The main result of esophagus burn is the formation of scars, that caused by excessive synthesis of collagen and changes the balance of metalloproteinases and their tissue inhibitors. It was studied the activity of proteolytic enzymes, participation of MMP (metalloproteinase) and their tissue inhibitors (TIMP) in alkali burns of the esophagus 1st and 2nd degrees. We have shown a significant increase of TIMP level in homogenate after alkali burns of the esophagus (an average of 31-56% depend on of burn degree). We observed a reduced activity of serine proteinase after 1st degree burns on 15th, 21st day 35 and 18% respectively, after burns 2nd degree on 15th, 21st day 54 and 50%. The decrease of activity MMP after 1st degree burns on 15th and 21st day 30, 19%, respectively, in conditions of chemical burns 2nd degree on 15th and 21st day 30, 37%. These data may indicate the development of scarring after burn simulation of 2nd degree. Further investigation of the MMP and TIMP in the process of wound healing can be useful in creating effective approaches to prevent formation of post scarring of the esophagus.

Keywords: caustic burns of the esophagus; matrix metalloproteinases; tissue inhibitor of metalloproteinases.
