Figure 6: The effect of ACR and SN pretreatment on serum CK-MB level. Vehicle-control group received normal saline +0.5% w/v methylcellulose, orally for 3 weeks. ACR was given (7.5 mg/kg, orally) for 3 weeks. SN was injected 7 days before ACR and daily thereafter throughout the study (3 weeks). Vit E (100 IU/Kg, three times per week) plus ACR were administrated for 3 weeks. SN alone at dose (100 mg/kg, intraperitoneally) was treated for 4 weeks.
