title: [Comparison of bioassay methods of gastrin by means of a pH meter and anti-log amplifier].
abstract: For the study of gastric acid secretion, pH lowering of gastric juice has been used. In this study, an anti-log amplifier was used to measure the amount of acid secreted in rats in response to a pentagastrin injection and the accuracy was compared with the conventional method.
