The nucleic acid content of the nuclear fraction of cerebral hemispheres was studied 1, 3, 7, 20 and 90 days after unilateral removal of superior cervical ganglion. The results obtained indicate that the content of nuclear RNA is significantly reduced in the desympathized side 1 day after removal of the ganglion. Seven days after sympathectomy the content of RNA increases, reaching control levels. Beginning from the 20th day it decreases and remains at a low level for 90 days. This decrease is observed on both sides of the brain. The content of nuclear DNA is significantly reduced seven days following removal of superior cervical ganglion. The possible mechanisms of the alterations observed are discussed in connection with changes in correlation of nucleic acids with nuclear proteins.
在单侧切除颈上神经节后1天、3天、7天、20天和90天，研究了大脑半球核部分的核酸含量。所得结果表明，切除神经节后1天，去交感神经一侧的核RNA含量显著降低。交感神经切除术后7天，RNA含量增加，达到对照水平。从第20天开始下降，并在90天内维持在低水平。大脑两侧均观察到这种下降。切除颈上神经节后7天，核DNA含量显著降低。结合核酸与核蛋白相关性的变化，讨论了观察到的改变的可能机制。
