The aim of the work was to study the effect of fractions from Saussurea controversa and Мeadowsweet extracts on hemopoiesis and regeneration of bone tissue, which are the main target indicators in experimental osteomyelitis.Materials and methods. In the experiment we used butanol, water and element-organic fractions from the Saussurea controversa extract as well as ethyl acetate, butanol and water fractions from the Мeadowsweet extract, obtained by liquid extraction of the extracts from corresponding plants with the help of organic solvents. After modeling osteomyelitis of the right femur in rats and course treatment for 28 days, the state of bone marrow hemopoiesis was evaluated and morphological examination of the affected limb was performed.Results. The butanol fraction (at a dose of 10 mg/kg) containing flavonol glycosides, the water fraction (at a dose of 80 mg/kg) containing polysaccharides in its composition and the element-organic fraction (at a dose of 10 mg/kg) represented by organic calcium showed the highest osteogenic activity in the Saussurea controversa extract. The water fraction from the Meadowsweet extract (at a dose of 50 mg/kg) demonstrated pronounced hemopoietic activity due to stimulating erythro-, granulo- and lymphopoiesis in the bone marrow of rats with experimental osteomyelitis.

Aim. The influence of dry extracts of Saussurea controversa DC. and Filipendula ulmaria (L.) Maxim. in experimental osteomyelitis with the use of сefazolin in rats.Materials and methods. After a course of therapy extracts at a dose of 100 mg/kg on the background of antibiotic therapy observed localization of the inflammatory process, whereas animals receiving only Cefazolin becomes diffuse inflammation. In the conditions of complex therapy the level of diene conjugates significantly reduces in the serum and the level of TBA-active products, total lipids and lysophosphatidylcholine reduces in the muscle tissue of the affected area. In the application of extracts of S. controversa returns to normal level of diacylglycerides and phosphatidylcholine, and the application of the extract of F. ulmaria – free cholesterol in comparison with the group of animals treated only with сefazolin.Results. In the application of water-ethanol extract of S. controversa with simultaneous intramuscular сefazolin marked decrease in the activity of acid and alkaline phosphatase that can enhance reparative processes in the bone tissue.
