Arthritis means joint inflammation.. It causes pain and swelling in the body's joints, such as the knees or hips. There are many types of arthritis, but osteoarthritis is the most common. Also known as degenerative joint disease or age-related arthritis, osteoarthritis is more likely to develop as people get older.
Hydrogen cyanide (HCN), sometimes called prussic acid, is a chemical compound with the chemical formula HCN. It is a colorless, extremely poisonous and inflammable liquid that boils slightly above room temperature, at 25.6 Â°C (78.1 Â°F).
On the other hand, the concentration of hydrogen cyanide may rapidly reach lethal levels if it is released in confined spaces. The most important toxic effect of hydrogen cyanide is by inhibiting the metal-containing enzymes. One such enzyme is cytochromoxidase, containing iron. This enzyme system is responsible for the energy-providing processes in the cell where oxygen is utilized, i.e., cell respiration. When cell respiration ceases, it is no longer possible to maintain normal cell functions, which may lead to cell mortality. Symptoms of cyanide poisoning vary and depend on, for example, route of poisoning, total dose and the exposure time. If hydrogen cyanide has been inhaled, the initial symptoms are restlessness and increased respiratory rate. Other early symptoms are giddiness, headache, palpitations and respiratory difficulty.
