Plasma Gastrin Concentraion after Ingestion of Sesame Gruel in Normal Human Subjects

깨죽이 정상 성인의 혈장 Gastrin 농도에 미치는 영향

This study was conducted to investigate the effect of ingestion of sesame (Sesamum indicum) gruel as a nourishing meal upon the plasma gastrin concentration in normal Korean. Sixteen normal persons with no history of gastrointestinal diseases, including male and female were studied. After an overnight(about 15 hrs) fast, eight persons(mean age: 26.6, range: $20{\sim}40$ years) of them ingested a 350 ml sesame gruel corresponding to 12 g protein, 13 g fat and 99 g carbohydrate, and the remaining 8 subjects(mean age: 21.3, range: $20{\sim}24$ years) ingested a 350 ml glutinous rice gruel(control meal) corresponding to 8 g protein, 1 g fat and 115 g carbohydrate. The venous blood samples were drawn before and after the ingestion of the test meal for the measurement of gastrin by means of radioimmunoassay. 1) Plasma gastrin concentration in response to the ingestion of sesame gruel or glutinous rice gruel increased significantly compared with the concentration in fasting state. 2) Mean increment or percent increment in postprandial plasma gastrin concentration after the ingestion of sesame gruel was not significantly different from that after the control meal, i.e. the glutinous rice gruel. It is inferred from the above results that the ingestion of sesame contained in sesame gruel may have no significant influence on gastrin release in normal human subjects.
