[INFLUENCE OF SAUSSUREA CONTROVERSA AND FILLIPENDULA ULMARIA EXTRACTS ON IMMUNOLOGICAL REACTIVITY OF RATS WITH EXPERIMENTAL OSTEOMYELITIS.]

The influence of Saussurea controversa DC and Fillipendula ulmaria (L.) Maxim extracts on the immunological reactivity of rats with experimental osteomyelitis has been studied. The application of these extracts on the background of antibiotic therapy normalized the immunological reactivity indices: (i) reduced the levels of total immunoglobulins, IgM and IgG and (ii) increased the percentage of active neutrophils and their absorption capacity, as well as the percentage of completion of phagocytosis. The treatment with plant extracts reduced the acute inflammatory reaction and increased the total number of megakaryocites as compared to those upon antibiotic therapy.

[CHRONOBIOLOGICAL ACTIVITY OF AQUEOUS EXTRACTS OF THE ABOVE-GROUND PART OF AGRIMONIA PILOSA L. IN RATS.]

It is established that lithium is accumulated in the above-ground part of agrimony (Agrimoniapilosa L.), the aqueous extract of which exhibits lithium-specific chronobiological activity in rats. The chronobiological study was carried out during the winter solstice on 40 adult male rats divided into three groups: control (intact animals treated with purified water and the extract purified from lithium) and two test groups. Animals in the test groups were administered the aqueous extract of A. pilosa in the morning (8.00 am) and evening (19.00 pm) in amount corresponding to receiving lithium hydroxybutyrate in a dose of 10 mg/kg (p.o.). From the sixth to seventh day of experiment, without canceling this treatment, pilot testing (open field test, rectal temperature measurement) was started at 9 am and continued every 4 h over a period of 48 hours. The primary chronograms were statistically processing by analysis of variance, spectral analysis, and cosinor analysis. The quantitative determination of lithium in the above-ground part of A. pilosa L., its extract and brain of animals was carried out by flame photometry on a SOLAAR Series S spectrometer (Thermo Scientific Co., United States) equipped with a flaming atomizer operating in increased deuterium background correction emission mode. It was found that aqueous extract of the above-ground part of A. pilosa L. contained up to 8.5 ± 0.4 µg/g lithium; in the extract purified by ion-exchange chromatography, this amount was reduced to 1.4 ± 0.2 pg/g. All control animals exhibited external and internal desynchronism. Under the action of herbal extract, the daily dynamics of behavioral activity and rectal temperature in animals acquired a rhythmic character and became consistent with the external day-night cycle.

Evaluation of hepatoprotective activity of water-soluble polysaccharide fraction of Stellaria media L.

Therapy of rats with CCl4 hepatitis with Stellaria media L. water-soluble polysaccharide fraction in a dose of 100 mg/kg reduces serum activities of transaminases (ALT and AST), alkaline phosphatase, bilirubin, and the thymol test values. In the liver, the density of inflammatory infiltration of the organ parenchyma, total count of necrotic hepatocytes, fatty and protein degeneration are reducing. Hence, water-soluble polysaccharide fraction, isolated from the terrestrial part of Stellaria media L., is characterized by hepatoprotective activity.

[Effect of Rhaponticum carthamoides extract in combination with dosed physical load on hemorheological parameters of rats with myocardial infarction].

The administration of the extract from Rhaponticum carthamoides (150 mg/kg, p.o., for 10 days) in combination with dosed low-power exercise in rats with experimental myocardial infarction led to an improvement of hemorheological indices, which was manifested by a decrease in the whole blood viscosity, aggregation of erythrocytes, and increase in erythrocyte deformability. In particular, the extract from R. carthamoides contributed to an increase in the hematocrit/blood viscosity, which was indicative of an improvement of the blood overall oxygen transport capacity. In addition, administration of the extract in combination with dosed exercise favored normalization of the lactate and pyruvate concentrations in blood of rats with myocardial infarction.

[Main pharmacokinetic parameters of p-tyrosol after intravenous injection in rats. Part III: Distribution of p-tyrosol in rat].

Distribution of p-tyrosol in organism was studied in rats after a single intravenous administration in a dose of 200 mg/kg. It was shown that p-tyrosol rapidly penetrates into well perfused organs (brain, heart, kidneys). The maximum concentration ofp-tyrosol in these organs was determined in 1 minute after administration, and the mean distribution constant was within 0.8-1.11. The albumin bound fraction ofp-tyrozol amounted to 0.26-0.30.

Hemorheological effects of ortho-isobornyl phenol derivative under conditions of brain ischemia in rats.

Hemorheological activity of 4-methyl-2,6-di-isobornyl phenol, a new o-isobornyl phenol derivative, was studied under conditions of experimental prolonged partial cerebral ischemia. Brain ischemia is associated with hemorheological disorders which can be characterized as blood hyperviscosity syndrome: increased viscosity of the whole blood (within a wide range of shear rates), plasma viscosity, fibrinogen content in blood plasma, and platelet aggregation; deterioration of platelet deformability and reduced availability of oxygen for tissues. A course (5 days) of intragastric 4-methyl-2,6-di-isobornyl phenol (100 mg/kg) prevented the development of blood hyperviscosity syndrome by modulating blood macrorheology (reduction of plasma viscosity and fibrinogen content) and microrheology (reduction of erythrocyte aggregation and improvement of their deformability).

[Antioxidant and cardioprotective effects of N-tyrosol in myocardial ischemia with reperfusion in rats].

We demonstrated in experiments on rats with left coronary artery occlusion that intravenous administration of 20 mg/kg n-tyrosol during ischemia limited manifestations of oxidative stress in myocardial tissue during early post reperfusion period: content of diene and triene conjugates lowered 16 and 20%, respectively. This was associated with higher preservation of cardiomyocytes and reduction of the infarction zone.

[Neuroprotective effects of dibornol and mechanism of its action in rats with cerebral ischemia].

Neuroprotective activity of the new sterically hindered phenolic antioxidant 4-methyl-2,6-diisobornylphenol (dibornol) in rats with total transient cerebral ischemia was investigated. Dibornol decreased mortality of rats and the number of animals with severe neurological deficit; moreover, it accelerated restoration of neurological status in the survived rats. Neuroprotective activity of dibornol is based on its ability to diminish lipid peroxidation in ischemic brain, suppress cerebral tissue hypoxia and protect functional activity of endothelium. Improved oxygen delivery was a consequence of reduced hyperviscosity syndrome (enhanced deformability of erythrocytes and their decreased aggregation).

Antithrombogenic and antiplatelet activity of optho-isobornyl phenol derivative.

We studied antithrombogenic and antiplatelet properties of 4-methyl-2,6-diisobornyl phenol, a new promising compound belonging to ortho-isobornyl phenol derivatives, under conditions of intravascular thrombosis and acute cerebral ischemia. It was found that 4-methyl-2,6-diisobornyl phenol prevents intravascular thrombus formation by reducing platelet aggregation and improving antiplatelet activity of the vascular wall.

Effect of Rhaponticum carthamoides extract on structural and metabolic parameters of erythrocytes in rats with cerebral ischemia.

Cerebral ischemia in rats was accompanied by an increase in erythrocyte degradation, which results from changes in lipid composition of their membranes. The content of lipids and phospholipid fraction (phosphatidylcholine, sphingomyelin, and phosphatidylserine) decreased, while the relative content of lysophospholipids increased in erythrocyte membranes. The course of treatment with Rhaponticum carthamoides extract (150 mg/kg perorally, 5 days) contributed to an increase in the contents of total lipids and phospholipids (primarily of sphingomyelin and phosphatidylserine) and decrease in the ratio of lysophospholipids in the erythrocyte membrane of rats with cerebral ischemia. Morphological characteristics of erythrocytes returned to normal, which manifested in an increase in the number of discocytes and decrease in the count of degenerated cells.

[Therapeutic effect of p-tyrosol on myocardial electric instability induced by coronary occlusion].

In experiments on rats with left coronary artery occlusion, p-tyrosol (20 mg/kg, intravenously) showed the ability to decrease myocardial electric instability in phase 1b of ventricular arrhythmias: a fraction of rats without arrhythmia was increased by 36%, and the mean value of ventricular arrhythmia index exhibited a 3-fold decrease.

Hepatoprotective and antioxidant activity of meadowsweet extract during experimental toxic hepatitis.

The extract of meadowsweet aerial parts exhibits hepatoprotective and antioxidant activity during experimental toxic CCl(4) hepatitis. This extract improved liver function.

[Effect of Rhaponticum carthamoides extract on hemorheological properties of blood in rats with arterial hypertension]. / Vliianie ekstrakta levzei salorovidnoi na reoloigheskie svoistva krovi u krys s arterial'noi gipertenzei.

The hemorheological activity of a dry extract from Rhaponticum (Leuzea) carthamoides (Willd.) Iljin. was studied in spontaneously hypertensive rats (SHRs). A 14-day treatment of the test rats with a daily dose of 150 mg/kg improved the rheological characteristics, as manifested by a reduced viscosity of the whole blood and plasma, increased spontaneous erythrocyte aggregation and fibrinogen concentration, and increased erythrocyte deformability and electrophoretic mobility against the untreated control level.

Ischemia-induced changes in synaptoarchitectonics of brain cortex and their correction with ascovertin and Leuzea extract.

Peroral administration of 70 mg/kg ascovertin and 150 mg/kg Leuzea extract to rats with cerebral ischemia for 5 days prevented destructive changes and decrease in the density of synapses in the cerebral cortex. These preparations activated compensatory and reparative mechanisms underlying plasticity of the synaptic pool, which was realized through hypertrophy and destruction of synaptic contacts. Ascovertin possessed more pronounced cerebroprotective activity than Leuzea extract.
