^(60)Coγ射线照射后大鼠胸腺淋巴细胞对主动脉血管内皮细胞的粘附

ADHESION OF THYMUS LYMPHOCYTES TO AORTIC ENDOTHELIAL CELLS IN RVTS IRRADIATED WITH ^(60)Co-γ-RAYS

本文用体视学方法对^(60)Coγ线照射Wistar大鼠后粘附于主动脉血管内皮细胞上的胸腺淋巴细胞的数量变化进行了初步观察。实验大鼠分为受0Gy(对照组)和2.0、8.0Gy剂量照射的三组,在照射后6小时处死,制备淋巴细胞粘附主动脉内壁的标本,做主动脉段横截面的切片,H-E染色,在光镜下观察组织切片,计数粘附在血管内皮细胞上的淋巴细胞数。结果表明,受^(60)Coγ线照射后胸腺淋巴细胞粘附于主动脉血管内皮细胞上的数量有显著下降;胸腺和主动脉同时受照射后,粘附在血管内皮细胞上的淋巴细胞数量较单纯照射胸腺时为高。

Adhesion of thymus lymphocytes to aortic endothelial cells in Wistar rats irradiated with ^(60)Co-γ-rays was preliminarily investigatedwith a stereological method. The results of experiments suggest that thenumber of lymphocytes of thymus which adhered to aortic nedothelia1 cellssignificantly (p<0 .01) decreased after irradiation at doses of 2 and 8Gy.However,when both thymus and aorta were irradiated,there were morelymphocytes adhering to endothelial cells than that when only thymus wasirradiated.
