[Rheologic changes of blood in portal hypertension].

The role of hemorheologic disorders in the pathogenesis of portal hypertension in shown. Rheologic disorders are characteristic of both intrahepatic and extrahepatic forms of portal hypertension. It was found that the rate of hemolysis, disorders of the lipid composition and conformation of red cell proteins is reduced in cirrhosis of the liver complicated by portal hypertension.

[Comparative characteristics of the lipid composition of lipoproteins of the blood plasma and ascitic fluid in liver cirrhosis].

Comparison of phospholipid content in different fractions of lipoproteins of the ascitic fluid and blood plasma showed selective accumulation of high density lipoproteins (HDLP) in the ascitic fluid. The ascitic fluid HDLP differed from blood plasma HDLP in a larger fraction of triglycerides and cholesterol oleate. No significant difference was revealed in the lipoprotein (LP) low density lipid spectrum in the two fluids.
