[Hormonal changes shortly after surgery in patients operated for stomach ulcer]

The content of gastrin, pituitary thyrotropin hormone (TTH), the thyroid hormones thyroxin (T4) and triiodothyronine (T3), and 11-OCS in blood serum and the daily catecholamine content in urine were studied in 86 patients in the early periods, 2-4 weeks, after resection of the stomach or selective proximal vagotomy (SPV). The content of gastrin, TTH, T4, and 11-OCS in blood was reduced and catecholamine excretion diminished in patients after gastric resection. After SPV the concentration of gastrin increased and that of TTH reduced. A certain relationship between the clinical course of peptic ulcer and the indices studied was revealed. The application of rehabilitation measures in the early periods after operations on the stomach improves the neuroendocrine regulation in the organism and the functional condition of the alimentary organs.
