摘 要:目的研究三七总皂苷(PNS)对博来霉素诱导的大鼠急性弥漫性肺泡损伤(ADAD)的保护作用。方法将24只SD大鼠随机分为3组,A组静脉注射0.9%氯化钠溶液1.5 ml/kg作为对照;B组和C组静脉注射博来霉素诱导ADAD,而后B组注射0.9%氯化钠溶液,C组静脉注射PNS,均连续注射3 d。3 d后测定3组动脉血浆肿瘤坏死因子α(TNF-α)水平、支气管肺泡灌洗液(BALF)中巨噬细胞(PAM)和中性粒细胞(PMN)总数、BALF中蛋白质和肺组织中超氧化物歧化酶(SOD)水平;计算肺组织含水率;光学显微镜下观察肺组织形态学改变。结果 B组大鼠TNF-α水平、PMN总数、蛋白质及含水率高于C组,C组高于A组(P<0.01);B组SOD水平低于C组,C组低于A组(P<0.05)。3组PAM总数比较,差异无统计学意义(P>0.05)。光学显微镜下观察到B组肺组织间质水肿、细胞浸润明显,相比C组肺组织以上改变明显减轻。结论 PNS对博来霉素诱导的大鼠ADAD具有减轻和保护作用。Objective To study the protective effect of PNS on SD rats with acute diffuse alveolar damage( ADAD) induced by Bleomycin. Methods 24 SD rats were randomly divided into 3 groups. Group A was given intravenous injection with 0. 9% sodium chloride solution,1. 5 ml / kg; groups B and C were given intravenous injection with Bleomycin,then group B was given intravenous injection with 0. 9% sodium chloride solution,group C was given intravenous injection with PNS,all continuous injected for 3 d. The TNF- α,PAM and PMN in BALF,SOD among 3 groups were detected. Results The TNF- α, PMN,protein and moisture content in group B were higher than those of group C,group C was higher than those of group A( P〈0. 01); SOD in group B was lower than that of group C,group C was lower than that of group A( P〈0. 05). There was no significant difference of PAM among 3 groups( P〉 0. 05). Group B pulmonary interstitial edema and cell infiltration were obviously,compared to group C was reduced. Conclusion PNS has protective effect on acute diffuse alveolar damage induced by Bleomycin in SD rats.
