Valproic acid (VPA) is an effective
drug which has been widely preferred for the primary medication of epilepsy.
Although this drug is used as antiepileptic drug, its deleterious effect on
organs and tissues and in turn its elevator effect on oxidative stress sourced
species is inevitable. Lens is one of the most affected tissues because of VPA
induced oxidative stress. Alpha lipoic acid (ALA) is a potent antioxidant that
inhibits the effects of free radicals. It inhibits oxidative stress by
suppressing reactive oxygen species. The aim of this study was to investigate
the protective effects of alpha lipoic acid against valproic acid-induced lens
damage in rats. In our study, rats were divided into four groups: the control
group, the ALA-treated group (50 mg / kg), the VPA-treated group (0.5 g / kg),
the VPA + ALA group (at the same dose and duration). The rats were given ALA prior to
administration of VPA. ALA and VPA were administered to rats for 15 days. On
day 16 rats were sacrificed and lens samples were taken. In the VPA treated
lens homogenates, glutathione levels and glutathione-S-transferase activities
decreased. Lipid peroxidation levels, superoxide dismutase, glutathione
peroxidase, glutathione reductase, aldose reductase, sorbitol dehydrogenase
activities and protein carbonyl levels increased. These values were reversed
upon administration of ALA. According to the results of our study, it was
concluded that alpha lipoic acid had a protective effect against valproic
acid-induced lens damage.
