Time-related shape control modifications during erythrocyte storage with additive solutions.

To obtain more detailed information on the reversibility of shape alterations in blood bank stored erythrocytes, we have studied shape recovery after chemical crenation and rheological properties in 8 PAGGS-sorbitol preserved erythrocyte concentrates during a five week storage period under blood bank conditions. Our results show that red cell capability to regain a normal discoid shape after chemical crenation decreases during storage but is not lost over a five week period. Moreover there is a significant but weak correlation between red cell ATP content and both shape recovery capability and viscosity. Our results confirm suspicious that red cell shape perturbations following blood bank storage are widely reversible. Two different mechanisms may be involved in reducing shape recovery capability during storage, namely an ATP-dependent mechanism and an energy-independent one. The energy dependent mechanism may be preserved by the previous addition of solutions which maintain higher energy levels during storage.

Fibronectin decrease in liver cirrhosis is related to spleen size.

We found a significantly lower plasma fibronectin concentration in cirrhotic patients than in controls, a significant inverse relationship between fibronectin and spleen size, but no correlation between fibronectin and hepatic blood flow, prothrombin time, or serum albumin. We suggest that the increased degradation in the enlarged spleen is more relevant than the decreased synthesis in reducing plasma fibronectin levels during liver cirrhosis with portal hypertension.
