[Features of microcirculation in the liver during anaphylactic shock]

Microcirculation in the liver was studied in rats and dogs with anaphylactic shock. Injection of a reacting dose of the horse serum led to elevation of systemic arterial pressure by an average of 20 mm Hg; there also occurred spasm of the sinusoids, hepatic venules and an acceleration of blood flow in them With the following blood pressure reduction to 60-40 mm Hg there was blood congestion in the vessels, retarded circulation, intravascular aggregation of the blood formed elements, hemorrhages and ischemic changes. Restoration of systemic arterial pressure and of microcirculation occurred in parallel; no complete normalization of microcirculation in the liver ensued, yet.
