RESUMO
Diabetic kidney disease is one of the most common microvascular complications of diabetes mellitus with consequences of diabetic nephropathy. Here we amined to evaluate the nephroprotective potential of methanolic Mentha longifolia (MML) against serotonin-induced hypoglycemia allied toxicity in the rat model of diabetes. Diabetes was induced in rats via alloxan administration and validated by blood glucose level measurement. After that, the animals were treated with serotonin and methanolic extract of Mentha longifolia. Surprisingly, serotonin treatment significantly reduced the glucose levels to hypoglycemic conditions, accompanied by impaired redox defense system, abnormal kidney histopathology, dyslipidemia, and altered level of liver toxicity markers. Interestingly these changes were rescued by the methanolic extract of M. longifolia. The present study suggests that impaired serotonin levels during diabetic conditions may accelerate hypoglycemic allied free radical-dependent abnormalities; however, medicinal plants like M. longifolia can reduce these deleterious effects by scavenging free radicals and their associated toxicity.
