Effects of Capparis Spinosa Total Alkaloid on Vascular Endothelial Growth Factor, Endothelin-1 and Soluble Vascular Cell Adhesion Molecule-1 Levels in Mice with Systemic Sclerosis / 医药导报

ABSTRACT

Objective To observe the effects of Capparis spinosa total alkaloid on vascular endothelial growth factor (VEGF),endothelin-1(ET-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) levels in systemic sclerosis (SSc) mouse model and explore the therapeutic mechanism of Capparis spinosa total alkaloid for the treatment of SSc. Methods A total of 90 BALB/c mice were randomly divided into blank control group,model control group,penicillamine (125 mg·kg-1) group and Capparis spinosa total alkaloid low(225 mg·kg-1),medium(450 mg·kg-1) and high(900 mg·kg-1) dose group. Except for the blank control group,SSc mouse model was established by daily subcutaneous injection of bleomycin in the back of the mice.After establishing model successfully,Capparis spinosa total alkaloid emulsifiable paste was externally applied with Capparis spinosa total alkaloid group,ground substance was externally applied to the mice in blank control group and model control groups,penicillamine was intragastrically administrated in the penicillamine group for 60 days,once daily.After the treatment,the content of VEGF in skin tissue and ET-1,sVCAM-1 in serum were measured by ELISA. Results The levels of VEGF and ET-1 were significantly decreased in Capparis spinosa total alkaloid high dose group as compared with model control group(P<0.05, P<0.01),but the content of sVCAM-1 wasn't influenced(P>0.05). Conclusion Capparis spinosa total alkaloid is effective in adjusting abnormal expression of VEGF and ET-1 in SSc mice.
