Ulcerative colitis (UC) is a inflammatory disease of large bowel. The amount of people suffering from UC increases from year to year. Pathogenesis of this affection is still not entirely clear. Mechanisms of proliferation and apoptosis in colonocytes in the course of the disease are defectedThe aim of the study was to assess the rate of proliferation and intensity of apoptosis in colonocytes in patients with diagnose UC.Material and methods. Colon pathological samples taken from patients with diagnosed ulceraive colitis were examined. Patients were in both clinical and endoscopic remission and were treated with mesalazin. They were patient of Department of General and Colorectal Surgery. To estimate proliferation index dye with monoclonal antibody against Ki67. To determine apoptosis level immunohistochemistry with antybody against Bax was used.Results. Average Ki-67 in the test group was 42,13%, the largest value amounted to 57% and the lowest of 33%. Average value of Bax was 1.47 and ranged between 0-3. High index of bax appear not only in the bottom of the crypt, but also at their outlet.Conclusions. In ulecerative colitis genetic and immunological disturbances occur despite treatment. Mesalazine acting only on certain routes associated with the UC holds the remission, without, however "the molecular remission". Thus, it appears that the results of our research are another proof of the necessary caution in weaning support treatment.
