Long-term effects of an inotropic phosphodiesterase inhibitor (ICI 153,110) on the rat salivary gland, harderian gland, and intestinal mucosa.

Abstract

The inotropic vasodilator, ICI 153,110, a phosphodiesterase inhibitor intended for the treatment of congestive heart failure, was administered to Alderley Park Wistar-derived rats for periods of up to 182 days. Treatment produced hypertrophy of salivary glands, hyperplasia of intestinal mucosa, and dacryoadenitis of the harderian gland. As the functions of these glandular tissues can be modified by factors which alter cyclic nucleotide metabolism, it is postulated that the glandular alterations produced by ICI 153,110 occurred as a result of phosphodiesterase inhibition.
