In 2001 , African-Americans were three times more believably to yield from asthma than were Whites (American Lung connexion 2007The Agent of Disease Asthma is a chronic inflammatory dis of the skyways in which many cells and cellular elements childs play a role , in particular , mast cells eosinophils , T-lymphocytes , macrophages , neutrophils , and epithelial cells (Admas , 1998 ,. 45 . Asthma may cause permanent lung defame in the form of fibrosis (scarring . The main characteristics of this disease are : tinder , airway obstruction , bronchial hyperresponsiveness , fibrosis .

There are two classes of helper T-cells , TH1 and TH2 .TH1 cells are instrumental in our confession against what are known as intracellular infections , whic h are produced by microorganisms such as the tuberculosis bacterium that invade and tucker out it on within our cells . TH2 cells are normally employed in the defence against other organisms , specifically parasites more commonly associated with equatorial infections . These cells produce cytokines , chemicals that have a profound effect on the body s immune response (Bromberg , Ph . et al 2006 Admas , 1998Factors think to the PopulationAccording to statistical results , this racial group is affected more than other nationalities (American Lung Association , 2007 . Researchers have not identified specific factors which cause asthma within African-American population but consult destitution , lack of education inadequate healthcare function and hearty measures as the main risk factors . Thus , Adams admits patrimonial prevalence of African-Americans to respiratory disease including asthma (Adams 1998 .
