Studies on the agent of infectious hepatitis. III. The effect of skin tests for infectious hepatitis on the incidence of the disease in a closed institution.

At the onset of an epidemic in a closed institution about one-fourth of the inmates were skin-tested. During the year following the skin test, 5 cases of hepatitis with jaundice were recorded among 320 skin-tested individuals with unknown histories, one in the 144 skin test-positive, and 4 in the 176 skin test-negative subjects. In contrast 112 cases occurred among the 825 non-skin-tested individuals. Thus, the incidence of jaundice in the skin-tested group was 1.6 per cent as against 13.6 per cent in the non-skin-tested individuals. Possible explanations for this observation have been discussed.

Antimicrobial agents in the prevention of dietary hepatic injury (necrosis, cirrhosis) in rats.

The effect of various antimicrobial agents, such as aureomycin, terramycin, streptomycin, chloromycetin, penicillin, polymyxin, and sulfaguanidine on the development of massive dietary necrosis of the liver in rats has been studied. Delay in the production of hepatic necrosis was obtained from aureomycin and, to a lesser extent, from terramycin and streptomycin. Indication of temporary protection was shown by sulfaguanidine, whereas chloromycetin, polymyxin, and penicillin were not protective. B(12), added alone, or in combination with aureomycin, to the basal experimental diet had no influence on the development of hepatic necrosis. A combination of pectin with streptomycin enhanced the protective effect of the antibiotic. All the antimicrobial agents tested, without relation to their effect on hepatic necrosis, produced temporary stimulation of growth in the experimental animals. The beneficial effect of aureomycin was not limited to the delay of hepatic necrosis but manifested itself also in the prevention of hepatic cirrhosis in rats fed a low protein (casein)-high fat diet. In contrast to control animals showing the usual combination of cirrhosis and renal changes, the rats receiving supplements of aureomycin were free of both cirrhosis and renal changes. The rats receiving aureomycin took more food in and gained weight. No microscopic alterations were seen in the pancreas of the control rats with cirrhosis. In both groups of experiments (necrosis and cirrhosis) the antimicrobial agents, with the exception of penicillin, were given mixed with the food. Their possible effect on the intestinal flora is discussed.
