WebApr 1, 2013 · Photomutagenicity (or photogenotoxicity) in a strict sense refers to the ability of UV light to induce mutations or chromosomal aberrations after direct absorption by the DNA molecule. This property has long been known. The mechanisms have been investigated in fine detail, and the relevance to human health is well established. WebOptimal conditions were determined to obtain maximal induction of MN, followed by demonstrating feasibility and reproducibility of the method. The results of the present study indicate that the in vivo rat skin photomicronucleus test may be a promising tool for detection of photoclastogenicity. dallachulish lodge
