For the elucidation of the metabolic effects due to alcoholic drink and moldy rice intake author designed two experiments as follows. In the first experiment, sixty male and female rats, divided into six groups, 10 rats each in both sexes, were given 7.5% sucrose-30% alcohol solution (Jinro-Soju) and diets varied of fat content (2%, 7%, 30% of diet) and protein quality (casein, bean, anchovy) for 6 weeks. In the Second experiment, six groups of rats, 10 male rats each, were fed the diets containing zero, 5%, 10%, 25%, 50%, and 100% moldy rice contaminated Penicillium Islandicum and the experimental periods were 4 weeks and 6 weeks. The results of these studies due to the toxicity of alcohol consumption and moldy rice ingestion of the fatty liver production and the other effects are as follows. 1. Food intake of alcohol consumed groups decreased to 50%-70% of that of standard group. In the second study, there was no significant differences on food intake due to the different contents of moldy rice and experimental period. 2. On the view paint of body weight gain, the body weight of alcohol consumed groups gained much less than that of standard group, because food consumption was decreased due to alcohol ingestion. 3. In comparison of F.E.R. and P.E.R. between standard and experimental groups, there was no significant differences in this study. 4. As a matter of fact, there was no significance on the nitrogen balance in both studies. 5. From the result of hematology, R.B.C. counts, W.B.C. counts, hemoglobin, and hematocrit showed normal values in all groups including in this study. So we might conclude that the toxicity of alcohol and moldy rice do not effect significantly on blood picture. 6. The larger organs shrank on the range of 20%-70% of that against standard group in this study. The major reason for the shrinkage of organs might be account of decreased food consumption due to alcoholic drink. There was no great changes on the organ weight due to the ingestion of moldy rice. 7. The nitrogen content in various organs in both experiments was revealed at the normal level for the worst condition in terms of the least food intake. In other word, it was noteworthy that the concentration of nitrogen in various organs was kept at the normal ratio as standard groups under the circumstances of this study. 8. The lipid content in the liver of rats fed alcohol and diets containing either various lipid contents or protein quality did not increase. Hepatic lipids accumulation due to the dietary fat content was observed, but there wvas no significances among the compared groups. In the second experiment, the difference of hepatic lipid content between the moldy rice groups and standard group was not showed. In addition to the result of total lipid, hepatic free cholesterol, free fatty acid, and triglyceride did not change in both studies, we might conclude that the toxicity of alcohol and moldy rice could not effect on the hepatic lipid contents. 9. There was no significant differences on the serum glucose level between alcohol groups and standard group. In the second experiment, serum glucose level increase in 6th week compared with in 4th week, but there was no significant differences.
