Skeletal marrow volume in dog

¹ Department of Oral Biology, School of Dentistry, State University of New York at Buffalo, Buffalo, New York

A method for determining dog marrow volume was described. The skeletal bone was considered to be of three parts: trabecular and cortical bones and marrow, all containing water and nonfatty organic material. Fat and mineral fractions were considered to be exclusively of the marrow and bones, respectively. The marrow water and nonfatty organic fraction (each obtained by taking the difference in its amounts found in the trabecular plus cortical and skeletal bones) and all of the fat equals the marrow volume. The vertebrae were the major contributors to the total marrow, containing half of the over-all marrow water and nonfatty organic fractions. The long bones contained most of the fat. A large amount of fat was also found in the vertebrae, skull, and the pelvic girdle. The marrow content in individual skeletal bones ranged from 23.9% for the mandibles to 65.9% for the sternum. About 49% of the skeleton was marrow.

Key Words: marrow water • marrow fat • skeletal bone volume • skeletal contents • distribution of marrow in skeleton
