After the use niter benzene even treatment and the treatment all around, separately makes the electroencephalogram inspection to two groups of case of illness.results: after the use niter benzene even treatment all around, the treatment group electroencephalogram restores quickly to the comparison group, exceptionally leads obviously to be lower than the comparison group.conclusions: the niter benzene is even is treats the recovery period fluorine acetamide to be poisoned patient's effective method, may enable his/her the brain harm to obtain the as soon as possible repair, improves the brain function, makes the unusual electroencephalogram to restore normal or the change for the better as soon as possible.

在使用硝苯地平治疗前和治疗4周后，分别对两组病例均作脑电图检查。结果：使用硝苯地平治疗4周后，治疗组脑电图恢复快于对照组，异常率明显低于对照组。结论：硝苯地平是治疗恢复期氟乙酰胺中毒患者的有效手段，可使其脑损害得到尽快修复，改善脑功能，使异常的脑电图尽早恢复正常或好转。

Cytotoxic effect was demonstrated with nitrogen mustard, nitromin, sarcolysin, thio-TEPA and myleran at concentrations of 7, 10, 25, 35, 100, and 100μg/ml respectively.
