The effect of piracetam on the local cortical cerebral blood flow in cats.
The effect of piracetam on the local cortical cerebral blood flow (CBF) and oxygen balance in the brain was studied on cats anesthetized with ether-chloralose and most probably the increase in CBF does not participate in the mechanism of the protective action of Piracetam in hypoxia.
Effect of piracetam in models of experimental inflammation.
Piracetam restricts the development of the exudative and proliferative phases of the inflammatory process and the degree of this reduction in the models used is similar to that observed after treatment with known antiinflammatory drugs.
Chemical Composition and Energy Nutritional Value of the Meat of Guinea Fowls (Numidameleagris), Fattened to different Ages
The aim of the study was to investigate the chemical composition and energy content of the meat of young guinea-fowls, with different duration of the fattening period, raised in a free-range,
Anti-hypoxic effect of centrally and systemically administered prostacyclin (PGI2).
Prostacyclin (PGI2) induced a dose-dependent prolongation of survival time of mice subjected to hypoxic and anoxic hypoxia, when administered either intracerebroventricularly (i.c.v., 0.001-10
Anti-hypoxic effect of piracetam and its interaction with prostacyclin.
Piracetam showed anti-hypoxic effect, which was greater than that of cinnarizine and similar to that of vinpocetine, and potentiated the effect of PGI2 shifting the anti- Hypoxic dose-response curve of P GI2 to the left.
Effect of nicergoline on learning and memory.
Nicergoline demonstrates well-expressed anti-amnestic effect manifested by reducing the amnestic effect of maximal electroshock, scopolamine or paradoxical sleep deprivation, its effect being equal to or more pronounced than piracetam, meclofenoxate, pyritinol, deanol and phenazepam.
Anti-hypoxic effect of prostacyclin.
The anti-hypoxic effect of prostacyclin (PGI2) was studied using the following methods: hypoventilation hypoxia and hypovolemic oligemia in cats and hypobaric hypoxia and complete ischemia by
Cerebroprotective effect of flunarizine.
The EEG frequency-amplitude analysis during asphyxic hypoxia showed a significant decrease of the slow-waves amplitudes of delta and theta range, and an increase of the fast-waves amplification of beta-2 range, changes indicating protective action.
Study on the anti-hypoxic effect of some drugs used in the pharmacotherapy of cerebrovascular disease.
The most pronounced anti-hypoxic effect was shown primarily with the metabolic acting drugs, such as orotic acid, centrophenoxine, piracetam and pentobarbital, followed by the preparations with combined metabolic and vasoactive properties (vincamine and vinpocetine).
Investigation of the effect of Tribulus terrestris extract on some characteristics of the reproductive capacity of guinea fowl
The effect of Bulgarian product Vemoherb-T (dry extract of Tribulus terrestris) on some characteristics of the reproductive capacity of Guinea fowl was studied and found a higher laying intensity, egg morphology and fertility, the weight of testes and ovaries were controlled.
