  • The influences of the mandibular displacement and valium administration on the muscular activity were observed by spectrophotometric analysis of glycogen, glucose, G-6-P, lactate, pyruvate, ATP, phosphocreatine ana protein. Experimental animals were divided into three groups; the first was the mandibular displacement group, the second was valium administered group and the third was the mandibular displacement and valium admministered group. In mandibular displacement group, the high inclined plane with a gap of 2.5mm to 3.0mm between the upper and lower incisors was created by setting the silver crowns on the lower incisors. By creating such a high inclined plane, the bite was opened and the mandible was dispalced posteriorly. In valium administered group, 5mg/kg body weight of valium was administered intraperitoneally every day until the animal was sacrificed. Results were as follows: I) The body weight of all experimental rats was decreased in the beginning of experimental periods. The body weight of the mandibular displacement group showed the similar increasing rate as the control group from 15 days of experimental period. 2) The superficial masseter muscles of the mandibular displacement group appeared to be decreased it's functional activity at 36hrs, 60hrs and 96hrs of experimental periods as revealed by the decrease of various metabolites studied in this experiment. From 96hrs of experimental periods, the contents of those metabolites tended to increase up to the control level. 3) The superficial masseter muscle of 2nd group showed the decreased value of all metabolites at until 60hrs and the values were recovered to almost the same as the control at 168hrs. 4) Glycogen and G-6-P contents induced by mandibular displacement plus valium administration, showed longer duration of the decreased value than 1st group. And the decrease of glucose and pyruvate contents induced by mandibular displacement at 36hrs and 60hrs of experimental periods was enhanced by valium administration. However, the contents of lactate in 3rd group were decreased continuously until the end of experiment.

  • Capsaicin is a pungent component of red pepper, which is widely consumed as food adjuncts. The present study was performed to investigate anti-obesity effects of capsaicin in diet-induced obese rats. Male Sprague-Dawley rats (n=14) were fed with a high-fat diet (Control) or high-fat diet containing 0.016% capsaicin (w/w) (Capsaicin) for 8 weeks. The final body weight and the mass of white adipose tissue were significantly lower in capsaicin supplemented group compared to control. Dietary capsaicin ameliorated lipid profiles with decrease in the plasma concentrations of triglycerides and total cholesterol, and decrease in the levels of total lipids and triglycerides in the liver. Activity of glycerol-3-phosphate dehydrogenase (GPDH), an indicator of triglyceride biosynthesis in white adipose tissue, decreased by 35% in the group supplemented with capsaicin. However, consumption of capsaicin increased the expression of uncoupling protein 2 (UCP2) in white adipose tissue, which is related to energy consumption. Our data suggests that capsaicin may reduce body weight and fat accumulation in high fat diet-induced obese rats. These effects may be mediated, at least partially, by the upregulation of UCP2 gene expression and its ability to inhibit GPDH activity.

  • This investigation was performed to study the antioxidant activities of Hovenia dulcis THUNBER var. koreana Nakai fruits extracts and the effect of Hovenia dulcis fruits extracts on glucose, lipid metabolism in diabetic rats. DPPH free radical scavanging activitiy and superoxide anion radical Scavenging of Hovenia dulcis fruits $80\%$ methanol extracts were $0.06\pm0.002mg$ polyphrnol/ml and $0.l2\pm0.00lmg$ polyphmol/ml, respectively. Hovenia dulcis fruits $80\%$ methanol extracts were partitioned into hexan, dichloro methane, ethyl acetate and butanol, successively. Ethyl acetate fraction were good antioxidant activity. Streptozotocin (45 mg/kg body weight, i.p.) induced diabetic rats showed a significant increases of plasma glucose, triglyceride and total cholesterol. Concomitantly significant decrease of plasma high density lipoprotein. Glutathione level were decrease in cytosol of liver. Lipid peroxide were increase in microsome of liver. Group 1 and 2 were treated with Hovenia dulcis fruits ethyl acetate extracts 50 mg/kg body weight and 20mg/kg body weight for 24 days, individually. Group land 2 rats showed decreased plasma glucose, triglyceride, total cholesterol and lipide peroxide in microsome of liver tissue of rats, and increased plasma high density lipoprotein and glutathione in cytosol of liver tissue rats. The result suggest that Hovenia dulcis THUNBER var. koreana Nakai fruits extracts may effectively normalize the impaired antioxiants status in streptozotocin induced diabetic rats. Hovenia dulcis fruits ethyl acetate extracts were used to improve the imbalance between free radicals and antioxidant system due to the diabetes.

  • This study was conducted to determine the effects of chromium-methionine (CrMet) supplementation at various levels on obesity index, body fat, and serum glucose, insulin and leptin in rats. Forty male Sprague-Dawley rats were randomly assigned to one of four dietary groups and fed AIN-76 semi-purified basal diets supplemented with 0, 300, 600 or 1200 ppb Cr from CrMet. After 4 weeks on the respective diets, the rats were killed and serum glucose, insulin and leptin concentrations were determined. The CrMet supplementation did not affect weight gain, feed intake or feed efficiency ratio, fasting glucose, insulin or leptin levels among treatment groups. Although final body weight in all treatments were not significantly different, naso-anal length was longer in the 1200 ppb CrMet group than those of control or other groups (p<0.05). The lowest obesity index and body fat were observed in the 1200 ppb dietary group (p<0.05). The obesity index of the rats fed 1200 ppb supplemental CrMet was lower than in the other groups. These results suggest that CrMet supplementation results in a significant decrease in obesity index, possibly by decreasing the body fat that corresponded to increasing CrMet dosage.

  • In this study, we compared demographic anthropometric characteristic, health-related lifestyle and diet behavior among weight control behaviors of 1187 (555 male, 632 female) aged $40{\sim}69yrs$ in Ganghwa country. All the data were analyzed by chi-square test, trend test, student t-test using SPSS 12.0 version at p < 0.05. 'Attempting weight control (loss)' was more in women than that was found in men (36.6% vs 20.7%), and women attempting weight loss most were 40-50 yrs. The reasons of weight loss were 'health problem' and 'health promotion'. Physical activity and diet restriction were commonly employed as weight control methods. Both genders attempting weight loss had a higher education level, BMI, percentage of body fat, waist circumference and physical activity than those not attempting weight control (p < 0.05). In dietary habits like 'meal regularity', 'slow eating' and 'over eating', women attempting weight loss were superior than those who not attempting weight control group (p < 0.05). Eating pattern changes like 'decrease of fats and fatty foods intake', 'vegetable oil usage', 'increase of fruit and vegetables intake', 'decrease of sugar and salt intake' showed significant differences (p < 0.001) between the attempted weight control groups and nonattempted weight control groups. Salt taste was a preference in male non-attempted weight control group, while sour, hot and spicy taste were preference in female attempted weight control group (p < 0.05). Preference for processed foods, fried foods and snack were significant differences (p < 0.05) in women attempted weight control group. Those attempting weight loss tried to improve their eating patterns. However, those attempting weight loss were poorer than the others in health-related lifestyle and eating habit. Therefore, it is necessary to make an effort that improve healthrelated lifestyle and diet behavior in middle aged group.

  • To obtain the 50% lethal dose (LD50), approximated lethal dose (ALD) and approximated target organs of 'Mahwangyounpae-tang' for further study like repeat dose toxicity, genotoxicity and reproductive toxicity, single dose toxicity was tested in male ICR mouse according to KFDA Guideline 1999-61 [KFDA, 1999] at a dosage level of 2,000, 1,000, 500, 250 and $125\;mg/kg/10m{\ell}$. In this study, mortalities, clinical signs, body weight changes and body weight gains, gross findings and weight of principal organs were detected during and/or after 14 days of single dosing. After 2 or 3 days of dosing, 1 or 2 animals in 2,000 and 1,000 mg/kg-dosing groups were died. Excitation and leaping response were observed as test article-treatment related clinical signs. These abnormal signs were restricted to 2,000 and 1,000 mg/kg-dosing groups and they were recovered to normal within 4 days after dosing in case of survivors. A significant decrease of body weight were observed in some periods of observation in 2,000 and 1,000 mg/kg-dosing group from 1 days after dosing compared to those of vehicle control group. A significant decrease of body weight gains were observed in observation periods in 2,000 and 1,000 mg/kg-dosing group compared to those of vehicle control group. Hypertrophy of heart and decoloration of kidney were observed as test article-treatment related gross findings. These abnormal findings were restricted to 2,000 and 1,000 mg/kg-dosing groups. A significant increase of absolute and relative heart and kidney weight were demonstrated in 2,000 mg/kg-dosing groups. LD50 in this study was detected as 2,242.42 mg/kg. ALD in this study was detected as 1,000 mg/kg and the target organ was considered as the heart and kidney.

  • In order to study the effects of administration of neomycin on the kidney of Korean black goats, 4.5(group A), 9(group B) or 14(group C) mg/kg, body weight of neomycin was injected intramuscularly turice a day for 84 days. On day 31, unilateral nephreotomy was performed in one animal of each group. The results were as follows: Serum neomycin concentrations were 8.7, 13.8, and 20.2 ${\mu}$g/ml 12 hours after injection. Serum BUN and creatinine concentration in nephreotomized goats, regardless of dosage, rapidly increased and came to peak on 3 days after, and then began to decrease to normal range, gradually, In non-nephrectomized goats, regardless of dosage, there was no notable change. In nephreotomized goats, PSP Tl/2 was delayed to the utmost 1 day after nephrectomy, regard-less of dosage, and then began to decrease to normal range, gradually in non-nephrectomized goats, there was not notable change in PSP T$\frac{1}{2}$. The intact kidney was markedly enlarged compared with the kidney of non-nephrectomized goats, but there was no microscopic change. It is concluded that administration of neomycin up to 14mg/kg body weight twice a day for 84 days was not nephrotoxic to the Korean black goats.
