Anti-Inflammatory and Analgesic Activities of the Complex of Flavonoids from Lychnis chalcedonica L.

Anti-inflammatory and analgesic activities of the complex of flavonoids from Lychnis chalcedonica L. were studied in the models of acute aseptic inflammation induced by carrageenan, histamine, and serotonin and acetic acid-induced painful chemical stimulation. It is demonstrated that course treatment with flavonoids derived from Lychnis chalcedonica L. produced a stable pharmacological effect comparable with that of the reference anti-inflammatory drug diclofenac.

Antitoxic Activity of Extract from Salix Viminalis Leaves under Conditions of 5-Fluorouracil Treatment.

Injection of 5-fluorouracil to animals caused a pronounced toxic effect. Therapeutic and preventive treatment with Salix viminalis leaf extract significantly reduced the negative effects of the antitumor drug: promoted recovery of the bone marrow, peripheral blood, and visceral parameters and prevented ulceration. Combined use of the cytostatic and Salix viminalis extract increased the efficiency of antitumor therapy.

Analgesic activity of diterpene alkaloids from Aconitum baikalensis.

We compared analgesic activities of individual alkaloids extracted from Baikal aconite (Aconitum baikalensis): napelline, hypaconitine, songorine, mesaconitine, 12-epinapelline N-oxide. The detected analgesic activity was comparable to that of sodium metamizole. The mechanisms of analgesia were different in diterpene alkaloids of different structure. The antinociceptive effect of atisine alkaloids (12-epinapelline N-oxide, songorine) was naloxonedependent and realized via opioid receptor modulation.

Anti-inflammatory activity of diterpene alkaloids from Aconitum baikalense.

We compared anti-inflammatory activity of individual diterpene alkaloids isolated from Aconitum baikalense (napelline, songorine, hypaconitine, mesaconitine, 12-epinapelline N-oxide) under conditions of acute inflammation of different genesis. The tested substances showed high antiexudative activity comparable with that of sodium diclofenac. Unlike nonsteroidal anti-inflammatory drugs, diterpene alkaloids exerted no ulcerogenic effect.

[Evaluation of anti-inflammatory activity of extracts from Siberian plants].

Experimental investigations have shown that water-alcohol extracts from plants containing alkaloids (Aconitum baikalense, Aconitum septentrionale, Delphinium elatum L., Conium maculatum) and salicylic acid (Filipendula ulmaria, Salix viminalis, Fragaria vesca, Rubus idaeus) inhibited the development of main symptoms of inflammation, viz. exudation, pain, fever, to the same extent as non-steroidal anti-inflammatory agents. The substances studied in this work may be used to develop new efficient pharmacological preparations for the treatment of different inflammatory conditions associated with severe pain syndrome.

[Mechanisms of antistressor activity of Inula helenium preparations]. / Nekotorye mekhanizmy stress-protektornogo deistviia preparatov iz Inula helenium.

The antistressor and antioxidant properties of preparations from the underground part of elfwort (Inula helenium) were studied on a model of acute stress in mice. The preparations produced a protective effect with respect to internal organs, blood, carbohydrate metabolism, and lipid peroxidation process.

[The principles for creating drug preparations of natural origin that stimulate hematopoiesis]. / Printsipy sozdaniia lekarstvennykh preparatov--stimuliatorov krovetvoreniia prirodnogo proiskhozhdeniia.

The paper outlines the principles in designing hemostimulators by using glycosamineglycans. Hemostimulating properties of the tested agents is likely to be primarily due to the presence of D-glucuronic acid in their structure. The homotypic mechanisms are largely responsible for all agents' effect in stimulating hemopoiesis. Thus, they all virtually activate the function of the hemopoiesis-inducing microenvironment. In addition, they directly or indirectly stimulate the processes of proliferation and differentiation of precursor cells of erythro- and granulomonocytopoiesis.

[Significance of sympathetic-adrenal structures in hematopoiesis regulation in cytostatic myelodepression]. / Znachenie simpatiko-adrenalovykh struktur reguliatsii gemopoéza pri tsitostaticheskoi mielodepressii.

The role of the sympathetic nervous system in the regulation of bone marrow hematopoiesis has been studied on mice CBA after administration of 5-fluorouracil (114 mg/kg). The double injection (3-5 minutes before and 5 hours after 5 + U) of ganglionic blocking drug (pentamine, 6 mg/kg), alpha-adrenergic (dihydroergotamine, 3.9 mg/kg) or beta-adrenergic antagonists (propranolol, 5 mg/kg) inhibited the post-cytostatic reparation of erythro- and granulocytopoiesis. Besides, addition of the same neurotropic antagonists and 5-FU (10(-7) M) to bone marrow culture led to 1.5-3 fold decrease of cell content in comparison with alone cytostatic after 24 hours incubation. On the contrary injection of neuroblocking agents (twice in 5 hours) on day 3 after 5-FU administration elevated the total count of erythroid cells immature and mature granulocytic leukocytes in bone marrow and polymorphonuclear leukocytes in blood. Thus, the unequal role of the sympathetic nervous system in the regulation of hematopoiesis at the different periods after high dose of 5-FU administration has been demonstrated.
