[Transference of cyclic monomeric acids into the milk of female rats eating thermopolymerised linseed oil].

Six month old female Wistar rats were fed a commercial diet until littering. Then they received a diet containing 10 p. 100 by weight of thermopolymerized linseed oil at 275 degrees C for 12 hours under nitrogen atmosphere. No mortality has been found among young rats during lactation but body growth is slower. In rats sacrificed at the age of 14 days stomach content (milk) and liver were analyzed for lipids. In milk and liver fatty acids respectively 2,7 and 3,0 p. 100 cyclic monomers (18 C) were detected. Consequently, the present study shows that these abnormal compounds formed during hearing of the oil are transmitted to the youngs before weaning through mother's milk.
