Example text

For example, in many tissues, low intracellular steadystate concentrations of superoxide occur as a result of the balance between the basal rates of partial reduction of oxygen to superoxide and the diffusion-limited scavenging of superoxide by both cytoplasmic and mitochondrial SODs, resulting in intracellular superoxide concentrations estimated to rarely exceed 1 nM (54). The extracellular release of small proportions of intracellularly formed superoxide may occur via diffusion through anion channels, and superoxide formed from plasma membrane-bound oxidases remains at relatively low levels because of the serum and extracellular fluid components, including the low molecular weight oxidant scavengers and the heparin-binding extracellularSOD (55–57).

05. 6. 1. 1. Systemic Parameters and Microhemodynamics Twenty animals were used for the study; ten received a continuous infusion of the NO scavenger and ten, a continuous infusion of the vehicle. 1 summarizes the changes in the systemic parameter response to hypoxia that caused significant changes in blood pO2, pCO2, and pH. These changes are the consequence of hyperventilation, a normal response to hypoxia. 1a. CPTIO reduced the diameter of the arterioles in normoxia. Hypoxia resulted in a statistically significant vasodilation.

Normoxic animals (Fig. 3) Hypoxia significantly increased ROS formation compared with normoxia. 4). 04 MAP (mmHg) HR (beats/min) paO2, (Torr) paCO2, (Torr) Arterial pH The mean blood pressure (MAP), heart rate (HR), pO2, arterial pO2–pCO2.
