Uma aproximação ao uso de 8-metoxipsoraleno na toxicidade fotoquímica quando activado por UVB banda estreita (311nm) no Saccharomyces cerevisiae

A Saccharomyces cerevisiae model was used to evaluate the photochemical toxicity of 8-methoxypsoralen expressed as percentage of growth inhibition using tow different concentrations, 0.4mM and 0.05mM, and UVB narrow-band (311nm) for the photo activation. The preliminary results suggest that the concentration of 8-MOP play a role on the photochemical toxicity, but not, with the concentrations used, on the chemical toxicity.
