The promoted condition of the remnant stomach was examined in rats after oral administration of MNNG, using measurement of Ornithine Decarboxylase(ODC) activity of four groups, each of which were performed with the Billroth I method, the Billroth 11 method with/without Braun's anastomosis or gastrectomy as the control. ODC activity in the remnant stomach after each three types of operation was significantly high as compared to that in the stomach after the gastronomy. Guanosine Triphosphate(GTP) activated ODC activity after the Billroth 11 method without Braun's anastomosis was significantly higher than that of the other three groups. In conclusion, it was considered that the remnant stomach was under the highly promoted condition, especially after the Billroth 11 method without Braun's anastomosis.
