title: Thyroid C-cells in normal and goitrous gland: a histochemical study.
abstract: 16 cases of goiter were examined for C-cells and 4 cases with normal thyroid gland. C-cells identification was based on masked metachromasia. There was stated both in toxic, atoxic goitrous tissue two forms of C-cells. The first characterized by positive metachromatic reaction and weak argyrophinty, the second type of C-cells were orthochromatic and argyrophilic. Metachromatic C-cells characterized as a rule by high alpha glycero phosphate menadione reductase as well succinic dehydrogenase and cytochrome oxidase.
