The development of toxicity to 4'-demethylepipodophyllotoxin-9-(4,6,-O-thenylidene-beta-glucopyranoside) an epipodophyllotoxin with oncolytic activity, was characterized in mice treated three times at 3-day intervals with 10 mg of drug i.p. per kg of body weight. Changes in organ function and general metabolism were determined by measuring 18 constituents of blood for up to 10 weeks after drug administration. The results indicate three distinct phases of toxicity to 4'-demethylepipodophyllotoxin 9-(4,6-O-2-thenylidene-beta-glucopyranoside). Acute toxicity developed within the first 10 days and was expressed by a depressed hematocrit and elevated plasma levels of glutamate-pyruvate transaminase, glutamate-oxaloacetate transaminase, lactic dehydrogenase, amylase, lipase, and uric acid. By 4 weeks, levels ahd returned to normal. The acute phase was followed by a chronic phase, which was characterized by progressive decreases in plasma levels of glucose, cholesterol, albumin, and total protein. Finally, about 7 weeks after treatment, a terminal phase indicated by correlated increases in glutamate-pyruvate transaminase, glutamate-oxaloacetate transaminase, lactic dehydrogenase, and blood urea nitrogen became apparent. Plasma levels of creatine phosphokinase, calcium, inorganic phosphate, total bilirubin, ketones, and alkaline phosphatase did not change. Although the pancreas liver and marrow were all affected during acute toxicity, boserved changes in blood components during the chronic and terminal phases correlate best with continued hepatotoxicity. The present evidence on delayed toxicity to 4'-demethylepipodophyllotoxin 9-(4,6-o-2-thenylidene-beta-D-glucopyranoside) is most compatible with irreversible hepatotoxocity which leads to metabolic deficiencies and terminates in death of mice.

Glycylprolyl beta-naphthylamidase activities in sera from 40 normal subjects (18-81 years) were: 22.6 +/- 0.9 (S.E.) (11.8-38.2) I.U./1 serum at 37 degrees C. The enzyme activities did not differ significantly with age between the younger group under 40-years-old and the older group over 40-years-old. Males, especially under 40-years-old, had slight but significantly higher activities than females. The levels were decreased in patients with gastric cancer. The levels were elevated in patients with hepatobiliary diseases, and had significant correlations with the results of the serum tests in hepatic diseases such as glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase, alkaline phosphatase and total bilirubin, but had no correlation with serum lactate dehydrogenase. In cellulose acetate electrophoresis, normal sera had a single peak at the beta-globulin region, but the sera in hepatitis or liver cirrhosis showed not only an increase in the normal peak at the beta-globulin region but also the appearance of the other one or two new peaks in the alpha1 and alpha2-globulin regions.

We have recently utilized a prototype model of the Beckman Enzyme Activity Analyzer System-TR in our laboratory measuring various serum enzyme activities which include: alkaline phosphatase (ALP), E.C.3.1.3.1; creatine kinase (CK), E.C.2.7.3.2; hydroxybutyrate dehydrogenase (HBD), E.C.1.1.1.30; lactate dehydrogenase (LD), E.C.1.1.1.27; aspartate transaminase (AST), E.C.2.6.1.1; and alanine transaminase (ALT), E.C.2.6.1.2. Precision was found to be good. Sample activities could be measured as high as 1000 IU/1. The carryover studies fell within 2 SD of the means of the enzyme control studies. Coefficients of variation for ALP and CK were in the ranges of 0-40-2-14% and 0-52-4-30%, respectively. Correlation studies were done with GemSAEC and Gilford 300 N Spectrophotometer and the results were accurate, precise, and reproducible.

12-Keto oleic acid, possibly one of the oxidation products of long-chain, unsaturated fatty acids, was added to the feed of weanling male rats at the 1% level. Their growth curves, tissue weights, plasma alkaline phosphatase, GOT, and GPT activities, and plasma and liver lipid (cholesterol, triglyceride and phospholipid) levels were investigated and compared with those of weanlings fed a vitamin E deficient diet. Both the diet containing 12-keto oleic acid and the diet deficient in vitamin E decreased the growth rate of body weight and tissue weight, and increased the liver triglyceride and cholesterol levels. Parallel with these, increased hemolysis and stimulation of lipid peroxidation and fluorescent production in the liver homogenate were observed. Elevated plasma alkaline phosphatase and GOT activities which may be considered to be due to a functional disorder of the liver were also observed.

The activities of aspartate aminotransferase (GOT), alanine aminotransferase (GPT), alkaline phosphatase (alkP), creatine kinase (CPK), and ornithine carbamoyltransferase (OCT) were determined in liver, heart, skeletal muscle, brain, kidney, lung, spleen, adrenals, pancreas, thyroid, thymus, and red cells of 56 bovine fetuses varying in gestational age from 115 to 255 days. The tissue aminotransferase activities were the most variable with gestational age. The GPT activity of liver, kidney, spleen, and red cells and the GOT activity of red cells decreased with fetal age. The GPT activity of heart, brain, and skeletal muscle and the GOT activity of adrenal, brain, and skeletal muscle increased with fetal age. Increasing activities were also described for adrenal and brain alkP and for brain and skeletal muscle CPK. In contrast, the OCT activities were fairly constant for each tissue as a function of gestational age.

The authors report the clinical, biochemical, histological and etiologic characteristics of 24 patients with the syndrome of benign intra-hepatic post-operative cholestasis. Jaundice appeared early in the post-operative period, from the first to the 12th post-operative day. All patients had received blood transfusions. In 23 patients, the post-operative course was complicated, chiefly by local infection or septicemia. Hyperbilirubinemia ranged from 2 to 28 mg per 100 ml and was mainly conjugated; serum alkaline phosphatase activity was normal or moderately elevated; in 3 patients, it was markedly elevated; serum glutamic-pyruvic transaminase activity was normal on 7 patients, moderatly increased in 15, and markedly increased in one. Liver histology was normal in 6 patients, and showed minimal lesions (cholestasis and slight portal inflammatory changes) in 3. Jaundice did not appear to modify the final outcome. It appears to be due both to increased production of bilirubin (as a result of blood transfusions) and to decreased excretion of bilirubin by the liver (as a result of the surgical operation and of infection).

18 women were treated with Deposition (4th, 11th, and 18th cycle day each, 1 mg 17alpha-Ethynyl-3-isopropylsulfonyloxy-Estradiol; 25th cycle day, 10 mg norethisterone acetate). When these medicines were taken, the activities of aminotransferases, alkaline phosphatase and alpha-amylase, cholesterol, total bilirubin and proteins of the serum, TTT, and indocyanine green were measured. A little significant decrease of the activity of alaninamino transferase (GPT) was to be stated. Whereas at the end of the 6th cycle the TTT as well as the contents of total proteins and albumin, showed a little significant decrease and the contents of alpha-2-globulin, beta-globulin as well as cholesterol were statistically shown to grow. The indocyanine green elimation was longer at the end of the 6th cycle without any pathological worth from the clinical point of view being proved.

In the serum of 40 male and 40 female rats the following parameters were determined: Sodium, potassium, creatinine, chloride, calcium, inorganic phosphorus, glucose, urea, protein, cholesterol, bilirubin, lipids, alanine amino-transferase, alkaline phosphatase and leucine arylamidase. The analyses were carried out in the same rats both after continuous feeding, and after a 24-hour fasting periods spaced at intervals of 3- to 4-weeks. The concentration of glucose and the activities of alanine aminotransferase and alkaline phosphatase were higher after feeding than after fasting, and in most cases these differences were statistically significant. The concentration of lipids tended towards increased values. The other parameters examined were slightly or not influenced by the time of the foregoing feeding.

The transfer of male dogs from lowlands to an altitude of 3370 m was accompanied by hypoproteinemia and reduction of albumins and beta-globulins, stable increase of activity of alanine aminotransferase, decrease of activity of alkaline phosphatase and content of phosphate. This can be interpreted as a manifestation of adaptive changes of metabolic processes to altitude hypoxia. The return of dogs to lowlands was accompanied by the normalization of the changes during the first 20 days.

The following enzymes were determined in the serum and plasma of man, dog and rat: alanine aminotransferase, asparate aminotransferase, alkaline phosphatase, lactate dehydrogenase and alpha-hydroxybutyrate dehydrogenase. The enzyme assays were performed on an Eppendorf-Enzymautomat 5010 using optimised conditions at 25 degrees C. The enzyme-activities changed by variable amounts during standing of the blood. This concerned mainly lactate dehydrogenase, alpha-hydroxybutyrate dehydrogenase and aspartate aminotransferase in the serum of the rat. In human serum and in dog serum, and in the plasma of man, dog and rat this effect was only less pronounced.
