It has been shown that the frequency of ABO blood groups differs between populations [1,3]. Determination of the frequency of blood groups in a particular region facilitates timely provision of blood and blood products. There are many studies on the distribution of blood groups in Turkey [4-10]; however, none have considered Kayseri Province, a densely populated city in central Anatolia. As suc...

Although ABO incompatibility between mother and fetus has long been suspected as cause of spontaneous abortion in man, its precise contribution has not been completely resolved. In spite of reports in which the incompatible mating was recognized to be a cause of habitual abortion, and which eventually results in infertility or a reduction in the number of living children compared with the numbe...

While the technique of cross-circulation has been used extensively in physiology, it has usually been employed with large animals. The present paper describes a method of cross-circulation that has been successfully adapted to the rat. The use of this species offers certain advantages: (a) animals are uniform in structure as a result of continued inbreeding, (b) blood types are similar and cons...

Several instruments are now available for full automation of serologic testing in the transfusion service. Selection of an instrument is based on the facility's needs for testing and its resources. Installation, validation, interfacing, and operations require new skill sets for most transfusion service personnel. The newer instruments are suitable for use in smaller transfusion services, where ...
