The protective effect of vitamin U on pentylenetetrazole-induced brain damage in rats

Pentylenetetrazole (PTZ) is preferred for experimental epilepsy induction. PTZ damages brain and other organs by elevating oxidative substances. Vitamin U (Vit U) is sulfur derivative substance that proved to be an excellent antioxidant. The current study was intended to determine the protective role of Vit U on PTZ-induced brain damage. Male Sprague-Dawley rats were separated into four groups. The Control group (Group I), was given saline for 7 days intraperitoneally (i.p); Vit U (Group II) was given as 50 mg/kg/day for 7 days by gavage; PTZ was injected into animals (Group III) at a single dose of 60 mg/kg, by i.p; PTZ + Vit U group (Group IV) was administered PTZ and Vit U in same dose and time as aforementioned. After the experiment was terminated, brain tissues were taken for the preparation of homogenates. In the PTZ group, glutathione and lipid peroxidation levels, alkaline phosphatase, myeloperoxidase, xanthine oxidase, acetylcholine esterase, antioxidant enzyme activities, total oxidant status, oxidative stress index, reactive oxygen species, and nitric oxide levels were increased. However, total antioxidant capacity was decreased in the PTZ group. Vit U ameliorated these effects in the PTZ-induced brain damage. Consequently, we can suggest that Vit U protected brain tissue via its antioxidant feature against PTZ kindling epilepsy.

Automated summary

The study aimed to investigate the protective role of Vit U against PTZ-induced brain damage. The results showed that Vit U can alleviate oxidative stress caused by PTZ and protect brain tissue.
