| Popis: | SummarySerial determinations of the hematocrit and the whole blood, plasma and red cell amino nitrogen concentrations were carried out during prolonged hemorrhage and shock in rats. It was shown that, due to the high concentration of amino nitrogen in the red cell, as compared to the plasma, the whole blood amino nitrogen fluctuates with the hematocrit, while the plasma amino nitrogen more closely reflects the degree of shock. In a large series of rats a rise in plasma amino nitrogen of 1 mg % or more after a 2.5 to 2.7 % hemorrhage was invariably associated with a fatal outcome. |
