Effect of JP4-039 on sulfite-induced decrease in glutathione peroxidase (GPx), A, B, glutathione reductase (GR), C, D, glutathione transferase (GST), E, F, and glucose-6-phosphate dehydrogenase (G6PDH), G, H, activities in rat striatum 30 minutes after sulfite injection (2 μmol). Pretreatment with JP4-039 at the doses of 3.5 and 5.0 μg/g, A, C, E, G, or 5.0 and 5.0 μg/g, B, D, F, H, was performed via intraperitoneal injection 24 and 2 hours prior to sulfite administration. Values are means ± SD for four to seven independent experiments (animals) per group. *P < .05, **P < .01, compared to rats receiving NaCl (2 μmol) (control group); #P < .05, compared to rats receiving sulfite (sulfite group) (Duncan multiple range test)
