Biography Historical Article Classical ArticleThe immersion foot syndrome. 1946.
1. Prolonged exposure of the extremities to cold insufficient to cause tissue freezing produces a well-defined syndrome. 'Immersion foot' is one of the descriptive but inaccurate terms applied to this syndrome. The clinical features, aetiology, pathology, prevention, and treatment of immersion foot are considered in detail. ⋯ During the period of the study, one of us (R. L. R.) was in receipt of a personal grant from the Medical Research Council.

Randomized Controlled Trial Clinical TrialLack of effect of Rhodiola or oxygenated water supplementation on hypoxemia and oxidative stress.
This study investigated the effects of 2 potentially "oxygen promoting" dietary supplements on hypoxia and oxidative stress at a simulated altitude of 4600 m. ⋯ The 2 dietary supplements investigated did not have a significant effect on blood oxygenation after 60 minutes of sedentary hypoxic exposure. Hypoxia-induced oxidative stress was observed in the control group only. Both supplements appeared not to increase oxidative stress and may decrease free radical formation after hypoxic exposure compared with the control.
