This study was designed to observe the effect of two levels of dietary protein intake on the development and growth of rats from fetus to adult. The pregnant rats were fed either 20% casein diet or 7% casein diet. After weaning or two weeks postweaning, some of the pups from malnourished mothers were rehabilitated by feeding 20% casein diet. The results were. 1. On the 14th day of gestation, no differences were found in weight and total body fat or protein between fetuses from dams fed 7% casein diet and those from those from 20% casein diet. 2. The birth weight of the pups from 7% casein diet group were significantly lower than those from 20% casein diet group. 3. After rehabilitation, the total body fat and protein of low protein group were not different from those of control group when they were compared at the same body weights regardless the age of rats or the duration on the low protein diet. 4. The nitrogen retention of low protein group, after rehabilitation, was higher than that of control group when they were compared at the same body weight.

This study was carried out to investigate the effects of garlic vinegar supplementation on changes in body weight, blood glucose and serum triglyceride and cholesterol. Rats were fed a cholesterol-diet with or without garlic vinegar (20% garlic juice )supplement for 28days. Body weights in rats fed a diet containing garlic vinegar were significantly lower than those of control rats. The concentration of plasma glucose, total cholesterol . LDL-cholesterol , and HDL-cholesterol were not significantly different between the two groups for a period of up to four weeks. However, the concentration of plasma triglyceride was slightly decreased in the garlic vinegar-supplemented group. Results suggest that the supplementation of garlic vinegar is beneficial for weight reduction in high-cholesterol fed rats.

The purpose of this study was to compare the body compositions and food behaviors of middle aged men with different obesity indices. The subjects were 62 middle aged men who lived Gunsan city. Heights, body weights, soft/lean masses, fat masses, percentages of body fat, and fat distributions were measured. Food habits and health-related lifestyle habits were evaluated based on questionnaires. The subjects were assigned to one of the following groups based on their percentage of body fat ($\%$Fat) ; normal, overweight and obesity. The results were as follows: their heights, fat masses, percentages of body fat, WHR, RBW, BMI and fitness scores were significantly higher in the obese subjects when compared to the normal and overweight subjects. Self-perceptions of weight and desires of weight control were significantly related with their percents of Fat. The overweight and the obese groups skipped meals, ate supper out, ate snacks, smoked tobacco, and exercised less frequently than the normal group. There were no significant differences in the scores of the dietary habits and drinking of alcohol among the three groups. Therefore, proper nutritional education on regular meals and intervention is required if middle aged men want to be of normal weight and have healthy lifestyles.

The acute and subacute toxicity of New Wonbangwoohwangchungsimwon (NSCH) which was used l-muscone as substitutive material of musk were investigated in S.D. rats. In intraperitoneal acute toxicity test, rats were injected intraperitoneally with five dosages of 0, 500, 710, 1,000, 1,410 and 2,000 mg/kg. Body weights were significantly decreased at 500 and 710 mg/kg dose group in male and abnormal autopsy findings were founded in both sexes at all dose. Intraperitoneal $LD_{50}$ of NSCH was 1,088.3 mg/kg in male and 1159.3 mg/kg in female rats. In the subacute toxicity study, NSCH was administrated orally to both sexes of rats for 4 weeks as several doses(0, 320, 800, and 2,000 mg/kg). There were neither dead animals nor significant changes of body weights during the experimental period. In addition, no differences were found between control and treated groups in clinical signs, urinalysis, hematology, serum biochemical analysis, and other findings. Above data strongly suggest that no observed adverse effect level of NSCH might be over 2,000 mg/kg/day in this study.

The objective of this experiment is to investigate neurobehavioral and developmental effects of fumonisin B1 (FB1) after prenatal FB1 administration in rats. FB1 (0.8 or 1.6 mg/kg) was orally exposed to pregnant rats during gestational days 13 to 20, whereas the vehicle alone was administered to control group. Maternal and offspring body weights, physical landmarks of incisor eruption, eye opening, testes descending and vaginal opening, open field activity, running wheel activity, and complex maze performance were included as endpoints for developmental and neurobehavioral measurement. Maternal body weights were not signfficantly altered after FB1 exposure. Percentage of maternal weight gain difference between control and 1.6 mg/kg FBI groups was about 4%. Pre- and post-weanling weight of offsprings after prenatal exposure to FB1 was not signfficantly changed, suggesting that FB1 at 0.8 or 1.6 kg/kg doses may not cross the placenta. Significant gender difference in running wheel activity on postnatal days 57 to 63 and complex maze performance on postnatal days 75 to 78 was observed.

Two experiments were conducted to investigate into the effects of replacing maize with a mixture of cassava root and leaf meal (CRLM) on the performance of broiler chickens. In experiment 1, CRLM replaced 50 or 100 percent of maize in the control diet. In experiment 2, the 100 percent CRLM based-diet was fortified at a further 3 percent level with coconut oil. A total of 180, one-day old Shaver Starbro chicks, raised up to 49 days of age, were used. There were no significant (p<0.05) differences in final body weights, feed intake and feed efficiency between the control group and the group fed the diet in which 50 percent of the maize was replaced with CRLM. At the 100 percent level of replacement of maize with CRLM, however, final body weights, feed efficiency and carcass yields, were significantly (p<0.05) reduced. Dressing percentage and feed intake were not affected (p>0.05) by level of substitution of maize with CRLM. In experiment 2, when the diet in which all of the maize was replaced with CRLM was fortified with coconut oil at an additional 3 percent level, broiler performance improved and equaled (p=0.05) that obtained on the control maize diet. It was concluded the CRLM can replace 50 percent of maize in broiler diet without adversely affecting performance. However, for the complete replacement of maize with CRLM, it is necessary to further supplement such a diet with a high energy density ingredient if broiler performance is to be maintained.

본 실헐은 P-치약의 햄스터의 구강점막에 대한 자극성을 평가하기 위해 수행되었다. 시험 시작일에 햄스터의 오른쪽 협낭에 P-치약, 죽염치약, 증류수와 대조물질을 각각 적용하고 14일 동안 유지하였다. 점막 자극성을 평가하기 위하여 임상증상, 치사율, 체중 변화와 육안적, 조직병리학적 관찰을 실시하였으나 모든 군에서 사망한 동물이나 체중의 유치적인 변화는 관찰되지 않았으며, 특히 증류수는 처치한 군과 P-치약을 처치한 군의 육안적, 조직병리학적 관찰 소견의 차이가 매우 미미하였다. 이런 결과들을 종합해 보았을 때, P-치약은 햄스터 구강점막에 대한 자극성의 거의 없는 것으로 사료된다.

An experiment has been carried-out on physiological responses in Saanen, Anglo Nubian and Toggenburg goats at different body weights and feed intakes during treadmill exercise at $30{^{\circ}C}$ environmental temperature (ET). The results showed that respiration rate (RR) was significant between time ${\times}$ breed interaction (p < 0.01), with values for the Anglo Nubian being least, while the Saanen was intermediate. With time, RR differed significantly, and after 1 h the respective RR were 238, 221 and 303/min in the Saanen, Anglo Nubian and Toggenburg. With time the rectal temperature (Tr) increased gradually and after 1 h exercise mean values were 40.8, 41.3 and $40.7{^{\circ}C}$ in the Saanen, Anglo Nubian and Toggenburg respectively. Rump skin temperature (RTs) values differed significantly between Anglo Nubians and Toggenburgs, with the differences averaging 0.3, 0.6, 0.4 and $0.4{^{\circ}C}$ after 15, 30, 45 and 60 min exercise respectively. With breed, highest loin skin temperature (LTs) values were in the Anglo Nubian, with an overall mean of $37.9{^{\circ}C}$ (p < 0.05).
