Outline of Final Research Achievements

At first, we investigated Ghrelin and GLP-2 level in 80% small bowel resection (80% SBR) rat model. The major findings of this study are as follows (1) Acyl ghrelin and des-acyl ghrelin levels increased immediately, equivalently in both operation groups. (2) In 80% SBR animals, ghrelin peaked on day 4. GLP-2 secretion was obvious in 80% SBR animals, which increased immediately and peaked on day 4. (3) Morphological adaptations were evident after day 4.
Then, we investigated the effect of ghrelin administration for intestinal mucosal atrophy induced by total parenteral nutrition (TPN) using rat model. The major findings of this study are as follows (1) TPN for 6 days induced mucosal atrophy was recognized in jejunum greater more severe than in ileum. (2) Administration of ghrelin improved mucosal atrophy in TPN rat model. (3)There were no significant changes in body weight or small bowel weight.
