Abstract

The modulation of fetal insulin secretion by prostaglandins was studied with the aid of the prostaglandin synthesis inhibitors indomethacin and sodium salicylate in 10 chronically catheterized fetal lambs. Glucose-induced fetal insulin secretion was inhibited within 60 minutes by preinjection of either indomethacin or sodium salicylate in the fetal lambs. In the sodium salicylate experiments a significant (p < 0.01) dose-related response (degree of insulin suppression) was noted between doses of 100 to 350 mg/kg of fetal weight. In a selected group of sodium salicylate injections prostaglandin levels were found to fall to 58% of control by 2 hours after injection. Five neonatal lambs exposed to a similar regimen were noted to have an exaggerated insulin response to glucose infusion when compared to fetal lambs. However, indomethacin or sodium salicylate pretreatment resulted in no suppression of glucose-induced insulin release. This finding may be of importance in explaining the observation of an increased incidence of fetal growth retardation after long-term exposure to salicylates in humans and in animal models.
