Plasma lipid levels and heart lipoprotein lipase activity in mice under social stress. 1984

M Lavín-Palmieri, and D Sánchez-Serrano

The study was conducted in mice in order to elucidate whether psycho-social stimulation produced in an interconnecting box system was able to induce alterations in some circulating lipid fractions and in heart lipoprotein lipase (LPL) activity. Two groups of male mice were studied: A--a group isolated in glass jars from weaning to the age of 12-13 weeks and then transferred to the interconnecting box system with a reduced number of female mice, to 26 weeks of age; B--a second group isolated from weaning to 26 weeks of age, as an extremely opposite situation to group A. Control mice were kept in standard cages from weaning to the end of the experiment. Total cholesterol and triglycerides were determined in blood plasma, and heart LPL activity was determined in small portions of the ventricles. Cholesterol decreased significantly in group A (p less than 0.002) and in group B (p less than 0.05) vs. controls. No alterations were observed either in plasma triglycerides or in LPL activity in either of the two groups.

UI	MeSH Term	Description	Entries
D008055	Lipids	A generic term for fats and lipoids, the alcohol-ether-soluble constituents of protoplasm, which are insoluble in water. They comprise the fats, fatty oils, essential oils, waxes, phospholipids, glycolipids, sulfolipids, aminolipids, chromolipids (lipochromes), and fatty acids.

D008071	Lipoprotein Lipase	An enzyme of the hydrolase class that catalyzes the reaction of triacylglycerol and water to yield diacylglycerol and a fatty acid anion. The enzyme hydrolyzes triacylglycerols in chylomicrons, very-low-density lipoproteins, low-density lipoproteins, and diacylglycerols. It occurs on capillary endothelial surfaces, especially in mammary, muscle, and adipose tissue. Genetic deficiency of the enzyme causes familial hyperlipoproteinemia Type I.

D012934	Social Isolation	The separation of individuals or groups resulting in the lack of or minimizing of social contact and/or communication.
