Cambridge Spitsbergen Expedition, 1977

Autumn meeting, cambridge, 16 and 17 september 1977.

Birmingham Medical Research Expeditionary Society 1977 Expedition: serum and urine proteins during a high altitude trek.

Serum and urine proteins were measured daily in 17 subjects undertaking a typical high altitude Himalayan trek. Marked changes occurred in a variety of serum proteins as a result of plasma volume alterations and 'stress'. There was only a sporadic increase in proteinuria. None of the changes was related to the development of acute mountain sickness.

Comparison and significance of auroral studies during the Swedish and Russian bilateral expedition to Spitsbergen in 1899–1900

Results of measurements and visual observations of aurora at Spitsbergen, carried out by the joint SwedishRussian expedition during 1899–1900, are described. Auroral observations took place during the great bilateral Arc-ofMeridian expedition, which was patronized by the Swedish Royal Family and the Russian Imperial Family. The RussianSwedish Arc-of-Meridian measurements were closely coordinate...

Birmingham Medical Research Expeditionary Society 1977 Expedition: cardiopulmonary function before, during and after a twenty-one-day Himalayan trek.

The heart rate response to exercise was studied in 17 normal subjects before, during and after a 21-day Himalayan trek to 5490 m. The group were fitter before the trek when compared to normal subjects of a similar age (P less than 0.001) having a lower heart rate response to exercise for their lean body mass. The trek significantly increased the 'fitness' of the group as a whole (P less than 0....

Birmingham Medical Research Expeditionary Society 1977 Expedition: the diuresis and related changes during a trek to high altitude.

Continuous 24-hr urine collections were made by 17 subjects during a trek to 5400 m. Fluid intake was recorded by diary. Weight and fat folds were measured daily. The results were compared with daily measurements of packed cell volume (PCV) and reticulocyte count. Early fluid retention was matched by a fall in PCV. There was a diuresis with negative fluid balance towards the end of the ascent a...
