膀胱肿瘤是泌尿系的常见肿瘤,近年来,发病率有升高趋势。已知膀胱肿瘤的发病与机体吸收某些外源性芳香胺有关,色氨酸代谢紊乱导致内源性芳香胺的堆积可能也是膀胱肿瘤的原因。同时,实验表明,膀胱肿瘤患者尿β-葡萄糖醛酸甙酶(β-Glucuronidase,简称 GRS)活性明显增高。但是,对尿 GRS Bladder neoplasms are common tumors of the urinary system. In recent years, the incidence has increased. It is known that the onset of bladder cancer is related to the body’s absorption of certain exogenous aromatic amines, and that the accumulation of endogenous aromatic amines may be the cause of bladder cancer. At the same time, experiments have shown that the activity of urinary β-Glucuronidase (abbreviated as GRS) in patients with bladder tumors is significantly higher. However, for urine GRS
