Scientists have found that blacks harder than whites to suffer infections of the lower parts of the urinary system and often suffer from prostatic hypertrophy.

Dr. Sarma, who examined 182 African-American for 4 years came to the conclusion that most of them have this pathology are more prone to progression than white Americans. This fact can not fully brand name levitra explain the difference in quality of life of these ethnic groups. According to the first National Health and Nutrition Examination Survey Epidemiologic Follow-up Study (U.S.) in studies in humans and animal experiments revealed that deficiency of retinoids play a role in the development of prostate cancer.

It was recently revealed that the levels of endogenous retinoic acid in tissues of prostate cancer is lower than in normal organs (J Clin Endocrinol Metab., 1996). In addition, its effects on the prostate gland as well as on the line of its cells indicate the involvement of retinoids in the regulation of its growth.

A way to restore an injured or lost urethra invented specialists of the department of urology endoscopic Moscow Academy of Postgraduate Education at the hospital Administration of the President and the CCB ICS. More recently, patients here have started to form from the urethra tissue cheek.As reported by the newspaper Moskovsky Komsomolets, the department of urology endoscope, to such an unusual surgical techniques have come by experience. The fact that the urethra forms a very delicate fabric and its vosstavleniya requires the same. Patients with severely damaged or completely lost the urethra tried to make it out of the mucous membranes of various organs, including the mucosa of the bladder. But the results left much to be desired: a large percentage of complications, and the new urethra is poorly performed their duties.The flap is very thin layer of the epithelium was removed from the inside of the cheeks and formed from his urethra, transplant patient. Urethra is virtually indistinguishable from the present and externally, and on physiological indicators. Doctors can see the reason for this is that the epithelium of the cheek most similar in structure to the urethral mucosa. In addition, the inner part of the cheek is best adapted to different influences (eg, temperature) than any other mucous membranes.
