A web service differs from a web site in that a web service provides information consumable by software rather than humans. As a result, we are usually talking about exposed JSON, XML, or SOAP services. Web services are a key component in mashups.
Leukopenia is a shortage of white blood cells in the system, which can be caused by anemia, menorrhagia, etc. A low white blood cell count, or leukopenia will have a direct effect on your body's immune system. White blood cells are used to fight off infections within the blood stream. Without an adequate number of white blood cells your body will have trouble ridding itself of bacteria or viral matter which can cause disease.
White blood cells (WBC) are the soldiers of your kitty's immune system, so a low count means the army is low on manpower. These squiggly leukocytes fight infections head-on and sometimes there are casualties. The reason for a low WBC count can be revealed by a blood screening. General Infection While white blood cell count is often discussed in the context of serious illnesses like cancer or immune-deficiency disorders, a low count doesn't always indicate a fatal disease. In fact, pretty much any infection or inflammation causes a drop in WBC count. The cells are attracted to damaged tissue and pathogens.
