Washington ( reuters ) - people with migraines also may be suffering from some brain damage as brain cells swell and become starved of oxygen - - a finding that may help explain why migraine sufferers have a higher risk of stroke , researchers reported on sunday 華盛頓(路透社)研究人員于本星期日報道說,偏頭痛患者也有可能遭遇腦細胞膨脹而缺氧引發的腦損傷,這一發現解釋了為什么病人有很高的中風危險
Halocin c8 appeared to have a very wide activity spectrum , including most haloarchaea and even some haloalkaliphilic rods , but it showed no inhibitory activity against bacterial strains tested . when a sensitive strain of halorubrum saccharovorum atcc29252 was exposed to halocin c8 , the treated cells swelled at the initial stage , the cell wall appeared to be nicked and the cytoplasm was extruded out afterwards , and the whole cell was eventually completely lysed 將敏感菌株halorubrumsaccharovorumatcc29252的細胞用嗜鹽菌素c8處理后,采用電鏡觀察,發現處理2小時后細胞開始腫脹、膨大,接著在細胞的兩端出現裂口,細胞內容物開始向外溢出,隨著時間延長,裂口越來越大,發生這種變形的細胞也越來越多,最后,幾乎所有的細胞完全裂解。
