[Changes in renal enzyme activity in rats with experimental hypertension].

The study was carried out on rats of the Wistar strain with experiments hypertension by the method of Selye, modified by Kolarova. These authors examined the activity of the enzymes of protein metabolism (GOT, GPT, AP), of glycolysis (ALD, LDH, alpha-HBDH) and of the citric cycle (MDH) in the left and right kidney at various intervals after modeling the process (3th, 15th, 30th and 90th day). The activity of the enzymes of the glycolytic chain and the cycle of Krebs in the left kidney was lowered at all stages of the experiment. Transaminase activity diminished progressively. Such a dynamics revealed the activity of adenosine phosphate as well. The activity of all examined enzymes of the right kidney showed phase changes-after initial elevation on the third day there was a lowering at the later stages of the experiment. The altered activity off the left kidney was connected with the disturbed vascularization with subsequent metabolic changes. The changes in the enzymic activity in the right kidney were assumed as a consequence of the occurred adaptive hyperfunction.
