Anthocyanin is a natural plant pigment and potent antioxidant. This study was designed to investigate the effects of anthocyanin extracted from black soybeans on rat model benign prostatic hyperplasia (BPH), disease associated with geriatric population. Thirty male rats were divided into five experimental groups: control group, BPH-induced three groups that received oral doses (40, 80, 160 mg/kg). Prostate induced by administration testosterone propionate for 4 weeks. Following BPH...

Inflammation is a crucial response to harmful stimuli, but its chronic activation contributes various diseases, including inflammatory bowel disease, osteoarthritis, and neurological disorders. While nonsteroidal anti-inflammatory drugs are widely used as anti-inflammation drugs, their extended usage often results in severe side effects, emphasizing the need for safer alternatives. Therefore, it of greatest importance identify discover new agents that exhibit reduced incidence adverse...
