DescriptionNitrogen is a chemical element with symbol N and atomic number 7. At room temperature, it is a transparent, odorless diatomic gas. Liquid nitrogen is used principally in cryotherapy for removal of diseased skin. Liquid nitrogen helps in removal of skin lesions through necrosis, which results from the freezing and thawing of cells. Cryotherapy usually done in doctors' office. Also, nitrogen is very famous component in fertilizers and energy-stores.

Affected OrganismHumans and other mammals
IndicationLiquid nitrogen is used mainly as a cryogenic agent for the treatment of various benign and malignant skin lesions.
Mechanism of actionIn cryotherapy, mechanism of action could be classified into three stages: 1. heat transfer, 2. cell injury and 3. inflammation. Boiling point of liquid nitrogen is -196°C, which is the responsible for creating the initial stage which is heat transfer. The second stage is cell injury which is induced during thawing conditions of the cells. The last step in the cryotherapy is the inflammation stage which is characterized by edema and erythema. Inflammation occurs as a result of cellular death and it helps in local cell destruction.
