The posterolateral tunnel on the superior surface of the first cervical (atlas) vertebra is of normal occurrence in monkeys and other lower animals, but its presence in the form of a tunnel-like canal, for the passage of the third part of the vertebral artery over the posterior arch of the human atlas vertebra is not reported. The aim of the present study(More)
Groups of rats were administered thallous acetate 5 mg/kg or acetyl-homocysteine-thiolactone (citiolone) 8 mg/kg body weight, i.p. daily for 6 days. A third group of rats received the same doses of both thallium and citiolone for 6 days. Total sulfhydryl radicals and glutathione content were estimated in the cerebral hemisphere, cerebellum and brain stem.(More)
— This paper describes the modeling of distance relay using Matlab/Simulink package. SimPowerSystem toolbox was used for detailed modeling of distance relay, transmission line and fault simulation. Inside the modeling, single line to ground (SLG) fault was choose to be the fault type and Mho type distance characteristic was choose to be as the protection(More)
DDVP is an organophosphate pesticide whose neurotoxicity, in the form of cholinesterase inhbition, is well-known. Rats, weighing 200-225 g were given intraperitoneal injections of 3 mg/kg. DDVP daily for 10 days. Following perfusion-fixation, ultrathin sections of the cerebellum and spinal cord were examined with an electron microscope. A large number of(More)
The levels of dopamine, noradrenaline and 5-hydroxytryptamine were estimated in the hypothalamus and limbic areas, corpus striatum, cerebellum and the brain-stem of rats administered thallous acetate (5 mg/kg i.p.) daily for 7 days. Significant decreases in the concentration of dopamine occurred in the hypothalamus, limbic areas and corpus striatum.(More)
The caudal part of the fourth ventricle in adult rhesus monkeys, of both sexes, revealed the area postrema (AP) to be composed of bilateral spindle-shaped elevations located ventromedial to the gracile tubercles. Supraependymal (SE) elements, comprised of SE cells and/or fibre processes could be seen near the medial margin of a narrow oligociliated strip(More)
Dichlorvos (O,O-dimethyl-2:2-dichlorovinyl phosphate) was administered IP (3 mg/kg) daily for 10 days to a group of albino rats. Open field behavior was significantly depressed below the mean of the control group. On day 7, ambulation was reduced to 24% of the mean but recovered to 60% on day 10. Similarly, rearing response was decreased on day 7 and showed(More)
Rats were given thallium acetate (5 mg elemental thallium/kg body weight) intra-peritoneally daily for 7 days. The brain was fixed by perfusion-fixation and small pieces of the cerebellum were processed for electron microscopy. Variegated mitochondrial profiles, increased incidence of electron--dense bodies and proliferation of Golgi zones were observed in(More)
The central auditory toxicity of sisomicin was studied in guineapigs administered sisomicin (135 mg/kg body weight) sc for 10 days. Total lipids, phospholipids and cholesterol were estimated in the pons, inferior colliculus, medial geniculate body and auditory cortex. While the total lipids were increased in a non-preferential manner in all the regions(More)
