补阳还五汤及其四类有效部位对脊髓损伤大鼠大脑运动皮质的神经保护作用
The Neuroprotective Effect of Buyang Huanwu Decoction and its Four Kinds of Active Fractions on Cerebral Motor Cortex in Spinal Cord Injury Rats
摘要
Abstract
〔Abstract〕 Objective To observe the effect of Buyang Huanwu decoction (BYHWD) and its four kinds of active fractions (alkaloid, glycoside, polysaccharide and aglycone) on cerebral motor cortex in spinal cord injury (SCI) rats, and then explore the proper mechanism of the neuroprotection. Methods A total of 48 adult Sprague-Dawley rats were randomly divided into eight groups: control group, sham-operation group, SCI group, BYHWD group, alkaloid group, glycoside group, polysaccharide group and aglycone group (n=6). SCI model was performed by cutting the right half spinal cord at the level of T3-T4. Motor function of lower limb was assessed with Basso-Beattie-Bresnahan (BBB) scale at the following moments respectively: 1 d before operation, and 1 d, 1 w, 4 w and 8 w after operation. Ratio of cell apoptosis in cerebral motor cortex was detected by TUNEL staining after 8w treatment. Results Compared with the control group and sham-operation group, the BBB scores in SCI and all medicine intervention groups decreased significantly (P<0.01). After four weeks of operation, the BBB scores in BYHWD and alkaloid groups were significantly higher than the SCI group (P<0.05). After eight weeks of operation, the BBB scores in BYHWD, alkaloids and glycoside groups were higher than that in SCI group (P<0.05). After eight weeks of operation, the ratio of cell apoptosis in SCI and all medicine intervention groups was significantly higher than the normal and sham-operation groups (P<0.01). The ratio of cell apoptosis in BYHWD, alkaloid and glycoside groups was lower than that in SCI group (P<0.01 or P<0.05); while ratio of cell apoptosis in alkaloid, glycoside, polysaccharide andaglycone groups were significantly higher than that in BYHWD group (P<0.01 or <0.05). Conclusion BYHWD can promote the recovery of the motor function in SCI rats. The alkaloids and glycoside may be the most important important material base of BYHWD. Its mechanism may be associated with inhibiting neuronic apoptosis of SCI rats.关键词
