Abstract

Three tests of small intestinal function were performed at 3100 m and 4846 m to seek evidence of malabsorption of high altitude. Xylose tolerance did not change in 11 subjects but, in three who ascended to 5600 m, one-hour xylose levels were significantly lower. The results of an oxalate loading test did not suggest significant fat malabsorption. A direct fat absorption test using chylomicron levels after ingestion of 100 g fat showed significantly increased levels at high altitude. We conclude that there is no evidence of malabsorption up to 4846 m.

The effect of shear stress on the basolateral membrane potential of proximal convoluted tubule of the rat kidney.

As consequence of glomerular filtration the viscosity of blood flowing through the efferent arteriole increases. Recently, we found that shear stress modulates proximal bicarbonate reabsorption and nitric oxide (NO.) was the chemical mediator of this effect. In the present work, we found that agonists of NO. production affected basolateral membrane potential (V (blm)) of the proximal convoluted tubule (PCT) epithelium. Using paired micropuncture experiments, we perfused peritubular capillaries with solutions with different viscosity while registering the V (blm). Our results showed that a 50% increment in the viscosity, or the addition of bradykinin (10(-5) M) to the peritubular perfusion solution, induced a significant and similar hyperpolarization of the V (blm) at the PCT epithelium of 6 +/- 0.7 mV (p < 0.05). Both hyperpolarizations were reverted by L-NAME (10(-4) M). Addition of 2,2'-(hydroxynitrosohydrazino) bis-ethanamine (NOC-18) 3 x 10(-4) M to the peritubular perfusion solution induced a hyperpolarization of the same magnitude of that high viscosity or bradykinin. These results strongly suggest the involvement of NO. in the effect of high viscosity solutions. This effect seems to be mediated by activation of K+(ATP) channels as glybenclamide (5 x 10(-5) M) added to peritubular solutions induced a larger depolarization of the V (blm) with high viscosity solutions. Acetazolamide (5 x 10(-5) M) added to high viscosity solutions induced a larger hyperpolarization (8 +/- 1 mV; p < 0.05), suggesting that depolarizing current due to HCO(-)3 exit across the basolateral membrane damps the hyperpolarizing effect of high viscosity. Considering that Na(+) and consequently water reabsorption is highly dependent on electrical gradient, the present data suggest that the endothelium of kidney vascular bed interacts in paracrine fashion with the epithelia, affecting V (blm) and thus modulating PCT reabsorption.

Effect of acetazolamide on pulmonary and muscle gas exchange during normoxic and hypoxic exercise.

Acetazolamide (ACZ) is used to prevent acute mountain sickness at altitude. Because it could affect O2 transport in several different and potentially conflicting ways, we examined its effects on pulmonary and muscle gas exchange and acid-base status during cycle exercise at approximately 30, 50 and 90% VO2max in normoxia (F(IO2) = 0.2093) and acute hypoxia (F(IO2) = 0.125). In a double-blind, order-balanced, crossover design, six healthy, trained men (normoxic VO2max= 59 ml kg(-1) min(-1)) exercised at both F(IO2) values after ACZ (3 doses of 250 mg, 8 h apart) and placebo. One week later this protocol was repeated using the other drug (placebo or ACZ). We measured cardiac output (QT), leg blood flow (LBF), and muscle and pulmonary gas exchange, the latter using the multiple inert gas elimination technique. ACZ did not significantly affect VO2, QT, LBF or muscle gas exchange. As expected, ACZ led to lower arterial and venous blood [HCO3-], pH and lactate levels (P < 0.05), and increased ventilation (P < 0.05). In both normoxia and hypoxia, ACZ resulted in higher arterial P(O2) and saturation and a lower alveolar-arterial P(O2) difference (AaD(O2)) due to both less VA/Q mismatch and less diffusion limitation (P < 0.05). In summary, ACZ improved arterial oxygenation during exercise, due to both greater ventilation and more efficient pulmonary gas exchange. However, muscle gas exchange was unaffected.

Inhibition of hypoxia-induced calcium responses in pulmonary arterial smooth muscle by acetazolamide is independent of carbonic anhydrase inhibition.

Hypoxic pulmonary vasoconstriction (HPV) occurs with ascent to high altitude and can contribute to development of high altitude pulmonary edema (HAPE). Vascular smooth muscle contains carbonic anhydrase (CA), and acetazolamide (AZ), a CA inhibitor, blunts HPV and might be useful in the prevention of HAPE. The mechanism by which AZ impairs HPV is uncertain. Originally developed as a diuretic, AZ also has direct effects on systemic vascular smooth muscle, including modulation of pH and membrane potential; however, the effect of AZ on pulmonary arterial smooth muscle cells (PASMCs) is unknown. Since HPV requires Ca2+ influx into PASMCs and can be modulated by pH, we hypothesized that AZ alters hypoxia-induced changes in PASMC intracellular pH (pH(i)) or Ca2+ concentration ([Ca2+](i)). Using fluorescent microscopy, we tested the effect of AZ as well as two other potent CA inhibitors, benzolamide and ethoxzolamide, which exhibit low and high membrane permeability, respectively, on hypoxia-induced responses in PASMCs. Hypoxia caused a significant increase in [Ca2+](i) but no change in pH(i). All three CA inhibitors slightly decreased basal pH(i), but only AZ caused a concentration-dependent decrease in the [Ca2+](i) response to hypoxia. AZ had no effect on the KCl-induced increase in [Ca2+](i) or membrane potential. N-methyl-AZ, a synthesized compound lacking the unsubstituted sulfonamide group required for CA inhibition, had no effect on pH(i) but inhibited hypoxia-induced Ca2+ responses. These results suggest that AZ attenuates HPV by selectively inhibiting hypoxia-induced Ca2+ responses via a mechanism independent of CA inhibition, changes in pH(i), or membrane potential.
