Abstract
Potassium cyanide was hypodermically injected in the dose of 2.5 mgrms. per kilo of body weight into rabbits, normal, doubly suprarenalectomized and doubly splanchnicotomized as well.
A hyperglycaemia of a moderate strength occurred in normal rabbits constantly, whereas some experimentalists using a similar dosage have failed to elicit such a constant outcome.
Double suprarenalectomy did not largely interfere with the magnitude of hyperglycaemia due to cyanide, while double splanchnicotomy was capable of very conspicuously abolishing the effect of cyanide upon the blood sugar concentration.
It is thus elucidated that the hyperglycaemia in the cyanide intoxication is to a very large extent of the central origin, but existence of the suprarenal glands has only a small share in eliciting this hyperglycaemia.
