Serum gastrin increased in patients with pernicious anaemia after a beef-meal, but decreased after an oral load of glucose, xylose or sodium chloride. 50 g of glucose and 25 or 75 g of xylose suppressed serum gastrin to approximately 40% of basal values at 60 min and were slightly more effective than 10 g of sodium chloride. There was no rise in beef-meal stimulated serum gastrin concentration in vagotomized patients and only a slight rise in two patients with duodenal ulcer when an oral dose of 10 g of sodium chloride was given together with the beef-meal. 25 g of xylose suppressed basal serum gastrin concentration significantly in six vagotomized patients. Nasal administration of small amounts of vasopressin decreased basal serum gastrin significantly in six vagotomized patients. Nasal administration of small amounts of vasopressin decreased basal serum gastrin significantly in all subjects examined. Further studies indicated, however, that vasopressin was only effective when pharmacological plasma concenten orally and intraduodenally were compared in six patients with pernicious anaemia. Serum gastrin concentration decreased approximately to the same extent in both experiments. It is concluded that the inhibitory effect of glucose on gastrin secretion most likely is mediated hormonally via osmo-receptors located in the small intestine.

The thymus is a central lymphatic organ that is responsible for many immunological functions, including the production of mature, functional T cells and the induction of self-tolerance. Benign or malignant tumors may originate from the thymus gland, with thymoma being the most common and accounting for 50% of anterior mediastinal tumors. Malignancies linked to thymoma include the loss of self-tolerance and the presence of autoimmunity. In this review, we compiled the current scientific evidence detailing the various interactions between thymoma and autoimmune diseases, including myasthenia gravis, systemic lupus erythematosus, inappropriate antidiuretic hormone secretion, pure red cell aplasia, pernicious anemia, pemphigus and autoimmune thyroid diseases. In recent years, several mechanisms have been proposed to explain these interactions. Most are based on the assumption that the 'sick' thymus, like the 'normal' thymus, can generate mature T cells; however, the T cells generated by the sick thymus are impaired and thus may exert cellular autoreactivity. Here, we present several theories that may shed light on the loss of self-tolerance associated with this epithelial tumor of the thymus.
