The effect of gradient eluted fractions from Et$_2$O extracts of Polyporus umbellatus screlotium was investigated on the viability of leukemia cell lines, K-562, L-1210, HL-60 and U-937 cells. Among those fractions, fraction 2 showed mild cytotoxic effect on L-1210 and HL-60 cells. Fraction 3 showed cytotoxic effect on 4 cell lines, and cytotoxic effect was the most potent on L-1210. The hallmark of apoptosis, DNA fragmentation, also appeared by fraction 3 on L-1210 after 48 hr treatment. Furthermore, this fraction was shown to be able to induce cell death on L-1210 cells by the inhibition of DNA synthesis in [$^3$H]thymidine incorporation test. From these results, P. umbellatus involves a potent chemical component that inhibits the viability of leukemia cell lines, L-1210. Further studies about the components of fraction 3 to function as a apoptosis inducer are necessary.

Objectives : The purpose of this study was to investigate melanogenesis inhibition of ethanol extract of Polyporus (EP) by using B16F10 melanoma cells. Methods : We measured antioxidant effect of EP by using 1,1-Diphenyl-1-picrylhydrazyl (DPPH) assay and we confirmed melanin contents and tyrosinase activity of EP in cells. Additionally, the expression of tyrosinase-related protein-1 (TRP-1) and TRP-2 was observed by Western blot. Results : EP showed significantly high radical scavenging activity and inhibition of melanogenesis in dose-dependent manner by decreasing cellular tyrosinase activity and melanin content with or without α-melanin stimulating hormone. TRP-1 and TRP-2 expressions were also suppressed by EP in B16F10 cells. Conclusions : These results suggest that EP inhibits the melanogenesis and it could be a new organic ingredient for hyper-pigmentation.

Objective: This study investigated the effect of purified medical herb extracts such as Alisma canaliculatum and Polyporus umbellatuson adipogenic differentiation of human bone marrow derived mesenchymal stromal stem cells (hBMSCs). Methods: Two different medical herb were extracted using hot distilled water. The optimal concentration of extracts were fixed at 100 ng/ml by means of cell viability and cytotoxic assay. To test the adipogenic differentiation ability of extracts, we induced the adipogenesis of hBMSCs for 21 days. At day 5, the cell was harvested to check mRNA and protein expression level of adipogenic related factors. The efficacy of lipid droplet formation was evaluated using the oil-red O staining method at days 21. Results: Two different medical herb extracts have no toxicity on hBMSCs. And two different medical herb extracts significantly decreased formation of lipid droplet compared with control groups in hBMSCs. The A. canaliculatum extract group showed the lowest mRNA and protein expression level of adipossgenic related transcription factors. This data suggests that extract of A. canaliculatum and P. umbellata decrease the adipogenic differentiation of hBMSCs. Conclusions: Our findings indicate that water-extract of A. canaliculatum and P. umbellata will be useful therapeutic reagents for prevention of obesity related disease such as diabetes, hyperlipidemia, coronary artery disease, and osteoporosis.

Objectives : This study was designed to investigate possibilities of herbal acupuncture for obesity. Methods : We researched into 23 kinds of literature and considered acupoints and herbs of herbal acupuncture for obesity. Results : Prescriptions for obesity include Erchentang(二陳湯), Liujunzitang(六君子湯) for phlegm-retention syndrome(痰飮), Wulingsan(五?散), Qianghuoshengshitang(羌活勝濕湯), Shenshitang(渗濕湯), Lingguishugantang(?桂朮甘湯) for Dampness syndrome(濕證) and Pingweisan(平胃散) for activating spleen and stomach(運化脾胃). And Rhizoma atractylodis(蒼朮), Tuber pinelliae(半夏), Rhizoma atractylodis macrocephalae(白朮), Fructus ponciri(枳殼), Fructus immaturus ponciri(枳實), Poria(茯?), Semen coicis(薏苡仁), Rhizoma alismatis(澤瀉) Fructus amomi(砂仁), Polyporus umbellatus(猪?), Medulla tetrapanacis(通草) can be used for both herbal medication and herbal acupuncture. And also there are some important acupoints for treating obesity, which are Sanyinjiao(三陰交), Pishu(脾兪), Gongsun(公孫), Fenglong(豊隆), Yinlingquan(陰陵泉), Zusanli(足三里), Qihai(氣海), Sanjiaoshu(三焦兪), Zhongwan(中脘), Neiguan(內關), Weishu(胃兪), Shenshu(腎兪) and Shangjuxu(上巨虛). Conclusions : We recommend that herbal acupuncture can be used for obesity. This method is a kind of injection using herbal extract, which can apply pharmacognosy theory and meridian system at the same time.

Objectives This paper investigates the origin, the progressive changes and the constructive principles of Jeoryoungchajeonja-tang(猪苓車前子湯).Methods Jeoryoungchajeonja-tang and other related prescriptions were analyzed in terms of their pathological indications, based on previous literature including 『Sanghannon(傷寒論)』, 『Keumkuaeyoryak(金匱要略)』, 『Donguibogam(東醫寶鑑)』, 『Donguisusebowon‧Sasangchobongwon(東醫壽世保元‧四象草本卷)』, 『Donguisusebowon‧Gabogubon(東醫壽世保元‧甲午舊本)』, 『Donguisusebowon‧Sinchukbon(東醫壽世保元‧辛丑本)』Results and Conclusions 1) The origin of Jeoryoungchajeonja-tang is discovered in the prescriptions for Lee-su(利水), that is, Jeoryoung-tang(猪苓湯). 2) Ohryoung-san(五苓散) introduced in 『Donguisusebowon‧Sasangchobongwon(東醫壽世保元‧四象草本卷)』progressively transformed into Shihosaryoung-san(柴胡四苓散)(『Donguisusebowon‧Gabogubon(東醫壽世保元 ‧甲午舊本)』) and ultimately into Jeoryoungchajeonja-tang(『Donguisusebowon‧Sinchukbon(東醫壽世保元‧辛丑本)』), a prescription appropriate for usage in the Mangeum symptomatology(亡陰證). 3) The Jeoryoungchajeonja-tang is composed of 10 herbs. Of these, Notopterygium incisum Ting(羌活), Aralia cordata Thunb.(獨活), Schizonepeta tenuifolia Briq.(荊芥), Saposhnikovia divaricata Schischk.(防風) make the Pyoeum(表陰) drop, and Anemarrhena asphodeloides Bge.(知母), Gypsum fibrosum(石膏) scatter the uihwa(胃火), and Poria cocos Wolf.(茯苓), Alisma canaliculatum(澤瀉), Polyporus umbellatus Fr.(猪苓), Plantago asiatica L.(車前子) facilitate urination.

Oryeong-san (ORS) is a traditional Korean herbal medicine widely used for renal associated diseases, composed of five medicine herbs; Atractylodes japonica Koidzumi, Cinnamomum cassia Presl, Polyporus umbellatus Fries, Poria cocos Wolf and Alisma orientale Juzepzuk. We studied to improve the convenience of intake and portability by developing modernized dosage forms, and examined the effect on anti-inflammation of ORS. In order to develop the tablet formulation of ORS (ORS-F), the tablets were evaluated on the basis of physical characteristics include diameter, thickness, weight variation, hardness, friability and disintegration. To analyze the marker components of ORS-F, eight index markers from five herbal medicines were chosen. And the method using high performance liquid chromatography (HPLC) with diode-array detector method was established for the simultaneous analysis. The biological activities were examined the effect of ORS-F on pro-inflammation mediated by LPS-stimulation. The production of nitric oxide (NO) and cytokines were determined by reacting cultured medium with griess reagent and enzyme-linked immunosorbent assay (ELISA). The expression of cyclooxygenase-2 (COX-2) and inducible NO synthase (iNOS) were investigated by Western blot and RT-PCR. The anti-oxidant activities of OJS-F increased markedly, in a dose-dependent manner. and, The total phenolic compound and flavonoids contents of OJS-F were 10.20±0.09 ㎍/㎎ and 12.86±0.86 ㎍/㎎. OJS-F which is LPS has diminished in the LPS-induced release of inflammatory mediators (NO, iNOS, COX2 and PGE2) and pro-inflammatory cytokines (TNF-α, IL-6 and IL-1β) from the RAW264.7 macrophages. Therefore, the developed formulation for tablet of ORS-F provide efficiency and usability, and indicated effect of anti-inflammation.
