This study has measured the pulmonary function by treadmill test for 6 young women who were in twenties, and analyzed the respiratory-circulatory function and the change of hormone and immune response after performing the exercise program (60% severity) for 10 weeks. The results are as follows; 1. 10 weeks regular exercise made a decrease in weight and body fat proportion, and improved the respiratory-circular function by increasing the maximum oxygen absorption and ventilation. 2. 10 weeks regular exercise made a significant increase in count of WBC, lymphocyte, and T lymphocyte, but a significant decrease in B lymphocyte. NK cell also showed an increase in counts, but insignificant. 3. 10 weeks regular exercise made a significant increase in blood norepinephrine level. Epinephrine and cortisol also showed an increase in count, but insignificant. In summary, it suggested that 10 weeks regular exercise improves the immune function by decrease in body fat, increase in respiratory-circular function and metabolic efficiency, and also by raising Th/Ts ratio (an increase in count of WBC, lymphocyte, and T lymphocyte, but a decrease in suppressor T lymphocyte).

The Clinical Study on the Body Weight Loss of Taeumin Inpatients in Stroke by Sasang Constitutional Medicinal Treatment. Purpose: It has been frequently noted that overweight and obesity have a stronger relationship to hypertension and diabetes mellitus than to the risk of stroke. The purpose of this study is to find out whether Sasang Constitutional Medicinal treatment in the stroke patients of Tae-um-in has an effect on local or general weight loss. Methods: Case-control study was applied. The experiment group is the 24 Taeumin stroke inpatients who were in hospital in Kyung-Hee Oriental Hospital from July 1, 2000 to October 1 and received Sasang Constitutional Medicinal treatment. The control group is the 13 Taeumin stroke inpatients who were in the hospital during the same period but didn't receive Sasang Constitutional Medicinal treatment. In the two groups, body weight, BMI, the skin fold(cm) of triceps, suprailiac, abdominal portion, and thigh and the circumference(cm) of wrist, biceps, triceps, and W/H ratio were compared and studied for three weeks. Results: 1. In the experiment group, there were 8 women and 15 men, 23 in total and in the control group, there were 5 women and 9 men, 14 in total. 2. From two weeks later, there was a significant decrease in the experiment group in weight loss, the ratio of loss, and BMI(p<0.05). 3. Concerned with the change in the skin fold of suprailiac portion, there was a significant decrease in each group(p<0.05). 4. Concerned with the change in the skin fold of Chunchu-Hyel portion(天樞穴), thigh and in the circumference of hip, W/H ratio, there was a significant decrease in the experiment group(p<0.05). 5. Concerned with the change in the value of Lipid Profile, GOT, and GPT, only Glucose(GLU) showed a significant decrease(p<0.05) in the experiment group(p<0.05). As Conclusion, Sasang Constitutional Medicinal treatment in the stroke patients of Tae-um-in has an effect on local or general weight loss.

This study was carried out to investigate the protective effect of Korean red ginseng water extract (KRG WE) on clinical chemical parameters in male guinea pigs acutely exposed to 2,3,7,8 tetrachlorodibenzo p dioxin(TCDD). Forty male guinea pigs(200 $\pm$20g) were divided into 4 groups. Normal controls(group 1) received vehicle and saline; group 2(single TCDD treated) received TCDD(5 g/kg, single dose) intraperitoneally; group 3 received KRG WE(200mg/kg, i.p.) for 2 weeks from 1 week before TCDD exposure; group 4 received KRG WE for 1 week since the day of TCDD exposure. Increase in body weight was retarded greatly by TCDD exposure. Body weight of animals in group 2 was significantly decreased starting 2 days after TCDD exposure. However, body weight of animals in group 3 increased throughout the experimental period, although the increasing rate was slower than that of group 1. Decrease in body weight was not observed during the experimental period in group 4. Increases in blood glucose, amylase, lipase, total cholesterol, triglyceride, GOT, GPT, and LDH levels by TCDD intoxication were significantly attenuated by the KRG WE treatment(p<0.05). These results provide a strong evidence that Korean red ginseng might be a useful protective agent against TCDD, an endocrine disruptor.

A mutation in the promoter region of uncoupling protein 3 (UCF3), specifically the -55C longrightarrow T transition, may influence an individual's energy metabolism and body weight. The objective of this study was to investigate the effect of a weight reduction program on endocrine functions and body fat distribution, related to UCP3 promoter genotype. Ninety overweight pre-menopausal female subjects participated in the weight reduction program at Yonsei University Hospital, and were placed on a calorie-restricted diet (300 kcal less than their daily requirements) for 12 weeks. After 12 weeks, all subjects on the program lost approximately 5% of their initial body weights and had lower Body Mass Index (BMI) values. Among the 90 women, 56 had a normal (without mutation) UCP3 genotype, while 34 women had mutations in the promoter region of UCP3. Despite similar weight reductions in both groups, a significantly higher decrease in abdominal adipose tissue was observed in the normal UCP3 genotype group, compared to the group with mutations. In particular, there was a significant reduction of fat at the lumbar 1 (Ll) level in the without-mutation group. Serum levels of total cholesterol, apolipoprotein Al were significantly decreased in the without-mutation group, by 4.4% and 5.7% respectively. Serum levels of hormones were not significantly changed in both groups artier the intervention. However, in the group without the mutations, the leptin level significantly reduced by 23.4% (p<0.001). Serum free fatty acid (FFA) concentration was significantly increased in the group with mutation following the weight reduction program. On the other hand, FFA responses were shown similar increases in both groups. In conclusion, although no difference was found in the magnitude of weight reduction in both groups, there were significant differences in body fat distribution and in endocrine function between the groups.

The toxicity test of ammonium persulfate was conducted to ensure of its potential toxic effects according to the single-dose acute oral toxicity study (OECD Guideline 423) and 90-day repeated dose sub-chronic oral toxicity study guideline (OECD Guideline 408) for establishing national chemical management system, and matching in the Globally Harmonized Classification System (GHS) category. In acute oral toxicity study, pasty stool, perineal contamination and temporary body weight decrease were observed after dosing 1st and 2nd challenge (300 mg/kg body weight). All test animals were dead within 6 hours after dosing at 3rd challenge (2000 mg/kg body weight). Therefore, the GHS class of test substance is considered class 4. In sub-chronic toxicity study, body weight changes, food consumptions, hematological, biochemical and pathological examination did not show any noticeable and significant differences between the administered (5, 20, 80 mg/kg body weight) and control (vehicle only) group animals. Based on these results, the no observed adverse effect level (NOAEL) is considered above 80 mg/kg body weight.

Plasma melatonin in the seasonal light-period is circadian rhythmically secreted. Maximal secretion showed at 14 o'clock in summer- and winter-like period, but minimal secretion showed at 5 o'clock in summer-like period and at 8 in winter-like period. These times of minimal secretions were at the beginning of light period. Plasma melatonin in the light period is secreted 62.5% more than in the dark period in summer-like period and 45.9% more in winter-like period. Total plasma melatonin in winter-like period is secreted 56.5% more than in summer-like period. The weights of testis(-20.8%) and body(-7.1%) were reduced in the winter-like period. By the increase of plasma melatonin in mice, body- and testis-weights are decreased, on the contrary by the decrease of plasma melatonin in mice, body and testis weights are increased. In view of the results so far achieved melatonin changes on the body weight and reproductive organ in mice. It is presumed that melatonin effects on the metabolism and sex hormone.

This paper describes the effects of thermally oxidized tallow on the serum lipids profile and radical scavenging activity (RSA) of the lipids extracted from the different tissues of the rabbits. Tallow was thermally oxidized at $130^{\circ}C$ for 9, 18, 27, 36 and 45 h respectively. Thermally oxidized tallow was fed to the local strain of Himalayan rabbits for one week. Results show that oxidation increases the formation of hydroperoxides and decrease the level of radical scavenging activity of the tallow. The rabbit serum lipids profile showed a dose dependent increase in triglyceride, total cholesterol and LDL-cholesterol. However, no statistically significant increase was observed in the HDL-cholesterol with an increase of oxidation time. Serum glucose and rabbits body weight decrease significantly (p < 0.05) and was highly correlated with the serum lipids profile. The percent RSA of the lipids extracted from the liver, brain and muscles tissues showed a significant decrease with respect to 0.5, 1.0 and 1.5 g/body weight as well as oxidation time. Data suggests that thermal oxidation and use of thermally oxidized beef tallow is harmful and therefore an alternative way of cooking should be used.
