Introduction: 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.
Material and 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.
