Intrarenal transport and vasoactive substances in hypertension.
Blood pressure is influenced by several vasoactive factors that also regulate nephron transport. An imbalance in regulation of salt reabsorption by the nephron contributes to hypertension. In the spontaneously hypertensive rat (SHR), the responses to dopamine and angiotensin II in the proximal nephron are diminished and enhanced, respectively. This partially explains why the proximal tubule of ...
متن کاملPrednison provokes serum and vasoactive substances in a mice model of immune thrombocytopenia
Objective(s): The main objective of this study was to investigate the variations of β-endorphin (β-EP), vasoactive intestinal peptide (VIP), serotonin (5-HT) and norepinephrine (NE) of immune thrombocytopenia (ITP) mice as well as the regulatory mechanism of prednison. Materials and Methods: Sixty BALB/c mice were randomly divided into control group, model group and prednison intervention grou...
متن کاملInvolvement of vasoactive substances in hemodynamics disturbances in cirrhosis
Cirrhosis is a pathological entity characterized by the association of hepatocyte necrosis, fibrosis and regenerative nodules; hemodynamic and neurohormonal metabolic factors intervening in its development mechanisms, resulting in hepatic stellate cell activation and transformation and development of liver fibrosis. Cytokines are key modulators of liver cell fibroblast transformation. Prostagla...
متن کاملVasoactive substances in blood and urine of DCA hypertensive rats.
• H. Croxatto et al. have demonstrated that on incubation for 24 hours at 38 C. and pll 3.8 to 4, the serum of each of the animals they studied (including mammals, birds, and amphibia) produced a peptide which causes smooth muscle contraction. This peptitle: lias been named "auephrotonsin.'' Slight pharmacological differences were found among the anephrotensins obtained from the. several types ...
