: Presence of antisperm antibodies (ASAs) in infertility and their adverse effects on fertility is a matter of controversy. The aims of this study were to determine the percentage of antibody positive sperms and rate of ASA positive sera in both fertile and infertile men and women, and to find the association between these antibodies and infertility. Methods: This study consisted of 29 fertile ...

Certain of the serological factors which vary with the individual have been reported,t together with data supporting the idea that age, sex, and blood group differences show some correlation with the antibody titers measured. This supplementary note deals with one of the antigen-antibody systems included in the former study, the essential feature here being the significance of the host origin o...

1. Sera of animals immunized against Japanese B encephalitis, Venezuelan equine encephalomyelitis, and Western equine encephalomyelitis viruses were fractionated by electrophoresis. 2. Electrophoretic patterns of rabbit sera before and after immunization against Japanese B virus showed no consistent change traceable to antibody formation. 3. To determine the antibody content, the electrophoreti...

Autoantibodies against soluble liver enzymes have been reported among alcoholics, but the targets of self-reactivity toward membrane proteins of the liver have not been characterized. Previously, among alcoholics, we found antibodies against ethanol-derived radical protein adducts that are dependent on cytochrome P-4502E1 (CYP2E1) for their formation. To further investigate autoantibodies again...

Background: Hydatid disease is characterized by long-term growth of hydatid cysts in the human. The glycan antigens have an important role in the immunology of hydatid cyst. In this study immunological reaction of host sera to different glycan antigens of the cyst, has been investigated. Methods: The antibody responses were tested to glycoprotein and glycolipid of the laminated layer (LL), c...

To investigate the seroprevalence of leptospiral infection in sheep in Ahvaz, southwestern Iran, bloodsamples were taken from 181 female sheep. Sera were stored at -20°C until use. They were initially screenedat serum dilution of 1:100 against six live antigens of Leptospira interrogans serovars pomona, canicola,hardjo, ballum, icterohaemorrhagiae, grippotyphosa using the microscopic agglutinat...
