A Trial Examining the Treatment of Common Warts With Combination Liquid Nitrogen (LN2) and Cantharidin
Summary
The purpose of the study was to see if liquid nitrogen, a commonly used treatment for warts, is more effective if it is used alone, or if it is more effective if combined with cantharidin, a topical treatment also commonly used for warts (verruca vulgaris).

Medical and Biotech [MESH] Definitions
Nitrogen Isotopes
Stable nitrogen atoms that have the same atomic number as the element nitrogen, but differ in atomic weight. N-15 is a stable nitrogen isotope.
Nitrogen Fixation
The process in certain BACTERIA; FUNGI; and CYANOBACTERIA converting free atmospheric NITROGEN to biologically usable forms of nitrogen, such as AMMONIA; NITRATES; and amino compounds.
Countercurrent Distribution
A method of separation of two or more substances by repeated distribution between two immiscible liquid phases that move past each other in opposite directions. It is a form of liquid-liquid chromatography. (Stedman, 25th ed)
Nitrogen Radioisotopes
Unstable isotopes of nitrogen that decay or disintegrate emitting radiation. N atoms with atomic weights 12, 13, 16, 17, and 18 are radioactive nitrogen isotopes.
Blood Urea Nitrogen
The urea concentration of the blood stated in terms of nitrogen content. Serum (plasma) urea nitrogen is approximately 12% higher than blood urea nitrogen concentration because of the greater protein content of red blood cells. Increases in blood or serum urea nitrogen are referred to as azotemia and may have prerenal, renal, or postrenal causes. (From Saunders Dictionary & Encyclopedia of Laboratory Medicine and Technology, 1984)
