The authors investigated the activity of Kikyo-to on the intestinal hormones, cholecystokinin (CCK) and secretin, released in healthy humans. The clinical efficacy of Kikyo-to on the abdominal symptoms associated with chronic pancreatitis was also investigated. In healthy volunteers, Kikyo-to (5g) significantly increased plasma CCK and secretin concentrations 30 minutes after treatment. In chronic pancreatitis patients, abdominal pain, abdominal tenderness, nausea and diarrhea were decreased by treatment with Kikyo-to (7.5g/day; divided into three doses). In conclusion, Kikyo-to improved the complaints of chronic pancreatitis, especially abdominal pain. The presumed mechanism was that Kikyo-to stimulated pancreatic exocrine secretion by the release of intestinal hormones, CCK and secretin.

Based on two years working of “the enlarged working group for the curriculum of chemistry for medical education”, a provisional plan of the curriculum of chemistry for medical students is proposed. The article is consist of four sections; namely A: general problems, B: “chemistry” as a general education, C: purpose and specific problems of the general education for medical students, D: a provisional plan of the curriculum of chemistry for medical students.
The main part D is consist of three subsections: namely (1) a plan of the curriculum of physical and inorganic chemistry, (2) a plan of the curriculum of organic chemistry, (3) a plan of the curriculum of experiments.
