中文摘要:
      目的 通过动物实验验证中药虎杖主要成分白藜芦醇对急性肺损伤大鼠的抗炎保护作用。方法 40 只SD大鼠随机分为空白对照组、肺损伤模型组、溶剂对照组和白藜芦醇治疗组,每组各10 只。气道内滴注细菌内毒素脂多糖(LPS)制备急性肺损伤模型,溶剂对照组腹腔注射单体溶解剂(脂肪乳),白藜芦醇治疗组腹腔注射白藜芦醇及溶解剂,分别在造模前24 h、造模时及造模后24 h 内进行腹腔内注射。造模后48 h 进行标本采集,肺组织进行病理染色检查并检测肺泡灌洗液(BALF)中性粒细胞比值、肿瘤坏死因子-α(TNF-α)及乳酸脱氢酶(LDH)的含量。结果 白藜芦醇治疗组的肺泡灌洗液中性粒细胞比值及TNF-α 数值为(68.432±20.623)、(92.644±11.322)ng/L,高于溶剂对照组的(87.023±4.032)、(106.654±4.606)ng/L,差异有统计学意义(P<0.05);两组肺泡灌洗液中LDH 数值比较,差异无统计学意义(P>0.05)。结论 白藜芦醇治疗组能显著减轻急性肺损伤引起的病理改变,白藜芦醇对急性肺损伤大鼠具有抗炎保护作用。
英文摘要:
      Objective To evaluate the protective efficacy of resveratrol,an effective component of polygonum cuspidatum,on acute lung injury through animal experiments.Methods A total of 40 SD rats were randomly divided into the blank group(n=10),the model group(n=10),the solvent control group(n=10)and the resveratrol treatment group(n=10).The acute lung injury model was established by intratracheal instillation of lipopolysaccharide(LPS).The solvent group was intraperitoneally injected with monomer dissolvent agent(fat emulsion),while the resveratrol treatment group was intraperitoneally injected with resveratrol and solubilizer.They were injected intraperitoneally 24 hours before,during and within 24 hours after the model was established.Samples were collected 48 hours after the model was established.Meanwhile,the lung tissues were examined by pathological staining,and the neutrophil ratio,tumor necrosis fac tor-α(TNF-α)and lactate dehydrogenase(LDH)contents in bronchoalveolar lavage fluid(BALF)were detected.Results The neutrophil ratio and TNF-α in BALF of resveratrol treatment group were(68.432±20.623),(92.644±11.322)ng/L,which were higher than those of(87.023±4.032),(106.654±4.606)ng/L in the solvent control group,with statistically significant differences(P<0.05).There was no statistically significant difference in LDH values between the two groups of BALF(P>0.05).Conclusion Resveratrol treatment group can significantly reduce pulmonary interstitial inflammatory cell infiltration,pulmonary interstitial edema,bronchoalveolar wall thickening and bronchoalveolar cavity destruction degree.Resveratrol has certain anti-inflammatory efficacy on rats with acute lung injury.
