Abstract:
:The effects of aspirin or 5-hydroxytryptamine (5-HT)-related drugs on the dental pain induced by electrical stimulation of tooth pulp afferent fibers were assessed in conscious monkeys. The electrical current required for producing jaw opening is referred to as the pain threshold. Both systemic (25 to 75 mg/kg, i.p.) or central (0.5 to 1.5 mg, third cerebral ventricle) administration of aspirin produced analgesia in monkeys. In addition, activation of central 5-HT receptors with central injection of either 5-HT or its precursor, 5-hydroxytryptophan, also produced analgesia. On the other hand, inhibition of central 5-HT receptors with central administration of either cyproheptadine (a blocking agent of 5-HT receptors), p-chlorophenylalanine (PCPA, an inhibitor of 5-HT synthesis) or 5,7-dihydroxytryptamine (5,7-DHT, a depletor of central 5-HT nerve fibers) produced an enhancement in pain sensitivity (or a decrease in pain threshold). Furthermore, the analgesia induced by aspirin was antagonized by pretreatment of monkeys with either cyproheptadine, PCPA, or 5,7-DHT. The results indicate that increases in the activity of central 5-HT neurons are associated with reduced dental pain and enhanced aspirin-induced analgesia, whereas decreases in the activity of those neurons correlate with dental hyperalgesia and diminished aspirin-induced analgesia in monkeys.
