[Stomach polyps in simians at the Sukhumi nursery]

Polyp-like changes in the mucous membrane of the stomach were noted in monkeys of the simian nursery in Sukhumi (100 cases). In 6 baboon hamadryads, in 4 Stum-tailed macaques and in one macaco rhesus they were diagnosed as the so-called polypous gastritis. In 5 Stum-tailed macaques there were noted gigantic folds of the pylorus. Of 84 macacos in 61 animals there was one polyp and in 23 macaques--2 and more polyps. Incidence of polyps among local monkeys was 0.48% in macaques rhesus and 2.3% in Stum-tailed macaques. Among imported monkeys the incidence of polyps was in macaques rhesus--0,31% and in Stum-tailed macaques--9,2%. Polyps in monkeys are considered as disregenatory formations, occasionally associated with parasitizing of helminths. In contrast to man, polyps in monkeys are not considered as precancer processes.
