><FONT size=5><B >摘要</B><FONT face="Times New Roman"> </FONT>银屑病(牛皮癣)为常见的皮肤病之一;目前尚未有理想的治疗药物。我们曾应用<FONT face="Times New Roman">Bonder</FONT>和<FONT face="Times New Roman">Van Scott</FONT>提出的鼠尾磷片表皮模型<FONT face="Times New Roman">Jarrett</FONT>和<FONT face="Times New Roman">Spearman</FONT>提出的小鼠阴道上皮模型证实,镇银膏对小鼠及大鼠阴道上皮细胞有丝分裂均有明显抑制作用,对小鼠尾磷片颗粒细胞层的形成有明显的促进作用,显示镇银膏对银屑病有治疗作用。为探讨镇银膏抗银屑病的作用机理,我们的试验也证实镇银膏能明显提高小鼠外周血淋巴细胞活性,并可显著增强小鼠<FONT face="Times New Roman">NK</FONT>细胞杀伤靶细胞的活性。说明镇银膏有免疫调节作用。为进一步证明镇银膏的免疫调节作用机理,我们又深入研究了镇银膏对体液免疫、细胞免疫和对脾脏<FONT face="Times New Roman">T</FONT>淋巴细胞增殖的影响,结果证明,镇银膏能显著增强<FONT face="Times New Roman">B</FONT>细胞抗体形成功能,降低小鼠腹腔巨噬细胞的吞噬功能,显著提高小鼠脾<FONT face="Times New Roman">T</FONT>淋巴细胞增殖活性。</FONT></P>
