The Effect of Saingheylyunbooemgami Extract to Revover Function of Stratum Corneum on Mice Model after Atopic Dermatitis Elicitation.

生血潤膚飮加味方이 아토피 피부염을 유발한 동물모델의 각질층 기능회복에 미치는 영향

Introduction and Objectives : Applying the saingheylyunbooemgami(SY) extract on to the atopic dermatitis(AD) is to study change of external dermal formation, change of leukocytes in vasculature, change of lipid formation in stratum corneum and distribution of ceramide and this study is done through forcing injury to rat's back skin which are lipid protect formation in stratum corneum. Materials and Methods : The AD which caused intentionally using the external application on the rat's back skin was used the SY. The change of leukocytes in vasculature has been identified through optima 5.2 and student t-test and the results were made into dermal foramtion graph. Results : After dispensing SY extract into the AD, the dermal injury was decreased, Especially, recover of lipid protection formation which include lipid and ceramide in stratum corneum is suppressing acute inflammation that some factors are PKC, TNF-${\alpha}$, lL-12B which controled the secretion of relating inflammatory cytokine, also went onto decrease of angiogenesis, and the decrese of degranulated mast cell. In addition, the decrease of epithelial injury also caused the growth of cell to decrease in stratum basale and cytoclasis. In the vasculature. the leukocytes were also decreased and it could relate to decrease AD. Conclusions : Thus. SY has effect on AD suppressing the dermal injury through recovering of lipid protection formation in stratum corneum.
