PLLA-induced augmentation is most likely based on capsule formation orchestrating macrophages, (myo-)fibroblasts, and collagen type I and III fibres. We observed considerably slower degradation of PLLA particles than described previously. Thus PLLA partic
乳酸是葡萄糖或糖原经过糖酵解无氧代谢过程的最终产物。长期以来，乳酸被广泛认为是导致运动能力下降和运动疲劳的代谢废物。然而，近年研究发现，乳酸在机体中具有重要作用：1）乳酸作为能量底物和糖异生前体，不是导致代谢性酸中毒的原因，反而起到缓冲作用；2）乳酸穿梭作用于靶向部位，发挥细胞间信号传导的信使作用；3）乳酸既是脑的重要能源物质，又可以介导运动改善认知和记忆的过程。
Objective To investigate the efficacy of poly (L-lactic acid) application in the rejuvenation of hands, and to analyzethe safety of its application. Methods two subjects with aging problems of the hands were given subcutaneous injections of poly-L-lactic
