Even though the blood has been subdivided into groups, the Rh factor has been discovered, and we know already that the texture of our blood may be either coarse or fine (similar to the skin with its coarse or fine pores), there are many singularities of the blood that remain unknown. Just think of the mysteries surrounding the content and structure of an individual’s blood. It is left to the scientists to lift the veil as time goes by.

If the blood, this truly mysterious red fluid of life, had already been sufficiently researched, there would hardly be some 20,000 deaths a year due to blood transfusions in the United States alone.
In the future, it is probable that surgeons, having been made aware of the great risks involved in transfusing human blood, will only make use of the much improved and effective non-blood plasma and blood replacements that are now available. Let me also mention that hepatitis, a much feared inflammation of the liver with infectious jaundice, has frequently resulted from blood transfusions. The prevention of serum hepatitis as a consequence of blood transfusions is a problem that has not yet been solved. In more recent times, AIDS too has been passed on through blood transfusions. Considering that even the medical director of an American blood bank has expressed serious concern over the risks involved in transfusions and that many surgeons, as a result of unsatisfactory experiences, prefer to work with substitutes, is there
any wonder that the patient should wish to express his personal preference, talk it over with the surgeon and then make his own decision?
