Background: Tuberculosis (TB) is still a severe problem in underdeveloped and developing countries. Diagnostic tests are unavailable every health institution, TB culture can take up to 45 days. Therefore, there need for cheaper, faster, easily accessible diagnostic methods that guide the diagnosis. This study aimed determine whether red blood cell distribution width (RDW), C-reactive protein (C...

fab (french – american- british) group determined a diagnostic classification for leukemia's. but in spite of some reports on different clinical findings and prognosis of hmc and lgl there is no place for hand- mirror cell leukemia and lgl leukemia in this classification. on the other hand, there are different ideas about causes of hand mirror cell and about different changes of large granlar l...

this study was performed in order to define the cellular immune response of 12 recovered cutaneous leishmaniasis subjects to different soluble antigens of the amastigote form of leishmania major. a soluble leishmanial antigen preparation (sla) derived from highly-purified amastigotes from infected nude mice was fractionated by mono q column using fast protein liquid chromatography (fplc) system...

lymphocyte cd4 + count, a standard laboratory test for staging of hiv infection, is expensive and unavailable in resource-restricted countries. total lymphocyte count (tlc) and hemoglobin (hb) are recommended as simple & inexpensive surrogates. the aim of this study was to assess the correlation, sensitivity and predictive power of these parameters as substitutes for cd 4 count. one hundred hiv...

background: cd4+ and cd8+ t cells are the main types of lymphocytes in cell-mediated immunity and play a central role in the induction of efficient immune responses against tumors. the frequencies of t cell subtypes in the peripheral blood and tumor tissues, and draining lymph nodes (dln) can be considered as useful markers for evaluation of the immune system in cancers. methods: in this study,...

background the picture that has emerged from studies investigating hiv infected people with gbv-c viremia is that they have lower plasma hiv viral loads in comparison with hiv-positive people who did not have the gbv-c viremia. objectives since gbv-c hiv coinfection has not been studied in iran, we have designed a survey to study the outcomes of gbv-c infection on hiv infected individuals. pati...

background : immunological response of host and parasite play a key role in developing vaccina­tion and immunization. the present study deals with the immune response and effecter mechanism, which was confirmed by migration inhibition factor (mif).  methods : the present work was conducted in parasitological lab of postgraduate department of zool­ogy, government holkar science college, indore (...

Background: T-2 mycotoxin belongs to the Trichothecene family and has damaging effects on the immune system. Objective: To investigate the toxic effect of T-2 toxin on the percentage of peripheral blood B lymphocytes and the potential protective role of selenium and vitamin E. Method: Frequencies of B lymphocytes (CD19+ ) were analyzed after injection of sublethal doses of T-2 toxin into Balb/c...

Erythropoietin (EPO) was first known as a factor for red blood cell proliferation and differentiation. Recent studies show the effects of EPO on immune system. In this study the antihuman leukocyte antibody (anti-HLA) titer were determined in five groups of rats, which had been sensitized with human lymphocyte. Also, the effects of stimulation's frequency and dose of recombinant human erythropo...
