    Notes: Abstract 1. The effects of graded intravenous doses of cholecystokinin (CCK) and caerulein on exocrine pancreatic secretion have, been assessed in conscious rats. Bile and pancreatic juice were separately returned to the duodenum between and during tests. 2. Low doses of CCK (from 417 to 3,335 ng kg−1 h−1) or caerulein (from 37.5 to 150 ng kg−1 h−1) slightly increased flow rate but increased K+ and HCO 3 − outputs to a greater extent, without altering Cl− output. The sum of the anion concentrations (Cl−+HCO 3 − ) stayed constant, which explains the decrease in Cl− concentration when the HCO 3 − concentration increased. 3. High doses of CCK (6,670 and 13,335 ng kg−1 h−1) and of caerulein (600 ng kg−1 h−1 strongly inhibited volume flow and outputs of all the ions, and the sum of the concentrations of anions fell. 4. Protein concentration and output increased with the same time course in response to both CCK and caerulein, i. e. course in response to both CCK and caerulein, i. e. a sustained stimulation during infusion, without any delayed inhibitory effect afterwards. The increase followed a linear dose-response relation to both CCK and caerulein. D50 was approximately 1,000 ng kg−1 h−1 for CCK and 95 ng kg−1 h−1 for caerulein. The maximal secretory rate of protein in our experiments was obtained with 300 ng kg−1 h−1 caerulein (20.27 mg 30 min−1) and was almost twice that obtained with CCK (10.6 mg 30 min−1) which suggests that the most potent agonist is a shorter derivative of CCK. Finally, both hormones decreased protein output at supramaximal levels. 5. It is concluded that both CCK and caerulein have similar effects on pancreatic secretion in the conscious rat and in other species. However, the conscious rat differs from other species in that water, HCO 3 − and K+ secretions are stimulated by low doses of agonists. In contrast, high doses of agonists inhibited all components of secretion.

    Notes: Summary A statistical study of 98 patients with pancreatitis leads us to think that the “monist” conception of “recurrent chronic pancreatitis”—according to which the noncancerous pathologic change is confined to a single affection that either may kill at the first attack (hemorrhagic pancreatitis) or be repeated and slowly lead to sclerosis and, later, endoductal calcification—neglected the true facts in favor of a too rigorous classification. Among the affections which the anatomicoclinical method has permitted us to isolate, a particularly serious form of chronic pancreatitis is to be noted: “primary inflammatory sclerosis.” It appears in later life (average age of onset, 61.4 years) and is found as often in women as in men; in most cases it progresses to cachexia and death. The relatively long duration of the evolution makes certain small, slowly developing duodenal or pancreatic cancers complicated by distal pancreatitis the only condition that need be considered in the differential diagnosis. Both clinical evolution and anatomic aspect are marked by significant signs of inflammation. Despite repeated attempts, no germ has been discovered. It is thus possible to put forward the hypothesis that this type of pancreatitis is an inflammatory, noninfectious disease that is caused by phenomena of self-immunization.

    Notes: Abstract A group of 101 female patients with gallstones were compared to 101 agematched controls. The patients with gallstones had a statistically significant (p=0.0005) increased intake of calories, irrespective of dietary composition. Psychologic stresses were more frequent in patients with gallstones (p〈0.001); the following factors were not significantly different in the two groups: body weight, working conditions, and physical exercise.

    Notes: Conclusions Studies on bile composition with respect to diet, quantity, and composition have been carried out. The composition of Ttube bile has been studied in a group of patients having cholecystectomy for cholelithiasis, and a group of patients having cholecystectomy for other reasons. Our studies suggest that the formation of cholesterol gallstones is related to two factors: (1) An increase in biliary cholesterol concentration when caloric and daily protein intake increases and (2) an increased intake of calories irrespective of diet composition. The in-vitro conditions for precipitation and solubilization of biliary cholesterol are now rather well established. In addition, the changes in biliary cholesterol, bile salts, and phospholipid concentration may be studied under defined experimental conditions. Our studies suggest that the bile of patients with cholelithiasis has a composition from time to time which is favorable for the formation of gallstones. The variations in bile composition appear to be dependent upon the diet: the greater the caloric intake, the more frequently will bile have a composition which favors cholesterol precipitation.

    Notes: Abstract One hundred nineteen children, either French or from the Ivory Coast, aged 1–8 years, were submitted to pancreatic function testing by duodenal aspiration. Trypsin, chymotrypsin, lipase, phospholipase, amylase, volume, bicarbonate, chloride, and calcium were estimated before and after an intravenous injection of 1 CU secretin+3 CHR units pancreozymin per kilogram of body weight. Sixty-two patients were normal European children, and 11 were normal African children. Twenty-five African children presented with kwashiorkor and 10 African children had presented with kwashiorkor but had recovered at the time of the test. Three cases of recurrent kwashiorkor are also included. In the normal group of African children, phospholipase concentration, volume, and bicarbonate were significantly decreased but chymotrypsin and trypsin connentrations were not, when compared to the normal European population. In kwashiorkor patients, lipase, amylase, phospholipase, and chymotrypsin concentration were significantly decreased compared to normal Africans. Trypsin, volume, and bicarbonate were not affected. These modifications disappeared after refeeding. In cases of recurrent kwashiorkor, all enzymes, including trypsin, were decreased. Calcium was never modified. These modifications were very different from those observed in chronic alcoholic and hypercalcemic pancreatitis. In a two-year study, chronic calcifying pancreatitis (CCP) was diagnosed in 14 patients (13 males), hospitalized in Abidjan. The mean age at onset of the disease was 41 years (sd 12.71), which is very similar to European cases. The most frequent cause was alcoholism, as in Occidental countries. The nutrition of the population was low in protein, calories being provided mostly by manioc, but no apparent symptoms of malnutrition were observed in the parents of our patients. It is concluded that: the pancreatic insufficiency due to kwashiorkor is reversible, trypsin is more resistant to malnutrition than other enzymes, there is no apparent relationship between kwashiorkor and tropical form of CCP, and manioc consumption is apparently not a cause of CCP.

    Notes: Abstract This is a critical review of papers published on definition, classification, etiology, and pathogenesis of chronic pancreatitis from 1981 to 1985. Articles published earlier will only be mentioned when they are necessary to the understanding of the present knowledge or when they are insufficiently known. The more ancient literature has been reviewed elsewhere (1–3). The etiology and pathogenesis section will be limited to calcifying pancreatitis which is the most frequent form of chronic pancreatitis. The etiology of chronic obstructive pancreatitis has been studied in another review (2). The simple fibrosis of the pancreas is excluded from this chapter (4).

    Notes: Abstract The effects of intragastric and intravenous ethanol administration on exocrine secretion of human pancreas were studied in 15 subjects. By either route, ethanol administration substantially reduced volume, concentration and output of bicarbonates, lipase and chymotrypsin. This action is interpreted as direct inhibition of the pancreas by ethanol. However, calcium concentration in duodenal juice increased with intragastric ethanol administration and decreased with intravenous ethanol administration.
