This research was conducted to investigate the performance of a weight control program in university students in Daejeon during 3 months from November 2014 to February 2015. This program measured body measurement and composition analysis, nutritional education, and counseling every month. The status of students' weight control was surveyed before and after the program. The participants were 17 males (24.5 years old) and 15 females (20.8 years old). Their weights before the program were 78.2 kg (male) and 57.2 kg (female), whereas after the program, weights were 77.6 kg (male) and 56.2 kg (female). Weight reduction in students was 53.1%, and weight increase was 40.6% by the weight control program. Body mass index (BMI) tended to decrease after the program. Body fat % and muscle masses were not significantly different by program practice. Body image decision of females showed mainly 'normal' status while that of male was 'over fatty constitution', Before and after the program, the most prevalent method of weight control was exercise for all students. The most selected exercise was 'walking and jogging' during the program. For the most effective weight control method, female acknowledged both 'reducing amount of meals' and 'increasing exercise' while males selected 'increasing exercise.' On the side effects of weight control, over 40% of all students chose 'no experience' and 'loss of volition'. The degree of student's goal achievement was largely 20 ~-20% compared with their goal weights. Accordingly, this program didn't show significant effects. For effective weight control, it is recommended to conduct nutritional education. Students can exercise regularly and control diet to sustain a healthy and satisfactory body status.

The purpose of this study was to know the effect of aquatic-exercise on muscle atrophy which induced by steroid injection. The forty-eight Sparague-Dawley adult male rats were assigned to the 4 groups; Group I (distilled water injection), Group II (steroid injection), Group III (distilled water injection with aquatic exercise), Group IV (steroid injection with aquatic exercise). We observed their body weight, muscle relative weight, myofibrillar protein content. The results of this study were as follows; 1. Body weight was decreased rapidly on steroid injection groups in comparison with distilled water injection groups after 2 weeks (p<0.01), but that was almost recovered as before test on steroid injection group with aquatic exercise. 2. The relative weight of gastrocnemius muscles was decreased on steroid injection groups in comparison with distilled water injection groups. however, Decrease of it on steroid injection group with aquatic exercise for steroid injection group was fallen. There was very significant difference after 4 weeks (p<0.01). 3. Myofibrillar protein content of gastrocnemius muscles was decreased on steroid injection groups in comparison with distilled water injection groups. however, Decrease of it on steroid injection group with aquatic exercise for steroid injection group was fallen. There was significant difference after 4 weeks (p<0.05).

The effect of KTC-1, a new semisynthetic rifamycin antituberculous drug, on general toxicity, reproductive capability and fetal development was investigated in Sprague-Dawley rats. Male rats were administered KTC-1 with mashed feed from 63 days before mating to the end of mating period, and female rats were given from 14 days before mating to day 7 of gestation at dose levels of 0, 375, 750, and 1,500 ppm. The females were sacrificed on day 21 of gestation for examination of their fetuses. At 1,500 ppm, a reduction in body weight gain and testis atrophy were observed in male rats. Histological examination revealed testicular atrophy, absence or decrease of germinal cells, and vacuolization of Sertoli cells in testis. A reduction in body weight gain, a decrease in food consumption were found in female rats. In addition, decreases in the number of corpora lutea, iraplantations, and the litter size of live fetuses were seen. Mating, fertility, and pregnancy performances were also affected. There were no external abnormalities observed by examination of fetuses. At 750 ppm, a reduction in the body weight gain of male and female rats and decreases in the number of implantations and litter size were found. At 375 ppm, no treatment-related effects were observed. The results suggest that the no-effect dose levels (NOELs) of KTC-1 are 375 ppm for males and females on general toxicity, 750 ppm for males and females on reproductive capability, and 375 ppm for fetuses on embryonic development.

The toxicity of DA-125. a new anthracycline anticancer agent, on the male reproductive system was studied in Sprague-Dawley rats. Forty male rats were rando$m\ell$y assigned to Jour groups with ten rats in each group and given single intraveneous doses of DA-125 at dose levels of 0. 12.5. 25. and 50 mg/kg body weight. On day 56 after treatment the animals were allowed to mate. and their male reproductive Junctions and organs were examined in detail. Copulated females were sacrificed on day 20 of gestation for examination of embryo-fetal development. One out of ten rats in the 50 mg/kg group died on day 12 after treatment. Clinical signs such as emaciation. sedation, anorexia. swelling. dark material around eye. alopecia. and diarrhea were observed in the 25 and/or 50 mg/kg groups. Reduction in the body weight gain. decrease in the absolute weights of testes. epididymis and seminal vesicles. and/or decrease in the number of testicular sperm heads were also found. Although histopathological changes such as atrophy of seminiferous tubules. loss or decrease of spermatogenic cells. exfoliation of spermatogenic cells. vacuolization of Sertoli cells. decrease of sperm. and/or increase of necrotic spermatogenic cells in epididymal ducts were observed. no adverse effects on the motility and morphology of epididymal sperm. copulation index. fertility index. and embryo-fetal development were detected in the 25 and 50 mg/kg groups. There were no evidences of male reproductive toxicity in the 12.5 mg/kg group. These results show that single intravenouse doses of DA-125 produce significant dose-related testicular atrophy. histopathological changes. and oligozoospermia in rats and $LD_{10}$ for DA-125 appears to be 50 mg/kg body weight.

This study was to determine the effect of DHEA administration before, during, and after dexamethasone treatment on body weight and TypeI,II muscle weight of rat receiving dexamethasone treatment. Method: Wistar rats were divided into 6 groups: control(C), dexamethasone(D), DHEA administration for 3days after dexamethasone treatment for 7days(7D+3DH), dexamethasone treatment for 7days after DHEA administration for 3days(3DH+7D), DHEA administration during dexamethasone treatment for 4days after dexamethasone treatment for 3days(3D+4DDH), DHEA administration during dexamethasone treatment for 7days(7DDH). Dexamethasone was injected by subcutaneously daily at a dose of 5mg/kg. DHEA was orally administered daily at a dose of 5mg/kg for 7 days. Soleus(TypeI) muscle, and both plantaris and gastro- cnemius(TypeII) muscles were dissected on the 7th day of experiment. Result: Body weight of both 3DH+7D group and 3D+4DDH group increased significantly compared with that of 7D group. Body weight of 7D+3DH group decreased significantly compared with that of 7D group, 7DDH group, 3DH+7D group and 3D+4DDH group. Muscle weight of both plantaris and gastro- cnemius tended to decrease compared with that of 7D group. Muscle weight of 7DDH group, 3D+4DDH group and 3DH+7D group increased significantly compared with that of 7D+3DH group. Muscle weight of gastrocnemius of both 3DH+7D group and 3D+4DDH group increased significantly compared with that of 7D group. Conclusion: Based on these results, it can be suggested that DHEA administration before and during dexamethasone treatment can increase both body weight and mass of atrophied TypeII muscle induced by dexa- methasone treatment.

Objectives: To investigate the weight loss effect of Gambi-tang in obese and overweight adults. Methods: From September 1, 2016 to December 31, 2021, a retrospective chart analysis was conducted on adult men and women who were prescribed Gambi-tang to address obesity and overweight in the National Medical Center (NMC). Partial analysis by age, obesity (Body Mass Index, BMI), duration of dose, and cumulative dose was also conducted. Results: The weight and BMI of the study subjects showed a significant decrease of more than 5% on average before and after treatment. In an analysis of age, significant differences by age could not be confirmed. In the analysis by obesity level, the effect of reducing weight, body fat, and abdominal fat rates in the obese and highly obese groups was greater than in the normal and overweight groups. There was no significant difference by group in the analysis by dosage period. In the analysis by cumulative dose, the greater the cumulative dose up to 1,800 g, the greater the decrease in weight and body fat. The side effect that patients appealed to the most was misjudgment, but not to a serious extent. Conclusions: Gambi-tang has been shown to be effective in weight and body fat loss for both obese and overweight adult men and women.

The purpose of this study was to identify the effect of cerebral ischemia on affected(Lt) and unaffected(Rt) side of soleus, plantaris and gastrocnemius muscle mass and determine the effect of exercise on affected and unaffected side on soleus, plantaris and gastrocnemius muscle mass during acute stage of stroke. Sixteen male Sprague-Dawley rate with 200-270g body weight were randomly divided into three groups: control, stroke, and exercise after stroke(St+Ex) group. The control group received sham operation and the stroke group and St+Ex group received transient right MCA(middle cerebral artery) occlusion operation. The St+Ex groups ran on a treadmill for 20min/day at 10m/min and $10^{\circ}$ grade for 6days. During the experimental period body weight and diet intake was measured every morning. On the 7th day after operation, muscles were dissected from both affected and unaffected side of hindlimb. Cerebral infarction of stroke and St+Ex groups were identified by staining with TCC for 30 minutes. The data were analyzed by Kruskal-Wallis test and Mann-Whitney U test using the SPSSWIN 9.0 program. Significance was accepted at the level of p<0.05. The results were summarized follows : 1) There were no significant difference of the body weight on the first day of experiment among 3 groups. Whereas on the 7th day, the body weight of both stroke group and St+Ex group were significantly smaller than that of control group. Body weight of St+Ex group on the 7th day tended to be larger than that of stroke group. 2) Total diet intake of both stroke group and St+Ex group were also significantly smaller than that of control group. While total amount of diet intake in St+Ex group tended to be larger than that of stroke group. 3) The weight of gastrocnemius muscle of affected side in stroke group significantly decreased compared to that of control group and the weight of soleus and plantaris muscle of affected side in stroke group tended to decrease compared to that of control group. 4) The weight of plantaris muscle of unaffected side in stroke group significantly decreased compared to that of control group and the weight of soleus and gastrocnemius muscle of unaffected side in stroke group tended to decrease compared to those of control group. 5) The weight of gastrocnemius muscle of affected side in stroke group significantly decreased compared to that of unaffected side and there was no significant difference of the weight of soleus and plantaris muscle in stroke group between affected side and unaffected side. 6) The weight of soleus, plantaris and gastrocnemius muscle of both affected side and unaffected side in St+Ex group had a tendency of increase compared to those of stroke group. The relative weight of soleus and gastrocnemius muscle of affected side and soleus muscle of unaffected side in St+Ex group had a tendency to increase compared to those of stroke group. Based on these results, exercise during acute stage of stroke might attenuate muscle atrophy of both affected and unaffected side of hindlimb muscles.

Prevalence of an obese population has been increasing in Korea. Obesity is considered a major risk factor for chronic degenerative diseases. Specifically, prevalence of obesity is prominent for adult woman in Korea. In many weight control programs, weight change did not often show any beneficial effects for health. These facts discourage people in the program. Thus in this study, the anthropometry, blood pressure, serum biochemical indices and dietary habits were compared by percent body fat change for adult women to show the beneficial effects of the weight control program. Study subjects were 134. Measurements were done before and after the weight control program. Percent Body Fat (PBF) was measured by bioelectrical impedance analysis. Using PBF changes, subjects were grouped as I (more than 1% increase), M (${\pm}1%$ change), and D (more than 1% decrease). Data were analyzed using SPSS 12.0 program. Among the 134 participants, 13 increased their weight and 100 decreased. For PBF, 19 increased and 59 decreased. Statistical significant differences were shown for anthropometric assessments before and after for all weight, fat mass, percent body fat, waist-hip ratio and body mass index. I had increases, and D shows decreases. But the difference of D is large than M. Systolic and diastolic blood pressures decreased in all groups (p < 0.05). Fasting blood glucose decreased in all groups but were statistically significant only in D. Also triglyceride decreased in D (p < 0.05). Thus health conditions showed desirable changes in I < M < D in order. Dietary habit changes were desirable with only D. Weight, BMI and other indicators for obesity is not the real indicator for PBF. Recently it is easy to measure PBF. Thus, for weight control programs and to show benefits of the program, PBF is a good indicator for adult women in Korea.
