  • Title: [Morphologic, biochemical and functional properties of the mitochondria of the rabbit gastric mucosa].
    Author: Pokrovskiĭ AA, Gapparov MM, Doronin PP, Levachev MM, Mal'tsev GIu.
    Journal: Tsitologiia; 1975 Feb; 17(2):175-80. PubMed ID: 167483.
    Abstract:
    Purified fractions of the rabbit gastric mucosa and liver mitochondria were isolated. Electrone microscopy and functional studies of mitochondria showed the most intact mitochondria of gastric mucosa to be localized in gradient fractions of p=1.16-1.18, and those of the liver in fractions with p=1.19-1.20. The gastric mitochondria differed from the liver mitochondria by specific localization in oxyntic cells, abundance of crists, small matrix volume, presence of high respiratory control at lesser values of pH, high respiratory activity, great amount of cytochromes of electron transport chain in inner mitochondria membrane, two-fold excess of cytochroma a in relation to b and c, absence of b5 and by presence of great amount of phosphathydilaethanolamine and unsaturated fatty acids.
