Shock induces a long-lasting elevation of blood glucose inAplysia

Abstract
Glucose, and not trehalose, was found to be the main blood sugar inAplysia californica. Changes in blood glucose in response to stress produced by electric shock were measured in blood obtained both from animals dissected within ten minutes of shocking and from catheterized animals at various intervals, up to two and a half hours after the shock. Electric shock increased blood glucose levels. The rise in blood sugar continued as long as two and a half hours after shock.
