Prevalence of achlorhydria in a normal population and its relation to serum gastrin.

In a middle-aged group of normal subjects achlorhydria after maximal stimulation with pentagastrin was found in 12 out of 366 males (3%) and 2 out of 198 females (1%); 13 of these 14 (93%) had an elevated serum gastrin, of which nine were more than two times normal. In another 11 persons a moderately elevated serum gastrin - less than two times normal - was found in absence of achlorhydria. At least seven of them had hypochlorhydria. Of 540 persons with a normal serum gastrin one had achlorhydria. Determination of the serum gastrin appeared to be fairly reliable as a method of detecting achlorhydria.

Irradiation of erythrocytes with UV light (254 nm) in doses, which increased the activity of ABO and Rh system antigens followed by a photochemical destruction of the cell surface coat (outer perimembraneous layer) and the release of its components, which were stained in situ with alcian blue vital dye to be presumably glycoproteins. The role of this phenomenon in the therapeutic effect of UV light is discussed.
