The fruits of marsh cranberries due to the content of phenolic compounds, in particular proanthocyanidins, are effective in the prevention and treatment of cystitis [1].

The aim of the research was to study the anti-inflammatory properties of condensed juice of Vaccinium oxycoccos fruits and granules “Cranberry” in a model of acute bacterial cystitis in rats.

Materials and methods. The anti-inflammatory properties of condensed juice from Vaccinium oxycoccos fruits and granules “Cranberry” were studied in a model of acute bacterial cystitis in rats, which was caused by three daily transurethral injection into the bladder of 0.3 ml of E. coli strain at a concentration of 106 CFU/ml. “Canefron® H” was used as a reference drug. Tissues were studied histologically by assessing the structure of the bladder wall and the condition of blood vessels.

Results. Infection of animals with E. coli resulted in a significant increase in the desquamation of the transitional epithelium, edematous changes and narrowing of blood vessels in the tissues of the bladder wall. During treatment with the drug “Canefron® N” there was a decrease in cell infiltration and desquamation of cells, dilation of blood vessels. When animals used condensed juice from Vaccinium oxycoccos fruits and granules “Cranberry” in the histological picture of the walls of the bladder there was a decrease in desquamation, edema and cellular infiltration, the lumen of blood vessels was approaching normal.

Conclusions. The use of condensed juice from Vaccinium oxycoccos fruits and granules “Cranberry” was accompanied by a positive effect on the tissues of the walls and blood vessels of the bladder of rats (there was a decrease in desquamation of the superficial layers of the transitional epithelium and normalization of the histological picture of vascular entanglement, that was not inferior to the comparison drug “Canefron® N”.
