为了探讨腐植酸钠对大鼠皮肤创伤愈合的作用,本试验建立了大鼠皮肤切创模型,以不同浓度的腐植酸钠(0.5%、1%、2%)作用于伤口,分别于术后3天、6天、9天、14天、21天时间点观测创面愈合率和平均愈合时间,H E常规染色观察新生肉芽组织及形态学改变。结果表明,腐植酸钠各剂量组的创伤平均愈合时间为(13.7±0.65) In order to investigate the effect of sodium humate on wound healing in rats, a rat skin wound healing model was established in this experiment. Sodium humate (0.5%, 1%, 2%) was applied to the wounds at different time points The wound healing rate and average healing time were observed at 3, 6, 9, 14 and 21 days. HE staining was used to observe the changes of granulation tissue and morphology. The results showed that the average wound healing time of each sodium humate dose group was (13.7 ± 0.65)
