title: [Adenosine triphosphatase activity in the osmoregulatory organs of vertebrates].
abstract: Studies have been made on the activity of cation- and anion-stimulated ATPases, as well as succinic dehydrogenase in homogenates and subcellular fractions from osmoregulatory organs of marine (elasmobranch and teleost) and freshwater (teleost) fishes, amphibians, reptiles, birds and mammals. The activity of Na+, K+-ATPase was found to be rather similar in almost all osmoregulatory organs of the species investigated. The highest level of Cl-stimulated ATPase was found in microsomal fraction of the kidneys from birds and mammals. Succinic dehydrogenase activity is significantly higher in the renal tissue of mammals, both in total homogenates and in mitochondrial fraction.
