Much of the killing effect results from several powerful oxidizing agents formed by enzymes in the membrane of the phagosome or by a special organelle called the peroxisome. These oxidizing agents include large quantities of superoxide (O2−), hydrogen peroxide (H2O2), and hydroxyl ions (OH−), which are lethal to most bacteria, even in small quantities. Also, one of the lysosomal enzymes, myeloperoxidase, catalyzes the reaction between H2O2 and chloride ions (Cl-) to form hypochlorite, which is exceedingly bactericidal.

Effect of Circulatory Arrest on the Brain
For many years, it was thought that this detrimental effect on the brain was caused by the acute cerebral hypoxia that occurs during circulatory arrest. However, experiments have shown that if blood clots are prevented from occurring in the blood vessels of the brain, this will also prevent much of the early deterioration of the brain during circulatory arrest. For example, in animal experiments, all the blood was removed from the animal’s blood vessels at the beginning of circulatory arrest and then replaced at the end of circulatory arrest so that no intravascular blood clotting could occur. In this experiment, the brain was usually able to withstand up to 30 minutes of circulatory arrest without permanent brain damage.
