AB  - The aim of the study was to examine the effects of chronic exercise training on seizures induced by homocysteine thiolactone (HCT) in adult rats. Rats were assigned to: sedentary control; exercise control; sedentary +HCT; exercise + HCT group. Animals in the exercise groups ran 30 min daily on a treadmill for 30 consecutive days (belt speed 20 m/min), while sedentary rats spent the same time on the treadmill (speed 0 m/min). On the 31st day, the HCT groups received HCT (8.0 mmol/kg), while the control groups received vehicle. Afterwards, convulsive behavior and EEG activity were registered. Lipid peroxidation, superoxide dismutase (SOD) and catalase (CAT) activity were ascertained in the rat hippocampus. No signs of seizures were registered in sedentary and exercise control rats. Seizure latency was increased, while number of seizure episodes and spike-and-wave discharges (SWD) in EEG were decreased in the exercise + HCT compared to the sedentary +HCT group. Seizure incidence, the severity thereof and duration of SWDs were not significantly different between these groups. Exercise partly prevented increase of lipid peroxidation and decrease of the SOD and CAT activity after HCT administration. These results indicate beneficial effects of exercise in model of HCT induced seizures in rats, what could be, at least in part, a consequence of improved antioxidant enzymes activity.

AB  - Thioacetamide (TAA) is widely used as a model of hepatic encephalopathy (HE). The aim of our study was to investigate the effects of TAA on electroencephalographic (EEG) changes in rats and to compare them with human HE. Male Wistar rats were divided into groups: (1) saline-treated group and (2) TAA-treated groups: TAA(300) (300 mg/kg), TAA(600) (600 mg/kg), and TAA(900) (900 mg/kg). Daily dose of TAA (300 mg/kg) was administered intraperitoneally once (TAA(300)), twice (TAA(600)), or thrice (TAA(900)) in subsequent days. EEG changes were recorded about 24 h after the last dose of TAA. Absolute and relative power density in alpha bands were significantly higher in TAA(300) versus control group. In TAA(300), absolute beta power density was higher and relative beta power density was lower versus control group. Absolute alpha, theta, delta, and relative theta power were significantly lower, while relative power in delta band was significantly higher in TAA(900) versus control group (p LT 0.01). In conclusion, decrease in EEG voltage with an increase in delta relative power, which correspond to the EEG manifestations of severe HE in humans, was observed in TAA(900) group. Electrical activity in TAA(300) group correlates with mild HE in humans.

AB  - Thioacetamide (TAA) exerts hepatotoxic, neurotoxic and carcinogenic effects. The aim of our study was to investigate the effects of TAA on lipid peroxidation and catalase activity in various rat brain regions. Male Wistar rats were divided into following groups: 1. control, saline-treated; 2. thioacetamide-treated groups, TAA(300) (300 mg/kg), TAA(600) (600 mg/kg) and TAA(900) (900 mg/kg). Daily dose of TAA (300 mg/kg) was administered intraperitoneally once (TAA(300)), twice (TAA(600)) and three times (TAA(900)) in consecutive days. Brain samples were collected 24 h after the last dose of TAA and malondialdehyde (MDA) level and catalase activity were determined in cortex, brainstem and hippocampus. MDA level was significantly increased while catalase activity was significantly lower in all brain regions in TAA(900) group in comparison with control group. In TAA(600) MDA level was increased in the brainstem and cortex when compared to control (p LT 0.01). The same dose of TAA(600) mg/kg induced a significant decline in catalase activity in the brainstem and cortex and an increase in its activity in the hippocampus when compared to control (p LT 0.01). In TAA(300) an increase in MDA level was evident only in the brainstem. Catalase activity was significantly higher in the cortex and hippocampus in TAA(300) group in comparison with control (p LT 0.01). Based on these results, it may be concluded that various rat brain regions have different sensitivity to TAA-induced lipid peroxidation with hippocampus being less sensitive than cerebral cortex and brainstem.
