Depression is very common mental disorder, so many people suffer from it, which makes the treatment of depression important. Many drugs to treat depression were developed and being prescripted. But they have a lot of side effects, so it needs to develop drugs without side effects or with less side effects. Herbal medicines have been used to treat not only physical disorder but also mental disorder and it has been reported that they have less side effects. Therefore, there is the need to discover and use herbal medicine with antidepressant effect. The purpose of this study was to reseach Antidepressant effect of Licium chinense Mill. and its influence on serotonin and its metabolite of depression model rats. We used 'forced swimming test(FST)' to know antidepressant effect of Licium chinense Mill. and HPLC to check the influence on serotonin and its metabolite(5-HIAA) of Licium chinense Mill. after rats' brains were divided into cerebral cortex, striatum, hypothalamus and hippocampus. The results were obtained as follows : In the study of antidepressant effect by 'forced swimming test(FST)' method, Licium chinense Mill. had a significant antidepressant effect. In the study of influence on serotonin and 5-HIAA by HPLC, Licium chinense Mill. mainly increased serotonin and 5-HlAA of cerebral cortex and striatum signigficantly among 4 parts of rat's brain above-mentioned. These results suggest that Licium chinense Mill. has antidepressant effect that may be related with the increase of serotonin and its metabolite as its mechanism, but more precise experiments will be need to prove their relation.

대황감초음자(大黃甘草飮子)와 그 구성약물군(構成藥物群)이 Alloxan 유도 당뇨(糖尿) 백서(白鼠)의 혈청 조성 및 항산화 효과에 미치는 영향

The purpose of this study was to reseach the effect of Daehwanggamchoeumja(大黃甘草飮子) and its component groups on diabetes, free radicals, and antioxidants system in Alloxan-induced diabetic rats. The experimental group was divided into three groups: Daehwanggamchoeumja(DG), and its components groups, Gamdutang (Gamcho&Daedu; DG-I) and Daehwanggamchotang(DG-2). The results were obtained as follows: 1. In the study of effect on diabetic metabolic dysfunction(Glucose, Triglyceride, Total Cholesterol, HDL Cholesterol, Total Protein, Albumin, Creatine, BUN), only DG has a significant effect. 2. In the study on free radical scavenging effect in vitro(the suppressing effect on peroxidation of linoleic acid on concentration, the scavenging effect of DPPH radical, inhibitory effect of superoxide in xanthine-xanthine oxidase system, inhibitory effect on lipid peroxidation reaction by hydroxy radical in $H_2O_2Fe^{2-}$system, and the effect on Nitrate reductase activity), DG and DG-2 have more effect than DG-l relatively. 3. In the study on antioxidants system in vivo(The level of serum LPO, The level of hepatic LPO, Catalase, GSH, GST), only DG has a significant effect. These results suggest that Daehwanggamchoeumja(大黃甘草飮子) has an effect on diabetes, peroxidative damage by free radical, so it seems to be useful to prevent and treat diabetes. The mechanisms of these are supposed to be involved in antioxidant and three drugs' cooperative synergy effect.
