<><FONT size=5>银屑病表皮的病理生理特点是增生过快和分化不全,雌激素周期的小鼠阴道上皮增生活跃,有丝分裂增多,细胞转换加快,模拟了银屑病表皮增生过快的特点。而鼠尾鳞片表皮的角化缺少颗粒层形成的过程,模拟了银屑病表皮角化不全的特点。有人认为银屑病与机体免疫功能异常有关。我们采用上述二种动物模型试验了镇银膏对银屑病的治疗作用。结果表明,镇银膏高、中、低剂量对小鼠及大鼠阴道上皮细胞有丝分裂均有明显的抑制作用;高、中剂量对小鼠尾鳞片颗粒细胞层的形成有明显的促进作用,低剂量作用不明显与空白对照组比较无显著性差异。镇银膏也可明显提高小鼠外周血<FONT face="Times New Roman">T</FONT>淋巴细胞的活性并可非常显著的增强小鼠<FONT face="Times New Roman">NK</FONT>细胞杀伤靶细胞的活性。</FONT></P></TD></TR></TABLE></FONT>
