[Histometric characteristics of capillary-glio-neurocytic relationships of cervicothoracic (stellate) ganglia of cats during experimental isadrine-induced myocardial necrosis].

Focal myocardial necrosis in cats (Felis domestica) was provoked by means of threefold subcutaneous administrtion of isadrin at a rate of 10 mg bw. Cervicothoracic nodes of the boundary sympathetic trunk normally and experimentally were subjected to morphologic and histometric analysis (after 3 hours, 3--7 days and 2 weeks). The presence of foci of myocardial necrosis was supported by electrocardiography data and histologic examination of the myocardium. Histometric analysis of the cervicothoracic nodes revealed shifts in the microcirculatory channel and in the neurocytic-glial complexes. A correlation was revealed between the time course of electrocardiography data on focal myocardial necrosis and consistently developing time-dependent histopathologic changes in the cervicothoracic nodes which are specific for them in acute metabolic myocardial necroses.
