Evaluation of Citrate-Phosphate- Dextrose-Adenine as a Storage Medium for Packed Canine Erythrocytes

The storage of hard-packed red blood cells in citrate-phosphate-dextrose (CPD) and CPD-adenine (CPDA-1).

The preservation of red cells "hard packed" to a hematocrit of over 80% from blood collected in citrate-phosphate-dextrose (CPD) or CPD-adenine (CPDA-1) has been investigated. After 21 days of storage, cells that had been collected in CPD solution had consumed most or all of the available glucose and manifested markedly impaired viability after reinfusion into the normal donor. In contrast, red...

Fast hemoglobins and red blood cell metabolites in citrate phosphate dextrose adenine stored blood.

Blood was drawn from 10 fasted, healthy volunteers and stored under standard blood bank conditions in citrate-phosphate-dextrose-adenine (CPDA-1). Blood was sampled before storage (Day 0) and on Days 5, 12, 19, 26, and 35. Laboratory testing for glucose, HbAla + b, HbAlc, pyruvic acid, lactic acid, adenosine triphosphate (ATP), 2, 3-diphosphoglycerate (2,3DPG), plasma free hemoglobin (Hb) and p...

Phosphate compounds of the rabbit red blood cell during storage in acid citrate dextrose (ACD) and ACD-inosine.

Red blood cells of the rabbit appear to react about the same as those of the human to storage in acid citrate dextrose (ACD) preservative in the cold; the cells of both species show a posttransfusion survival of approximately 70 per cent at three weeks and less than 50 per cent at six weeks. The fall in survival is accompanied by a reduction in the glycolytic rate and in the organic phosphate c...

Erythrocyte preservation. VII. Acid-citrate-dextrose-inosine (ACDI) as a preservative for blood during storage at 4 degree C.

Behavior of Packed Bed Thermal Storage

A packed bed thermal storage has several desirable characteristics to be used for energy storage. The behavior of packed bed is predicted by set of differential equations. A numerical solution is developed for packed bed storage tank accounting to the secondary phenomena of thermal losses and conduction effect. The effect of heat loss to surrounding (K1), conduction effect (K2) and air capacita...
