[Electron-microscope study of ribonucleoprotein particles in the cerebral cortex neurons during the posthypoxia...

As demonstrate the experiments performed in rats, during the postanoxic period in the cerebral cortex neurons, the content of nuclear and cytoplasmic ribonucleoproteids changes essentially. The most labile and highly sensitive components of the protein-synthesizing system in the neuron are the perichromatin fibrillae. Then the perichromatin and interchromatin granules disappear. An increased formation of the perichromatin fibrillae in the nucleus precedes the activation of the reparative processes.
