Abstract
Ultrastructural study of mucosal eosinophils in a case of eosinophilic gastroenteritis involving stomach, duodenum and ileum showed an altered structure in ulcerated duodenal areas. The electron core density of eosinophil granules was inverted or disappeared and tubulovesicular structures occurred. Using immunogold staining with specific antibodies, major basic protein was detected diffusely in the matrix of eosinophil granules and out of the granules in tight association with extragranular membrane formations. In contrast, eosinophil cationic protein and eosinophil peroxidase were normally distributed in the granule matrix. When compared with the eosinophils in macroscopically normal duodenal mucosa in the same patient, these changes support a role for major basic protein in tissue damage in eosinophilic gastroenteritis. The diffusion of one granule protein from the granules to the exterior of the cells favours the view of a selective release of eosinophil mediators.

Abstract
We applied sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and immunoblotting to analyze fecal alpha 1-proteinase inhibitor (alpha 1 PI) from healthy subjects and patients with Crohn's disease. A component with Mr 38,000 was characterized in normal fecal extracts as well as in six pathological samples. In these cases, the Crohn's disease activity index (CDAI), a clinical index of severity of the disease, was 170 (SEM 47). In contrast, alpha 1 PI of Mr 51,000 was detected in fecal extracts from eight patients with active Crohn's disease (CDAI = 287, SEM 39). We conclude that fecal alpha 1 PI can be considered a marker of intestinal disease activity.

Abstract
A 29-yr-old Tunisian man had a clinical immunoproliferative small intestinal disease, different from alpha-chain disease. Serum contained 52.5 mg/ml of polymeric immunoglobulin A (IgA). Immunohistochemistry revealed a massive diffuse polyclonal IgA (99%)-plasma cell infiltration in the small bowel mucosa, with a smaller increase of IgA-producing cells in gastric and colonic mucosae. Secretory IgA levels were normal in jejunal and bronchoalveolar secretions. However, both fluids contained polymeric IgA devoid of secretory component, and free secretory component was absent. This suggests that secretory component was the limiting factor in transport of IgA in the secretions. A relative deficiency in secretory component, as compared with the huge supply of polymeric IgA, may have limited the secretory component-mediated active transport of IgA into secretions. This resulted in the appearance of high levels of polymeric IgA, unlinked to secretory component, both in serum and in the jejunal and bronchoalveolar fluids.

Abstract
The aim of this study was to measure the role of the duodenal loop in biliopancreatic secretion in man by infusing various stimuli at the ampulla of Vater and collecting duodenal contents at the ligament of Treitz, above an occluding balloon. Perfusion at 10 ml/min of a first mixture of aminoacids - phenylalanine (47.2 mmol), methionine (38.2 mmol), tryptophan (11 mmol), valine (61.6 mmol) - increased cholecystokinin (CCK) plasma concentrations and duodenal bile salt output (p less than 0.005) as compared with a control electrolyte solution, but did not change pancreatic enzyme secretion significantly; duodenal infusion of another aminoacid mixture - arginine (32.4 mmol), histidine (14.1 mmol), leucine (36 mmol), isoleucine (21.5 mmol), lysine (31 mmol), threonine (23 mmol) - did not change CCK plasma concentrations, bile salt or pancreatic enzyme output. The respective role of duodenal distension and endogenous CCK was investigated by perfusing the first aminoacid solution and the control solution at 2, 5, and 10 ml/min. Changing the perfusion rate of control solution from 2 to 5 ml/min led to a significant increase (p less than 0.01) in pancreatic secretion with no further increase at 10 ml/min. Bile salt output was not influenced by the perfusion rate of control solution. During the perfusion of the aminoacid solution, despite a stepwise increase in CCK release, the only significant change in pancreatic secretion was an increase of lipase output (p less than 0.05) when the infusion rate was raised from 2 to 5 ml/min. Our results suggest that duodenal CCK release (1) depends on the nature of aminoacids (2) has predominant role in the regulation of pancreatic secretion at low perfusion rate but is less effective when superimposed on a mechanical stimulus caused by duodenal distension (3) is a major stimulus for gall bladder contraction which is not influenced by duodenal distension.

Abstract
Histochemical and electron microscopic examinations of the liver were performed in 5 adults receiving parenteral nutrition for greater than 18 mo and in 4 adults receiving parenteral nutrition for less than 5 mo. Phospholipidosis, reflected by the presence of cytoplasmic phospholipid deposits at histochemical examination and the presence of multilamellar lysosomes at electron microscopy, was marked and present in hepatocytes, Kupffer cells, and portal macrophages in all 5 patients receiving parenteral nutrition for greater than 18 mo. Mild phospholipidosis, affecting only hepatocytes, was demonstrated in 3 of the 4 patients receiving parenteral nutrition for less than 5 mo. These findings indicate that liver phospholipidosis is relatively common in patients receiving parenteral nutrition and that the degree of liver phospholipidosis depends on the duration of parenteral nutrition. Liver phospholipidosis might be due to intrahepatic accumulation of intravenous phospholipids provided by fat-emulsion sources.

Abstract
A previously healthy 50-year old man presented with acute small bowel obstruction. No etiology was found at laparotomy. Postoperatively, the patient remained symptomatic with nausea, vomiting and severe constipation. Gastroscopy revealed retained food in the stomach. Gastric emptying of solids and liquids was dramatically decreased at scintigraphy. The colon was dilated on X-ray study. Chest X-ray revealed a pneumopathy and a small-cell lung cancer was discovered at bronchoscopy. The patient died 5 months after onset. Histologic study of the gut showed widespread degeneration of the myenteric plexus with plasma cell infiltration, Schwann cell proliferation and a reduced number of neurons of which many were abnormal. Intestinal pseudo-obstruction can reveal a small-cell lung cancer; the mechanism of neuronal impairment leading to pseudo-obstruction remains unknown, but could be related to the pathophysiology of paraneoplastic syndromes.

Abstract
The aim of this work was to study the role of gut associated lymphoid tissue in the control of bacterial translocation. Two strains of Escherichia coli were orally inoculated to 71 axenic mice. Ten days after, the 2 initial strains and 2 others, resulting from plasmidic exchanges, were present in the digestive tract of the mice which were divided in two groups: the first group (n = 41) received one intraperitoneal injection of cyclophosphamide 100 mg/kg; the second control group (n = 30) received isotonic saline. The following parameters were studied 3, 5 and 9 days after the injection: the population level of the 4 strains in the caecum, their translocation to mesenteric lymph nodes, liver, spleen and circulating blood, the density per unit surface of lamina propria plasma cells and intraepithelial lymphocytes in duodenal and caecal mucosae. The population in each strain found in the caecum was different from the 3 others but similar within the two groups of animals and remained unchanged with time. In the control group, bacterial translocation to the mesenteric lymph nodes decreased (p less than 0.01), while the density of plasma cells increased (p less than 0.01) from the 3rd to the 9th days. In the cyclophosphamide treated group, translocation to the mesenteric lymph nodes increased (p less than 0.01), while the density of intestinal plasma cells decreased (p less than 0.05) from the 3rd to the 9th days. Density of intraepithelial lymphocytes did not vary with time in each group and from one group to another. Bacterial translocation to liver, spleen and systemic blood was weak and did not increase in the treated group.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We have investigated the following pulmonary related parameters in 22 patients with Crohn's disease who were free of clinical pulmonary symptoms and had normal chest roentgenograms and in 25 controls: serum angiotensin converting enzyme, pulmonary function tests, bronchoalveolar lavage (lymphocyte count and subpopulations, macrophage viability and superoxide anion release by macrophages) and pulmonary scannings. Serum angiotensin converting enzyme was lower in Crohn's disease (14.1 +/- 5.1) than in controls (25.2 +/- 4.7) (p less than 0.001). Twelve of 22 Crohn's disease (54%) had a bronchoalveolar lavage lymphocytosis (greater than 18% alveolar lymphocytes). Bronchoalveolar lavage lymphocytes subpopulations were quite variable. Twelve of 17 Crohn's disease (71%) had an increase spontaneous and/or stimulated superoxide anion production by alveolar macrophages. Six of 12 Crohn's disease (50%) had an increase physiologic dead space in the upper part of their lung against one of 11 controls (9%). These data suggest that most patients with Crohn's disease have a latent pulmonary involvement.

Abstract
Cellular characteristics of bronchoalveolar lavage (BAL) were investigated in 18 consecutive patients with Crohn's disease, who were free of clinical pulmonary symptoms and had normal findings on chest roentgenograms. Total BAL cell count and cellular viability of alveolar macrophages did not differ significantly between patients and control subjects. Percentage of alveolar lymphocytes was increased in 11 of 18 patients (from 18 percent to 79 percent). There was no apparent correlation between BAL differential cell count and abnormal pulmonary function tests noted in 11 patients, drug treatment or Crohn's disease site, and activity. These results demonstrate a high proportion of latent lymphocyte alveolitis as assessed by BAL, suggesting a latent involvement of the lung in Crohn's disease.

Abstract
Gastric metastases of choroid malignant melanoma seem to be exceptional since less than 10 cases have been previously published. We report the case of a 71 year old patient with a gastric melanosarcoma secondary to a choroid malignant melanoma. Gastric metastasis was revealed by digestive bleeding occurring 18 years after right eye enucleation. Gastroscopy showed black ulcerated tumors. Histology confirmed the diagnosis portraying typical melanic pigments within the gastric mucosa. Laser photocoagulation of the gastric lesion was used for the first time in this indication. As a result, hemorrhage decreased and the patient's comfort was improved.
