Paired pulse stimulation has commonly been employed to investigate changes in excitability in epileptic hippocampal tissue employing the in vitro slice preparation. We used paired pulse stimulation in the intact temporal lobe of patients with temporal lobe seizures to compare the excitability of pathways in the epileptogenic hippocampus (located in the(More)
Previous studies have shown morphological differences in the hippocampal formation of seizure-sensitive gerbils as compared to seizure-resistant gerbils. To determine the significance of these differences, lesions were made of hippocampal afferents and efferents. Seizure-sensitive gerbils with bilateral knife cuts of the perforant path, including those with(More)
Cadmium and Zinc levels were determined in 100 patients of Essential hypertension by Atomic Absorption Spectrophotometer. It was shown that the mean levels of Serum cadmium were 43.34% +/- 6.5% higher and zinc were 28.42% +/- 5.4% lower in hypertensive when compared with normotensive controls. A statistically significant relationship between the height of(More)
The aim of the present study was to investigate the influence of reduced left anterior descending (LAD) coronary arterial blood flow on the size of the perfused coronary capillary surface area (CCSA) in dogs. The transcoronary hydrolysis (v) of the specific ACE substrate, [3H]benzoyl-Phe-Ala-Pro, was estimated and the parameter Amax/Km (proportional to the(More)
