High glucose driven reactive oxygen intermediates production and inflammatory damage are recognized contributors of nerve dysfunction and subsequent damage in diabetic neuropathy. Sulforaphane, a known chemotherapeutic agent holds a promise for diabetic neuropathy because of its dual antioxidant and anti-inflammatory activities. The present study investigated the effect of sulforaphane in streptozotocin (STZ) induced diabetic neuropathy in rats. For in vitro experiments neuro2a cells were incubated with sulforaphane in the presence of normal (5.5 mM) and high glucose (30 mM). For in vivo studies, sulforaphane (0.5 and 1 mg/kg) was administered six weeks post diabetes induction for two weeks. Motor nerve conduction velocity (MNCV), nerve blood flow (NBF) and pain behavior were improved and malondialdehyde (MDA) level was reduced by sulforaphane. Antioxidant effect of sulforaphane is derived …
