Aim of the studyTo assess the effectiveness of the traditional Chinese herb Phellodendron amurense in treating urological disorders.Materials and methodsProstate smooth muscle relaxant activity of an extract from the bark of Phellodendron amurense was tested on contractions of isolated rat prostate gland induced by electrical nerve stimulation and direct muscle stimulation.ResultsElectrical field stimulation (0.5 ms, 60 V, 1–20 Hz) induced nerve mediated contractions of isolated rat prostate were inhibited by Phellodendron amurense extract dissolved in either dimethylsulfoxide (DMSO), acetic acid or water (P ≤ 0.022, n = 6 for each) but not boiling water (P = 0.619, n = 6). Phellodendron amurense extract also inhibited contractions of isolated rat prostates elicited by exogenous administration of noradrenaline (10 nM to 100 μM), acetylcholine (10 nM to 100 μM) or adenosine 5′-triphosphate (ATP, 100 nM to 100 μM) (P ≤ 0.004, n = 6–8 for each).ConclusionPhellodendron amurense is able to inhibit prostatic contractility suggesting that it may be useful in the treatment of urological disorders caused by prostatic urethral obstruction such as in the case of benign prostatic hyperplasia (BPH).
