Immunoexpression of cyclooxygenase-1 and -2 in ulcerative colitis

Immunoexpression of cyclooxygenase-1 and -2 in ulcerative colitis.

Ulcerative colitis (UC) is a disease of the colon and rectum characterized by a nonspecific chronic inflammation mediated by the concerted response of cellular and humoral events. Prostaglandins are synthesized by cyclooxygenase (COX)-1 and -2 and exhibit both pro- and anti-inflammatory activity. To evaluate COX-1 and COX-2 immunoexpression in 42 cases of UC and to correlate it with clinicopath...

Pulmonary function in ulcerative colitis

 Abstract Background: Pulmonary involvement in ulcerative colitis (UC) is thought to be rare. There is not a definite document about the question that "Is the lung a target organ in inflammatory bowel disease?" The aim of the present study is to compare lung function between cases with UC and healthy controls. This study will also be of interest about searching the outbreak of pulmonary functio...

SURGICAL TREATMENT OF ULCERATIVE COLITIS

This is a preliminary report of 28 patients with ulcerative colitis who we surgically treated with "J" pouch endorectal pull-through operation from 1978 to 1996. All patients are continent with a median stool frequency of 4 times per day, no night soilage. low postoperative complications and one mortality due to pulmonary embolism.

Cyclooxygenase-2 immunoexpression in breast cancer: progesterone receptor influence.

BACKGROUND In breast cancer cyclooxygenase-2 overexpression is related with poor outcomes, but the clinical relevance of cyclooxygenase-2 is still unclear. Progesterone receptor is a regulator of cyclooxygenase-2 expression. We postulate that progesterone receptor was associated to cyclooxygenase-2 expression and clinicopathologic factors in breast cancer. METHODS Cyclooxygenase-2 and progest...
