Silicosis is a long-term lung disease caused by inhaling large amounts of crystalline silica dust, usually over many years.Silica is a substance naturally found in certain types of stone, rock, sand and clay.Working with these materials can create a very fine dust that can be easily inhaled.ilicosis is a long-term lung disease caused by inhaling large amounts of crystalline silica dust, usually over many years.
Creatine Phosphokinase (CPK). Creatine phosphokinase (a.k.a., creatine kinase, CPK, or CK) is an enzyme (a protein that helps to elicit chemical changes in your body) found in your heart, brain, and skeletal muscles. When muscle tissue is damaged, CPK leaks into your blood.reatine Phosphokinase (CPK).

Creatine Kinase. Creatine kinase formerly known as creatine phosphokinase is primarily found in muscle cells including the heart, striated muscles and the brain. The normal range of creatine kinase for men is 38 - 174 units/L and for women 96 - 140 units/L. Men typically have more muscle mass than women which accounts for the higher range values. African Americans have been found to have higher normal range for creatine kinase as well.
