Table 2.

Blood level of GSSG/GSH ratio, reduced (GSH) and oxidized (GSSG) glutathione, mRNA expression of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px) and glutathione-S-transferase (GST) in peripheral blood mononuclear cells from 19 women at baseline and 30 days after surgical menopause (Menopause). Statistical differences were assessed using Student's t-test for repeated measures.

Blood GSH (nmol/L)	54.69±12.28	39.28±10.42⁎
Blood GSSG (nmol/L)	4.98±1.32	7.40±2.63⁎
SOD mRNA expression (%)	100±24.48	64.20±29.56⁎⁎
CAT mRNA expression (%)	100±36.72	89.31±31.55
