Experimental Study on Effects of Ultraviolet Exposure on Hydroxyproline Content of Moue’s Liver and Kidney

Objective To study the effect of chronic whole body ultraviolet exposures to organ hydroxyproline content.Methods To determinate hydroxyproline content of liver and kidney after chronic whole body ultraviolet exposures of hairless mice.Results Liver hydroxyproline content elevated and butylated hydroxytoluene or nicotinamide showed no protection.No significant effect on kidney hydroxyproline but butylated hydroxytoluene and acetone cause slight increase of kidney hydroxyproline.Conclusion The effects on collagen metablism of internal organs by chronic UV exposure and some sun2burn protectants should not be ignored and needed further study.
