Background: Asthma is an inflammatory airway disease; this inflammatory response can be attributed to reduced lymphocyte apoptosis in peripheral blood and in airway tissues.
The mechanism behind this could be attributed to decreased Bcl2 protein and increase Bax protein in peripheral blood lymphocytes of asthmatic patients.
Aim: to explore the mechanism behind decreased lymphocyte apoptosis in peripheral blood of asthmatic patients at cellular level.
Method: Ninety four subjects; (44) control and (50) patients were included in this study during the period from (2003) to (2004). The aspirated lymphocytes for each individual
were prepared and stained by immunocytochemistry to study the percentage of antiapoptotic Bcl-2 protein, pro-apoptotic Bax protein and their ratio.
Results: Our results showed that the percentage of Bcl2 protein in peripheral blood lymphocyte of asthmatic patients were significantly higher than control (33.23±11.56,
21.47±4.16)(P=<0.00001). The percentage of Bax protein in peripheral blood lymphocyte in asthmatic patients was significantly lower than the control (21.43±6.88, 24.89±4.8) (P-O.0323). Bcl2/Bax ratio was positive in asthmatic patients there was significant difference in comparison with the control (1.68±0.57, 0.87 ± 0.17) (P=<0.00001).
Conclusion: This study clarifies the role of these 2 proteins in the process of reduction of apoptosis in peripheral blood lymphocytes of asthmatic patients.
Background: Asthma is a disease of the airways characterized by chronic inflammation associated with airway hyper-responsiveness and airway wall remodeling. Aims of the study: The aims of this study was to determine the prevalence of oral manifestations , identify different microorganism from oral micro flora and determination of salivary IgA and salivary flow rate in asthmatic patients taking different dose of Prednisolone in comparison with control group. Subjects, materials and methods: The study included 17 patients under treatment with Prednisolone (10-20 mg),15 patients take (20-30 mg) of Prednisolone and other 18 patients take (30 – 40mg) of Prednisolone, and 25 healthy control group (10 male and 15 female).

Coffee bean contains bioactive compounds including caffeine and chlorogenic acid (CGA) that have a stimulant effect and are used for combating fatigue and drowsiness, and enhancing alertness. However, when the coffee bean was processed in the form of green coffee bean (GCB) extract, it has an unpleasant flavour and limitations instability, activity, and bioavailability. This study aimed to produce microcapsules of the GCB (Coffea canephora) ethanolic extract containing considerable amounts of the bioactive compounds for nutraceutical supplements. The GCB ethanolic extract was microencapsulated by spray drying using a whey protein concentrate (WPC) biopolimer. The particle size (PSA), morphology (SEM), and physicochemical charact

Show MoreBackground: Oral carcinogenesis is a molecular and histological multistage process featuring genetic and phenotypic markers for each stage, which involves enhanced function of several oncogenes and/or the deactivation of tumor suppressor genes, resulting in the loss of cell cycle checkpoints. The progression towards malignancy includes sequential histopathological alterations ranging from hyperplasia through dysplasia to carcinoma in situ and invasive carcinoma. The p16 gene produces p16 protein, which in turn inhibits phosphorylation of retinoblastoma, p16 play a significant role in early carcinogenesis. Human papillomavirus is a well established heterogeneous virus and plays an important role in oral cancers. The aims of the study were to

Show MoreThe ABO blood group system is highly polymorphic, with more than 20 distinct sub-groups; study findings are usually related to ABO phenotype, but rarely to the ABO genotype and animal models are unsatisfactory because their antigen glycosylation structure is different from humans. Both the ABO and Rh blood group systems have been associated with a number of diseases, but this is more likely related to the presence or absence of these tissue antigens throughout the body and not directly or primarily related to their presence on RBCs. A total of fifty-two 52 patients without complication of DMII, two hundred sixteen 216 patients with complication of DMII and seventy-one 71 person as healthy control were included in the study.

These include marked progress in understanding the molecular biology of normal and neoplastic lymphoid cells and recent advances in molecular genetics techniques. Among molecular markers, p-53 cancer suppressor gene has been widely studied.
Objectives: is to correlate p-53 protein expression in chronic lymphocytic leukemia, as examined by immunohistochemical method, with some pathological and clinical parameters.
Patients and methods: this is a retrospective study; whereby archival paraffin-embedded bone marrow tissue blocks along with the clinical and hematological records of fifty patients (35 males and 15 females), wi
The secondary sex ratio (SSR) is affected by many factors, including the concentration of hormones and infection with some pathogens such as Toxoplasma gondii. This study aimed to evaluate the effect of hormone variability concentrations and toxoplasmosis infection on the secondary sex ratio. 150 pregnant women were selected, 60 infected with late toxoplasmosis (LT), 60 infected with early toxoplasmosis (ET) and 30 seronegative to toxoplasmosis. After tracking the birth outcomes of these women, we calculated SSR in each group. During the second and third trimesters of pregnancy, estrogen, testosterone, progesterone, TSH, T4 and T3 concentrations were measured. The results of the three groups were compared. The results s

Show MoreBackground: several new inflammatory markers have emerged as strong predictors of cardiovascular disease in healthy and non-healthy subjects, one of these markers is hs-CRP, which has been proposed as independent risk factor for cardiovascular disease, and it is positively associated with body weight. Little is known, however, about the utility of hs-CRP and other biomarkers in obese hypertensive Iraqi post menopausal women.The aim of study is to examine the hypothesis that there is a relation between obesity, hypertension and a chronic low-grade inflammatory status (represented by high hs-CRP).
Patients and Methods: A total number of 99 postmenopausal women classified into obese hypertensive group (
