pH measurements were recorded from the mucosal surfaces of the rat forestomach and glandular stomach following stimulation of acid-secretion by pentagastrin. Animals containing a normal gastric bolus showed lower forestomach acidity (pH 4.3, cf. 3.2) as did coprophagic animals that contained a fecal gastric bolus (pH 6.0, cf. 3.6). Animals without a gastric bolus showed higher forestomach acidity (pH 2.3, cf. 3.0). It is concluded that the presence of a food bolus is prerequisite to maintenance of lower forestomach acidity in rats.
在用五肽胃泌素刺激胃酸分泌后，记录大鼠前胃和腺胃黏膜表面的pH值。含有正常胃食团的动物前胃酸度较低（pH 4.3，对比3.2），而含有粪便性胃食团的食粪动物也是如此（pH 6.0，对比3.6）。没有胃食团的动物前胃酸度较高（pH 2.3，对比3.0）。得出的结论是，食团的存在是维持大鼠前胃较低酸度的先决条件。
