[A new method of collection of gastric juice from small animals]

A new method is suggested to obtain gastric juice in small animals. This technique is considered to be preferable in comparison with other known techniques as it permits obtaining gastric juice without surgery which is inevitably associated with such unfavourable factors as tissue traumas, pain irritation, inflammation, etc. According to the described technique the gastric juice is collected with the presence of stimulus (dry substance) in the gastric cavity. The animals are not fixed in this case but maintained under ordinary conditions. So, the obtained juice corresponds better to that produced in small animals under physiological conditions than the juice obtained using fistula or by another technique applied up to now.
