Abstract

|
|
|
In order to evaluate the effect of Ginseng Radix(GR) against endocrine disrupting chemicals(EDC), cultured mouse osteoblasts were preincubated with various concentrations of GR extract before the exposure of Bisphenol A for 12 hours. Cytotoxic effect of Bisphenol A was measured by the XTT assay. In addition, the protective effect of GR over Bisphenol A-induced cytotoxicity on osteoblasts was assessed by the DNA and protein synthesis in these cultures. The results were as follows : Osteoblastic cell viability was decreased in dose and time dependent manner after exposed to various concentrations of Bisphenol A. Midcytotoxicity value(MCV50) of Bisphenol A was determined at 6μM Bisphenol A after osteoblasts were grown for 12 hours in the media containing various concentrations of Bisphenol A. Amount of DNA synthesis was increased in dose-dependent manner after cultured osteblasts were pretreated with GR for 2hrs before exposure to Bisphenol A for 12 hours. Amount of protein synthesis was increased in dose-dependent manner after cultured osteoblasts were pretreated with GR for 2 hours before exposure of Bisphenol A for 12 hours. From these results, it is suggested that Bisphenol A was highly toxic by the decrease of the cell viability, and GR is effective in the prevention of Bisphenol A-induced cytotoxicity by the increase of DNA and protein syntheses in cultured mouse osteoblasts.
