Abstract
In this study, we investigated the inhibition of spontaneous canine benign prostatic hyperplasia by a crude polysaccharide fraction extracted from Urtica fissa roots and stems. After oral administration of U. fissa polysaccharide fraction for 3 months, the dog prostatic volume reduced significantly when compared to that before treatment using CT examination. The high-dosage U. fissa polysaccharide fraction (120 mg/kg body weight/day) and finasteride (0.5 mg/kg body weight/day) treatments showed both almost 30 % reduction of the initial prostatic volume. At the end of the administration of U. fissa polysaccharide fraction, the prostates were excised, and the volumes were measured by water displacement. The prostatic volume showed significant decrease by 11 %, 15 %, and 21 % for the 30, 60, and 120 mg/kg/day U. fissa polysaccharide fraction treatment groups, respectively, compared to the control group. Histological observation found that U. fissa polysaccharide fraction inhibited the dog prostatic epithelial cells proliferation and enlarged glandular lumen diameter. The crude polysaccharide fraction of U. fissa is a possible new candidate for the treatment of benign prostatic hyperplasia.
