- In this paper we have studied the influence of a well-established rat model of periodontitis on resting and adrenergic-stimulated mucin secretion from rat submandibular glands. The selective β1-receptor subtype agonist, dobutamine, induced mucin secretion while the selective β2-, α1- and α2-agonists, soterenol, phenylephrine and clonidine, respectively, did not. In rats subjected to ligature-induced periodontitis mucin release, under unstimulated conditions (basal values), was significantly increased. This increment was abolished in the presence of propranolol and atenolol. Isoproterenol, concentration-dependent, increased mucin release in control and in ligature-induced periodontitis rats. Maximal effect of isoproterenol was decreased in rats with ligature while EC50 was increased. Neither, the inhibition of NOS by l-NMMA nor the inhibition of COX by indomethacin could revert the effect of ligature on mucin release under unstimulated and isoproterenol-stimulated conditions. The inhibition of adenylyl cyclase by SQ 22536 resulted in a right shift of isoproterenol concentration-response curves in both groups, control and with ligature and returned basal values of rats with ligature to control ones. β-Receptor population was decreased in submandibular gland membranes from rats with ligature without changes in affinity. Potencies of the β-receptor antagonists in the competition studies were similar in both groups under study, control and with ligature. We conclude that in rats subjected to ligature-induced periodontitis unstimulated mucin secretion is increased. The increment seems to be due to an activation of the sympathetic system since it is inhibited by the β-adrenoceptors antagonists and by the inhibition of the adenylyl cyclase. We can speculate that inflammatory mediators from the experimental periodontitis could be involved in the mechanism underlying the activation of the sympathetic system.
