Research Abstract

Abnormal sensory perception in diabetes mellitus is very severe complications, which make patent life very inconvenient. The curative regimen for this complication does not established so far. The present study was investigate the novel mechanisms underlying in the diabetic sensory abnormal perception in the experimentally (streptozotocin-treated) induced diabetic mouse model. Intra-thalamic treatment with glutamate NMDA and AMPA receptor antagonist reduced the thermal and mechanical hypersensitivity in diabetic mice. This treatment did not affect the thermal and mechanical threshold in non-diabetic mice. Intra-thalamic treatment with glutamate, NMDA receptor agnonist and AMPA receptor agonist produced mechanical and thermal hypersensitivity in mice. Moreover, the expression of microglial marker Iba1 immunoreactivity was increased in diabetic mouse thalamus. These results suggested that abnormal sensory perception in diabetes mellitus may be due, in part, to the sensitization of pain pathway in the supraspianal site.
