Abstract

Sulphur metabolism was studied in thymuses of 8 young dogs stressed by peripheral irradiation. Autoradiographic studies revealed a significantly heavier uptake of 35S in the medulla, rich in reticular cells, than in the cortex (t = 9.556, P = 0.001). In epithelial cysts in the thymus the uptake of 35S was so dense that it appeared as black areas. Possibility of sulphur-containing secretion was discussed.

Keywords: thymus, reticular cells, epithelial cysts, 35S, irradiation
