Pancreas scintigraphy with 75selenomethionine, pancreocimine-secretin test and selective abdominal angiography was carried out in patients with chronic pancreatitis, pancreas carcinoma and subjects without any pancreas diseases. Scintigraphic changes in pancreas were found in 95.6 per cent of the patients with chronic pancreatitis (136 patients) in 92 per cent of them with pancreas carcinoma (25 patients) and in 53.4 per cent from the subjects without pancreas diseases (30 examined). Pathological changes in pancreatic secretion was found in 93.4 per cent of the patients with chronic pancreatitis (105 patients) in 93.8 per cent of the subjects with pancreas carcinoma (32 patients) and only in 3.3 per cent from the examined without pancreatic diseases. The angiographic examination is informative mainly in case of tumours and cysts of the pancreas. The diagnostic potentialities of the separate methods for pancreas examination were critically assessed. The basic diagnostic problems, in pancreas diseases are solved to a great extent with the combined examination with scintigraphy, pancreocimine-secretin test and angiography (76 patients).

We sought to identify characteristics of peptidergic innervation that altered in patients with chronic pancreatitis. Pancreatic tissue removed from patients with chronic pancreatitis was analyzed by immunohistochemistry using antisera against neuropeptide Y, tyrosine hydroxylase, vasoactive intestinal polypeptide, peptide histidine isoleucine, calcitonin gene-related peptide, and substance P, respectively. In accordance with recent findings, the number and diameter of intralobular and interlobular nerve bundles were found to be increased as compared with control pancreas from organ donors. The striking change in the peptidergic innervation pattern in chronic pancreatitis concerned these altered nerves. It consisted of an intensification of the immunostaining for calcitonin gene-related peptide and substance P in numerous fibers contained in these nerves. Adjacent sections showed that immunoreactive substance P and immunoreactive calcitonin gene-related peptide coexisted in these fibers. Because both of these peptides are generally regarded as pain transmitter candidates, our findings provide further evidence that changes in pancreatic nerves themselves might be responsible for the long-lasting pain syndrome in chronic pancreatitis.

In this study, the effects of chronic water immersion stress on the pancreas were investigated in four groups of rats (each group, n = 9): stress + cerulein group, stress group, cerulein group, and control group. Stress + cerulein rats were treated with water immersion stress for 5 h and two intraperitoneal injections of 20 micrograms/kg body wt of cerulein once a week for 16 weeks. In the macroscopic findings of the pancreas, all rats in the stress+cerulein group exhibited moderate or distinctive congestion of blood vessels, gland atrophy, and fatty changes, while some of them showed bleeding. Microscopically, they all exhibited moderate or severe fibrosis, inflammatory cell infiltration, fatty changes, destruction of lobular architecture, and hemosiderin deposits, while some of them also showed bleeding. The stress group without treatment with cerulein injections showed slight fibrosis, hemosiderin deposits, and bleeding. The cerulein group without stress treatment showed fatty changes, but no inflammatory cell infiltration or fibrosis. In the stress + cerulein group only, the contents of digestive enzymes and protein in the pancreas were approximately 55% lower than those of the control group, whereas those in other groups did not show significant reduction. These findings suggest that stress plays some role in the development of chronic pancreatitis, perhaps by causing circulatory disturbance and blood vessel injury.

Pancreas function, lipid peroxidation and antioxidant defence were studied in 154 children aged 1 to 14 years with food allergy. Allergic inflammation due to food allergy favours the origin of different abnormalities of pancreas function: functional (39.4%), reactive pancreatitis (31.3%), chronic pancreatitis (20.1%), and sclerosing chronic pancreatitis (9.2%). They occur in combination with lipid peroxidation activation and a decrease in antioxidant defence. The intensity of the latter ones is dependent on the variety of pancreas function disturbance. The most significant changes in lipid peroxidation and antioxidant defence were discovered in chronic pancreatitis.

Pancreatic tissue obtained from 26 patients with alcoholic chronic pancreatitis (ACP), nine patients with nonalcoholic idiopathic chronic pancreatitis (NAICP), and seven patients with obstructive chronic pancreatitis (OCP) was studied in an attempt to determine whether clinical or etiologic differences have a morphologic counterpart. Histologically it was easy to distinguish ACP from OCP occurring distal to an obstruction of the pancreatic duct. Nine patients with NAICP showed histological features similar to those found in ACP. Plugs and calcifications were found as frequently in NAICP as in ACP, suggesting that NAICP, whatever the etiology, is truly pancreatolithiasis, which leads to slowly progressive fibrosis and acinar atrophy in the obstructed pancreatic lobule. Nerve fibers were found to be more numerous in all disease categories. Inflammatory foci of lymphocytes associated with nerves were observed in 57 and 35% of cases with OCP and ACP, respectively, but only in one patient with NAICP. These findings may constitute a pathological basis for the existing clinical data showing that NAICP frequently runs a pain-free course.

The frequency of diabetes is much higher in tropical calcific pancreatitis (TCP) as compared with alcoholic chronic pancreatitis. We report 97 patients with tropical calcific pancreatitis and compare the profile of 21 patients without diabetes (called TCP for the purpose of this report) with that of 76 patients with diabetes, called fibrocalculous pancreatic diabetes (FCPD) according to the World Health Organization (WHO) study group classification of diabetes. TCP patients were a decade younger and had marginally higher body mass indices (BMIs) as compared with the FCPD group. Of the TCP patients, 13 had abnormal glucose tolerance tests (GTT) and the others had normal GTT. Immunoreactive insulin (IRI) responses to glucose load in the TCP group did not differ significantly from that of the control group. This study shows the existence of early stages of glucose intolerance in TCP.

A 68-year-old woman with papillary adenoma of the pancreas with excessive mucin secretion is reported. The patient was initially diagnosed as having chronic pancreatitis because of a history of repeated attacks of pancreatitis and localized dilatation of the main pancreatic duct. Four years later, endoscopic retrograde pancreatography showed markedly diffuse dilatation of the entire main pancreatic duct with amorphous filling defects of mucin. Excretion of mucin was observed through the enlarged orifice of Vater's ampulla. The patient was treated with distal pancreatectomy, and papillary adenoma with abundant mucin in the cytoplasm was histologically demonstrated. We describe unique clinical features of "mucin-producing pancreatic tumor" and discuss an important role of endoscopic retrograde pancreatography in the diagnosis.

In a comparative study of tropical chronic pancreatitis (TCP) and alcoholic chronic pancreatitis (ACP) occurring in the same population, we analyzed the clinical profile of 50 patients of ACP seen over the past 3 years at our centers and compared this with the profile of our TCP patients. A majority (75%) of patients in both groups belonged to Tamil Nadu and 90% had never consumed cassava. Whereas TCP occurred in young subjects of both sexes, ACP patients were all males and presented at an older age. The frequency of pain, diabetes, and pancreatic calcification was similar in the two groups. Patients in both groups were lean, but signs of severe malnutrition were rare. Prediabetic patients had normal body mass index. There were striking differences in radiological appearance of pancreatic calculi in TCP and ACP. Malignancy of the pancreas was present in three patients with TCP. Benign bile duct stenosis was seen in three patients with ACP but not in TCP. Compared to ACP seen in the West, our ACP patients had a shorter duration of symptoms in spite of having advanced disease. TCP and ACP have distinct clinical profiles and it is possible that some environmental factors may hasten the progress of ACP in the tropics.

The expression of six sialylated carbohydrate antigens (CA19-9, CA-50, SLEX, SLX, DU-PAN-2, ST-439) was examined in malignant and nonmalignant pancreatic tissues using an immunohistochemical method to elucidate the characteristics of these carbohydrate antigens as tumor markers. All carbohydrate antigens except for sialyl SSEA-1 (SLX, 52.4%) were expressed in more than 80% of the pancreatic cancer. CA19-9 and CA-50, belonging to type I blood group antigens, and DU-PAN-2 and ST-439 were localized predominantly in the cytoplasm of cancer cells, while sialyl Lex (SLEX) and SLX, belonging to type II blood group antigens, were stained mainly on the apical membranes of malignant glands. Although type I antigens were expressed in most nonmalignant pancreatic tissues, the type II antigens and ST-439 were absent in almost all of the normal tissues and faintly expressed in few chronic pancreatitis tissues, suggesting the high tumor specificity of these antigens. Each antigen was expressed on the apical surface of ducts in normal pancreas. However, in about 30% of chronic pancreatitis cases, type I antigens and DU-PAN-2 were observed in the cytoplasm of ductal cells. All patients showing stromal stain, possibly caused by loss of antigen polar expression and shedding into the surrounding stroma adjacent to malignant glands, revealed high levels of serum antigen. This finding suggests that the stromal appearance of antigens is a significant factor in the elevation of serum antigen levels.

Fecal isoamylase activity was studied in 93 consecutive patients (26 in the recovery stage of acute pancreatitis, 24 with chronic pancreatitis, 13 with pancreatic cancer, and 30 with other gastrointestinal diseases) and compared with fecal chymotrypsin activity and the results of the secretin test. Seventy-six healthy subjects were studied as controls. Both pancreatic (p)-type and salivary (s)-type isoamylase activities in stool were determined by inhibitor assay as well as cellulose acetate electrophoresis. The mean fecal amylase activity in healthy subjects was 757 +/- 88 IU/g (p-type isoamylase: 77 +/- 2%, s-type isoamylase: 23 +/- 2%). There was a good correlation between fecal p-type isoamylase and chymotrypsin activities (r = 0.625, p less than 0.001). Fecal p-type isoamylase activity in patients with chronic pancreatitis and pancreatic cancer was significantly lower than in healthy subjects (p less than 0.001). Patients with moderate and severe exocrine pancreatic insufficiency as determined by the secretin test had significantly lower fecal p-type isoamylase activity. Daily fat intake did not affect fecal amylase or isoamylase activities. Fecal s-type isoamylase activity in patients with hypoacidity was significantly higher than in patients with hyperacidity, but no difference in fecal p-type isoamylase activity was observed. It is concluded that analysis of fecal isoamylase activity is useful in the assessment of pancreatic function.
