Abstract
INTRODUCTION: Plasma sialic acid levels are elevated in Diabetes Mellitus (DM) patients with proteinuria. Renal damage is mainly caused by free radicals that are excessively generated in DM. Thiols play an important role in the cellular antioxidative defence mechanisms mainly through thiol-disulphide exchange reaction. Diallyl disulphide, a garlic oil principle component, is known for its anti-diabetic properties. Its structural analogue, Diaceto-Dipropyl Disulphide (DADPDS), is a less toxic and more palatable disulphide and possesses similar anti-diabetic actions. AIM: This study was undertaken to assess the usefulness of DADPDS in prevention of de-sialation of Glomerular Basement Membrane (GBM) in alloxan diabetic rats and to assess effect of DADPDS on renal tissue thiol levels. MATERIALS AND METHODS: Rats were divided into Normal, Diabetic and DADPDS treated diabetic groups. Diabetes was induced by intraperitoneal injection (IP) of alloxan. DADPDS was fed by gastric intubation. Plasma Sialic acid was determined by Ehrlich's method and renal tissue thiol levels by Nitroprusside reaction method. RESULTS: This study showed a significant decrease (p<0.001) in plasma sialic acid, plasma glucose and renal tissue TBARS levels along with significant increase (p<0.001) in renal tissue thiol levels in DADPDS treated alloxan diabetic rats when compared to diabetic control rats. CONCLUSION: Hence it may be concluded that DADPDS helps in preventing de-sialation of GBM in alloxan diabetic rats and improves renal tissue antioxidant defence mechanisms, may be through thiol-disulphide exchange reaction and thereby exhibits a possible clinical use in prevention of renal complications like diabetic nephropathy.
