Abstract： 目的探讨高压氧(HBO)对急性下肢缺血再灌注大鼠血小板膜糖蛋白CD31、CD61和CD62p表达的影响.方法大鼠随机分为下肢缺血再灌注组(再灌注组)、下肢缺血再灌注+HBO处理组(HBO组)、假手术组.夹闭大鼠腹主动脉,建立急性下肢缺血再灌注大鼠模型.观察急性下肢缺血再灌注大鼠经HBO治疗后大鼠的血小板膜糖蛋白CD31、CD61和CD62p表达的变化.结果再灌注组大鼠血小板膜糖蛋白CD31和CD62p表达均高于假手术组,差异具有显著性(P＜0.05),而HBO组CD31和CD62p表达均低于再灌注组,差异具有显著性(P＜0.05).假手术组、再灌注组和HBO组3组之间CD61表达差异无显著性.结论急性下肢缺血再灌注可以导致大鼠血小板膜糖蛋白CD31和CD62p的表达量增加,而早期HBO治疗可有效抑制这些血小板膜糖蛋白的表达,可能有助于减轻缺血再灌注损伤.
