| Abstract: | We undertook this study to determine the effects of a transplantable Leydig cell tumor on the major digestive glands of the host rats. It has been known that after bearing this tumor for only two weeks, the rats become anorexic and cathectic, develop hypercalcemia and osteolysis, and their peripheral bone marrow becomes hyperplastic. We now demonstrate that the parotid glands undergo marked degeneration including depletion of secretory product, apparent loss of acinar organization and the appearance of conjoined nuclei. The submandibular and sublingual glands and the pancreas are virtually unaffected. The liver undergoes fatty degeneration, the Kupffer cells become more prominent and more numerous, and the sinusoids sometimes contain small islets of hemopoietic tissue. |
