[The effect of respiratory mechanics on the hematocrit. III. Study in patients with bronchopulmonary disease treated with intermittent positive pressure inhalation therapy].

The Authors studied the behaviour of lung volumes and mechanics and of haematocrit after intermittent pulmonary positive pressure breathing (IPPB) in patients with chronic obstructive lung disease. An improvement of obstructive sindrome at 10'-20'-40' and a contemporary decreasing of haematocrit were observed. This statistically significant modification was regarded as an expression of a different distribution of blood in lung vessels dued to an increasing of this vascular compliance and to a decrease of alveolar inflation. The Authors postulate the realization of a better circulation in lung vessels which contributes to a lowering of haematocrit in these patients perhaps for a different VA/Ob ratio.

[Plasma ion changes in venous blood incubated with beta receptor blockers and subjected to tonometry in vitro. 1. Study using propranolol].

The Authors considered the variations in electrolyte plasmatic assessment in blood samples incubated "in vitro" with propranolol (48 gamma/10 cc) and part of sample incubated with propranolol and theophyllin-ethilandiamin. The evaluation of electrolyte assessment was performed at 20'-40'-60' after tonometration. Sodium and potassium values increase in the samples with the beta-blocking agent and are statistically significant only after 20'; in further controls the increasing values persist. Chloride rises too, marked by a low statistic significance. No variations were observed in samples incubated also with propranolol and antiphosphodiestherasic agent. The Authors suggest trat data should confirm ionic transport blockage across the red cell membrane obtained with theophylline.

[Physiopathological and clinical data on post-hypercapnic metabolic alkalosis. A case of severe hypercapnia treated with drugs and in an "iron lung"].

The Authors produce a further contribution on metabolic post-hypercapnic alkalosis on the basis of clinical observation of a patient with severe hypercapnia and respiratory failure undergoing intensive care as well as treatment with iron lung (Pulmolife). The improvement of respiratory acid-base umbalance was associated with alteration of electrolytic assessment, especially of the plasmatic chloride ratio. The Authors consider this remark as a starting point for a physiopathological pattern and a more complete analysis of the pathways which generate the metabolic post-hypercapnic alkalosis condition in such patients.
