Further Studies on Typhus Fever
1. Guinea pigs can be actively immunized against European typhus fever with homologous formalinized Rickettsia tissue cultures, provided sufficient amounts are injected. The method is suggested for practical application in man. 2. Serovaccination against European typhus fever can be successfully applied to guinea pigs by a variety of methods, the simplest of which consists of the injection of m...
متن کاملFurther Studies in Experimental Atherosclerosis
Cholesterol dissolved in sesame oil and injected regularly for a period of from 7 to 8 months into the jugular vein of four young dogs has caused in each animal larger and smaller nodules protruding to some degree into the lumen of the pulmonary artery and also here and there some diffuse thickenings, the whole closely resembling human arteriosclerosis. These changes commence at the origin of t...
متن کاملFurther Experimental Studies in Tetany
It has been our aim to determine in what particular the blood is altered during tetany so that it can produce hyperexcitability of the motor nerves. As a working hypothesis it has been assumed that (1) there may be a lack of calcium in the blood and tissues; (2) there may be a circulating poison which like an oxalate could render inactive the circulating calcium; and (3) there may be a substanc...
متن کاملFurther Studies on Immunity in Experimental Cryptococcosis
Following infection with 10(3) cells of Cryptococcus neoformans, progressive multiplication occurred in all tissues for 7 to 28 days. Thereafter, most mice gained control of the infection so that 3 to 6 months after inoculation, tissues were usually sterile or contained only small numbers of cryptococci. Survivors challenged 1 to 4 months after infection with 10(3) cells lived longer than contr...
متن کاملFurther Experiments in Typhus Fever
PRECISE INTERPRETATION OF OUR EXPERIMENTS SEEMS TO IMPOSE THE FOLLOWING CONCLUSIONS: Guinea pigs inoculated with washed Rickettsiae from Mexican typhus fever develop a disease identical with that resulting from inoculations with whole tunica scrapings, blood or other virulent material, and become thereby immunized to European typhus fever. The etiological agent of Mexican typhus fever is the Ri...
