The purpose of this study was to examine the housewives' leisure activity and leisure life satisfaction. This study analysed the effects of socio-demographic and economic variables on the housewives' leisure activity. For these purpose, questionnaire was given to the 316 housewives who were lived in Pusan. The data were analysed by Frequency, Percentage, Mean, ANOVA, T-test, Pearson's Correlation and Multiple Regression Analysis. The main findings of the research are as follows: 1. Leisure activities are classified in physical, children and social concerned, self-developing, restful, religious-social, home-oriented, time-spending by factor analysis. The level of average participation are high in time-spending type, but low in self-developing type. 2. There are significant differences in participation level of leisure activities according to related variables. Physical and children-concerned type shows significant differences by age of housewife's education level, income and houses type. Self-developing type differs by husband's occupation, housewife's education level and income. Restful and time-spending type are differed to age of housewife, age of the youngest child and housewife's education level. 3. Leisure life satisfaction shows significant differences by employment type. Fulltime housewives are more satisfied than working housewives. 4. Leisure life satisfaction is high when participation level is high in children-concerned, self-developing, religious-social type and employment type. But leisure life satisfaction is low when preference level is high in self-developing type. The results of this study show the housewives' leisure activity and leisure life satisfaction differ by related variables. For further study and practice, I suggest politic development of leisure programs and increase the level of housewives's life satisfaction.

The present study was undertaken to investigate the effects of age on angiotensin II (AII) response and antagonistic activity of losartan using aortic rings and liver homogenates from rats ranging in age from 0.7 to 20 months. Whether the endothelium was present or not, the maximum contractile response to AII decreased with age. Removal of the endothelium enhanced AII-induced maximum contraction and these endothelial effects seemed to be due to endothelium-derived relaxing factor (EDRF) in all ages. Equilibrium binding studies demonstrated an age-related decrease in maximum binding $(B_{max})$ with little change in binding affinity $(K_d)$. In rat aorta, the extent of losartan-induced parallel shifts $(K_B)$ in AII concentration-response curves was not significantly different between ages. In addition, $IC_{50}$ value of losartan in competition binding was not changed with age in rat liver homogenates. These results suggest that the potency of losartan is not altered with age in rat aorta and liver, although AII-induced contractile response and the maximum AII binding decreased significantly with age.

Preciously, we demonstrated that a novel NHE-1 inhibitor, KR-33028 attenuated cortical neuronal apoptosis induced by glutamate. In the present study, we investigated the signaling mechanism of neuroprotective effect of KR-33028 against glutamate-induced neuronal apoptosis, especially focusing on mitochondrial death pathway. Our data showed that glutamate induces a biphasic rise in mitochondrial Ca2+ and that KR-33028 signifi cantly prevents the second phase increase, but not the fi rst phase increase in mitochondrial Ca2+. Furthermore, KR-33028 restored the ΔΨm dissipation and cytochrome c release into cytoplasm induced by glutamate in a concentration-dependent manner. The inhibition of mitochondrial Ca2+ overload by ruthenium red also inhibited glutamate-induced apoptotic cell death, mitochondrial membrane potential, ΔΨm dissipation and cytochrome c release. These data suggest that inhibition of mitochondrial Ca2+ overload is likely to be attributable to anti-apoptotic effect of KR-33028. Taken together, our results suggest that anti-apoptotic effects of NHE-1 inhibitor, KR-33028 may be mediated through maintenance of mitochondrial function.

Background : Garlic is one of the important vegetables and a source of natural anti-oxidants. This study was carried out to investigate the antioxidant activities including 2,2-diphenyl-1-picr yl-hydrazil (DPPH), 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS), ferric reducing antioxidant power (FRAP), reducing power (RP) and total polyphenol content (TPC) of A. ampel oprasum L. Methods and Results : DPPH, ABTS, FRAP, TPC, and RP were analyzed the extract of aerial plant part in 22 accessions of A. ampeloprasum by spectrophotometry mathod. A. tuberosum Rottler ex Spreng. was used as a control. DPPH was ranged from 0.35 to 3.06 ㎍ ASC ㎎-1 dw. ABTS and FRAP showed wide variation from 4.37 to 29.30 ㎍ Trolox ㎎-1 dw and 3.18 to 10.8 ㎍ ASC ㎎-1 dw, respectively. RP and TPC were ranged from 3.43 to 9.51 ㎍ GAE ㎎-1 dw, and 0.8 to 18.63 ㎍ ASC ㎎-1 dw, respectively. Cluster analysis of A. ampeloprasum germplasm was divided into two major groups. Group Ⅰ (7 accessions) characterized as higher antioxidant activities than the group Ⅱ (15 accessions) and had similar antioxidant activities with A. tuberosum as a control. FRAP value showed a significant strong positive correlation with DPPH (r = 0.868*) and ABTS activity (r = 0.826*). Principal component analysis showed that the first two principal components (PC1 and PC2) cumulatively explained 85.64 % of total variation. Conclusion : From the above results, we may suggest that A. ampeloprasum aerial parts might have useful as a new material for functional food.

Abstract. In this study, we investigated whether the systemically administered capsazepine can prevent the capsaicin-induced desensitization ex vivo I guinea-pig bronchi. Pretreatment with capsaicin (2.5, 5 and 10 mg/kg, s.c.) induced the functional desensitization and the loss of substance P-like immunoreactivity (SP-LI) with a similar potency (ED_50: 3.31±0.57 and 4.81±0.89 mg/kg, respectively) in isolated guinea-pig bronchi. Capsazepine (30 mg/kg, s.c.) co-administered with capsaicin (5 mg/kg, s.c.) prevented the capsaicin (5 mg/kg, s.c.)-induced functional desensitization and loss of SP-LI. These results suggest that capsazepine can antagonize systemically the desensitizing action of capsaicin at the level of receptor, preventing the loss of SP-LI and the establishment of functional desensitization in guinea-pig bronchi. ⓒ 1999 Elsevier Science Inc.
