Abstract

In the present study, we examined electron microscopically and immunohistochemically the effects of perindopril, an angiotensin-converting enzyme inhibitor, on renal microangiopathy in streptozotocin-induced diabetes in rats. To investigate changes in glomerular basement membrane (GBM) and tubular basement membrane components, we immunohistochemically localized type IV collagen and laminin. Animals have been divided into three groups of eight adult male rats each. The first group was the non-diabetic control group. The second group consisted of untreated diabetic rats. The third group consisted of diabetic rats that were treated with perindopril for 6 weeks. Blood glucose levels and body weight were measured. Morphometric analysis of kidney tissue was performed using light and electron microscopy to quantify glomerular size and thickness of the GBM. Blood glucose levels in diabetic rats were significantly increased when compared with non-diabetic controls. Blood glucose levels were not affected by perindopril treatment. Untreated diabetic rats showed increased glomerular size, thickening of the GBM and an increase in mesangial matrix as compared with controls. Treatment with perindopril prevented effectively glomerular hypertro...Continue Reading

Basement Membranes

Basement membranes are thin, specialized extracellular matrices surrounding most tissues in all metazoans. Here is the latest research on basement membranes.
