BACKGROUND Capsaicin-sensitive nerve fibres protect gastrointestinal mucosa in animal models of mucosal injury by modulation of mucosal blood flow and mucus secretion. The aim of our study was to evaluate the effects of capsaicin-sensitive nerve fibres in rat colonic mucosa on epithelial cell proliferation and transforming growth factor-alpha (TGFalpha)(More)
BACKGROUND Epidermal growth factor (EGF) and transforming growth factor (TGF)-alpha protect the gastrointestinal mucosa against injury. In response to mucosal injury TGF-alpha, but not EGF, is locally increasingly expressed in the mucosa of the rat colon and stomach 4-8 h after injury. The aim of our present study was to characterize the possible signal for(More)
The study was carried out with juvenile European catfish to evaluate the effects of commercial diets on growth, feed utilization and changes of selected morphometric traits of fish. Three diets containing different levels of crude protein and lipid: 37 and 12 %, 45 and 15 %, 45 and 20 %, respectively, were fed to triplicate groups of European catfish for 50(More)
