Use of 2 deoxy-D-glucose to test for the completeness of surgical vagotomy

An assessment of the reproducibility and safety of 2-deoxy-D-glucose as a gastric acid stimulant in duodenal ulcer patients

In studying the effects of 2-deoxy-D-glucose (2-DG) on the vagus nerve in preoperative patients with duodenal ulcer we have concluded that (1) in initiating gastric acid secretion 2-DG produces a response that is reproducible after 30 days; (2) 2-DG when given in a dose of 40 mg/kg intravenously produces a glucopenic state that appears safe in an otherwise healthy patient. We consider that 2-DG is a worthwhile agent in the investigation of the duodenal ulcer patient.

Factors which determine the gastric secretory response to 2-deoxy-D-glucose

The physiological factors which determine the penetration of the brain by 2-deoxy-D-glucose have been studied and the practical importance of the blood-brain barrier has been demonstrated. The evaluation of the gastric secretory response to 2-deoxy-D-glucose has been shown to depend upon the plasma glucose concentration. It is concluded that because of the hazards and uncertainties in the use of 2-deoxy-D-glucose in man its use is to be deprecated.

Factors affecting maximal acid secretion

The mechanisms by which different factors affect the maximal acid secretion of the stomach are discussed with particular reference to nationality, sex, age, body weight or lean body mass, procedural details, mode of calculation, the nature, dose and route of administration of a stimulus, the synergistic action of another stimulus, drugs, hormones, electrolyte levels, anaemia or deficiency of the iron-dependent enzyme system, vagal continuity and parietal cell mass.
