摘要

Peripheral neuropathic condition is amongst the classical symptoms of progressed diabetes. An intensive glycemic control with insulin injections has been shown to delay the onset and the progression of this condition in diabetes. In this study, we investigated the effect of pectin-insulin patch application on peripheral neuropathic symptoms in streptozotocin-induced diabetic rats. Pectin-insulin patches (20.0, 40.8, and 82.9 mu g/kg) were daily applied thrice in streptozotocin-induced diabetic rats for 45 days. The diabetic animals sham treated with insulin-free patch served as negative control, while diabetic animals receiving subcutaneous insulin served as positive controls. The locomotor activity, gripping strength, and thermal perception were assessed at day 36, day 40, and day 44, respectively. On the 45th day, the animals were sacrificed, after which the plasma insulin, nitric oxide, C-reactive protein, tumor necrosis factor alpha, and malondialdehyde were measured. The patch application attenuated hyperglycemia with an improvement in the locomotor activity, thermal perception, and gripping strength in diabetic animals. Furthermore, the application of the patch augmented plasma nitric oxide while attenuating plasma malondialdehyde and tumor necrosis factor alpha. The application of pectin-insulin patch delays the onset of peripheral neuropathiclike symptoms in diabetic animals.
