Recycle of L-citrulline to form L-arginine in cerebral perivascular nerves has been well described, providing direct evidence that nitric oxide (NO) is synthesized and released from these nerves to act as the transmitter for vasodilation. NO is also synthesized and released from cerebral endothelial cells, involving L-citrulline conversion to L-arginine. Evidence for the presence of enzymes involved in the conversion, however, has not been shown. The presence of nitric oxide synthase (NOS) , argininosuccinate synthetase (ASS) , and argininosuccinate lyase (ASL) , and their coexistence with NADPH-diaphorase (NADPHd) , a marker for NOS, in endothelial cells of middle cerebral arteries and the circle of Willis of the pig, therefore, were examined using combined immunohistochemical and histochemical techniques. NOS-, ASS-, and ASL-immunoreactivities were found in almost all endothelial cells of all cerebral arteries examined. All ASS-, ASL-, and NOS-immunoreactive
