Abstract:
1. The enzyme present in the pneumonic lung exudate still remains active after preservation for 18 months. 2. The enzyme is active at incubator temperature before and after heating to 65 degrees C. for 1 hour. It is slightly active at room temperature and inactive after heating at 75 degrees C. for 1 hour. 3. Dialysis of the enzyme is not demonstrable. 4. Activity persists when the enzyme is mixed with concentrations of sodium chloride varying from normal to thirty-two times normal.

01:25Pleural Effusion I: Introduction
Pleural effusion is an abnormal fluid accumulation in the pleural cavity, a narrow space between the lungs and the chest wall. It is not a disease per se but rather a symptom or indication of an underlying disease. In normal circumstances, this space contains a small amount of fluid (5 to 15 mL), a lubricant facilitating the non-frictional movement of the pleural surfaces.
There are two main types of pleural effusion: transudative and exudative. They are differentiated using Light's criteria,...

01:15Dialysis
Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...
