Trientine and renin-angiotensin system blockade ameliorate progression of glomerular morphology in hypertensive experimental diabetic nephropathy.

A comparison of the efficacy of the copper chelator, trientine, with combined renin angiotensin system (RAS) blockade on the progression of glomerular pathology in the diabetic (mREN-2)27 rat is reported. Animals were treated for 2 months with trientine, combined RAS blockers, combined trientine plus RAS blockers or none. Treatments began after inducing diabetes with streptozotocin.
