The protective effects of the water extracts of nine kinds of medicinal herbs, which have been reputed to having the hepatoprotective activity in Chinese herbal medicine, on BNL cl.2 cells using a MTT assay were investigated. Five extracts including Coriolus versica, Curcuma longa, Phellinus linteus, Po-lygonum aviculare, and Salvia miltiorrhiza showed the protective effects on BNL cl.2 cells damaged by $CCl_4$ with $ED_{50}$ values of less than $100\;{\mu}g/ml$. Silymarin had been used as a positive control.

'JaGuiNaMu' is one of the Korean crude drugs used mainly to cure neuralgia, bone fracture, jaundice, and headache. With regard to the botanical origin of 'JaGuiNaMu', it has been considered to be Albizzia species of Leguminosae, but there was no pharmacognostical confirmation on it. To clarify the botanical origin of 'JaGuiNaMu', the anatomical characteristics of the branch of Albizzia species growing wild in Korea, A. julibrissin and A. coreana were studied. As a result, it was clarified that 'JaGuiNaMu' was the branch of Albizzia julibrissin.

HooBakIp is one of the Korean crude drugs used mainly to cure a headache, apoplexy and dyspepsia. With regard to the botanical origin of HooBakIp, it has been considered to the Machilus thunbergii of Lauraceae in Korea. But there has no pharmacognostical conformation on it. To clarify the botanical origin of HooBakIp, the anatomical characteristics of the leaf of Machilus thunbergii, Machilus thunbergii var. obovata and Machilus japonica were studied. As a result, it was clarified that HooBakIp from Korea was the leaf of Machilus thunbergii.

It is the purpose of this article to present a brief and systematical behavioral methods in recent developed behavioral pharmacology. Specifically, the present review has been organized around three major topics reflecting both current research emphasis in behavioral pharmacology and methodological applications to the study of psychopharmacological actions of crude drug or herb medicine. The first major topic focuses upon the appropriate experimental design especially in the study of psychopharmacology. A large number of factors should be controlled to have a bearing on design of studies reflecting to psychological effects of drugs. The second section presents several recent methodological developments in behavioral pharmacology involving Turner's screening methods and several types of conditioning techniques. The last section calls specific attention to the observation of behavioral development processes in relation to the activity of pharmacological agents and emphasizes critical period of drug treatment.

'Bojungikgi-tang' consists of Astragali Radix, Ginseng Radix, Atractylodis Rhizoma alba, Glycyrrhizae Radix, Angelicae gigantis Radix, Aurantii nobilis Pericarpium, Cimicifugae Rhizoma and Bupleuri Radix. It has been widely prescribed in oriental medicine for controlling digestive functions and for health. Experimental studies were implemented on analgesic, sedative and antipyretic actions. The results showed significant analgesic and antipyretic actions were recognized. Sedative actions were significantly noted.

The antioxidant activities of the root of Panax ginseng and the root bark of Acanthopanax senticosus were compared by in vitro and in vivo experiments. The results of in vitro experiments showed no significant difference between the antioxidant activities of both crude drugs. However, the results of in vivo experiments showed much higher antioxidant activities in Panax ginseng than Acanthopanax senticosus, showing about 80 times greater activity.

There are many reports on the stability of drugs in powders and various dosage forms. The author studied on the stability of ascorbic acid mixed with talcs. From the result of this experiment, it was considered that talcs markedly accelerated oxidative degredation of ascorbic acid in powders and the acceleration rate depends on the varieties of crude talcs. Iron salts seem to be the principal factor influencing the degradation of ascorbic acid Degradation rate of ascorbic acid mixed with purified talc is significantly slower than that with the crnde talcs. The more the concetration of ascorbic acid is diluted, the faster the degradation rate and degredation rate of Ascorbic acid is the function of tme.

The Korean peninsula, located between the vast Chinese mainland and Japan, has a unique cultural background that goes back five thousand years. In ancient times, the region was deeply influenced by Chinese culture, and traditional medicine in Korea was no exception. The Korean character, HAN GUL (24 alphabets), was invented at in the early 1400s by The Great King Sejong (1397-1450) of the Chosun dynasty. But few changes were made to traditional medicines for about 500 years thereafter. At the start of the 20th century, missionaries from western countries introduced new concepts and techniques of medicine. During the last century, there was enormous development in modern medical sciences. Even today, however, natural medicine -including folk medicine (or traditional Chinese medicine) - plays an important role in Korean health care. In this paper, we will review and discuss traditional Korean medicines as it has evolved over the past three thousand years.

To investigate the experimental effects of Chunwangboshimdan which have been widely used for aterial or auricular flutter, neurosis, insomnia and disease caused by cardiac malfunction, we have done the effects on the central nervous and cardiovascular system. The result as follow; It inhibited the convulsion induced by caffeine, the writhing syndrome induced by acetic acid and the spontaneous movement. Furthermore it prolonged the sleeping time induced by thiopental-Na in mice. It also showed the negative inotropic action on the isolated heart of frog, the vasodilative action as to peripheral bloods of rabbit ear and the hypotensive action in the anesthetized rabbit.

This study was attempted to examine the acute toxicity and the effect of Sopunghwalhul-Tang water extract(SHTE) on analgesic action in mice, anti- inflammatory action in rats and blood pressure in rabbits. The results were as follows; SHTE showed 10% mortality at 2,000mg/kg(p.o.), had significant analgesic activity in the pain caused by 0.7% acetic acid and was shown to have significant anti-inflammatory activity in the edema-induced by 5% acetic acid at 450mg/kg. SHTE given into a ear vein of rabbits produced a dose-related vasodepressur responses. SHTE-induced hypotension was significantly inhibited by pretreatment with atropine, but was not affected by chlorisondamine, phentolamine, propranolol, and dephenhydramine.
