  • Many medicinal plants have been used for the treatment of edema, jaundice, and gonorrhea in traditional Oriental medicine. This screening study was designed to search the positive inotropic effects of herbal extracts in beating rabbit atria. Aquarius extracts of twenty six herbs were examined in atrial mechanical dynamics such as pulse pressure and stroke volume and atrial natriuretic peptide (ANP), one of the main hormones involved in the regulation of the body fluid and blood pressure homeostasis in perfused beating rabbit atria. Sophora flavescens Ait., Rheum officinale Baill., Acorus gramineus Sol., Chelidonium majus L., Pulsatilla koreana Nakai., Reynoutria japonica Houtt., Euphorbia lathyris L., Pyrrosia lingua (Thunb.) Farwell, Poncirus trifoliata Rafin., Anemarrhena asphodeloides Bunge, Kochia scoparia Schrad. significantly increased stroke volume and pulse pressure. However, those herbal extracts were not induced ANP secretion. We clarified the eleven herbal extracts for the positive inotropic effect independent of ANP secretion in beating rabbit atria. Thus these results provide a beneficial data for the treatment of the impairment of body fluid and blood pressure in traditional Oriental medicine.

  • This study had been done for the investigation of the effect of Vitis vinifera extract(V), Schisandra chinensis extract (S), Taraxacum officinale extract (T), Gardenia jasminoides extract (G), Angelica acutiloba extract (A) and Paeonia japonica extract (P), and their mixtures on the antioxidant and ethanol oxidation system which was induced by Lieber-DeCarli ethanol liquid diet. Male Sprague-Dawley rats were randomly divided into eight groups: ethanol diet (ED), normal diet (ND), ED+V (100 mg/kg/day), ED+S, ED+T, ED+G, ED+A and ED+P (300 mg/kg/day). We studied the effect on alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) after herbal extracts administration for 6 weeks in rats induced by Lieber-DeCarli ethanol liquid diet. The differences in ADH and ALDH activity of the rats treated with herbal extracts and ED group were not significant. Phase I enzyme activity was found to be significantly higher in the ED+V than the ED group. Phase II enzymes (glutathione-S-transferase, phenol sulfatransferase) activities were found to be higher in the herbal extracts than the ED group. Herbal extracts not only reduced ethanol-induced elevation of level malondialdehyde but also protected against ethanol-induced decrease of reduced glutathione, gluthione reducatse, glutathione peroxidase, catalase and superoxide dismutase activities. Therefore, they can be utilized as a health functional food or new drug candidate for fatty liver and hepatotoxicity which was induced by chronic alcohol consumption.

  • Objectives : Aconiti Lateralis Preparata Radix (Aconitum Carmichaeli, AC) and Cinnamomi Cortex (Cinnamomi Cortex, CC) have been treated to elderly for kidney yang enhancement in Korean traditional medicine. In this study, the effects of water extract of AC and CC on RANKL (Receptor Activator for Nuclear Factor ${\kappa}B$ Ligand)-induced osteoclast differentiation were evaluated in culture system. Methods : MTT assay was used to evaluate the potential cytotoxicity of AC and CC extracts in bone macrophage marrows (BMMs) stimulated with M-CSF. TRAP (tartrate-resistant acid phosphatase) staining and TRAP activity were performed to know the inhibitory effect on osteoclast differentiation. The protein expression levels of nuclear factors such as activated T cell(NFAT)c1, c-Fos, MAPKs and ${\beta}$-actin in cell lysates treated with AC and CC extracts were analysed by western blotting. Results : AC, CC extracts and their co-administration inhibited significantly RANKL-induced osteoclast differentiation in BMMs in a dose dependent manner without toxicity. Each AC and CC extracts inhibited the phosphorylation of p38. Also, AC and CC extracts, respectively, inhibited the protein expression of c-Fos and NFATc1 more than Co-administration of AC and CC even if all treatments did. It was observed that RANKL-induced degradation of I-${\kappa}B$ is significantly suppressed by all treatments. Conclusions : Taken together, It was concluded that AC and CC have beneficial effect on osteoporosis by inhibition of osteoclast differentiation. Thus, Atractylodis AC and CC could be a treatment option for osteoporosis.

  • In this experiment, we show the effects of herbal plant extracts on the production of nitric oxide (NO) and TNF-$\alpha$. The extracts of Angelica gigas, Astragalus membranaceus, Acanthopanax sessiliflorus and Houttuynia cordata had no effect on NO synthesis by itself in mouse macrophage cell line (RAW264.7). However, the stimulation with these extracts in the presence of murine interferon-${\gamma}$(mIFN-${\gamma}$) resulted in increased NO synthesis. When these extracts were used in combination with mIFN-${\gamma}$, there were a marked cooperative induction of NO and TNF-$\alpha$ synthesis in a dose-dependent manner. The same results were obtained in the mouse peritoneal macrophages used. The optimal concentration of these extracts on NO synthesis was shown at 100$\mu\textrm{g}$/mL with 100U/mL of mIFN-${\gamma}$. NO synthesis was inhibited by NG-monomethyl-L-arginine. When cell lines were treated with extracts, the expression of inducible NO synthetase (iNOS) was markedly increased in RT-PCR analysis. In addition, synergy between mIFN-${\gamma}$ and extracts was dependent on extracts-induced tumor necrosis factor-$\alpha$(TNF-$\alpha$). These results suggest that water extracts of herbal plants can induce iNOS, NO and TNF-$\alpha$ synthesis of mouse macrophage cell line (RAW264.7) and peritoneal macrophages in combination with mIFN-${\gamma}$.

  • Objectives : Since single extract powders was released at 1987, the insurance fee has not been changed, but the price of raw material has been increasing. According to this, Pharmaceutical company couldn't invest on quality of the product, so, the quality of single extracts went down and lost the consumer's trust. We checked the contents of marker ingredients in single extract thereby to recover the reliability of insurance-covered herbal preparations. Methods : we bought total twelve products of eight different single extracts of two main pharmaceutical companies among total 65 kinds of single extract powder stipulated in KHP (The Korean Herbal Pharmacopoeia) monograph III at Jan. 2013. Assays of selected single extract powders are performed by KHP regulation. And we surveyed price fluctuation of relevant herb raw materials from 2005 to 2012. Results : Among twelve products, eight single extract powders were suitable by the KHP regulation. But four products didn't reach the content amount of KHP. Marker contents in the single extracts product of Pueraria Root, Licorice, Peony root and Scutellaria Root of A company were 70%, 1%, 23.7% and 75.1%, respectively. Conclusions : We can acertain whether there's a quality problem in the insurance-covered single extract powders. But, A company is no longer producing these improper single extract powders. As a medicine, single extract powders needs to be strictly quality controlled by the company, and regularly monitored by the KFDA.

  • Objectives : To find antipruritic herbal medicines, we screened the water extracts of four herbal medicines which have been frequently prescribed to treat dermatologic diseases in oriental medicine. Methods : Water extracts of Bupleuri Radix, Scutellariae Radix, Cimicifugae Rhizoma and Puerariae Radix were administered at a dose of 300 mg/kg to male ICR mice. 1 hour later, serotonin hydrochloride dissolved in physiologic saline at a concentration of 100 nmol / 50${\mu}{\ell}$ was administered intradermally to the nape of the neck at a dose of 50${\mu}{\ell}$. Then the scratching behavior was observed. Dry skin pruritus was induced with cutaneous application of acetone / ether (1:1) mixture and water (AEW) to the rostral back of male ICR mice, twice a day for 5 days. 14 hours after the last application, the most effective material in the first experiment was administered perorally at doses of 75, 150, 300, 600 and 1200 mg/kg. 1 hour later, the scratching behavior was observed. Results : Water extracts of Puerariae Radix significantly inhibited the serotonin-induced scratching behavior and the mean of scratching bouts was reduced by half compared with the control group. Bupleuri Radix group also showed a 29% decrease in the mean of scratching bouts, but there was no statistical significance. Water extracts of Puerariae Radix also inhibited the AEW-induced scratching behavior, in a dose-dependent manner. The dose of 150 mg/kg showed the highest and statistically significant antipruritic effect. Conclusions : These results suggest that Puerariae Radix and its constituents have antipruritic effect, and are new candidates as antipruritic agents.
