[Electroencephalographic study of the eel (author's transl)].

1 This paper describes a method for electroencephalographic recording from unanesthetized and unraistrained european eels (Anguilla anguilla L.). 2 EEG's records from the cerebellum, tectum opticum, telencephalon and olfactory bulb of the eel are compared with other fish previously studied by other authors. 3 Averaged evoked visual potentials from the telencephalon, tectum opticum and cerebellum are presented. 4 This study provides a reference point for future research on fish vigilance depth and EEG changes associated with modified environmental factors.

Intracerebroventricular injection of arginine vasotocin induces elevation of blood pressure in anesthetized trout.

The present investigation assessed the ability of the neurohypophysial nonapeptide arginine vasotocin (AVT) to centrally regulate the cardiovascular activity in fish. Intracerebroventricular (ICV) injection of AVT (0.4 to 50 ng/kg b.wt.) in anesthetized trout resulted in a dose-related increase in blood pressure (BP) without any consistent changes in heart rate. For doses of AVT ranging from 2 to 50 ng/kg b.wt., BP remained elevated during at least 25 min after ICV injection. Systemic (intraarterial) administration of the same doses of AVT appeared to be less efficient than ICV injection, except for the highest dose (50 ng/kg) which evoked a similar rise in BP as that observed after ICV administration. In contrast to AVT, a high concentration of neuropeptide Y (10 micrograms/kg b.wt., ICV) caused only a slight increase of BP. The results suggest that AVT acts centrally to regulate BP in fish. These data, together with the widespread distribution of AVT-immunoreactive fibers and AVT binding sites in the brain, support the notion that, in fish, AVT may play neuromodulator and/or neurotransmitter functions.

[Evolution of motor nerve conduction and Hoffmann reflex in 100 patients with chronic renal failure treated by periodic hemodialysis (author's transl)].

The study of motor nerve conduction (MNC) and H. reflex was carried out on 100 chronic uraemic patients, fifty-four males and fourty-six females, treated by periodic hemodialysis. The MNCV is more frequently normal in females than in males. Periodic hemodialysis improves MNCV but sometimes uraemic neuropathy appears with hemodialysis. The MNCV is oftener improved than H. reflex latency. Results are neither significantly improved by a greater number of hemodialysis seances nor in function of the different dialyzers. Any kidney activity does not modify the nerve conduction.
