Abstract:
:The effect of cage population density on plasma lipids and the development of atherosclerosis was examined in female C57BL/6 mice. Mice were housed at a density of one, two or five animals per cage and fed an atherogenic diet for 28 weeks. Subsequently, the animals were bled, sacrificed, the hearts removed and the extent of fatty lesion development in the aorta examined and quantified. As the population density increased, there was a statistically significant increase in total cholesterol levels, VLDL+LDL cholesterol levels, the VLDL+LDL/HDL ratio and lesion severity. These differences are due to the psychosocial stress associated with living within a confined space with high population density over an extended period of time.
