Phospholipids in artificially induced muscular dystrophy of calves

Abstract

1. Phospholipds were studied in the heart muscles, skeletal muscles and livers of seven Ayrshire calves which received vitamin E-free maize oil (in filled milk) with and without supplementary α-tocopherol from 1 week old for 17 d. The calves that were not given vitamin E developed muscular dystrophy.2. Decreased amounts of cardiolipin and increased amounts of sphingomyelin were found in the skeletal muscles of vitamin E-deficient calves. There was a significant decrease of phosphatidyl choline in the livers of vitamin E-deficient calves.3. The decrease in cardiolipin concentration confirmed the electron-microscopical picture (reported elsewhere) of preferential destruction of mitochondria in muscular dystrophy of calves.

Seasonal variations in lipid composition of spanish wild rabbit (Oryctolagus cuniculus) meat

“…The identity and amount of the other phospholipids are in agreement with the results of Kostetskii et al (1977), although they found neither lysophosphatidylcholine nor lysophosphatidylethanolamine; instead they detected phosphatidylinositol, which we did not find. Similar phospholipid classes have been identified in ovine (Dawson 1960), porcine (Wood andLister 1973) and bovine species (Evarts and Oksanen 1973) and in poultry (Hay et a1 1973).…”
