[Effect of hyperoxia on RNA and protein concentration in cortical and spinal motor neurons and surrounding neuroglia].
Double-beam recording visible cytospectrophotometry showed that 30-minute convulsions due to 6 at. ga. hyperoxia result in a decrease in the RNA and protein content per cell in layer V neurons of the cerebral motor cortex and in the motoneurons of spinal cord anterior horn in albino rats. A decrease is also found in the glial cells, except for a spinal cord neuroglia. A decrease in the RNA content in the neurons as well as the protein content in the neurons and glia of the spinal cord is more pronounced than in similar structures of the cerebral motor cortex. The quantity of RNA and protein in the neurons and neuroglia of the cerebral cortex remins decreased for 24 h after hyperoxia cessation. In the spinal cord motoneurons the level of the RNA and protein becomes normal 3 h after hyperoxia, and 24 h later it exceeds the initial one.
