Effect of Excluding the Splanchnic Nerves or the Suprarenal Medulla upon Hyperglycaemia in Dogs Due to Anaphylactic Shock

Abstract

Anaphylaxis was induced in dogs, which were previously either doubly splanchnicotomized or deprived of the medulla of the suprarenal glands.
That the hyperglycaemic period is preceded in some cases by a transitory, small decrease of the blood sugar and that it makes its appearance first when the animal has already become depressant and that the arterial blood pressure tends to recover from the rapid and enormous fall, were also found in these dogs as in normal animals. But the magnitude of the increase of the sugar concentration is usually more or less smaller in these kinds of dogs in comparison with the normal ones, notwithstanding that the clinical symptoms were of similar strength in these three sets of animals and the blood pressure fall was on a rather greater scale in the dogs operated on than in the normal.
