In order to learn the local changes, especially the degree of the wound which cannot be seen from outside, I gave various experimental conditions by applying electricity of alternating and direct current between both thighs and on one lower limb of rabbits. The following results were obtained by pursuing changes of chemical components in the blood, especially, serum inorganic phosphorus and calcium due to the application of electricity.
1) Inorganic phosphorus in the serum increases while calcium decreases in electric injury.
2) The increase of serum inorganic phosphorus as the result of stimulation by means of the application of more than certain amount of electricity is a phenomenon of inevitable occurrence. It is not a phenomenon which appears only after the occurrence of the electric shock. The increase of serum inorganic phosphorus is already observed by one tenth of the amount of electricity needed for the occurrence of shock. Namely, it is the mark of the application of electricity, which is not enough to produce shock.
3) The increase of serum inorganic phosphorus, when there is no occurrence of shock, is consequent upon the release of phosphorus from the damaged local tissues into the blood stream due to the passage of electricity. It increases or decreases in good proportion to the degree of tissue damage, until the local circulatory disturbances by severe injury appear.
Accordingly, in electric injury the increase of serum inorganic phosphorus becomes a mark of hidden tissue damage. When a shock appears, there is an added portion of increase due to the shock itself, and the increase of serum inorganic phosphorus becomes more marked.
