There are many causes of<unk> , and as such treatment is based upon how the<unk>  came about. Treatment of<unk>  typically involves two distinct processes: Usually, the underlying cause of the<unk>  must be treated before the dead tissue itself can be dealt with. * Debridement, referring to the removal of dead tissue by surgical or non-surgical means, is the standard therapy for<unk> . Depending on the severity of the<unk> , this may range from removal of small patches of skin to complete amputation of affected limbs or organs. Chemical removal of<unk> otic tissue is another option in which enzymatic debriding agents, categorised as proteolytic, fibrinolytic or collagenases, are used to target the various components of dead tissue. In select cases, special maggot therapy using Lucilia sericata larvae has been employed to remove<unk> otic tissue and infection. * In the case of ischemia, which includes myocardial infarction, the restriction of blood supply to tissues causes hypoxia and the creation of reactive oxygen species (ROS) that react with, and damage proteins and membranes. Antioxidant treatments can be applied to scavenge the ROS. * Wounds caused by physical agents, including physical trauma and chemical burns, can be treated with antibiotics and anti-inflammatory drugs to prevent bacterial infection and inflammation. Keeping the wound clean from infection also prevents<unk> . * Chemical and toxic agents (e.g. pharmaceutical drugs, acids, bases) react with the skin leading to skin loss and eventually<unk> . Treatment involves identification and discontinuation of the harmful agent, followed by treatment of the wound, including prevention of infection and possibly the use of immunosuppressive therapies such as anti-inflammatory drugs or immunosuppressants. In the example of a snake bite, the use of anti-venom halts the spread of toxins whilst receiving antibiotics to impede infection. Even after the initial cause of the<unk>  has been halted, the<unk> otic tissue will remain in the body. The body's immune response to apoptosis, which involves the automatic breaking down and recycling of cellular material, is not triggered by<unk> otic cell death due to the apoptotic pathway being disabled.
