Objectives :The purpose of this study was to investigate the effect of Gentianae Radix on neurogenesis and apoptosis in ethanol- induced newborn rats hippocampus dentate gyrus. Methods :In vivo, laboratory animals were divided into three groups; Normal group(N), Control group(C) and Treated group (TG)(n=7 for each group). N were treated saline daily for five days. C were treated 1.5 g/㎏ ethanol and saline daily for five days. TG were treated 1.5 g/㎏ ethanol and 300 ㎎/㎏ Gentianae Radix daily for five days. BrdU(5-bromo-2-deoxyuridine) assay was used to test neurogenesis in the dentate gyrus. And TUNEL(Terminal deoxynucleotidyl transferase dUTP nick end labeling) assay was used to test apoptosis in the dentate gyrus. Three groups were measured body weight, serum ethanol concentration, BrdU-positive cells and TUNEL-positive cells in the dentate gyrus. In vitro, MTT(3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay was used to test viability in SK-N-MC cells. BrdU assay was used to test neurogenesis in SK-N-MC cells. DNA fragmentation and caspase-3 enzyme activity assay were used to test apoptosis in SK-N-MC cells. And treated ethanol and Gentianae Radix of all in vitro tests were made various concentration. Results :In vivo, Gentianae Radix modulated ethanol-induced neurogenesis and apoptosis in newborn rats hippocampus dentate gyrus. In vitro, TG 100 ㎍/㎖ have significantly modulated ethanol-induced neurogenesis and apoptosis in SK-N-MC cells. And only TG 100 ㎍/㎖ have significantly protected SK-N-MC cells from ethanol-induced cytotoxicity. Conclusions :Gentianae Radix may have the effect that modulated ethanol-induced neurogenesis and apoptosis in SK-N-MC cells.
