title: Effect of prostaglandins in vivo on enzymes involved in thyroid carbohydrate metabolism.
abstract: Treatment of adult guinea pigs with prostaglandins produces changes in the levels of enzymes involved in carbohydrate metabolism of the thyroid gland. A decrease in glucose-6-phosphate dehydrogenase activity is observed with a concomitant increase in 6-phosphogluconic dehydrogenase; the glycolytic enzymes appear unaffected by the same treatment. The results indicate that prostaglandins do not have the biochemical effects obtained with thyrotropin and cAMP administration, showing that these compounds play an antagonistic role in comparison with the above mentioned stimulating agents.
