马兜铃酸对大鼠肾功能和组织病理学影响及川芎嗪与苯那普利的干预作用

目的:通过动物实验,观察大鼠灌胃马兜铃酸(AA)后,肾功能及肾脏组织病理学改变,及川芎嗪、苯那普利对肾损害的干预作用.方法:雄性Wistar大鼠98只,SPF级,随机分为4组:正常对照组20只,实验组分为模型组、川芎嗪组、苯那普利组,每组26只;各实验组按AA 20 mg·kg-1·d-1关木通浸膏灌胃,2 h后按分组灌胃给药.川芎嗪50 mg·kg-1·d-1,苯那普利1.8 mg·kg-1·d-1;正常对照组、模型组灌胃饮用水.各组每周测量体重,分别于第4、8、12周处死动物;腹主动脉采血分离血清,检测肾功能;取肾组织进行病理形态学检查.结果:AA灌胃4周后各组血肌酐/体重水平明显增加,与正常对照组比较有统计学差异;与模型组比较,川芎嗪、苯那普利组血肌酐/体重水平显著降低,提示有改善肾功能作用.肾脏组织病理学可见模型组早期有明显的肾小管坏死,部分小管结构紊乱较严重,空泡变性明显;后期出现间质灶性纤维化,纤维化面积＞30%.川芎嗪、苯那普利治疗组的肾功能和组织学损害程度较轻微,纤维化程度约15%～20%.结论:马兜铃酸对大鼠肾脏具有肾毒性,可导致小管间质损害和肾纤维化.川芎嗪、苯那普利对马兜铃酸肾损害有保护作用,能减轻马兜铃酸造成的肾组织病理损害,减少肾纤维化程度.     

谷氨酰胺在危重病患者中的应用

目的探讨危重病患者中早期经静脉应用谷氨酰胺（glutamine，Gl）的临床价值。方法42例患者随机分成两组（对照组和Gln组），Gln组进行Gln治疗（100mL／d，共7d）。治疗前后检测患者体质量、白蛋白、谷胱甘肽（GSH）、握力的变化和肠功能不全的发生率。结果体质量两组治疗前后比较差异无显著性（P〉0．05）。白蛋白、握力和GSH Gl治疗后非常显著高于治疗前（P〈0．01）；白蛋白对照组治疗后较治疗前显著增高（P〈0．05），但握力和GSH治疗前后均无显著变化（P〉0.05）；肠功能不全的发生率Gln组为4．8％，显著低于对照组（28．6％，P〈0．05）。结论在危重病患者疾病早期通过静脉途径外源性地补充Gln，有效改善了患者的营养状况；使患者血浆中的GSH水平增高，加强了机体的抗氧化能力；减少了患者肠功能不全的发生率。     

Pick’s disease with Pick bodies combined with progressive supranuclear palsy without tuft‐shaped astrocytes: A clinical,neuroradiologic and pathological study of an autopsied case

We report clinical, neuroradiologic features, and neuropathologic findings of a 76‐year‐old man with coexistent Pick’s disease and progressive supranuclear palsy. The patient presented with loss of recent memory, abnormal behavior and change in personality at the age of 60. The symptoms were progressive. Three years later, repetitive or compulsive behavior became prominent. About 9 years after onset, he had difficulty moving and became bed‐ridden because of a fracture of his left leg. His condition gradually deteriorated and he developed mutism and became vegetative. The patient died from pneumonia 16 years after the onset of symptoms. Serial MRI scans showed progressive cortex atrophy, especially in the bilateral frontal and temporal lobes. Macroscopic inspection showed severe atrophy of the whole brain, including cerebrum, brainstem and cerebellum. Microscopic observations showed extensive superficial spongiosis and severe neuronal loss with gliosis in the second and third cortical layers in the frontal, temporal and parietal cortex. There were Pick cells and argyrophilic Pick bodies, which were tau‐ and ubiquitin‐positive in neurons of layers II–III of the above‐mentioned cortex. Numerous argyrophilic Pick bodies were observed in the hippocampus, especially in the dentate fascia. In addition, moderate to severe loss of neurons was found with gliosis and a lot of Gallyas/tau‐positive globus neurofibrillary tangles in the caudate nucleus, globus pallidus, thalamus, substantia nigra, locus coeruleus and dentate nucleus. Numerous thorned‐astrocytes and coiled bodies but no‐tuft shaped astrocytes were noted in the basal ganglion, brainstem and cerebellar white matter. In conclusion, these histopathological features were compatible with classical Pick’s disease and coexistence with progressive supranuclear palsy without tuft‐shaped astrocytes.
