Profile of gallbladder diseases diagnosed at Afyon Kocatepe University: a retrospective study.

Objective: Gallbladder is one of the most commonly encountered specimen in a pathology laboratory. A diverse spectrum of diseases affect the biliary system, often presenting with similar clinical signs and symptoms. We aimed to define the profile of gallbladder diseases in our region, and to determine potential correlations between histopathologic features we observed.

Expression of cyclooxygenase-1 and 2 in chronic tonsillitis.

Objectives: Prostaglandins are critical mediators of inflammation and affect both humoral and cell-mediated immune responses. Recent findings show that T and B cells express COX-2 upon activation. The purpose of this study is to investigate the potential occurrence of COX-1 and COX-2 immunoreactivity in cases of chronic tonsillitis and to determine the sites of their expression.
