We examined diurnal changes of pancreatic exocrine secretion and plasma levels of cholecystokinin (CCK) and human pancreatic polypeptide (hPP) in men with postoperative transient external pancreatic drainage (3 with pancreatico-jejunostomy: PJ, and 5 with pancreato-duodenectomy:PD). Plasma CCK levels increased and the pancreatic exocrine secretion showed a corresponding increase after meals in both groups. In the PJ group hPP levels increased after meals and there was a significant correlation between the plasma levels of CCK and hPP. In the PD group the plasma hPP levels were not detectable throughout the study and there was a better correlation between the exocrine secretion and the plasma CCK levels than in the PJ group. Plasma CCK levels showed rhythmic changes associated with pancreatic exocrine secretion, with no significant changes in plasma glucose and insulin in the night (24:00-07:00). These results suggested that (1) the resection of the pancreatic head which is rich in hPP contents led to a complete loss of anti-CCK effects on CCK, and that (2) fluctuation in plasma CCK levels, in the fasting state, might initiate pancreatic exocrine secretion.

UI MeSH Term Description Entries
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D010179 Pancreas A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
D010190 Pancreatic Neoplasms Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).

D010191 Pancreatic Polypeptide A 36-amino acid pancreatic hormone that is secreted mainly by endocrine cells found at the periphery of the ISLETS OF LANGERHANS and adjacent to cells containing SOMATOSTATIN and GLUCAGON. Pancreatic polypeptide (PP), when administered peripherally, can suppress gastric secretion, gastric emptying, pancreatic enzyme secretion, and appetite. A lack of pancreatic polypeptide (PP) has been associated with OBESITY in rats and mice. Pancreatic Polypeptide (PP),Pancreatic Polypeptide Hormone,Pancreatic Prohormone
D010195 Pancreatitis INFLAMMATION of the PANCREAS. Pancreatitis is classified as acute unless there are computed tomographic or endoscopic retrograde cholangiopancreatographic findings of CHRONIC PANCREATITIS (International Symposium on Acute Pancreatitis, Atlanta, 1992). The two most common forms of acute pancreatitis are ALCOHOLIC PANCREATITIS and gallstone pancreatitis.

D002766 Cholecystokinin A peptide, of about 33 amino acids, secreted by the upper INTESTINAL MUCOSA and also found in the central nervous system. It causes gallbladder contraction, release of pancreatic exocrine (or digestive) enzymes, and affects other gastrointestinal functions. Cholecystokinin may be the mediator of satiety.

D002908 Chronic Disease Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).
