Bertram I. Cohen, Erwin H. Mosbach, Charles K. McSherry, Richard J. Stenger, Syoji Kuroki, Beverly Rzigalinski – 1 September 1986 – The effects of a standard rodent chow were compared with those of a semisynthetic diet of known composition (with and without added cholesterol) in the prairie dog model of cholesterol cholelithiasis.
