This experimental study was designed to investigate the effects of Yukgunja-tang(YGJT) on the change of weight and serum total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, free fatty acid, total lipid, phospholipid level in obese mice induced by high fat diet. I fed normal group fed normal diet and administered DDW 0.2㎖ during 7 weeks, control group fed high fat diet and administered DDW 0.2㎖ during 7 weeks, sample A group fed high diet and administered YGJT 300mg/kg 0.2㎖ during 7 weeks, sample B group fed high diet and administered YGJT 500mg/kg 0.2㎖ during 7 weeks. The results were as follows ; 1. Sample A and Sample B were significantly decreased body weight(4weeks) and serum free fatty acid level in comparison with control group. 2. Sample A was significantly decreased body weight(7weeks), serum total cholesterol level and serum total lipid level, but significantly increased serum HDL-cholesterol level in comparison with control group. 3. Sample A was decreased serum LDL-cholesterol level, serum triglyceride level and serum phospholipid level in comparison with control group. 4. Sample B was increased serum HDL-cholesterol level in comparison with control group. 5. Sample B was decreased body weight(7weeks), serum total cholesterol level, serum LDL-cholesterol level, serum triglyceride level, serum total lipid level and serum phospholipid level in comparison with control group. According to above results, I suggest YGJT is able to be used for the herbal medication of obesity.

Objectives: We investigated the effects of changes in obesity and life style factors, such as cigarette smoking, alcohol drinking, and exercise, on the changes in blood pressure and serum cholesterol among Korean men. Methods: This study included 7,205 healthy male employees in the steel manufacturing industry. Each subject underwent health examination in 1994 and was re-examined in 1997. The study subjects were classified into four categories, according to changes in body mass index (BMI) (loss; stable; mild gain: severe gain), cigarette smoking (quitter; nor-smoker; smoker continued; smoker started), alcohol drinking (quitter; non-drinker; drinker continued; drinker started) and exercise (more exercise; continuous regular exercise; continuous irregular or no exercise; less exercise), respectively. We evaluated the relationship between the categories of change in those independent variables and the changes in blood pressure and serum cholesterol, adjusted for BMI in 1994 and age by analysis of variance. Results: The change in systolic blood pressure was positively associated with the changes in BMI (p<0.001) and drinking (p=0,001), but negatively with smoking (p=0,004), compared to the first category of each independent variables. The systolic blood pressure was significantly less increased in the continuous smoking group than quitter or hon-smoker. The changes in diastolic blood pressure and serum cholesterol appeared to have statistically significant linear relationships only with the change in BMI. The change in exercise showed a marginal significance with diastolic blood pressure (p=0.088). Conclusions: These prospective data emphasize the importance of obesity as a determinant of the changes in blood pressure and serum cholesterol. In addition, the changes in smoking and drinking habits can affect systolic blood pressure.

The present experiment was performed in order to know the therapeutic effect of laserpuncture and aquapuncture with methionine on recovery in artificially induced hepatic damaged rats by carbon tetrachloride. The animals were divided into control, laserpuncture and aquapuncture groups. The changes of serum enzyme activities(ALT and AST), serum total protein contents, protein fractions(ALB and GLB) and A/G ratio were examined before and after application of laserpuncture and aquapuncture. In change of serum ALT activity, recovery with treatment in laser and aquapuncture groups was more rapid than that of control. The significant decreased value was shown on 3rd(P < 0.05) and 7th day(P < 0.01) after treatment in laserpuncture group and on 7th day(P < 0.05) after treatment in aquapuncture group. In addition, significance was detected on 2nd day(P < 0.05) between laserpuncture and aquapuncture groups. In change of serum AST activity, recovery with treatment in laserpuncture and aquapuncture groups was more rapid than that of control. The significant lower values on 7th day(P<0.01) in aquapuncture groups. In addition, significant low value was detected on 7th day(P < 0.05) in aquapuncture group comparing with that of laserpuncture group. The change of serum TP contents showed similar pattern in control, laser and aquapuncture groups. The significances were detected on 7th day(P < 0.05) in both experimental groups. In addition, significant high value was detected on 2nd day(P < 0.05) in laserpuncture group comparing with that of aquapuncture group. The change of serum ALB content with treatment in laser and aquapuncture groups was more rapid than that of control. The significant high value was shown on 2nd(P < 0.01), 5th(P < 0.05) and on 7th day(P < 0.01) in laserpuncture group. In addition, significant high value was detected on 3rd day(P<0.01) only in aquapuncture group comparing with laserpuncture group. The change of serum GLB content showed similar pattern among groups. The significant low values were detected on 2nd day(P < 0.05) in aquapuncture group. In addition significant high value was detected on 5th day(P < 0.01) only in laserpuncture group comparing with that of aquapuncture group. In change of A/G ratio laser and aquapuncture groups showed higher values than that of control. The significant high values were detected on 1st day(P < 0.Of) and 2nd day(P < 0.05) in laserpuncture group, and on 1st day(P < 0.05) and 2nd day(P < 0.01) in aquapuncture group. In addition, significant high value was detected on 5th day(P < 0.05) in aquapuncture group comparing with that of laserpuncture. Considering above findings collectively, it was considered that both laserpuncture and aquapuncture were effective; aquapuncture was more effective than laserpuncture for recovery of hepatic damage.

This study was undertaken to investigate protein effects on the adaptation of shift work. Since biorhythms differ according to the time of day, an investigation of the change of metabolism during day-shift and night-shift was undertaken by dividing twenty 3-shift worker into two groups: dormitory diet group and milk & egg supplemented group. Between the two groups, estimations were made on the concentrations of serum protain, albumin, cholesterol and cortisol and the excretion of vanilymandelic acid(VMA), creatinine and nitrogen in urine. The results are summarized as follows: 1. Serum ingredients were gathered from workers at 6:00-7:00h and 14:00-15:00h on the day of their change from morning shift(6:00-14:00h) to night shift(22:00-6:00h). On examnation of the serum ingredient it was found that, in dormitory diet group only the concentrarion level of serum albumin showed a change of rhythm adapted to night work, and in the milk & egg supplemented group the concentration levels of serum protein, albumin and cholesterol all showed a change of rhythm adapted to night work. Serum cortisol of both groups showed the same rhythm as during morining shfits, which implied nonadatation to night work, but the concentration was observed to be lower. 2. Excretion of urinary VMA and nitrogen were higher during night work than during morning work: they were also higher on the 6th day than on the 1st, in comparing the two groups, excretion of VMA was higher among the dormitory diet group, whereas the opposite was ture for excretion of nitrogen among the milk & egg supplemented group. There was no sign of difference in excretion of cretinine among the two experiment groups.

We investigated the exercise-induced changes in the serum concentration of several minerals in horses. Four welltrained Thoroughbred horses performed exercise for 5 d. The blood hemoglobin (Hb) concentration increased during exercise, recovered to the pre-exercise level immediately after cooling down and did not change again up till the end of experiment. The changes in serum zinc (Zn) and copper (Cu) concentrations were similar to those of blood Hb during the experiment. The serum magnesium (Mg), inorganic phosphorus (Pi) and iron (Fe) concentrations also increased during exercise. Though the serum Pi concentration recovered to the pre-exercise level immediately after the cooling down, it decreased further before the end of the experiment. The serum Mg concentration was lower immediately after cooling down than its pre-exercise level but gradually recovered from the temporal reduction. The recovery of the serum Fe concentration was delayed compared to that of other minerals and recovered 2 h after cooling down. The serum calcium (Ca) concentration did not change during exercise but rapidly decreased after cooling down. As a result, it was lower immediately after cooling down than its pre-exercise level. It recovered, however, to the pre-exercise level 2 h after cooling down. The temporal increase in the serum concentrations of all minerals except Ca is considered to result from hemoconcentration induced by exercise and the stable concentration of the serum Ca during exercise is possibly due to its strict regulation of homeostasis. These results indicate that the serum concentration of each mineral responds differently to exercise in horses, which may be due to the difference in metabolism among these minerals.

The purpose of this study was to investigate the relationship among nutritional status of copper and zinc, serum leptin, and lipids of 99 middle school girls residing in kyunggi-do, Korea. Subjects were divided assigned to one of two groups such as normal (BMI<85 percentile, n=58) and obese (85$\leq$BMI, n=41) groups. Subjects were evaluated based on anthropometric measurements, 24-hr dietary recalls and blood analysis. The mean age was 13.93 years. The mean weight (p<0.001), BMI (p<0.001), body fat (p<0.001) of obese were significantly higher then those of normal group. The mean daily energy intake was 94.2% of RDA for Korean. The ratio of energy coming from carbohydrate, fat and protein was 63:24:13. The mean daily intakes of Cu and Zn were 1.4 mg and 7.4 mg (73.7% of RDA), and there were no significant difference between two groups. The mean serum levels of leptin (p<0.001), LDL-cholesterol (p<0.05), triglyceride (p<0.01), TPH (total cholesterol/HDL; p<0.001), LPH (LDL/HDL; p<0.001) and AI (atherogenic index; p<0.001) of obese were significantly higher than those of normal group. The mean serum Cu level of obese was significantly higher than normal group but, the mean serum Zn level of obese was significantly lower than normal group. Serum Cu showed a significantly positive correlations with body weight (p<0.001), BMI (p<0.001), body fat (p<0.001), serum leptin, and LPH. However, serum Zn showed a significantly negative correlations with body weight (p<0.001), BMI (p<0.001), serum leptin (p<0.001), TPH (p<0.05), and AI (Atherogenic index; p<0.05). To summarize the results, the Zn intakes of middle school girls did not reach to RDA for Koreans. Also, increase of BMI may lead to decrease of serum zinc level and increase of serum copper level, and this change of serum zinc related to the change of serum leptin and serum lipids level in middle school girls during rapid growth.

To investigate the effects of isoflavone supplementation on both bone mineral density and hormone variation in premenopausal women who had decreased bone mass, the 24 subjects were divided into two groups: one was the underweight group, consisting of 13 subjects, and the other was the normal weight group consisting of 11 subjects. For each group, we investigated the effects of isoflavone supplementation of 90 mg/day on both bone mineral density and hormone variation during 3 menstrual cycles. Anthropometric measurements, dietary recall, and analyses of blood and urine were assessed from baseline to post-treatment. The results were as follows: The average age of the underweight group was 21.8 years old and that of the normal weight group was 23.2 years old. The comparative results for the two groups at baseline were as follows: Onset of menarche, menstrual cycle, and menstrual length were not significantly different between the groups. Serum protein, total, HDL-, LDL-cholesterol, triglyceride, Ca, P, Mg, Cu, and Zn level were not significantly different between the groups. Serum estradiol, SHBG, LH, and FSH level were also not significantly different between the groups. Lumbar spine BMD by T scores of the underweight group was significantly lower than that of the normal weight group. Serum osteocalcin, urinary DPD, and urinary pH were not significantly different between the groups. The comparative results for the two groups at post-treatment were as follows: From baseline to post-treatment, the intake of energy, nutrients and isoflavone in food did not significantly change in either group. Serum protein, total cholesterol, HDL-, LDL-cholesterol, and triglyceride levels did not significantly change in either group. Serum Ca, Cu, and Zn levels were significantly lower in both groups and serum Mg level significantly decreased only in the underweight group. Serum estradiol levels were significantly lower in both groups, but serum SHBG, LH, and FSH levels did not significantly change in either group. Lumbar spine BMD by T score of the underweight group significantly increased to 15%, but that of the normal weight group did not significantly change. Serum osteocalcin of the underweight group significantly increased to 28%, while that of the normal weight group significantly increased to 40%. Urinary DPD of the normal weight group significantly increased to 12%. The results show that the BMD of the underweight group was lower than that of the normal weight group. Therefore, the underweight group had a disadvantage in obtaining maximum bone mineral density. The results also show that isoflavone supplementation during 3 menstrual cycles was effective in increasing the bone mineral density of the lumbar spine and affected bone metabolism markers in premenopausal underweight women. Therefore, it can be concluded that sufficient intake of isoflavone could be helpful in preventing decreases in bone mass among premenopausal women, especially underweight women.

To determine whether the feeding of different species of hay affects the dry-matter intake and the serum cortisol level of sheep, 6 non-pregnant, non-lactating ewes were offered alfalfa (Medicago sativa) hay (Al), oats (Avena sativa) hay (Ot) and perennial ryegrass (Lolium perenne) hay (Pr) under 6 kinds of treatment including 1) change from Al to Ot, 2) Al to Pr, 3) Ot to Al, 4) Ot to Pr, 5) Pr to Al, and 6) Pr to Ot. The experimental design was a 6${\times}$6 Latin square with a 14 day period of which 9 days were a preliminary period and 5 days as a digestion trial period. The change in hay feeding was done abruptly on the first day of each period without an adaptation period. The blood from the jugular vein was collected on the first, third and the last day of each period through a sterile catheter for the analysis of cortisol. The dry-matter intake was recorded daily throughout the period. The mean daily intake of dry matter (DM, g/kg live weight) was significantly different among the 3 species of hay (Al>Ot>Pr; p<0.05). The digestibility of DM for Al and Ot was the same, but that for Pr was significantly lower than Al and Ot (p<0.05). The mean serum cortisol levels were significantly different among the hays (p<0.05). The level for Pr was the highest and that for Al was the lowest. The abrupt change of hay feeding of 6 treatments produced a significant change in the serum cortisol levels. The DM intake was inversely related to the change of the cortisol level. It is suggested that the animal' intake response to different species of hay may be partly motivated by the psychological feelings toward the hay offered.
