The Relationship Between Prostacyclin Activity and Pressure in the Portal Vein
George Hamilton, Rose Chow Fung Phing, Ronald A. Hutton, Paresh Dandona, Kenneth E. F. Hobbs – 1 March 1982 – The effect of portal hypertension (induced by partial ligation) on the ability of the portal vein wall to produce prostacyclin (PGI2) was studied in rats over a period of 6 weeks. PGI2‐like activity measured by bioassay was shown to be significantly increased in portal vein segments during established hypertension when compared to control groups. As a collateral circulation developed with consequent fall in portal venous pressure, PGI2‐like activity decreased.
