７６４－３是从丹参中提取的有效单体，我们的工作曾表明，它具有抗炎症，抗纤维化等作用。本文观察７６４－３对老龄鼠ＰＭＮｓ功能（可能处于脆化状态）的影响，有助于为寻找抗衰老药物提供实验资料。实验用Ｗｉｓｔａｒ大鼠，雄性，鼠龄２２～２４个月，体重（５５０±４０?
764-3 is an effective monomer extracted from Salvia miltiorrhiza. Our work has shown that it has anti-inflammatory and anti-fibrotic effects. This article examines the effect of 764-3 on the function of PMNs in aged rats (which may be in an embrittled state) and helps to provide experimental data for the search for anti-aging drugs. Experimental Wistar rats, male, 22 to 24 months of age, weight (550 ± 40?
