A case report of cholestatic jaundice in a 25 year old woman, who had had jaundice at age 4 years, and had taken Stediril (a combined oral contraceptive) for 1 month, implicates either the pill or a possibly hereditary hyperlipidemia. The jaundice developed in 2 weeks with vomiting, epigastric pain, anorexia, then discolored urine and feces, and intense pruritus. On hospitalization the patient had moderate bilirubinemia (56 mg/1), low alkaline phosphatase (13 U.K.) and slightly high serum glutamate pyruvate transaminase (270 U.W.). There were elevated serum cholesterol (3 gm/1), triglycerides (2.05 gm/1), total lipids (10.6 gm/1), and a definitely increased pre-beta lipoprotein, suggesting hyperlipidemia type IV (Frederickson classification). Liver biopsy showed fibrosis of the portal spaces lymphocytic infiltration, canalicular and intrahepatocytic thrombi. On laparoscopy the liver had a regular lower border, normal volume color and surface. Albumin, prothrombin and flocculation tests were normal. The patient's jaundice lasted about 1 month, then liver function slowly improved, although pruritus remained intense. Probably this jaundice was due to oral contraceptives, in a patient predisposed either by jaundice in childhood or endogenous hyperlipidemia.

Plasma lipid concentrations in NAR (Nagase Analbuminemia Rats) of 4 to 52 weeks old were examined. Plasma enzymes of NAR were also measured in relation to liver function. The concentrations of total lipid, total cholesterol, phospholipid and triglyceride tended to be increased in NAR, while that of non-esterified fatty acid (NEFA) was decreased. The lipid levels (except NEFA) were especially high in female adult NAR, and they were increased with aging. The effect of 17 beta-estradiol or testosterone administration on serum lipid concentrations was studied in gonadectomized NAR. Administration of 17 beta-estradiol to gonadectomized NAR increased lipid concentrations, while testosterone administration did not affect lipid levels. The effect of albumin injection on lipid concentrations in female NAR was also investigated. Albumin treatment to female NAR lowered serum lipid concentrations. Plasma glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, lactate dehydrogenase and leucine aminopeptidase activities were higher in NAR than in normal rats. Plasma alkaline phosphatase and cholinesterase activities of NAR were similar to those of normal rats.

The chemical measurements on our Technicon SMAC of lipemic sera before and after clearing lipemia by ultracentrifugation showed that uric acid, creatinine, carbon dioxide, calcium, phosphorus, potassium, and alkaline phosphatase were not affected significantly by lipemia, whereas sodium, urea, glucose, chloride and total protein showed small but significant increases with averages of less than 1.9 percent. Albumin showed a significant decrease of 1.2 percent. In contrast, the results for the enzymes, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) showed striking differences between pre- and post-centrifuged sera in a number of specimens. With lactate dehydrogenase, thirty-two of fifty specimens registered an increase in activity while with the aminotransferases, thirty-five and forty-one out of fifty specimens showed a decrease in aspartate aminotransferase and alanine aminotransferase activities, respectively. Although much of the lipemic interference can be explained by the volume displacement of serum by lipids or by interference by lipemia with colorimetry, the anomalous effects observed with the enzymes indicate the possibility of other, as yet, undetermined factor(s).

The effects of race, age, and sex on selected blood components for 429 black and white adults over 34 year in southwest Mississippi were studied. Fasting blood was collected early in the morning. Whole blood was used for the determination of hematocrit and hemoglobin. The sera were used for the analysis of iron, glucose, triglycerides, cholesterol, vitamin C, alkaline phosphatase, and protein and its fractions such as albumin, alpha-, beta-, and gamma-globulins. The data of whites versus blacks, males versus females, and those under versus over 60 years were compared. A significant racial difference was observed for all selected blood components except alpha-1-globulin, cholesterol, and alkaline phosphatase. Albumin, alpha-2-globulin, hemoglobin, hematocrit, serum iron, triglycerides, and vitamin C were significantly higher in whites than in blacks and total protein, beta-1- and gamma-globulins and glucose were significantly higher in blacks than in whites. Males had higher levels of alpha-1- and gamma-globulins, hemoglobin, and hematocrit, and females had higher levels of cholesterol and alkaline phosphatase. Those 60 years and over had higher gamma-globulin and alkaline phosphatase, while adults under 60 years had higher hematocrit. Although results of this study showed significant differences between the races for certain blood parameters and suggest that these differences should be considered in determining guidelines for nutritional evaluation and criteria of diagnosing diseases, further studies are needed to determine the contributions of environment, economic status, and nutritional status to these differences.

The etiology of osteoporosis associated with rheumatoid arthritis (RA) is unknown. We studied the calcium and vitamin D metabolism in 143 women with RA (mean age 50.7 years). Albumin corrected serum calcium was normal. Serum alkaline phosphatase was increased in 29 percent of cases. Serum vitamin D levels were frequently very low. In 16 percent of the RA patients serum 25(OH)D concentration was below 12.5 nmol/L, which is arbitrarily considered as the limit of vitamin D deficiency osteomalacia. In the winter season 73 percent of the patients had serum 1,25(OH)2D levels below the seasonally adjusted normal range. The lowest values were found in patients with high disease activity. We suggest that there is a disturbance in vitamin D metabolism in RA. This might play a role in osteoporosis associated with RA.

Effects of storage at room temperature (23-25 degrees C) and refrigeration (4-5 degrees C) on various biochemical constituents of camel serum were investigated. Albumin, globulin, calcium, phosphorus, cholesterol, aspartate aminotransferase (AST), alkaline phosphatase (AP) and gamma glutamyltransferase (GGT) did not change over 9 days when stored at 4-5 degree C. At 4-5 degree C, creatinine, iron and glucose in camel sera remained stable for 6 days; total protein for 7 days; and blood urea nitrogen for 8 days. Decreased activities in creatine kinase (CK), lactate dehydrogenase (LDH) and alanine aminotransferase (ALT) were apparent after 1, 6, and 7 days, respectively. At room temperature, total protein, albumin, globulin, calcium and phosphorus were stable throughout the 9 days. Changes in glucose and iron occurred after 3 days. Stability at room temperature for LDH was 1 day; AST, 3 days; GGT and ALT, 6 days; and AP, 8 days. CK activity had already declined by 4 hours and by 9 days, only 34% activity remained.

Discriminant function analysis has been used to investigate the relative value of six biochemical parameters (plasma ferritin, C-reactive-protein, bilirubin, alkaline phosphatase, glutamic oxaloacetic acid transaminase and albumin) in the diagnosis of liver disease. This was done among four groups totalling 70 subjects including healthy controls and patients with acute viral hepatitis, liver cirrhosis and primary hepatocellular carcinoma. Albumin had most value in distinguishing between groups, followed cumulatively by ferritin, alkaline phosphatase, C-reactive protein, bilirubin and glutamic oxaloacetic acid transaminase. However, if data on albumin, alkaline phosphatase, bilirubin and glutamic oxaloacetic acid transaminase had already been routinely collected, there would be no advantage in collecting data on ferritin and C-reactive protein. Any four of the six parameters would be of about equal value in distinguishing between diagnostic groups. When the data on all six biochemical parameters was combined in an optimum way, about 66% of all individuals could be correctly assigned to one of the four groups using biochemical markers alone. While the control subjects and patients with acute viral hepatitis formed a relatively well defined, tight cluster (apart from two patients with acute viral hepatitis), patients with liver cirrhosis and primary hepatocellular carcinoma were almost indistinguishable, using these biochemical parameters. If the latter two groups were pooled, then about 86% of subjects could be correctly classified.

Hepatic Metastases (HM) from colorectal cancer represents one of the main problems of oncologic treatment: from 80 to 90 percent of patients undergo chemotherapy and a minority hepatic resection. The natural history of patients with unresectable HM has been recently investigated by uni and multivariate analyses; the percentage of hepatic replacement, the stage and grade of primary colorectal tumours, alkaline phosphatase and the presence of extrahepatic disease proved to be the most important independent prognostic factors. Albumin and carcino-embryonic antigen (CEA) levels, age and weight loss of patients were also prognostic. The groups of patients with more favourable factors had a median survival ranging from 21 to 35 months, in contrast to a median survival of 4 to 8 months for those with adverse factors. The outcome of more than 3400 patients submitted to hepatic resection, has been investigated. At multivariate analysis twelve variables resulted independently related to prognosis: stage of primary tumour, extent of liver involvement and presence of extrahepatic metastases were considered to be the most important. The knowledge of prognostic factors is extremely important in selecting patients candidated to various treatments, to interpret the results and to plan new therapeutic strategies.

Ciprofibrates (racemate and both enantiomers, Raccip, R- and Scip) were administered orally in doses of 1 and 10 mg/kg once daily over 28 days to male inbred Fischer 344 rats, age 90-110 days at the beginning of the experiment. Body mass gain was observed in all groups. The 1 mg groups showed almost no difference to the control group. The 10 mg groups exhibited less body mass gain, most pronounced in the Scip group. Liver masses were increased in a dose dependent manner up to more than 200%, only the 10 mg Scip group was not significantly different from the 1 mg group which exhibited an increase in liver weight to about 175%. Also the kidney weights increased to 130%, whereas thymus and spleen weights were decreased in the high dose groups. Liver microsomal cytochromes P450 (P450) concentrations were not altered in the 1 mg groups and distinctly lowered in the 10 mg groups. Ethoxyresorufin and ethoxycoumarin O-deethylations were lowered in all experimental groups in a dose dependent manner, after administration of the high doses down to 30% of the control levels or less. Pentoxyresorufin O-depentylation, however, was increased in all 1 mg groups. In the high dose groups it was not altered. Ethylmorphine N-demethylation was decreased after administration of the high doses by about 50%, but only Scip decreased this reaction also after administration of the low dose. NADPH/Fe2+-stimulated microsomal luminol and lucigenin amplified chemiluminescence was increased, whereas hydrogen peroxide formation was depressed even by the low doses to 50% of the normal values, to about 25% by the high doses. Microsomal lipid peroxidation, however, was only slightly or not influenced. Glutathion concentrations (in the reduced and the oxidized form) were increased in a dose dependent manner by about 20 to 30%, the concentration of lipid peroxides was not significantly influenced. Thus, the effects of the enantiomers were not different and were similar to those of the racemate. In serum, cholesterol and triglycerides were only moderately lowered. Albumin concentrations were significantly enhanced in all groups, total proteins after 1 mg/kg Raccip only. Serum bilirubins were not altered, and among the indicator enzymes for liver damage only ALAT, alkaline phosphatase and the dehydrogenases were increased, in no case higher than twofold. Histologically distinct effects were seen after administration of both doses, more pronounced after 10 mg/kg, but with no differences between the enantiomers and Raccip: marked hypertrophy of the hepatocytes, reduced staining of the nuclei, strongly acidophilic granulated cytoplama, no basophilia of the cell bodies, loss of glycogen. These changes were most pronounced around the central veins. Hepatocyte apoptoses also were observed. By immunohistochemistry an increased staining was seen for all P450 isoforms tested (1A1, 2B1, 2E1, 3A2 and 4A1), predominantly perivenously and most pronounced after administration of the high doses without differences between Rcip, Scip or Raccip (preliminary results). By electron microscopy a moderate proliferation of peroxisomes after treatment with 1 mg/kg Cips with a ratio between mitochondria and peroxisomes of about 1:1 (controls: 10:1) was observed, and the peroxisomes were a more heterogeneous population. The relative portions of glycogen and both forms of the ER decreased. Treatment with 10 mg/kg Rcip, Scip or Raccip led to a strong increase in the number of peroxisomes, in some hepatocytes the ratio between mitochondria and peroxisomes was 1:3 with an increased heterogeneity among the peroxisomes evidenced by a broad range of electron densities. Most peroxisomes lacked a nucleoid. Thus, the biochemical effects differed only slightly and the morphological effects of the enantiomers were not different and were similar to those of the racemate.

The Lym-1 monoclonal antibody was conjugated with the bifunctional chelating agent 6-[p-(bromoacetamido)benzyl]-1,4,8,11-tetraazacyclotetradecane-N,N ',N'',N'''-tetraacetic acid (BAT), using 2IT as a linker, and radiolabeled with 67Cu to make the radiopharmaceutical, 67Cu-2IT-BAT-Lym-1. Ten patients received a total of 18 doses of 67Cu-2IT-BAT-Lym-1 as targeted, systemic radiotherapy. The beta phase of blood clearance, when corrected for 67Cu decay, was positive or flat, a phenomenon not observed in similar patients treated with 131I-Lym-1. The flat beta phase of blood clearance suggested recycling of 67Cu from 67Cu-2IT-BAT-Lym-1 to another plasma protein. Therefore, the amount of 67Cu transferred from the radiopharmaceutical to CP, Alb, and TF was measured using affinity-purified polyclonal antibodies. The fraction of plasma 67Cu precipitated by anti-human CP increased daily; most blood radioactivity was 67Cu-CP after a median of 4 days (range 2-7 days). The transfer of 67Cu to CP was observed in all patients and was consistent from dose to dose within the same patient. An average of 2.8 +/- 1.5% (range 0.8-7.8%) of the 67Cu dose (%ID) was transferred to CP. The release rate of 67Cu-CP from the liver into the blood was 0.9 +/- 0.4 %ID/day for the first 3 days. The 67Cu-CP effective clearance half-life was 3.7 +/- 0.7 days. Subtraction of the 67Cu-CP activity from the total blood radioactivity yielded a biphasic blood clearance similar to that obtained for patients given 131I-Lym-1. Cu-67-CP increased the AUC for whole blood by 24 +/- 10%. The %ID of 67Cu recycled correlated with GGT, ALT, and alkaline phosphatase levels; r = 0.958 (p < 0.001), 0.857 (p < 0.01), and 0.822 (p < 0.01), respectively. Albumin levels correlated negatively with recycled copper (r = -0.745, p < 0.05). The data suggest that the liver metabolizes 67Cu-2IT-BAT-Lym-1 and recycles a small fraction of the 67Cu, transferring it to CP.
