The critical difference, which may help to judge whether the difference between two consecutive analytical results may be safely ascribed to natural variation or not, was calculated for 12 clinical chemical components determined in blood samples collected once a week for 5 consecutive weeks from 19 clinically healthy Red Danish dairy cows. For each clinical chemical component, the total variance of the analytical results was divided into the component of variance between cows (S2Inter), the component of variance for weeks within cows (S2Intra) and the component of variance for measurements (S2Anal) using nested analysis of variance. The critical difference calculated in absolute values from S2Intra and S2Anal was 0.15 mu kat per 1 for alanine aminotransferase, 0.55 mu kat per 1 for aspartate aminotransferase, 0.57 mu kat per 1 for alkaline phosphatase, 0.14 mu kat per 1 for gamma-glutamyltransferase, 1.95 mu kat per 1 for creatine kinase, 2.23 mmol per 1 for urea, 22 mu mol per 1 for creatinine, 2.4 g per 1 for albumin, 10.0 g per 1 for serum protein Total, 0.71 mmol per 1 for glucose, 0.54 mmol per 1 for calcium and 0.25 mmol per 1 for magnesium. These critical differences may be used as guidelines to evaluate the difference between two consecutive analytical results in cows. However, the analytical results should not be assessed by the critical differences alone, but should also be compared with the corresponding reference intervals.

Total serum protein, serum albumin, total urine protein excretion, and the serum activity of several enzymes--aldolase (ALS), cholinesterase (CHS), leucine aminopeptidase (LAP), isocitrate dehydrogenase (ICD), aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), alpha-hydroxybutyrate dehydrogenase (HBD), creatine kinase (CK), alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT)--were estimated in rats with nephrotic syndrome (NS) at 2, 4, 6, 8, 10, 12, 16, 20, and 30 days after a single injection of puromycin aminonucleoside (PAN). It was found that: (a) total serum protein and serum albumin diminished on day 4 and returned to control values on days 20 and 30, respectively; (b) total urine protein excretion rose on day 4, reached a peak value on day 8, and then fell substantially but still remained higher than control values on day 30; (c) ALS and CHS activities increased; (d) LAP, ICD, and AST activities showed a biphasic pattern, first increasing and then decreasing; (e) ALT, LDH, HBD, CK, and ALP activities decreased; and (f) GGT activity remained unchanged. The differences in the profiles of the enzyme activities suggest their independent regulation in experimental NS induced by PAN.

The present study examined the preventive effects of green tea extract on D-galactosamine (GalN)-induced hepatic injury in rats, an animal model of viral hepatitis. A single i.p.-injection of GalN (700 mg/kg) to male Wistar rats caused fulminant hepatitis by 48 hr as assessed by marked increases in the serum aspartate aminotransferase (GOT), alanine aminotransferase (GPT) and alkaline phosphatase (ALP) activities; decreases in the serum protein and cholesterol levels and the amount of liver microsome P-450; and marked changes in organ weights. The lecithin: cholesterol acyltransferase (LCAT) activity markedly increased at 8 hr and markedly decreased at 24 hr after the GalN injection. In the experiment, animals were orally administered green tea extract at doses of 50, 100 or 200 mg/kg five times each before and after the GalN injection. Treatment with green tea extract significantly prevented the increases in the GOT, GPT and ALP activities in a dose-related manner. It also significantly prevented the decreases in serum albumin and total cholesterol, although not in a dose-related manner. A tendency to prevent the increase in LCAT activity and the decrease in liver microsome P-450 was also noted. Little effect was found on the other abnormal changes in the serum lipids and proteins and the organ weights. These results suggest that green tea may have an ameliorating effect on hepatic dysfunction.

The purpose of the present study was to calculate the critical differences between two analytical results for 23 routinely used bovine clinical-chemical parameters. The critical difference can be used to judge whether the difference between two consecutive analytical results from the same animal is due to natural variation or not. From 20 cows, blood samples were collected once daily for five days, and the interindividual variance, the intra-individual variance, and the analytical variance were calculated using nested analysis of variance. The critical difference both in absolute values and in percentages was calculated from these variances. The main conclusions were that the critical difference in percentages was in general between 10 and 40 per cent but varied from 10.6 per cent for sodium to 280.2 per cent for lactate and that the analytical variation was generally in accordance with accepted standards, although the analytical variation for alkaline phosphatase, total serum protein, urea and fructosamine should be improved.

Caramel Colour IV, a type of caramel colour used in the manufacture of cola soft drinks, was evaluated for subchronic and chronic toxicity in rats, and carcinogenicity in Fischer-344 (F344) rats and B6C3F1 mice. In each of the studies, Caramel Colour IV was mixed with demineralized water and the solutions given to the animals ad lib. in the drinking fluid. The concentrations of Caramel Colour IV in the drinking fluid were adjusted periodically to achieve the desired caramel colour intake per kg body weight. In the range-finding studies, groups of 30 rats/sex were given Caramel Colour IV at levels of 0, 15, 20, 25 or 30 g/kg for 13 wk, and groups of 10 male rats were given levels of 0, 2.5, 5, 10 or 15 g/kg for 6 wk followed, for some dose groups, by a 2-wk withdrawal period, and then re-initiation of dosing for another 2 wk. In the rat chronic toxicity study, levels of Caramel Colour IV of 0, 2.5, 5, 7.5 or 10 g/kg were given to groups of 25 rats/sex for 12 months. The test groups in the rat and mouse carcinogenicity studies were composed of 50 animals/sex and each species was given the caramel colour at levels of 0, 0, 2.5, 5 or 10 g/kg for 24 months. In each of the studies, treated animals tended to have dose-related lower water consumption than controls. This was attributed to poor palatability of the drinking fluid, and was generally associated with decreased food consumption and body weights. Rats given caramel colour often had soft or liquid malodorous faeces although there were no treatment-related ante-mortem observations in mice. Blood biochemical changes in the rat (i.e. reduced blood urea nitrogen, alkaline phosphatase and total serum protein) appeared to be related to dietary influences and were not considered toxicologically significant. There were no treatment-related alterations in haematological variables or treatment-related differences in survival or in the incidence of benign or malignant tumours among treated and control groups and no toxicologically important pathological findings. On the basis of these studies, Caramel Colour IV was not toxic or carcinogenic in F344 rats or B6C3F1 mice. The highest dose level tested in the long-term studies (10 g/kg) was considered to be the no-observed-adverse-effect level (NOAEL).

The effects of ursodeoxycholic acid (UDCA, 450 mg daily) in patients with histologically proven chronic active hepatitis (CAH) have been evaluated in a randomized, double-blind, placebo-controlled study. Twenty-six patients with serum alanine aminotransferase (ALT) values at least twice the normal upper limit in two of three pre-treatment tests received UDCA or a placebo for twelve weeks. In all UDCA-treated patients, serum aspartate amino-transferase (AST), ALT, gamma-glutamyl transpeptidase (GGT) and alkaline phosphatase (AP) fell significantly after 4 weeks of treatment. There was a further decrease at the end of therapy, as well as a small but significant fall in total serum bilirubin. Conversely, 4 weeks after suspension of therapy, serum enzyme levels had increased, reaching values not much lower than those recorded before treatment. Total serum protein, albumin and gamma-globulin did not change after UDCA treatment. In the placebo group no significant variation in the test results were found. The results indicate that UDCA therapy in CAH, as has been observed in primary biliary cirrhosis and primary sclerosing cholangitis, is able to improve several indices of liver damage, without producing any toxic adverse effects.

Monoclonal gammopathies can either be benign or more commonly malignant. The commonest disease associated with it is multiple myeloma. Over the seven-year period 1984-1990, two hundred and thirty-four monoclonal gammopathies were seen at the University Hospital, Jamaica. Multiple myeloma was diagnosed in one hundred and fifty-six cases (84 males and 72 females). The diagnoses of most of the others were not known as the samples came from other institutions. Of the patients with myeloma, the most common immunoglobulin type was IgG followed by IgA and then pure light chain disease. Only in about half of the cases where urine was analysed was Bence-Jones protein found. The majority of the cases had abnormal total serum protein, albumin and total globulin concentrations. Most of the cases also were in renal failure. Hypercalcaemia, hyperphosphataemia, elevated alkaline phosphatase, gammaglutamyl transferase and aspartate aminotransferase occurred in about one-third of them. These results were not much different from those reported in other countries.

In 42 alcoholics biopsy of the liver was done during the period of abstinence and the following biochemical investigations were carried out at the same time: AspAT, A1AT, GGTP, alkaline phosphatase activity, total serum protein level, protein electrophoretic fractions, levels of urea and fibrinogen, prothrombin index and white blood cell count. In these investigations determination of transaminase activity was found to be most sensitive in the detection of hepatocellular damage. In some patients no abnormalities were found in biochemical investigations despite presence of high-grade changes in the liver in histological examination.

The mean values of body mass index, haemoglobin A1, serum protein, total lipids, triglycerides, lactate dehydrogenase, alkaline phosphatase, amylase and beta-glucuronidase and heart rate and blood pressure and blood urea levels of Libyan diabetic patients with secondary complications are significantly higher than those of the patients without secondary complications. However, the mean values of fasting blood glucose, serum cholesterol and beta-N-acetylglucosaminidase of patients without complications are higher than those of the patients with secondary complications. The duration of diabetes in patients with secondary complications was 10.2 +/- 1 years while that of patients without complications was 5.2 +/- 0.65 years. The significance of these results is discussed.

In the mouse experimental model the effect of two different methods of myeloablation-immunosuppression treatment administered as preparation for bone marrow transplantation was studied, also the effect of animal's age on the values of the essential biochemical parameters in the serum and on the body weight of the animals was assessed. The recipients were prepared for the transplantation with total-body irradiation and administration of cyclophosphamide (radio-chemotherapy) or administration of busulphan with cyclophosphamide (combined chemotherapy). Transplantation was done in animals aged 2.5 and 12 months. In all studied animals serum protein and calcium levels were decreased after the transplantation and the uric acid level was transiently raised. In the older mice a short lasting increase in the serum levels of bilirubin, alkaline phosphatase, AST and ALT was noted. However, no changes were found in the results biochemical investigations which could have been related to the method of myeloablation and immunosuppression, apart from slight hypercholesterolaemia which developed about 30 days after the operation in mice prepared by radio-chemotherapy. However, after a year lower body weight was observed in young mice prepared for the procedure with radiation exposure and cyclophosphamide, as compared to those receiving combined chemotherapy. Clinical aspects of these disturbances are discussed.
