摘要:
We examined the effects of surgical trauma on polymorphonuclear leukocyte (PMN) chemotaxis, production of phagocytosis-dependent intracellular chemiluminescence (CL) and production of phagocytosis-independent total CL in two groups: group A with esophageal cancer, and group B with gastric cancer. The scale of surgical trauma was quantified by measuring interleukin-6 in plasma and exudate from drainage tubes. We found a significant augmentation of chemotaxis, total CL and intracellular CL in both groups during the postoperative week. In group A, the increments in both chemotaxis and total CL of circulating cells were smaller than those in group B, but there was no significant difference in intracellular CL between the two groups. Exudate PMNs were more chemotactic, but produced smaller amounts of total CL than circulating cells. No significant difference in intracellular CL between exudate and circulating PMNs was detected, indicating that phagocytic activity was not affected. We conclude that severe surgical trauma causes ciruclating PMNs with high chemotactic activity to migrate to sites of injury, but that preactivated PMNs in exudate examined in vitro produce lower amounts of reactive oxygen metabolites in response to soluble chemoattractants in vitro than cells circulating in plasma.
