Intrauterine asphyxia has been induced in immature and mature newborn rabbits by means of experimental shock of the pregnant doe. Typical changes of clotting parameters and morphological alterations in different organs specific for shock were used as criteria of the maternal shock. For the detection of asphyxia conditioned neonatal organ lesions, liver, lung, kidney and heart muscle were studied light microscopically. Special attention was devoted to liver alterations, i.e. changes of hepatocyte structure, glycogen content and microcirculation disturbances as well as to alterations of the hematopoietic system. The asphyxia related effects were vacuolic degeneration of hepatocytes, centroacinar hyperemia and persistence of hematopoietic cells in the neonatal liver. The alterations of the hepatocytes as well as of the hematopoietic system were more conspicuous in mature then in immature asphyxiated rabbits. On the contrary, the microcirculatory changes are similar in both animal groups.
通过对孕兔进行实验性休克,在未成熟和成熟新生兔中诱发宫内窒息。典型的凝血参数变化以及不同器官中休克特有的形态学改变被用作母体休克的标准。为了检测窒息导致的新生儿器官损伤,对肝脏、肺、肾脏和心肌进行了光学显微镜研究。特别关注肝脏的改变,即肝细胞结构的变化、糖原含量和微循环障碍,以及造血系统的改变。与窒息相关的影响包括肝细胞的空泡变性、肝小叶中心充血以及新生儿肝脏中造血细胞的持续存在。在成熟的窒息兔中,肝细胞和造血系统的改变比未成熟的更为明显。相反,两个动物组的微循环变化相似。
