초록
The present study was conducted to evaluate the primary dermal irritation and sensitization of DCS(the mixture extract of black soybean(β-sitosterol), mori cortex Radix and polygoni multiflori Radix) when tested by the guinea pig maximization test(GPMT) and Freund's complete adjuvant test with an identical, intradermal induction concentration. In primary skin irritation test, 10, 20, 40% of DCS with a volume of 0.4 ㎖ was applied to intact and abraded skins, respectively, for 24 hrs in 6 healthy male New Zealand White rabbits. 10, 20, 40% of DCS did not induced any adverse reaction such as erythema and edema on intact and abraded skins. So, DCS was evaluated to be a 'non-irritant' material. In skin sensitization study, guinea pigs were sensitized with intradermal injection of 0.1 ㎖ DCS compound for 24 hrs. After 1 week, DCS was treated on the site of injection, and challenged 2 weeks later. 10%, 20% DCS were graded as a weak material from 0 in both sensitization score and rate. Based on these results, it is suggested that 20% DCS does not cause contact irritation and sensitization.
