Recovery of atrophic parotid glands in rats fed a liquid diet by switching to a pellet diet.

Objective: In this study, we aimed to clarify how parotid glands, made atrophic by a liquid diet, recover after diet change.

Design: Seven-week-old male Wistar rats were fed a pellet (control group) or a liquid diet (experimental group) for the first 14 days. Thereafter, all animals were fed a pellet diet for up to 14 days (days 0-14).
