The nature, extent and duration of changes of the contents of histamine in bovine blood in different phases of postnatal to adrenalin load

The reaction of histaminergic system on the adrenal load of the cows is revealed. Than proves the correlation functional activity of histaminergic and adrenergic systems. The adrenergic systems activation is accompanied by the functional activity in crease histaminergic system.
