15 صفحه اولEffect of chlormadinone acetate, a synthetic progesterone, on hypoxic ventilatory response in men.
Ten healthy young males were studied with a double-blind, cross-over trial to determine whether or not chlormadinone acetate (CMA), a potent synthetic progesterone, augments hypoxic chemosensitivity. Seven days after CMA administration, inspiratory minute volume (VI) and tidal volume (VT) significantly increased. PaCO2 decreased by 3.0 +/- 2.6 (S.D.) Torr (p less than 0.05) and plasma bicarbona...
متن کاملProtective Effect of Hypoxic Preconditioning on Hypoxic-Ischemic Injured Newborn Rats
Brief episodes of cerebral hypoxia-ischemia cause transient ischemic tolerance to subsequent ischemic events that are otherwise lethal. This study was conducted to evaluate the protective effect of hypoxic preconditioning on hypoxic-ischemic injury in the neonatal rat and the persistence of a protective window after hypoxic preconditioning. The rats were preconditioned with hypoxia (8% oxygen, ...
متن کاملTime domains of the hypoxic ventilatory response.
The ventilatory response to hypoxia depends on the pattern and intensity of hypoxic exposure and involves several physiological mechanisms. These mechanisms differ in their effect (facilitation or depression) on different components of ventilation (tidal volume and frequency) and in their time course (seconds to years). Some mechanisms last long enough to affect future ventilatory responses to ...
متن کاملEffect of hypoxic episode number and severity on ventilatory long-term facilitation in awake rats.
Episodic hypoxia induces a persistent augmentation of respiratory activity, termed long-term facilitation (LTF). Phrenic LTF saturates in anesthetized animals such that additional episodes of stimulation cause no further increase in LTF magnitude. The present study tested the hypothesis that 1) ventilatory LTF also saturates in awake rats and 2) more severe hypoxia and hypoxic episodes increase...
