Acomparative study of Lipomatosis in the Salivary Glands of Mammals with special reference to the Echindna.

Abstract

The occurrence, site, and morphology of lipomatic changes in the salivary glands of the pig, sheep, cattle, horse, dog, goat, rhesus monkey, guinea pig, bandicoot, rabbit, and the echidna were investigated, special attention being given to the glands of the echidna. The areal, tubular, acinar, marginal, central, interlobular, peritubular, paratrabecular, and capsular accumulations were described. It was concluded that lipomatic changes in the salivary glands are of two distinctly different types, one being the formation of fatty cells from the cells of the connective tissue and the other being the partial or complete transformation of the glandular cells into fatty cells.
