we suggest that the increase in erythrocytic ph was caused by the action of elevated adrenaline and noradrenaline levels in the blood acting on beta-adrenergic receptors on the trout red blood cell , causing the cell to swell and raising intracellular ph , offsetting any effect of a reduction of plasma ph on erythrocyte ph and haemoglobin-oxygen binding .
