Basal values of plasma enzyme activities and myocardial mitochondrial antioxidant parameters in rats

	LDH	AST	CPK	GSH	GR	GPX	ICDH	MDA
	U/L			nmol/mg protein	mU/mg protein			pmol/mg protein
Mean (SD) (n = 6)	129.8 (10.8)	31.2 (2.68)	158.1 (20.4)	4.3 (0.25)	2.4 (0.24)	2.8 (0.26)	308.8 (23.0)	90.5 (5.39)

Plasma lactate dedydrogenase (LDH), aspartate aminotransferase (AST) and creatine phosphokinase (CPK) activities, as well as myocardial mitochondrial reduced glutathione (GSH) level and glutathione reductase (GR), Se-glutathione peroxidase (GPX), and isocitrate dehydrogenase (ICDH) activities, and malodialdehyde (MDA) level were measured in rats immediately after an intraperitoneal injection of saline.
