In search for the plant-derived antioxidant compound, it was found that the EtOAc, BuOH extracts obtained from the leaves parts of Oryza sativa L. which exhibited a significant antioxidant activity from 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical cleavage. Activity-guided fractionation on the basis of the inhibitory activity upon the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical cleavage. and repeated column chromatography afforded several antioxidant compounds from Oryza sativa L. The structures and stereochemistry of these compounds were established on the basis of analysis of spectra and some chemical transformations as follows: 5,7-dihydroxy- 8-methoxyflavone, $acacetin-7-O-{\beta}-rutinoside$, $pectolinarigenin-7-O-{\beta}-rutinoside$. At antioxidant activity test for isolated three compounds, antioxidant activity was showed too.

Purpose: The purpose of this study was to investigate actor and partner effects of sexual attitude and marital intimacy on sexual satisfaction in pregnant couples. Methods: Data were collected from 176 pairs of the pregnant couples visiting for prenatal care at hospitals from June 18 to September 24, 2016. The collected data were analyzed by paired t-test and Pearson's correlation coefficients using SPSS 18.0 and interdependent effect (Actor-Partner Interdependence Model analysis) through AMOS 18.0. Results: The sexual attitude and marital intimacy of the pregnant woman did not have a partner effect on the sexual satisfaction of her husband, respectively (${\beta}=.12$, p=.141), (${\beta}=.01$, p=.938). The sexual attitude of the husband had a partner effect on the sexual satisfaction of the pregnant woman (${\beta}=.13$, p=.021), but the marital intimacy of the husband did not show a partner effect (${\beta}=.07$, p=.202). Conclusion: Study suggests that the sexual attitude and marital intimacy of pregnant couples should be considered as factors when developing an intervention to improve sexual satisfaction in couples. Moreover, pregnant couples should participate in intervention together because the sexual satisfaction has conceptual view of interdependence in two-person relationships.

Objectives : The aim of this study was to investigate the effect of Jaeumyangyung-tang(滋陰養榮場(JY), JA-0.65g/kg;JB-1.3g/kg) on hyperglycemic mice induced with streptozotocin(STZ). Methods : The experiment operated for 6 weeks. The rats were divided into 3 groups : diabetic group(control group), diabetic group treated with JA(0.65g/kg) for 6 weeks, and diabetic group treated with Jb(1.3g/kg) for 6 weeks. Results : In the STZ-induced diabetic group, blood glucose levels significantly increased as well as the loss of body weight. The levels of serum glucose decreased significantly (p<0.05 or p<0.01) in the JA and JB groups compared with the control. According to a tolerance test, intraperitoneal glucose was ameliorated in the JA and JB groups. The blood urea nitrogen (BUN) and creatinine levels slightly decreased. Histologic analyses of the pancreases revealed that the ${\beta}-cells$ on Langerhans' islets were destroyed by STZ, but the ${\beta}-cell$ mass was larger in the JY than in the control mice. Conclusions : These results indicate that JY can exert beneficial effects on diabetes. preservation of in vivo ${\beta}-cell$ function and regeneration of ${\beta}-cell$ dysfunction by STZ.
