The body has a remarkable defence system. Part of its immunity is the production of specialized molecules called immunoglobulins that attach to invading or foreign matter within the bloodstream to form a larger molecule that is removed from the system by entrapment in lymph glands or envelopment by white blood cells specialized in recognizing immunoglobulin-antigen complexes. Immunoglobulins are often referred to as antibodies.
Science has been able to replicate very few immunoglobulins, which can be injected into an individual and generally offer protection against specific diseases such as hepatitis A for up to six months. Some complementary AIDS protocols include the use of immunoglobulins such as gamma globulin which can also be used in other immunosuppressive conditions.
Immunoglobulins have their place in modern medicine. If the body is failing to defend itself then these compounds can be life-saving. There is some anecdotal evidence that immunoglobulins, being foreign proteins themselves, may stimulate an immune response from the body and problems may be associated with the other compounds that are injected during the manufacturing process. I feel that if an individual is liable to be in a situation where the disease is present, from which the immunoglobulin is due to protect them, there are grounds to use these short-lived treatments.
