Conivaptan and an initial study shows that it has some promise. Conivaptan is most commonly used in the hospital in cases of euvolemic and hypervolemic hyponatremia, conditions where the sodium level in the blood falls significantly below normal. In the United States hyponatremia affects about four percent of hospitalized patients. Although many patients do not show symptoms, extreme cases may result in brain swelling, respiratory arrest and even death. Hypervolemic hyponatremia specifically is when the body’s serum sodium levels fall below the total body water increase, which results in edema. This is associated with congestive heart failure, liver disease and kidney
Serum protein electrophoresis blood serum (the fluid portion of the blood after the blood has clotted) is applied to an acetate membrane soaked in a liquid buffer., to a buffered agarose gel matrix, or into liquid in a capillary tube, and exposed to an electric current to separate the serum protein components into five major fractions by size and electrical charge: serum albumin, alpha-1 globulins, alpha-2 globulins, beta 1 and 2 globulins, and gamma globulins. Proteins are separated by both electrical forces and electroendoosmostic forces. The net charge on a protein is based on the sum charge of its amino acids, and the
