[Occurrence of delayed symptoms after a challenge test with methacholine].

There are few prospective studies available on the development of delayed symptoms following challenge tests with methacholine (MCT) at the currently recommended doses. The objective of this study was to describe the nature and frequency of respiratory symptoms suggestive of bronchospasm developing within 24hours after a MCT. The study was offered to adult patients who underwent MCT seen consecutively between June and October 2015.

[Measuring and speaking about respiration. Role and ethical function of a psychopathological interview in a medical service].

On the occasion of a respiratory function exploration, it was given to the patient the possibility of evoking, in respect of freely association, the psychical sense assumed by his symptom in his history. The unity of time, place and methodology, clinical psychopathology, defined our "experimental device". When the patient of this study, with SAS, said to the physician "I forget myself" with regard to ther apneas, the symptom, spoken, referred to a construction, "complementary" (Bohr, 1927) to another one described and objectivated by medicine.

Comparisons among external resistive loading, drug-induced bronchospasm, and dense gas breathing in cats: roles of vagal and spinal afferents.

In anesthetized cats, breathing spontaneously, increase in lung resistance (RL) was induced by either external resistive loads (ERL) or internal loading produced by dense gas breathing (sulfur hexafluoride, SF6) or serotonin (5-HT)-induced bronchoconstriction. The 3 test agents were used in each animal. Arterial blood gases were maintained in the normal range.

The respiratory sensation at high altitude.

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.
