Abstract
-
PURPOSE: Adriarnycin induced cardiomyopathy is irreversible and may procede to clinical
congestive heart failure. Recently, it has been suggested that adriamycin may exert
cardiomyopathy due to inhibition of transport across mitochondrial membranes rnediated by
the carnitine palmitoyltransferase system(CPT I). The effect of adriamycin on fatty acid
metabolisrn according to cumulative dose was not clarified. The purpose of this study was
to ascertain the acute effect of adriamycin on lipid and fatty acid metabolism accoring to
cumulative dose.
METHODS
Sprague-Dawley rats were divided into two groups. The first group was control.
The second group was given intraperitoneal injection with adriamycin(5mg/kg) twice a week
for 2 weeks. Serum lipid (total cholesterol, triglyceride, HDL cholesterol, LDL cholesterol)
and fatty acid levels were analyzed on the first day, 8th day, and 11th day after injection
of adriamycin.
RESULTS
Total cholesterol, triglyceride, and LDL cholesterol were significantly higher in
adriamycin group compared to the control group. HDL cholesterol was similar in both groups.
Total cholesterol and LDL choleterol level significantly increased over the adriamycin dose.
Total fatty acid levels were significantly higher after injection of adriamycin. Long chain
fatty acids such as palmitic acid, linoleic acicl and oleic acid levels were significantly
elevated in the adriamycin group.
CONCLUSION
Serum lipid and fatty acid levels increased significantly after injection of
adriamycin.
