    Abstract:
    The efficacy of a novel Prunus domestica bark extract (Sitoprin, CR002) was investigated on testosterone propionate (TP)-induced benign prostatic hyperplasia (BPH) in male Wistar rats. BPH was induced by daily subcutaneous administration of TP (3.0 mg/kg) over a period of 15 days (interim sacrifice group) and for an additional 21 days (terminal sacrifice group). We evaluated the dose-dependent efficacy (0, 50, 100 and 200 mg/kg body weight/day) of CR002 and a control group against BPH, and compared with a reference standard Prunus africana extract (CR001). Extensive clinical examinations were carried out on days 1, 7, 14, 21, 28 and 35 of treatment period to determine the onset, duration and severity of clinical signs. Clinical pathology, hematology, biochemistry and histopathology were performed on days 15 and 35, prior to necropsy. Animals were fasted overnight prior to blood collection. Prostate glands and tissues were examined. On day 36, histopathology of ventral prostrate of control rats demonstrates single layer of columnar mucin secreting epithelial cells along with a lumen occupied with eosinophilic secretion. In contrast, CR002 and CR001 groups (100 and 200 mg/kg/day) exhibited no hyperplasia and proliferation of epithelial cells. Prostate histopathology of these treated groups was comparable with control rats. The hyperplasia and hypertrophy of prostrate was reduced to single-layered cell indicating the efficacy of CR002 and CR001. Overall, results demonstrate that CR002 exhibits therapeutic efficacy/activity in TP-induced BPH in rats, which is comparable to CR001.
