13. An analysis of the physiological strain of submaximal exercise in patients with chronic obstructive bronchitis.
An increasing work rate was performed by 40 patients with chronic obstructive bronchitis, split into two groups according to FEV1 (group M, mean FEV1 1-451. and group S, mean FEV1 0-621.), and by 20 normal, non-athletic men of similar age to the patients. Values for cardiac frequency and ventilation were interpolated to standard oxygen uptakes of 0-75, 1-0,

14. Detoxification of hydrogen sulfide and methanethiol in the cecal mucosa
Colonic bacteria liberate large quantities of the highly toxic gases hydrogen sulfide (H2S) and methanethiol (CH3SH). The colonic mucosa presumably has an efficient means of detoxifying these compounds, which is thought to occur through methylation of H2S to CH3SH and CH3SH to dimethylsulfide (CH3SCH3). We investigated this detoxification pathway by incubati

15. Haemodynamic effects of pressure support and PEEP ventilation by nasal route in patients with stable chronic obstructive pulmonary disease.
BACKGROUND--Intermittent positive pressure ventilation applied through a nasal mask has been shown to be useful in the treatment of chronic respiratory insufficiency. Pressure support ventilation is an assisted mode of ventilation which is being increasingly used. Invasive ventilation with intermittent positive pressure, with or without positive end expirato
