Poliomyelitis Vaccine
The Epidemiology of poliomgelitis has been investigated in our country Pasteur Institute; the incidence of Poliomgelitis, after the age of 4 years i's rare, in Iran. Passive antibody of maternal origin do not interfere with production of active antibody after immunization. Inactivated Polio Vaccine (salk) has been effective in reducing the incidence of poliomgelitis by approximately 90 per ...
متن کاملStudies on the Purification of Poliomyelitis Virus
Results of experiments on the preparation of high molecular weight constituents from normal and poliomyelitis-infected medullae-cords are presented. Relatively large yields were obtained from glycerolated normal or infected tissues or from tissues that had been stored at -10 degrees C. for a few days. When the frozen tissues were stored for several weeks, the amount of sedimentable nitrogen iso...
متن کاملStudies on Variants of Poliomyelitis Virus
Attempts were made to "convert" highly virulent strains of the 3 immunologic types of poliomyelitis virus (Mahoney, Y-SK, and Leon) into avirulent variants. Tests involving intracerebral, intramuscular, or oral administration of virus to cynomolgus monkeys indicated that mere propagation in cultures of kidney tissue of cynomolgus monkeys had no effect on virulence when single or small numbers o...
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 کاملThe Effect of Cataphoresis on Poliomyelitis Virus
1. Under ordinary conditions of hydrogen ion concentration the virus of poliomyelitis, as such, or associated with particles in fine suspension, migrates in an electrical field to the anode. It follows that the virus bears an electronegative charge. 2. By means of cataphoresis, the virus can be recovered from a non-infective mixture of virus and specific immune serum. 3. By the same means it is...
