Expression of NADPH-diaphorase (NOS) in rat hypothalamo-neurohypophysial system after ischemic and traumatic brain injury.
: To investigate the sites of nitric oxide synthase (NOS) expression after brain injury, NADPH-d histochemistry was performed on the hypothalamo-neurohypophysial system (HNS) of adult rats several days after both ischemia and trauma. Electron-microscopic examination revealed the sites of formazan end-product of the diaphorase reaction i.....
