Iii. The Chemical Composition of the Fat Emboli in the Post‐alimentary Dog

Abstract

Abstract. The composition of the pulmonary fat emboli, plasma and bone marrow triglycerides were compared in the traumatized dog in the post‐alimentary state. The animals had been fed triglycerides with a fatty acid pattern different from both post‐absorptive plasma and bone marrow triglycerides. This fat intake caused the appearance of chylomicrons with a triglyceride fatty acid pattern similar to that of the ingested fat. These alterations in the plasma triglycerides were not reflected in the emboli and bone marrow triglyceride composition. The results therefore indicate that there was no significant contribution of the chylomicrons to the fat emboli.

V. The Chemical Composition of the Fat Emboli in Dogs With Extirpated Liver and Intestines

“…I n the cwiitrol lobe the mean number remaining in the lung lobes was on an average 40, 10 and 10 per cent, respectively, of that of the nonpcrfused lobe. I n the animals without fractures (tc' Cl-F C2) only a few emboli were observed, but the general impression c\as that the number of emboli was somewhat higher than in the animals without fractures in the previous studies in these series (6,9).…”

“…I n t'he previous studies in these series it was shown that fat emboli have a composition similar to that of adipose tissue triglycerides, indicating that the source of the emboli fat in traumatized dogs (femoral fractures) is the dipose tissue (5,6,8). However, this does not IiecessariIy mean that the emboli are mechanically 1iberat)ed from the traumatized fat.…”
