Hypochlorite-induced alterations to canine serum complement

Changes in the concentration of the components of complement produced by NaOC1 both in vitro and in vivo are recorded. C1, C4 and C7 are particularly sensitive to this oxidizing agent, although all components decrease at high concentrations of NaOC1. Following oxidation, complement componenets return rapidly to normal. Data are presented to indicate that part of this repair mechanism is due to the action of reducing agents such as ascorbic acid and part is due to the synthesis of the individual components. The unique sensitivity of complement components to oxidation make this treatment of potential value in suppressing the inflammatory response.
