| We evaluated the effects of the neuroleptic agent propericiazine on animal models of anxiety and memory. Adult male Wistar rats (250 to 350 g) received intraperitoneal injections of propericiazine (0.05, 0.075 and 0.1 mg/kg), diazepam (1 mg/kg), saline, or diazepam vehicle (20% propylene glycol and 80% saline) 30 min prior to the experimental procedure. Animals (10-15 for each task) were tested for step-down inhibitory avoidance (0.3-mA footshock) and habituation to an open-field for memory assessment, and submitted to the elevated plus-maze to evaluate the effects of propericiazine in a model of anxiety. Animals treated with 0.075 mg/kg propericiazine showed a reduction in anxiety measures (P<0.05) similar to that observed in those treated with... |

| Sepsis and its complications are the leading causes of mortality in intensive care units, accounting for 10-50% of deaths. Intensive care unit survivors present long-term cognitive impairment, including alterations in memory, attention, concentration, and/or global loss of cognitive function. In the present study, we investigated behavioral alterations in sepsis-surviving rats. One hundred and ten male Wistar rats (3-4 months, 250-300 g) were submitted to cecal ligation and puncture (CLP), and 44 were submitted to sham operation. Forty-four rats (40%) survived after CLP, and all sham-operated animals survived and were used as control. Twenty animals of each group were used in the object recognition task (10 in short-term memory and 10 in long-term memory),... |
