Objective(s):This study was carried out to investigate the effects of COX-2 selective inhibitor (Celecoxib) or non-selective COX inhibitor (Ibuprofen) on gastrointestinal motility. Materials and Methods: The rats were randomly divided into five groups including: intact, sham, traumatic brain injury (TBI) group (intact rats under TBI), Celecoxib group (10 mg/kg), Ibuprofen group (10 mg/kg). Rats...
Using a highly metastatic mammary tumor cell line that expresses both cyclooxygenase (COX) isoforms, we now show that oral administration of either a selective COX-2 inhibitor (celecoxib) or a selective COX-1 inhibitor (SC560) to mice with established tumors results in significant inhibition of tumor growth. Administration of the dual inhibitor, indomethacin, leads to even better growth control...
Coxibs such as celecoxib, rofecoxib and valdecoxib are introduced as selective COX-2 inhibitors to the market. It has been reported that inhibition of COX-2 beside traditional effects of NSAIDs, reduces the risk of colorectal, breast and lung cancers and slow the progress of Alzheimer’s disease. Zarghi et al. reported 8-benzoyl-2-(4-(methylsulfonyl)phenyl)quinoline-4-carboxylic acid (AZGH 102) ...
Nonsteroidal anti-inflammatory drugs (NSAIDs) induce gastrointestinal ulceration as the adverse reaction. This effect of NSAIDs is attributable to endogenous prostaglandin (PG) deficiency caused by inhibition of cyclooxygenase (COX), yet the relation between COX inhibition and the gastrointestinal ulcerogenic property of NSAIDs remains controversial. Using selective COX inhibitors, we examined ...

Takahashi, Yasushi, Christine Roman, Sylvain Chemtob, Mary M. Tse, Emil Lin, Michael A. Heymann, and Ronald I. Clyman. Cyclooxygenase-2 inhibitors constrict the fetal lamb ductus arteriosus both in vitro and in vivo. Am J Physiol Regulatory Integrative Comp Physiol 278: R1496– R1505, 2000.—Nonselective cyclooxygenase (COX) inhibitors are potent tocolytic agents; however, they also have adverse ...
Prostaglandins (PGs) are arachidonic acid metabolites produced by the action of the enzyme cyclooxygenase (COX). Although PGs are important mediators of inflammation in various diseases, they also are key factors in the physiological regulation of gastrointestinal and renal homeostasis. The finding that two distinct COX isoforms are responsible for PG synthesis has provided basis to the opposit...
BACKGROUND Cyclooxygenase 2 (COX-2), an inducible prostaglandin synthase, participates in inflammatory and neoplastic processes. It is expressed by various tumours and contributes to carcinogenesis. Notably, COX-2 inhibitors appear to have tumour suppressor effects and are being evaluated in clinical trials. AIMS To investigate COX-2 expression in nasopharyngeal carcinoma (NPC), a common tumo...
