title: The uptake of liposome-entrapped 125I-labelled poly(vinylpyrrolidone) by rat jejunum in vitro.
abstract: The uptake of free and liposome-entrapped 125I-labelled poly(vinylpyrrolidone) was measured in an intestinal sac preparation from adult rats. At an equal concentration of 125I-labelled poly(vinylpyrrolidone), the rate of uptake of the liposome-entrapped material was four times that of the free macromolecule.
