Abstract

The structural basis of ulcer perforation and bleeding was determined, based on morphological evaluation of gastroduodenal ulcers. The effects of low-intensive laser irradiation LILI and LED irradiation on pathomorphosis of ulcers were studied. It was found that the local phototherapy with LILI and LED increases the relative fraction volume — RFV of fibroblasts and connective tissue fibers, reduces RFV of cell-free zones, which contributes to “strengthening” of the ulcer walls and prevents their perforation. These same photo-infllead to an increase of RFV of blood vessels, indicating inappropriateness of their use for local phototherapy in bleeding ulcers.
