2.Methods Using the WD method of Allen,the L1 of spinal cord in rats was formed the incomplete spinal cord injury. The areas of spinal cord injury were separately treated with millimeter wave in various parameters(wave-length,4.9 mm,7.1 mm,8.9 mm and power density 2 mW/cm2, 7 mW/cm2,20 mW/cm2). The therapeutic method was 30 min/per time,twice a day,for 20 days.
3.Methods:In experimental rats,the lumbar region(L1) of spinal cord was formed the incomplete injury by Allen method. Then,the injured spinal cords were locally irradiated by millimeter wave with different parameters,such as wave-length 4.9mm,7.1mm,8.9mm and power density 2mW/cm 2,7mW/cm 2,20mW/cm 2,separately. The course of treatment was 20 days.
4.1 plan in three sides; front, side and ground, with the specification of its materials and size in mm(millimeter).
5.8 Millimeter wave attenuation characters of expanded graphite worms with different length distribution are tested. The results show that attenuation gets to the maximum 11.61 dB when the sizes of expanded graphite worms are in 2.7～3.9 mm. This expanded graphite is potential screening material to interfere electromagnetic wave at wide wave band.
6.Methods The L1 of spinal cord in 24 Wistar rats was formed the incomplete spinal injury using the WD method of Allen,then these rats were divided into four groups. Among them,two groups as treatment group were separately treated with 7.1 mm-7 mW/cm 2 and 7.1 mm-20 mW/cm 2 of millimeter wave 30 min/per time,twice a day,for 20 days.
