Intestinal Gases of Man

Abstract

The APS Journal Legacy Content is the corpus of 100 years of historical scientific research from the American Physiological Society research journals. This package goes back to the first issue of each of the APS journals including the American Journal of Physiology, first published in 1898. The full text scanned images of the printed pages are easily searchable. Downloads quickly in PDF format.

Fixation of sulphur in the gut by bismuth salts

“…Under normal conditions the small intestine contains very little gas, although large quantities may accumulate in the colon. Analysis of human colonic flatus (Fries, 1906;Kirk, 1949) reveals little or no hydrogen sulphide; possibly this is because most collections of such gas have been made over water, but the low concentration of hydrogen sulphide in flatus is in any event not surprising owing to the high solubility and diffusibility of the gas (Andersen and Ringsted, 1943).…”

Potentially Explosive Colonic Gas Is Not Eliminated by Successful Mechanical Bowel Preparation

“…The volume of colonic gas pro duced each day is almost 1,000 ml [22], Hydrogen and methane are the two major combustible gases in the colon. Hydrogen is produced mainly in the colon and is almost completely dependent upon ingested fermentable substrates, primarily carbohydrates.…”

Energy balances in man

“…Very little gas is produced by fermentation in the human alimentary canal. A healthy person will pass up to I 1. of flatus daily (Fries, 1906;Alstead & Patterson, 1948). The amount of methane formed is so small that it can be neglected in drawing up human energy balances.…”
