pregnancy 34.3% and in control was 29.4%.4 - Multiple maternal and fetal arterial Doppler studies at same time yield high predictive values in evaluation of fetal outcomes with general sensitivity in the total studied population was 63.6%, specificity 79.4%79, PPV 72.2% and NPV 71.7%. In gestational diabetic pregnancy the sensitivity was 94.4%, specificity was 61.8%, PPV was 72.3%, NPV was 91.3%. In pregestational diabetic pregnancy sensitivity was 88.6%, specificity was 86.2 %, PPV was 88.6 %, NPV was 86.2%. In control healthy pregnancies the sensitivity was 70.6 %, specificity was 71.8%, PPV was 52.2%, NPV was 84.8 %.

Abstract: امراض الشرايين التاجية السبب الرئيسي لمعظم حالات العجز والوفاة في الدول المتقدمة. العمر, الجنس, السمنة, اختلال مستويات الدهون, التدخين, ارتفاع ضغط الدم, مرض السكر, الالتهابات, والاكسدة الضارة من اهم عوامل الخطورة الرئيسية للمرض. مجموعة من الدراسات اوحت ب | Coronary artery diseases are the most important causes of mortality and morbidity in many developing countries. Age, gender, obesity , lipid disturbance, smoking, hypertension, diabetes mellitus, inflammations and oxidative stress are considered as major risk factors of disease. Many of studies suggest that there is association between blood groups and risk factors of coronary artery diseases.Objective : The aims of study are to find if there is an association between blood groups and CADs and to study some of the causes that may be lead to this association. Also, it aims to determine the type of relation between some important factors such as, C - reactive protein (CRP), advanced glycation end products(AGEPs), and glutathione peroxidase - 3 (GPX - 3) with blood groups and coronary artery diseases. Materials & Methods : Ninety persons included in the study (60 as patients and 30 as healthy controls). Where the patients suffering from CAD, the controls are free from this diseases. Their ages ranged between 25 - 70 years old and they were divided into four groups according to the blood groups (A, B, AB, and O). This study is based on case control study done in Al - Sadder Teaching hospital (Cardiac Center) in Al - Najaf Al - Ashraf city from December 2012 - to October 2013. Some information were taken from each person in the study like, name, age, sex, address, weight and height. Finally and after getting permissions, the blood group was analyzed for each person in the study, then the sera were collected from those 90 persons and analyzed by using enzyme linked immunosorbent assay (ELISA) for CRP, AGEPs, and GPX - 3, meanwhile for lipids assay we used spectrophotometer. Results : The results of the study show that the blood group O( 33.7%) predominates in both studied groups (Patients and controls) followed by A (29.6%), B (27.4%), and AB (9%). There is no significant differences in the percentage of blood groups between patients and controls groups (P >0.05). Also, the results of the study show that the incidence of disease increase with age increases and in male (80%) more than female (20%). Also, the results show that only patients group has obese individuals and most obese were from blood group B(80%), followed by A(66.6%), O(60.8%), and AB(50%). The statistical analysis of the study shows that blood group AB among patients and blood group B among controls have a significant increasing (P<0.05) in the serum level of total cholesterol, and C - reactive protein (CRP). While, the results show that blood groups (B&AB) of patients have a significant increasing in the serum level of triglycerides. The blood group A among patients and blood group B among control show a significant increasing in the LDL cholesterol serum level, while blood groups (A& B) of patients have a significant reduction in the serum level of HDL cholesterol. Also, the study shows that blood group A of both patients and controls has a significant increasing in the serum level of advanced glycation end products (AGEPs), while the blood groups (A& B) of patients have a significant decreasing in the serum level of glutathione peroxidase - 3 (GPX3). Finally, the results of the study show a negative correlation (R= - ) between AGEPs and GPX3 in blood groups ( B&O) of both patients and controls group.Conclusions : Results of the present study show that the blood group O predominates in the studied groups in Al - Najaf Al - Ashraf city followed by A, B, and the last is AB. The incidence of CAD 2 to 4 time more common in male than female and incidence of CAD increase with age increases in both sex. The incidence of CAD 2 to 4 time more common in male than female and incidence of CAD increase with age increases in both sex. Also, There is a high percentage of subjects from blood groups (A, B, and AB) suffering from disturbance in the serum level of lipids and high level of CRP, which they were associated with atherosclerosis disease that was considered one of the most important leading cause of CAD.

Abstract: It has been proposed that the balance of Th1 and Th2 cells is critical in the development of Type 1 diabetes and much of the genetic susceptibility to IDDM maps to the MHC class II region, thus one approach to investigate the immunopathogenesis of diabetes is to study first degree relatives of affected individuals.A case - control study was performed on 120 persons, they divided into three group which are diabetic, siblings and control (40 persons in each group), who attended to Al Zahraa Teaching Hospital /Diabetic Center in Al Kut between the period from April; 2012 till April; 2013. OGTT performed on both diabetic siblings and control, results have showed that the means of OGTT is highly Significant (P value = 0.000) in both siblings and control groups, whereas there were no Significant differences in the Means of differences of OGTT in both tested groups (Siblings and Control), P value = 0.288, although the mean of differences of OGTT is higher in siblings group (25.3250) than that in control group (22.0750). Cytokines levels (IFN - gamma, IL - 2, IL - 4 and IL - 10) were determined among the study groups (type 1 diabetes, siblings and control) by ELISA method, results showed that the means of IFN - gamma and IL - 2 levels were highly Significant (P value = 0.012, 0.037 respectively) in type 1 diabetic group , in comparison to their corresponds among both siblings and control groups, whereas the mean of IL - 4 levels was non - significant (P value = 0.738) among the study groups (type 1 diabetes, siblings and control), in spite it was higher in control group (0.81936) than that in both type 1 diabetic patients and their sibling (0.74387, 0.77593 respectively).While in case of IL - 10 results showed that the mean was highly significant among control group (P value = 0.030) in comparison to its corresponds among both type 1 diabetic patient and their siblings. Distribution of HLA - DRB1 loci among the study groups (type 1 diabetic patients, siblings and control group) were performed using MR.SPOT ROBOTING system, results showed that the frequencies of HLA - DRB1*3,*4 {25 (69.4%)} among diabetic group were Significant in differences (P value = 0.002), in comparison to the corresponding frequencies among control group {11 (30.6%)}, in comparison to the frequencies of other HLA - DRB1 loci in both diabetic group and control group { 15 (34.1%), 29 (65.9%)} respectively.Meanwhile results showed that there were no Significant differences (P value = 0.116), in the frequencies of HLA - DRB1*3,*4 {25 (58.1%)} among diabetic group in comparison to the frequencies of HLA - DRB1*3,*4 {18 (41.9%)} among siblings group, in compare to the frequencies of other HLA - DRB1 loci among diabetic group and sibling group {15 (40.5%), 22 (59.5%)} respectively, also results have showed that there were no Significant (P value = 0.104), in the frequencies of HLA - DRB1*3,*4 {18 (62.1%)} among sibling group in compare to the frequencies of HLA - DRB1*3,*4 {11 (37.9%)} among control group, in compare to the frequencies of other HLA - DRB1 loci among sibling group and control group {22 (43.1%), 29 (56.9%)} respectively. In another part of this study we estimate the relation between means of HbA1c and their corresponding HLADRB1 Loci among the study groups, result have showed that there was a significant relation (P value = 0.010) between the Means of HbA1c and their corresponding HLA - DRB1*03 Locus among the study groups. In conclusion the higher Mean of differences of OGTT among Siblings group might reflect the potential of them to develop diabetes, also T1D is Th1 mediated disorder, while Th2 cytokines profile might play a protective role against the development of T1D,in addition the genetic predisposition of diabetic Siblings for development of diabetes since, both diabetic group and sibling group showing the highest frequencies of HLA - DRB1 *3,*4, in compare to Control group and finally HbA1c might have an inheriting pattern. In conclusion diabetic siblings more prone for development of diabetes in future.

Abstract: انخفاض الخصوبة مشكلة شائعة ولكن علاجها في بعض الاحيان غير كافي لعدم تشخيص الاسباب بالكامل. الحديد عنصر ناقل للاوكسجين ولذلك فهو محفز لحيوية كل الخلايا والانسجة في الجسم. نقص الحديد من اكثر مشاكل نقص الغذاء الشائعة في العالم. لذلك ربط الحديد مع الخصوبة يح | Subfertility is a common problem, but the treatment is sometimes inadequate because the causes are not fully diagnosed. Iron is essential for oxygen transport and therefore promotes health of all cells and tissues. Iron deficiency is the most common nutritional deficiency in the world. Therefore, the connection between iron and fertility need more explanation. Some researchers have suggested that iron may be important for ovulation as the egg has an increased demand for iron while it matures and women who do not get sufficient amounts of iron may suffer anovulation and possibly poor egg health, which can inhibit pregnancy at a rate 60% higher than those with sufficient iron stores in their blood. However women planning to become pregnant should test for serum ferritin level and accordingly if low they can use iron supplements because they may help them to prevent iron deficiency and also improve fertility. Vitamin C is essential for the uptake and absorption of iron. The objective of this study was to assess the iron status, vitamin C and some hormone levels in subfertile women. The sample of study consists of 106 women subdivided into two groups : first consist of 76 subfertile women were taken from the outpatient to fertility center in the gynecological and obstetrical teaching hospital in Kerbala city and from multiple gynecology/obstetrics privet clinics. Second consist of 30 fertile women (control and comparative) who obtained from outpatients and some relatives. The subfertile women subdivided into two subgroups according to the cause of subfertility in presented study : first group : ovarian dysfunction (OD) either due to polycystic ovary syndrom (PCOS) or due to other cause (OC) like anovulation, hyperprolactenemia, premature ovarian failure. Second group : unexplained (idiopathic). Also the subfertile women subdivided into two subgroups according to the type of subfertility : primary and secondary. All of them were at reproductive age (16 - 45) years and there BMI ranged between (20 - 45 kg/m2). The study was achieved throughout a period which extends from July 2012 - October 2013. The protocol of study summarized as following : At day 3±1of menstrual cycle (menstrual phase), all women underwent the measurement of concentrations for multiple hormones in the blood like luteinizing hormone, follicle stimulating hormone, estradiole, prolactine and Testosterone. In addition to iron status (serum iron, serum ferrtin and total iron binding capacity) and vitamin C also assessed. And at day 13 of menstrual cycle (near time of ovulation), all women underwent two investigations : first : the measurement of concentrations of luteinizing hormone, serum Leptin and antioxidants as vitamin C and glutathione. In addition to Iron status (serum iron, serum ferrtin and total iron binding capacity) and hemoglobin concentration also estimated. Second : estimation the size and the number of dominant follicles in both ovaries by ultrasonograghy. While at day 23±1 of menstrual cycle (secretary phase), all women underwent two investigations : first : estimation the concentration of serum progesterone to detect ovulation. Second : estimation the endometrial thickness by ultrasonograghy. The results of study shows : • A significant increase (P<0.05) in number of subfertile women with age group (16 - 25) years and there were highly significant decreases (P<0.001) in number of women with age 36 - 45 years for both primary and secondary subfertility. While no significant difference (p>0.05) in age group (26 - 35) years.• A significant increases (P<0.05) in body mass index for subfertile women due to polycystic ovary syndrome. Also a significant increase (P<0.05) in serum leptin for women with overweight and obese as compared with normal weight.• A significant increase (P<0.05) in serum ferritin level for polycystic ovary syndrome at day 13 of menstrual cycle. Also, a significant decreases (P<0.05) in number of polycystic ovary syndrome in those having serum ferritin lower than normal at day 13 of menstrual cycle.• A significant increase (P<0.05) in the number of subfertile women due to ovarian dysfunction other than polycystic ovary syndrome who having a lower serum level of vitamin C at day 3 of menstrual cycle. • A significant increase (P<0.05) in serum testosterone level in polycystic ovary syndrome group at day 3 of menstrual cycle. • A significant increase (P<0.05) in serum prolactine level in group of ovarian dysfunction due to other cause at day 3 of menstrual cycle. when serum ferritin level lower than or within normal value. • A significant decrease (P<0.05) in serum level of luteinizing hormone for group of ovarian dysfunction due to other cause at day 13 of menstrual cycle when serum ferritin less than normal but no significant differences (P>0.05) in serum luteinizing hormone when serum ferritin within normal value. • A significant decrease (P<0.05) in serum luteinizing hormone for group of ovarian dysfunction due to O.C when vitamin C within normal value at day 13 of menstrual cycle.• A highly significant decrease (p<0.001) in endometrial thickness for all subfertile group at day 23 of menstrual cycle.• No significant difference (P>0.05) in serum levels of follicle stimulating hormone, estradiole and glutathione as compared with other parameters in fertile and subfertile women.It was concluded that the decrease in serum ferritin and vitamin C levels in the blood may be associated directly or indirectly with subfertility caused by ovarian dysfunction.

Angiotensin II may contribute to reperfusion injury by increasing oxidative stress and inflammatory factors. Ang II exerts most of its effects via AT1Rs. Objective : This study was undertaken to investigate the potential role of Telmisartan and AT1 - AB in amelioration of myocardial I/R injury induced by ligation of coronary artery in mouse model. Materials & method : Adult male Swiss - albino mice were randomized into 6 equal groups. Group (1) sham group : Mice underwent the same anesthetic and surgical procedure as the active control group except ligation of LAD coronary artery.Group( 2) active control group : Mice were subjected to regional ischemia for 30 min by ligation of LAD coronary artery and reperfusion for 2 hours.Group( 3) control vehicle group (1) : Mice in this group injected with DMSO (vehicle for Telmisartan ) via IP route & underwent Myocardial ischemia for 30 minutes by ligation of (LAD) coronary artery & reperfusion for 2 hr. Group( 4) control vehicle group (2) : Mice injected with D.W ( vehicle for AT1 - AB) via IV route & underwent Myocardial ischemia for 30 minutes by ligation of (LAD) coronary artery & reperfusion fore 2 hr. Group (5)Telmisartan treated group : Mice pretreated with Telmisartan 0.5mg/kg i.p 30 minutes before ligation of LAD coronary artery. Group(6) AT 1 - AB treated group : Mice pretreated with AT 1 - AB (1Mcg/gm.) of body weight via IV route 30 minutes before ligation of LAD coronary artery. Results : Compared with the sham group, Levels of TNF - ? & IL - 1?, IL - 6,caspase 3 and plasma level of cardiac troponin I increased in control group (p<0.001).Levels of Bcl2 decreased in control group(p<0.001). Histologically ,All mice in control group showed a significant (p<0.001) cardiac injury. Both Telmisartan and AT1 receptor antibody significantly counteract the increase in myocardium level of TNF - ?, IL - 1B,IL - 6,caspase 3 ,plasma cTnI (P < 0.001). Furthermore, the Telmisartan and AT1 receptor antibody significantly increased in myocardium level of Bcl2. Histological analysis revealed that both Telmisartan and AT1 receptor antibody markedly reduced (P < 0.001) the severity of cardiac injury in the mice underwent LAD ligation procedure. Conclusion : The results of the present study reveal that Telmisartan and AT1 receptor antibody ameliorate myocardial I/R injury in Mice via interfering with inflammatory reactions & apoptosis which induced by I/R injury.

Abstract: يسجل الرسم الكهربائي للدماغ الفعالية الكهربائية الذاتية المتولدة في قشرة الدماغ. اشارة الرسم الكهربائي للدماغ هي قياس للتيارات المتحركة في قشرة الدماغ. عندما تحفز خلايا الدماغ (العصيبات), يتم توليد التيار الارتباطي في التشجرات العصبية للخلايا. يولد هذا ال | Electroencephalography (EEG) records the spontaneous electrical activity generated in the cerebral cortex. When brain cells (neurons) are active, synaptic currents are produced within their dendrites and this current generates an electrical field over the scalp. The EEG waves measure this current that flow during synaptic excitations of pyramidal neurons' dendrites. Preeclampsia is a disease of pregnancy characterized by a blood pressure of 140/90 mmHg or more on two separate occasions after the 20th gestational week in a previously normotensive woman. This is accompanied by significant proteinuria (>300 mg in 24 hours) and is associated with endothelial cell damage. The markers of endothelial activation or inflammation have been blamed to play an active role in preeclampsia (Sibai et al., 2005). This study included 97 pregnant with a confirmed diagnosis of preeclampsia as a patient group with a gestational age ranging between 20 - 38 weeks. They are divided into three subgroups according to their gestational age (20 - 26 wk, 27 - 32 wk and 33 - 38 wk) and the mean of their age was 29.34±4.82, 30.14±5.33 and 32.54±6.22 years respectively. In addition, 72 women with normal pregnancy have been included as control group. These were also subdivided into three subgroups just like that of the patients and their age matches them too. Participants belong to both patient and control groups had underwent same procedure, examinations and tests like EEG and serological tests for Intracellular Adhesion Molecule 1 (ICAM I), interleukin - 6 (IL6) and C - reactive protein (CRP), in parallel. Results showed that there were statistically significant increased levels (P < 0.05) of ICAMI, IL - 6 and CRP values between patient and control groups and between the patient with mild and those with severe preeclampsia in all tested gestational age subgroups. This supports the hypothesis stating a role of cytokines and inflammatory biomarkers in the mechanism underlying preeclampsia. Moreover, and at all gestational age subgroups, the ICAMI, CRP and IL - 6 values were higher in patients with severe disease when compared with those having milkd disease. This strengthens more the relation of these biomarkers with the progression of preeclampsia. There were abnormal EEG changes in about 52 % of the patients with preeclampsia and these changes were reported in all gestational age subgroups and were in the form of spikes, polyspikes, slow sharp waves. This shows that preeclamptic females are prone to some excessive brain activities that may put them in danger of abnormal brain function. Furthermore, these EEG abnormalities were related to the severity of the preeclampsia as they were recorded in severe cases more and at all gestational age subgroups. Also there were statistically significant elevation regarding ICAMI (at the second and third gestational age subgroups), IL - 6 values (at the second gestational age subgroup) and CRP (at all gestational age subgroups) among patients with and without abnormal EEG changes. This suggests a strong relation between these inflammatory biomarkers with the occurrence of abnormal EEG changes in preeclamptic females. In conclusion, an inflammatory process is blamed to be the underlying mechanism of preeclampsia as proved by the elevated levels biomarkers in these patients. Both the abnormally elevated biomarkers and the abnormal EEG changes occur in preeclamptic patient in different gestational ages above 20 weeks and occur in different disease severity.

The rate of toxoplasmosis and of subclinical infected infants at birth with the risk of late manifestation is still unclear, whereas such data are fairly well - known for Rubella , Cytomegalovirus and Herpes virus. The respective major diagnostic issues in pregnancy, the laboratory diagnosis, and its rational use in combination with clinical information are presented , also the value of passive prophylaxis, therapy, and prenatal diagnosis as well as the possible management for diminishing the infection problems in pregnancy.Aims of study : The study was aimed to evaluate the ELISA result for Toxoplasma, rubella, cytomegalovirus (CMV) and Herpes virus (TORCH) IgM and IgG and compare the results of the ELISA with RT - PCR to arbitrate discordant results.Methodology : The present study was carried out on 57 pregnant women, all of them had with bad obstetric history (BOH) of abortion twice or more. Patients were between 15 - 40 years of age, and they were attending Al - Zahraa Maternity and pediatric Teaching Hospital, Al - Hakeem Hospital and some private clinics, in AL - Najaf province during the period from May 2012 till May 2013. Serological evaluation for TORCH infections was carried out by using IgM and IgG Enzyme Linked Immunosorbent Assay (ELISA ) method and molecular technique ( DNA; RNA - RT - PCR). Each blood sample was divided into two part , one part plane tube for separation of serum that were screened for the presence IgM and IgG antibodies against Toxoplasma gondii ,Cytomegalovirus Rubella virus and Herpes simplex virus by using (ELISA test ).The tests were performed according to manufactures instruction.The other part (blood )EDTA tube was used for DNA 0f detection Toxoplasma , CMV and Herpes simplex virus , while RNA extraction of Rubella virus.The blood and serum sample were stored in refrigerator (2 - 8C?) before the analysis.The extracted DNA and RNA were stored at - 20C? till used within 24 hours. All ELISA Results samples were compared with Real - Time PCR result. Statistical analysis : Statistical program SPSS version (20.0) was used to study the significant difference between tests in each type of antibody (IgM and IgG). (X2 - test) was used after detection of normal distribution to the data and appropriate P<0.001 consider significant. Results : Both IgM / IgG was Seropositive to T. Gondii , Rubella , CMV and HSV - 2 which were 49.12/80.70%, 21.05/49.12% , 45.61/70.18% and 1.21/36.20% respectively. Samples were seropositive to IgM and results were retested by RT - PCR method. Maximum number of IgM /IgG seropositive cases of aborted women was 19(32.75%)/57 that associated with Toxoplasma ,Rubella and CMV infection by RT - PCR ( 10(17.54%), 6( 10.53%) and 3(5.26%) respectively ). The ELISA TORCH IgM and IgG assays provided results comparable to RT - PCR indicated significant differences among Toxoplasma and viral infection. The ELISA TORCH infection IgM and IgG assays showed a lower specificity with for Toxoplasma IgM (p=0.001), poor for CMV IgM and moderate for Rubella virus IgM.Conclusion : The accurate diagnosis of TORCH infection should be done by molecular method.

Abstract: في هذه الدراسة العرضية, تم اختيار 140 شخصا بصورة عشوائية, من بينهم 90 كان مصابا بالسكري والباقون كانوا سليمين ,لدراسة تاثير ارتداء طقم الاسنان الكلي والجزئي من قبل مرضى السكري على فحوصات كفاءة الرئتين وبالتحديد, , السعة الحيوية القسرية (FVC)و الحجم الزفير | In this cross sectional study, a total number of 140 subjects selected randomly, 90 of them were diabetic and the remaining were normal, to study the effect of complete and partial dentures wearing by diabetic patients on pulmonary function test particularly peak expiratory flow rate (PEFR), forced expiratory volume in the first second (FEV1), forced expiratory volume ratio (FEV1/FVC) ratio (FEV1%), forced vital capacity (FVC), and also the retropharyngeal space (RPS), the level of Endothelial selectin (E - selectin) and the level of Vascular Cell Adhesion Molecule - 1(VCAM - 1)was also compared, in this study, between the diabetic and the normal subjects.The results indicate that the spirolab III was accurate and reproducible and can be used in all related studies.The effect of wearing of complete and partial dentures by diabetic patients on FVC, FEV1, PEFR and also the degree of alteration of the RPS were measured.1) The results of the study shows a significant increase in values of FEV1, FEV1%, PEFR and retropharyngeal space (RPS) (p<0.05), while there was no significant change in the value of FVC after the replacement of complete denture.2) No statistically significant differences in the values of FVC, FEV1, FEV1%, PEFR and retropharyngeal space (RPS) was observed after replacement of partial denture without free end extension3) There was a significant increase in values of FEV1, FEV1%, PEFR and retropharyngeal space (RPS) (p<0.05), never the less there was no significant change in the value of FVC after the replacement partial denture with unilateral free end extension.4) There was a significant increase in values of FEV1, FEV1%, PEFR and retropharyngeal space (RPS) (p<0.05), However there was no significant change in the value of FVC after the replacement partial denture with bilateral free end extension5) The results showed that in poor and good control diabetic patients there was a significant decrease in the values of FEV1, PEFR, FEV1%and RPS after the removal of all types of dentures(p<0.05), while no significant change in FVC.6) Statistical significant increase in Serum E - selectin and VCAM - 1 level was found in diabetic patients when compared to that of the normal subjects (p<0.05).7) No statistical significant difference between serum E - selectin and VCAM - 1 level in diabetic patients after and before denture placement (p>0.05). The cause of the significant change in the values of FEV1, FEV1%, PEFR and retropharyngeal space (RPS) in case of complete and partial denture with free end extension replacement may be due to pressing of the retropharyngeal space bilaterally and unilaterally by the complete and partial denture and the FVC was not significantly changed because it may not be affected by denture support, while the elevated Serum E - selectin and VCAM - 1 level might indicate endothelial activation and inflammation.In conclusion we can conclude that 1. The spirolabIII used in this study is an accurate and reproducible device and can be used in the assessment of lung function test.2. Values of FEV1, FEV1%, PEFR and retropharyngeal space (RPS) where significantly higher after the replacement of complete denture and partial denture with bilateral and unilateral free end extension in diabetic patients (p<0.05), while there was no significant change in the value of FVC.3. No statistically significant differences in the values of FVC, FEV1, FEV1%, PEFR and retropharyngeal space (RPS) was observed after partial denture without free end extension has been replaced in diabetic patients.6. In poor and good control diabetic patients there was no significant change in the value of FVC, while the values of FEV1, PEFR, FEV1%and RPS where significantly decrease after the removal of all types of dentures.8. Statistical significant increase in Serum E - selectin and VCAM - 1 level was found in diabetic patients when compared to that of the normal subjects.9. The results for serum level of E - selectin and VCAM - 1 shows no significant difference diabetic patients after the placement of all types of dentures (p>0.05).
