Acne occurs when the pores on your skin become blocked with oil, dead skin, or bacteria. Each pore on your skin is the opening to a follicle. The follicle is made up of a hair and a sebaceous (oil) gland. The oil gland releases sebum (oil), which travels up the hair, out of the pore, and onto your skin. The sebum keeps your skin lubricated and soft. Acne can be caused by one or more problems in this lubrication process.

Although the increase in total serum LDH activity is rather nonspecific, it is pro-. posed that measurement of LDH activity levels and its isoenzyme pattern in pleur-. al effusion and, more recently, in bronchoalveolar lavage fluid may provide additional. information about lung and pulmonary endothelial cell injury.
