두충 추출물이 DNCB로 유발된 알레르기성 접촉피부염과 산화적 손상에 미치는 영향

국문 초록 (Abstract)

두충(잎, 껍질, 줄기)의 추출물이 DNCB로 감작된 4주령 BALB/c mouse 암컷에 유도된 접촉성 피부염의 억제효과를 조사하였다. 림프절, 비장 및 흉선의 무게는 두충 투여군이 DNCB 대조군보다는 낮게 나타났다. 두충 부위별 추출물을 투여한 군에서 귀의 무게는 두충 추출물의 농도가 높을수록 감소하는 경향을 보였으며, 대조군과 비교하여 무게에 함량변화가 있었다. 두충의 부위별 추출물을 1,000 ㎎/㎏ 농도로 투여하면 귀의 무게는 대조군과 유사한 수준까지 낮아졌으며, 귀의 두께는 두충 추출물을 투여한 군에서 시간이 경과할수록 두께가 감소하는 경향을 나타내었다. MDA 함량은 DNCB 대조군과 두충 투여군을 비교하였을 경우에, 간 조직에서 차이가 나타나지 않았으나, 염증이 발생한 귀 조직에서는 차이가 나타났으며(p＜0.05), NO 함량은 SW, ST 및 BT 그룹에서 염증이 억제되어 대조군과 마찬가지로 측정되지 않았다.

다국어 초록 (Multilingual Abstract)

Inhibitory effects of allergic contact dermatitis of hot water extract of Duchung (Eucommia ulmoides Oliver) leaf, bark and stem growing at Sancheong-gun were investigated for female BALB/c mouse induced by repeat elicitation of DNCB (2,4-dinitro-chlorobenzene). Skin reactions, consisting of increased ear thickness and the presence of ear inflammation, were observed in mice treated with DNCB and Duchung. Weight of lymph node, spleen and thymus in mice treated with Duchung extracts were lower than that of mouse treated with DNCB. Ear weight of mouse treated with Duchung extracts was decreased by increasing the concentration of sample as compared to control group and dropped as low as control level at 1,000 ㎎/㎏. Ear thickness became thinner as test time on Duchung extract progressed. MDA (malondialdehyde) contents in liver tissue were not different in sample group with DNCB group, but were different in ear tissue. NO (nitric oxide) contents was decreased in Duchung extract groups at serum and ear tissues as compared to 1% DNCB group. In the present study, the results suggested that Duchung extract inhibits inflammatory response and oxidative damage induced DNCB allergen.
