热暴露大鼠红细胞的形态学

Morphological Observation on the Ery throcytes in Rats during Heat Exposure

实验对热暴露大鼠外周血红细胞的主要形态改变进行了光镜和电镜观察。结果发现,受热后口形纤细胞、靶状红细胞、网织红细胞总数、Ⅱ型和Ⅲ型网织红细胞明显增多。受热晚期,网织红细胞等效量明显减少,晚幼红细胞等明显增多,有时还伴有其核的明显形态异常。

The predominant morphological changes of erythrocytes in the peripheral blood of rats during heat exposure were observed with light andelectron microscope.Our results showed that the number of the stomatocytes,the totalnumber of reticulocytes,and type reticulocytes increased obviously at theearly stage of heat exposure.The number of the target cells clearly increased at the midde stageof the heat exposure.The number of reticulocytes decreased obviouslywith increase in erythroblast at the late stage of the heat exposure andsome nuclear changes were occasionally observed at this stage.
