Specific direct radioimmunoassay of angiotensin II (AT II) in human plasma and the effect of angiotensin converting enzyme (ACE) inhibitor.

Specific direct radioimmunoassay of angiotensin II (AT II) in human plasma was developed to evaluate the dynamics of endogenous AT II in various types of hypertension. Detection limit of this method was less than 2.3 pg/ml, and normal value is less than 25 pg/ml.

[Prognostic factors for muscle-invasive bladder cancer treated with a combination of intra-arterial chemotherapy and low-dose radiotherapy].

Clinical and pathological factors that affect short-term responses and long-term prognosis of muscle-invasive bladder cancer were studied in 73 patients who underwent a combination of intra-arterial chemotherapy and low-dose radiotherapy. Complete Response (CR) was observed in 41 (56%) of the 73 patients. The frequency of CR was significantly different according to the sex (males 64%, females 29%; p = 0.
