ABSTRACT
The fatty acid (FA) contents of heart and gatrocnemic muscle mitochondrial lipids of thyroidecromized and control (sham-operated) were analyzed. Animals were fed either an n-6 polyunsaturated (PUFA)-rich diet A or an n- PUFA-rich diet B during 30 days. It was observed alteraions in the composition of FA of those cell organelles caused by the absence of the thyroid gland. Some of these alterations were dependent of the type of used diet. Thyroidecromy caused an increase of P?S ratio in heart and gastrocnemic muscle but only for animals fed diet B. Thyroidectomy caused an increase of n-6/n-3 ratio in heart of rats fed diet A and in gastrocnemic muscle of rats fed diet B and it caused a decrease of n-6/n-3 ratio of heart of rats fed diet A and in gastrocnemic muscle of rats fed diet B. The absence of thyroid gland in some way may interfer in the FA metabolism and in the rate of FA incorporation into endogeneous lipids but in a different process dependent of type of tissue and of used lipid diet
