The behaviour of cyclic-3',5'-AMP phosphodiesterase has been studied in the presence of psoralen, 8-methoxy-psoralen (8-MOP), 4,5',8-trimethylpsoralen (TMP) (usually used in PUVA therapy), 4,6,4'-trimethylangelicin (TMA) and khellin recently proposed for the same therapeutical use. TMP and TMA exhibit a significant inhibitory effect on cyclic AMP phosphodiesterase; a light inhibition is produced by khellin at rather high concentration.
The methods of Marzulli-Ruggles and Draize were used in an assessment of eye irritation on the part of three children's shampoos. Two products proved irritant with the Marzulli-Ruggles method. The most aggressive product was designated VAS-2-36/A. Better tolerance was observed in albino rabbits when the Draize method was used, though even here some ocular alterations were noted. Once again, VAS-2-36/A was the most irritant substance.
