ABSTRACT
OBJECTIVE: The relevance of the problem considered in the present communication arises to-day from the widespread prevalence of osteoporosis (OP), the rather low effectiveness of the methods currently available for the treatment of this condition, and iatrogenic effects of its medication therapy. The great diversity of phytotherapeutic modalities of traditional medicine are is only poorly supported by the results of the scientific studies results; moreover, most of them are coming from the foreign literature publications. AIM: The objective of the present study was to evaluate the influence of the phytotherapeutic preparation (Phytocost) having cyclodextrin in its composition on the restoration of the cartilaginous and bony tissues based on the experimental research with the use of the OP experimental model. MATERIAL AND METHODS: The experimental studies were performed on 5 month-old Balb/c mice used as the prednisolone-induced osteoporosis model. The animals were divided into four study groups according to the daily doses administered to them: 0.005; 0.05; 0.5 and 5.0 mg/mouse during 30 days and 3 control groups: intact, 14 and 30 days after prednisolone administration, naïve mice. RESULTS: The study has demonstrated the dose-dependent protective effect of cyclodextrin-containing Phytocost. The most pronounced effect in the form of reduction of osteoblast number and the increase in the number of osteocytes was obtained at a Phytocost dose of 0.5 mg/mouse. No undesirable adverse reactions were documented during the study. CONCLUSION: The domestically produced Phytocost composition differs from its foreign analogues in that it contains a significantly greater number of constituent components because the ultimate goal of the study was to create a medication acting on all currently known mechanisms of OP pathogenesis, whereas our Chinese colleagues proceed from the ancient knowledge gained by traditional medicine that it is sometimes difficult to understand and explain in the light of the modern concepts. All the plants used as raw materials for Phytocost production grow at the territory of the Russian Federation which provides the possibilities for the efficient import substitution of the components necessary for the manufacture of the preparation in question.

Presents a new import-substituting the composition of the powder mixture 60 medicinal plants and dead bees. In prednisolonbuy models of osteoporosis have shown dose-dependent regenerative effects bone and cartilage of the hip joints of mice. Unwanted side effects when taking composition was observed. It is assumed the possibility of effective application of the composition as a complementary treatment for osteoporosis.

The study was performed on 30 male rats of Wistar line (weight 330-360 g, age 3.5 months).In an experimental model of damage to the femur bone in the hip joint studied the effect of low frequency electrical stimulation of the damaged area on the rate of regeneration of bone. The animals were divided into two groups. Control (15 rats) and experienced (15 rats). In the experimental animals underwent stimulation of the injury site for 5 min daily for 7 days, 14 days and 21 days. Stimulation was carried out using a device "Osteon-1" generating a mixed signal of two voltage pulse of varying duty cycle, one of which is modulated to a higher frequency. Signals were not synchronized with respect to each other, unipolar with varying frequencies and amplitudes. The obtained results show the effectiveness of the electrical stimulation currents of low frequency in the restoration of bone tissue after damage. Morphological studies showed that electrical stimulation to accelerate the regeneration of damaged bone at all stages of the study (7, 14, 21 day), causes a more pronounced integration of newly formed bone with the old intact bone and promote the formation of more powerful periosteal calluses in comparison with the control.
