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.

A group of male rabbits was partially hepatectomized, while another group was administered intraperitoneally with aqueous thioacetamide (TAA) solution (2 mg/kg body weight/alternate day) after partial hepatectomy (PH). The blood samples of animals of both groups were collected on day 10, 15, 20, 30, 60 and 90 following PH and used for various haematological and biochemical analyses. The haemoglobin content decreased significantly within 10 days of PH and gained significant increase 3 months after. An abrupt increase was, however, recorded after TAA treatment. All the enzymatic activities remained unchanged except for that of lactate dehydrogenase (LDH), which was elevated 87% during the first 10 days of PH. The serum glutamate pyruvate transaminase (SGPT) activity was raised 2.8 times. It was only two months after the operation that the alkaline phosphatase (AP) and LDH activities showed signs of inhibition. The only enzyme affected by TAA treatment after the PH was AP activity, which was inhibited drastically within 15 days after operation. It was concluded that, except for the AP activity and bilirubin and urea content, that essentially decreased in the presence of TAA during the first 15-20 days of experimental period, all the other haematological and biochemical parameters got normalized more quickly in the presence of TAA.

Orthotopic hepatic transplantation was performed upon 29 dogs. Four dogs received no immunosuppressant, 12 received cyclosporine and 13 received azathioprine. Dogs treated with cyclosporine at a dose of 20 milligrams per kilogram yielded histologic and functional data indistinguishable from those of the dogs in the sham transplant group. Histologic evidence of rejection consistently appeared when the dose was decreased to 10 milligrams per kilogram but was reversed upon resuming the administration of the higher dosage. Serum levels of bilirubin and hepatic enzymes, serum glutamic-oxalacetic transaminase, serum glutamic-pyruvic transaminase and alkaline phosphatase did not correlate with the development or resolution of histologic evidence of rejection in dogs receiving cyclosporine. Dogs receiving cyclosporine for 60 days had a prolonged survival when the drug was stopped, whereas the dogs receiving such therapy for less than 60 days did not have a prolonged survival period.

The protective activity of 1,2-bis(3,5-dioxopiperazin-l-yl)propane (ICRF-187) and dimethyl sulfoxide (DMSO) was tested against acetaminophen-induced hepatotoxicity. Male Syrian golden hamsters injected intraperitoneally between 18:00 h and 20:00 h for 2 consecutive days with acetaminophen (N-acetyl-p-aminophenol) (300 mg/kg) displayed signs of hepatotoxicity as evidenced by increases in enzyme activity and cellular damage. Forty-eight hours after the second acetaminophen dose, the activities of serum glutamic-pyruvic transaminase and alkaline phosphatase were increased compared with levels found in hamsters given only saline. In addition, hepatocellular necrosis was evident in acetaminophen-treated animals. ICRF-187 (300 mg/kg) given 1 h before acetaminophen attenuated the increases in enzyme activities, and both DMSO (7.3 g/kg) and ICRF-187 reduced the incidence and severity of acetaminophen-induced hepatocellular injury. Both ICRF-187 and DMSO are capable of altering free radical-mediated toxicity in other experimental systems. Whether these compounds reduce acetaminophen-induced liver toxicity by a similar mechanism remains to be determined.

As part of a six-month prospective study of the effects of neonatal thymectomy in the spontaneously diabetic BB Wistar rat, activities of the following enzymes were determined: alkaline phosphatase (AP), lactate dehydrogenase (LDH), creatine phosphokinase (CPK), glutamic-oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT) and UDP-galactosyltransferase (UDPG). In prediabetics, AP and LDH levels were higher than in sham-operated, non-diabetic controls; however, this increase was seen in nearly all diabetes-prone BB rats, diminishing the usefulness of these changes in discerning potential diabetics from asymptomatic, diabetes-prone rats. After onset of the syndrome, there was a striking elevation of AP values in all diabetics with no similar alteration in asymptomatic, diabetes-prone rats suggesting this was a diabetes-related phenomenon. By contrast, UDPG was the only enzyme to decrease immediately following the onset of the syndrome. Both UDPG and AP levels correlated with blood glucose, the former negatively and the latter positively, suggesting a close relationship with changes occurring after onset of the syndrome. The remaining enzymes increased only in a portion of diabetics alone (GOT, GPT) or in a portion of both diabetics and asymptomatic, diabetes-prone BB rats (LDH, CPK).

A total of 466 patients were treated with cefoperazone. The drug was usually administered by drip infusion of 2 to 4 gm/day. Therapy was described as markedly effective and moderately effective in 64 of 77 patients (83.1%) treated for urinary tract infections; 253 of 316 patients (80.1%) treated for respiratory infections; 37 of 48 patients (77.1%) treated for liver biliary duct infections; ten of 16 patients (62.5%) treated for septicemia; and seven of nine patients (77.8%) being treated for other infections. Overall, cefoperazone was effective 79.6% of all patients treated. With respect to bacteriological activity, the overall eradication rate for gram-negative organisms (including Pseudomonas aeruginosa, Klebsiella sp, Escherichia coli, Haemophilus influenzae, Enterobacter sp, and Proteus sp) was 81% (182/225) and for gram-positive (Staphyloccocus aureus, Streptococcus pneumoniae and Streptococcus faecalis) 90% (36/40). Of 205 patients who failed to respond to previous antibiotic therapy, 67.8% were treated effectively with cefoperazone. Side effects, such as skin eruption, pyrexia and diarrhea, occurred in only 4.8% of patients treated, while laboratory abnormalities, such as elevated glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase, alkaline phosphatase, and eosinophil values, occurred in only 6.4% of the treated patients. None of these abnormal values were of clinical significance.

The aim of this work is to evaluate the concentration of serum bile acids (SBA) as an index of impaired liver function in systemic lupus erythematosus (SLE) patients versus usual laboratory tests of hepato-biliary system diseases. In patients with SLE the mean fasting SBA concentration was 9.6 +/- 1.4 mumol/L; in normal subjects the concentration was 2.9 +/- 0.6 mumol/L (P less than 0.01). In patients with SLE, mean gamma-glutamyl transpeptidase (GGTP) concentration was 31.5 +/- 5.9 mU/ml versus 10.05 +/- 1.1 mU/ml in controls (P less than 0.01). The bromsulphalein (BSP) excretion test, 45 minutes after injection, was 6.8 +/- 1% in SLE patients versus 2.8 +/- 0.4% in controls (P less than 0.02). No significant difference was found between these two groups of subjects with respect to leucine aminopeptidase (LAP), alkaline phosphatase (AlPh), glutamic-oxalacetic transaminase (SGOT), glutamic-pyruvic transaminase (SGPT), bilirubin serum rates. SBA rate was abnormal in 50% of the SLE patients; GGTP rate and the BSP excretion test were abnormal in 38% and 27% respectively. Our findings show the presence of an actual liver impairment in SLE patients, significantly demonstrated by fasting SBA concentration, GGTP rate and BSP excretion test. Other liver function tests are less useful in evaluating hepatic damage in SLE.

Injectable progestogen, norethisterone enanthate (NET-EN, 200 mg/ml at 60 day intervals), was administered to 150 women for 2 years as their method of contraception. Blood levels of acid phosphatase, alkaline phosphatase, glutamate pyruvate transaminase, glutamate oxaloacetate transaminase, acetylcholinesterase (AChe), sialic acid were determined in all subjects to ascertain whether NET-EN therapy causes any adverse metabolic effect or damage to the functional status of the liver. NET-EN contraception did not alter the liver function enzymes but there is a significant increase (P0.001) in AChE activity after 2 years. Serum sialic acid level showed a transient increase up to 1 year, which however returned to control level later. The mechanism responsible for these changes and whether the rise in sialic acid and AChE activity are related to any pathological condition remain unclear at this stage.

Hepatic transport of indocyanine green (ICG) was examined in dogs chronically intoxicated with dimethylnitrosamine (DMN) (2 mg/kg) intraportally once a week for 6 weeks. In pathophysiological consequences, significant increases (p less than 0.05) were shown in both glutamic-pyruvic transaminase (GPT) and total plasma bile acids, but no significant difference was shown in body weight, liver wet weight, glutamic-oxaloacetic transaminase (GOT), plasma alkaline phosphatase activity, total plasma protein, and total plasma bilirubin. By histologic examination of livers from intoxicated dogs, increased fibrosis in periportal, perisinusoidal, and especially pericentral areas, with loss of normal architecture, was observed. Partial fibrous bridging between periportal and pericentral areas was also demonstrated, but extensive pseudolobulation with regenerative nodules was not observed. The portal venous pressure of the intoxicated dogs was increased by approximately 50% of that of control dogs. In intoxicated dogs, delays were shown in both plasma disappearance and biliary excretion of ICG and significant decreases were observed in the pharmacokinetic parameters k12 (plasma to liver transfer rate constant), V2 (distribution volume of liver compartment), and CLtot (total body-plasma clearance), while a significant increase was observed in k23 (intrahepatic diffusion and transport rate constant); the V1 (distribution volume of plasma compartment) was not altered. From these findings, it is suggested that the decrease in the intrinsic clearance of ICG for the hepatic uptake process might explain the decrease in ICG uptake rate into the liver which was observed in the DMN-intoxicated dogs. Dogs chronically intoxicated with DMN might be a good model for studying hepatic dysfunction.

The effect of nickel on cadmium nephro-toxicity and hepato-toxicity in rats was investigated. The administration of nickel (6 mg per kg, i.p., three days) or cadmium (6 mg per kg, i.m., once) significantly enhanced the urinary excretion of alkaline phosphatase (ALP), lactate dehydrogenase (LDH), glutamate oxaloacetate transaminase (GOT), amino acids, and proteins. In addition, it increased the activity of serum ALP, GOT, and glutamate pyruvate transaminase (GPT). These biochemical alterations in urine and serum were used as a measure of kidney and liver damage. Cadmium-induced enzymuria, proteinuria, amino aciduria and increase in the activity of serum enzymes were significantly less marked in animals pretreated with nickel than in controls. However, the accumulation of cadmium in kidneys and liver and its urinary excretion were unaffected by nickel pretreatment. The results suggest protection by nickel against cadmium nephro- and hepato-toxicity.
