The purpose of this study is to investigate the relative influence of diet and physical activity on obesity. The subjects were 155 adults aged 35-52 years from 24 neighborhood committees in 4 urban districts of Beijing (male : 78, female : 77). They were divided into normal weight, overweight and obese groups according to their BMI. The general information of the subjects was collected by interview-administered questionnaire. Dietary intake was obtained by three-day(two weekdays and one weekend day) food weighted method, physical activity was assessed by a validated combination of data obtained from activity monitors, bicycling information and activity records. There were no significant differences of age, gender, height, educational, family economic level, smoking and drinking between different groups. The proportion of flour intake was higher in obese group compared to normal weight and overweight groups, and that of vegetables is lower in obese group. The physical activity (PAL) was not significantly different between two groups of the normal, overweight and obese groups. After the adjustment for confounding factors using logistic regression model, we found that the proportion of flour intake was positively associated with obesity, while the proportion of vegetable intake was inversely associated with obesity. It is concluded that dietary patterns were associated with obesity and diets composed of more vegetables and less staple combined with physical activities could contribute to obesity prevention.
To evaluate the effect of ground cherry extract on the activity of aniline hydroxylase, we gave ground cherry extract in doses of 100, 200 or 400 mg/kg i.p to mice for 1, 2 or 4 days. The aniline hydroxylase activity in the group treated with ground cherry extract increased in a dose dependant manner in all experimental groups compared with the control group, and was significantly higher in the group treated with ground cherry extract at a dose of 200 mg/kg, which also exhibited a time dependant increase over 4 days. Enzyzme kinetic analysis was performed for hepatic aniline hydroxylase activity in the group treated with 200 mg/kg for 4 days. There was no change of the Km values for aniline hydroxylase between the experimental group and the control group, but the Vmax values for aniline hydroxylase was 21% lower in the experimental group compared with the control. The experimental group also showed lower lipid peroxide and reduced glutathione content, and there were no significant difference in serum alanine aminotransferase activity between the experimental group and the control. Aniline was injected into both the experimental group mice treated with ground cherry extract at a dose of 200 mg/kg for 4 days and the control group, and then the level of blood aniline was assayed at 1hr. The level of blood aniline was lower in the experimental than the control group. This study suggests that ground cherry extract induces hepatic aniline hydroxylase activity and might accelerate the scavenging system of reactive oxygen species. It is likely that ground cherry extract influences the metabolism of xenobiotics by activating AH activity substituted for CYP2E1.
Bobitang(BBT) is one of the most important prescription that has been used in oriental medicine(dongyibogam) for recovering spleen condition. The study was done to evaluate effects of BBT water extract on the spleen lipid peroxide content and metabolic enzyme system changes. After pretreatment of BBT I (100mg/kg), BBT II(250mg/kg), BBT III(350mg/kg), BBT IV(500mg/kg) for 1 week, lipid peroxide content and metabolic enzyme system changes of the spleen was measured in 8 months rats. The results were obtained as follows : 1. The content of spleen lipid peroxide was significantly decreased in all experimental groups as compared with control, and best in BBT III IV treated groups. 2. The activity of spleen superoxide generation was significantly decreased in all experimental groups as compared with control, and best in BBT IV III treated groups. 3. The activity of cytochrome P-450 and aminopyrine demethylase wasn't significant change. 4. The activity of aniline hydroxylase was significantly decreased in BBT IV II treated groups, xanthine oxidase was significantly decreased in all experimental groups, aldehyde oxidase was significantly decreased in BBT IV treated group as compared with control. 5. The activity of antioxidant enzymes as superoxide dismutase, catalase, glutathione peroxidase was significantly increased in all experimental groups as compared with control. 6. The activity of glutathion S-transferase was significantly increased in all experimental groups, the concentration of spleen glutathione was significantly increased in BBT IV treated group as compared with control. 7. The activity of ${\gamma}$ -glutamylcystein synthetase was significantly increased in BBT III IV I treated groups as compared with control, the activity of glutathione reductase wasn't significant change. From the above results, BBT is cosidered to have effect of remove peroxide content and free radical that was made during ageing process. It is expected that treatment of BBT can be applied in future clinical study of delaying the ageing process.

Background: This study investigated the effect of robot-assisted arm training on muscle activity of arm and weight bearing in stroke patients. Methods: The study subjects were selected 20 stroke patients who met the selection criteria. 10 people in the robot-assisted arm training group and 10 people in the task-oriented arm training group were randomly assigned. The experimental group performed robot-assisted arm training, and the control group performed task-oriented arm training for 6 weeks, 5 days a week, 30 minutes a day. The measurement tools included surface electromyography and smart insole system. Data were analyzed using independent sample t-test and the paired sample t-test. Results: Comparing the muscle activity of arm within the group, the experimental group and the control group showed significant differences in muscle activity in the biceps brachii, triceps brachii, anterior deltoid, upper trapezius, middle trapezius, and lower trapezius. Comparing the muscle activity of arms between the groups, the experimental group showed significant difference in all muscle activity of arm compared to the control group. Comparing the weight bearing within the groups, the experimental group showed significant difference in the affected side and non-affected side weight bearings and there were significant differences in anterior and posterior weight bearing. The control group showed significant difference only in the non-affected side weight bearing. Comparing the weight bearings between groups, the experimental group showed significant difference in the affected side and non-affected side weight bearings compared to the control group. Conclusion: This study confirmed that robot-assisted arm training applied to stroke patients for 6 weeks significantly improved muscle activity of arm and weight bearing. Based on these results, it is considered that robot-assisted arm training can be a useful treatment in clinical practice to improve the kinematic variables in chronic stroke patients.

The effects of prochloraz on membrane permeability and germination of uredospores of Puccinia recondita were investigated to determine its potential mode of action on wheat leaf rust control activity. Disease control activity of ergosterol biosynthesis inhibitors (EBIs) and their activities on uredospore membrane permeability and germination were examined with wheat leaf rust pathogen, both in vitro and in vivo. While wheat leaf rust was not controlled by prochloraz, electrolytic leakage and spore germination of P. recondita uredospore was the highest with the use of prochloraz among the eight fungicides tested. Prochloraz stimulated uredospore of P. recondita to germinate at a higher ratio. Although certain EBIs, such as hexaconazole, showed excellent control activity, their effects on uredospore membrane permeability and germination was much inferior to prochloraz. Therefore, results of this study suggest that effects of EBIs on membrane permeability and germination of uredospore are not always correlated with their disease control activity.
Background: This study aimed to investigate hyperuricemia, renal inflammation, and xanthine oxidase (XO) activity improvement in a rat model treated with Scutellaria baicalensis extract (SBE). Methods: The rats were divided into 4 groups (n = 5 each), including sham, potassium oxonate (PO) injected hyperuricemia (control group), PO + 10 mg/kg allopurinol administrated (allopurinol group), and a PO + 50 mg/kg SBE administrated (SBE group), to investigate the effectiveness and molecular mechanisms of SBE. The effects of SBE on PO-induced hyperuricemia rats, renal inflammation, and XO activity were measured. Body weight and organ index of the kidney and liver were measured in PO-induced hyperuricemia rats, and serum uric acid level was extracted from whole blood and was measured. Renal inflammation was observed under a microscope after sections. XO activity was measured by liver tissue and serum XO levels. Results: Organ indexes of the kidney and liver in rats were significantly decreased in the allopurinol group than in the control group and with no significant difference in the SBE group. A PO injection for 5 days significantly increased serum uric acid levels in the control group compared to the sham group. Meanwhile, the SBE and allopurinol groups have significantly decreased serum uric acid levels compared to the control group. The SBE group revealed effectively improved renal histopathological changes compared to the control group. The XO inhibitor, allopurinol, significantly decreased XO activity. Additionally, SBE significantly lowered XO activity in rats. Conclusion: SBE can be used as an effective treatment for gout in the future.
Lipid lowering properties from three plant water extracts, Rosa rugosa, Crataegus pinnatifida and Polygonum cuspidatum, were tested by supplementing a 1% high-cholesterol diet with them in rats. Plasma triglyceride levels in Rosa fugosa, Crataegus pinnatifida and Polygonum cuspidatum groups were significantly lower compared to that of the control. by 29% , 24% and 47% respectively. hepatic trigylceride levels in Rosa rugosa and Crataegus pinnatifida groups were significantly lower compared to the control by 11% and 15% respectively. Hepatic HMG-CoA reductase activity in Rosa rugosa group was significantly greater compared to the control by 406%. Hepatic ACAT activity was significantly lower in Polygonum cuspidatum group compared to the control by 28%. by multiple regression results, only plasma cholesterol was associated significantly (p<0.05) with liver HMG-CoA reductase activity. Plasma cholesterol explained 12% of thevariance of the liver HMG-CoA redctase activity. In conclusion, we have showen that hot water extracts from Rosa rugosa, Crataegus pinnatifida and Polygonum cuspidatum lowered plasma triglycerides in rats fed on a high-cholesterol diet. Data suggests that these extracts could potentially prevent or treat hypertriglyceridemia induced by a high fat diet and fatty liver.
Recently, strains of methicillin-resistant Staphylococcus aureus (MRSA) with reduced susceptibility to vancomycin (VCM) have been clinically isolated. The antibacterial activity of a new drug, linezolid (LZD), in such a strain was evaluated by measuring bacterial metabolic activity. A total of 73 MRSA strains having various susceptibilities to VCM were subjected to a novel and highly sensitive chemiluminescence-based assay. LZD MIC in the tested strains, measured by the microbroth dilution method, was within the range 1-4 mg/l (mostly ${\leq}2$mg/l), except for one LZD-resistant strain (NRS127; MIC=7 mg/l), and showed no correlation with VCM resistance. The chemiluminescence assay demonstrated that bacterial metabolic activity was strongly suppressed with increasing LZD concentration. The chemiluminescence intensity curve had a low baseline activity without tailing in most strains. The present results suggest that LZD has strong antibacterial activity against MRSA strains, and would be effective for treatment of infections that are poorly responsive to VCM. The chemiluminescence assay facilitated sensitive and discriminative susceptibility testing within a relatively short time.
This study has been attempted to set up the strategies of the nursing which can promote the activity performance for early rehabilitation for the patients by examining the effect of the structured patient education on the early rehabilitation knowledge and activity performance of the C.V.A patients. The study method has been done by investigating the experiment group and control group in advance through the question papers and interview and observation on 65 patients who had been hospitalized at oriental medicine hospital of K Medical Center from July 1st 1995 to the end of Sep, 1995. The analysis of the collected material had been done for the homogeneity test in which general characters of experiment group and control group had been tested by X²and the homogeneity test of ADL by t-test. To test the hypothesis the t-test had been given for the difference of the early rehabilitation knowledge and activity performance between the two groups and the correlation between early rehabilitation knowledge and activity performance had been tested by Pearson's Correlation Coefficient. The result of the test of the hypothesis is as the below. 1 The 1st hypothesis “The experiment group which had received the structured education should be higher in the early rehabilitation knowledge than the control group” was supported(t=4.45. p=.000). 2. The 2nd hypothesis “The experiment group which received the structured education should be higher in the early rehabilitation activity performance than the control group”was supported(t=2.11, p=.036). 3. The 3rd hypothesis “The higher the early rehabilitation knowledge of the patient the higher the activity performance degree” was rejected (r=.1546, p=.219). In conclusion, the patients who received the structured education showed the increase in the degree of early rehabilitation knowledge and activity performance, so it has been judged that education has been prerequisite in increasing the knowledge and activity performance of early rehabilitation.
