A squirrel monkey (Saimiri sciureus) presented with wasting, vomiting and diarrhoea. Haematology revealed elevation of creatinine phosphokinase, lactic dehydrogenase, alanine aminotransferase, amylase and lipase, together with azotaemia and hypoalbuminaemia. Prominent findings were chronic pancreatitis with acinar and ductal plugs, granulomatous and necrotizing peripancreatic steatitis, degenerative myopathy, testicular atrophy, candidiasis and bacterial necrotizing glossitis. Antioxidant analyses revealed low concentrations of serum vitamin E (and apparently A), hepatic selenium and hair zinc. Pancreatitis may have caused malabsorption and maldigestion, associated with deficiency of multiple antioxidants.

This randomized, single blind clinical trial was performed to compare the efficacy and toxicity of BP88 Sodium Stibogluconate (SS) to Glucantime(R) (N-methyl-glucamine), (GL). Sixty-three patients were randomly assigned to one of two groups: 32 patients were treated with GL and 3l patients were treated with SS. Both groups received 15mg Sb+5/kg/day for 20 days. Toxicity was evaluated through EKG, urea, creatinine, AST, ALT, alkaline phosphatase, amylase, and lipase, assessed before treatment, on day 10 and day 20 of treatment and 90 days after treatment. In the group treated with GL, 81% (26/32) of patients were cured compared to 77% (24/31) in the SS group. Five (16%) patients relapsed in the GL group compared to 6 (19%) in the SS group. One patient in each group did not respond to treatment. AST, ALT, amylase, and lipase were more elevated in the SS group (p < 0.05). In conclusion, the efficacy of both treatments was similar although there was more toxicity in the ES group.

The commutability of 13 control materials was evaluated by performing parallel measurements on two different analysers: a Synchron CX-5 Delta from Beckman-Coulter and a Vitros 950 from Ortho-Clinical Diagnostics. Twenty three clinical chemistry analytes (substrates, electrolytes and enzymatic activities) were determined in plasma from 15 different patients in order to define intermethod relationship for each analyte. The relationship observed for each control material was compared to those obtained for patients' specimens. The results show that commutability depends both on the tested analyte and on the control material. No totally commutable material has been found for the whole set of tested parameters. Most control materials were commutable for inorganic phosphate, glucose, chloride, triglycerides, alanine aminotransferase, amylase and y-glutamyltransfera-se, but less than a quarter of control materials were commutable for sodium, calcium, creatinine, alkaline phosphatase and lipase. Seven materials were commutable for more than half of the analytes, whereas five control materials were commutable for less than a quarter of these analytes. We propose to verify the commutability of materials before their use in an external quality control assessement.

The purpose of this study was to investigate whether an intra-abdominal pressure (IAP) of 30 mmHg lasting 24 h in a porcine model will lead to a condition comparable with the abdominal compartment syndrome (ACS) in humans. We examined 12 intubated and anesthetized domestic pigs with a mean body weight of 52.5 +/- 4.9 kg. Using a CO2 pneumoperitoneum, the IAP was increased to 30 mmHg (study group, n = 6) for an investigation period of 24 h. In the control group, the IAP remained unchanged. Investigated parameters were cardiac output (CO), peak inspiratory pressure (PIP), urine output (UO), as well as serum alanine aminotransferase (ALT), lactate, lipase, and alkaline phosphatase (AP). Additionally, histopathological examinations were performed. In the study group, CO was significantly reduced compared with the control group. All animals of this group became anuric and their PIP exceeded 40 cm H2O. Furthermore, ALT, AP, lipase, and lactate were significantly increased. Histopathologically, high-grade atelectasis in the lower lobes of the lung together with medium grade liver necrosis, medium grade proximal tubular epithelial necrosis, and medium grade mucosal bowel damage were observed. In this porcine model, an intra-abdominal pressure of 30 mmHg led to a condition comparable with the ACS. Because function or integrity of additional organ systems was impaired, an IAP of 30 mmHg has to be considered a predisposition for the multi-organ dysfunction syndrome in this porcine model.

Quantitative determination of newly reported enzymes activity in the crude skin toxin (CST) of catfish revealed highest activities of hyaluronidase and lipase, lesser activities of phospholipase A2, lactate dehydrogenase (LDH), cholinesterase (CE), alkaline phosphatase (ALP), and aspartate transaminase (AST), and least activities of proteinase and 5-nucleotidase (5'-NT). The CST has a hemolytic activity of 54% and no ichthyotoxicity up to 500 ug/ml. The chosen dose of CST (LD12.5) showed a potential cytotoxic activity against solid Ehrlich carcinoma-bearing mice demonstrated by an increase in the mean survival time (238.8%) and tumor growth inhibition ratio (T/C) of 73%. The CST ameliorated the relative weights of heart and liver after three weeks, while modulating the elevation in the relative spleen weight throughout the treatment periods (three, six, and nine weeks). The levels of serum triglyceride, total cholesterol, and liver total lipids were normalized after three weeks, whereas the serum albumin and hepatic glycogen concentrations, as well as ALT, AST, 5'-NT, and G-6-Pase activities were ameliorated after 6 weeks. Serum levels of glucose, LDH, and creatine kinase (CK) activities were significantly modulated throughout the treatment periods. Histological examinations of the tumor and liver tissues of treated tumor-bearing animals were carried out. Tumor tissues showed many cytolytic and cytopathic changes after treatment, while liver tissues showed moderate dysplastic changes after six weeks of treatment, which became more marked after nine weeks.

To assess changes in 24 blood constituents in frozen serum and heparinized plasma, blood samples were drawn from 10 clinically normal German Shepherd army dogs. The storage characteristics of nine enzymes (ALP, ALT, amylase, AST, CK, GGT, GLDH, LDH, lipase), and 15 metabolites and minerals (albumin, bile acids, bilirubin, calcium, cholesterol, creatinine, fructosamine, glucose, magnesium, phosphate, potassium, protein, sodium, triglycerides, urea) were studied. Parallel samples of serum and heparinized plasma were stored for 90 and 240 days at two different storage temperatures, -200 degrees C and -700 degrees C. Sixteen of the 24 analytes (ALP, ALT, amylase, AST, CK, GGT, GLDH, LDH, bile acids, calcium, cholesterol, creatinine, fructosamine, magnesium, phosphate, urea) showed statistically significant (p < 0.05) changes during the storage period related to storage time, storage temperature, and sample type. Seven of the analytes (amylase, GGT, GLDH, LDH, bile acids, fructosamine, magnesium) showed changes of possible clinical importance with mean differences from baseline larger than 20% for the enzymes and 10% for the metabolites and minerals during the storage periods.

The stability and storage characteristics of 24 blood constituents from dogs including nine enzymes (ALP, ALT, amylase, AST, CK, GGT, GLDH, LDH, lipase), 15 metabolites and minerals (albumin, bile acids, bilirubin, calcium, cholesterol, creatinine, fructosamine, glucose, magnesium, phosphate, potassium, protein, sodium, triglycerides, urea) were studied. Conditions studied included storing of nonanticoagulated and heparinized whole blood for 3 days (Part A), and storing of serum and heparinized plasma for 3 days (Part B). The storage temperature for both studies was +4 degrees C from day 0 to day 1, and +20 degrees C, from day 1 to day 2 and 3. Eight of 24 analytes showed no significant differences (p > 0.05) for three days in whole blood. However, the stability of all 24 analytes greatly improved by storing serum or heparinized plasma compared to nonanticoagulated or heparinized whole blood. In stored serum or heparinized plasma, 20 of 24 analytes showed no significant differences (p < 0.05) for 3 days. Nine of 24 analytes showed significant differences (p < 0.05) between serum and heparinized plasma, where CK, LDH, GGT, and potassium showed differences of possible clinical importance. This study strongly supports the practice of separating serum/plasma from clot/cells as promptly as possible to achieve improved stability for most analytes under test.

A 12-year-old girl underwent laparoscopy-assisted splenectomy and cholecystectomy with removal of her spleen through a small Pfannenstiel incision. She had an unremarkable postoperative course but returned 16 days later because of increasing right-sided abdominal pain. The pain was constant, sharp, and stabbing without radiation. Abdominal examination showed diffuse right upper quadrant and epigastric tenderness without peritoneal irritation. Laboratory test results included white blood cell count, 14.4 x 10(9)/mm3; hemoglobin, 8.5 g/dL; platelets, 1,483,000; and normal values for lipase, amylase, aspartate transaminase, and alanine transaminase. Evaluation with ultrasonography and vessel Doppler studies showed an occlusive thrombus throughout the portal and splenic veins. The patient underwent intravenous heparin anticoagulation therapy. Her symptoms resolved completely over the next 2 days. The patient is currently receiving warfarin and anagrelide as an outpatient (international normalized ratio, 2). There were no long-term complications caused by portal vein thrombosis. This is the first reported case of portal vein thrombosis after laparoscopic splenectomy in the pediatric population.

This study describes a free-hand technique for percutaneous pancreatic biopsy in cattle with ultrasound-guidance using a 14G spinal biopsy needle. Its safety was evaluated based on 36 consecutive procedures. To assess the immediate effects of pancreatic biopsy, 31 cows were necropsied shortly after the procedure and examined. The remaining five cows were examined daily for eight days and then necropsied and examined. No life-threatening complications nor clinically detectable abnormalities were observed. Changes indicative of inflammation were not apparent in total and differential WBC counts or in total protein and fibrinogen concentrations. A small increase of amylase activity was detected in only one cow kept for the eight-day observation period. Serum lipase activity increased significantly on day four after biopsy. Urea nitrogen, creatinine, glucose and the activities of aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyltransferase remained within reference ranges. Changes in the peritoneum and pancreas observed at necropsy were negligible. We conclude that percutaneous ultrasound-guided pancreatic biopsy did not appear to influence the cow's condition adversely and the procedure provided an excellent method of obtaining a pancreatic specimen for histological examination. The procedure was considered safe, fast, cost-effective, and practical when performed properly. We believe that the technique can be used in cows with suspected pancreatic disease for making an ante mortem diagnosis.

Extrahepatic manifestations of chronic hepatitis C virus (HCV) infection have been well described. However, hyperlipasemia and/or pancreatitis have not been reported. Following the observation that several HCV patients had elevated lipase levels, this retrospective study was conducted to assess the association between hyperlipasemia and/or pancreatitis with hepatitis C infection. Of 204 subjects who underwent evaluation for hepatitis C, 103 had lipase levels determined at baseline. The control group consisted of 41 nonHCV subjects with a variety of gastrointestinal diseases including 18 with nonalcoholic liver disease. Twenty-five percent of HCV patients had elevated lipase at baseline as compared to 10% of controls (P = 0.04; OR = 3.1; 95% CI: 1.02-9.60). Mean lipase levels were 253 +/- 72 units/liter (normal range 114-286 units/liter and 210 +/- 42 units/liter for the HCV and control groups, respectively (P = 0.002). No significant difference in amylase was found between the groups. There was a significant association between ALT (> 1.5 times the upper limit of normal) and lipase (P = 0.02; OR = 3.0; 95% CI: 1.1-7.5). Among 30 patients who received interferon-based therapy +/- ribavirin, 11 had elevated lipase at baseline. Six of these patients responded to therapy and demonstrated normalization of lipase levels. In contrast, all nonresponders with baseline hyperlipasemia continued to have high lipase levels (P = 0.17; OR = 4.0; 95% CI: 0.6-28.4). Furthermore, only 3 of 8 (37.5%) patients with normal lipase responded to treatment as compared to 6 of 10 (60%) of hyperlipasemic patients (P = 0.36; OR = 2.5; 95% CI: 0.4-16.9). In conclusion, hyperlipasemia and/or subclinical pancreatitis may represent extrahepatic manifestations of HCV infection and should not preclude treatment.
