Abstract

The present study was designed to check the effect of daidzein in the management of diabetic retinopathy. Streptozotocin at dose 55 mg/kg was used for inducing diabetes in rats. After 28 days of diabetic induction, animals were treated with daidzein at dose 25, 50, and 100 mg/kg for the next 28 days. Electroretinography, estimation of plasma glucose, lactate dehydrogenase, aldose reductase, sorbitol dehydrogenase and oxidative stress parameters were performed at the end of the study. Histopathology of retina was carried out at the end of the study. Diabetic control animals showed a significant increase in levels of plasma glucose and plasma lactate dehydrogenase (p < 0.001). Treatment with daidzein at a dose of 50 and 100 mg/kg significantly reduced the elevated level of blood glucose (p < 0.01 and p < 0.01). Whereas, treatment with daidzein at a dose 100 mg/kg significantly reduced the elevated level of lactate dehydrogenase in plasma after 28 days of treatment (p < 0.01). Treatment with daidzein at a dose of 100 mg/kg significantly reduced the level of aldose reductase and sorbitol dehydrogenase (p < 0.01 and p < 0.001 respectively). Electroretinography revealed that daidzein treatment at a dose of 100 mg/kg significantly pre...Continue Reading
