Abstract/OtherAbstract:
The present report describes the long-term effects of antrectomy, antrum exclusion, portacaval shunt, omeprazole treatment, or the combination of omeprazole treatment and portacaval shunt on the number and density of somatostatin cells in the oxyntic mucosa of the rat. Antrectomy, which is associated with hypogastrinemia, raised the number and density of the somatostatin cells, whereas antrum exclusion and omeprazole treatment, which are associated with hypergastrinemia, reduced the number and density of the somatostatin cells. Portacaval shunt, which is associated with hypogastrinemia, increased both the number and the density. Omeprazole treatment of portacaval--shunted rats suppressed or even reversed the somatostatin cell hyperplasia after portacaval shunt alone. From these findings it is unlikely that gastrin stimulates the proliferation of somatostatin cells in the oxyntic mucosa. In fact, there seems to be an inverse relationship between the serum gastrin concentration and the somatostatin cell number.
