Objective To investigate the expression of plasminogen activator inhibitor 1(PAI 1) in renal cortex of streptozotocin induced diabetic rats and its modulation by taurine Methods After taurine was given to streptozotocin diabetic rats for 14 weeks, angiotensin converting enzyme (ACE) activity, angiotensin Ⅱ(AngⅡ) content, tissue type plasminogen activator (t PA) and PAI 1 bioactivity in renal cortex were determined PAI 1 mRNA expression in renal cortex was measured by Northern blot hybridization...
