SUMMARY AND CONCillSION
Blood is a biological fluid. consisting of formed
elements. the red blood cells. the white blood cells and •
the platelets. all suspended in a fluid media. the plasma.
These formed elements require a source of energy in order
to maintain its function and to survive in the blood for
its normal life span. The main source of energy is glucose.
Preserved blood is expected to vary considerably from
that circulating inside the vessels.
The aim of the present work is to determine the possible
effects of blood storage in CPDA-l on the plasma proteins
( total and differential ) and on some immunoglobulins.
During donation of blood for storage. certain precautions
are taken to avoid harmful effects for the blood donated.
Blood was received in plastic bags containing CPDA-l anticoagulant.
It was then thoroughly mixed and divided into
4 aliquots through the connecting tube and kept Ln the blood
bank refrigerator at 4°C. These bags were examined in the
first day of storage, after one week. three weeks and five
weeks of storage. They were examined for I
_ Plasma proteins ( total and differential ).
IgG, IgM. and 19A.
In our work, we found no significant difference in the
64
plasma proteins (total and differential ) between the
levels of the first day and the levels after five weeks
of storage.
Also there was no significant change in the concent-
.rations of IgG, IgM and 19A after five weeks of storage.
from this, we conclude that many useful fractions can
be ..obtained from the plasma of the stored CPDA-l blood.
One of these fractions is the albumin which is the major
budgetary item for many hospital blood banks. It is used
mainly for hypovolemia in surgery or trauma and for chronic
hypoalbuminemia in nephrosis, cirrhosis and the malabsorption
syndrome and may be used to maintain the obligatory
extracellular space, as in severe burns.
Immunoglobulins are also useful preparations and can
be used effectivly in the treatment of hypogammaglobulinemia.
