摘要: 目的: 观察川芎嗪对博莱霉素所致鼠肺纤维化组织钙含量及钙调素活性的影响, 探讨川芎嗪防治肺纤维化的机制。方法: 将 32 只 SD 大鼠一次性气管内注入博莱霉素 A 5 制备肺纤维化模型, 随机分为2 组:模型组(n=16) 及川芎嗪组(n=16), 分析测定各组给药后 d 14、d 28 肺组织钙含量及钙调素活性, 并与正常对照组(n=8) 比较。 结果: 模型组肺组织钙含量及钙调素活性较正常组明显增高(P<0.01), 川芎嗪组各期钙含量及钙调素活性均低于模型组(P<0.05), 同时组织病理学显示肺泡炎及肺纤维化程度均较模型组明显减轻。 结论: 川芎嗪防治鼠肺纤维化的机制可能与降低肺组织钙含量及钙调素活性有关。

Abstract: AIM: To observe the effect of ligustrazine on the calcium contents and calmodulin activity of lung tissue in rats of the bleomycin-induced pulmonary fibro-sis.METHODS: Thirty-two SD rats were replicated into pulmonary fibrosis models by intratracheal injection of bleomycin A 5 in one lump and were divided into two groups randomly, untreated model group (n=16) and ligustrazine group(n=16).The calcium contents and calmodulin activity of the lung of the rats of each group were assayed on d 14, d 28 after the injection and com-pared with control group (n=8).RESULTS: The cal-cium contents and calmodulin activity of model group were obviously higher than control group (P<0.01), and ligustrazine groupwere lower than those of model group at all pases (P<0.05).The degree of alveolitis and fibro-sis of the lung studied by histopathology was lower than that in the model group.CONCLUSION: The mecha-nism of the protective effect of ligustrazine on bleomycin-induced pulmonary fibrosis may be related to decrease the calcium contrents and calmodulin activity.
