Effect of removal of the Harderian glands on pineal melatonin concentrations in the Syrian hamster
Abstract
Peak melatonin levels which are normally present in male Syrian hamsters at 8 h after the onset of darkness in animals maintained under a light:dark cycle of 14:10, were significantly decreased following the removal of the Harderian glands.
