Abstract
Changes in myeloperoxidase(MPO)and glucosephosphate isomerase(GPI)activities in the neutrophil of the common carp, Cyprinus carpio, inflamed with turpentine were examined in this study.
MPO activity continued to increase up to its maximum value(38.3±16.1×10-8) 12 h after the injection of turpentine at a dose of 1 ml/kg body weight, but soon reverted to the control level. On the other hand, GPI activity decreased 30 min after injection and the lowest activity(6.9±3.4×10-8) was observed after 1-3 h. The activity reverted to the control level after 24 h.
These results, along with similar enzymatic studies on mammalian inflammation suggest that inflammation enhances the digestive ability of neutrophils in carp as well as in mammals.
