Response of glandular organs to experimental macroglossia.

Response of glandular organs to tongue enlargement was studied in 16 outbred male rats; each of them received injections of hydrophobic polyacrylamide gel (0.05 ml) in midline of the tongue. Changes in the studied glandular organs of external secretion (salivary glands) and internal secretion (thyroid and adrenal glands) were morphometrically detected.
