Ocular kinetics of 8-methoxypsoralen. An experimental study with pigmented and albino rabbits without UVA-stimulation.

Tritiated 8-methoxypsoralen (8-MOP), with radioactivity in the ring system, was injected into both pigmented rabbits and albino rabbits; at 0.5, 1, 2, 4, 6, and 24 h after 8-MOP injection the animals' plasma and ocular radioactivities were determined by liquid scintillation counting. The experiment was done without photostimulation but in incomplete darkness.
