BACKGROUND As numerous papers have presented many disturbances of blood lipid composition and changes in lipolytic enzyme activity, it was considered appropriate to investigate the postheparin lipolytic activity in serum of psoriatic males. The course of serum lipolytic process provoked by intravenous application of heparin was observed by measuring the concentration of the major substrates and products: triglycerides (TG), free fatty acids (FFA) and glycerol (G) before intravenous bolus of heparin 10 units per 1 kg b.w. and after 30 minutes. METHODS The study group consisted of 30 psoriatic males with mean age 29.7 +/- 9.6 and mean BMI 24.2 +/- 3.3 and was compared with 35 healthy males with corresponding mean age and mean BMI. The release of glycerol and FFA and the reduction of TG concentrations following intravenous heparin were observed. RESULTS Psoriatic sera demonstrated higher concentrations of triglycerides, glycerol and free fatty acids before and after the lipolysis compared with the controls. The course of postheparin lipolysis in psoriatic males seems to be changed as compared with the control group.

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. (Grant & Hackh's Chemical Dictionary, 5th ed)	Lipid
D008066	Lipolysis	The metabolic process of breaking down LIPIDS to release FREE FATTY ACIDS, the major oxidative fuel for the body. Lipolysis may involve dietary lipids in the DIGESTIVE TRACT, circulating lipids in the BLOOD, and stored lipids in the ADIPOSE TISSUE or the LIVER. A number of enzymes are involved in such lipid hydrolysis, such as LIPASE and LIPOPROTEIN LIPASE from various tissues.	Lipolyses

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D011565	Psoriasis	A common genetically determined, chronic, inflammatory skin disease characterized by rounded erythematous, dry, scaling patches. The lesions have a predilection for nails, scalp, genitalia, extensor surfaces, and the lumbosacral region. Accelerated epidermopoiesis is considered to be the fundamental pathologic feature in psoriasis.

D006493	Heparin	A highly acidic mucopolysaccharide formed of equal parts of sulfated D-glucosamine and D-glucuronic acid with sulfaminic bridges. The molecular weight ranges from six to twenty thousand. Heparin occurs in and is obtained from liver, lung, mast cells, etc., of vertebrates. Its function is unknown, but it is used to prevent blood clotting in vivo and vitro, in the form of many different salts.
