SERUM-LIPID AND LIPOPROTEIN CONCENTRATIONS IN OBESE DOGS

Serum lipid and lipoprotein concentrations in 10 obese and 16 control dogs were examined. The serum triglyceride (TG) concentration in obese dogs was significantly higher than in control dogs. The serum concent rations of TG and phospholipid (PL) in beta lipoprotein and PL in pre- beta lipoprotein were significantly higher in obese dogs, while the se rum PL concentration in alpha, lipoprotein was significantly lower in obese animals. In the serum total cholesterol concentration in obese d ogs, a higher tendency for beta and pre-beta lipoproteins and lower te ndency for alpha, lipoprotein were observed. These abnormal lipoprotei n profiles were similar to those in diabetes mellitus in men and acute pancreatitis in dogs.
