Chromoscopy of the stomach with hyperacid conditions

Chromoscopy as a diagnostic method for violations of the secretory function of the stomach was introduced into the clinic almost simultaneously by the Austrian doctors Saxl and Scherf and the Germanic Glessner and Wittgenstein in 1925, but since Saxl and Scherf, although they were the first to publish their method, they worked with an insufficiently suitable indicator (methylene blue) and appeared in the less widespread press, and Glessner and Wittgenstein used a more successful neutralroth paint and published the method in the leading German press, then they remained priority in this matter. The results of their observation are as follows: neutralrot is not salivated, in a normal stomach it is shown after 15 minutes, with subacid values ​​of gastric secretion, the coloring matter is released after 20-60 minutes, and with anacid secretion it is not released at all.
