Histochemical and enzymatic study of the thyroid nodule.

Twenty-four cases of uninodular and polynodular thyreopathy subjected to partial or total thyroidectomy in 1980--1981 were studied. At the same time with the general morphological study, the activity of the following cellular enzymes in the thyroidian tissue were assayed: lactic dehydrogenase (LDH), glutamic oxalacetate transaminase (GOT), glutamic pyruvate transaminase (CPT) and creatine phosphokinase (CPK). Correlations between the morphophysiopathology of the thyroid nodule and its enzymatic activity have been made.
