The first reaction produced by taking nitrate of silver internally is a
combination of this salt with the proteinaceous tissues with which it
comes in contact, as also a precipitation of chloride of silver.
According to Mitscherlich, the combination with the proteine or
albuminous substance is not a permanent one, but suffers a decomposition
by various acids, as dilute acetic and lactic acid.
The absorption of the silver into the system is slow, as the albuminoid
and chlorine combinations formed in the intestinal canal cannot be
immediately dissolved again.
In the tissues the absorbed silver salt is decomposed by the tissues,
and the oxide and metallic silver separate.
Partly for this reason and partly on account of the formation of the
solid albuminates, etc., the elimination of the silver from the body
takes place very slowly. Some of the silver, however, passed out in the
faeces, and, according to Lauderer, Orfila, and Panizza, some can be
detected in the urine.
Bogolowsky[1] has also shown that in rabbits poisoned with preparations
of silver, the (often albuminous) urine and the contents of the (very
full) gall bladder contained silver.
