Stainless steel cannulae were implanted stereotaxically in the third ventricle of male albino rats. The rats were fed with natural food pellets and water ad lib. After seven days of cannulation, daily body weight, food intake and water intake were recorded for the first five days, which was considered the preinjection control. Then increased and repetitive(More)
The effect of acute IIIrd ventricle injection of GABA, muscimol, and picrotoxin on the activity of monoamine oxidase (MAO) has been investigated in serum and a few hypothalamic nuclei of the rat brain using biochemical, histochemical, and cytophotometric techniques. Biochemical estimation demonstrated a significant reduction in MAO enzyme activity after(More)
The effects of intracerebroventricular injection of gamma-Aminobutyric acid, muscimol, or picrotoxin have been studied on butyrylcholinesterase (BuChE) activities in the serum and several hypothalamic nuclei using biochemical, histochemical, and cytophotometric techniques, respectively. The blood samples were withdrawn from indwelling catheters in jugular(More)
Effects of intraventricular injections of GABA, and a GABA agonist, muscimol and an antagonist, picrotoxin on succinate dehydrogenase (SDH) enzyme activity in plasma and a few hypothalamic nuclei of brain of rats have been investigated using biochemical, histochemical and cytophotometric techniques. Results show that SDH decreased by GABA and muscimol(More)
