Summary
The histochemical alkaline phosphatase reaction in thyroid vascular endothelium was estimated spectrophotometrically and stereologically. Thus two main characteristics of the reaction were obtained: 1. the average enzyme activity, reflecting the level of transport processes in the capillary-thyrocyte system; 2. the relative volume of functioning vessels. An index of thyroid vascularity is proposed that is equal to the product of these two characteristics. The changes of the primary characteristics as well as of the vascularity index, caused by experimental hypo- and hyperplasia of the gland, are discussed.
