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 کاملThe Active Immunization of Sheep against Oestrone, Androstenedione or Testosterone to Increase Twinning
Procedures have been developed to produce consistent increases in ovulation rate in Merino ewes by immunization against the steroids, androstenedione, testosterone and oestrone. The procedures were based on experiments in the field over the period 1978-1981 using groups of 50 ewes for each treatment. The method uses selected steroid-human serum albumin conjugates, together with DEAEdextran adju...
متن کاملEffects of active immunization against gonadotropin releasing hormone on gonadotropin secretion after ovariectomy and testosterone propionate administration to mares.
Five lighthorse mares were actively immunized against gonadotropin releasing hormone (GnRH) conjugated to bovine serum albumin (BSA) to study the involvement of GnRH in luteinizing hormone (LH) and follicle stimulating hormone (FSH) secretion following ovariectomy (OVX) and after administration of testosterone propionate (TP). Five mares immunized against BSA served as controls. Immunizations 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, ...
