We investigated the effects of castration and androgen administration on angiotensin II receptor mRNA expression and apoptosis related proteins in the rat bladders. Sprague-Dawley rats were divided into three groups: the control group (sham operation; n = 8), the castration group (castrated, 8 weeks old, n = 8) and the castration plus testosterone group (1% testosterone gel administrated percutaneously into the dorsum daily for 8 weeks starting at 4 weeks after castration, n = 8). Bladder total RNA was extracted, and real-time PCR was performed to quantitatively measure the mRNA expression of angiotensin converting enzyme (ACE), angiotensin II (A II) receptor type 1 (AT1 receptor) and A II receptor type II (AT2 receptor). Western blotting was performed to determine the expression of apoptosis-related proteins. Expression of AT2 receptor mRNA and caspase-3 protein significantly increased in the rat bladder after castration, and these increases were reduced to control levels by testosterone administration. These results suggest that expression of AT2 receptor and caspase-3 in the bladder is androgen-dependent. Expression of Bcl-2 and Bax protein in the rat bladder was not altered by castration. Expression of mitogen-activated protein (MAP) kinase phosphatase-1 protein in the rat urinary bladder was significantly increased by castration, but this increase was smaller with testosterone administration. These results suggest that expression of AT2 receptor mRNA and apoptosis-related proteins in the rat urinary bladder are affected by the change of androgen environment. The present study was the first to clarify the relationship between AT2 receptor and androgen in the urinary bladder.

Pneumonia and urinary tract infections develop in roughly 1/3 of the survivors of cerebral stroke. Post-stroke pneumonia results from aspiration and uroinfection from neurogenic disturbances of urination and bladder catheterization. Post-stroke immune deficiency increases the risk of infectious and inflammatory complications. These conditions are treated in accordance with the general principles of management of these diseases. Prophylaxis of pneumonia is reduced to the principle of "nothing orally" before the swallowing capacity is tested, early mobilization, and oral cavity hygiene. Studies on the role of prophylactic antibiotic therapy and ACE inhibitors in the prevention of post-stroke pneumonia are currently underway. Bladder catheterization under strict indications and the use ofcatheters coated with antibacterial agents or condom urine bags in men are likely to reduce the risk of uroinfection. Infectious and inflammatory complications impair the outcome of stroke. Their prophylaxis and adequate treatment are prerequisites of successful recovery after stroke.
