[Effect of upright tilt on venous hemodynamics in rat after three-week tail suspension].
The aim of this work was to know if the venous tone measured in vivo in rat was decreased after 3-week tail suspension, a ground-based model to simulate the effects of microgravity. Arterial and venous pressure measurements during upright tilt did not show any cardiovascular deconditioning. A longer period of tail suspension appears to be necessary to induce changes in venous tone.
