title: [Ecologic-histophysiological analysis of the neurohypophysis-metaadenohypophysis complex of the sazan female before and after spawning].
abstract: Much neurosecretory material (4.4 +/- 0.1 units) is seen in the neurohypophysis of sazan females before spawning. A1, A2, and B type terminals contain numerous neurosecretory granules, in particular, elementary granules. Synaptic vesicles are not numerous. The amount of neurosecretory material decreases during and shortly after spawning down to 3.6 +/- 0.3 units. Neurosecretory terminals have less elementary granules. The number of granulated, disintegrating, residual granules and synaptic vesicles somewhat increases. It is hypothesized that mainly peptide neurohormones are discharged from A1 and A2 terminals in the common circulation, and that both peptide neurohormones and monoamines reach glandular cells of the metaadenohypophysis in sazan females during and immediately spawning. The role played by neurohormones and monoamines in controlling the function of both the metaadenohypophysis glandular cells and visceral organs involved in the general adaptive reactions of the fish organism is discussed.
