Cactus flower extracts may prove beneficial in benign prostatic hyperplasia due to inhibition of 5alpha reductase activity, aromatase activity and lipid peroxidation.

The cactus flower is deemed to be helpful in benign prostatic hyperplasia (BPH) therapy, although there is no published information regarding its clinical effect in patients and on the mechanism of its biological activity. The present study evaluated the ability of cactus flower extracts to exert an effect on BPH through possible inhibition of such processes as lipid peroxidation, androgen aromatization and testosterone reduction. Cactus flower extracts indeed inhibited aromatase and 5alpha reductase activity in cultured foreskin fibroblasts, and also in human placental and prostatic homogenates.

Mixed adenocarcinoma and neuroendocrine carcinoma arising in the urachus. A case report and review of the literature.

Primary urachal carcinomas are very rare urological malignancies. In the present article we report an unusual case of a small cell carcinoma with neurendocrine features and adenocarcinoma arising in the urachus, and review the literature. The results of the immunohistochemical studies are presented.

Environmental and nutritional factors significantly associated with cancer of the urinary tract among different ethnic groups.

A high incidence rate of urinary tract cancer in the Acre District among the Jewish population compared with the non-Jewish population has been studied. The dietary and environmental factors identified and the possible mechanisms of the protective effect that may be conferred by fluid intake, olives and olive oil, cumin, and pepper (chili pepper and pepper) are discussed.
