  • Title: [Ultrastructural and biochemical changes in the muscle tissue of Notothenia nudifrons L. during prolonged cold preservation].
    Author: Lebskaia TK, Dolgikh NG, Dubnitskaia GM, Pakhomova KI, Khobotilova LD.
    Journal: Arkh Anat Gistol Embriol; 1985 Feb; 88(2):64-71. PubMed ID: 3994529.
    Abstract:
    During initial stages freezing and conservation of Notothenia nudifrons L. muscle tissue are accompanied with nonspecific changes in the intracellular membranous system of fibers, in their lipid and protein composition. Certain connections between development of destructive changes in mitochondrial membranes, sarcoplasmic reticulum, T-system and intensity of accumulation of free fatty acids and products of peroxide oxydation of tissue lipids are revealed. Manifestation of hydrolitic enzymes activity coinsides, in time, with formation of autophage vacuoles. Transformation of the latter into residual bodies is in accord with a decreased enzymatic activity. A supposition is made concerning the mechanism of the muscle tissue destruction in the process of a prolonged conservation in cold.
