objective(s): according to the occupationally risk of infection in staff workers who have direct contact with mycobacterium species, we investigated their immunological parameters and compared with healthy purified protein derivative (ppd) negative volunteers. materials and methods : we investigated 20 ppd positive volunteers working at tuberculin unit of razi vaccine and serum research insti...
silybum marianum, is known to have anti-inflammatory, hepatoprotective and anticarciogenic effects. the aim of this study was to compare effects of silymarin, rapamycin and fk506 on proliferation and apoptosis of human t cells stimulated with con a. peripheral blood mononuclear cells (pbmc) were stimulated with concavalin a ( con a) (5µg/ml) and then treated with different inhibitors (silymari...
t cells have been identified as key players in the pathogenesis of type 1 diabetes. however, the exact role of t-cell subpopulations in this pathway is presently unknown. the purpose of this study was to assess the expression pattern of two lineage-specifying transcription factors gata - 3 and t - bet , which are important in t helper type 1 (th1) and th2 cell development , respectively. gene e...
uterine lymphoma is a rare disease therefore, information regarding histologic type, immunophenotype of tumor cells and etiologic factors are limited. although secondary involvement of the genital tract occurs in up to 40% of cases• of disseminated lymphoma, lymphoma presenting with primary female genital tract . symptomatology is very unusual. we report a case of b-cell lymphoma in the uterine...
a purification procedure of pertussis toxin (pt) from submerged culture of bordetella pertussis (b.pertussis) strain 134 using adsorption and affinity chromatography was discussed. the yield of the resulting pt was approximately 37.5mg/l of concentrated culture supernatant. the polypeptide pattern of the purified pt was investigated by sds-page and showed five bands between 11 to 26 kda using l...
Background: Rheumatoid Arthritis patients are evaluated during treatment for various inflammatory factors such as C-reactive protein, Erythrocyte Sedimentation Rate, and Disease Activity Score, and other immune system-related factors. In the follow-up of patients with rheumatoid arthritis, hematologic factors associated with the immune system especially Platelet to Lymphocyte Ratio and Neutroph...
background: essential oils are found to have multiple active components which can show in vitro cytotoxic action against various cancerous cell lines. this study reports the in vitro cytotoxic effects of the essential oil from artemisia absinthium l. (asteraceae) growing wild in iran. methods: water-distilled essential oil of a. absinthium collected from ardabil, north-western iran, was examine...
