Physical and chemical changes of ACD-preserved blood: a comparison of blood in glass bottles and plastic bags.

ACD blood was preserved in glass bottles with or without aeration and in plastic bags in air or nitrogen gas at 4.5 degrees C. The blood was examined for physical and chemical changes of erythrocyte membrane resistance, hemoglobin in the plasma, the viscosity of the blood, pH of plasma, and ATP and 2,3-DPG content of erythrocytes. The blood preserved in plastic bags showed less changes than blood in glass bottles. The presence of air or nitrogen gas in blood seems to increase the pH perhaps by elimination of carbon dioxide (CO2) which in turn causes the different rates of glycolysis in the erythrocytes.

[Changes in the blood coagulating properties of preserved blood and the native and lyophilized plasma of cattle during storage].

Studied were some of the indices characterizing the blood clotting system (thrombocytes, fibrinogen, recalcified clotting time, CA-thromboplastin time, kephalin-kaolin time, thrombin time. F II, and F V) in preserved glucose-citrate blood kept at 4 degrees C, in untreated bovine plasma kept at 20 degrees C, 4 degrees C, and -20 degrees C, and in freeze-dried bovine plasma. It was concluded that bovine blood preserved with L-12 could be used as a hemostatic agent up to the 10th day after it was obtained; untreated plasma could be used up to one month after it was obtained; and freeze-dried plasma could be used up to two months after it was obtained. Following freeze-drying the coagulation properties of the plasma remained active for more than a year, and it could also be used as a hemostatic agent.
