In the result of investigating traditional chinese medical literatures to understand definite immunopharmacologic effects of drugs for clearing away heat and detoxicating such as Sophorae tonkinensis Radix, Houttuyniae Herba, Smilacis glabrae Rhizoma, Belamcandae Rhizoma, Lasiosphaera seu Calvatia, Paridis Rhizoma, Lobeliae chinensis Herba, we could reach conclusions as follows: 1. Sophorae tonkinensis Radix, Houttuyniae Herba can increase voracity of leukocytes and activities of T cells. 2. Sophorae tonkinensis Radix, Smilacis glabrae Rhizoma can inhibit DTH. 3. Sophorae tonkinensis Radix, Houttuyniae Herba increase activities of B cells in low density but decrease activities of B cells in high density. 4. Sophorae tonkinensis Radix, Houttuyniae Herba, Smilacis glabrae Rhizoma, Belamcandae Rhizoma have anti-inflammatory effects. Studies about drugs for clearing away heat and detoxicating is on. but their range is wide and their effects are numerous. Therefore. we think that more deep and wide researches about them shoud be accomplished.

Protein tyrosine phosphatase 1B (PTP1B) is predicted to be therapeutic target in treatment of type 2 diabetes and obesity. Thus, in order to search for PTP1B inhibitors, we screened the inhibitory activity of PTP1B in the water extracts of 84 medicinal herbs. Among them, the extracts of Pini Folium, Magnoliae Cortex, Artemisiae asiaticae Herba, Schizonepetae Herba, Menthae Herba, Mume Fructus, Cimicifugae Rhizoma, and Amomi Cardamomi Fructus showed relatively significant (58-68%) inhibitory activity against PTP1B. Especially, the methylene chloride fraction of the methanol extract of Menthae Herba (81% inhibition at 30 ${\mu}g$/ml) showed more potent inhibitory activity against PTP1B than others.

Yersinia enterocolitica, which causes yersiniosis, is a bacterium that produces biofilms effectively. The inhibition of biofilm formation provides a method for preventing infections with Y. enterocolitica. In this study, the inhibitory activity of Y. enterocolitica biofilm formation was investigated in a library of 140 edible plant methanol extracts including forest products. It was identified that the biofilm formation could be inhibited by 12 extracts of plants, Agastachis Herba, Agrimoniae Herba, Diospyros kaki leaves, Elsholtziae Herba, Ginkgonis Semen, Lycopi Herba, Melonis Pedicellus, Menthae Herba, Mori Radicis Cortex, Polygoni Multiflori Radix, Prunellae Spica, and Schizonepetae Spica. After changing the solvent to ethanol and water, the greatest inhibition of biofilm formation was produced by a 50% ethanol extract of Polygoni Multiflori Radix. A method to effectively prevent yersiniosis can be developed using the edible plant extracts identified in this study.

This study is an attempt to investigate the effects of the water extracts of the whole plants of Prunella vulgaris (Labiatae) and Thesii chinense (Santalaceae) on the acute toxicity, the activities on central nervous system and the diuretic action. The acute toxicities shown by $LD_{50}$ were estimated to be more than 3000 mg/kg p.o. and 1,000 mg/kg s.c. in the extracts of Prunellae Herba and Thesii Herba, respectively, in mice. The extracts at a dose of 2,000 mg/kg p.o. did not show any activities on central nervous system, i.e, sedative, analgesic, hypothermic and anticonvulsant actions. The urination in rats was increased by 45.5% and 57.6% when 100mg/kg of each of the extracts were given orally. The results obtained revealed that the water extracts possessed weak diuretic actions without any of central nervous system activities. Furthermore, it is considered that the potassium in the extract may play a role in the diuretic action.

Objectives : Herba on lipid levels in serum and lipid accumulation in liver tissue in high fat diet-induced hyperlipidemic mice. Methods : Experimental groups were subdivided into four; Normal diet group (Nor), Hyperlipidemic mice (Con), Lysimachiae Herba water extract administered mice (LWE), Lysimachiae Herba methanol extract administered mice (LME). Thereafter the changes in body weight, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, AST, ALT, fasting blood glucose in serum were measured. In addition histopathological changes in liver tissue was also observed. Results : Body weight, AST and ALT were not affected by the administration of water or methanol extracts of Lysimachiae Herba. However, methanol extracts of Lysimachiae Herba down regulated the total cholesterol and triglyceride in high fat diet - induced hyperlipidemic mice. Conclusions : In this study, results of total cholesterol and triglyceride showed significant effect in LME compared with LWE, but other results didn’t. Therefore, it is necessary to have more study of Lysimachiae Herba to apply hyperlipidemia.

Background: Cancer reseach is done in earnest world-wide, because cancer is one of most threatening diseases to humans. Orostachyos Herba is a widely used herb that has long been in use in Korea as an anti-inflammatory and anti-cancer therapy. The purpose of this study is to verify any anti-cancer effects on stomach and liver cancer in vitro. Materials & Methods: AGS and KATO III stomach cancer cells and Hep3B and HepG2 liver cancer cells, all obtained from Korean Cell Line Bank, were used. The boiled extract of Orostachyos Herba(20 and 40 microliters) were injected into cultures and observed at 0 hours, and at 24-hour intervals up to 96 hours. The destruction of stomach and liver cancer cells was measured through Trypan blue exclusion testing. The suppression on viability of stomach and liver cancer cells was observed, and anti-cancer mechanisms was examined by analyzing the cell cycle. Results: In morphologic change, AGS, KATO III, HepG2 and Hep3B showed some of the withdrawn and floating appearance that is typical in cellular imparment. AGS, KATO III, HepG2 and Hep3B showed more destruction of stomach cancer cells in each test group than in the control group to a statistically significant degree. Analysis of the cell cycle after introduction of Orostachyos Herba showed very little inhibition of divisions of all cell lines. Conclusions: This experiment suggests that Orostachyos Herba has some anti-tumor effects on stomach and liver cancer cells. Progressive research on Orostachyos Herba and it's anti-tumor effects will be needed to determine its practicability as a cancer treatment.

Purpose: Ligustri Lucidi Fructus and Ecliptae Herba has long been used for clinical therapy associated especially with menopausal symptoms in Korea. To provide a scientific rationale for such use, we have investigated the antioxidant and vasorelaxant effects of Ligustri Lucidi Fructus, Ecliptae Herba and its mixture. Methods: The antioxidant activity of the extracts from Ligustri Lucidi Fructus, Ecliptae Herba and its mixture were evaluated and compared with that of BHA (butylated hydroxyanisole), BHT (butylated hydroxytoluene), vitamin C and vitamin E, using the ${\alpha}$,${\alpha}-diphenyl-{\beta}-picrylhydrazyl$ (DPPH) radical scavenging method. Results: Antioxidant activity of all extracts using the DPPH radical scavenging method decreased in the order vitamin C>BHA>vitamin E>Ligustri Lucidi Fructus>Ligustri Lucidi Fructus:Ecliptae Herba(1:1)>Ecliptae Herba>BHT. The vasorelaxant effects of extracts were investigated on the vasomotor tone of the rat thoracic aorta in an organ bath. All of the extracts elicited along-term relaxing response in the endothelium-intact as well as endothelium-denuded rat aorta contracted with norepinephrine. This relaxant effect was abolished by Precontraction with 72 mM KCI. Thus, it is suggested that the mechanism of vasorelaxant effect of extracts not involve voltage-operated $Ca^{2+}$ channel blocking but receptor-mediated route. Conclusion: These antioxidant and vasorelaxant effecs of the extracts may contribute to the beneficial effects in postmenopausal women.

Objectives: Asari Herba comes from the dried perennial herbaceous plant, Asarum sieboldii $M_{IQ}$., A. heterotropides $F_R$. SCHMIDT var. mandshuricum($M_{AXIM}$) $K_{ITAG}$. and A sieboldii $M_{IQ}$ var. seoulense $N_{AKAI}$., family Aristolochiaceae. This medicine is pungent in flavor(味辛), warm in nature(性溫), mildly toxic and affects the lung, kidney, and heart meridians. It is able to repel wind dispel cold(祛風散寒), remove the obstruction of the nose(宣通鼻竅), relieve pain(止痛) and warm the lungs to remove the retention of fluids(溫肺化飮). In a clinic it is prescribed for exterior syndrome of wine-cold type(風寒表證) manifested as headache and general pain. It is indicated for headaches, toothaches, bisyndrome of wind-cold-dampness type(風寒濕痺), etc. For many generations medical books have warned doctors that the dosage of Asari Herba should not be excessive because the pungent flavor has the effect of dispersing exopathogens from superficies of the body. The principle, 'Asari Herba should not exceed Jeon(錢, Qian, 3.0 gram)' is still considered to be relevant. Methods : Extensive research of several ancient medical texts has lead to the following conclusion. Results : The statement 'Asari Herba should not exceed Jeon' is a dosage which is used to prepare single recipe and powder. Conclusion : The definition of Jeon is not 1 Jeon(3.0 gram), but 1 Jeonbi(錢匕, Qianbi, 1.0 gram), moreover, the usage, collection. and refinement process are not in accordance with the contents of the ancient medical texts. A deeper study of Asari Herba's dosage in the future is expected to have interesting results.
