为了研究室周静脉胶原性疾病与及脑白质稀疏之间的关系,作者对22个大脑标本进行子MR成像和神经病理学研究。男11例,女11例,年龄25～95岁,其中20例均为死于医院的60岁以上的老年病人。为了确保标本具有组织学研究价值,均于死亡后2～8小时内取出完整的人脑,置于冰箱冷冻4小时以达到适合切割的硬度。行冠状倾斜1cm切片和自额、顶和枕区取经胼胝体的两半球结合部切层。将1cm厚的大脑切片浸于温度为4℃、含0.4％甲醛、90mmol/L氯化钙、24mmol/L巴比妥钠的水溶液中固定24小
In order to study the relationship between ventricular plexus collagen disease and white matter sparseness, the authors performed sub MR imaging and neuropathological studies on 22 brain specimens. 11 males and 11 females, aged 25 to 95 years old, 20 of whom were elderly patients over the age of 60 who died of the hospital. In order to ensure that the specimens have histological value, all intact human brains were removed within 2-8 hours after death and placed in the freezer for 4 hours to achieve the appropriate hardness for cutting. Coronal oblique 1cm section and from the volume, top and occipital area taken by the corpus callosum hemisphere junction cut. The 1-cm-thick brain slices were immersed in a solution of 0.4% formaldehyde, 90 mmol / L calcium chloride and 24 mmol / L sodium pentobarbital at a temperature of 4 ° C for 24 hours
