It also included the preparation and detection of two hybrid nano compounds, one of them from the disinfectant chlorhexidine and the other from the tannic acid. The inhibitory activity of the nano disinfectant was assessed against the isolated bacteria in this study also, the antioxidant activity of the hybrid nano tannic acid was identified and the results showed the following : 1 - As a total 32 samples were taken from burned patients hospitalized in the burning ward Imam Al - Hussien medical city in Sacred Karbalaa governate. It had been obtained 8 isolates (34.78) % from Pseudomonas spp., 7 of them were Pseudomonas aeruginosa and one was P. oryzihabitans , 4 isolates (17.39) % were Acinetobacter baumannii, 4 isolates (17.39) % were Klebsiella pneumoniae, and one isolate (4.34) % of Proteus mirabilis, Escherichia coli, Serratia liquefaciens and Chryzeobacterium meningosepticum and two isolates (8.69) % of Staphylococcus aureus in addition to one isolate (4.43) % from Candida guilliermondii yeast.2 - Chlorhexidine disinfectant and tannic acid were used in preparation of the two hybrid nano compounds after intercalating each of them on layers of double hydroxide (Mg/Al - LDH). FT - IR spectrum studies has shown the appearance of specific chemical groups and the disappearance of others while the spectrum of x - ray(XRD) has shown the appearance of new levels of diffraction in the spectrum of the hybrid nano disinfectant Mg/Al - CHX - LDH and the spectrum of the hybrid nano tannic acid Mg/Al - TA - LDH as compared to the spectrum of the Mg/Al - LDH, which indicate that the two prepared compounds under study is a nano hybrid compounds. Results of the scanning electronic microscope has shown, the change in the shape of the surface of the nanohybrid compounds that prepared above as compared to the layer of double hydroxide. It turns out from the results of the examination with the use of Atomic Force Microscope (AFM), that the diameter of the particles of hybrid nano disinfectant and hybrid nano tannic acid were (121.66 and 77.70) nm, respectively. 3 - The inhibitory activity of the hybrid nano disinfectant Mg/Al - CHX - LDH and the free disinfectant (Free CHX) has been studied and the results revealed followings : a. The hybrid nano disinfectant has the highest inhibitory activity against the two bacterial isolates P. aeruginosa (11 and 23 - A) with an inhibition diameter of 24 mm for each, while the inhibition diameter for the free disinfectant was 23.5 mm against the isolate P. aeruginosa 4 - C.b. The hybrid nano disinfectant showed the highest inhibitory activity against the two isolates A. baumannii (16 - A and 31 - A) with an inhibition diameter of 18 mm for each, while the highest inhibition activity for the free disinfectant was against the isolate A. baumannii 22 - B with an inhibition diameter of 19.5 mm.c. The hybrid nano disinfectant showed the highest inhibitory activity against the isolate K. pneumoniae (16 - B) with an inhibition diameter of 24.5 mm, while the highest inhibition activity for the free disinfectant was against the isolate K. pneumoniae 15 - B with an inhibition diameter of 24.5 mm also.d. The highest inhibition activity for the hybrid nanoic disinfectant against each of bacteria P. mirabilis and E. coli with an inhibition diameter of 23.5 mm, while the highest inhibitory activity for the free disinfectant was against the bacteria E. coli with an inhibition diameter of 24.5 mm, while the bacteria C. meningosepticum was the least affected among the other types of the isolated bacteria with an inhibition diameter of 8 mm and it was resistance to the hybrid nano disinfectant.e. The highest inhibition activity for the hybrid nano chlorhexidine was against the isolate S. aureus 21 with an inhibition diameter of 28.5 mm, while the highest inhibition activity for the free chlorhexidine was against the isolate S. aureus 22 - A with aninhibition diameter of 31.5 mm.f. The inhibitory activity of both the hybrid nano and the free disinfectant against C. guilliermondii yeast was closely to each other with an inhibition diameter of (28 and 29) mm, respectively.4. The study of antioxidant activity confirmed the following : a. Using free radical scavenging method, the IC50(Half maximal inhibitory concentration) value against ABTS free radical were at 10 µg /ml for free tannic acid while it was at 125 µg /ml for the hybrid nano tannic acid Mg/Al - TA - LDH.b. Measurement of ferric ion reducing power revealed that free tannic acid had reducing power greater than that of the hybrid nano tannic acid

One hundred samples were collected from people who suspected to infect with fungal skin disease from patients coming to Al - Diwaniya teaching hospital from beginning of October 2013 till the end of May 2014. These samples from (skin, hair and nail). All samples that taken from patient were subjected to direct examinations by using wet touch of (KOH 10%) solution. At the same time the samples were grew on sabroud media to determine the type of fungal skin diseases of human. The direct examination shows positive results of 72 samples which represent 72% while for laboratory growth results, its shows 65 samples with positive results 65%. There are three types of Trichophyton fungus had been isolated which are T.rubrum 28 isolates, T.mentagrophytes 16 isolates and T.schoenleinii 4 isolates and there was one type of genus Microsporum which is M.canis 24 isolates. The results show that Tinea corporis infection is the common and its more among females than males where it is 26.39% and 13.89% respectively, then Tinea capitis which is 19.4% in males which is higher than in females which represents 13.89% while Tinea unguium was in females more than males which was in females 16.67% while in males 9.72%. The percentage of fungal skin infection was differ according to the location where the number of infections in the rural area for all types of Tinea were more than the number of infection in the urban area where the number of infected people with Tinea corporis was 18 which represent 25% while in the urban the number was 11 which represent 18.28% while the number of infected people with Tinea capitis in the rural area were 16 which represent 22.22% and the infected in the urban were 8 which represent 11.11%. While Tinea unguium the number of infected people in the rural 10 which represent 13.89% and in the urban 9 people which represent 12.5%. The diagnosis of isolated fungi depended on phenotype of fungal growth and microscopic examination, in addition to special tests for diagnosing skin fungal infections. Also the PCR was used for diagnosis and the work had been completed by using genotypic tree for fine diagnosis and detection the fungal species. The result were send to the genes bank site to be sure about the fungus type through comparison with the registered fungi in this site and by using MEGA6 program for genetic tree analysis of type (unweighted pair group method with arithmetic mean). The results of analysis shows clear converge of local Trichophyton spp. Isolates with Trichophyton rubrum in comparison with other types that appears in the genetic tree analysis while Microsporium diagnosed through genetic tree analysis of type (up GMA tree) and the result of analysis shows clear converge of local Microsporium spp. Isolates with Microsporium canis compared with other types of genetic tree analysis. The effect of silver nanoparticles that is used against growth of T.rubrum, T.mentagrophytes and M.canis. The results show that all the concentrations used were effective in stopping of growth of T.mentagrophytes when deal with the standard measure when dealt with concentration of 4 mg/l the more effective in stopping of radiating growth of the fungus. Regarding the fungus T.rubrum the concentrations of 4 mg/l more effective in stopping of growth while there was no difference for 1mg/liter concentration. Regarding the fungus M.canis, the mentioned concentrations had large effect on fungal colonization growth compared with the standard and this fungus more than other fungi affected by nano silver ions

Bacteriological culture identified fifty (80.33%) isolates as E. coli depending on cultural and biochemical characteristics as well as Api and Vitek 2 automated systems. However, 82% of isolates developed ? - hemolysis on blood agar plates.Susceptibility of all isolates against seven commonly prescribed antibiotics were investigated and 96, 82, 84, 92, 92, and 56%. of isolates were resistant to ampicillin, ampicillin/sulbactam, amoxicillin/clavulanic acid, cefalothin, imipenem, and meropenem, ceftazidime, respectively.Concomitantly, ? - lactamase production was detected phenotypically by disk replacement method. The results showed that 82% of all isolates have the ability to produce ? - lactamase. Interestingly, correlation coefficient between ? - lactamase and hemolysin production was 0.99.Using microtiter plate method, all E. coli isolates were tested for their ability to form biofilm. The results revealed that 36, 54, and 10% of isolates formed biofilm with variable thickness; weak, moderate, and strong, respectively.Alongside with previous findings, blaCTX - M - 2, blaVIM, blaTEM, and blaPER were identified in 18, 12, 10, and 4, respectively. Nevertheless, none of blaOXA - 1, blaOXA - 4, blaOXA - 30, blaIMP, blaCTX - M - 1, blaCTX - M - 9, blaKPC, and blaSHV. The isolate number 11 harboured the highest number of genes (blaTEM, blaVIM, and blaPER) among all tested isolates. Twelve albino mice was divided randomly into four groups comprising A through D injected with ceftazidime at sub MIC, E. coli 11, E. coli 11 with ceftazidime solution, and standard strain, respectively.Histopathological sections did not show any changes in respeuct to group A. however, group C suffered signs of infection less than those appeared in group B sections. Simultaneously, group D suffered intense histpathological changes more than other groups infected with resistant isolate.

From 61 patients by two samples per patient, also were collected 228 samples of stool from the laboratory of the Department of parasites by two samples of 114 patients for the period from January 2014 to January 2015. Where shown on biopsy results which were subject to examination by the rapid urease test (RUT) the presence of 60 (98.4%) cases, while there were 23 (37.7%) case of those bacteria being positive related to biopsy was not significant differences between the two tests performed. When the distribution of test results (RUT) and culture according to age group, it appear that the highest percentage of infection was in 50 - 41 age group that which showed the highest percentage on examination (RUT) of the number of infected at 16 (26.23%) cases, either in the culture technique number of infected at 9 (14.75%) cases. But when the results of each of the examination (RUT) and culture were distribution according to the sex of the patient's infection was the higher in the females than males reaching males 28 (45.90%) cases in females of 32 (52.46%) cases for examination (RUT). No significant differences appear between the sexes in terms of infected. While the males in 8 (13.11%) and in the case of females was 15 (24.59%) case for the culture technique it did not show significant differences between the sexes in terms of the patients. While taking stool samples to check the stool antigens, it was found that there are 76 (66.7%) cases diagnosed while the technology for the polymerase chain reaction gene cagA to 49 (43%) cases have significant differences between the tests performed. When distribution the results of each of the stool antigens and polymerase chain reaction technique by age group category the highest infected was in 46 - 55 the age group with the number of 23 (20.18%) people case for screening stool antigens. The test results of the technology polymerase chain reaction showed that highest rate of infection was in the 35 - 26 age group where the number of patients was at 15 (13.16%) case.The results of the stool antigens examination also showed that the infection rate among males was higher than females, 39 males (34.21%) and in the case of females has reached the number of 37 cases (32.46%) casesThat did not show significant differences between the sexes patient. The technical results of the polymerase chain reaction by sex has been the injury was higher in females than males reaching 22 in males (19.30%) cases, while in females was 27 (23.68%) cases did not show significant differences between the sexes in terms of the infected. The results of the study conclude that (RUT) and stool antigen test is the fastest in the detection of infection from the bacteria H. pylori and then comes beyond culture technique for biopsy sample and then polymerase chain reaction for stool samples

المستخلص: للفترة من اذار 2014 الى اذار 2015 تم جمع 1300 عينة سريرية مختلفة (عينات ادرار ومسحات جروح وحروق وعينات دم ومسحات من الفم والاذن والعيون بالاضافة لعينات البراز والقشع) من اثنين من مستشفيات محافظة بابل (مستشفى الحلة التعليمي ومستشفى بابل التعليمي للنسائية و| During the period between March 2014 and March 2015, a total of 1300 clinical specimens (urine, wounds, burns, blood, throat, ear, eye, stool, and sputum) were collected from two hospitals in Babylon province; Al - Hillah Teaching Hospital, and Babylon Hospital for Maternity and Pediatric. All specimens were cultured and 10 Acinetobacter baumannii isolates were obtained from clinical specimens in a percentage of (0.76%) distributed in blood 1 (0.6%), urine 2 (1%), wound infection 1 (0.75%), burn 5 (0.85%) and throat 1 (2%). This study was conducted to determine the occurrence of carbapenem resistant A. baumannii isolates obtained from Hillah hospitals. Isolates were identified according to API20E system and further confirmed using PCR technique. Antibiotics susceptibility was assayed by using disks diffusion method according to CLSI recommendations. All isolates revealed positive results with rapid iodometric test indicting the ability of beta lactamase production. Phenotypic detection of carbapenemase production was performed using the imipenem - EDTA disk and modified Hodeg's test (MHT). Then isolates were subjected to monoplex PCR targeting blaOXA - 51, blaOXA - 23, blaOXA - 24, blaOXA - 58, blaIMP, blaSIM blaNDM - 1, blaNDM - 2 and blaVIM genes, as well as, efflux pumps genes. One of the identified isolates (10%) was found to be imipenem, meropenem and ertapenem resistant, this isolate gave positive result with the imipenem - EDTA disk and (60%) of isolates were positive to MHT. PCR experiments showed ; all isolates were harbored blaOXA - 51 gene, four (40%) isolates were harbored blaOXA - 23 gene, three (30%) isolates were harbored blaOXA - 24 gene, four (40%) isolates were harbored blaOXA - 58 gene, five (50%) isolates were harbored blaIMP gene, six (60%) isolates were harbored blaSIM gene, two (20%) isolates were harbored blaNDM - 1 gene, four (40%) isolates were harbored blaNDM - 2 gene, while none of these isolates harbored blaVIM gene. The present findings suggest that emergence of (OXA - 23, OXA - 24, OXA - 58, IMP, SIM, NDM - 1, NDM - 2) carbapenemase producing A. baumannii clinical isolates in Hillah City hospitals. Also there are indicative appearance of efflux pump genes ; (50%) for Ade - A and Ade - B each other, (40%) for Ade - C, (80%) for all of Ade - R and Ade - S, (100%) for all of Ade - I and Ade - J, and (50%) for Ade - Y. All isolates of A. baumannii appear as MDR, while only one appear to be as PDR. The trans - mobility of resistant genes was examined by trans - conjugation experiment ; the results indicated that only blaIMP and blaOXA - 23 genes were transferred horizontally in the current study. In attempting to investigate any blaNDM gene variation the results showed some different than NCBI - Blast A. baumannii blaNDM - 1 and blaNDM - 2 it may as a unique genotyping.These results revealed that carbapenemase producing A. baumannii were detected in both phenotypic and genotypic methods (PCR). This underlies the importance of their accurate identifications and reporting to prevent the emergence of complete resistance to the most potent drugs against A. baumannii in Babylon province.

The result of laboratory culture were positive in 67 samples. Depending on their cultural, morphological and biochemical characterization of bacterial isolates : (37.31%) of them were identified as Streptococcus pyogenes bacteria and the diagnosis is confirmed by the use of Remel Rapid STR System. Whereas (34.33%) belong to S.parasanguinis, (11.94%) S.mitis, (11.94%) S.oralis and (4.48%) S.thoraltensis were identification of them are confirmed by using Vitek - 2 System also. As well as Sensitivity test for S.pyogenes cultures for some of the antibiotics done and the results revealed that all cultures were sensitive to tetracycline and chloramphenicol drugs 100%, while it was different in their sensitivity for other drugs. According to age (2 - 13) years revealed the highest percentage of infection for both male and female, however the percentage of acute and chronic tonsillitis was higher in males than females. In this study, during investigation of the antagonist action of lactic acid bacterial isolates against these pathogenic bacteria, results revealed that the method of L.acidophilus discs gave a high inhibition zones with a diameter of 11.3 mm, while L.fermentum discs yielded a high inhibition zones with a diameter of 7 mm 24 hrs following incubation in comparison with well diffusion method by using suspension of L.acidophilus produced a high inhibition zones with a diameter 7.25 mm 48 hrs after incubation. L.fermentum suspension produced a high inhibition zones with 10 mm diameter 24 hrs following incubation. Also the study included measurement of the inhibition activity for bacteriocins produced by L.acidophilus bacteria against the pathogenic bacteria S.pyogenes on nutrient agar by well diffusion method in which results revealed stability of the bacteriocins effects under different PH (4, 5, 6) with percent (100, 60, 50)% respectively for 24 hrs at higher stability and the highest stability of bacteriocins during PH was 4 with percent 100%, while it lost a lot of its activity with acidic PH less than 2 and basal pH more than 8. During the study the effect of Nacl, Kcl and MgSo4 with different concentrations (1 - 5%) with constant inhibitory effect for bacteriocins produced by L.acidophilus against pathogenic S.pyogenes, The result revealed that Nacl had little effect in inhibition zone with 1&2% concentrations. The salt MgSo4 and Kcl showed reduction in the inhibitory activity with 1, 2, 3% concentration, however the higher concentration of salt caused great reduction as 5% concentration led to loss of inhibitory activity for bacteriocins completely.Also this study showed light on the inhibitory effect of probiotics suspensions against the adhesion property of S.pyogenes after treated with L.acidophilus and L.fermentum.where the Result shown that L.acidophilus inhibit the adhesion of S.pyogenes with percent 68.92% either L.fermentum inhibit the adhesion of this pathogenic bacteria to epithelial cell with percent 30.28%. The study is consisted of showed the inhibitory action for suspensions of L.acidophilus and L.fermentum on biofilm formation by S.pyogenes, it was noticed the action of L.acidophilus in the side more than from the action of L.fermentum. During the study of the effect of suspension and filter of L.acidophilus and L.fermentum on the production of Hemolysin enzyme by S.pyogenes, it was noticed that the ability of suspension belong to L.acidophilus and L.fermentum to reduce the diameter of hemolysis zone which was beta type more than the ability of filter L.acidophilus and L.fermentum to reduce of the hemolysis zone which was beta type.

Only 51(31.875 %) Staph. epidermidis isolates were obtained during a period from September 2014 to January 2015, depending on some biochemical tests and VITEK2 system. The Staph. epidermidis was given (gram stain, catalase , urase) positive, (coagulase, manital fermentation, oxidase, motility) negative, non haemolytic to human blood with some exception, most of the strain were able to produce biofilm, and (100%), (64.70%), (74.50%) resistant to penicillin G, ampicillin, and amoxicillin respectively. The Staphylococcus species identified during study were 44 (27.5%) isolates of Staph. aureus, 5 (3.125 %) Staph. haemolyticus, 4 (2.5 %) Staph. saprophyticus, 8 (4%) isolates other Staphylococcus spp. such as Staph. hominis ssp. hominis, Staph. capatis, Staph. xylose, Staph. simulanus, Staph. lentus, and 48 (30 %) from unknown genera. To isolate bacterioghages from sewage water, several sewage water samples were assayed using plaque assay of double agar overlay as a source of Staph. epidermidis phages. The bacteriophages were described depending on plaques size and shapes, phage 1 was the most predominant and frequent in the bacterial lawn and able to infect other S. species such as S. aureus. It has been selected to study it is titer, latent, rise period, and burst size were calculated. The effect of temperature, pH , and NaCl ions on it is original titer were studied.The results revealed a gradual decreasing in the phage titer with increasing dilution number. Latent period extended to (30 minutes) , while rise period was started with (40 minutes) extending to (60 minutes) , burst size was 2.346. Each temperature at several incubation periods , pH , and NaCl ions was significantly varied depending on phage titer. The optimum temperature was 40 ° C, while the 80 ° C was represented the inhibitor temperature. L.S.D. at level (0.05) for interaction was 39.552. The pH 6.5 - 7.5 represented the optimal pH for the best phage activity while the phage titer beginning to declining in above and below this range of optimal pH, L.S.D. at level 0.05 was 17.898 , the optimum NaCl ions concentrations were (0.1 M and 0.25 M), while the titer was significantly decreased with increasing the NaCl ion concentration in the culture solution, the L.S.D. at level 0.05 was (10.696). In conclusion of this study found that Phage1 was considered as predominant phage because of their ability to infect other Staphylococci species such as Staph. aureus.

المستخلص: “The current research dealed with fourteen taxa belonging to the genus Ranunculus L., Family Ranunculaceae that grown in Iraq. The study included the gross general morphological and micromorphological characters, the Pollen grains also were studied and the chemical compounds (Flavonoids), Ecological and geographical distribution and taxonomic treatment have been done. Also botanical key was puted to separate the Taxa”.“General survey for the Phytogeographical districts where the taxa spread in, and the result was a large crowds of samples, and new locations of taxa distribution were recorded. The specimens in the Iraqi herbaria were studied after ensuring that it was correctly identified”. “Comparative morphological study was undertaken to all plants parts of taxa including the roots, leaves, stipules, flowering parts and fruiting parts. Charts, diagrams, tables were drawn and accompanying with natural images for different morphological characteristics, as well as the field images that are important for the study. This study showed that all the taxa of the genus were herbs that are annual or perennial. There was agreat important for the roots, stems and there Indumentum, the presence orabsence of stipules, shape and size and margin of basal leaves and cauline leaves and leafy bract, the shape of sepals and their numbers and their Indumentum, the numbers and shape of Petals and their colors, the number of Stamens and the colors of Anthers, the shape of ovary and their indumentum, presence or absence of style as it was very useful for the taxonomic identification and separation of the studied taxa. As well as the fruiting parts including the length of fruiting peduncle, the fruiting receptacle, the fruiting head and its shapes and their dimensions, the number of Achene Fruitlets and their sizes, colors and Beak shape. Also the surface configuration of the fruitlets Surface has been studied by (SEM) as it wae either hairy or tuberculate - hairy or Transversely rugose or muricate or reticulate or reticulate - minutly rugose or granular or granular - hairy or granular - hairy tuberculate or spinulose”.“The study of the micro - morphological characters of hairs, leaves epidermal cells and the stomatal complex, have a taxonomic importance of supporting the morphological characters in separation and identification of the genus taxa”.“The study show that the pollen grains have a taxonomic importance because of their difference in shape, dimensions, the wall thickness and their ornamentation. It was either apolar which was spheroidal and pantoporate, or isopolar which has different shapes in the equatorial view it was spheroidal, subprolate and oblate - spheroidal, it was either 3 - colpate, 4 - colpate or 5 - colpat.the colpate where either zonocolpate or syncolpate in the form of parasyncolpate. The ornamentation were verucate, echinateand scabrate”. “The chemical study also has an importance in separation of the genus taxa, six flavonoid compounds were diagnosed by using” HPLC wich are Kaempferol, Vitexin, Orientin, Quercetin, Iso - vitexin and Iso - orientin. According to the presence or absence of those structures cluster analysis where done for the results of the flavonoid compounds and the taxa where divided into groups that reveal the chemical relationships between them.dendogram where performed which also show the chemical relationships between the taxa by using UPGMA method and NTSYS program issue 21. the study shows that the presence and distribution of those compounds vary according to the variation in the plant distribution the study shows that some of the taxa have “the same compounds which enhance its belonging to the Ranunculus genus”. “Through field surveys and information installed on the herbarium samples, the taxa where distributed on their growth areas, and maps have been drawn for taxa distribution in the Iraqi natural geographical. Most of the taxa were distributed in N. and N.E of Iraq regions districts especially in MAM, MSU, MRO, and FBF districts. We notice that MSU district has a great number of the plants under the study as we found there are all the taxa accept one”. This study helps to detect distribution areas for some taxa that have been not mentioned in the Iraqi flora or other records which are R.kotschyi and R.trichophyllus var.trichophyllus. Also the study records distribution for the new species R.chius in MAM district which hasn't been mentioned in the Iraqi flora in this district before. Finally all the taxa were classified and the botanical key was done to separate them.

المستخلص: هناك مفهوم متنام يشير الى زيادة انتشار البدانة بين مرضى القلب التاجية Coronary heart disease (CHD), مما له الاثر الكبير في نشوء المرض ومضاعفاته, اذ يشابه عمل الخلية الدهنية adipocyteعضو الافراز الداخلي endocrine organ.ولمعرفة العلاقة بين البدانة وامراض | There is a growing concept that refers to the increased prevalence of obesity among patients with coronary heart disease. This has significant impact on the emergence of the disease and its complications as the work of the adipocyte resembles the work of the endocrine organ. This study comes to know the relationship between obesity and heart disease. To accomplish this, about 5cm3 of venous blood has been collected from 240 patients of coronary heart disease who are admitted to the resuscitation unit in Baquba Teaching hospital for the period 1st of December 2014 to1st of January 2015. The range of the patients' age is between 22 - 90 years old. The sample has been divided into three groups in accordance with body mass index and according to the classification of the American Institute. These groups are : natural weight from 18.5 - 24.9kg/m2, overweight from 25.00 - 29.9 kg/m2 and obesity30.00 kg/m2. The result shows that there is a significant rise in the fasting blood sugar, the total protein in serum and the systolic pressure with the rise of the body mass. While the level of the cholesterol, triacylgcerol and the remnant lipoprotein of the patient has not been affected with the different of the body mass. The patients with natural body mass index show significant rise in the total and direct bilirubin levels as compared with other groups with no significant differences among the groups in the levels of uric acid, urea, creatine, and phosphorus and iron ionic. We conclude that there is a correlation between the body mass index and the systolic and diastolic blood pressure.

المستخلص: Type II diabetes mellitus is achronic diseas characterized by hyperglycemia resulting from defects in insulin secretion and insulin action or both and tissue resistante to insuline. This study was conducted in the Diyala province for the Type II diabetes patients which lasted for the period from beginning October 4102 to the end of May 4102 which aimed to evaluate some immunological indicators for patients infected with diabetes type two which included { assessment of the humoral immune by measuring the level of immunoglobulin (IgM, IgG) and the level of complement protein (C3, C2) by using the single radial immune diffusion assay and measuring the C - reactive protein (CRP) and determine the levels of Interlukin (IL - 01, IL - 01) by ELISA}. Atotal of (011) ablood sample was collected from patients with diabetes type two after diagnosis by a physician specialist in the clinic consulting in Baquba teaching hospital according to the criteria adopted by the World Health Organization for the diagnosis of diabetes type two, has been the number of males (24) percentage (20.11)% and the number of femals (22) percentage (21.02)% within the range of my age (32 - 11) years and collected (11) of blood sample from healthy volunteers ostensibly have been accredited as a group control, has been the number of males (32) percentage (21.33)% and the number of females is (42) percentage (20.14)% within the range of my age (31 - 44) years.Results of the study showed that the incidence of the disease rate a mong females (21.02)% than males (20.11)% with no significant difference statistically between the two groups of study for the sex, has found that age group (24 - 11, 11<) years recorded a high rate of disease (33.14)% and(32.12)% respectively while the age group (31 - 21) years percentage (1.11)% recorded lowest rate of disease whith high significant difference was noticed between the two groups.Furthermore results of the study showed low levels of immunoglobulin (IgM, IgG) in patients compared to the control group where found that the level IgM in patients (043.20124.22) mg/dl compared to the control group (434.24121.24) mg/dl and that the level of IgG in patients (0124.2110123.21) mg/dl compared to the control group (0103.32 ± 0442.14) mg/dl the results also showed low levels of complement proteins C3, C2 in patients compared to the control group it was found that the level of C3 in patients (01.00 ±31.14) mg/dl compared to the control group (030.02 ± 01.24) mg/dl and the level of C2 in patients (02.31 ± 4.11) mg/dl compared to the control group (20.231 4.13) mg/dl, and the results showed that the positivity of C - reactive protein in patients was (41.24)% compared to the control group was (1)% The results of the current study showed high level of IL - 01 in patients (410.24 ± 011.40) pg/ml compared to the control group (14.11132.43) pg/ml and the level of IL - 01 the results showed alow level of the IL - 01 in patients (13.13 ± 20.01) pg/ml compared to the control group (43.04 ± 40.03) pg/ml, inaddition to the study result showed agreat significant correlation between complement proteins (C3, C2) and the humoral immune (immunoglobulin IgM, IgG) as well as acorrelation between cellular immunity (IL - 01)and (IgM, C3).
