[Consequences in the rat of prolonged consumption of lactose or hydrolyzed lactose. 4. Composition of the liver].

Lots of 12 rats Wistar receive a well-balanced diet with 40 p. 100 of sucrose (control), or 40 p. 100 of lactose or hydrolyzed lactose in the form of whey or ultrafiltration permeate. After 270 days, the liver of experimental lots contains more thiamine (about +130 p. 100) and less total cholesterol (about -18 p. 100). The lactose feeding increases the liver riboflavine, more than the hydrolyzed lactose.
