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.

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.

In order to investigate the effects of exposure to possible environmental pollutants such as Cd, Pb and Hg on haematological and serum biochemistry values, New Zealand White female rabbits were treated orally with distilled water solutions of CdSO4 x H2O, Pb(NO3)2 and HgCl2 (n = 4/treatment) in concentrations of 2.3, 4.1, and 30 mg/kg dry matter, respectively, for 28 days. The initial concentrations of Cd, Pb, and Hg in serum were significantly increased by the treatment. Exposure to Pb significantly decreased the red blood cell (RBC) count, haemoglobin (Hgb) concentration and the haematocrit (Hct) value. The Zn-protoporphyrin concentration did not change as a result of Pb exposure. Pb and Hg loading significantly increased the aspartate aminotransferase (AST) activity. Alanine aminotransferase (ALT) activity was also increased by both Hg and Cd exposure. Comparing the treated and the control rabbits, all the trace elements studied significantly reduced the activity of enzymes in the pancreatic tissues. The haematological results indicate that hyperchromic macrocytic anaemia developed in rabbits treated with Pb. The increased activities of both AST and ALT indicate pathophysiological changes of the liver parenchyma, which was verified by focal fatty infiltration seen histopathologically. Cd exposure could exert a toxic effect on the kidneys, although the slight tubulonephrosis developed would not possibly affect the renal function. The reduced activities of amylase, trypsin, protease and lipase induced by Cd, Pb and Hg suggest toxicity to the pancreas.

We report on a 68-year-old female patient who was admitted with abdominal pain. Elevated lipase and CRP caused us to suspect pancreatitis. Because an enlarged pancreas head was found on ultrasound, an endoscopic retrograde cholangio- and pancreaticography was performed with a pethidine-containing premedication. Thereafter, bilirubin, gamma-glutamyl transpeptidase and alkaline phosphatase increased dramatically. There was also a moderate elevation of aspartate aminotransferase and alanine aminotransferase. A second endoscopic retrograde cholangio- and pancreaticography with the same premedication was performed in order to exclude an undetected concretion. This led to a further increase of bilirubin. An association with the drugs given as premedication was therefore suspected, and in fact, a hypersensitivity reaction towards pethidine was confirmed by the lymphocyte transformation test. We thus conclude that pethidine caused an immunologically mediated hepatic injury.

Phospholipid vesicles encapsulating Hb (Hb-vesicles: HbV) have been developed for use as artificial O(2) carriers (250 nm phi). As one of the safety evaluations, we analyzed the influence of HbV on the organ functions by laboratory tests of plasma on a total of 29 analytes. The HbV suspension ([Hb]=10 g/dl) was intravenously infused into male Wistar rats (20 ml/kg; whole blood = 56 ml/kg). The blood was withdrawn at 8h, and 1, 2, 3, and 7 days after infusion, and the plasma was ultracentrifuged to remove HbV in order to avoid its interference effect on the analytes. Enzyme concentrations, AST, ALT, ALP, and LAP showed significant, but minor changes, and did not show a sign of a deteriorative damage to the liver that was one of the main organs for the HbV entrapment and the succeeding metabolism. The amylase and lipase activities showed reversible changes, however, there was no morphological changes in pancreas. Plasma bilirubin and iron did not increase in spite of the fact that a large amount of Hb was metabolized in the macrophages. Cholesterols, phospholipids, and beta-lipoprotein transiently increased showing the maximum at 1 or 2 days, and returned to the control level at 7 days. They should be derived from the membrane components of HbV that are liberated from macrophages entrapping HbV. Together with the previous report of the prompt metabolism of HbV in the reticuloendothelial system by histopathological examination, it can be concluded that HbV infusion transiently modified the values of the analytes without any irreversible damage to the corresponding organs at the bolus infusion rate of 20 ml/kg.

Serum biochemical, hemostatic, and hematologic analytes were determined by four laboratories on dog serum or plasmas containing increasing amounts of hemolysate. From the results of testing, interferographs were prepared to aid in decision making and to enhance visualization of the effects of hemolysis on the determination of the analytes. Heniktsus consistently interfered with the analysis of creatinine phosphokinase, lactic dehydrogenase, aspartate aminotransferase, lipase, and albumin, all of which appeared to increase with increasing hemolysis. The results for the remainder of the biochemical, hemostatic, and hematologic analytes varied greatly among analyzers or methods, rarely in a predictable manner, indicating that each laboratory should evaluate the effects of hemolysis on each analyzer and for each method used, in order to make informed decisions on the use of hemolyzed but irreplaceable samples.
