A female patient developed a recurrent hepatitis-like liver damage after ingestion of a laxative containing 4,4'-(2-quinolyl-methylene)-diphenol-hydrochloride. After cessation of the drug the clinical picture improved. The hyperbilirubinemia decreased and the definitely elevated GOT, GPT, alkaline phosphatase and gamma-GTP became normal. Histologically hepato-cellular damage was seen with intra-hepatic cholestasis. As a cause for these symptoms, resembling those after taking oxyphenisatin-containing preparations, immunological procedures were thought responsible, such as "unpredictable hepatic drug reactions".

Male rats weighing 180-220 g were given CdSO4, 0,4 mg/kg body weight subcutaneously once a week for 6-12 months. The animals were killed after 6, 9, 12 months and following blood serum levels were determined: total protein, albumin, globulin, GPT, GOT, Al.P. and urea. The tissue tissue samples from liver and kidneys were examined histologically (acid and alkaline phosphatase). After 9 months, the difference between values of biochemical indices in the exposed and control groups was statistically significant. It has been found that the observed biochemical indices show correlation with the extent of morphological changes in liver and kidneys. These degenerative changes became more intense in the liver than in the kidneys.

The effect of carbon-tetrachloride poisoning and the protection caused by AMP were studied. A single dose of CCl4 has resulted in a rapid development of a fatty liver, a considerable increase in serum enzymes, glutamic oxalacetic and pyruvic transaminases as well as serum-alkaline phosphatase. Total serum protein showed a tendency to decrease accompanied by a decrease in A/G ratio. Administration of adenosine-5-monophosphate prevented the increase in serum-alkaline phosphatase and increased the A/G ratio. There was, however, a slight but significant decrease in serum GOT and GPT within the 24-hrs. period of study, but it remained still higher than that of the control. AMP lowered liver fat without complete protection against the development of fatty liver.

The effect of daily dermal spray of malathion for four weeks in recommended (0.5 and 1.0 per cent) and higher (5.0 per cent) concentration on various enzymes in Bubalus bubalis species were studied. The higher concentration of 5.0 per cent showed lethal effect after 2 to 3 exposures. The cholinesterase activity in both RBC (RChE) and plasma (PChE) were inhibited with all the concentrations. There was also significant (P less than 0.05) elevation in the activities of serum aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase with 1.0 and 5.0 per cent spray and enzyme activities remained altered even during post-medication. The extent of various biochemical changes were dose and time dependent.

16 patients with chronic liver or haematologic diseases were parenterally given various doses of Desferrioxamine B (DF). Each daily dose of DF (from 1 to 4 g) was given for a 7 days cycle. Liver, kidney and blood functions were investigated at the first and seventh day of each cycle, and 1 and 2 weeks after therapy was stopped. 1 g/day and 2 g/day had no side effects, with the exception of a fall of white blood cell (WBC) count in a single case on 2 g/day. 3 g/day (15 patients) were followed by rises of blood urea, creatinine, alkaline phosphatase and glutamyl-transpeptidase respectively in 4 cases, and by falls of WBC count in 3 cases. 4 g/day (9 patients) caused rises of creatinine, GPT and GOT (1 case) or LDH (1 case), while WBC count dropped in 4 cases. All changes were reversible within one-two weeks. These recorded changes were outside the range of pretreatment values as obtained over the previous four weeks.

Serum gamma glutamyl transpeptidase (GGTP), isocitrate dehydrogenase (ICD), ornithine carbamoyl transferase (OCT), alanine aminotransferase (AlT), aspartate aminotransferase (AsT), and alkaline phosphatase (ALP) activities were assayed in 67 alcoholics and 40 drug dependent patients. Bilirubin, total protein, albumin, and globulin were also measured. GGTP elevation was observed in 48% of alcoholics and in 50% of drug dependents. The incidences of elevated levels of other enzymes were: ICD 39 and 38-7%; OCT 23-7 and 36-1%; AlT 30 and 33%; AsT 24-2 and 21-7%; ALP 10-4 and 5% respectively. Measurement of GGTP is thus more useful as a screening test for involvement of the liver in alcoholics and drug dependent patients than that of the other enzymes.

Minimal liver damage was induced in groups of rats by the administration of three toxicants, viz. carbon tetrachloride, sodium phenobarbitone and orotic acid. Serial blood samples were taken from the animals during the course of the experiment and the plasma levels of a number of enzymes, substrates and metabolites were measured. Liver and kidney samples were also taken at appropriate times after dosing and examined histologically for evidence of drug induced damage. The results of the experiment show that (I) no single test gave unequivocal evidence of liver damage for all three compounds, (II) the conventional liver function tests, alanine transaminase, aspartate transaminase, and alkaline phosphatase, whose plasma activities are usually reported in toxicity studies, were not the most sensitive indicators of the minimal liver cell damage caused by the drugs used in this experiment, (III) knowledge of the intracellular location of the diagnostic enzyme makes it possible to describe, at least in part, the nature of the changes within the liver, (IV) measurement of plasma cholesterol and triglyceride levels can provide information about disruption in lipid metabolism, (V) the times at which blood samples are taken are most important if transient drug effects on the liver are to be detected.

We used the previously described [Clin. Chem. 19, 1114 (1973)] and evaluated [Clin. Chem. 19, 1122 (1973)] computer-controlled instrument system for sequential chemical testing to select and perform tests of hepatic status, to aid the clinician in the diagnosis of liver disease. Results for total bilirubin, aspartate aminotransferase, and alkaline phosphatase obtained from the continuous-flow analysis (SMA 12/60) admission screen were used by the instrument system to determine selectively the values for gamma-glutamyltransferase, alanine aminotransferase, creatine kinase, and total and direct bilirubin. Kit methods for the latter four tests were evaluated on the system; results were similar to manual procedures. A software, enzymatic ratemeter was found to be better than the previously described hardware ratemeter. The follow-up tests of serum prescribed by the system are compared to clinician-prescribed follow-up tests and discharge diagnoses. In 10 of 19 cases, the system and clinician ordered similar follow-up tests; in three cases follow-up differed, and in six cases, the system ordered follow-up tests and the clinician ordered none.

Hepatic function of 80 children aged under 3 years with Plasmodium vivax malaria were studied during the acute attack and 6 weeks after antimalarial treatment. Raised levels of serum aspartate transaminase (serum AST; SGOT), serum alanine transaminase (serum ALT; SGPT), and alkaline phosphatase were observed in 68%, 39% and 46% of cases respectively. AST levels were higher than ALT ones and the mean level of both enzymes was much higher in patients with hepatomegaly. The hepatic dysfunction which these observations reflect is transient, as these enzymes were found to be at their normal levels 6 weeks after treatment. A transient derangement of liver function is thus a common feature of childhood malaria, and hepatic dysfunction takes place to a significant degree even in P. vivax malaria.

Serial liver enzyme and bilirubin concentrations were measured in 100 patients undergoing total parenteral nutrition. Between the eighth and tenth days, serum glutamic-pyruvic transaminase levels rose to 5.4 times pretotal parenteral nutrition levels; serum glutamic-oxalacetic transaminase, 2.8 times; bilirubin, 2.3 times, and lactic dehydrogenase, 1.5 times. These elevations were transient, lasting four to ten days. Biopsies of the liver taken during maximal elevations demonstrated marked periportal fatty change. A second elevation of serum glutamic-pyruvic transaminase, serum glutamic-oxalacetic transaminase, alkaline phosphatase and lactic dehydrogenase occurred in one-third to one-half of those patients receiving total parenteral nutrition for longer than a 20 day period. These elevations were more prolonged, and no biopsies were taken. Amino acid solutions contain conversion products of tryptophan, an amino acid that is unstable in the presence of the preservative sodium bisulfite which is added to all commercially available protein solutions. Infusion of these products into rats, either alone or as part of total parenteral nutrition solutions, resulted in periportal fatty change of the livers identical to that seen in our patients receiving total parenteral nutrition. A toxic effect of tryptophan conversion products in total parenteral nutrition solutions is proposed.
