[Medical college students' self-appraisal of physical development].

The first-year students of a Moscow medical college based on 11 forms studied the specific features of their physical and functional development, by measuring the basic anthropometric indices--height and weight, chest circumference and excursion, lung capacity, the data of dynamometry, spirometry, a test of 10 squats per 10 sec, and breath-holding time. The findings characterize the physical and functional development of adolescents from this group and are a convincing basis for them to develop an individual long-term program for molding a healthy lifestyle.

[Epidemiologic aspects of using the dysenterin skin test in institutions for pre-school children for the purpose of detecting potential sources of infection].

A possibility of considerable reduction of dysentery morbidity in creches and kindergartens by isolation of portential sources of infection among the personnel and children revealed as a result of repeated bacteriological examination, positively reacting to dysenterin was demonstrated in two controlled epidemiological trials. The efficacy of this measure became much less when the test and the corresponding bacteriological examination were performed in the personnel alone. As a whole, the high incidence of positive results of the skin-allergic test in practically healthy children and adults, with an extremely rare isolation of shigellae in persons positively reacting to dysenterin, even in their repeated bacteriological examination, pointed to rather limited possibilities of an effective use of this test in antiepidemic practice for detection of potential sources of infection.
