Modulation of luteinizing hormone release and catecholamine activity by opiates in the female rat.

abstract：BACKGROUND/AIMS:Tryptophan is the precursor of serotonin and niacin (vitamin B3). The latter is critical for normal cellular metabolism. Tryptophan and niacin can be deficient in patients with serotonin-producing neuroendocrine tumors (NETs). Niacin deficiency may lead to severe symptoms including pellagra. In patients...
