title: A new method of producing chronic gastric fistula and collection of gastric juice in rats.
abstract: A method of producing chronic gastric fistula and collection of gastric juice in rats. Acta Physiol. Pol., 1978, 29 (1): 79-86. A kind of material suitable for making different parts of the gastric fistula as well as their shape and size have been established. Organic glass (plexiglas) was used for making the cannula. A twisted-on cap of stainless steel protected the mouth of the fistula. This cap secured also the possibility of directly attaching a vessel for collection of gastric juice to the orifice of the cannula. The vessel was made of plexiglas and owing to its shape and dimensions it did not impede the rat's movements during the investigations. A disc of nylon net glued on to the external wall of the cannula prevented leaking of the fistula and its consequences. The fistula produced in this way showed a considerable durability and the vessel made it possible to investigate gastric secretion in a freely moving animal under physiological conditions or under any chosen experimental conditions.
