Objective : Benign prostatic hyperplasia(BPH) is one of the most common diseases among elderly men. In BPH, dihydrotestosterone (DHT) acts as a potent cellular androgen and promotes prostate growth. Many reports conclude the component melittin in bee venom has the potential to treat various diseases including prostate cancer. In this study, we investigated the therapeutic effects and action mechanism of Bee venom herbal acupuncture with BPH induced by castration and testosterone treatment. Methods : Sprague-Dawley rats were treated with testosterone after castration for induction of experimental BPH. A total of 24 rats were equally divided into four groups: Group 1 was the model group; Group 2 served as control (sham-operated group); Group 3 animals were treated with Bee venom herbal acupuncture as an experimental specimen; Group 4 served as a positive control group and was treated with finasteride at a dose of 1 mg/kg. The drugs were administered orally. The prostates were evaluated by prostatic weight, volume, histopathological changes and testosterone levels. Results : While prostates of control rats revealed severe acinar gland atrophy and stromal proliferation, the rats treated with Bee venom herbal acupuncture showed a diminished range of tissue damage and showed significant decrease in their prostatic weights, volume and histopathological examination. Conclusions : These results suggest that Bee venom herbal acupuncture may protect the glandular epithelial cells and also inhibit stromal proliferation. From theses results, we suggest that Bee venom herbal acupuncture could be a useful remedy agent for treating the benign prostatic hyperplasia.
