The mechanism of proteinuria at high altitude is unclear. Renal function and urinary excretion rate of albumin (Ualb) at rest and during submaximal exercise and transcapillary escape rate of 125I-labeled albumin (TERalb) were investigated in 12 normal volunteers at sea level and after rapid and
High-altitude pulmonary edema (HAPE), a severe form of altitude illness that can occur in young healthy individuals, is a noncardiogenic form of edema that is associated with high concentrations of proteins and cells in bronchoalveolar lavage (BAL) fluid (Schoene et al., J. Am. Med. Assoc. 256:
Rapid ascent to altitude risks the development of acute mountain sickness. This study demonstrates changes in peripheral capillary filtration coefficient and renal protein loss in subjects suffering from various degrees of mountain sickness after passive ascent to 4559 m. Capillary filtration
OBJECTIVE
High altitude pulmonary oedema can be successfully treated and prevented by calcium channel blockers. Moreover, calcium entering in the cells could explain the congestive phenomena of acute mountain sickness (AMS). These findings led us to study the action of a calcium channel blocker,
Heart output distribution (HO) was characterised by incorporation of 15-micron 131-I [correction of 15- 131J]-albumin microspheres after cooling and altitude hypoxia in alert rats. There was no significant change in the HO distribution in experimental rats except a 1.5-fold increase of the skin HO
The purpose of the present study was to evaluate the nutritional status of children based on anthropometric measurements, biochemical indicators of protein energy malnutrition as well as hematological variables. The subjects were 93 10- to 12-year-old Bolivian boys: 12 HAHSES, 28 HALSES, 36 LALSES,
The transfer of male dogs from lowlands to an altitude of 3370 m was accompanied by hypoproteinemia and reduction of albumins and beta-globulins, stable increase of activity of alanine aminotransferase, decrease of activity of alkaline phosphatase and content of phosphate. This can be interpreted as
Albumin was measured by dipstick tests and immunologically in 24-h and early morning urine (EMU) samples collected from 20 subjects during a high-altitude trek. Each was given acetazolamide (Diamox sustets) or placebo as part of a double-blind trial on the prophylactic use of acetazolamide in acute
Renal function and the urinary excretion rate of albumin (Ualb) at rest and during infusion of dopamine (3 micrograms kg-1 min-1) were investigated in eight normal volunteers at sea level and 48 h after a rapid, passive ascent to an altitude of 4350 m. Oxygen saturation decreased to 81% (77-85)
A potential pathogenetic cofactor for the development of acute mountain sickness and high-altitude pulmonary edema is an increase in capillary permeability, which could occur as a result of an inflammatory reaction and/or free radical-mediated injury to the lung. We measured the systemic albumin
