It was shown that the root elongation was inhibited and the malonaldehyde content in root apices and the antioxidase activities of root apices were increased under Al stress (30 μmol/L), while the effects of Al were significantly alleviated by the addition of Si (1.4 mmol/L). Moreover, both Si added before Al treatment and Si added simultaneously with Al treatment could alleviate these effects. On the other hand, the cultivar of Seca was shown to be more sensitive to Al than other cultivars in the absent of Si, while Al-resistance distinction among the cultivars of stylosanthes turned to be non-significant in the present of Si in the pre-cultured solution or both pre-cultured and Al-treatment solutions.

研究结果表明，在铝(30 μmol/L)胁迫条件下柱花草根伸长受阻、根尖丙二醛含量和抗氧化酶活性显著增加，而硅(1.4 mmol/L)处理增加根中硅的含量而降低了铝对根伸长、MDA含量和抗氧化酶活性的影响，且铝处理前12h供给的硅和前处理溶液及铝溶液中均加硅处理的影响均显著；在不加硅条件下西卡品种的耐铝性显著低于其它品种，而经硅预处理的植株和在预处理及铝处理期间均供应硅的植株的耐铝性不同品种间的差异不显著。

There were no significant differences for the firing rates in the site of contralateral TNC neurons among during pre-CSD,CSD,and post-CSD (P＞0.05).For flunarizine group,the firing rates in the site of ipsilateral TNC neurons during pre-CSD were higher as compared with during CSD(P＜0.05).2.1 There were statistical differences on palasma levels of CGRP and SP among the three groups(P＜0.05).The levels of CGRP and SP in CSD group were higher than control group(P＜0.05).No significant differences on the levels of CGRP and SP in ipsilateral trigeminal ganglia were found among the three groups(P＞0.05).2 The number of neurons with positive CGRP and SP immunoreactivity was statistically different in right-sided trigeminal ganglia among the three groups (P＜0.05).The number in fight-sided trigeminal ganglia in CSD group was higher as compared with control group(P＜0.05).The number in right-sided trigeminal ganglia was statistically higher than that in left-sided trigeminal ganglion in CSD group(P＜0.05).3.1 Altered ReHo in ipsilateral pons and other brain regions response to pain such as basal nuclei,thalamus,cingulated gyms and prefrontal cortex was detected during the acute spontaneous attack as compared with during headache remission(P＜0.05,corrected by Monte Carlo simulation). 2 Positive functional connectivity was detected between ipsilateral pons and other brain regions related to pain within pain state and within non-pain state (P＜0.05,corrected by false discovery rate,FDR).Increased functional correlation between ipsilateral pons and other pain-related brain regions such as ipsilateral prefrontal cortex and contralateral subcallosal gyrus was detected during the acute spontaneous attack as compared with during headache remission(P＜0.05,corrected by Monte Carlo simulation).
