Abstract

Scavenging abilities of animal sera against six reactive species (OH[rad], O2 −[rad], RO[rad], t-BuOO[rad], H3C[rad], and 1O2) were determined with the use of multiple free-radical scavenging (MULTIS) method. Commercially available sera from pig, horse, rabbit, Guinea pig, hamster and chicken were subjected to MULTIS analysis and the results were compared with human specimen. In general, animal sera showed lower scavenging ability against OH[rad] and RO[rad] radicals than human serum. However, it is noteworthy that rabbit and chicken sera have higher scavenging ability against O2 −[rad] than others. This is consistent with the known data that superoxide dismutase levels in these sera are high. In addition, we determined the uric acid level in animal sera using the uricase-TOOS method. In chicken serum, uric acid was found to be the major effective component in RO[rad] scavenging. This paper is first to quantitatively evaluate antioxidant capacities in animal sera.
