Besides, measured total and differential WBC of the blood. Also it is trying to find out the relation between concentrations of these cytokines and biomarkers with the gender and disease course of Iraqi MS patients. The study involved 60 Iraqi who were diagnosed as MS patients. the selected patients were classified into two groups :  Pre - treated patients included 30 patients 15 male and 15 female whose age range between (18 - 56) years at the stage of the early diagnosis (RRMS).  Post - treated patients included 30 patients 15 male and 15 female whose age range between (18 - 53) years with treatment Interferon - β 1b (INF - β - 1b) intravenous immunoglobulin (Ig) pulse Methyl - Prednisolone MP (in acute relapses) for 3 days or 5 days. Besides, 20 healthy volunteers 10 males and 10 females matched the patients with age and gender were used as control subjects with age range between (20 - 50) years. They have attended to (Baghdad Teaching Hospital in the Medical City / Clinic for early detection of MS) in Baghdad during the period from November / 2013 to the end of April / 2014 for the diagnosis and treatment. The blood samples (6 - 8) ml were drown from all of studied cases in order to be used for immunological study by measuring their serum level of cytokines using Enzyme - linked Immunosorbent Assay (ELISA) and biomarkers; using Architect c4000 System (Abbott) for (TC, TG, LDL, VLDL, HDL and UA) and AIA - 360 system for (T3, T4 and TSH). Besides, measured total and differential WBC of the 2 ml of blood at using Cell - Dyn Ruby System.The Study has Reached the following Results : 1. The results showed that the average age in patients with MS is (34.43) years and age group (30 - 39) years are more susceptible to affected. 2. The study has showed the average serum level of IL - 10 were significant differences at the level of probability P<0.05 between the (pre - and post - treated) patients and the healthy control (35.54, 35.86 and 52.68) pg/ml, respectively. 3. The study furthermore, has showed the average serum level of TNF - α were significant differences at the level of probability P<0.05 between the post - treated patients (17.04) pg/ml and two group the pre - treated patients and the healthy control (14.81 and 14. 28) pg/ml, respectively.4. The result observed significant an increase in the concentration of serum level of TC, TG, LDL and VLDL at the level of probability P<0.05 in the pre - and post - treated patients as compared to the healthy control. 5. The result observed significant increase in the concentration of serum level of T3 and T4 at the level of probability P<0.05 in the pre - treated patients (1.08) ng/ml and (7.99) μg/dl, respectively and the post - treated patients (1.27) ng/ml and (8.68) μg/dl, respectively as compared to the healthy control (0.898) ng/ml and (6.95) μg/dl, respectively. 6. The study has showed a significant decrease in mean of the eosinophil for the pre - and post - treated patients (1.28 and 1.99) respectively as compared with the healthy controls (2.79).7. There is no relationship between the differential count of WBC and serum levels of (IL - 2, HDL, UA and TSH) and the pathogenicity of MS. 8. The research show significant increase in levels of TG and UA in male as compared with female, while level of HDL was significant increase in female as compared with male.

المستخلص: يمثل التهاب القرنية (Keratitis) مشكلة كبيرة قد تؤدي الى فقدان البصر احيانا نتيجة لخدش القرنية او فقدان الوضوحية في القرنية بعد اختفاء الالتهاب, ويعتبر فايروس الحلا (الهربس) البسيط - 1Herpes Simplex Virus - 1(HSV - 1))) هو من اهم العوامل المسببة لمرض التهاب ال | Keratitis is a medical term referring to inflammation of the cornea. It is a serious problem, resulting in everlasting loss of vision as a secondary effect to corneal scarring or loss of clarity of the cornea after the inflammation has disappeared. Most common microbes causing viral corneal keratitis is Herpes Simplex Virus - 1 (HSV - 1). HSV - 1 is a double stranded DNA (dsDNA) virus belongs to the Herpesiviridae. It affects the majority of peoples and its infections have been frequently without clinical manifestation. Ocular HSV - 1 infections caused multiple pathologies with possibly the most damaging being herpetic stromal keratitis (HSK). This study aimed to evaluate the abilities of the immunological and molecular indicators to diagnose herpetic keratitis in the infected and contralateral eye of patients, as well as to assess the immune status of both eyes by using tears and corneal scraping. Fifty - two patients with herpetic keratitis involved in this study, they attended the outpatient clinics / Ibn - AL - Haithum Teaching Hospital from March 2014 until December 2014. For the purpose of comparison, thirty, apparently healthy age matched control subjects were also included. Tears were collected from infected eyes of the 52 patients and from 16 out of the 52 patients contralateral eyes as well as from 30 controls. Corneal scraping had been obtained from 16 patient's infected eyes with corneal ulcers (epithelial ulcers) out of the total patients (52) with herpetic keratitis. Indirect immunofluorescence assay technique (IFA) was applied to measure levels of immunoglobulins (sIgA and IgG) in tears specific to HSV - 1. Realtime - polymerase chain reaction RT - PCR test was used to diagnose HSV - 1 in corneal scraping and tears of patients and control subjects. Interlukin - 17 (IL - 17A), tumor necrosis factor - alpha (TNF - ?) and interferon - gamma (IFN - ?) were measured in tear samples from patients and control subjects by the ELISA sandwich method. In tear samples; results of RT - PCR showed that 39/52 (75%) of the total patient's infected eyes were positive, 12/16 contralateral eyes were positive (75%). Corneal scraping and tear samples were taken from 16 patients with corneal ulcer, tear samples 14/16 (87.5%) positive result, while the corneal scraping samples were 16/16 (100%) positive, this indicates clearly that the cornea scraping is more appropriate and sensitive sample to detect HSV - 1 than tear. All controls were RT - PCR negative. IFA results of IgA and IgG in tears of infected and contralateral eyes were found to be more than the concentration in tears of control eyes with a highly significant p - value (0.0001). Comparison between the infected and the contralateral eyes indicates that both patients' eyes expressed a significant humoral immune response against HSV - 1. Although there were high significant differences between both the mean value of tears IL - 17A in infected and contralateral eyes with control, while the comparison between patient both eyes gave non - significant difference. The mean of tears TNF - ? and IFN - ? concentration in infected eyes of patients as compared to control was found to be highly significant (p= 0.0001). In this study we compared between patients infected eye with control to evaluate the performance of different markers in tear as HSV - 1specific sIgA, HSV - 1 specific IgG, IL - 17, TNF - ? and IFN - ? by using statistical test called Receiver Operating Characteristic (ROC) curve, the sensitivity for all studied parameters ranged from 80% - 96%.At the same time the comparisons between patient contralateral eyes and controls also revealed a high sensitivity range for these parameters ranged from 81% - 100%.These findings proved the ability of these markers in confirming diagnosis of HSV - 1 keratitis. In conclusion, the high percentage of RT - PCR results for corneal scraping sample indicate that this sample and by using this technique is more appropriate and sensitive to detect HSV - 1 than tear samples and detect the shedding of virus in both eyes of the same patients. Both patient eyes indicated that they were a good source for HSV - 1 diagnosis. In spite of the high sensitivity of all studied markers and their diagnostic ability, TNF - ? showed a higher sensitivity. To assess the immunological status of Herpetic keratitis patients, the studied markers TNF - ?, IFN - ? and IL - 17 were evaluated and showed a highly significant differences which indicated there was an active inflammatory condition combined with HSV - 1 infection and finally it can be concluded that both humoral and cellular branches of immune responses were involved in this disease.

المستخلص: Meningitis, which is inflammation of the membranes that surround the brain and spinal cord and can occur at any age, it is caused by infectious microorganisms include (Bacteria, Viruses, Fungi, and Parasites) and non infectious include (Drugs, Carcinoma and Inflammatory disorder), also requires early treatment with aggressive use of potent antimicrobials; otherwise the outcome almost ends fatally.The predominant causes of bacterial meningitis are streptococcus pneumoniae, Haemophilus influenzae type b (Hib) and Neisseria meningitides.This prospective study includes 40 cases of meningitis which have been admitted to the Baghdad Teaching Hospital and Child Welfare Teaching Hospital during the period from May to November/ 2014.The detection of meningitis causative agent were specified by using the standard biochemical and microbiological methods such as : Determination of protein and sugar in Cerebrospinal fluid, Differential and cell count, growth on Culture media and morphological appearance on Gram's stain.Confirmative tests were also done for identification of meningitis causative agent; these tests included Procalcitonin, IL - 6, CRP, D. Dimer. These confirmative tests have been crowned by PCR technique, by employing the detection of the bacterial gene.The DNA of bacteria was extracted from CSF of meningitis patients and detection the type of bacteria gene by using multiplex PCR technique that using primers to amplify each ply, bexA and ctrA gene.Out of 40 samples, 28 (70%) were identified as bacterial meningitis and 12 (30%) as viral meningitis, the result of PCR reaction revealed unmistakably that 20 (71.4%) of 28 were detected the bacteria (S. pneumonia, H. influenzaetype b and N. meningitides) as a causative agent, while there were no detectable infectious agents in the (40) control group included in this study.Viral meningitis patients showed the number of lymphocytes (31.92 cell/ mm3) and neutrophils (1.00 cell/ mm3), while the highest number of lymphocytes and neutrophils in bacterial meningitis caused by S. pneumoniae (77.08 cell/ mm3) , (28.86 cell/ mm3) respectively, so that there was significant difference between cells (lymphocyte and neutrophil) with study group at P value = 0.010, P value = 0.013 respectively. In microbiological examination 22.5% of patients group (40) showed positive result of culture and 7.5% showed positive result of gram stain.In biochemical tests, the detection of Cerebrospinal fluid's protein and glucose level was done. The level of protein concentrations in bacterial meningitis with S. pneumoniae (103.08 mg/l), H. influenzae (65.14 mg/l) and in other bacteria was (124.44 mg/l) which is higher than the protein concentration in viral meningitis (42.25 mg/l), and these results showed highly significant difference at (P=0.010). Results of glucose's level determination showed that there were no significant difference among the studied groups (P =0.2). Results of glucose's level determination showed the presence of non significant difference among the studied groups, (60.92 mg/dl), (43, 57 mg/ dl), (51.00 mg/dl), (41.50 mg/dl) consecutively appeared in bacterial, viral.Interleukin - 6 and Procalcitonin levels were diagnosed by Enzyme Linked Immunosorbent Assay, while the plasma D. Dimer and erum C - Reactive protein was diagnosed by NaycoCard technique.The current results showed the presence of high concentration of IL - 6 among meningitis patients, high concentration of serum IL - 6 appeared in bacterial and viral meningitis (28.68 pg/ml) when compared with control group (2.194 pg/ml) (P =0.001), while CSF IL - 6 show high concentration in bothbacterial and viral meningitis but with no significant difference (579.24 pg/ml) (P =0.0001). The data of this study showed, there was correlation between IL - 6 levels and neutrophil in meningitis patients. Interleukin - 6 had significant correlation with neutrophil (P =0.009). While no significant correlation appeared between IL - 6 and Lymphocyte.Procalcitonin results showed high concentration in bacterial meningitis group compared with viral and control group with a highly significant differences (P =0.0001).The results of CRP shown no significant differences between bacterial and viral group, while the levels of D. Dimer appear significant differences in both groups when compared with control group.Current study indicated that PCR, Procalcitonin and D. Dimer played an important role in diagnosis of meningitis disease.
