Effect of hypoglycemia on free glutathione concentration in the brain regions of 14-day-old rats (a) and adult rats (b). Values are mean ± SD, n=6. There is a main effect of hypoglycemia on the glutathione concentrations at both postnatal ages (p<0.001 for each, ANOVA). *p<0.05, Control group vs. Hypoglycemia group (Bonferroni-adjusted unpaired t tests). Abbreviations: olf, olfactory bulb; ctx, cerebral cortex; hip, hippocampus; str, striatum; hyp, hypothalamus; mid, midbrain; crb, cerebellum; pns, pons; mob, medulla oblongata; and GSH, glutathione.
