Influences of stellate ganglion block and near-infrared irradiation around stellate ganglion on the activity of brain cell

本研究观察了星状神经节阻滞(SGB)和星状神经节周围不同剂量的线性近红外辐射(SGR)对治疗30 mm后额叶皮质脑细胞活动的影响。在SGB中，SGB非阻断侧的相对快活动功率、SEF90值和SMF值在阻断侧增加，阻断侧在20~30 mm之间逐渐增加。在90J/cm2~180J/cm2的SGR组中，双侧快活动的相对功率、SEF90值和SMF值都有所增加。因此，SGB和这些剂量的SGR都激活了脑细胞。尤其是，在90J/cm2和180J/cm2之间的SGR组中，SGB和这些剂量的SGR都激活了脑细胞。尤其是，在90J/cm2和180J/cm2之间的SGR组中，SGB和这些剂量的SGR都激活了脑细胞。90~180J/cm2SGR剂量组与SGB组相比，β波相对功率增加更明显。而360J/cm2SGR组相对快速活动功率、SEF90值和SMF值降低。提示360J/cm2SGR与90~180J/cm2SGR相比对脑细胞活动有镇静作用。结论：90~180J/cm2SGR具有与SGB相同的刺激作用。该SGR治疗对患者无创，90~180J/cm2SGR可用于近期脑激活的治疗。360J/cm~2的SGR有可能抑制脑细胞的过度兴奋性，使其恢复正常。

In this study, it was investigated whether stellate ganglion block(SGB)or several doses of linearly near-infrared irradiation around stellate ganglion(SGR)had some influences on brain cell activity in frontal cortex 30 mm after treatment.Brain waves were measured and performed Fourier transform. Then, we tried to examine changes of 90% spectral edge frequency(SEF90), spectral median frequency(SMF)and relative power of brain waves following treatment.In the SGB, relative power of fast activity, SEF90 values and SMF values were increased 15 min after SGB on the unblocked side and increased between 20 mm and 30 mm by degrees on the blocked side.In the SGR groups between 90 J/cm^2 and 180 J/cm^2, relative power of fast activity, SEF90 values and SMF values increased on bilateral sides.Therefore, it was suggested that both SGB and these doses of SGR activated brain cells.Especially, relative power of theta-wave increased in the dose of 90 J/cm^2 SGR group more than in SGB group.On the other hand, in 360 J/cm^2 SGR group relative power of fast activity, SEF90 values and SMF values were decreased.It was suggested that 360 J/cm^2 SGR had sedative action on brain cell activity as compared with 90-180 J/cm^2 SGR.It was concluded that 90-180 J/cm^2 SGR had the same stimulatory action as SGB.This SGR treatment is non-invasive for patients and 90-180 J/cm^2 SGR will be applied for the treatment of brain activation in the near friture.In addition, there is a possibility that 360 J/cm^2 SGR will suppress hyperexcitability of brain cells and then normalize them.
