  • The fruiting body of Ganoderma lucidum (Polyporaceae) is one of the valuable crude drugs, which has been used clinically in Korea, China, and Japan for a long time as a tonic and sedative, and for the treatment of hepatopathy, chronic hepatitis, nephritis, gastric ulcer, hypertension, arthritis, neurasthenia, insomnia, asthma, and poisoning and chronic bronchitis. Nowadays, this mushroom is used for leukopenia and paid much attention as a home remedy. (omitted)

  • A chemical tool was developed for the analysis of complex mixtures such as crude drugs by the method of pattern recognition. Pattern recognition was accomplished by a multiple reference peak identification method and three kinds of outlier statistics. This tool was tested on the analysis of synthetic mixtures.

  • By treating crude enzyme extract from Aspergillus kawachii, the liquiritigenin content in the licorice (Glycyrrhizae Radix) was significantly increased. The liquiritigenin content reached its maximum level (45.7 mg/g licorice extract) after 60 min of incubation with the crude enzyme extract at $37^{\circ}C$, while the inactivated crude enzyme treated control contained trace amount (about 0.11 mg/g) of liquiritigenin. The enzyme-treated licorice extract inhibited more than 50% DPPH radical at 100 ppm and this was about two times higher activity compared to the enzyme-untreated control.

  • This experiment was performed to investigate whether the combined-preparation of crude drugs (The $Well^{TM}$ Preparation, TW), has hypnotic effects and/or enhances pentobarbital-induced sleep behaviors. TW was mixed with water extracts of Ginseng Radix red, Germinated brown rice, cultured mountain ginseng, and 50% ethanol extracts of Longanae Arillus, Nelumbinis Folium and Chrysanthemi Flos. TW (100 mg/kg, p.o.) reduced sleep onset and prolonged sleep time induced by pentobarbital similar to muscimol (0.2 ${\mu}M$), a $GABA_A$ receptor agonist. Also, TW (2 ${\mu}g$/ml) and pentobarbital (2.5 ${\mu}M$) did not affect the chloride influx in primary cultured cerebellar granule cells, respectively, but the combined-treatment of TW (2 ${\mu}g$/ml) and pentobarbital (2.5 ${\mu}M$) increased the chloride influx onto the cells. In conclusion, TW augments pentobarbital-induced sleep behaviors; these effects may result from chloride channel activation.

  • This study was attempted to investigate the effect of Composite Preparation (Sam Whang Sasim-Tang: SWST, Whang Ryun Haedok-Tang: WRHT) on the activities of GOT and GPT, the content of total lipids, triglyceride, total cholesterol. Phospholipid and ${\beta}-lipoprotein$ in the serum, and the change ratio of body and liver weight in the experimentally induced hyperlipemic rats, making use of the extract 150, 200, 300 and 500 mg/kg p.o. Significant test was performed by comparision with the values of corresponding experimentally hyperlipemic rats. The activities of S-GPT was significantly decreased in all dose of SWST and WRHT respectively. The activities of S-GPT was significantly decreased in dose of SWST 500 mg/kg and in all dose of WRHT respectively. The content of total lipids, triglyceride, total cholesterol and phospholipids were significantly decreased in all dose of two the extract. The rate of decrease on total lipids and triglyceride were remarkable in dose of SWST 300, 500 mg/kg and WRHT 200, 500 mg/kg, and then the content of total cholesterol was more remarkable in dose SWST 300, 500 mg/kg, and WRHT 150, 300 mg/kg, and the content of phospholipids was more remarkable in dose of the extract 150, 200 and 300 mg/kg. The content of ${\beta}-lipoprotein$ was significantly decreased in dose of WRHT 150, 200 and in all dose of SWST. Increase ratio of the body and liver weight were significantly decreased in dose of two the extract 300, 500 mg/kg respectively.

  • With the Sunshine policy, exchange of materials and cultures inter Koreas has been broadened and expectancy of reunification is getting higher. Especially, medical supplies and medicines are one of the biggest parts in the exchange goods. So, preparing an unified official drug standard preparing new medical administration system is required. We compared the Korean pharmacopoeia with North Korean Pharmacopoeia. Two pharmacopoeias have been developed in different direction and have many differences in the nomenclature and format. In this study, we compared general notices, general rules for preparations and crude drugs, monographs, general tests, processes and apparatus.

  • Activated macrophages express inducible isoforms of nitric oxide synthase (iNOS) and cyclooxygenase (COX-2), and produce excessive amounts of nitric oxide (NO) and prostaglandin E$_2$ (PGE$_2$), which play key roles in the processes of inflammation and carcinogenesis. The root of Paeonia lactiflora Pall., and the root cortex of Paeonia suffruticosa Andr., are important Chinese crude drugs used in many traditional prescriptions. 1,2,3,4,6-penta-O-galloyl-$\beta$-D-glucose (PGG) is a major bioactive constituent of both crude drugs. PGG has been shown to possess potent anti-oxidant, anti-mutagenic, anti-proliferative and anti-invasive effects. In this study, we examined the inhibitory effects of 1,2,3,4,6-penta-O-galloyl-$\beta$-D-glucose (PGG) isolated from the root of Paeonia lactiflora Pall. on the COX-2 and iNOS activity in LPS-activated Raw 264.7 cells, COX-1 in HEL cells. To investigate the structure-activity relationships of gallate and gallic acid for the inhibition of iNOS and COX-2 activity, we also examined (-)-epigallocatechin gallate (EGCG), gallic acid, and gallacetophenone. The results of the present study indicated that PGG, EGCG, and gallacetophenone treatment except gallic acid significantly inhibited LPS-induced NO production in LPS-activated macrophages. All of the four compounds significantly inhibited COX-2 activity in LPS-activated macrophages. Among the four compounds examined, PGG revealed the most potent in both iNOS ($IC_{50}$ = 18 $\mu\textrm{g}/mL$) and COX-2 inhibitory activity (PGE$_2$: $IC_{50}$ = 8 $\mu\textrm{g}/mL$ and PGD$_2$: $IC_{50}$ = 12 $\mu\textrm{g}/mL$), respectively. Although further studies are needed to elucidate the molecular mechanisms and structure-activity relationship by which PGG exerts its inhibitory actions, our results suggest that PGG might be a candidate for developing anti-inflammatory and cancer chemopreventive agents.

  • The water extracts of ten crude drugs were tested for the spasmolytic and anti-peptic ulcer activities on rat ileum smooth muscle contraction and aspirin-induced acute hemorrhag ic erosive gastritis respectively. The water extract of Aurantii immaturi pericarpium(AIP)($IC_{50}=1.5{\times}1O^{-2}$g/l), Aurantii nobilis pericarpium(ANP)($IC_{50}=2.5{\times}1O^{-2}$g/l), Cyperi rhizoma(CR)($IC_{50}=3.3{\times}1O^{-2}$g/l). Linderae radix(LR) ($IC_{50}=6.8{\times}1O^{-2}$), Aurantii fructus immaturus(AFI)($IC_{50}=11.8{\times}1O^{-2}$), Saussureae radix(SR)($IC_{50}=13.2{\times}1O^{-2}$g/l) and Ponciri fructus(PF)($IC_{50}=23.3{\times}1O^{-2}$g/l) showed inhibitory activity on the isometric contraction of rat ileum smooth muscle induced by electrical stimulation in a concentration-dependent manner, whereas the water extracts of Arecae pericarpium(AP), Agastachis herba(AH) and Magnoliae cortex(MC) potentiated the isometric contraction. In the aspirin-induced acute gastritis, the water extracts of MC, AP and CR reduced significantly the gastric juice secretion, gastric juice acidity and pepsin activity. They also showed protective activity of gastric mucosal layer from erosion and petichial hemorrhage in gross and histological examination.

  • Several kinds of medicinal plants are used as diuretics in folk medicines and oriental drugs. The diuretic action of water extracts of the ten kinds of crude drugs, such as Pachyma hoelen $R_{UMPHIUS}$ Zea mays L., Akebia quinata $D_{ECAISNE}$, Alisma orientale Juzepezuk, Atractylodes koreana $N_{AKAI}$, phytolacca americana L., Achyranthes japo-nica $N_{AKAI}$, Juncus decipiens $N_{AKAI}$, Prunella asiatica $N_{AKAI}$ and Artemisia capillaris $T_{HUNBERG}$ was examined in mouse and compared with aminophylline as a control the following results were obtained. The urine volume was found to be remarkably increased by the Pachyma hoelen RUMPHIUS, Phytolacca americana L., Prunella asiatica $N_{AKAI}$ and Artemisia capillaris $T_{HUNBERG}$, moderately increased by the Akebia quinata $D_{ECAISNE}$, Achyranthes japonica $N_{AKAI}$ and Juncus decipiens $N_{AKAI}$, and slightly increased by Zea mays $L_{ENNE}$, Alisma orientale $J_{UZFPEZUK}$ and Atractylodes koreana $N_{AKAI}$.
