Effect of naloxone on the nocturnal rise of rat pineal melatonin content

Rats exposed to 14 light: 10 h dark photoperiods were given naloxone hydrochloride (10 mg/kg) s.c. 2 h before and 5 h after the lights were turned off. A smaller noctúrnal pineal melatonin peak, as well as a slower decrease from peak values were observed in naloxone-treated rats. Naloxone (up to 10-...
