pOleoylanilide was administered orally to groups of rats according to different patterns. Subcellular fractionation of liver, lung and adipose tissue was then carried out in order to study the main enzyme activities involved in the lipogenesis. The observed findings indicate that adipose tissue and lung are the main target organs for the anilide, adipose tissue being involved in a general decrease of the enzyme activities, whereas transacylation reaction exhibits the most marked depletion of all the enzyme activities in the lung. The enzyme activities in liver were not markedly affected by this oral administration, although some data support the existence of a latent liver toxicity. These data suggest that oleoylanilide has the capacity to alter lipid metabolism of lung and adipose tissue to a considerable extent, whereas no major effect was produced in the liver. This different organ response could be related to the lymphatic gland via absorption of the substance./p
