Disease relevance of Venous Pressure

 

Psychiatry related information on Venous Pressure

  • Inflation of a balloon at the right superior vena caval/right atrial junction of the rat causes no change in arterial or venous blood pressure but does attenuate spontaneous night-time drinking and the acute responses to 24 h water deprivation and s.c. isoprenaline [6].
 

High impact information on Venous Pressure

  • Increasing hepatic venous pressure to elevate portal venous pressure to the same level as that achieved with acetylcholine resulted in a similar increase in splanchnic vascular volume [7].
  • The increase in lobar arterial and venous pressure in response to either injected norepinephrine or to nerve stimulation was antagonized by an alpha receptor blocking agent [8].
  • METHODS: In protocol 1, 13 patients had measurements of the hepatic venous pressure gradient, hepatic blood flow, mean arterial pressure, cardiac output, and nitric oxide products before and 30 and 60 minutes after 40 mg of simvastatin [9].
  • RESULTS: In protocol 1, acute simvastatin did not modify the hepatic venous pressure gradient but increased the hepatic blood flow (21% +/- 13% at 30 minutes; P = 0.01) and decreased hepatic sinusoidal resistance by 14% +/- 11% (P = 0.04) [9].
  • METHODS: The portal vein of wild-type mice, or those with targeted mutations in the nos2 gene (iNOS) or the nos3 gene (eNOS), was ligated and portal venous pressure (Ppv), abdominal aortic blood flow (Qao), and portosystemic shunt determined 2 weeks later [10].

Associations of Venous Pressure with chemical compounds

  • Propranolol to lower portal venous pressure [26].
  • At this level vasopressin was found to increase both systemic (Pa) and local (Pma) arterial pressures while decreasing superior mesenteric venous pressure (Pv), capillary pressure (PC) and blood flow (QB) [27].
  • It is concluded that the two different doses of octreotide administration result in the reduction of the wedge hepatic venous pressure and the hepatic blood flow of a similar magnitude, whereas the hepatic venous pressure gradient is unaffected [28].
  • Prazosin decreased the hepatic venous pressure gradient (HVPG) while increasing hepatic blood flow [29].
  • While measuring arterial pressure, colonic blood flow, venous pressure, and arteriovenous O2 difference, a Tyrode's solution containing acetic (75 mM), propionic (30 mM), and butyric acids (30 mM) was placed into the colon lumen [30].
 

Gene context of Venous Pressure

  • IGFBP-3 correlated significantly with the wedged hepatic venous pressure (r = -0.49; P < 0.05), serum aspartate aminotransferase (r = -0.66; P < 0.01), serum bilirubin (r = -0.65; P < 0.01), serum albumin (r = 0.64; P < 0.01), and the Child score (r = -0.57; P < 0.01) [31].
  • Adequate liver regeneration requires an adequate increase in portal venous pressure and flow reflected by clearance of HGF and elevated VEGF levels [32].
  • The pressor response to ET-1 was determined in vitro using isolated vascular rings and in vivo by measuring mean arterial pressure, splanchnic blood flow, and portal venous pressure following treatment with ET and selective ET receptor antagonists [33].
  • There was no significant difference in the peak splanchnic blood flow or portal venous pressure response following ET-A receptor blockade with JKC-301 infusion (200 microg/kg intravenously) [33].
  • In contrast, ET-B receptor blockade with IRL-1038 (200 microg/kg intravenously) preferentially decreased splanchnic blood flow and portal venous pressure in portal hypertensive rats [33].
