title: Fluidity of the rat liver microsomal membrane: increase at birth.
abstract: The lipid apparent microviscosity of the rat liver microsomal membrane on the first day after birth was found to be half of that observed on the last day of fetal life. This remarkable perinatal fluidization of the membrane resulted from a marked increase in the molar ratio of phospholipids to cholesterol.
