exposure to high dosages of sulfur mustard (sm) can cause bone marrow depression, immune system suppression, impairment of the immune functions, and eventually results in diseases due to secondary immune disorders. in this article, we have studied the effects of this poison on iranian veterans by analysis of related published studies. in a systematic search, the effects of sm gas on iranian vic...

objective: hypericum perforatum (st. john's wort) has long been used in traditional medicine to treat a variety of internal and external ailments. the present study was done to evaluate the immumodulatory potentials of the hydroalcoholic extract of h. perforatum. materials and methods: twenty male balb/c-mice were randomly allocated in two equal groups and immunized with sheep red blood ce...

background: numerous evidences indicate that in some hiv-1 positive patients, the humoral and cellular immune responses are induced against hiv-1 proteins and this is inversely related to the progress of infection. objective: the aim of this study was the evaluation of the adenovectors containing hiv genes in induction of immune responses in mice. methods: the hiv-1 genes including gag p24, rev...

objective(s): sugar cane molasses is a commonly used ingredient in several food products. contrasting reports suggest that molasses may have potential adverse or beneficial effects on human health. however, little evidence exists that examines the effects of molasses on the different physiological systems. this study investigated the effects of sugar cane molasses on various physiological syste...

background and objective: since there are very few studies on the immunodeficiency state of the iranian survivors of pediatric acute lymphoblastic leukemia (all), we conducted this study to determine the prevalence of humoral defects in children with all at least one year after completion of chemotherapy. methods: in this study, antibody titers for mumps, rubeola, rubella, tetanus and diphtheri...

background: rhipicephalus ( boophilus ) annulatus tick is one of the most important ectoparasite of cattle. re­cently, several laboratories in the world have been concentrated on immunizing cattle against tick using various types of tissue extracts of ticks. the aim of this study was to evaluate the effect of immunization of cattle with tick salivary gland extract on biological parameters of ti...

We are surrounded by a sea of microorganisms that threaten to overwhelm us. This threat is made dramatically clear by the condition of AIDS, where the immune system is crippled by a slowly progressive infection extending over a period of years. In an AIDS patient, opportunistic infectious agents, including bacteria, viruses, and fungi, take advantage of the weakened immune system to invade and ...

Objective: The aim of this study was the evaluation of the Adenovectors containing HIV genes in induction of immune responses in mice. Methods: The HIV-1 genes including gag p24, rev...

Interaction of microgram quantities of highly purified rabbit anti-TNP antibodies with TNP-substituted HeLa, HEp-2, and L cells caused an intense stimulation of radioactive nucleoside ([(125)I]UdR and [(3)H]TdR) uptake which was maximal 24-72 h after exposure of cells to antibody. The stimulation of nucleoside uptake and presumaly DNA synthesis was shown to be immuno logically mediated because ...
