本文利用水浴致热模型,通过形态、功能及一些生化指标研究了大鼠小肠(6cm回肠段)局部加温(43℃,30min)损伤后实质及间质的结构、功能损伤与修复的动态特点,旨在了解小肠实质和间质微血管热损伤与修复的规律及二者的相互关系。 实验结果表明:小肠热敏感性较高,其对热损伤反应快、损伤重,损伤后单位面积肠湿重、单位面积肠上皮细胞计数(包括绒毛表面及隐窝伤皮)、横截面隐窝计数均在热损伤后2h或6h显著降低达最低值,分别为
In this paper, the structure and function of damaged and repaired parenchyma and interstitium after injury by local warming (43 ℃, 30min) of small intestine (6cm ileum) in rats were studied by using the model of water heating induced by heat. , Aimed at understanding the law of intestine parenchyma and interstitial microvascular heat injury and repair and the relationship between the two. The results showed that the heat sensitivity of the small intestine was high, which had a rapid response to heat injury, heavy damage, intestinal wet weight per unit area, intestinal epithelial cell count per unit area (including villous surface and crypts), cross-section crypts The counts were significantly lower at 2h or 6h after heat injury, reaching the lowest values, respectively
