The possible neurobehavioral protective effects of natural antioxidant against phototoxicity attenuation of antimicrobial quinolone group in rats.

The fluoroquinolones absorb light in the 320 to 330  nm ultraviolet A (UV-A) wavelength and produce reactive oxygen species (ROS) such as superoxide anion, hydroxyl radical, and hydrogen peroxide; thus, the photodynamic generation of ROS may be the basis of phototoxicity of quinolones in human beings and animals. This study aimed to evaluate the damaging effects of UV-A radiation at different periods of exposure on rats' brains administered with ciprofloxacin. Ciprofloxacin administration in UV-A exposed animals exaggerated the brain-oxidative stress biomarkers and decreased the locomotor activity.
