Representative photomicrographs showing immunolabeling of eNOS and nNOS in the cerebral cortex of rats. ac Show sections of sham, study (group II) and sumatriptan pretreatment groups (group III), respectively. Above photomicrographs of eNOS staining by immunohistochemistry. Below photomicrographs of nNOS staining by immunohistochemistry (as indicated by the asterisks). Significant positive immunolabeling was detectable in tissues from group II animals and a slight immunolabeling in group III (×20)
