Changes in systemic and regional hemodynamic during sound-induced convulsions were measured with microsphere technique in genetically epilepsy-prone rats of Krushinsky-Molodkina (KM-rats) strain. Blood pressure increased from 103 till 178 mm Hg and cardiac index rose from 27.3 till 49.3 ml/min/100 g b. w. during convulsions. Blood flow was increased in the… (More)
There is a permanent interest in medicinal plants around the world: about 40% of all remedies are of plant origin, while their proportion in drugs for the therapy of cardiovascular diseases amounts to 80~ One of the main reasons for this success of medicinals of natural origin is the absence of some detrimental side effects frequently inherent in synthetic… (More)
1-min forceful immersion in water increased mean arterial pressure by 24% in Ondatra, decreased their heart rate by 71% and cardiac output by 36% Respective figures in Wistar rats were as follows: 19%, 62%, and 46% decrease. By the 50th sec of immersion cerebral blood flow increased 13-fold in Ondatra and 6-fold in Wistar rats.
A technology of obtaining biologically active substances from Ambrosia artemisiifolia has been analyzed and experimentally proved taking into account the vegetation stage. Use of the above-ground parts of the plant collected in the stage of budding as the starting raw material solves two important problems by (i) eliminating the source of the allergenic… (More)
In acute experiments on anesthetized cats with cerebral ischemia in conditions of autohemoperfusion of cerebral and peripheral vessels with a stable volume of blood we found that lithium oxybutirate and new GABA derivatives: LOS 1-84 and LOS 5-79 affect the cerebral blood flow and metabolism in the brain. Prophylactic intravenous injection of lithium… (More)
We demonstrated a dose-dependent inhibitory effect of novel imidazobenzoimidazole derivatives RU-353 and RU-563 on cerebral blood flow and systemic blood pressure in narcotized rats. The effects of RU-353 increased, while the effect of RU-563 decreased with increasing the dose.
Modem medicine uses flavonoid compounds for treating many diseases, which exhibit a wide spectrum of biological action. One of the representatives of this class is diosmin (5,7,3'-trihydroxy-4'-methoxyflavone rhamnoglucoside); it is the major active principle of a number of drugs produced in France (Daflone, Vendetrex, etc.) for treatment of phlebitis,… (More)
The effects of yohimbine and idazoxane (0.5 and 5 mg/kg, intravenously) on the systemic and regional hemodynamics were studied in conscious Wistar rats by the microsphere technique. The both drugs induced an elevation of the arterial blood pressure and the heart rate. The administration of yohimbine and idazoxane in a dose of 0.5 mg/kg produced a more… (More)
In anesthetized cats, comparative characteristics of hemodynamics and biochemical indications of postischemic period in respect to autohemoperfusion with stable blood volume and perfusion pressure, were determined. Cerebral ischemia was caused by the 15-min stop of the perfusing pump or flowmeter and a decrease of systemic arterial blood pressure to 40 ml… (More)
Single intravenous injection of antidepressant tetrindol (1 and 10 mg/kg), a reversible monoamine oxidase A inhibitor, dose-dependently decreased heart rate and mean arterial pressure (in a concentration of 10 mg/kg) in alert NMRI mice and Sprague-Dawley rats. Nitric oxide synthase blockade with L-NAME attenuated tetrindol-induced bradycardia in rats and… (More)
