[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.
