Abstract:
Indomethacin increased the secretion by low concentrations of isoproterenol (IPR, 30-100 nM) and decreased the secretion by a high concentration of IPR (1 microM). Indomethacin also had opposite effects on the secretions induced by low and high concentrations of norepinephrine (NE). PGE2 did not affect the secretions induced by IPR and NE, but it reversed the stimulatory and inhibitory effects of indomethacin. These findings suggest that PG has a role in modulating the amylase secretory response of the rat parotid gland.
