Carbon tetrachloride ($CCl_4$)-induced liver injury depends on a toxic agent that has to be metabolized by the liver NAPDH-cytochrome P450 enzyme system to a highly reactive intermediate. Alternations in the activity of cytochrome P450 enzymes affect the susceptibility to hepatic injury from $CCl_4$. In this study, we evaluated the potential protective activity of the traditional Korean medicinal herb, Corni fructus (CF), against an experimental model of hepatotoxicity induced by $CCl_4$. The CF exhibited a hepatoprotective activity against $CCl_4-induced$ liver damage in Sprague-Dawley (SD) rats, as measured by GOT, GPT, ALP and histological observation. The CF also showed significant decrease of malodialdehyde (MDA) and increase of glutathion (GSH), catalase activity in rat liver homogenate. In addition, the expression of CYP2E1, as measured by reverse transcriptase-polymerase chain reaction (RT-PCR) and Western blot analysis, was significantly decreased in the liver of CF treated SD rats. But $CCl_4$ and CF has no significant effect on 1A1 and 3A1 isoform of cytochrome P450. Based on these findings, it is suggested that hepatoprotective effects of CF possibly related to antioxidative effects and regulation of CYP2E1 expression.

Cancer, which is expressed in various forms, is one of the leading causes of human death, Soamsan (SAS) is composed of ten medicinal herb, the prescription was made according to the principles of Oriental traditional medicine based on the concept of synergic effects and interaction of among the components. SAS has been used for the cancer therapy, but the mechanism of it's effect is not well known. In the present study, the cytotoxic effect of the SAS water extract on cancer cell lines was investigated by the method of MTT in A549 cell lines and the anti-angiogenic effect was shown in the assay of chorioallantoic membrane (CAM) and in the cornea of rat administerd orally with SAS water extraction. The viability of A549 cell lines was not affected by the whole extract of SAS but the n-Hexan fraction of SAS water extract showed strong cytotoxicity which was not seemed to be done by the apoptotic mechanism. SAS water extract showed inhibition effects of angiogenesis induced in the cornea of rat and CAM assay. As the above results, it is suggested that SAS can be a candidate for new prescription for cancer therapy.

Gastrodia elata has been widely used as a traditional medicinal herb. However, in Korean Pharmacopeia, neither a marker constituent nor an analytical procedure for G. elata has been established. In this study, we suggest gastrodin and gastrodigenin as marker constituents of G. elata, and propose an analytical procedure for simultaneous quantification of these constituents by high-performance liquid chromatography-ultraviolet spectroscopy (HPLC-UV). The analytical method was validated for its linearity, precision, accuracy, and specificity. Based on the validated method, gastrodin and gastrodigenin in 14 commercial G. elata samples were quantified.

Thirty five methanol extracts from 19 natural local plants, which have been used as traditional anti-cancer medicine, were prepared. They were analyzed the cytotoxic effects on primary fibroblast cells and carcinoma cells. The root extract of Solanum nigrum were highly toxic in both cell lines with $IC_{50}$ values of less than $0.01{\mu}g/{\mu}l$, and 26 of 35 extracts were toxic in all cells with $IC_{50}$ values of $0.1{\sim}2{\mu}g/{\mu}l$. Three extracts including the fruit extracts of Solanum nigrum and Morus alba had no cytotoxic activity in both cell lines. Five of 35 extracts were highly toxic in cancer cells than in primary cells. Because primary cells were more resistant on these extracts, the five extracts were selected for anti-cancer agent candidates. Apoptosis or programmed cell death has an essential role in chemotherapy-induced tumor cell killing. Recently, inducers of apoptosis have been used in cancer therapy. When two of 5 cancer cell-specific cytotoxic extracts (Ulmus parvifolia and Zelkova serrata) were treated in concentration of $0.02{\sim}0.1{\mu}g/{\mu}l$, apoptosis were increased at 3-5 times in cancer cell lines. Finally, the apoptotic effects of these extracts were confirmed by cleavages of both poly-(ADP-ribose)-polymerase and caspase-3 as apoptotic markers. In this report, we suggested that two of 35 medicinal herb extracts can be useful anti-cancer drug candidates inducing apoptosis in several carcinoma cell lines.

Aristolochic acid (AA) included in the plants Aristolochiaceae have been well known to be nephrotoxic and carcinogenic inducer and to cause renal disease such as Chinese Herb Nephropathy (CHN). In this study, we used a high performance liquid chromatopaphy-mass spectrometry (HPLC-MS) under the positive ion detection mode for the quantitative change of aristolochic acid-I and-II (AA-I and AA-II) in Aristolochiaceae (Aristolochia contorta Bunge, Aristolochia debilis Sieb. et Zucc., Aristolochia fangchi Wu), some related plants (Cocculus trilobus De candolle, Inula helenium Linne, Saussurea lappa Clarke), and its prescriptions (防己茯笭湯, 定喘散) with or without processing. Here, the processing methods and prescriptions in oriental medicine were generally used to alleviate toxicity or alter property of herbal medicines. However, the concentrations of AA-I and AA-II were highly determined in processed material extracts rather than unprocessed those, not measured in some related plants. Also, the concentrations of AA-I and AA-II even at the prescriptions mixed the plants of Aristolochiaceae were detected to range from 0.73 to 2.53 ppm. Thus, the present results suggest that the content of AA-I and AA-II contained to plants of Aristolochiaceae was not reduced by the processing methods or prescriptions which can induce the physico-chemical change and pharmacological transformation in traditional herbal medicines.

To provide the scientific corroboration of the traditional uses of Akebia quinata (Thunb.) Decne., a detailed analytical examination of A. quinata stems was carried out using a reversed-phase high performance liquid chromatography (RP-HPLC) method coupled to photodiode array detector (PDA) for the simultaneous determination of four phenolic substances; cuneataside D (1), 2-(3,4-dihydroxyphenyl)ethyl-O-${\beta}$-D-glucopyranoside (2), 3-caffeoylquinic acid (3) and calceolarioside B (4). Particular attention was focused on the main compound, 3-caffeoylquinic acid (3), which has a range of biological functions. In addition, 2-(3,4-dihydroxyphenyl)ethyl-O-${\beta}$-D-glucopyranoside (2) was considered as a discernible marker of A. quinata from its easy confuse plants. The contents of compounds 2 and 3 ranged from 0.72 to 2.68 mg/g and from 1.66 to 5.64 mg/g, respectively. The validation data indicated that this HPLC/PDA assay was used successfully to quantify the four phenolic compounds in A. quinata from different locations using relatively simple conditions and procedures. The pattern-recognition analysis data from 53 samples classified them into two groups, allowing discrimination between A. quinata and comparable herbs. The results suggest that the established HPLC/PDA method is suitable for quantitation and pattern-recognition analyses for a quality evaluation of this medicinal herb.

Objectives : Ma-huang is a traditional Chinese medicinal herb, derived from Ephedra sinica Stapf and other Ephedra species, used to treat asthma, nose and lung congestion, and fever with anhidrosis. It contains 0.5-2.5% by weight of total alkaloids, of which ephedrine accounts for 30 to 90%. Recently, Ma-huang has been used as a source of ephedrine in many dietary supplements formulated for the treatment of obesity, since ephedrine has been found to be effective in inducing weight loss in the obese. In this study the effects of the methanol extract of Ma-huang on the adipocyte of epididymal and brown fat pads in rats fed a high fat diet for six weeks were studied. Methods : Male Sprague Dawley rats weighing an average 94g (4 weeks old) were fed either a regular diet (RE) or a high fat diet (HF), and the HF group was subdivided into a Ma-huang methanol extract (30mg/100g body weight) group (HF+MH). The weight of epididymal fat pad and brown adipose tissue were measured. The cell size and cell number per unit area of epididymal fat pad were investigated. Results : The yield weight of methanol extract of Ma-huang was 3.63mg per l00g of Ma-huang. The body weight gain of the HF group was similar with that of the HF+ MH but higher than that of the RE. The weights of the epididymal fat pads and brown adipose tissue of the RE group were lower than those of HF and HF+MH groups. The cell sizes and numbers per unit area of epididymal fat pads of the RE and HF+MH groups were larger than those of HF group. The cell numbers per unit area size of epididymal fat pads were the smallest in the RE group. Conclusions : It could be concluded that the Ma-huang extract has no effect on the epididymal fat pads in rats fed a high fat diet and the clinical application of Ma-huang for the treatment of obesity should be re-considered.

Rhizoma Coptidis, a traditional herb medicine, has been used in Korea and China for many centuries as a treatment for many disease. The purpose of the present study was to determine the effect of Rhizoma Coptidis on histamine-induced tracheal smooth muscle contraction in guinea pigs and rats. Guinea pigs(500g, male) and rats(250g, male) were killed by $CO_2$ exposure and a segment (8-10mm) of the thoracic trachea from each guinea pig was cut into equal segments and mounted 'in pairs' in a tissue bath. Contractile force was measured with force displacement transducers under 0.5g loading tension. The dose of histamine which evoked 50% of maximal response ($ED_{50}$) was obtained from cumulative dose response curves for histamine ($10^{-7}-10^{-3}M$). Contractions evoked by histamine($ED_{50}$) were inhibited significantly by Rhizoma Coptidis. The mean percent inhibition was 33.2% after 1.5mg/ml Rhizoma Coptidis, and 69.5% after 5.0mg/ml Rhizoma Coptidis in guinea pigs, and the mean percent inhibition was 25.3% after 1.5mg/ml Rhizoma Coptidis, and 65.8% after 5.0mg/ml Rhizoma Coptidis in rats. Indomethacin ($10^{-7}M$) slightly but significantly attenuated the inhibitory effects of Rhizoma Coptidis. But propranolol and methylene blue ($10^{-7}M$) did not significantly alter the inhibitory effect of Rhizoma Coptidis. These results indicate that Rhizoma Coptidis can relax histamine-induced contraction of guinea pig and rat tracheal smooth muscle, and that this inhibition involves, in part, cyclooxygenese inhibitor.
