Pattern of myelin proteins in moderate hypoxia

Myelin proteins isolated from the brain of Wistar rats subjected to moderate hypoxia (7% of oxygen in a respiration gaseous mixture) for 30 min were investigated. Among the various protein fractions Wolfgram protein happened to be most markedly affected, demonstrating considerably lowered percentages in all experimental groups, starting from 24 h after hypoxia. Our findings compared with those obtained in other experimental conditions lead to the conclusion that changes in the myelin protein pattern are characteristic for particular morbid processes evoked by various pathogenic factors. The demyelination is concomitant with severe loss of basic proteins, whereas myelin lesions of other types are connected with changes in protein of higher molecular mass.
