specific and non- specific cellular immune responses were studied in 20 amoebiasis cases and 10 controls. all the study cases and controls were indians living in varanasi, india. ten amoebic liver abscess cases were patients admitted to university hospital. ten non-invasive intestinal amoebiasis cases constituted the second study group. non-specific immune responses were studied using e-rosette...
the prevalence of hepatitis c virus (hcv) is approximately 3% around the world. this virus causes chronic hepatitis, liver cirrhosis and hepatocellular carcinoma. the effectiveness of interferon-α and ribavirin therapy is about 50% and is associated with significant toxicity and cost. hence, generating new vaccines or drugs is an obligation. however, there is no vaccine available for clinical u...
Studies during recent decade indicate that low calorie intake has potentiating effect on immune response . So the effect of fasting in holly month of Ramadan on cellular immune was studied. In this study , delayed type hypersensitivity (DTH) to purified protein derivative (PPD) test was selected to evaluate cellular immune response , because this test is not only very s...
objective: several vaccines against hiv have been investigated but none has been approved as an effective hiv vaccine. an approach that could induce stronger immune response against the pathogen is utilizing a multi-epitopic vaccine. this strategy was used in the design of several vaccines and resulted in improved immune responses. materials and methods: in this study a multi-epitopic fusion p...
Effect of different levels of date waste were studied on performance and immune responses of 240 Ross 308 broiler chicks in a completely randomized design with 5 treatments and 4 replicates and 12 birds in each replicate. The whole date waste were analyzed for chemical compositions and gradual levels of 0 (control), 5, 10, 15 and 20 percent of that were included into the diets which fed broiler...
objective: infectious microorganisms are major sources of illness and death worldwide, and the leading cause of death in neonates. effective vaccination of this age group is of particular importance. the lack of a response and greater susceptibility to tolerance are two major features that limit the effectiveness of vaccines in neonates. in this study we compare the cellular immune response gen...
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...
