ABSTRACT
Objective To investigate the effects of isoflurane (Iso) on the water-maze performances in scopolamine (Sco) treated rats.Methods Fifty-five male SD rats weighing 150-200 g were randomly divided into 8 groupsgroup I control (Con)/1 d ( n = 6); group II Iso/1 d ( n = 7);group III Sco/1 d ( n = 9);group IV Iso + Sco/1 d ( n = 9) ; group V Con/7 d ( n = 6); group VI Iso/7 d ( n = 6); group VII Sco/7 d ( n = 6) and group VIII Iso + Sco/7 d ( n = 6) . In Iso and Iso + Sco groups the animals inhaled 1.5% isoflurane 2 h per day for four consecutive days. The Morris water-maze (MWM) test was performed for 3 consecutive days starting from the first day (group I -IV ) or the 7th day (group V -VII) after the 4 day isoflurane inhalation. Scopolamine 0.8 mg.kg-1 was given ip 20 min before the beginning of the MWM test in Sco and Iso + Sco groups. Results In group I - IV , (1) the latency period and swimming distance were significantly longer in Sco and Iso + Sco group than those in Con and Iso group ( P
