[Effects of a definite stress on the enzyme activities in blood plasma in mice (author's transl)].

The present study was designed to analyze the effects of a short term stress on the quantitative levels of alkaline phosphatase (AP), creatine phosphokinase (CK), aldolase (ALD), lactate dehydrogenase (LDH), and lactate dehydrogenase-1-isoenzyme (LDH 1) during 24 h after stress. For all the enzymes studied higher values for the activity were found due to stress in comparison to the activity level before the stress. The period during the 24 h after stress to reach maximum activity depends on the enzyme and in part on the sex of the animal.
