In vitro cytotoxic activities of cisplatin combined with Chungpesagan-tang or puerarin, which were treated with or without human intestinal bacteria, were measured. When cisplatin was combined with Chungpesagan-tang and its ingredient treated without intestinal bacteria, they did not affect the in vitro cytotoxicity of cisplatin against tumor cell lines. However, when cisplatin was combined with intestinal bacteria-treated Chungpesagan-tang and its ingredients, the cytotoxicities against SNU C4, L1210, A549 and P388 tumor cell lines were synergistically increased. Puerarin, which was isolated from Puerariae Radix, did not show in vitro cytotoxicity. However, its metabolite, daidzein, showed potent cytotoxicity against tumor cell lines and was synergistic by the combined usage of cisplatin. These results suggest that natural glycosides are not only prodrugs which can be transformed to active compounds by intestinal microflora, but the combined usage of cisplatin with natural components, such as daidzein, and herbal medicinal polyprescriptions, such as Chungpesagan-tang, may be a new method for prevention and minimization of the toxicity of cisplatin.

Objectives To evaluate that Okwada affected which factors for treatment of lung fibrosis. Methods Bleomycin induced lung fibrosis model made in mice. After Okwada lyophilized, power sample obtained and melt in distilled water. Okwada solution administered mice through oral route on 21 days after bleomycin instillation and this procedure performed once a day for 7 days. We divided by three groups; normal (control), bleomycin induced lung fibrosis without treatment (experimental), bleomycin induced lung fibrosis with treatment (treatment). On six weeks after bleomycin instillation, mice sacrificed and removed lung. We performed Western blot analysis for TGF-beta, phosphodiesterase 5A, interleukin (4,5,13) and compared therapeutic effects of Okwada. Results On western blot analysis, all normal and experimental mice detected TGF-beta, phosphodiesterase 5A, interleukin 4,5,13. The amount of band of TGF-beta, phosphodiesterase 5A, interleukin 5 in experimental and treatment group was similar. However, interleukin 4,13 of treatment group decreased compared with experimental group. Conclusions Okwada would be effected the lung fibrosis through suppression of interleukin 4,13.

Objectives : The aim of this study was to investigate effects of the Sungjuchunggan-tang(Xingjiuqinggan-tang), which has been used for alcoholic diseases in Oriental medicine, on alcoholic metabolism and alcoholic liver damage. Methods : We evaluated the activities of alcohol dehydrogenase(ADH)and aldehyde dehydrogenase(ALDH), and measured the levels of AST, ALT, glucose, triglyceride, HDL-cholesterol, LDL-cholesterol and phospholipid in serum of guinea pigs. Results and Conclusions : In this experiment, Sungjuchunggan-tang, Pharbitidis Semen and Puerariae Radix significantly suppressed the activity of ADH which is a precursor enzyme of acetaldehyde. Sungjuchunggan-tang and Pharbitidis Semen significantly suppressed the activity of ALDH, which is a catabolic enzyme, and increased its level. Due to alcohol consumption, level of ALT and AST were significantly reduced. These experimental results suggest that Sungjuchunggan-tang and Pharbitidis Semen inhibit the formation of acetaldehyde in the metabolism of alcohol, and affect the recovery of weakened liver functions caused by alcohol.

Interaction between epidermis and dermis plays an important role in wound healing and hair follicle formation. This study focused on investigating the potency of ethanol extract of Puerariae Radix (EPR) as cosmetic ingredient using human dermal fibroblasts (hDFn). Our results revealed that EPR suppressed collagenase activity dose-dependently. EPR inhibited activity of $5{\alpha}$-reductase I and II at the final concentration of $25{\mu}g/ml$ in hDFn cells. Also, EPR promoted the proliferation and the ERK activation of cells. ERK phosphorylation by EPR was blocked by specific inhibitor of ERK, PD98059. EPR-induced cell proliferation was blocked by PD98059. This means that EPR could promote the proliferation of hDFn cells via the activation ERK. Collectively, these results suggest that EPR may be used as a new cosmetic ingredient.

Ssangwhatang which has been known to have antipyretic, analgesic and antifatigue effects are composed of Paeoniae Radix, Angelicae gigantis Radix, Astragali Radix, Rehmaniae Radix, Cnidii Rhizoma, Cassiae Cortex, Glycyrrhizae Radix and Puerariae Radix. Effects of some formulations of Ssangwhatang were studied with respect to the analgesic, antipyretic, hypothermic, anticonvulsive and antiinflammatory actions in experimental animals. The results obtained were as follows: 1) Prescription A, B, C and D of Ssangwhatang were showed significant analgesic effect by the acetic acid stimulating method in mice. 2) All Ssangwhatang-prescriptions used in this studies had hypothermic effect in normal mice. 3) Significant antipyretic effect in febrile rabbits were recognized in prescription A and C of Ssangwhatang, while not in prescription B and D of Ssangwhatang. 4) Prescription A, B, C and D of Ssangwhatang showed marked antiinflammatory effect against the edema induced by carrageenin in rats. 5) Prescriptions of Ssangwhatang did not show significant anticonvulsive effect against the convulsion induced by picrotoxin and strychnine in mice. From the above results, analgesic, hypothermic, antipyretic and antiinflammatory effects were recognized in Ssangwhatang. Ssangwhatang A- and C- prescriptions added with Pueraiae Radix showed better effects than prescription B and C of Ssangwhatang.

Excessive or long term ingestion of alcohol may cause hepatitis, cirrhosis, hepatic tumor and so on. Aldehyde and active form of free oxygen that are metabolites of alcohol in liver are the cause of liver cell damage. The main system of alcohol metabolism is composed of alcohol dehydrogenase (ADH), aldehyde dehydrogenase (ALDH) and cytochrome P450. In connection with in vivo alcohol metabolism, more than one hundred natural products were screened for inhibition or activation of alcohol dehydrogenase. As a results, we found significant inhibition ($IC_50$) of ADH by methanolic extracts of Puerariae Radix ($61.2{\;}\mu\textrm{g}/ml$), Glycyrrhizae Radix ($105.0{\;}\mu\textrm{g}/ml$), Cinnamomi Ramulus ($7.0{\;}\mu\textrm{g}/ml$), Rhei Rhizoma ($36.7{\;}\mu\textrm{g}/ml$), Mori Cortex Radicis ($106.2{\;}\mu\textrm{g}/ml$), Chrysanthemi Flos ($112.2{\;}\mu\textrm{g}/ml$), Erycibes Caulis ($36.7{\;}\mu\textrm{g}/ml$), and Scutellariae Radix ($122.5{\;}\mu\textrm{g}/ml$)
