Hemodynamic and morphological changes in the stomach of portal hypertensive rats.
To determine hemodynamic and morphological changes in the stomach of portal hypertensive rats, male WKA rats were given CCl4 subcutaneously in order to induce liver cirrhosis. The portal venous pressure of cirrhotic rats was significantly higher (17.7 cm H2O) than that of controls (10.5 cm H2O). Mucosal blood flow of the stomach in the portal hypertensive rat was increased (+ 46%) compared with...
متن کاملAdrenal Dysfunction in Portal Hypertensive Rats with Acute Hemorrhage
Nitric oxide (NO) participates in shock and poorer portal hypotensive effect to vasoconstrictors in portal hypertension with hemorrhage, the so-called splanchnic hyposensitivity. Relative adrenal insufficiency accompanies hemorrhagic shock and is found in liver disease, the 'hepatoadrenal syndrome', but the relevant interactions remain unsettled. Portal hypertensive rats were induced by partial...
متن کاملDisordered central cardiovascular regulation in portal hypertensive and cirrhotic rats.
Portal hypertension due to either prehepatic portal hypertension or cirrhosis is associated with cardiovascular derangement. We aimed to delineate regulatory mechanisms in the brain stem cardiovascular nuclei in rat models of prehepatic portal hypertension and cirrhosis. Neuronal activation in the nucleus of the solitary tract (NTS) and ventrolateral medulla (VLM) were assessed by immunohistoch...
متن کاملChronic administration of octreotide ameliorates portal hypertension and portal hypertensive gastropathy in rats with cirrhosis.
1. Portal hypertension and hyperdynamic circulation have been postulated to play a role in the pathogenesis of portal hypertensive gastropathy. Administration of octreotide to portal hypertensive rats has been shown to reduce portal pressure and ameliorate hyperdynamic circulation. 2. This study investigated the effects of chronic administration of octreotide on systemic and portal haemodynamic...
متن کاملInvolvement of constitutive nitric oxide synthase in the portal-systemic collaterals of portal hypertensive rats.
BACKGROUND Recent studies have shown that endothelial nitric oxide (NO) is involved in modulating the vascular response to vasoconstrictors in portal-systemic collaterals of portal hypertensive rats. This study investigated which isoform of NO synthase is involved in the collateral circulation of portal hypertensive rats. METHODS The relaxation response to acetylcholine (10(-8) M, 10(-7) M an...
