[Total lactate dehydrogenase content and its isoenzymes in a human platelet subpopulation].

The morphological and functional variability of the platelets is on the way of the study. The morphological platelet transformations corresponding to functional attitudes, need of energetic pattern given by the content, in platelets, of enzymatic patrimony. The results show that the lactic-dehydrogenase and isoenzymes, content in the three studied platelet subpopulations, is different. These significant data, probably show that the platelet subpopulations have a different content in total LDH while show no modification in LDH isoenzymes as show in various functional and energetic different specific point in time.
