ABSTRACT

To evaluate the effect of Yuldahansotang(YHT) water extract on cultuted mouse spinal sensory neuron which was inhibited by xanthine oxidase(XO) and hypoxanthine(HX)-induced oxigen radicals, MIT assay, NR assay, Neurofilament enzymeimmuno assay and LDH activity assay were carried our after the cultured mouse spinal sensory neuron were preincubated with various concentrations of YHT water extract for 3 hours prior to exposure of XO/HX. The results obtained were as follows: 1. XO/HX, a oxigen radical, decreased the survival rate of the cultured mouse spinal sensory neuron cells on NR assay and MTT assay. 2. MTT50 value and NR50 value pf XO/HX were 20 mU/ml XO/0.2 mM HX and 40 mU/ml XO/0.2 mM HX. 3. YHT water extract have efficacy of increasing neurofilament. 4. YHT water extract have efficacy of increasing LDH activity. From above the results, It is concluded that YHT has marked efficacy as a treatment for the damages caused in the XO/HX-mediated oxidative process.
