In the preoptic nucleus (PON) of the goldfish, Carassius auratus, four types of cells were observed under a light microscope: cells showing colocalization of immunoreactive angiotensin II (ANG II) and immunoreactive agrinine vasopressin (AVP), cells with only ANG II-like immunoreactivity, cells with only AVP-like immunoreactivity and cells with neither immunoreactivity. Under an electron microscope, only two types of nerve terminals were found in the neurohypophysis: those showing immunoreactivity of both antisera and those with neither immunoreactivity. No terminals showing alternative immunoreactivity could be found. The discrepancy in these findings obtained by light and electron microscopes is discussed. In nerve terminals reactive to both antisera, an immunogold technique indicated the presence of neurosecretory granules with colocalization of immunoreactive ANG II and AVP, granules with only ANG II-like immunoreactivity and granules showing only AVP-like immunoreactivity. The AVP-like immunoreactivity observed in the PON and the neurohypophysis is considered due to arginine vasotocin.
