Possible migration and histopathological analysis of injections of polymethylmethacrylate in wistar rats.

Objective. To evaluate the possible migration of polymethylmethacrylate after injections in various corporal compartments of Wistar rats. Methods.

Behavioural and electroencephalographic effects of systemic injections of 8-OH-DPAT in the pigeon (Columba livia).

The effects of systemic injections of the 5HT(1A) receptor agonist 8-OH-DPAT on the spontaneous ingestive, maintenance, locomotor and sleep-like behaviours, and the sleep/waking-related hippocampal electrographic activity were investigated in pigeons. 8-OH-DPAT (0.06, 0.
