Influence of pinealectomy and long-term melatonin administration on GH-IGF-I axis function in male rats.
BACKGROUND: A relationship between circadian GH-IGF-I axis activity and pineal gland function in rats is not sufficiently elucidated, particularly in the aspect of melatonin (MEL) participation with relation to a possible mechanism of these dependencies.
OBJECTIVE: Influence of pinealectomy and long-term MEL admi.....
