Effect of E. speciosa extract on oxidative stress parameters in rats subjected to Cold/restraint stress treatment

Treatment (mg/kg):	Catalase	SOD	GSH	MDA
	(umol H2O2/min/mg	(U/mg )	(mmol/g × 10-3	(mmol/g × 10-6 )
- Normal rats	5.13 + 0.90	8.26 + 1.02	6.99 + 0.12	3.08 + 0.59
- Negative control	3.07 + 0.70	5.53 + 0.20	6.26 + 0.20	4.98 + 0.82
- E. speciosa 100	7.34 + 1.20*	6.78 + 0.17	10.90 + 1.14*	1.20 + 0.49*
- E. speciosa 200	8.30 + 1.40*	9.99 + 1.30*	13.60 + 0.07*	2.10 + 0.63*
- Cimetidine 100	7.01 + 1.25*	6.31 + 0.31	7.57 + 1.12	1.90 + 0.52*

Statistically significant relative to the control, * (P<0.05); **(P<0.01); ***(P<0.001). SOD, superoxide dismutase; GSH, reduced glutathione; MDA, malondialdehyde. Each value is a mean from 6 rats ± SEM.
