HENLE'S REACTION OF THE CHROMAFFIN CELLS IN THE ADRENALS, AND THE MICROSCOPIC TEST FOR ADRENALIN

We have established the fact that the chrome reaction as well as the silver and osmium reactions are merely reductions by adrenalin. In our opinion the naming of the cells giving a positive reaction should not be based upon the reaction i.e., chromaffin cells), but on the presence of adrenalin itself. Biedl's terms, adrenal cell, adrenal organ, adrenal body, adrenal system, and also Bonnamour's term, adrenalin-producing cells, are appropriate in this respect. We propose the names adrenalin cell, adrenalin tissue, adrenalin system, thereby indicating the presence of adrenalin.
