Objective To observe and analyse the therapeutic effect of pentoxifylline in treating traumatic cerebral infarction.Methods Besides routine treatment received in control group,PTX 0.2～0.6 injection plus 500ml normal saline was intravenously dripped once a day,in the treatment group.Duration ten days as a treatment course in both groups and three courses were carried out.N-acetylaspartate(NAA),choline(Cho),Creatine(Cr) and lactate(Lac) in infarct part of brain were measured with proton magnetic resonance spectroscopy(1HMRS).Results Compared with control group,ability of daily life were better,N-acetyl aspartate(NAA) and creatine(Cr) were obvious higher.Lactate(Lac) were obvious lower,in the treatment group.Conclusion PTX has a better therapeutic effect in traumatic cerebral infarction.
