The results of the determination of 24 basic blood chemistry variables from 262 men and 239 women, half of each group 44.4 +/- 0.9 and 63.0 +/- 0.9 (men) and 44.4 +/- 0.9 and 62.8 +/- 0.8 years old (women), resp., are compared. In men, only 6 analytes show significant differences between the age groups: Alanine aminotransferase decreases, aspartate aminotransferase decreases, iron decreases with p < 0.05; sodium increases, calcium decreases, protein (serum) decreases with p < 0.001. In women, 16 analytes, compared between both groups, are significantly different: Urea, uric acid, creatinine, triglycerides, total cholesterol, LDL cholesterol, LDL-C/HDL-C ratio, alanine aminotransferase, alkaline phosphatase, gamma-glutamyltransferase, sodium and ferritin are increased in the older group, whereas HDL cholesterol, iron, transferrin, and total protein are decreased. The sex differences are more distinct in the group of 44 years old persons than in the 63 years old one. These results will be completed by the comparison with the evaluation of the stored laboratory values of 9923 patients between 20 and 89 years old.

Cholecystectomized patients with recurrent attacks of right epigastric pain and with dilated common bile duct are a clinical challenge. In a number of these patients dilatation of the common bile duct is explained as a normal postoperative state following cholecystectomy and the recurrent pain attacks are of origin other than bile disorder, but in some cases dilatation of the common bile duct and attacks are caused by bile duct stones. The aim of the present work was to study the value of common plasma liver function tests in predicting bile duct stones in the group of non-icteric cholecystectomized patients with recurrent attacks of right epigastric pain and with dilated common bile duct. The study population comprised 24 consecutive non-icteric cholecystectomized patients admitted for elective endoscopic retrograde cholangiopancreatography because of attacks of right epigastric pain and dilated common bile duct in ultrasonography. All the liver function tests seemed to assist in separating patients with bile duct stones (n=11) from those without (n=13). Alanine aminotransferase levels were significantly higher (p=0.05) in patients with bile duct stones than in those without, but also alkaline phosphatase (p=0.07), gamma-glutamyl transferase (p=0.09) and bilirubin (p=0.09) levels seemed to be higher in patients with bile duct stones than in those without, although the differences in these values did not reach statistical significance. In conclusion, common plasma liver function tests assist in separating patients with bile duct stones from those without in this small but clinically important group of non-icteric cholecystectomized patients with recurrent attacks of right epigastric pain and with dilated common bile duct. However, the actual value of these measurements is limited in clinical decision making since overlapping of values occured.

Methidathion (MD) [ O, O-dimethyl S-(2,3-dihydro-5-methoxy-2-oxo-1,3,4-thiadiazol-3-ylmethyl) phosphorodithioate] is one of the most widely used organophosphate insecticides (OPIs) in agriculture and public health programmes. We have, therefore, examined the in vivo and in vitro effects of MD on the serum activities of cholinesterase (ChE), enzymes concerning liver damage and lipid peroxidation (LPO; only in vivo), and have evaluated the ameliorating effects of a combination of vitamins E and C against MD toxicity. The in vivo experimental groups were: control group, MD-treated group (MD), and a group treated with MD plus vitamin E plus vitamin C (MD+Vit). The MD and MD+Vit groups were treated orally with a single dose of 8 mg MD/kg body weight at 0 h. Vitamin E and vitamin C were injected at doses of 150 mg/kg body weight i.m. and 200 mg/kg body weight i.p., respectively, 30 min after the treatment with MD in the MD+Vit group. Blood samples were taken 24 h after the MD administration. For in vitro study, venous blood samples were obtained from volunteers, and serum recovered. The activities of serum enzymes were determined in each sample and these served as 0 h values. Each sample was divided into four portions, each of which served as one of the experimental groups, as follows: control group, vitamin E plus vitamin C group (Vit), MD-treated group (MD) and MD plus vitamin E plus vitamin C group (MD+Vit). Vitamin E and vitamin C were added at doses of 7.5 and 10 micro g/ml, respectively, into the Vit and MD+Vit groups. MD was added at doses of 0.4 mg/ml into the MD and MD+Vit groups. The activities of serum enzymes were determined in each sample at 24 h. The results of the in vivo experiment demonstrated that thiobarbituric acid reactive substances were increased in the MD group compared with the control group, and decreased in the MD+Vit group compared with MD group. ChE activity was decreased in both MD and MD+Vit groups compared with controls and increased in the MD+Vit group compared with the MD group. The activities of aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyltransferase (GGT) and lactate dehydrogenase (LDH) were increased in both the MD and MD+Vit groups compared with the control group. AST activity was decreased in MD+Vit group compared with the MD group. Alanine aminotransferase (ALT) activity was decreased in both the MD and MD+Vit groups compared with control group. The results of in vitro experiment showed that all enzyme activities remained unchanged in both the control and Vit groups compared with values at 0 h. The activities of ChE, ALT and LDH were decreased in both the MD and MD+Vit groups compared with 0 h values. There was no significant difference between the MD and MD+Vit groups. The activities of AST, ALP and GGT remained unchanged in all groups. From these results, it can be concluded that MD caused liver damage, and LPO may be one of the molecular mechanisms involved in MD-induced toxicity. Single-dose treatment with a combination of vitamins E and C after the administration of MD can reduce LPO caused by MD.

A prospective descriptive study of Primary Biliary Cirrhosis at Hospital Kuala Lumpur was undertaken from January 1992 to December 1999. A total of 17 patients were seen with a female to male ratio of 3.25:1. The mean age at presentation was 45.9 years (range: 14 years to 67 years) with a mean follow-up of 33.4 months (range: 3 months to 95 months). Fatigue was the most common clinical symptom at presentation. Alanine transaminase and alkaline phosphatase levels were elevated in 93% of patients at presentation. The antimitochondrial antibody was positive in 87% of patients. Ursodeoxycholic acid therapy resulted in significant symptomatic relief and biochemical improvement in all those who were treated.

In the Nordic Reference Interval Project (NORIP), data from 102 Nordic clinical chemical laboratories were obtained. Each laboratory reported analytical data on up to 25 of the most commonly used clinical biochemical properties, including results from each of a minimum of 25 reference individuals. A reference material consisting of a liquid frozen pool of serum with values traceable to reference methods (used as the project "calibrator" for non-enzymes to correct reference values) was measured together with other serum pool controls in each laboratory in the same analytical series as the project samples. The data on the controls were used to evaluate the analytical quality of the routine methods. For reference interval calculations, only such reference values on enzymes were accepted that were obtained by applying the International Federation of Clinical Chemistry (IFCC) compatible methods (37 degrees C), while "calibrator"-corrected reference values were used in the cases of non-enzymes. For each property, gender- and age-specific reference intervals were estimated, based on simple non-parametric calculations and using objective criteria to perform partitioning into subgroups. It is concluded that the same reference intervals are applicable in all five Nordic countries. The following descriptive data for the considered properties are presented in the tables: number of measurement values from each country and measurement system, certified/indicative target values for controls, differences between methods and measurement systems together with coefficients of variation, effects of control correction on the measurement values, differences between subgroups as determined by age, gender, country and material, and comparison of the new reference intervals with those presented in standard textbooks. The 25 components involved in this project were (listed in alphabetical order): Alanine transaminase, albumin, alkaline phosphatase, amylase, amylase pancreatic type, aspartate transaminase, bilirubin, calcium, carbamide, cholesterol, creatine kinase, creatininium, gamma-glutamyltransferase, glucose, HDL-cholesterol, iron, iron-binding capacity, lactate dehydrogenase, magnesium, phosphate, potassium, protein, sodium, triglyceride and urate.

The effects of co-administration of nicotinic acid (NA) and alcohol (Alc) on liver function in male Wistar rats were evaluated. The rats were randomized into five groups: (i) Olive oil (Oil), (ii) Alc+Oil, (iii) NA+Oil, (iv) NA+Alc+Oil, and (v) Controls (fed only normal rat chow). Alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (AP), total cholesterol and triglycerides (TG) were measured. Liver histopathology was also assessed. The Alc+Oil group had higher TG levels compared with the NA+Alc+Oil group and all other groups, as well. NA+Oil group had higher levels of AP compared with Alc+Oil and Oil groups. The NA+Oil group had higher ALT levels compared with the Oil group. The Oil group had lower ALT levels compared with the control group. The Alc+Oil group had higher AST levels compared with the NA+Alc+Oil group, as well as with all other groups. Liver histopathology was within the normal range. A moderate amount of Alc daily together with NA is safe in rats. The NA and Alc co-administration reduces the TG and AST levels in rats, compared with the administration of Alc alone.

Blood serum clinical biochemical parameters of fasted BUT Big 8 male turkeys were determined at the ages of 3 days, 4, 8, 12, 16 and 20 weeks, for a follow-up of the developmental changes of some serum metabolites, enzymes and ions. The serum protein content (total protein, albumin, globulin) increased with age, indicating also the moulting-associated metabolic changes in the age interval from the 8th to the 12th weeks. Creatinine was shown to have a peak at 3 days of age (role of muscle activity in thermogenesis), while urate concentration sensitively reflected the dietary protein amount. Serum triglycerides peaked at the time of yolk catabolism, while cholesterol was shown to indicate the moulting, as was serum malondialdehyde. Serum sodium content increased throughout the study. Alanine aminotransferase and aspartate aminotransferase activities increased along the ontogeny, while alkaline phosphatase activity decreased in parallel with the growth. Serum creatine kinase activity showed an over one-magnitude increase. General metabolic and enzymatic alterations were characteristic and applicable for the description of the ontogenetic development of a precocial (post-hatch triglyceride peak), large bodied, meat-type (lactate dehydrogenase, continuously increasing creatine kinase) bird species.

The liver is one of the organs involved in the multiorgan failure that occurs in sickle cell disease, the pathophysiology of liver disease in this condition is complex because of the interrelated multifactorial causes. Liver dysfunction was assessed in both paediatric and adult sickle cell disease patients in the steady state. The transaminases and alkaline phosphatase were analysed by automation while coagulation studies were done manually. The mean (range) of Alanine transaminase (ALT), Aspartate transaminase (AST) and alkaline phosphatase (ALP) were 23.0 (2-77) IU, 48.5 (15-120) IU, 227.5 (37-1200) IU respectively. ALT and AST levels were less than 100 IU in over 95% of the patients. The gender or age of the patients did not significantly affect the level of these three enzymes. There was close association between the liver size and elevation of the liver enzymes except for alkaline phosphatase (ALT=.017, AST=.009, ALP=.056). Twenty-five percent of the patients had normal enzymes while 13% had derangement of the three enzymes, 19%, 50% and 74% had abnormal ALT, AST and ALP respectively. Only 22% and 5% had deranged PT and APTT respectively. In conclusion minimal elevation of the tramsaminases which is not gender or age dependent were observed in steady state sickle cell disease, higher levels of alkaline phosphatase may be due to associated vasoocclussive crises involving the bones rather than a pathology of the liver.

The euryhaline fish, Oreochromis mossambicus was exposed to sub-lethal concentration (1.15 mg l(-1)) of a organophosphorus insecticide, monocrotophos (MCP) for 30 days and allowed to recover for seven days. Alanine aminotransferase (ALAT), aspartate aminotransferase (AAT), acid phosphatase (AcP), alkaline phosphatase (ALP), glycogen, lactate dehydrogenase (LDH), Reduced glutathione (GSH), gluthathione-S-transferase (GST) and acetylcholinesterase (AChE), were assayed in plasma and different tissues at regular intervals of day -3, -7, -15, -30 and after recovery period of seven days. The ALAT and AAT activities were increased in plasma and kidney, where as liver and gill showed decrease. Increase in AcP and ALP activities were observed in plasma, gill and kidney, and reduction of 42% and 50% was observed in liver. Glycogen was depleted in plasma, liver and gill indicates of typical stress related response of the fish with pesticide. LDH activity was decreased in liver and muscle, indicating tissue damage and muscular harm, but a significant increase in LDH activity in gill and brain was observed. Depletion in GSH activity was observed in all the tissues, there by enhancing the lipid peroxidation resulting in cell damage. The induction in hepatic GST levels indicates the protection against the toxicity of xenobiotic-induced lipid peroxidation. There was a significant recovery in all the above biochemical parameters studied in plasma and different tissues, after seven days recovery period. These results revealed that MCP affects the intermediary metabolism of O. mossambicus and that the assayed enzymes can work as good biomarkers of organophosphorus contamination.

Serum chemistry analyses represents a fundamental tool for the diagnosis and understanding of diseases in marine mammals. Although several studies are being conducted within the field of clinical pathology, haematological and serum chemistry data for Antillean manatees are deficient. The purpose of this study was to determine serum chemistry values for captive Antillean manatees within the CMA/Ibama facility in Brazil. Serum samples were obtained from five captive adult Antillean manatees fed with seagrass and analysed for aspartate aminotransferase, alanine aminotransferase, bilirubin, alkaline phosphatase, urea, creatinine, glucose, triglycerides, cholesterol, total protein, albumin, globulin, phosphate, chloride, calcium and uric acid. Blood chemistry parameters were determined using a semi-automatic analyzer. Maximum, minimum, mean and standard deviations were calculated for each serum chemistry parameter. Differences on the values of males and females were verified using an unpaired Student's t-test. All the parameters analysed were similar between sexes, with exception of AP, which was higher in females (191.43 +/- 31.86 U/l). Alanine aminotransferase and uric acid values for Trichechus manatus manatus are reported for the first time in this paper. This study is the first to report serum chemistry parameter values for long-term captive male and female Antillean manatees. Therefore, the lower values of albumin, phosphate, chloride, cholesterol and triglycerides obtained here highlight the importance of clinical pathology during health monitoring of captive marine mammals.
