INS and ischemia: The metabolic and hormonal systems are affected in relation to blood glucose, adrenal stress response, level of circulating adrenaline and noradrenaline, release of insulin and peripheral utilization of glucose, serum potassium, release of neurotransmitters in response to ischemia, ability of receptors to bind and take up noradrenaline, complement activation, release of angiotensin, interleukins, cytokines, beta-endorphines, and anti-diuretic hormones.
