Abstract
In normal rabbits compression on the eye for one minute induced a slight degree of hyperglycaemia, the maximum of which was noted in 15 cases being 0.15%. The maximum was reached, on an average, half an hour after compression and the hyperglycaemic period covered on an average about one hour.
The same manipulation was capable of producing only an insig-nificant degree of hyperglycaemia when applied to rabbits, either doubly splanchnicotomized or doubly suprarenalectomized.
In the highest hyperglycaemic period the heart beat was defini-tely accelerated in the majority of cases of normal rabbits, but this acceleration was missed in the cases of doubly splanchnicotomized rabbits. In the doubly suprarenalectomized rabbits the acceleration was noted in half of the cases.
It maybe added by way of precaution that the animals were never-fastened and no anaesthesia was resorted to.
