EFFECTS OF HIGH CONCENTRATIONS OF CARBON DIOXIDE AND DIET ON URINARY EXCRETION OF STEROIDS AND CATECHOLAMINES, (2006)

Ulvedal,Frode, Cutler,R.G., Welch,B.E.

Air Force pilots were exposed to inspired tra cheal PCO2 of 21 mm. Hg (BTPS) at 700 mm. Hg and 200 mm. Hg cabin pressure. Each exposure was of 4 days' duration and was preceded in each case by a...

STEROID AND CATECHOLAMINE STUDIES ON PILOTS DURING PROLONGED EXPERIMENTS IN A SPACE CABIN SIMULATOR. (2005)

Ulvedal, Frode, Smith, Woodard R., Welch, Billy E.

Urinary excretion of 17-OHCS, corticosterone-like hormones, and catecholamines was investigated in pilots during prolonged experiments in a two-man space cabin simulator. The experimental profiles...

PRELIMINARY OBSERVATIONS ON TESTICULAR FUNCTION IN ROOSTERS AND MICE EXPOSED TO INCREASED PARTIAL PRESSURE OF OXYGEN. (1998)

Ulvedal, Frode

Adult White Leghorn roosters were exposed to 100% oxygen atmospheres at 258 and 380 mm. Hg pressure for 31 and 22 days, respectively. A ground-level control experiment was also performed. Ejaculates...

GROWTH OF THE YOUNG MALE RAT IN A HYPEROXIC ENVIRONMENT. (1998)

Bartek,Methodius J., Daniels,Murphy B., Ulvedal,Frode

Young male rats were maintained continuously in a hyperoxic environment for periods up to 8 weeks. During this time, the animals were subjected to an oxygen partial pressure of 369 mm. Hg (97.1%) at...

FLAME PROTECTION AFFORDED MICE BY A NONCOMBUSTIBLE GARMENT IN 100% OXYGEN ATMOSPHERES. (1998)

Hargreaves,John J., Ulvedal,Frode

Thirty-nine mice, with hair clipped or unclipped, were clothed in a noncombustible garment, Beta cloth, and subjected to flame ignition in 100% oxygen atmospheres from 744 to 190 mm. Hg total...

PHYSIOLOGIC AND BIOCHEMICAL OBSERVATIONS ON THE RHESUS MACACA MULATTA EXPOSED TO OXYGEN-RICH ATMOSPHERES. (1998)

Ulvedal,Frode, Brown,H. E.

Adolescent male rhesus monkeys (Macaca mulatta), weighing 2.9 to 3.4 kg., were exposed to 100% oxygen atmospheres at 258 and 380 mm. Hg pressures for 30 and 22 days, respectively, and the results...

Effects of Oxygen and Decreased Total Pressure on Testicular Function in the Rabbit. (1998)

Russell,Robert John, Ulvedal,Frode

This investigation examined the effects of increased partial pressure of oxygen at reduced total pressure (380 mm. Hg) on testicular function in the rabbit. Ejaculates were collected with an...
