A newly synthesized thiazolodinedione derivative, CKD-501, was confirmed to have antihyperglycemic effect in in vivo study. The present study was undertaken to investigate the effect of CKD-501 on glucose transport and its stimulating mechanism in L6-myotubes. L6-myoblasts were cultured and differentiated to myotubes by reducing serum concentration in media from 10％ to 2％. (omitted)

Cadmium is well known as a toxic metal and has insulin mimicking effects in rat adipose tissue. To investigate the effect of CdCl2 on glucose transport and its mechanism, this study was performed in 3T3-L1 adipocytes. 10 and 25mM of CdCl2 exposed to cells for 12 hours increased 2-deoxyglucose uptake to 2.2 and 2.8 fold, respectively. Nifedipine, a calcium channel blocker, inhibited the 2-deoxyglucose uptake stimulated by CdCl2. (omitted)

The study investigated the hygienic practice attitudes of 500 housewives living in the Seoul area through survey. The suey questionnaire evaluated general information, purchasing behaviors, 4 parts of hygienic practice attitude and the associated factors. The subjects were mostly full-time housewives aged in their $30{\sim}40's$, high school graduates from middle-class families who had been married for $6{\sim}10$ years. The mean score for hygienic practice attitude was 2.9 out of 5 point scale, representing a fairly low hygienic practice attitude except for food preparation area(3.4 pt.). Factors affecting hygienic practice attitude were age, occupation, and marriage term. Practice attitude was positively correlated with age (p<0.01). Full-time housewives had better practice attitude. Housewives with <5 and >26 years of marriage showed inferior practice attitude (p<0.05). In addition, food purchasing behaviors were strongly related to hygienic practice attitude. Housewives gathering hygiene information from mass media maintained a significantly higher practice attitude (p<0.05), and so did the housewives focusing on 'nutrition' and 'freshness' when fish and frozen foods were purchased (p<0.05). In contrast, housewives focusing on cost had a significantly lower practice attitude (p<0.05). In conclusion, the level of hygienic practice attitude of housewives was fairly low and was affected by age, occupation status, marriage term and several aspects of purchasing behaviors. Therefore, it is extremely important to conduct training and education for housewives to improve their hygienic practice attitude and awareness of hygiene.

Hangover is associated with ethanol metabolism in body after the ingestion of an alcoholic beverage. Especially. The metabolism in liver is forcused by many researcher because, alcohol (approximately 90％) is metabolized by the liver. Ethanol metabolism in liver involves both liver alcohol dehydrogenase(ADH) which actalyzes the oxidation of ethanol to acetaldehyde, and liver aldehyde dehydrogenase(ALDH) which metabilized rapidly acetaldehyde, product of ethanol oxidation, to acetate.

Hygienic Science is the science for the maintenance and the improvement of human health. Every investigation of hygienic science is originated from practical human life and the fruits of every studies should be recovered and utilized finally by social life. The planning, implementation, evaluation must be carried out by unbiased idea in view of four main aspects in Fig. 1. In the center of that figure you can put any problems that you concern if it is related to health sciences. Today. I want to mention the problem in food and environmental contaminants, referring to some recent status of may country.

Hygienic behavior of Honey bees, Apis mellifera, was evaluated by uncapping and removing ability of dead broods from the nest. Hygienic behavior is originated from quantitative traits, which are expected to express key roles in colony defense against mite parasites and bacterial and fungal diseases. It is regarded as one of important characteristics of honey bee's resistance to parasites and pathogens. In this study, five inbreed and two hybrid lines of A. mellifera, the former five inbreed lines, which have been reared for over eight years at the National Academy of Agricultural Science in Korea, and the latter two hybrid lines, which have been bred by crossing between the inbreed lines, were investigated on their hygienic behavior by a pin-killed brood assay at 12hrs and 24hrs after treatment. The results indicated that after 12hrs one inbred line was proved to be hygienic (removal rate of dead brood >90%), three inbred and two hybrid lines showed intermediate behavior, and one inbred line belonged to non-hygienic (removal rate of dead brood <70%). However, after 24hrs, only one line was considered to be intermediate as removal rate was below 90%, thus all except this line had shown hygienic behavior.

In this study we investigated the effect of hydroxybrazilin on glutathione depletion induced by BrCCl$_3$ and menadione in cultured hepatocytes to understand the cellular mechanisms of hepatoprotective effect of hydroxybrazilin. Hydroxybrazilin alone had no effect on total glutathione level and the ratio of reduced glutathione/total glutathione (GSH/(GSSG+GSH)). BrCCl$_3$ dramatically decreased total glutathione level and hydroxybrazilin significantly prevented glutathion depletion by BrCCl$_3$. The ratio of GSH/(GSSG+ GSH) was also decreased by BrCCl$_3$ and recovered by hydroxybrazilin treatment. Menadione decreased total glutathione level and the ratio of GSH/(GSSG+GSH) but hydroxybrazilin showed no significant effects on menadione-induced glutathione depletion. These data suggest that hydroxybrazilin might prevent the hepatotoxicity induced by chemicalderived radicals but not the toxicity linked with oxidative stress.

The objective of this study was to investigate the effect of the perceived importance of kitchen equipment and facilities on the hygienic performance of cooks in deluxe hotels. Cooks and chefs at 7 different deluxe hotels participated in this study. Out of 490 questionnaires administered, 456 (93.1%) were completed and 419 (91.9%) were analyzed using a statistical package SPSS 12.0. The results were as follows. First, the correlation between sanitary equipment, including HACCP system, in the hotel kitchens and the hygienic management performance confirmed the significant effect of the sanitary equipment on the performance of the cooks and chefs. Second, the sanitary facilities in the hotel kitchens greatly affected the hygienic management performance. The results also demonstrated that the sanitary equipment provided the same contribution to the performance irrespective of the job level, management type and HACCP practice. However, the sanitary facilities greatly affected the management type expecially the chain hotels. The hygienic management performance did not affect the cooking stage (before-cooking and during-cooking), but affected the after-cooking stage according to the management type and the HACCP practice, but not the job level.

The purpose of this study is to develop a diaper hygienic care education program for caregivers and to investigate the effects of the diaper hygienic care knowledge and performance ability on diaper hygienic care. A quasi-experimental research with nonequivalent control group pretest-post test design was conducted. The subjects for the study 50 caregivers working in long-term care facilities in Y-gun, Chungcheongnam-do were selected from the 25 experimental group and the 25 control group. The collected data were analyzed using SPSS Window 22 version. diaper hygienic care education program consisted of 4 sessions in total. According to results of the education program, the diaper hygienic care knowledge increased after the post-test($M{\pm}SD=4.88{\pm}0.23$) compared to the pre-test score($M{\pm}SD=4.64{\pm}0.23$), but not be statistically significant between the two groups(t = 1.253, p = .216). The performance ability of diaper hygienic care was significantly increased ($M{\pm}SD=2.89{\pm}0.15$) compared to the pre - score($M{\pm}SD=1.86{\pm}0.18$) and there was a statistically significant difference(t = 12.694, p =. 001). Thus, the developed diaper hygienic care education program is expected to contribute to improve nursing hygienic care ability of nursing caregivers.
