The principles of Immunological methodologies have always based on the specificity and sensitivity of the antibody to its corresponding antigen. This study was designed to compare the specificity and sensitivity of antigens and antibodies in unprocessed serum and serum treated with Polyethylene glycol for precipitation and dissociation of immune complexes. One hundred (100) human sera samples w...

Polarized human T helper (Th) cells play a key role in the network of the specific immune system compartments. Cell-mediated immune response depends on activation of Th1-type cells, typically producing and releasing interferon-gamma and interleukin-2, whereas activation of Th2-type cells and production of cytokines such as interleukin-4, -5, and -10 are involved in humoral immune response and t...

coincidence of autoimmune diseases such as immune thrombocytopenic purpura (itp) with  immunodeficiencies has  been  reported  previously in  patients  who  suffered  from primary antibody deficiency (pad). but there is no original study on immunological profiles of itp patients to find out their probable immune deficiency. in this case-control study, itp patients’ humoral immunity was investig...

Leukocytes and macrophages, obtained from fibroma-immune rabbits and added to immune serum-fibroma virus mixtures, significantly increased the neutralization of fibroma virus as compared with immune serum alone. Immune cell suspensions from peritoneal exudates, regional lymph nodes, buffy coats, spleen, and liver were all effective in inhibiting fibroma virus. Approximately 2000 to 4000 immune ...

Abstract A comparative study of some parameters nonspecific immunity in the Angelinskii rubella-resistant variant scaly and mirror groups carp prespawning late feeding periods was carried out. The level antimicrobial properties C -reactive protein, immune complexes blood serum, phagocytic activity neutrophils were studied. showed interbreed inter-seasonal differences indicators. It is concluded...

In the in vitro model described normal serum or plasma alone does not detoxify endotoxin, as determined by the response of the thorotrast-primed rabbit to the injection of the reaction mixture after 1 hour of incubation at 37 degrees C. Partial detoxification, however, is achieved by serum or plasma after 3 hours of incubation of the same reaction mixture, as determined by the chick embryo test...

Background: Inflammatory responses in individuals exposed to sulfur mustard occur in some organs such as lung, skin and eyes. These organs manifest overreaction in cellular and humoral immune responses. Over a long period, the immune responses often continues toward chronic inflammatory processes with some interventions. Obviously some elements have been deregulated. Therefore, this study evalu...
