[Effects of a duodenal infusion of rapeseed oil in cows in full lactation. 2. Lipogenic and lipolytic activities of the perirenal adipose tissue].
Oil infusion tended to decrease acetate incorporation into lipids by perirenal adipose tissue in vitro, without changing glucose incorporation into glyceride-glycerol. Lipolysis (glycerol release) tended to increase when suboptimal concentrations (4 x 10(-7)M) of isoproterenol were used. Free fatty acid release (basal and isoproterenol stimulated) was significantly increased. Clonidine (an alpha-2 agonist) decreased the isoproterenol (4 x 10(-7)M) stimulated release of glycerol and free fatty acid, but only in oil-infused cows.
