Total phospholipids (PL) as well as the content of various phospholipid classes and their fatty acid composition have been investigated in the brain of mesopelagic and abyssal marine teleosts. These species were compared to shallow water ones. The brain of deep sea fishes was found to be very poor in PL as compared to the brain of mesopelagic ans surface(More)
Sodium reabsorption is low in coldblooded animals (the lamprey Lampetra fluviatilis, red salmon Oncorhynchus nerka, carp Cyprinus carpio, frog Rana temporaria, tortoise Agryonemis horsfieldi) being much higher in warmblooded ones (chicken, pigeon, rat). High level of Na transport in warmblooded animals is paralleled by high activity of succinate(More)
Brain lipids of 4 species of sturgeons-Acipenser güldenstädti, A. stellatus, A. ruthenus and Huso huso-have been investigated. In whole brain homogenates the content of the basic phospholipid families, their fatty acid composition as well as the content of glycosphingolipids-gangliosides, cerebrosides and sulfatides were studied. The quantitative relations(More)
