Outline of Final Research Achievements

Chronic pancreatitis is an inflammatory disorder, causing a progressive and irreversible dysfunction of exocrine and endocrine pancreas. Recently, leptin receptor-deficient WBN/Kob-Fatty (WKF) rat was developed for a model of chronic pancreatitis and diabetes with obesity. The purpose of this study was to investigate whether chronic exercise with restricted diet improved the exocrine and endocrine pancreas of WKF rats.
Male 12wks WKF rats had symptoms of pancreatitis and diabetes (hyperglycemia, hyperlipidemia, insulin resistance, fatty pancreas, inflammation, morphological abnormality), but WK rats did not. These results indicated that obesity was a major factor to aggravate pancreatitis and diabetes. Chronic exercise with restricted diet beneficially affected the exocrine and endocrine pancreas in WKF rats through the treatment of obesity.
Pancreatic dysfunction of chronic pancreatitis and diabetes may be improved by adequate exercise habit with restricted diet.
