曾报道,紫草的醚提物能加速棉球诱导的肉芽组织增生。本次对右旋紫草素和紫草素促进大鼠肉芽组织增生的作用进行了组织学研究。 材料和方法:①棉球诱导肉芽组织增生试验:右旋紫草素和紫草素分别溶于1％吐温80。雄性Wistar大鼠体重约为250g,随机分组。在乙醚麻醉下,背部皮肤消毒后做一切口,皮下植入一重约(20±1.0)mg的消毒棉球(其中右旋紫草素组及紫
It has been reported that the ethereal extract of Lithospermum can accelerate the proliferation of granulation tissue induced by cotton balls. The histological study on the effect of dexenotrifluoride and shikonin on the proliferation of rat granulation tissue was performed. Materials and Methods: 1 Cotton ball induced granulation tissue proliferation test: Dexperimentin and Shikonin were dissolved in 1% Tween 80, respectively. Male Wistar rats weighing approximately 250 g were randomized. Under ether anesthesia, an incision was made after disinfecting the dorsal skin and a subcutaneous (20±1.0) mg sterilized cotton ball was implanted subcutaneously (in which the Shikonin group and purple
