1.4 Chemical Determination. Proteins are complex, organic compounds composed of many amino acids linked together through peptide bonds and cross-linked between chains by sulfhydryl bonds, hydrogen bonds and van der Waals forces.
Common causes of pleurisy include trauma, postcardiac injury, infection (i.e., viral, bacterial, or parasitic), respiratory illness, caustic exposure (i.e., drug-induced), autoimmune disease, and malignancy (TABLE 1).
A variety of underlying conditions can cause pleurisy. Treatment of pleurisy involves pain control and treating the underlying condition. Pleurisy occurs when the pleura â a membrane consisting of a layer of tissue that lines the chest cavity and a layer of tissue that surrounds the lungs â becomes inflamed.
