[Malate dehydrogenase and glutamate dehydrogenase activity modification in livers of rats exposed to a double stress (dry heat - fasting). I].

We have studied MDH and GLDH behaviour in liver homogenized of rats exposed to double stress (dry heat and starvation) for 24 hours respectively. Both enzyme showed a statistically significant activity increase, either after 24 and 72 hours. Such an increase is affected mainly by starvation. This behaviour reflects the metabolic needs of organism, related to increased energetic requirements.

[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.

[Modification of malate dehydrogenase and glutamate dehydrogenase in hearts of rats exposed to a double stress (dry heat - fasting). III].

MDH and GLDH activity modifications have been studied in heart homogenized of rats exposed to double stress (dry heat and starvation). MDH activity shows statistically significant variations only after 72 hours. This induces to suspect a decrease of energetic metabolism due to a probable substratum lack. GLDH activity shows a statistically significant decrease after 24 hours, and this decrease increases after 72 hours. This behaviour could be explained by an acclimatization reaction of such an amount to delete the hunger effect on protein catabolism.
