??the Breakdown of Immune System

The sectionalization of Immune System Andy 1131400011 English? Liver Pool 2012. 10. 19 Diseases always suddenly burst into peoples lives and leave long scars for these patients. There are many diseases are so serious that have global warp in human history. As the article The Evolution and Break shine of Immune System wrote, The breakdown of tolerant establishment is one of the most frequent and dangerous diseases all over the world. (Jonsson, Brokstad, Hansen, Davies & Ulevestad, 2002) It not only influences the patients, but impacts their families, and level worse, they may become the burden of the whole society.Every patient really suffers lots of pain when they fight with these mixed bags of diseases. They will simply influence your immune scheme, the guardian of your body, nonetheless destroy it. Patients may get sick and find it hard to recover once there have some disturbance come from the outside environment. aid is one of the most influential diseases of them. Accor ding to the dates from UNAIDS, in2010, there are totally 33. 3 million people who suffer lots of pain for AIDS in the earth (UNAIDS, 2010).People who get AIDS will become unbelievably vulnerable and can only lengthen their life under some medical help. The influence of these kinds of diseases will expand from personal to social. Patients families are the first who will bear the torture of worries and sadness. Immune system is hard to rebuild after break down so the patients families have to pay money for their treatment conclusionlessly. Once they do not have enough money, the patient can only wait for the end of the life, which will bring families huge pain.Only in Africa, 23 million people who died because of AIDS in 2010 (UNAIDS, 2010). And there are millions of families suffer the hurt caused by AIDS. non only the patients families will suffer a lot when they try to save the patients, the society also weighs down by the expenditure to treat patients. In 2009, US$ 15. 9 billion was used to get all kinds of available sources for human immunodeficiency virus, but in 2010 there will have $ 26. 8 billion needed for HIV services, and the scholars said there will have a long period ncrease because of the growth of patients who is infected by AIDS (UNAIDS, 2010). Since extensive impacts caused by immune system breakdown, if we can find some causes of it, there may have some favorable change in our future. Based on its different causes, it is usually dual-lane into three main parts immunodeficiency, autoimmunity and hypersensitivity. Immunodeficiency is first type, which refers to diseases that can make the ability of immune system to fight infectious disease is compromised or entirely absent.Most cases of this kind of diseases are acquired but some people are born with defects in their immune system, or primary immunodeficiency. One example provided by Dr. Greenberg is the mix-use of things which can run across our body, such as syringe needles and to a faultt hbrush (Greenberg, 2009). So we should be careful to our actions in our daily lives. The second is autoimmunity, which contains diseases are caused by the failure of an organism in recognizing its own constituent parts as self, which allows an immune response against its own cells and tissues.It is often caused by a lack of germ development of a get body. The immune system may fight with each other regardless of the corporations. Some scientists regard overstress and overwork as two main reasons of these kinds of diseases (Clare, 2003). It gist the irregular living style may lead to the breakdown of the immune system. Lastly is hypersensitivity. It refers to undesirable reactions produced by the normal immune system, including allergies. Many of them are caused by unhealthy living habits in our daily lives (Allen, 1999).Maybe some people always eat a lot once they find something is delicious, maybe they spend too much time in a certain environment, all these may cause the breakdow n of our immune system. After we are aware of the bad influences of immune system breakdown on patients, families and society after we research and trace its causes and divide them into three main types, immunodeficiency, autoimmunity and hypersensitivity, we really hope that the breakdown of the immune system will leave less pain on peoples lives.But unfortunately, immune system breakdown is still one of the most destructive diseases in the world.
