ABSTRACT
In order to elucidate the effects of a lacto-ovo vegetarian diet on serum lipid levels, 91 male collegians residing in the Seoul area were recruited. The vegetarians did not smoke tobacco nor drink alcohol. Their anthropometric measurements, dietary intakes, and blood lipid concentrations were compared to age-matched omnivorous controls. The subjects were divided into four groups. The four groups were: 1) NSNDV (n=25): Non Smoking Non Drinking Vegetarians, 2) NSNDO (n=10): Non Smoking Non Drinking Omnivores, 3) SDO (n=37): Smoking, Drinking Omnivores, 4) SDM (n=11): Smoking Drinking Meat-eaters. Total serum cholesterol, HDL-cholesterol and hematocrit were analyzed. The results were as follows: Weight (p<0.05) and BMI (p<0.01) were significantly higher in SDM than NSNDV. Dietary protein (p<0.01), iron (p<0.05) and dietary lipids (p<0.01) from animals in NSNDV were significantly lower than the results in the SDM. Interestingly enough, we noted no significant differences between the four groups in terms of average total dietary protein, dietary lipids and dietary iron, total serum cholesterol, or HDL-cholesterol. Dietary fiber intake was significantly higher in NSNDV than in SDM (p<0.05). Weight, BMI, and total cholesterol were significantly positively correlated with animal protein (p<0.05) and animal lipid (p<0.01) intake. These results showed that vegetarian collegians who haven't smoked tobacco nor drunk alcohol evidenced lower body weight, BMI, and dietary animal lipid intake, but higher dietary fiber intake, than the other three groups. Additionally, intake of animal protein (p<0.001) and intake of animal lipids (p<0.001) were significantly positively correlated with body weight, BMI, and total serum cholesterol in male collegians.

The mean survival percentages for the concentrations 0.02 and 0.2 M NaNO2 in liquid MM after incubation for 24 hr at 280 were found to be 4.64 and 3.57, respectively. Out of 161 colonies tested from the concentration of 0.02 M, 64 auxotrophic mutants were isolated. However, out of 150 colonies tested from the concentration of 0.2 M, a total of 74 auxotrphic mutants was isolated. All these mutants reverted to the wild type. The mean survival percentages for the concentrations 10, 20 and 30 mg AC/20 ml solid CM and incubation for 4 days at 280 were 9.33,4.00 and 1.73, respectively. The mean survival percentages for the concentrations 10,20 and 30 mg AC/100 ml liquid MM and incubation for 4 days at 28° were 9.09, 6.66 and 5.64, respectively. The mean survival perecentages for the concentrations 10, 20 and 30 mg AC + 2 mg streptopencid/20 ml solid CM and incubation for 7 days at 28° were 0.67,0.12 and Q respectively. Three biochemical mutants were obtained from a sample of 127 colonies isolated from 30 mg AC + 2 mg streptopencid/20 ml solid CM. The mutants were ad, his and met requiring mutants. The mean survival percentages for the concentrations 0.05 and 0.1 ml DEA/20 ml solid CM and incubation for 4 days at 280 were 1.83 and 0.15, respectively. Twenty biochemical mutants were obtained from conidial suspensions treated with 0.05 ml DEA which gave a survival percentage of 1.83. These mutants were;- 3 his, 4 ad, 2 arg, 2 trypt, 1 ad or lys, 1 met or trypt, 1 ad or trypt, 1 his or trypt, 1 his or arg, 1 his or met and 21eu or trypt. The possibility for obtaining such latter mutants were discussed
