Abstract
RNA synthesis in neuronal nucleoli of the rat cerebral cortex was studied by electron microscopic autoradiography in rats before and 1, 12 h, 3 and 6 days after burn injury. It was ascertained that the rate of RNA synthesis begins increasing rapidly after burn injury (1 h) and reaches high level after 12 h. The decrease in the rate of RNA synthesis proceeds more slowly than the increase. This rate does not return to normal even by the close of day 6 following injury.
摘要
通过电子显微镜放射自显影术，研究了大鼠烧伤前及烧伤后1小时、12小时、3天和6天大脑皮质神经元核仁中的RNA合成情况。结果确定，烧伤后（1小时）RNA合成速率开始迅速增加，12小时后达到高水平。RNA合成速率的下降比增加过程更为缓慢。即使在受伤后第6天结束时，该速率仍未恢复正常。
