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 کاملActive immunization against somatostatin alters regulation of gastrin in response to gastric acid secretagogues.
We have examined the coupling between somatostatin, gastrin, and gastric acidity, using sheep chronically immunized against somatostatin. All immunized sheep had high-titer (3.2 × 105 ± 1.1 × 104 M), high-affinity (1.5 × 1011± 1.2 × 1010 l/mol) antibodies. However, basal gastrin and gastric acidity were similar to those in control animals, indicating that an inhibitory somatostatin tone was not...
متن کاملOvarian and hormonal response of female goats to active immunization against inhibin.
This study was conducted to evaluate the effect of active immunization against inhibin on hormonal levels and the ovulation rate in goats. Ten adult Shiba goats (Capra hircus) in two groups were used in this study. The first group was injected with inhibin vaccine (immunized, n=5) and the second group was injected with Freund's adjuvant (control, n=5) followed by three booster injections at 4-w...
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 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...
