Species differences in insulin secretory responses during hemorrhagic shock.
Insulin secretory rates (ISR) during intravenous glucose tolerance tests (IVGTT's) were measured in six dogs subjected to hemorrhagic shock and were compared to ISR's from five monkeys subjected to shock of comparable severity. ISR's also were measured in normotensive control dogs and monkeys subjected to the same blood sampling protocol. A sixfold increase in ISR occurred in shocked dogs after glucose loading; however, no ISR response occurred in monkeys subjected to hemorrhage. It is concluded that marked species differences exist in the insulin-glucose metabolic responses to shock. In addition, the dog would appear to be an inappropriate experimental animal as applied to trauma-insulin metabolism in man.
