The cellular environment of the central nervous system (CNS) is dominated by the ubiquitous presence of star-shaped glia cells. When first described by Rudolph Virchow in 1858, what he termed neuroglia were initially thought to be a form of connective tissue, the abundance of which simply served to hold neurons together like …
WebCOX-2 inhibitors are as effective as other NSAIDs at reducing pain and inflammation. However, they cause fewer stomach and intestinal problems, such as bleeding and ulcers. Only one COX-2 inhibitor is available in the U.S., celecoxib (Celebrex). You and your healthcare provider will discuss if a COX-2 inhibitor is the right NSAID choice for you. WebThe cyclooxygenases are heme-containing enzymes that convert arachidonic acid to prostaglandin H 2. Cyclooxygenase-1 (COX-1) is a constitutive enzyme, while cyclooxygenase-2 (COX-2) is inducible by cytokines, glutamate, growth factors, PAF and other mediators, and is inhibited by glucocorticoids.
