摘　　要：本实验研究采用冷冻蚀刻技术定量分析了热暴露及游泳对ＳＤ大鼠小肠上皮细胞膜内微粒分布的影响。结果表明热暴露能显著影响小肠上皮细胞膜内微粒的分布特性，降低细胞膜和核膜膜内微粒的数量，游泳能加重其改变。停止受热后这些改变略有恢复，但停止受热后２４ｈ膜内微粒数量仍低于对照组水平。文中还讨论了这些改变的生物学意义。he effects of heat exposure and swimming on the distribution of theintramembranous particles (IMPs) at enteric epithelium of SD rats wereanalysed with freeze-etching technique in this study. The results showedthat heat exposure can markedly affect the distributional feature of IMPsof intestinal epithelium,and decrease the number of IMPs on the PF andEF faces of cell membrane and nuclear membrane,Swimming can exacerbateabove changes. These changes recovered partly after heat exposure,but thenumber of IMPs on the both fracture faces was still lower in the group VIIthan in the control group,The biological significance of above changes wasdiscussed.
