[Histochemical studies of several "K"-cell enzymes in guinea pig thyroid glands].
The thyroid gland of guinea pigs were studied morphologically. Histochemical methods were used for detection of lactate dehydrogenase, succinic dehydrogenase, cholinesterase, alkaline phosphatase and acid phosphatase. The distribution of "C"-cells in normal thyroid glands was proved to be uneven. In the center of the gland they were more numerous. For statistical investigations the method of silver impregnation of "C"-cells is more practicable, since they can not be obviously distinguished from acinar cells on the basis of glycerophosphate dehydrogenase only. The activity of cholinestarase in "C"-cells and in some other cells of folliculi epithelium is very high. A supposition is made that there exist two kinds of the follicular lining thyrocytes, having different histochemical properties and histogenesis as well.
