A women, 50 years old, has been observed for 4 years because of recurrent infiltrations in both lungs. Biopsy of those lesions revealed sarcoid-like granulomas. Tubercle baccilli were not present in those lesions nor in the sputum or bronchial washings. Anti-tuberculosis therapy was without effect. On admission to our hospital she was in good performance state. There was an infiltration in the base of the left lung. Hepatosplenomegaly was observed on USG examination. Aspartate aminotransferase was 49 UI/l, alanine aminotransferase 70 UI/l. Alkaline phosphatase was 167 UI/l and the titer of antimitochondrial antibodies was 1:2000. Primary biliary cirrhosis was suspected, but the patient refused liver biopsy. Prednisone in the dose of 60 mg per day was given to suppress the granuloma formation in the lungs. During this treatment there was a decrease in size of liver and spleen, lung lesion disappeared and the titer of antimitochondrial antibodies decreased to 1:40. After 3 months of treatment the dose of prednisone was reduced gradually. When she was receiving 15 mg of prednisone every other day the titer of antimitochondrial antibodies rose to 1:8000 and the activity of alkaline phosphatase to 448 UI/l. At this time she accepted liver biopsy. Primary biliary cirrhosis was diagnosed. The possible connection between sarcoid-like granulomas in the lungs and the primary biliary cirrhosis is discussed.

Alcohol (ethanol) was administered chronically to female Sprague-Dawley rats in a nutritionally adequate, totally liquid diet for 28 days. This resulted in significant hepatic steatosis and lipid peroxidation. When taurine was administered for 2 days following alcohol withdrawal it was found to reduce alcohol-induced lipid peroxidation and completely reversed hepatic steatosis. The reversal of hepatic steatosis was demonstrated both biochemically and histologically. Two days following alcohol withdrawal, the apparent activity of the alcohol-inducible form of cytochrome P450 (CYP2E1) was unchanged although total cytochrome P450 content was increased. In addition, alcohol significantly inhibited hepatic methionine synthase activity and increased homocysteine excretion in urine. Although alcohol did not affect the urinary excretion of taurine (a non-invasive marker of liver damage), levels of serum and hepatic taurine were markedly raised in animals given taurine following their treatment with alcohol, compared to animals given taurine alone. There was evidence of slight bile duct injury in animals treated with alcohol and with alcohol followed by taurine, as indicated by raised serum alkaline phosphatase (ALP) and cholesterol. Aspartate aminotransferase (AST) was also slightly raised. The effects of taurine on reversing hepatic steatosis may be due to the enhanced secretion of hepatic triglycerides. It is suggested that increased bile flow as a result of taurine treatment may have contributed to the removal of lipid peroxides. These in-vivo findings demonstrate for the first time that hepatic steatosis and lipid peroxidation, occurring as a result of chronic alcohol consumption, can be reversed by administration of taurine to rats for 2 days.

Biochemical and hematimetric indicators of inflammation and cell damage were correlated with bilirubin and hepatic and pancreatic enzymes in 30 chronic male alcoholics admitted into psychiatric hospital for detoxification and treatment of alcoholism. Aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltransferase, alkaline phosphatase, and total bilirubin were altered, respectively, in 90%, 63%, 87%, 23% and 23% of the cases. None of the indicators of inflammation (lactic dehydrogenase, altered in 16% of the cases; alpha-1 globulin, 24%; alpha-2 globulin, 88%; leucocyte counts, 28%) was correlated with alterations of bilirubin or liver enzymes. Lactic dehydrogenase was poorly sensitive for detection of hepatocytic or muscular damage. Alterations of alpha-globulins seemed to have been due more to alcohol metabolism-induced increase of lipoproteins than to inflammation. Among indicators of cell damage, serum iron, increased in 40% of the cases, seemed to be related to liver damage while creatine phosphokinase, increased in 84% of the cases, related to muscle damage. Hyperamylasemia was found in 20% of the cases and significantly correlated with levels of bilirubin, alkaline phosphatase and gamma-glutamyltransferase. It was indicated that injuries of liver, pancreas, salivary glands, and muscle occurred in asymptomatic or oligosymptomatic chronic alcoholics.

Investigations in Prince William Sound (Alaska, USA) following the Exxon Valdez oil spill (EVOS) revealed that river otters (Lontra canadensis) on oiled shores had lower body mass and elevated values of biomarkers, than did otters living on nonoiled shores. In addition, otters from oiled areas selected different habitats, had larger home ranges, and less diverse diets than animals living in nonoiled areas. These differences between river otters from oiled shores and those from nonoiled areas strongly suggested that oil contamination had an effect on physiological and behavioral responses of otters. In this study, we explored the effects of crude oil contamination on river otters experimentally. We hypothesized that exposure to oil would result in elevated values of biomarkers, indicating induced physiological stress. Fifteen wild-caught male river otters were exposed to two levels of weathered crude oil (i.e., control, 5 ppm/day/kg body mass, and 50 ppm/day/kg body mass) under controlled conditions in captivity at the Alaska Sealife Center in Seward (Alaska, USA). Responses of captive river otters to oil ingestion provided mixed results in relation to our hypotheses. Although hemoglobin (Hb, and associated red blood cells) and white blood cells, and possibly interleukin-6 immunoreactive responded in the expected manner, other parameters did not. Aspartate aminotransferase, alanine aminotransferase, and haptoglobin (Hp), did not increase in response to oiling or decreased during rehabilitation. Conversely, principle-component analysis identified values of alkaline phosphatase as responding to oil ingestion in river otters. Our results suggested that opposing processes were concurring in the oiled otters. Elevated production of Hp in response to tissue damage by hydrocarbons likely occurred at the same time with increased removal of Hp-Hb complex from the serum, producing an undetermined pattern in the secretion of Hp. Thus, the use of individual biomarkers as indicators of exposure to pollutants may lead to erroneous conclusions because interactions in vivo can be complicated and act in opposite directions. Additionally, the biomarkers used in investigating effects of oiling on live animals usually are related to the heme molecule. Because of the opposing processes that may occur within an animal, data from a suite of heme-related biomarkers may produce results that are difficult to interpret. Therefore, we advocate the exploration and development of other biomarkers that will be independent from the heme cycle and provide additional information to the effect of oiling on live mammals.

The present study was carried out to investigate the effects of Lupinus albus, L. (Lupinus termis), family L. leguminosae, Cymbopogon proximus, (Halfa barr), family Gramineae, and Zygophyllum coccineum L. (Kammun quaramany), family L. Zygophyllacae on biochemical parameters in alloxan-induced diabetic rats. A dose of 1.5 ml of aqueous suspension of each herb/100 g body weight (equivalent to 75 mg/100 g b.wt.) was orally administered daily to alloxan-diabetic rats for 4 weeks. The levels of glucose, urea, creatinine and bilirubin were significantly (P<0.05) increased in plasma of alloxan-diabetic rats compared with the control group. In contrast, total protein and albumin were significantly decreased by 25 and 46%, respectively, versus control. Treatment of the diabetic rats with repeated doses of any one of the three herb suspensions could restore the changes of the above parameters to their normal levels after 4 weeks of treatment. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH) and alkaline phosphatase (AlP) activities were significantly (P<0.05) increased in the plasma of alloxan-diabetic rats. However, acetylcholinesterase activity was significantly (P<0.05) decreased in the plasma compared with the control group, whereas, such activity did not change in brain. The activities of AST, ALT and LDH were significantly (P<0.05) decreased in the liver of alloxan-diabetic rats by 58, 21 and 40%, respectively, and such activities increased in testes by 39, 26 and 26%, respectively, compared with the control group. Also, brain LDH was significantly (P<0.05) increased. Treatment of the diabetic rats with the aqueous suspension of the tested herbs restored the activities of the above enzymes to their normal level in plasma, liver and testes. The present results showed that the herb suspensions exerted antihyperglycemic effects and consequently may alleviate liver and renal damage caused by alloxan-induced diabetes.

Testosterone secretion in response to GnRH stimulation and enzymatic activity of semen plasma was evaluated comparatively in rams with or without genital abnormality. Scrota, testes and epididymides of 128 rams between 1.5 and 6 years old from various breeds were examined clinically and ultrasonographically. Bilaterally cryptorchid rams (n = 2), and rams with focal testicular degeneration (n = 3) or unilateral sperm granuloma localized in the caput (n = 3) epididymis or the cauda epididymis (n = 3), diagnosed by either clinical or ultrasonographic examination, were selected for the further investigation of spermatologic parameters, testosterone secretion in response to GnRH stimulation, and enzymatic activity of semen plasma before histopathologic confirmation of lesions. Except for the cryptorchid rams, sperm parameters determined in ejaculates were similar to intact controls (n = 3). GnRH administration increased plasma testosterone levels significantly irrespective of the type of genital pathology (P < 0.01). The testosterone response calculated based on area under the curve following GnRH administration in rams having genital abnormality was not significantly different from the controls. Aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) activity in the semen plasma varied between rams, with the lowest mean values in the bilaterally cryptorchid group (P < 0.05). Spermatic granuloma localized either in the caput or cauda of the epididymis was associated with a significant reduction in the semen plasma AST activity compared to controls (P < 0.01). In conclusion, our results indicated that the ability of testicular tissue to secrete testosterone in response to GnRH stimulation in rams with bilateral cryptorchidism, focal testicular degeneration and unilateral sperm granuloma was similar to that of intact controls, and that reduced semen plasma AST activity may have a diagnostic value in the diagnosis of the epididymal obstruction in rams. Focal testicular degeneration did not influence AST, alkaline phosphatase (ALP) and LDH activity in semen plasma.

The effects of ionophore supplementation on selected serum constituents of sheep consuming locoweed were investigated. Sixteen sheep were allotted by weight to a 2x2 factorial arrangement of treatments: 1) no locoweed, no lasalocid, 2) no locoweed, 0.75 mg lasalocid/kg BW, 3) 0.5 mg swainsonine/kg BW, no lasalocid, 4) 0.5 mg swainsonine/kg BW, 0.75 mg lasalocid/kg BW. Swainsonine was provided by locoweed (Oxytropissericea), and sheep were fed a blue grama based diet at 2.5% BW for a 35 d treatment period. Diets were formulated to be isocaloric and isonitrogenous. Blood samples were collected on d 1, 7,14, 21, 31 and 35 to determine serum swainsonine concentration, alkaline phosphatase, total iron, aspartate aminotransferase, g-glutamyltransferase, and lactate dehydrogenase activity and total cholesterol, and triglyceride concentrations. No lasalocid by locoweed interaction (P > 0.4) was noted for any response variable measured. Average daily gains (P = 0.4) and orts (P = 0.7) were not affected by the treatments. No lasalocid treatment (P = 0.7) or day (P = 0.1) effect of serum swainsonine was observed. A locoweed by day interaction (P < 0.0001) of serum alkaline phosphatase was detected. Alkaline phosphatase levels were elevated (P < 0.01) for locoweed treated sheep at 24 h following initial exposure and remained elevated throughout the trail. Total iron was suppressed (P < 0.08) in locoweed fed sheep. A day effect (P < 0.02) was observed for serum iron. However, no linear, quadratic, or cubic effects of day were noted (P >0.2). A locoweed by day interaction (P < 0.0001) of serum aspartate aminotransferase and g-glutamyltransferase was detected. Aspartate aminotransferase levels were elevated (P < 0.0001) by d 7 for locoweed treated animals and remained elevated throughout the trial. g--Glutamyltransferase levels were suppressed (P < 0.0001) by day 7 for locoweed treated animals and remained suppressed throughout the trial. A locoweed by day interaction (P = 0.06) of serum cholesterol was detected. However, no linear, quadratic, or cubic effects of day were detected (P = 0.2). Lasalocid treatment had no effect on any serum constituent measured. Use of lasalocid in grazing animals should not increase the likelihood of locoweed intoxication.

OBJECTIVE: The objective of this study was to analyze the incidence and significance of hepatic dysfunction after cardiac surgery in children. DESIGN: Prospective, observational study. SETTING: Pediatric intensive care unit of a university hospital. PATIENTS: The study consisted of 232 children ranging in age from newborn to 17 years with no history of liver disease. MEASUREMENTS AND MAIN RESULTS: Aspartate aminotransferase (AST), alanine aminotransferase (ALT), gammaglutamyltranspeptidase (GGT), alkaline phosphatase, total and conjugated bilirubin, blood glucose, urea, creatinine, and coagulation studies were determined at admission, at 24 and 48 hrs, and at 7 days. Hepatic dysfunction was taken as an ALT of > 100 IU/L or a moderate or high hepatic score. The statistical study included bivariate analysis and multivariate logistic regression to study the risk factors for hepatic dysfunction. Twenty-one patients (9%) showed an ALT > 100 IU/L, and 29.3% had a moderate or high hepatic score. A relationship was found between hepatic dysfunction and the type of cardiopathy (D-transposition of the great arteries and coarctation of the aorta), shock, the administration of dopamine or epinephrine, renal insufficiency, the presence of pulmonary changes (pulmonary edema, atelectasis, pulmonary hypertension, hypoxemia), hematologic disturbances (prothrombin time, kaolin-cephalin time, fibrinogen, and platelets), and the need for a greater number of transfusions of packed cells, plasma, and platelets. Compared with 7.6% of the rest of the patients (p <.001), 38% of patients with an ALT > 100 IU/L died. The hepatic score of those patients who died was 4.2 (2.3)-higher than that of the survivors at 1.5 (1.8), (p <.001). Shock and renal insufficiency were the factors most significantly related to the development of hepatic dysfunction. CONCLUSIONS: Hepatic dysfunction is an uncommon complication in children after cardiac surgery. This complication is related mainly to hemodynamic disturbances and renal insufficiency and is an indicator of poor prognosis.

For a long time, aluminium (Al) has been considered an indifferent element from a toxicological point of view. In recent years, however, Al has been implicated in the pathogenesis of several clinical disorders, such as dialysis dementia, the fulminant neurological disorder that can develop in patients on renal dialysis. Therefore, the present experiment was carried out to determine the effectiveness of l-ascorbic acid (AA) in alleviating the toxicity of aluminium chloride (AlCl3) on certain hemato-biochemical parameters, lipid peroxidation and enzyme activities of male New Zealand white rabbits. Six rabbits per group were assigned to 1 of 4 treatment groups: 0mg AA and 0mg AlCl3/kg body weight (BW) (control); 40 mg AA/kg BW; 34 mg AlCl3/kg BW (1/25 LD50); 34 mg AlCl3 plus 40 mg AA/kg BW. Rabbits were orally administered their respective doses every other day for 16 weeks. Evaluations were made for lipid peroxidation, enzyme activities and hemato-biochemical parameters. Results obtained showed that AlCl3 significantly (P<0.05) induced free radicals and decreased the activity of glutathione S-transferase (GST) and the levels of sulfhydryl groups (SH groups) in rabbit plasma, liver, brain, testes and kidney. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (AlP), acid phosphatase (AcP), and phosphorylase activities were significantly decreased in liver and testes due to AlCl3 administration. While, plasma, liver, testes and brain lactate dehydrogenase (LDH) activities were significantly increased. Contrariwise, the activity of acetylcholinesterase (AChE) was significantly decreased in brain and plasma. Aluminium treatment caused a significant decrease in plasma total lipids (TL), blood haemoglobin (Hb), total erythrocytic count (TEC) and packed cell volume (PCV), and increased total leukocyte count (TLC) and the concentrations of glucose, urea, creatinine, bilirubin and cholesterol. Ascorbic acid alone significantly decreased the levels of free radicals, TL, cholesterol, glucose and creatinine, and increased the activity of GST, SH groups, Hb, TEC and PCV. While, the rest of the tested parameters were not affected. Also, the present study showed that ascorbic acid can be effective in the protection of aluminium-induced toxicity.

Substantial fluid shifts occur during liposuction as wetting solution is infiltrated subcutaneously and fat is evacuated, causing potential electrolyte imbalances. In the porcine model for large-volume liposuction, plasma aspartate aminotransferase and alanine transaminase levels were elevated following liposuction. These results raised concerns for possible mechanical injury and/or lidocaine-induced hepatocellular toxicity in a clinical setting. The first objective of this human model study was to explore the effect of the liposuction procedure on electrolyte balance. The second objective was to determine whether elevated plasma aminotransferase levels were observed subsequent to large-volume liposuction. Five female volunteers underwent three-stage, ultrasound-assisted liposuction. Blood samples were collected perioperatively. Plasma levels of sodium, potassium, venous carbon dioxide, blood urea nitrogen, chloride, and creatinine were determined. Liver function analyte levels were measured, including albumin, total protein, aspartate aminotransferase, and alanine transaminase, alkaline phosphatase, gamma-glutamyl transpeptidase, and total bilirubin. To further define intracellular enzyme release, creatine kinase levels were measured. Mild hyponatremia was evident postoperatively (134 to 136 mmol/liter) in four patients. Hypokalemia was evident intraoperatively in all subjects (mean +/- SEM; 3.3 +/- 0.16 mmol/liter; range, 3.0 to 3.4 mmol/liter). Hypoalbuminemia and hypoproteinemia were observed throughout the study (baseline: 2.9 +/- 0.2 g/dl; range, 2.6 to 3.5 g/dl), decreasing to 10 to 40 percent 24 hours postoperatively (2.0 +/- 0.2 g/dl; range, 1.7 to 2.1 g/dl). Aspartate aminotransferase, alanine transaminase, and creatine kinase levels were significantly elevated after the procedure (190 +/- 47.1 U/liter, 50 +/- 7.7 U/liter, and 11,219 +/- 2556.7 U/liter, respectively) (p < 0.01). Release of antidiuretic hormone and even mildly hypotonic intravenous fluid infiltration have long been known to cause hyponatremia postoperatively. Intraoperative hypokalemia is associated with hypocarbia and respiratory alkalosis and the elevated epinephrine levels observed in the concurrent study. Factors having the greatest initial impact on diminished serum albumin and protein levels postoperatively are redistribution and hemodilution. Subsequent diminished viscosity may significantly affect postoperative hemodynamics. Elevated aspartate aminotransferase, alanine transaminase, and creatine kinase levels are associated with skeletal muscle injury, adipocyte lysis, and/or hepatic damage. Therefore, tissue injury is associated with large-volume liposuction as observed in several cellularly released enzymes. Future clinical studies are required to determine the degree of injury and specific tissues that are damaged or sensitive to mechanical trauma and/or drugs used in large-volume liposuction.
