the effect of anti-follicular stimulating hormone (fsh) on testicular lipid and the specific activity of testicular enzymes of the isocitrate dehydrogenase (icdh), pyruvate/malate dehydrogenase (mdh) and malic enzyme involved in lipogenesis were studied in mature bonnet monkeys, macaca radiata. immunization of monkey with anti-fsh for 24 days did not produce any significant changes in the body ...

background and objectives: enterohemorrhagic escherichia coli (ehec) o157:h7 has been recognized as a major food borne pathogen responsible for frequent hemorrhagic colitis and hemolytic uremic syndrome in humans. cattle are important reservoirs of e. coli o157:h7, in which the organism colonizes the intestinal tract and is shed in the feces. objective: vaccination of cattle has significant pot...

background: to control avian coccidiosis with drug-independent strategy effec-tively and safely, multivalent hyperimmune egg yolk immunoglobulin (igy) was prepared and its ability to protect against eimeria tenella infection was evaluated. methods: hens were orally immunized with live oocysts of 5 species of eimeria for six times, antibody titers in serum and yolk were monitored by indirect enz...

The combined effect of active and passive immunization with chemotherapy was studied in the treatment of rapidly growing methylcholanthrene-induced fibrosarcoma KMT-17 in the WKA rat. In active immunization, live Friend virus-infected KMT-17 tumor cells were inoculated s.c. into rats a few hr after KMT-17 transplantation. The survival rate with active immunization alone was only 19.0%. In passi...

Passive oral immunization with O-antiserum was found to protect guinea pigs against fatal enteric cholera. The number of vibrios recoverable from the intestines of infected animals was not noticeably reduced by active and oral passive immunization. Passive immunization by the intraperitoneal route was not protective even though high titers of circulating antibody were obtained shortly after inj...
