Research Abstract |
Salivary glands of rats fed a liquid diet for 3 weeks were investigated microscopically to clarify the effects of soft food on salivary glands. Parotid glands of experimental rats became atrophic after liquid diet feeding, and cell shrinkage, cell death, and reduction of speed of cell-cycle were identified in the atrophic parotid glands. However, such atrophic alterations were not observed in submandibular and sublingual glands following liquid diet feeding. These observations suggest that it depends on the kind of salivary glands whether liquid diet feeding induces atrophy to the salivary glands.
