[Changes in the vessels of the kidneys in rats on a choline- and protein-deficient diet]

Prolonged (from 4 to 10 months) keeping of rats on a cholinoprotein- and protein-deficient diets produces an associated moderate damage to the wall on renal blood vessels and glomerulopathy. There take place dystrophic alterations in the elastic skeleton of the interlobular arteries in the form of elasticity loss and impairment of the tinctorial properties on the internal elastic membrane combined with vacuolization of the smooth muscle cells of the media.
