The present study analyzed the consumer acceptance of labels, satisfaction with cosmetics after purchase, the relationship between consumer acceptance of cosmetics labels and satisfaction with cosmetics as viewed by type of distribution channel. The study was implemented through a descriptive survey method based on a self-administered questionnaire. The sample consisted of 759 women between the ages of 21 and 49, residing in the area of Seoul, Gwangju, and Gyeonggi Province. There were significant differences in the levels of consideration of labels among consumers from each type of distribution channel. Consumers that prefer door-to-door sales consider the information about ingredients more crucial than consumers who prefer other types of distribution channels, department store consumers consider manufacturer information more important, and consumers who prefer specialty stores/chains and discount stores consider the date of manufacture less important than other types of distribution channels. Significant differences were found in consumer satisfaction with cosmetics after purchasing among consumers from each type of distribution channels. A significant relationship was found between the level of considering the product information listed on the labels and the satisfaction with the cosmetics. With respect to most of the factors, a higher level of label consideration was correlated with a higher satisfaction with cosmetics after purchase.

Background: Sox 9 is a major marker of chondrocyte differentiation. When chondrocytes are cultured in vitro they progressively de-differentiate and this is associated with a decline in Sox 9 expression. The active form of vitamin D, 1, 25 $(OH)_2D_3$ has been shown to be protective of cartilage in both humans and animals. In this study equine articular chondrocytes were grown in culture and the effects of 1, 25 $(OH)_2D_3$ upon Sox 9 expression examined. The expression of the transient receptor potential vanilloid (TRPV) ion channels 5 and 6 in equine chondrocytes in vitro, we have previously shown, is inversely correlated with de-differentiation. The expression of these channels in response to 1, 25 $(OH)_2D_3$ administration was therefore also examined. Results: The active form of vitamin D (1, 25 $(OH)_2D_3$ when administered to cultured equine chondrocytes at two different concentrations significantly increased the expression of Sox 9 at both. In contrast 1, 25 $(OH)_2D_3$ had no significant effect upon the expression of either TRPV 5 or 6 at either the protein or the mRNA level. Conclusions: The increased expression of Sox 9, in equine articular chondrocytes in vitro, in response to the active form of vitamin D suggests that this compound could be utilized to inhibit the progressive de-differentiation that is normally observed in these cells. It is also supportive of previous studies indicating that $1{\alpha}$, 25-dihydroxyvitamin $D_3$ can have a protective effect upon cartilage in animals in vivo. The previously observed correlation between the degree of differentiation and the expression levels of TRPV 5/6 had suggested that these ion channels may have a direct involvement in, or be modulated by, the differentiation process in vitro. The data in the present study do not support this.

The present study designed to investigate whether hwangryunhaedok-tang show an anti-hypertensive effect and elucidate its possible mechanism in spontaneously hypertensive rats. The systolic blood pressures (SBP) were significantly decreased as an oral administration of hwangryunhaedok-tang compared with their control group. The urine volume was significantly increased by administration of hwangryunhaedok-tang but urinary sodium (UNaV), potassium (UKV), chloride excretion (UCIV) were not remarkably affected. The urinary creatinine excretion rate (UcrV) was significantly increased in rats administered with hwangryunhaedok-tang in association with increase of creatinine clearance (Ccr). The urine osmolality (Uosmol) was significantly decreased in SHR administered with hwangryunhaedok-tang without being changed in solute-free water reabsorption ( TcH20). The expressions of Aquaporin 2 (AQP-2). 3 and ${\alpha}\;1$, ${\beta}\;1$ subunits of Na.K-ATPase were determined by Western blot analysis to assess the role of these proteins in association with changes of renal functions in SHR administered with hwangryunhaedok-tang. The expression of AQP-2 and 3 protein was significantly down-regulated in the kidney of SHR administered with hwangryunhaedok-tang compared with those in control rats without being altered expression of ${\alpha}\;1$, ${\beta}\;1$ subunits of Na,K-ATPase. In the in vitro assay, Angiotensin converting enzyme (ACE) was inhibited by hwangryunhaedok-tang in a dose-dependent manner. Berberine and/or palmatine, which are well known as a main components of hwangryunhaedok-tang, also have an ACE inhibitory effects in a dose-dependent manner. Taken together, these results suggest that hwangryunhaedok-tang lowered blood pressure through the increase of diuresis caused by down-regulation of water channels and the inhibition of Angiotensin converting enzyme.

Objectives : It has been reported that the presence of a pharmacologically inactive foreign substance, polystyrene latex bead, in subarachnoid space activates a non-specific immunological response and elicits arterial narrowing. Recently the activation of potassium($K^+$) channels may be of benefit in relieving cerebral vasospasm. The present study examined the effects of systemic administration of a ATP-sensitive $K^+$ channel activator, cromakalim, on the polystyrene latex bead-induced cerebral vasospasm. Methods : The spasm models similar to that caused by subarachnoid blood injection were created by injection of bead into rabbit cisterna magna. Intravenous injections of cromakalim were administered twice daily(bid) 30 minutes after induction of vasospasm. Animals were killed by perfusion-fixation 2 days after vasospasm. Basilar arteries were removed and sectioned, and the luminal cross-sectional areas were measured. Results : Injection of bead elicited an arterial constriction, reducing arterial diameter to 33.3% of resting tone. Cromakalim inhibited bead-induced constriction at a dose of 0.3mg/kg(Mann-Whitney test, p<0.01). Conclusion : These results support the concept that the cellular events triggered by inactivation of ATP-sensitive $K^+$ channels are responsible for the pathogenesis of vasospasm. The findings also indicate that cromakalim represents a potential therapeutic agents for the treatment of cerebral vasospasm.

The purpose of this study was to examine the recognition about food preparation and cooking ability of college students majoring in food & nutrition and others. Data were collected from 729 students residing in Chonbuk area by using a self-administered questionnaire. Food and nutrition major students got significantly higher scores than non-major. ones in the recognition of significance and interest in cooking activity. Both food and nutrition major and non-major female students recognized the necessity of cooking ability than non-major male students. Sixty eight percent of the subjects answered that they have aided often his or her family to cook at home. The students majoring in food and nutrition were interested in various fields such as Korean, western style and fusion food. Most of the respondents teamed how to cook from family at home; however major students have learned cooking not only from family but also from various channels such as culinary school, TV and books. The practical use of knowledge about food science was very low in most respondents. The cooking methods used frequently were sauteing, broiling and deep-fat-frying. This study showed that both food and nutrition major and non-major students recognized the necessity of cooking ability and had interests in cooking activity, but cooking ability of non-major ones was significantly lower than that of major students, and the traditional consciousness that women have to take charge of cooking at home tends to be decreasing.

Purposes： The purposes of this study were to investigate the smoking cessation counselling activities among community health practitioners(CHP) and to identify the predictors of their smoking cessation counselling activities. Method： A descriptive-correlation study using self-administered questionnaires was conducted. Questionnaires were mailed to all the CHP in a community. A total of 330 CHPs participated in this survey. Results： Of the CHPs surveyed, 245(74.2％) returned completed questionnaires. Most CHPs(90.7％) believed that if a health professional advises their patient to quit, the patient's chances of quitting smoking are increased. While the majority of CHPs “asked, advised, and assessed” their clients, a minority of CHPs “assisted, arranged, and recorded”. In the final stepwise multiple regression model, attitude about smoking cessation policies and counselling activities, self-efficacy of smoking cessation counselling knowledge and skills, and perceived barriers of smoking cessation counselling activities were identified as significant predictors of smoking cessation counselling activities among CHPs. Conclusion： Smoking cessation counselling activities are not a routine part of CHP practice. Efforts should be made to increase the self-efficacy of smoking cessation counselling knowledge and skills among CHPs. Helping CHPs to overcome their barriers to smoking counselling may open up new channels for smoking intervention.
