[Modification of malate dehydrogenase and glutamate dehydrogenase in kidneys of rats exposed to a double stress (dry heat - fasting). II].
MDH and GLDH activity changes have been studied in kidney homogenized of rats exposed to double stress (dry heat and starvation) for 24 and 72 hours respectively. MDH behaviour activity decrease after 24 hours and increase to basic values after 72 hours leads to suspect the primer of a defence mechanism that precedes to face up increased metabolic needs. GLDH activity shows a constant decrease after 24 hours and after 72 hours; this was explained as a premature acclimatization reaction.
