Scleral icterus is not a disease in itself but a symptom of an underlying medical condition. When the underlying condition is treated‚ then the scleral icterus is also resolved. Causes: Bilirubin is a pigment that is excreted in bile and urine‚ and is processed by the liver. What occurs in

Hepatitis C 12/02009 By: Shuntrice Hannah Abstract Hepatitis C is an infection of the liver caused by the hepatitis C virus (HCV). It is difficult for the human immune system to eliminate the virus from the body‚ and infection with HCV usually becomes chronic. Over decades‚ chronic infection with HCV damages the liver and can cause liver failure in some people. The hepatitis C virus is transmitted mainly by contact with blood or blood products.

Hypothesis If liver is placed in different temperatures of 0˚C‚ 7˚C‚ 21˚C‚ 37˚C‚ and 90˚C and hydrogen peroxide is added to each piece of liver‚ then the liver placed in 37˚C will have the largest reaction height. The liver in 90˚C will have the smallest reaction height‚ followed by the liver in 0˚C‚ then 7˚C‚ and then 21˚C. Background Information Pearson Baccalaureate:
