[Inhibitory effect of angiotensin blockade on hepatic fibrosis in common bile duct-ligated rats].

Backgrounds And Aims: Angiotensin receptors are found on hepatic stellate cells, which participate in hepatic fibrosis. Therefore, it is presumed that angiotensin has a role in hepatic fibrosis. The aim of this study was to evaluate the effects of angiotensin blockade on inhibition of hepatic fibrosis in cirrhotic rat model.

[Interequipment variability of Doppler ultrasonographic indices in patients with liver cirrhosis].

Backgrounds/aims: Doppler ultrasongraphy is used to evaluate hemodynamic alternations in patients with liver cirrhosis. Purpose of this study was to determine the interequipment variability of Doppler indices in portal and splenic vein in cirrhosis.

Methods: Blood velocity, diameter, flow and congestive index in portal and splenic vein were measured by Doppler ultrasonography in 30 patients with cirrhosis using two different machines.
