Active Immunization against Poliomyelitis
1. A single intracutaneous inoculation with a subinfective dose of the virus of poliomyelitis produces considerable immunity. 2. Virus-serum combinations produce an appreciable immunity, providing just sufficient serum is used to protect the animal from paralysis. If there is an excess of serum, the degree of immunity is considerably reduced.
متن کاملThe Influence of Active Immunization Against Adrenocorticotropin Hormone on Galactopoiesis in Merino Ewes
Background:Chronic active adrenocorticotropin hormone (ACTH) immunization of ewes (with a previous history of immunization) resulted in elevated titres of antibody against ACTH, which induced a reduction in circulating levels of cortisol. Objectives:<span style="color: win...
متن کاملActive Immunization against Poliomyelitis in Monkeys
1. A combination of poliomyelitis virus and specific human serum is effective for the production of active immunity. 2. For each gram of active virus given intradermally as an emulsion, 6 cc. of human immune serum, injected subcutaneously, was required in our experiments to protect a monkey from paralysis. Some degree of active immunity was induced. 3. Immunity, without symptom of the disease, ...
متن کاملExperiments on Active Immunization against Experimental Poliomyelitis
The results obtained in this investigation indicate that poliomyelitis virus treated with tannin, sodium ricinoleate, or formalin does not constitute a satisfactory immunizing agent in monkeys against the experimental disease.
متن کاملReproductive effects of immunizing heifers against androstenedione and oestradiol-17 beta.
Heifers were treated with saline (Group I, N = 10), keyhole limpet haemocyanin (KLH; Group II, N = 10), androstenedione-KLH antigen (Group III, N = 14), or oestradiol-17 beta-KLH antigen (Group IV, N = 14). Booster injections were given to produce binding of greater than 10% at dilutions of 1:100 to 1:1000 (50% binding = 14 X 4 pg androstenedione and 9 X 5 pg oestradiol). The heifers were mated...
