用定量图象分析方法,对5例严重的肺脂肪栓塞尸解病例进行测定。每例均从经福尔马林固定的肺脏切取5个组织标本。全部组织浸入0.5％锇酸液中过夜,然后用冰冻切片机切至8μm厚,用装有连接装置的快速图象感受器系统进行图象分析。这个系统能从周围组织中区别脂肪栓塞。因为高密度的栓塞在锇酸中染黑,它的大小通过连接的计算机能计算出来。在每 Quantitative image analysis was used to determine the incidence of severe pulmonary embolism in 5 cases. In each case, five tissue specimens were obtained from formalin-fixed lungs. The whole tissue was immersed in 0.5% osmium tetroxide overnight and then cut to a thickness of 8 μm using a cryostat. Image analysis was performed using a rapid image sensor system equipped with a connecting device. This system distinguishes fat embolism from the surrounding tissue. Because the high density of the plug is black in osmium tetroxide, its size can be calculated by the connected computer. In every
