Serum gastrin concentration before and after parietal cell vagotomy in man and dog.
Serum gastrin concentrations were measured during fasting and after feeding in duodenal ulcer patients and in dogs before and after parietal cell vagotomy (PCV). Postoperatively, fasting serum gastrin concentrations increased significantly in man and insignificantly higher in dog. After feeding, serum gastrin reached higher values postoperatively in both man and dog. The percentage rise in food-stimulated serum gastrin after PCV was higher in dog than in man.
