[Innervation of the renal artery in rabbits]. / Inervácia arteria renalis u králika.

An ultrastructural study of the innervation of the renal artery in the rabbit is presented. Fixation in KMnO4 was used for the identification of adrenergic nerve endings. This technique ensures the optimal preservation of small granular vesicles which are characteristic for adrenergic axons. All the axon terminals observed at electron microscopic level contained synaptic vesicles of this type. The bundles of adrenergic nerve fibers were located in the adventitia, especially on the border between the adventitia and media.

[Comparison of the hemodynamic properties of a reversed and an in situ bypass in an experiment]. / Porovnanie hemodynamických vlastností obráteného a in situ bypassu v experimente.

The authors compared under standard experimental conditions the flow through a reversed venous segment and a non-reversed segment after destruction of the valves by means of a valvulotome. They did not confirm the theoretical assumptions of more favourable haemodynamic properties of a venous bypass in situ.
