[The expression of COX-1 and COX-2 following brain injuries].

Cyclooxygenase (COX) is the obligate, rate-limiting enzyme for the conversion of arachidonic acid into prostaglandins, which mediate mitogenesis, apoptosis, angiogenesis, blood flow, secondary injury, and inflammation. COX is consist of 2 subtypes: COX-1 and COX-2. In recent years, there are a number of lines of evidence that COX-1 and COX-2 play a important in role brain injuries.
