The effects of oxygen inhalation for 48 h on the antioxidant capacity of lungs, livers, and brains in normal and vitamin E-deficient rats at various ages were examined. The activity levels of catalase, glutathione peroxidase, and superoxide dismutase, and the level of vitamin E in tissue homogenates were assayed as the indices of antioxidant capacity. Oxygen inhalation mostly decreased antioxid...
More accurate methods for monitoring cerebral blood flow, oxygen, and glucose metabolism with results of their application in human volunteers are described. Subjects with various types of cerebral vascular disease showed decreased cerebral blood flow and oxygen and glucose metabolism but anaerobic glycolysis appeared to be increased. Inhalation of 100% oxygen decreased anaerobic glycolysis, an...

Background: Pulmonary hypertension is a frequent complication of severe chronic obstructive pulmonary disease (COPD) and a major cause of morbidity and mortality in this condition. Based on the improved survival of these patients due to long term oxygen therapy and the potent and selective pulmonary vasodilation by inhaled nitric oxide, the safety and effectiveness of the combined inhalation of...
Context Periodontal surgical procedures produce varying degree of stress in all patients. Nitrous oxide-oxygen inhalation sedation is very effective for adult patients with mild-to-moderate anxiety due to dental procedures and needle phobia. Aim The present study was designed to perform periodontal surgical procedures under nitrous oxide-oxygen inhalation sedation and assess whether this tech...
BACKGROUND AND PURPOSE Tracer studies have demonstrated that 100% oxygen inhalation causes a small cerebral blood flow (CBF) decrease. This study was performed to determine whether arterial spin-labeling (ASL), a noninvasive MR imaging technique, could image these changes with clinically reasonable imaging durations. MATERIALS AND METHODS Continuous ASL imaging was performed in 7 healthy subj...
In mothers nursed in a semi-recumbent position, arterial oxygen tension was measured at the beginning and END OF AN an intermittent period of inhalation, Lasting for six contractions, during the first stage of labour. Ten mothers had methoxyflurane 0.35 per cent and air, followed by methoxyflurane 0.35 per cent with approximately 50 per cent oxygen. Another 10 mothers had 50 per cent nitrous ox...
The effect of oxygen inhalation at atmospheric pressure and Naftidrofuryl infusion (N) on the TCpO2 is shown. At the central control site--5 cm below the midclavicular line--oxygen inhalation produced a significant increase in TCpO2, whereas there was no change after Naftidrofuryl infusion. At the 10 cm below-knee site, there were significant rises after oxygen inhalation alone, Naftidrofuryl a...
