The long-term effects of early postnatal exposure to aluminium on acetyl choline esterase (AChE) activity and on biogenic amines were studied in different brain regions. The subjects were eight days old male Wistar rat pups. They were grouped into normal control and aluminium exposed groups. For aluminium exposure, the pups were gastric intubated with(More)
The present study examined the effects of ibotenic acid lesions of the ventral subiculum (SUB) on the ability of rats to memorize a rewarded alternation test in a T-maze. Results indicated that rats with ibotenic acid lesions (IL) of the ventral subiculum were impaired in postoperative acquisition of the spatial discrimination task, making more errors than(More)
Aluminum chloride (AlCl(3); 4 mg/kg) was injected into the cerebrospinal fluid of adult rats as a one time dose. Rapid Golgi stained sections of hippocampus were examined for detailed histology of neurons in CA1, CA2, and CA3 areas. The axonal length and number of dendritic branches were seen reduced 30 days later in aluminum (Al)-injected group when(More)
The present study demonstrates the effect of ibotenic acid lesioning of ventral subiculum on the theta activity of CA1 area of hippocampus and the entorhinal cortex during REM sleep. Ibotenic acid lesioning of ventral subiculum, has increased the absolute power with no noticeable change in the relative power of theta of the CA1 area. In contrast, it has(More)
Golgi examination of neurons of self-stimulation areas of the lateral hypothalamus and substantia nigra-ventral tegmental areas of adult Wistar rats that had experienced self-stimulation for 10 days revealed a significantly higher number of dendritic branching points in the two self-stimulation areas, and also in the hippocampus (CA3 pyramidal neurons) than(More)
We have evaluated potential neuroprotection offered by (-)-deprenyl on degenerating motor neurons of the spinal cord when subjected to transient ischemia. Thirty-six healthy adult male Wistar rats were trained for a motor function test in a staircase maze and randomly but equally (n = 6) grouped into normal control, sham control, ischemia (IS), IS rats(More)
The spectrum of vascular lesions developing in breast or chest wall skin following lumpectomy or mastectomy and radiation is wide and ranges from atypical vascular lesions with a benign clinical behaviour to frankly malignant, angiosarcoma ranging histologically from well to poorly differentiated variety. Postmastectomy-postirradiation atypical vascular(More)
In conscious Wistar rats neuromuscularly paralysed by gallamine, operantly conditioned reduction of heart rate was achieved under both negative and positive reinforcement schedules using the tail shock avoidance or the rewarding brain-stimulations in 20-min test sessions. The primary aim was to assess whether it would be possible to achieve operant(More)
