[Changes in the intragastric vessels after a chemical burn]

The functional and morphological studies have proved that some considerable vascular changes occur in the injured stomach wall within the first hours after a superficial chemical burn. The most gross injuries in the arterial, venous and capillary network of the mucous occur 24 hours after the contamination with a corrosion substance. Regenerative processes in the vascular system together with functional improvement start after 3 days. Normalization of the circulation in the injured stomach wall comes about after 14 days.
