Destruction of the sympathetic ganglia in mammals by an antiserum to a nerve-growth protein

Abstract
Antiserum against the salivary gland protein not only inactivates the protein, but, if injected alone into a newborn mammal, destroys its sympathetic cells without affecting other tissues or organs Daily injections for a period of 8 days results in the disappearance of up to 99% of the sympathetic nerve cells. The suggestion is made that the salivary glands are not the site of production of the nerve-growth agent but merely store it; the agent may possibly be manufactured in the mesenchyme.
