RESUMEN
The mitochondrial ATPase activity of heart and gastrocnemic muscles of thyroidectomized and control rats was determined. Some rats were fed an n-6 polyunsaturated fatty acids (PUFA)-rich diet A and others were fed an n-3PUFA-rich diet B, during 30 days. The heart mitochondrial ATPase activity of rats fed diet A was higher than of rats fed diet B in both thyroidectomized (p < 0.01) and control (p < 0.05) groups. The thyroidectomy induced an increase of heart mitochondrial ATPase activity in both dietary groups (p < 0.01). The thyroidectomy also induced an increase in gastrocnemic mitochondrial ATPase activity in diet B group, but it induced a decrease in ATPase activity in diet A group. The data suggest that the dietary lipids and the absence of thyroid gland induce changes in mitochondrial ATPase activity in heart and gastrocnemic muscles, confirming the same observations previously y described for the effect of thyroidectomy and diet in rat liver and brain (9)
