Abstract

In the experiment performed on 96 rabbits, by means of silver nitrate impregnation and Gerota mass injection methods, changes in the epicardial lymphatic bed have been investigated after 5-minutes' clinical death caused by hemorrhage. During first hours after resuscitation certain signs of the lymphatic drenage activation are revealed. In most of the animals the specific density of the lymphatic bed increases, capillaries and postcapillaries dilate, hyperargirophilia of cytoplasm and nuclei of endotheliocytes appears. In the animals sacrificed against the background of a severe state (with certain, signs of a pronounced hypoxia), there are dystrophically and degeneratively altered endotheliocytes. This is accompanied with hyper- hypoargyrophilia of endothelium, fragmentation of its cell borders, with deterioration of injection ability of the lymph outflow pathways. In the rabbits survived, by the 7th-14th days a gradual normalization of the parameters studied takes place.

摘要

在对96只兔子进行的实验中,通过硝酸银浸渍法和热罗塔团块注射法,研究了出血导致5分钟临床死亡后心外膜淋巴床的变化。复苏后的最初几个小时内,可发现淋巴引流激活的某些迹象。在大多数动物中,淋巴床的比密度增加,毛细血管和后微静脉扩张,内皮细胞的细胞质和细胞核出现嗜银性增强。在处于严重状态(有明显缺氧的某些迹象)背景下处死的动物中,内皮细胞出现营养不良性和退行性改变。这伴随着内皮细胞嗜银性的增强和减弱、细胞边界的破碎,以及淋巴流出途径注射能力的下降。在存活的兔子中,到第7 - 14天,所研究的参数逐渐恢复正常。
