The respiratory sensation was studied in Nepal at four different altitudes, 1377 m before and after the ascension, 2800 m, 3900 m and 530 m. Dyspnea was noted at each altitude for the nine subjects. They had to rate 4 external resistive loads between 2.5 and 13 cm H2O.l-1.s, presented in 2 pairs, a low and a high one. The discrimination between the loads(More)
Respiratory sensation was studied in European low-landers at an altitude of 4382 m after a helicopter flight in order to investigate the acute and prolonged effects of high altitude hypoxia. At rest the ability to detect four inspiratory resistive loads can be used to create a sensitivity index P(A) without taking the response bias (B) into account, based(More)
Biochemical, histological, and crystallographic studies were carried out on basal pancreatic secretion of 4 dogs fed alcohol for 12-15 months and 11 control dogs. The results in alcohol-fed dogs when compared to normals showed that: (1) protein concentration was higher, (2) fluid was decreased; (3) conductivity was decreased leading to differences in ionic(More)
Persisting modifications induced by repeated intravenous calcium infusion (acute hypercalcaemia) were investigated in 6 Thomas fistula dogs: 4 controls and 4 calcium-treated dogs, two of which were studied as controls. (a) The pancreatic response to graded doses of synthetic secretin (water and bicarbonate outputs) was significantly reduced in(More)
Modifications of pancreatic secretion induced by the infusion of alcohol were investigated in seven Thomas fistula dogs. Acute intravenous injections of low doses of alcohol induced a significant increase of all parameters of pancreatic secretion. On the contrary the acute intravenous injection of high doses of alcohol induced a significant decrease of(More)
Biochemical, histological and crystallographic studies were carried out on the pure exocrine pancreatic juice of calcium treated dogs and of normal dogs. 1. A long-lasting effect of repeated intravenous calcium injections was observed on the protein basal secretion (output and concentration) with intraductal plug formation. 2. The ionic equilibrium was(More)
When dogs have free access to the outside, an intravenous injection of ethanol depresses secretin-stimulated exocrine pancreatic secretion by a vagally mediated mechanism. This was shown in two separate series of six and seven dogs each. When dogs were kept in air-conditioned windowless kennels, the response to a meal was unchanged but the response to(More)
A discourse analysis was carried out on nine European lowlanders during a 2-month scientific expedition at high altitude including a 3-week stay in extreme survival conditions at the summit of Mt. Sajama (6542 m), in order to contribute to the understanding of psychological adaptation to extreme environments. This discourse analysis was part of a(More)
The effects of repeated intravenous calcium administration on pancreatic juice secretion were investigated in four Thomas fistula dogs. During stimulation by 1.0 U kg-1h-1 GIH secretin, three Ca doses were administered: 2, 4 and 8 mu mol kg-1 min-1 during 1 h, saline being used in control tests; one dose only was tested per day. It was found that Ca(More)
