[Fructose-1,6-diphosphate aldolase and ketose-1-phosphate aldolase isoenzyme spectra in the kidneys normally and in uranyl acetate poisoning].

Activities of both aldolases were distinctly decreased in acute kidney insufficiency, caused by administration of uranyl acetate. The decrease in the activity of fructose-1,6-diphosptate aldolase was more distinct which led to alteration in ratio between fructose -1,6-diphosphate and ketose-1-phosphate aldolases. The isozyme spectra of the enzymes were also altered. Isozymes of fructose-1,6-diphosphate aldolase AB2 and of ketose-1-phosphate aldolase form 22 possessed the same electrophoretic mobility but their relative activity was increased 2-3-fold under conditions of the acute kidney insufficiency. At the same time, the more electrophoretically mobile isozymes were not detected.

[Activity of glycolysis key enzymes in subcellular structures of normal kidneys and under acute renal insufficiency].

The activity of key glycolysis enzymes (hexokinase, glucose-6-phosphatase, phosphofructokinase, fructose-diphosphatase and ketose-1-phosphate aldolase) in the kidney tissue and its subcellular structures was studied in normal rats and in rats with experimental acute renal insufficiency. It is established that considerable biochemical changes in the kidney tissues affecting all the elements of cellular structures occur under acute lesion of the kidneys. The activity of the enzymes under study under acute renal insufficiency lowers to a greater extent in those subcellular structures of the kidneys where they are mainly localized. The arising disturbances in permeability of the kidneys cellular membranes intensify the release of the mentioned enzymes to blood serum and urine, that in its turn disturbs the coordination of certain glycolysis stages.
