Clinical and pathological study on the hyperbaric oxygenation treatment ofchronic hepatitis

AIM To study the effect and alteration of hepatic blood flow as well as ultrastructure of hepatic tissue inchronic cholestatic hepatitis after hypebaric oxygenation (HBO).METHODS Using the hepatic rheometer and Doppler B-mode ultrasound equipment, the contractive waveof hepatic blood flow and blood flow of portal vein were tested; the biochemistry, immunohistochemistryand ultrastructure of hepatic tissue were determined and served as the evaluating indexes.RESULTS After the HBO treatment, the contractive wave of hepatic blood-flow in 76% patients and bloodof right portal vein in 70% patients were increased, the improvement of serum ALT and BILI was 88.9%and 93.3% respectively. In addition, the swelling mitochondria, cholestasis of hepatic cells and capillariesreduced obviously; Kupffer's cells decreased. There was significant difference (t=2.85, P<0.05) beforeand after HBO treatment.CONCLUSION It is suggested that the HBO could increase the blood flow of portal vein and arteries,improve the hepatic function, cholestatsis and inflammation.     

Hepatic arterial blood flow in large hepatocellular carcinoma with or without portal vein thrombosis: assessment by transcutaneous duplex Doppler sonography

BACKGROUND: As liver cirrhosis progresses, the portal venous blood (PVBF) flow decreases, accompanied by an increase in hepatic arterial blood flow. Large hepatocellular carcinoma is a hypervascular tumour with a rapid growth, which seems to require an increase of the tumoral arterial blood flow. Furthermore, hepatocellular carcinoma is frequently associated with portal vein thrombosis, which subsequently impedes portal blood supply. METHODS: The purpose of our study was to estimate alterations in the hepatic arterial blood flow in large hepatocellular carcinomas occurring in liver cirrhosis, in comparison with liver cirrhosis and controls. Liver blood flow measurements were determined by duplex Doppler sonography in 47 patients with large hepatocellular carcinomas (13 with portal vein thrombosis and 34 without this thrombosis), 42 liver cirrhosis patients and 30 controls. The Doppler perfusion index was calculated as the ratio of hepatic arterial blood flow to total hepatic blood flow. RESULTS: The patients with liver cirrhosis had a significant increase of hepatic arterial blood flow as compared to controls (P < 0.001), accompanied by a significant reduction in PVBF (P < 0.005). As a result, the Doppler perfusion index was increased in patients with liver cirrhosis as compared to controls (P < 0.001). The hepatic arterial blood flow was increased in patients with hepatocellular carcinoma but without portal vein thrombosis as compared to the cirrhotic patients (P < 0.001), with a significant reduction of PVBF (P < 0.001). Hepatic arterial blood flow was also increased in patients with both hepatocellular carcinoma and portal vein thrombosis as compared to the patients without this thrombosis (P < 0.001). CONCLUSION: These results suggest that in large hepatocellular carcinomas there is a decreased PVBF, accompanied by an increased hepatic arterial blood flow. The hepatic arterial buffer response seems to be active in hepatocellular carcinomas and maintains liver perfusion to adequate levels.

Effects of posture change on the hemodynamics of the liver

BACKGROUND/AIMS: According to our experience, blood flow in the portal vein may alter according to body posture. It is reported that decreased portal venous flow immediately gives rise to significantly increased blood flow in the hepatic artery. To gain further insight into blood flow changes affected by posture, we examined blood flows in the portal vein, hepatic artery and hepatic vein at different postures. METHODOLOGY: Using a Doppler ultrasound system, the hemodynamics of the portal vein, right hepatic artery, and hepatic vein were examined in 35 patients at supine and left decubitus positions. RESULTS: Portal vein blood flow volumes were significantly lower in the left decubitus position than in the supine. In the right hepatic artery, the left decubitus position gave significantly higher blood flow velocity values than the supine. CONCLUSIONS: Our results indicated that upon change of posture from the supine to left decubitus position, portal vein flow velocity was reduced and hepatic artery flow velocity increased. Changes in portal and hepatic arterial flows by changing posture may be explained by decreased portal flow as a direct result of changed posture, leading to increased hepatic arterial flow to maintain total hepatic blood inflow.     

The effects of arterialisation of the portal stump on liver function and hepatic haemodynamics in cirrhotic rats with a portacaval shunt

Liver blood flow (xenon-133 clearance method) and wedged hepatic venous pressure were studied in cirrhotic rats immediately after and 3 weeks following portacaval shunting (PCS), PCS and arterialisation of the portal stump with the left gastric artery (PCS-ART) or sham operation. Liver weight and function were compared 3 weeks after operation. Liver blood flow and wedged hepatic venous pressure were significantly reduced immediately after and 3 weeks following PCS. PCS-ART maintained liver blood flow and wedged hepatic venous pressure within the pre-operative range and prevented the liver atrophy and deterioration in liver function observed in rats with PCS. The results suggest that arterialisation of the portal vein with an artery which does not significantly increase sinusoidal pressure may be of benefit in preventing the early undersirable sequelae of PCS in man.     

Clinicopathological study in treatment of chronic hepatitis with hyperbaricoxygenation

AIM To probe into the feasibility and theoretic basis for the treatment of chronic hepatitis with hyperbaricoxygenation (HBO).METHODS Sixty cases of chronic hepatitis were randomly distributed into an experimental group (n=30)and a control group (n =30). The experimental group was treated with HBO for 6 courses. The controlgroup was treated with commonly used drugs in clinic for 60 days. The function and blood stream graph ofliver were examined and the liver biopsies were made before and after treatment. The routine paraffin slidesof liver tissue were cut, stained with HE, and observed under optical microscope. The ultrathin slides fromparaformaldehyde and glutaraldehyde fixed liver tissue were cut, stained with lead citrate, and observedunder transmission electric microscope. The HBsAg and HBcAg in the experimental group were detected bythe ABC immunohistochemical method before and after treatment.RESULTS In the experimental group the ALT, SB, γ-GT, AKP, IgG and IgM in blood (P< 0.05) and thedegeneration and necrosis of hepatocytes (P<0.05) were remarkably decreased, the mean contractive waveof blood stream in the liver (P<0.05) and the blood stream in the right ramus of janitrix (P<0.05) weresignificantly increased, and the swelling of mitochondria, the increased lysosomes, the generation of Kupffer's cells, the infiltration of lymphocytes in portal area and the capillary generation were remarkably alleviated(P<0.05), but the fibrosis and fat-storing cells did not reduce (P>0.05) in the liver, and the expression ofHBsAg and HBcAg in the liver was not lowered (P<0.05) after the treatment with HBO.CONCLUSION The treatment with HBO for chronic hepatitis was effective and recommendable.     

Effects of Cimetidine and Ranitidine on Splanchnic Hemodynamics in Patients with Chronic Liver Disease

Effects of two histamine H2 receptor antagonists, cimetidine and ranitidine, on systemic and splanchnic hemodynamics were studied in patients with chronic liver disease by simultaneous catheterization of the portal vein and the right hepatic vein and measurement of portal venous flow using the ultrasound doppler system or cineangiography. Neither infusion of 200 mg of cimetidine nor 50 mg of ranitidine reduced cardiac output, portal venous pressure, the gradient between wedged hepatic venous pressure and free hepatic venous pressure, hepatic blood flow, and portal venous flow. It is unlikely that histamine is an important modulator of flow via the H2 receptor.
