N/A Objectives : To examine the cytotoxicity of streptomycin(STR) on cultured mouse fibroblasts, cytotoxocity-induced by STR was measured by MTT assay. Methods : Fibroblasts were cultured in the media containing various concentrations of STR for 72 hours. In addition, cytoprotective effect of Drynariase Rhizoma(DR) on STR-induced cytotoxicity in fibroblasts was examined when fibroblasts were preincubated with various concentrations of DR for 2 hours before treatment of 5 ㎍/ml STR for 72 hours. Results : STR decreased remarkably cell viability in a dependentmanner in these cultures, and also DR increased cell viability and amount of DNA synthesis damaged by STR. Conclusions : From the above results, it is suggested that STR has toxic effect in cultured mouse fibroblasts, and also DR was effective in the protection of STR-induced cytotoxicity in these cultures.

The cytotoxic and antitumor activity of Herba cratalariae sessiliflorae on cultured NIH 3T3 fibroblast and human oral epitheloid carcinoma cells were evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazoliumbromide (MTT) colorimetric method. The light microscopic study was carried out to observe morphological changes of cultured mouse fibroblast and human oral epitheloid carcinoma cells (KB). These results were obtained as follows; Ethyl acetate, chloroform and hexane extracts showed a significant cytotoxicity in NIH 3T3 fibroblast, but the other extracts did not show. All extracts exhibited a significant antitumor activity in human oral epitheloid carcinoma cells, but ethanol extract did not show a antitumor activity. Hexane extract showed low cytotoxic effect, but exhibited the most antitumor activity. The MTT absorbance in NIH 3T3 fibroblast was significantly decreased by treatment with chloroform, ethyl acetate and hexane extracts respectively. Human oral epitheloid carcinoma cells was significantly decreasd by treatment with all extracts with the exception of ethanol extract. The difference in MTT absorbance in two cell Types was most remarkable when treated with water and hexane extracts. Cholroform and hexane extracts showed the strongest effect in growth inhibition of human oral epitheloid carcinoma cells. These results indicated that water extract possessed no cytotoxicity and a strong antitumor activity.

N/A Objective : To evaluate the effect of Semen Armeniaceae Amarum (SAA) on allergy, studies were done experimentally. Methods : After induction of allergic inflammation asthma by treatment of ovalbumin, water extract from SAA were taken orally for five successive days on mice respectively. We were measured in BALF, serum IgE, FCA on the biochemical change associated with allergy. Results : In the total cell of BALF, the SAA extract 48Omg/kg treated group was significantly reduced compared to control group and the reduction of eosinophil showed significantly at concentration of 240, 48Omg/kg. The SAA extract (480mg/kg) group was significantly decreased compared to control group on IgE antibody formation. SAA dose-dependently also significantly inhibited to passive cutaneous anaphylaxis(PCA) activated by anti - dinitropheny 1 (DNP) IgE. Conclusions : These results indicate that Semen Armeniaceae Amarum showed benefical effect on the allergic asthma.

N/A Objective : To evaluate effect of allergy by Tripterygiwn regelii (TR), the biochemical changes associated with allergy were measured in BALF. serum splenocyte and lung of mice. Methods : After induction of allergic inflammation asthma by treatment of ovalbumine, water extracts from stem and leaf (SL) or flower (FL) of TR were taken orally for five successive days on mice, respectively. Result : In the total cell of BALF. the SL-TR extract (lCKhwk, h.w)-treated group was significantly reduced compared to control level and the reduction of eosinophil showed significantly at concentraton of 360 and loo0 dks, b.w. On the other hand, substantial decrease in IgE antibody formation was significantly observed by administration with SL-TR extract, whereas IgGZa was not affected. IgCl antibody formation appeared to be decreased inserum from SL-TR treated mice(l000 mg/kg, b.w). The content of IL-4 exhibited physiological role in splenocyte and lung was significantly reduced in the examined group compared to that of control after treatment of SL-TR extract(l@X/kg, b.w). In the case of IL-5, however, it was significantly reduced by FL-TR extract. In addition, IL-5 content in splenocyte was significantly reduced at concentration of 360 and loo0 d k g . b.w. by SL-TR dose, respxtively, and that of lung was significantly reduced dose-dewndently(l20, 360 and 1000mp/kg, b.w). Cnnclusion : It could be conduded that TripteTygiwn regelii showed beneficial effect on the allergic asthma and especially, its leaf and stem is more effective than flower.

N/A Objectives : To clarify the myocardial toxicity of FeSO_4 in cultured rat myocardial cells, toxic effect was measured by MTT assay. Methods : Myocardial cells were incubated for 12hours in the media containing 10~80㎛ concentrations of FeSO_4. And also, the protective effect of Alli Macrostemi Bulbus(AMB) was measured in these cultures. Results : Cell viability was remarkably decreased in a dose- and time-dependent manners when cultured myocardial cells were exposed to 40 ㎛ FeSO_4 for 12hours. In the cytoprotective effect of AMB on FeSO_4-induced cytotoxicity, AMB blocked the FeSO_4-induced myotoxicity in these cultures. Conclusions : From the above results, it is suggested that FeSO_4 is toxic on cultured rat myocardial cells and AMB is effective in the prevention of FeSO_4-induced myocardial toxicity.
