	Inflammation and immune suppression by Dr. Howard F. Loomis (Site not responding. Last check: 2007-11-05)
		Contrary to television commercials and prevailing medical practices, inflammation should not be suppressed or treated as a disease condition.
		Yet, suppressing the symptoms of fever, redness, swelling, or pain through pharmaceutical means has become usual and customary.
		Leukine is presently used to increase the size and function of white blood cells in patients whose immune function is being depleted by chemotherapy used for the treatment of cancer.

	Welcome to Immune Recovery Clinic - International Cancer Treatment Centers
		In the case of cancer, IRC hopes to induce an immune rejection attack on the tumor similar to the reaction that rejects organ and tissue transplants; part of this is induction of natural killer cells.
		However, the immune suppression seen is in large part due to other pre cancer conditions and it is this immune suppression which has allowed the cancer to arise and survive.
		The IRC immune restoration approach is basic to treating all forms of cancer, it is with the additional therapy directed to the specific tumor types that certain cancers require a specific approach, dependent on cancer cell type, stage of the cancer and the patients physical status.

	Immune system - Wikipedia, the free encyclopedia
		The immune system also performs surveillance of tumor cells, and immune suppression has been reported to increase the risk of certain types of cancer.
		The adaptive immune system is based on dedicated immune cells termed leukocytes (white blood cells) that are produced by stem cells in the bone marrow, and mature in the thymus and/or lymph nodes.
		Suppression of the immune system is often used to control autoimmune disorders or inflammation when this causes excessive tissue damage, and to prevent transplant rejection after an organ transplant.

	Immunodeficiency - Wikipedia, the free encyclopedia
		In medicine, immunodeficiency (or immune deficiency) is a state in which the immune system's ability to fight infectious disease is compromised or entirely absent.
		Immune suppression is a common side-effect of many drugs, most importantly chemotherapy.
		However, Disease-modifying antirheumatic drugs (DMARDs) are used to suppress immune activity in autoimmune disorders to slow progression of this type of disease.

		Alternatively, subtle changes in certain immune functions could conceivably increase the likelihood of adverse immune-related health effects only during the brief period when these effects are present, or these changes may result in minor health changes unlikely to be disclosed in an epidemiology study.
		Variability among the population with respect to immune status, the inability to objectively measure the immune function, and the confounding factors involved in interpretation of these measures decrease the probability of using broad-based epidemiologic studies to identify xenobiotics that are responsible for causing immunologic injury.

	Environmental Chemical Exposures and Risk of Herpes Zoster (Site not responding. Last check: 2007-11-05)
		Because the immune system is crucial for the protection of the host against infectious agents and developing neoplasms, enhancement or diminution of any essential immune function could offset the balance necessary for immunoregulation and produce a cascade of secondary effects, including compromised host resistance.
		In phase 1, the indicator of immune suppression is self-reported episodes of herpes zoster and recent occurrence of other common infectious diseases such as colds and flu.
		In phase 2, immune suppression is assessed on a subset of participants from phase 1 with a battery of laboratory measures of immune competence such as numbers and types of white blood cells as well as frequency of lymphocyte micronuclei, an indicator of chromosome damage.

		Model systems established to study the link between immune suppression and tumor development showed that cutaneous exposure to moderate doses of UVB (280-320 nm)t radiation induce systemic suppression of T-cell-mediated contact hypersensitivity to haptens and delayed-type hypersensitivity (DTH) responses to protein antigens such as herpes simplex virus, leishmania, Candida albicans and mycobacteria (2-5).
		Furthermore, studies by Streilein's laboratory suggest that susceptibility to UV-induced immune suppression of T-cellmediated contact hypersensitivity responses may be a risk factor for the development of skin cancer in humans (6).
		Poly/oligosaccharides from A. barbadensis were previously shown to influence the regulation of murine immune responses to UV radiation and to prevent the release of the immunosuppressive cytokine IL- 10, in vitro and in vivo (I1).

		Research was conducted to determine whether the immune suppression observed in periparturient cows could be ameliorated by 'force feeding' cows through a rumen cannula in the immediate periparturient period.

		We demonstrated that the presence of the mammary gland affects the degree of immune suppression experienced by the cow during the periparturient period.

		Because the immune suppression induced by UV exposure is a major risk factor for skin cancer induction, the primary focus of my research effort is to determine the mechanism(s) involved.
		Therefore, it is critical to understand the mechanism involved in jet fuel-induced immune suppression in order to design therapies to reverse its immune suppressive effects.
		Because we see identical dose-response curves regardless of whether we use JP-8 or Jet-A, and since identical mechanism are involved (PAF and PGE2 induction) in immune suppression we conclude that the immune suppressive properties of jet fuel are inherent in the base kerosene fuel.

		According to the current paradigm, the role of the immune system is restricted to eliminating foreign ‘’non-self" structures, and it does not concern itself with the body’s own "self-structures".
		In our opinion, we must enlarge the immune system’s role to include the disposal of a constant stream of "altered self-structures." The disposal of exogenous "non-self" structures is to be regarded as a secondary function, called upon only when the need arises.
		The immune system’s main function is the constant elimination of endogenous cell debris, and when necessary, the disposal of foreign structures.
