NF-kB expression in midbrain periaqueductal gray induced by electrical stimulation of dura near superior sagittal sinus in rats / 中华神经科杂志

Objective To investigate the role of nuclear factor-kappa B(NF-?B)protein in the nociceptive transmission of migraine attacks and NF-KB expression in the periaqueductal gray(PAG) induced by electrical stimulation of dura mater near the superior sagittal sinus(SSS)of the rats. Methods The rats were prepared by exposure of the superior sagittal sinus.The dura mater near the SSS was stimulated and NF-?B protein was detected in coronal brain sections using standard avidinbiotin immunohistochemistry.Results The number of NF-KB positive neurons in PAG expression increased to 111.7?15.7 in stimulation group,compared with 112.9?10.7 and 508.7?30.8 in blank group and sham-operated group respectively(t=-41.52 and t=-36.21,P
