洋金花治疗银屑病有效部位的药理作用研究(Ⅱ)——对免疫功能、上皮细胞有丝分裂及皮肤角化的影响

Studies on Pharmacological Actions of the Active Parts in Flos Daturae for Psoriasis(Ⅱ)——on Immune Function,Epithelial Cell Mitosis and Skin Keratosis

目的:研究洋金花治疗银屑病有效部位对免疫功能、皮肤角化及上皮细胞有丝分裂的影响,进一步阐明其药理作用,为临床应用和开发新药提供依据。方法:通过对小鼠溶血素含量的影响及对植物血凝素(PHA)刺激的小鼠淋巴细胞转化的影响,研究其对免疫功能的作用;研究其对小鼠阴道上皮细胞有丝分裂活性和对小鼠尾背部皮肤鳞片角化的影响。结果:洋金花治疗银屑病有效部位对正常小鼠溶血素含量有降低的趋势,但无明显差异性;对PHA刺激的小鼠淋巴细胞转化无明显影响。可显著抑制小鼠阴道上皮细胞的有丝分裂;显著提高小鼠尾鳞片颗粒层形成数,有明显的促进皮肤角化的作用。结论:洋金花治疗银屑病有效部位对实验动物的体液免疫和细胞免疫无明显影响;具有明显抑制小鼠阴道上皮细胞有丝分裂和促进小鼠尾背部皮肤鳞片角化的作用。

Objective:To study the effect of active parts in Datura metel L.(APD) for psoriasis on immune function,skin keratinized and epithelial cells mitosis,to clarify the mechanism for clinical applications and developing new drug.Methods:APD s effects on immune function were measured by the content of mice s hemolysin and lymphocyte transformation stimulated by phytohemagglutinin(PHA).The influence on the activity of vaginal epithelial mitotic cells and the effect on skin scales keratosis at the back of tail were...
