  1. The present studies aimed to find the responses of neurons and glias in the target and other brain areas of the linear accelerator - irradiated rats. in the first experiment, time - dependent neurons changes in the brain after hemispheric irradiation at an single - fraction maximal dose of 20 gy were observed by investigating the expression of an immediate early gene, fos protein. the results shown : compared with that of the un - radiated rats, the expression of fos protein in the irradiated brain decreased distinctly 24 hours and 1 week after irradiation

    首先,利用即刻早期基因fos的表達,做了同一照射劑量( 20gy )照射大鼠半腦后不同存活期間( 1d , 7d , 14d , 2ld , 28d )大鼠全腦神經元動態變化的觀察,發現:受照射后1d 、 7d大鼠腦內各部位fos蛋白表達均明顯減少,隨著時間的延長,其fos免疫反應性細胞數量逐漸增加,照射后28d ,延髓、第四軍醫大學碩士學位論文腦橋內hs免疫陽性細胞數量恢復並超過正常對照組水平,但中腦、間腦及端腦內未恢復到正常對照組水平。
