31. Catecholamines have a half-life of a few minutes when circulating in the blood.32. Ventricular arrhythmias are usually exercise-related, suggesting that they are sensitive to catecholamines . 33. Phosphorylation at Ser40 relieves feedback inhibition by the catecholamines dopamine, epinephrine, and norepinephrine. 34. Deiodination is controlled by numerous hormones and nerval signals including TSH, vasopressin and catecholamines . 35. Type B and Type C necrotizing agent and it induces hypertension by release of catecholamine . 36. The role played by these processes differed between the various catecholamines and the various tissues. 37. Catecholamines are water-soluble and are 50 %-bound to plasma proteins in circulation.38. Included among catecholamines are epinephrine ( adrenaline ), norepinephrine ( noradrenaline ), and dopamine. 39. In emergency medicine, this occurrence is widely known as " catecholamine dump ". 40. It was further found that catecholamines do not markedly alter the fluoride-induced histamine release.
