Absence of coexistence between NADPH-diaphorase and antidiuretic hormone in the hypothalamus of two galliforms: Japanese quail (Coturnix japonica) and chicken (Gallus domesticus).
Based on previous studies demonstrating coexistence of NADPH-diaphorase (ND) and vasopressin (VP) in the rat hypothalamus. ND histochemistry and vasotocin (VT) immunocytochemistry have been combined in order to study the distribution of both markers in the hypothalamus of the Japanese quail (Coturnix japonica) and chicken (Gallus domesticus). No coexistence was found, however, close anatomical relationships between ND-positive and VT-immunoreactive elements were observed in specific preoptic and hypothalamic locations. These findings indicate interspecies differences in the expression of ND and the antidiuretic hormone with functional implications in osmoregulation.
