Effect of endothelin on plasma volume and albumin escape.
Previous studies have demonstrated that endothelin-1 (ET-1) is a potent vasoconstrictor that decreases cardiac output and increases hematocrit. The present study was designed to determine if the rise in hematocrit and decrease in cardiac output are in part due to shifts of plasma from the vascular space to the interstitial space. Red blood cell volume and plasma volume were determined by using ...
متن کاملEstimation of plasma volume from hematocrit and plasma oncotic pressure during volume expansion in dogs.
Changes in hematocrit and plasma oncotic pressure were measured continuously during and after isotonic volume expansion in splenectomized dogs in order to test the potential of these types of measurements to predict changes in plasma volume. A volume of Ringer's solution amounting to 15% of the initial blood volume was infused over 10 min. At the end of the infusion, 54% of infused fluid remain...
متن کاملAcute plasma volume expansion: effect on metabolism during submaximal exercise.
To examine the effect of acute plasma volume expansion (PVE) on substrate selection during exercise, seven untrained men cycled for 40 min at 72 +/- 2% peak oxygen uptake (VO(2 peak)) on two occasions. On one occasion, subjects had their plasma volume expanded by 12 +/- 2% via an intravenous infusion of the plasma substitute Haemaccel, whereas on the other occasion no such infusion took place. ...
متن کاملHemodynamic effects of anemia with and without plasma volume expansion.
Hypervolemic anemia and normovolemic anemia were produced in dogs. Cardiac outputs increased comparably with similar degrees of anemia in the hypervolemic and normovolemic animals. No significant association between light atrial mean pressure and cardiac output was found. Right atrial and pulmonary arterial pressures increased in a degree comparable to blood volume increase. Systemic mean press...
متن کاملEndothelin-1 enhances the melanogenesis via MITF-GPNMB pathway
Endothelin-1 (ET-1) plays an indispensable role in epidermal pigmentation in hyperpigmentary disorders due to a central role in melanogenesis. Nevertheless, precise mechanism involved in ET-1-induced hyperpigmentation is still undefined. Glycoprotein (transmembrane) non-metastatic melanoma protein b (GPNMB) is a key element in melanosome formation. Therefore, we speculated that GPNMB was correl...
