SHULGAU, Zarina et al. Osteoprotective Properties of RNA-Containing Drug Osteochondrin S on the Model of Insufficiency of Sex Hormones in Rats. Int. J. Morphol. [online]. 2017, vol.35, n.4, pp.1233-1238. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022017000401233.

The aim of the study was to evaluate the osteoprotective properties of RNA-containing drug Osteochondrin S on rats with experimental model of osteoporosis. Osteochondrin S contains yeast RNA and RNA of connective tissue of cattle. In order to model osteoporosis in rats bilateral ovariectomy was used. Rats were divided into 3 groups: 1 - ovariectomized rats receiving Osteochondrin S; 2 - ovariectomized rats receiving saline; 3 - sham-ovariectomized rats. Rats in group 1 received Osteochondrin S, Group 2 - physiological saline three times a week for 12 weeks. Based on morphological data and on the results of densitometry, Osteochondrin S prevents a decrease in bone density, i.e. exhibits osteoprotective properties. Under the condition of lack of sex hormones in rats Osteochondrin S reduces reactive oxygen species in blood plasma and limits the degree of decrease in antioxidant capacity of blood plasma.
