title: The effect of environmental lighting on porphyrin hepatic metabolism in the rat.
abstract: It has been shown that light may stimulate hepatic porphyria in the rat. This is evidently due to a neuro-endocrine pathway involving retina, nerve pathways in the brain and including the sympathetic chain, the pineal gland and the gonads. This light effect in porphyria appears to be via a circadian rhythm in the liver.
