Portions of duodenum, jejunum, and ileum from 21 hamsters clinically affected with enteritis were examined for enzymes. Utilizing a variety of techniques, the activities of alkaline phosphatase, nonspecific esterases, leucine aminopeptidase, beta-glucuronidase, and methyl green pyroninophilia were determined. The activities of enzymes normally associated with tissue proliferation and active protein synthesis were decreased, whereas those enzymes associated by cytolysis were increased.

Abdominal eumycotic mycetoma caused by Pseudallescheria boydii was diagnosed in a 3-year-old male Siberian Husky. The dog was examined because of weight loss and signs of depression. Initially, pyrexia was the only clinical finding. Antibiotic and corticosteroid treatment was ineffective. Two weeks later, the dog's appetite had decreased, it had vomited a few times, and the caudal portion of the abdomen was sensitive to palpation. Hematologic and serum biochemical abnormalities consisted of anemia, leukocytosis, hypoglycemia, hypoalbuminemia, hyperglobulinemia, and high alkaline phosphatase activity. One week later, the dog's condition continued to worsen, and testicular swelling was observed. The dog was castrated. Microscopic examination of specimens obtained at surgery revealed pyogranulomatous periorchitis with mycetoma granules. Ketoconazole treatment was initiated and continued until the dog died one month later. Necropsy revealed multifocal duodenal ulcers, with transmural pyogranulomatous enteritis, pancreatitis, and peritonitis. This case is unique because the etiologic agent apparently entered via the intestinal tract rather than by contamination of an external wound.

Sclerosing cholangitis, an inflammatory disease of the biliary tree that occurs infrequently in childhood, has been recognized in combination with papillary stenosis in adults with the acquired immunodeficiency syndrome. A 10-yr-old child with a familial immunodeficiency syndrome characterized by defective T-cell function and deficiencies of immunoglobulins A and G developed papillary stenosis and sclerosing cholangitis associated with cryptosporidium enteritis. The patient presented with fever, jaundice, right upper quadrant pain, and elevated serum concentrations of transaminases and alkaline phosphatase. The pain and jaundice resolved after endoscopic sphincterotomy, but the biochemical abnormalities persisted. This case demonstrates that the combination of papillary stenosis and sclerosing cholangitis can occur in children as well as adults and may be associated with immunodeficiency syndromes other than the acquired immunodeficiency syndrome. Endoscopic sphincterotomy can provide symptomatic treatment for papillary stenosis in children with this condition, although the effect of sphincterotomy on the natural history of the sclerosing cholangitis is uncertain.

A comparative trial was conducted with the oral administration of zinc sulphate to pregnant cows and heifers aimed at influencing the selected metabolic parameters in the dam-calf line. The total daily ZnSO4.7H2O dose of 3 g (680 mg Zn++) was given to dry standing cows and heifers for 35 days on an average (15-65) before the expected date of calving. The breeding conditions in the stock were problematic: losses of calves suffered in the last half-a-year period were higher than 30% of born calves; the main causes of this high mortality were coli-septicaemia and coli-enteritis. As compared with the eight control animals, the experimental cows and heifers (12 head) exhibited a transient increase in zincaemia, followed by a tendency to proteinaemia; aspartate aminotransferase activity increased, total immunoglobulins remained unchanged, and decreases were recorded in the activities of alanine aminotransferase, alkaline phosphatase, creatine phosphokinase and aldolase. On the other hand, the concentration of total bilirubin tended to increase. In 77% of the cows and first-calvers of the experimental group the quality of colostrum complied with the standard; in the case of the control animals this proportion was 83%. Significant zincaemia occurred in the calves of the experimental cows between the first and 14th day of their age; no differences from the control calves were recorded in immunoglobulinaemia, proteinaemia, albuminaemia and in the activities of alanine aminotransferase and creatine phosphokinase. On the other hand, aspartate aminotransferase activity tended to grow and alkaline phosphatase activity tended to sink. Neonatal hyperbilirubinaemia disappeared within the first 14 days of age in both the experimental and the control calves. The results failed to show clearly that the intention to increase the values of the studied parameters of immunopoiesis was met.

A double antibody sandwich enzyme-immunoassay has been developed for detection of Clostridium perfringens enterotoxin. Anti-enterotoxin immunoglobulin G-alkaline phosphatase conjugates were prepared using a rapid minicolumn procedure. The assay can achieve a sensitivity of greater than or equal to 1 ng/ml with purified enterotoxin. Sensitivity for detection of cases of C. perfringens enteritis in a C. perfringens outbreak (86 individuals tested) was between 85.7 and 98.0 per cent depending upon stringency of criteria for defining positive cases. Specificity of the assay was demonstrated by the lack of positive results in 53 individuals involved in a gastroenteritis outbreak of unknown etiology.

The pathogenesis of Clostridium difficile enterocolitis appears to involve colonization of the bowel followed by release of toxin A, an enterotoxin, and toxin B, a cytotoxin. The purpose of this study was to determine the effect of purified toxins A and B on intestinal secretion, epithelial permeability, and morphology in perfused rabbit ileal loops. Intestinal permeability after toxin exposure was assessed by blood-to-lumen clearance of [3H]mannitol. Toxin A at doses of 5-100 micrograms/10 cm ileal loop caused a threefold to fivefold increase in [3H]mannitol permeability (p less than 0.001) vs. equal concentrations of toxin B or buffer control. In addition, perfusate from toxin A-exposed loops contained significantly more neutrophils (p less than 0.001) than toxin B or control loops. Toxin A caused severe epithelial cell necrosis with destruction of villi and polymorphonuclear infiltration. Electron microscopy of mucosa subjected to a low dose of toxin revealed widespread nonspecific dilatation of endoplasmic reticulum and mitochondrial swelling. In contrast to these effects of toxin A in ileal loops, in vitro experiments with ileal explants in short-term organ culture revealed that toxin A had no effect on epithelial cell permeability, protein synthesis, release of alkaline phosphatase, or morphology. Our results show that purified toxin A but not toxin B causes severe inflammatory enteritis in rabbit ileal loops, but has no discernable effect on rabbit ileum in vitro. We speculate that toxin A may contribute significantly to intestinal damage in C. difficile-associated colitis and diarrhea.

Liver metastases are a common cause of death in colon carcinoma. The dual blood supply of the liver permits regional perfusion while hepatic catabolism fo 5-fluorouracil (FU), floxuridine (FUdR) permit higher drug exposures than systemic (IV) administration. We have studied the effect of continuous intra-arterial chemotherapy (FU: 5-10 mg/kg/day and FUdR: 0.2 mg/kg/day) and whole liver irradiation (1000 rad every 4 weeks, total dose of 3000 rad) for metastatic colon carcinoma to liver. Eighteen patients with metastases to liver only are reported using this combination therapy. Seven patients had percutaneous placement of a catheter via the brachial artery, two had operative placement of a catheter via the gastroduodenal artery, all of which were connected to the Cormed infusor system, nine had operative placement of the Infusaid implantable pump with catheter placement into the hepatic artery via the gastroduodenal artery. The median survival for the entire group was 241 days. In those patients whose liver function tests (bilirubin and alkaline phosphatase) were less than two times normal, the median survival was 770 days. The median survival of the patients with greater than two times normal LFT's was 178 days. Two patients died of complications of the treatment. One who developed irreversible radiation hepatitis but at autopsy had only two areas of microscopic tumor foci in the liver and another who had received only 15 days of infusion and 1000 rad to liver. This patient developed irreversible chemical enteritis secondary to chemotherapy infusion into the superior mesenteric artery. Three patients have undergone abdominal reexploration and one at autopsy, who were found to have no gross evidence of tumor in the liver despite previous pathologic confirmation. It appears that some patients with minimal tumor burdens can have sterilization of their tumors. There were three cases of reversible liver function abnormalities. Complications associated with conventional intra-arterial chemotherapy (artery thrombosis, catheter sepsis and dislodgement, pump infusion variation and pump failure) were not seen with the Infusaid delivery system. The pump is refilled every 2-3 weeks via percutaneous puncture. All therapy was given on an outpatient basis. Pump acceptance and tolerance was 100%. Intra-arterial chemotherapy can now be accomplished without the morbidity associated with it in the past. The combination of chemotherapy and liver irradiation may offer improved survival in selected patients.

Campylobacter jejuni/coli strains were isolated from the faeces of 240 patients suffering from acute enteritis. The following characteristics were investigated: (i) growth at different temperatures, and on different substrates under either microaerophilic conditions or anaerobically, with fumarate or nitrate as terminal electron acceptors; (ii) production of H2S in cysteine-containing broth; (iii) hydrolysis of hippuric acid; (iv) DNase; (v) alkaline phosphatase; (vi) beta-lactamase; (vii) presence of menaquinone; and (viii) reduction of selenite. Based on characteristics (ii)-(v), the strains could be divided in 9 phenotypical groups. Most of the strains represented group 2 (DNase+, H2S+, hippurate hydrolysis+, alk. phosphatase-) (32%), and groups 8 (DNase-, H2S+, hippurate hydrolysis+, alk. phosphatase-) (32%). The other groups were of minor importance. On the other hand, most of the isolates from the United States (Weaver, 1981) fitted well into group 1 (DNase+, H2S+, hippurate hydrolysis+, alk. phosphatase+) which might demonstrate geographical variations among C. jejuni/coli.

The paper is concerned with the results of morphological and biochemical studies of the duodenum and ileum in young rabbits with salmonellosis. It was shown that all the parts of the small intestine were involved into the pathological process. Enzymopathy developed in the presence of acute catarrhal inflammation and erosive enteritis accompanied by ulceration of necrotized lymph follicles of Peyer's patches of the small intestine. The activity of maltase and alkaline phosphatase was found to be most vulnerable. Of crucial significance in the development of diarrhea in experimental young rabbits were pronounced morphological alterations and derangement of enzyme-forming function in the small intestine.

Rickets was investigated in 860 children in the 3 to 36 month age group in 21 villages attached to Sinik Health Centre, in northeastern Turkey. The blood calcium, phosphorus and alkaline phosphatase levels of suspect cases were determined following examination and wrist x-rays taken. The prevalence of cross-sectional rickets was determined, in the cohort group formed by removing the rickets cases (to the first group, advice was not given; to the second, 400 IU of vitamin D) and its incidence determined. The prevalence of rickets was calculated as 9.8% with no distinction observed between males and females (P > 0.05). It is higher in children in the 3-6 month group (23.97%) (P < 0.05); exposed rarely to the sun (P < 0.001); without fish in diet (P < 0.01); born to mother under 18 years old (P < 0.001); with a mother not using contraception (P < 0.01). The prevalence of acute respiratory infections (ARI) was calculated as 47.62% and 35.70% (P < 0.05) in children with and without rickets, respectively. The prevalence of enteritis was calculated as 29.76% and 18.43% (P < 0.05) in children with rickets and without rickets, respectively. Rickets was not seen where 400 IU of vitamin D was administered, while incidence for the twelve-month period was calculated as 3.8% in the other group. Combatting rickets is important in developing countries where deaths under five years are largely due to ARI and enteritis.
