title: Fenugreek seed extract treats peripheral neuropathy in pyridoxine induced neuropathic mice.
abstract: Trigonella foenum graecum commonly known as Fenugreek exerts normoglycemic and insulinotropic effects in humans by compounds from its seed and leaf extracts. Some studies reported that treating pregnant mice with fenugreek seed could cause toxic effects on the nervous system of its pubs during developmental growth, while in some other studies neuroprotective properties were considered for it. Safety of anti-diabetic drugs for nervous system is very important because peripheral neuropathy is a common complication of diabetes and hazardous drugs could worsen it. In this study, the effect of treatment with fenugreek seed extract on the function of sciatic nerves of neuropathic mice was evaluated. Neuropathy was induced in male mice by pyridoxine intoxication. After that, animals were treated with 0.2, 2 and 20 mg/kg of hydro-alcoholic extract of fenugreek seeds for 10 days, tail flick, electrophysiological and histological assays were performed to evaluate the effect of fenugreek seed extract on function of the peripheral nerves. Our data showed that fenugreek has anti neuropathic effect and restores the function of nerve fibers. Results of electrophysiological recordings stated that the highest rate of healing was occurred in 20 mg/kg fenugreek extract treated animals. In conclusion, findings of the present study demonstrate that treatment with fenugreek seed extract can potentially facilitate healing from pyridoxine induced peripheral neuropathy in mice.
