BLOOD CALCIUM DISTRIBUTION IN ANAPHYLAXIS IN THE GUINEA PIG.

The results above reported for total calcium and the membrane-diffusible fraction in the serum of the guinea pig, taken at various intervals during anaphylactic shock, confirm the findings of previous workers that the total calcium is essentially unchanged. There is, however, the further finding that the diffusible fraction is considerably increased over that found for the animal similarly treated but not manifesting characteristic symptoms.
