Serum cortisol, growth hormone (GH), and luteinizing hormone (LH) were measured in 6 controls and in 9 normal subjects following oral administration of 500 mg of Levodopa (L-Dopa). Serum cortisol levels decreased similarly in both the treated and the control group over a 3 h teste period. Serum GH levels increased dramatically, whereas LH levels showed a small but significant decrease in 7 of 9 subjects. These alterations occurred during the first 2 h following L-Dopa administration. GH and LH levels did not change significantly in the controls. These results suggest that L-Dopa exerts a selective stimulatory and inhibitory influence on the secretion of anterior pituitary hormones in man.
These data suggest a potential risk of developing DIC after extended use of the Cavitron Ultrasonic Surgical Aspirator for cytoreduction of ovarian cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
