본 실험은 황금열수추출물이 알레르기성 접촉 피부염 유발 시 항산화활성, serum Ig E농도와 표피회복능에 미치는 영향을 조사하기 위해 행해진 것으로 1-chloro-2,4-dinitrochlorobenzene(DNCB: 2.5% DNCB 1 mL로 감작, 4일 경과 후 1% DNCB 1 mL로 유발) 처리로 알레르기성 접촉 피부염이 유발된 Sprague Dawley rat 수컷 흰쥐에 황금열수추출물(1 mL/kg/day)을 경구투여한 다음 혈장과 간의 항산화활성, 혈중 Ig E 농도, 표피두께변화를 관찰하였다. DNCB 처리에 의해 지질과산화물 함량과 Ig E 농도, 표피두께가 증가하였으며 황금열수추출물의 경구투여에 의해 간의 지질과산화물 함량 감소, 혈중 Ig E 농도 감소, 표피두께가 저하되는 결과를 보였다. 이상의 결과로 미루어 황금열수추출물이 알레르기성 접촉피부염으로 유발된 rat의 체내 항산화활성과 Ig E 농도개선, 표피두께 개선에 효과가 있는 것으로 생각된다.
After allergic contact dermatitis (ACD) elicited by application of 1 mL of 2.5% 1-chloro-2,4-dinitrochloro-benzene (DNCB) onto dorsal skin, Sprague Dawley male rats fed Scutellaria baicalensis water extract were observed to investigate the mitigative effect of Scutellaria baicalensis water extract on ACD. The Scutellaria baicalensis water extract (100 mg/kg/day) was daily administered to rats suffered from ACD. Concentrations of TBARS in plasma and liver were increased in rats with ACD. The concentrations of TBARS in liver were significantly decreased in Scutellaria baicalensis-fed group (SBFG) compared to control group (CG), but not in plasma. Liver SOD activity was significantly increased in SBFG compared to that of normal group and CG. Serum Ig E level was significantly increased in CG compared to normal group, while that of SBFG was significantly decreased. The epidermal thickness of CG was significantly increased compared to that of normal group, while that of SBFG was significantly decreased compared to that of CG. These results indicated that the Scutellaria baicalensis water extract administration was effective for antioxidative activity in liver, serum Ig E level and epidermal thickness of rats with ACD.
