M. Miele et M. Fillenz, CHANGES IN EXTRACELLULAR BRAIN ASCORBATE IN RAT STRIATUM IN RESPONSE TO ADMINISTRATION OF NONVOLATILE ANESTHETIC AGENTS, British Journal of Anaesthesia, 78(5), 1997, pp. 588-590
We used constant potential in vivo voltammetry to measure changes in s
triatal ascorbate in the rat in response to i.p. administration of sev
eral nonvolatile anaesthetics. Propofol and pentobarbitone, which enha
nce GABA-mediated neuronal inhibitions, decreased ascorbate current to
27.0 (SEM 7.4) % and 46 (6) % of control, respectively. Chloral hydra
te, diazepam alone or with ketamine, and fentanyl-fluanisone with mida
zolam produced no changes in ascorbate current.
