به منظور مقایسه تاثیر مصرف ویتامین e، ویتامین c و ترکیب ویتامین های c,e بر پاسخهای ایمنی سلولی و هومورال پس از یک فعالیت بدنی تا سر حد واماندگی در مردان تمرین کرده، 45 آزمودنی ورزشکار با میانگین سن 78/1 +-86/22 سال، قد 42/6+-07/174 سانتی متر، وزن 38/7+- 33/68 کیلوگرم، درصد چربی 04/2+-2/8 و حداکثر اکسیژن مصرفی 51/3+-44/47 میلی لیتر در دقیقه به ازای هر کیلوگرم از وزن بدن در چهار گروه ...
Introduction: Intense exercise leads to a decrease in immune system. The aim of this study was to investigate the effect of short-term garlic extract supplementation on some cellular immune system factors after intense exercise in karate athletes. Methods: Eighteen young men (with a mean age of 20.07±4.46, BMI 22.72±2.99 kg/m2) volunteered to participate in this semi-experimented...
OBJECTIVES To study the association between CD4/CD8 ratio and morbidity in HIV-infected patients on antiretroviral therapy (ART). METHODS The APROCO/COPILOTE cohort enrolled patients initiating a protease inhibitor-containing ART in 1997-1999. The association between occurrence of first non AIDS-defining severe events (NADE) and time-dependent measures of immune restoration was assessed by 4 ...
Objective(s): To investigate the systemic and local immune status of two surgical rat models of sciatic nerve injury, a crushed sciatic nerve, and a sciatic nerve transection Materials and Methods:Twenty-four adult male Sprague-Dawley rats were randomly divided into three groups: sham-operation (control group), sciatic nerve crush, and sciatic nerve transaction. Sciatic nerve surgery was perfor...
BACKGROUND Total CD4 T-cell counts predict HIV disease progression but do not necessarily reflect normalization of immune function. CD4/CD8 ratio is a marker of immune dysfunction, a prognostic indicator for non-AIDS mortality, and reflects viral reservoir size. Despite antiretroviral therapy (ART), recovery of CD4/CD8 ratio in chronic HIV infection is incomplete; we hypothesize enhanced CD4/CD...
سابقه و هدف: هدف از تحقیق حاضر بررسی رابطه بین لنفوسیت های t (cd8+, cd4+)، نسبت cd4+/cd8+ و سلول های کشنده طبیعی (cd56+) با حداکثر نبض اکسیژن در دختران فعال در پاسخ به فعالیت بدنی شدید بود. مواد و روش ها: این مطالعه نیمه تجربی با طرح اندازه های تکراری بر روی 16 دختر فعال 25-20 ساله انجام شد. جهت برآورد حداکثر نبض اکسیژن و پاسخ شاخص های ایمنی از آزمون نوارگردان (gtx) استفاده گردید. نمونه ...
The cancer-immune interplay and its role on the evolution of NSCLC might be disclosed through detection local systemic cues. Aim: To determine whether peripheral blood (PB) immune profiles may mirror clinically relevant tumor microenvironmental (TIME) features in resected patients. Tissue PB samples were prospectively collected at surgery from 80 consecutive stage I-IIIA cases. immunohistochemi...
Patients with pulmonary sarcoidosis frequently have increased numbers of lymphocytes and a high ratio of CD4+ to CD8+ T-lymphocytes (CD4/CD8 ratio) in bronchoalveolar lavage (BAL) fluid. Some investigators have suggested that these parameters can be used to distinguish sarcoidosis from other types of interstitial lung disease with a high degree of reliability. However, we hypothesized that the ...
The Aim of this study was to investigate the correlation of oral lesions in HIV positive patients with their CD4, CD8 cell count and CD4/CD8 ratio. 150 HIV seropositive patients of any age and sex were evaluated. Then analyses of data obtained were revealed Pseudo membranous candidiasis (P-0.0043) was the most common variant, mostly seen when CD8 count was increased (>500 cells/mm, P-0.05) and ...
A low CD4/CD8 ratio in elderly HIV-uninfected adults is associated with increased morbidity and mortality. A subset of HIV-infected adults receiving effective antiretroviral therapy (ART) fails to normalize this ratio, even after they achieve normal CD4+ T cell counts. The immunologic and clinical characteristics of this clinical phenotype remain undefined. Using data from four distinct clinica...
