Effect of some autonomic drugs on heat defence in the pigeon.

As compared to the time of median control death (i.e. the time inducing 50% death in untreated birds at 50 degrees C), exogenous noradrenaline afforded 100% survival in the blue rock pigeon, Columba livia. The survival percentages with the other autonomic drugs were: chlorpromazine 70%; reserpine 60%; adrenaline 60%; pentolinium 50% and dihydroergotamine 30%. The time of median control death at 50 degrees C was found to be 3.5 hours in the pigeon. During 10-day exposure at 45 degrees C all the birds pre-treated with noradrenaline survived, and 47% of those treated with adrenaline and 42% of the untreated birds survived the stress. It is concluded that noradrenaline acts definitely as a "heat protective" hormone in the pigeon.
