| Abstract: | The aim of this study was to evaluate the effect of 2,5-dihydroxybenzoic acid, a salicylate derived from Acetyl salicylic acid (ASA) and vitamin A (vit A) on Na+, K+ ATPase enzyme and GSH levels in brain of rats exposed to hyperoxia (Hyp) as oxidant protocol. Rats were treated as follow: group I (control), group II (Hyp), group III (Hyp, ASA), group IV (vit A), group V (Hyp, vit A), group VI (Hyp, vit A, ASA). Vit A was given 5 days before and during Hyp, aspirin at the end of Hyp. Na+,K+ ATPase and total ATPase activity was significantly increased in group V. Levels of GSH showed a significant increase in group III, besides, levels of 2,5-dihydroxybenzoic acid as salicylate in plasma were significantly increased in group II. These results elucidate differences in the biochemical response of animal towards intake of various types of antioxidant substances, with increased GSH and salicylate in hyperoxia. |
