Objectives: Dietary n-3 polyunsaturated fatty acids (PUFA) havepositive effects on the heart. In this present study, effects of pretreatment with fish oil (FO) and flaxseed oil (FLO) on rat's heart associated with the isoprenaline (ISO)-induced myocardial injury have been investigated.

Materials and Methods: Four groups (10male Wistar rats/each group), including control, ISO in which acute myocardial ischemiainrats induced by isoprenaline, FO + ISO in which rats pretreatment with fish oil orally for 4 weeks, and FLO + ISO in which rats pretreatment with fish oil and flaxseed oil orally for 4 weeks, were used. At the end of the study, histopathological examinations of cardiac tissues and serum activity of creatine kinase-MB (CK-MB) were assessed. Moreover, Mitochondria were isolated to examine mitochondrial swelling.

Results: Isoprenaline administration significantly increased the serum CK-MB activity compared to control group. Also, in more than 70% of rats in ISO group, severe muscular damage to the heart observed. In FO + ISO group, a remarkable decrease in the intensity of heart tissue destruction and in serum levels of CKMB in comparison with ISO group was observed. In FLO + ISO group, there was no a significant decrease in the serum level ofCKMB compared to ISO group.

Conclusion: Pretreatment with flaxseed oil significantly suppressed the intensity of heart tissue destruction as compared to the myocardial ischemic group. Fish oil and flaxseed oil led to decreasing CaCl2-induced swelling in the mitochondria. Our suggestion is that fish and flaxseed oils through inhibiting the MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) could lead toprotecting against ischemia/reperfusion injury.
