Increase in plasma nitric oxide end products following rat cortical injury.
The changes in plasma nitric oxide (NO) end products, nitrite (NO2-) and nitrate (NO3-), were studied following cortical injury in rats. At 3 days after stereotactic cortical injury (day 3), plasma NO end products were significantly increased (P < 0.01), and decreased by day 7. This increase on day 3 was inhibited by a selective inhibitor of inducible NO synthase (NOS), aminoguanidine (100 mg/kg, i.p. on days 1 and 2, P < 0.001). The present study first demonstrated the temporary increase in plasma NO end products, which is attributable to the inducible NOS activation after cerebral injury.
