Abstract
A 1% emulsion of mustard oil in water is a comparatively poor stimulus for gastric mucus secretion. It is an active mucosal irritant, giving rise to large amts. of a secretion which consists for the most part of serous transudate (or exudate). The persistently low viscosity, low order of opacity, low incidence of columnar cells, and probable small mucin content all indicate that mustard oil in this conc. fails to evoke the usual responses of a true mucus stimulus. On the other hand, the high vol., rate, and duration of secretion; the resemblance in color of early specimens to blood plasma; the almost invariable appearance of fresh blood, increasing in intensity with progress of the expt., together with the observations on viscosity, opacity, etc., support the view that the secretion is a transudate or exudate. Some mucus is present in the secretion.
