Objectives and Methods : In order to elucidate toxic mechanism of myocardial damage and protective effect of myrrha water extract against cytotoxic effect of xanthine oxidase/hypoxanthine(XO/HX), cardioprotective effect of myrrha water extract was examined by MTT assay, LDH (Lactate Dehydrogenase) activity and heart beating rate after cultured myocardial cells derived from neonatal mouse were treated with various concentration of XO/HX, a free radical. Results : XO/HX induced a decrease of cell viability, an increase in the amount of LDH, and a decrease of heart beating rate on cultured myocardial cells in a dose-dependent manner. In cardioprotective effect of myrrha water extract, it showed a decrease in the amount of LDH and an increase of heart beating rate on cultured myocardial cells damaged by XO/HX. Conclusions : From the above results, it is suggested that XO/HX showed toxic effect in cultured myocardial cells derived from neonatal mouse and that myrrha water extract is very effective in the prevention of XO/HX-induced cardiotoxicity.

The purpose of this research was to investigate cytotoxity of Sunbanhwalmyungeum extract. Cytotoxity was determined by MTT assay method. After tumor cell lines(G361, BI6F10, MDA, A549) transplantation, the extracts of SunBangHwalMyungEum and its composition oriental medicines were administered, cytotoxity was measured by absorbance. The results were obtained as follows. 1. Sunbanhwalmyungeum extract and its composition oriental medicines extracts showed the concentration was higher, the more cytotoxity increased. 2. Both water and ethanol extracts of Sunbanhwalmyungeum showed excellent cytotoxity against G361, B16F10, MDA, A549 and high cytotoxity over 80$\%$ against G361, B16F10, MDA except A549 at the concentration of 1000ppm. 3. In water extract, Rhei Radix et Rhizoma, Gleditsiae Spina, Trichosanthis Radix, Glycyrrhizae Radix, Ledebouriellae Radix showed excellent cytotoxity. In ethanol extract, Gleditsiae Spina, Citri Pericarpium, Trichosanthis Radix, Paeoniae Radix Rubra, Myrrha showed excellent cytotoxity. 4. Rhei Radix et Rhizoma, Gleditsiae Spina, Trichosanthis Radix, Paeoniae Radix Rubra showed high cytotoxity in both water and ethanol extrats. 5. In water extract, Glycyrrhizae Radix, Ledebouriellae Radix, Myrrha showed high cytotoxity against A361, Lonicerae Flos, Olibanum, Fritillariae cirrhosae Bulbus, Paeoniae Radix Rubra, Manitis Squama against B16F10, Paeoniae Radix Rubra, Manitis Squama against MDA, Rhei Radix et Rhizoma, Angelicae gigantis Radix against A549. 6. In ethanol extract, Lonicerae Flos, Trichosanthis Radix showed high cytotoxity against G361, Rhei Radix et Rhizoma, Angelicae gigantis Radix, Gleditsiae Spina, Olibanum, Angelicae dahuricae Radix, Fritillariae cirrhosae Bulbus, Paeoniae Radix Rubra, Glycyrrhizae Radix, Ledebouriellae Radix, Myrrha against B16F10, Rhei Radix et Rhizoma, Manitis Squama against MDA, Citri Pericarpium, Manitis Squama against A549.

To test the protective effect of herbal medicine against oxygen free radical-induced myocardiotoxicity, cytotoxicity of xanthine oxidase/hypoxanthine (XO/HX) was examined using MTT, TBARS, and beating rate assay in the presence of water extract of Sujeom-san(SJS) or single consituents of its prescription. Myocardial toxicity was evaluated in neonatal rat myocardiocytes in cultures. In the present paper, XO/HX resulted in a decrease in viability and beating rate and increases in lipid peroxidation in cultured myocardial cells. In the effect of SJS water extract, it showed effects from the cardiocytotoxicity induced by XO/HX treatment such as increases in beating rate and decreases in lipid peroxidation. In the effect of Rhizoma Corydalis (RC), Faeces Trogopterori (FT), Fructus Amomi Tsaoko (FAT) and Myrrha on the cardiocytotoxicity, they were significantly effective in blocking the XO/HX-induced cardiocytotoxicity by increase of beating rate in FAT and FT group as well as decrease of lipid peroxidation in FT and RC group. These results show that oxygen free radical elicits toxic effects in cultured myocardial cells derived from neonatal rat, and suggest that water extract of Sujeomsan, Rhizoma Corydalis, Faeces Trogopterori, Fructus Amomi Tsaoko or Myrrha is very effective in the prevention of xanthine oxidase/hypoxanthine- induced cardiotoxicity.

Objectives : Commiphora myrrha (CM) has been used in traditional medicine for treating disease such as obesity, hyperlipidemia, atherosclerosis, diabetes and osteoarthritis. However, the protective effects of CM on acute pancreatitis (AP) has not been reported. Thus, the aim of this study was to evaluate the protective effects of CM water extract on cerulein-induced AP. Methods : AP was induced in mice via intraperitoneal injection of supramaximal concentrations of the stable cholecystokinin analogue cerulein ($50{\mu}g/kg$) every hour for 6 times. Water extract of CM (0.1, 0.2, or 0.5 g/kg) was administrated intraperitoneally 1 h prior to the first injection of cerulein. The mice were killed at 6 h after the final cerulein injection. Pancreas was rapidly removed for morphologic and histochemical examination, myeloperoxidase (MPO) assay. Blood samples were taken to determine serum amylase and lipase activities. Results : Administration of CM significantly inhibited pancreatic weight/body weight ratio, pancreas histological injury. And CM administration inhibited the serum digestive enzyme elevation such as amylase and lipase on cerulein-induced pancreatitis. In addition, Pancreas MPO activity which indicates neutrophil infiltration was inhibited by CM extract on cerulein-induced pancreatitis. Conclusions : In conclusion, our results could suggest that pre-treatment of CM reduces the severity of cerulein-induced AP. Therefore, CM could be used as a protective agent against AP. Also, this study could give a clinical basis that CM could be a drug or agent to prevent AP.
