Effect of cooling on tissue capacity for catecholamine trapping
1980
The paper deals with capacity of tissues of the bull and rat auricle and of the rat deferent duct for trapping L-[3H] noradrenaline and [3H] adrenaline under different conditions of cooling. It is established that at the preliminary incubation temperature of 20 degrees C the intensity of tissues trapping both the hormone and mediator is essentially decreased and [3H] noradrenaline does not inhibit the adrenaline trapping. When the bull auricle tissue is cooled down to 4 and 0 degrees C its capacity for the [3H]-noradrenaline trapping is restored. The rat deferent duct tissue recover its capacity to the [3H] adrenaline trapping after cooling down to 0 degrees C. Freezing down to -20 and 196 degrees C has a pronounced inhibitory effect on the [3H] adrenaline and [3H] noradrenaline trapping by all the tissues under study. Possible thermodependence mechanisms of the adrenergic mediator-hormones trapping are explained.
