Title: [Ultrastructural characteristics of the neocortex during rehabilitation from the sequelae of long-term protein-energy deficiency]. Author: Medvedev DI, Babichenko II, Eremina IZ, Kravtsova AI. Journal: Biull Eksp Biol Med; 1985 Dec; 100(12):751-4. PubMed ID: 3935189. Abstract: Electron microscopy of mouse neocortex was carried out during rehabilitation following long-term protein-caloric deficiency. Food rehabilitation led to partial recovery of brain ultrastructure, however, a high neuronal level of secondary lysosoms and lipofuscin bodies was preserved, with the changes in the spine apparatus and synaptic contacts persisting in neuropile. Carnitine addition to food during rehabilitation increased the number of free ribosomes in cortical neurons. A substantial development of granular endoplasmic reticulum was observed. A greater number of spine apparatus cisterns was detected, however, like in conventional rehabilitation, the width of synaptic clefts and postsynaptic densities remained narrower than in control mice.[Abstract] [Full Text] [Related] [New Search]
