Korean ginseng (Panax ginseng C. A. Meyer) has been used as an important medicinal plant in the Orient for a long time. It has been claimed that ginseng has many beneficial bioactive effects on human health, such as antitumor, antistress, antiaging and enhancing immune functions. Red ginseng possibly have new ingredients converted during steaming and dry process from fresh ginseng. In this study, pharmacological efficacy and ingredient conversion of ginseng by 9 repetitive steaming and drying process were investigated measuring conversion efficiency of acidic-polysaccharide, phenolic compounds and inhibition of peroxide lipides. It was found that acidic-polysaccarides were increased by heat treatment. In addition, maltol of phenolic compounds, strong antioxidant, produced during the process of red ginseng by Maillard reaction. Acidic-polysaccarides and maltol were increased after the 1st and 3rd steaming and drying treatments, but they were decreased gradually after 5th, 7th, and 9th treatments. Antioxidant activity was increased as increasing treatment times of steaming and drying without significance. Effect of red ginseng extract on inhibition of peroxide was increased gradually until after the 7th treatment, but remarkably decreased after the 9th treatment.

Berberine, a protoberberine isoquinoline alkaloid, showed inhibitory effects on dopamine content in PC12 cells $(53.8\%\;inhibition\;at\;20\;{\mu}M)$. Tyrosine hydroxylase, the rate-limiting enzyme in the catecholamine biosynthetic pathway, was inhibited at $20\;{\mu}M)$ of berberine by $21.8\%$ relative to control. Thus, we hypothesized that the inhibition of tyrosine hydroxylase by berberine might be partially contributed to the decrease in dopamine content in PC12 cells. Furthermore, we investigated the effects of berberine on catecholamine content of serum after immobilization and cold stress in mice. Adult male mice were either subjected to 30 min of restraint or to 2 hr of cold chamber at $4-6^{\circ}C$. Serum norepinephrine, 16.8 pmol/ml, in control mice was increased to 28.8 pmol/ml by immobilization and the stress-induced rise in serum norepinephrine was partially blocked by the treatment of berberine (10 mg/kg, i.p.) once a day for 6 days. Berberine (10 mg/kg/day for 3 days, i.p.) also inhibited the increase in serum norepinephrine by cold stress in mice. These results suggest that berberine may be developed as the promising antistress agent.

This experiment was conducted to study anti-stress effects of Guibiondamtang on several measures of stress, which were number of lever pressing, weight changes, water intake and gastroduodenal ulcer. The following results were observed: 1. There were no significant differences between the control group and the sample group in total number of lever pressing. And no significant differences were observed in the shock duration and the shock length. 2. The median water intake during the stress was 25ml for the sample group and 17ml for the control group and the difference was not statistically significant. 3. The median body weight losess after the psychological stress was given were 28g for the sample group and 35g for the control group and the difference was not statistically significant. 4. The mean frequencies of gastric ulcers induced by the psychological stress were 0.3 for the sample group and 2.3 for the control group and the difference was statistically significant. 5. The mean lengths of gastric ulcers induced by the psychological stress were 0.3mm for the sample group and 2.8mm for the control group and the difference was statistically significant. 6. The mean ratings of gastric ulcers induced by the psychological stress were 0.7 for the sample group and 1.9 for the control group and the difference was stastically significant. Thus it may be concluded that Guibiondamtang has an antistress effect.

The main aim of this study was to investigate stress related activities of ginsenosides and their action mechanism. Control group and ginsenoside supplemented groups were exposed to stress while no-stress group was not done. Animals of each group (n=$8\~10$) were orally administerd 100 mg red ginseng extract (R-G), or 10 mg ginsenosides/kg body weight once a day. Animals were given materials for 5 days without stress, and then were given supplements for 5 days with restraint and electroshock stress. Mice were given materials for 5 days for experiments on anti-fatigue effect. After loading final stress, stress-related behavioral changes of experimental animals were examined and plasma corticosterone levels were measured. R-G and ginsenoside $Rb_{1}$ supplementation partially blocked the stress effects on locomotion and elevated plus-maze test in rats and mice. They also partially blocked stress induced behavioral changes such as freezing, smelling, face-washing, rearing behavior in rats. R-G and $Rb_{1}$ decrease adrenal gland size and plasma corticosterone level, which were increased by stress in rats. R-G increased enduring time on the Rota rod, cold water and horizontal wire, but $Rb_{1}$ didn't. Effects of $Rb_{1}$ on plusmaze test were inhibited by administration of flumazenil. These results suggest that $Rb_{1}$ is the main antistress principle in ginseng and it's effect is modulated by GABAnergic nervous system.

The effects of Semen Ziziphi Spinosae extract were tested for the anti-stress action. 100g of crude drug of Semen Ziziphi Spinosae was extracted with pure water and the total extractive was evaporated under reduced pressure to give 10.7g. ICR male mice($20{\pm}2g$) were fed orally with the dose of 100mg/kg/day for five days. Foot shock was given to make experimental environment of physiological stress. Foot shock mice were placed individually in the foot shock compartments and sociopsychological mice were placed nonfoot shock compartment-the side of foot shock compartments. Mice were exposed to sociopsychological stress by restraining and seeing foot shock stressed mice for one hour for five days. Semen Ziziphi Spinosae extract administered group showed a significant decrease of serum corticosterone secretion compared with control group. Noradrenaline secretions in the dorsal cortex of brain were increased but not significant. Lipid peroxidation of the liver of mice were tested by measuring malondialdehyde, and Semen Ziziphi Spinosae extract had tendency of decreasing lipid peroxidation but not significant. But Semen Ziziphi Spinosae extract administration had the effect of decreasing serum level of aspartate aminotransferase and malondialdehyde. These results suggest that Semen Ziziphi Spinosae extract can effectively rid the sociopsychological stress and stress concerned diseases.

Korean ginseng (Panax ginseng C. A. Meyer) has been used as an important medicinal plant in the Orient for a long time. It has been claimed that ginseng has many beneficial bioactive effects on human health, such as antitumor, antistress, antiaging and enhancing immune functions. Red ginseng possibly have new ingredients converted during steaming and dry process from fresh ginseng. Kujeungkupo method which means 9 repetitive steaming and drying process was used for the processes of green tea, Polygonatum odoratum, and Rehmanniae radix preparata. In this study, ingredient conversion of ginseng by 9 repetitive steaming and drying process were investigated measuring conversion efficiency of brown materials, crude lipids, crude proteins and aromatic compounds. Brown materials, as an antioxidant, in red ginseng were produced through non-enzymatic reaction by heat. Repetitive steaming and drying treatments on ginseng root contiunously increased the content of brown materials and the chromaticity. Crude lipids were degraded by heat and converted into volatile aromatic ingredients. Crude lipids were degraded and decreased by 0.52% after the 5th and 7th. Crude proteins were also decomposed and converted to amino acid. Crude proteins after the 9th treatment were decreased by more than 85% as increased times of treatments. A bicyclogermacrene as aromatic material was decreased as increased treatment times, while but a aromatic caramel was increased.

In order to investigate pharmacological properties of New Woohwangchungsimwon Pill (NWCH) and Woohwangchungsimwon Pill(WCH), effects of NWCH and WCH on cerebral ischemia and central nervous system were compared. Cerebral ischemia insult was performed using unilateral carotid artery occlusion in Mongolian gerbils. The histological observations showed preventive effect of NWCH and WCH treatments with ischemia-induced brain damage. The ATP in brain tissue was decreased in vehicle-treated ischemic gerbils. This decrease was prevented by NWCH and WCH treatment. In contrast to what was seen with ATP, the lactate and lipid peroxide were both elevated in vehicle-treated ischemic gerbils. This elevation was inhibited by NWCH and WCH treatments. In central nervous system, NWCH and WCH had sedative effect in rotarod and spontaneous activity test, but no effects on the hexobarbital-induced sleeping time. And, NWCH and WCH had weak anticonvulsion effects in electric shock- and pentetrazol-induced convulsion test. NWCH and WCH increased the respiration rate, but decreased the respiration depth in rats. Furthermore, NWCH and WCH showed antistress effect. Our findings suggest that the pharmacological profiles of NWCH on cerebral ischemia and central nervous system are similar to that of WCH.

WooHwangChungSimWon is a traditional medicine for treatment of hypertension, arteriosclerosis, coma, and stroke in China, Korea, and Japan. In the new prescription of WooHwangChungSimWon, the civet is substituted for the musk, the major component of WooHwangChungSimwon, because of the prohibition law about the musk. We have made a comparative study of the effects on the central nervous system between the musk containing and civet containing WooHwangChungSimWon. In order to investigate the effects on the central nervous system, we have examined spontaneous motor activities, anti-convulsion activities induced by chemicals or electric shock, sleep induced by hexobarbital, and antistress effects. In the examination of anti-convulsion effects against the electric shock and injection of pentetrazol, only the civet containing WooHwangChungSimWon showed the anti-convulsion effects, i.e. the duration of convulsion by electric shock was decreased (control: 104.0 seconds, low dose of civet containing WooHwangChungSimWon: 60.7 seconds) and the duration of suppression against pentetrazol induced convulsion was increased (control: 392.3 seconds, low dose of civet containing WooHwangChungSimWon: 574.0 seconds, high dose of civet containing WooHwangChungSimWon: 561.4 seconds). In the other examinations, all kinds of WooHwangChungSimWon showed sedation, anti-convulsion activities, and induction of sleeping. These results suggest that there are no significant differences between the musk containing and civet containing WooHwangChungSimWon except the anti-convulsion effects against the convulsions induced by electric shock and pentetrazol.
