The effect of elastase on chickens with endogenous hyperlipidemia
Biochemical Medicine and Metabolic Biology
|February 1, 1987
Summary
Elastase treatment reduced atherosclerosis in chickens by lowering calcium and lipid accumulation in aortic tissue. This suggests elastase may be a therapeutic agent for preventing cardiovascular disease.
Area of Science:
- Cardiovascular Science
- Biochemistry
- Pharmacology
Background:
- Elastase exhibits activities potentially protective against atherosclerosis.
- Previous reports suggest a role for elastase in cardiovascular health.
Purpose of the Study:
- To investigate the antiatherosclerotic effects of elastase in hyperlipidemic chickens.
- To determine the impact of elastase on calcium and lipid accumulation in aortic tissue.
Main Methods:
- Treatment of hyperlipidemic chickens with varying doses of elastase.
- Assessment of calcium and lipid content in aortic tissue.
- Monitoring of plasma cholesterol levels.
Main Results:
- Elastase demonstrated a clear antiatherosclerotic effect in hyperlipidemic chickens.
- Reduced accumulation of calcium and lipids in aortic tissue was observed.
- A potential plasma cholesterol-lowering effect was noted.
- Lipid removal from the intima, particularly lipid bound to elastin, was a significant finding at 600 U elastase.
- Reductions in tissue calcium required a higher dose of 1800 U elastase.
Conclusions:
- Elastase possesses significant antiatherosclerotic properties.
- The enzyme aids in the removal of lipids from the arterial intima.
- Elastase may serve as a therapeutic strategy for managing atherosclerosis and hyperlipidemia.
