摘要
补体激活引起的中性粒细胞(PMN)聚集在微血管内形成栓子阻滞血流,井释放溶酶体酶损伤组织,是发生体克和多器官衰竭的一个重要原因。我们用青藤碱预处理大鼠PMN,发现可抑制酵母多糖活化血浆(ZAP)引起的PMN激活时的形态学改变和溶酶体酶释放。细胞仍呈球形,皱折不增多,无伪足形成、聚集较少。PMN上清液内弹性蛋白酶和N—乙酰—β—D葡萄糖苷酶(NAG)含量增加较少。提示青藤碱在体克和器官损害中可能有保护作用。
Complement activation induces polymorphonucleal neutrophilic leukocyte (PMN) aggregation in circulation causing microvascular occlusion. The activated PMNs release lysosome enzymes which damage the tissue. It might take an important part in shock and multiple organ failure. We pre-treated rat PMNs with sinomeuine, which was extracted and purified from the stem of Sinomeuium acufum Rehd et Wils. It was found to inhibit the morphological changes and lysosome enzymes release in PMNs activated with zymosanactivated plasma. With administration of sinomeuine PMNs remained a spherical shape, no apparent ruffling or cytoplasmic projection and less aggregation. Elastase and Nacetyl-β-D-glucosaminidase content in PMNs supernatant increased less.
