Twenty calves were infected with 1000 metacercariae of Fasciola hepatica, the activities of 10 enzymes in plasma or serum were assayed and concentrations in serum of proteins, urea and bilirubin were determined. These values were compared with control data obtained from 14 uninfected calves. Aspartate aminotransferase, lactate dehydrogenase, sorbitol dehydrogenase, glutamate dehydrogenase, ornithine carbamoyl transferase and gamma-glutamyl transpeptidase activities increased in infected calves. Total serum protein increased, albumin decreased, globulin increased and the albumin/globulin ratio was decreased in infected calves. Plasma alanine aminotransferase, leucine aminopeptidase, alkaline phosphatase and cholinesterase activities and serum concentration of urea and bilirubin were unaffected. It was concluded that glutamate dehydrogenase and gamma-glutamyl transpeptidase were the most sensitive indicators of liver cell damage in fascioliasis.

Of 101 consecutive hospitalised diabetic patients, 29 had elevated serum enzyme activities attributable to recognized clinical entities; 17% of the remainder had raised alkaline phosphatase (AP) activity, 15% had raised aspartate aminotransferase (GOT) activity, and 12% raised lactate dehydrogenase (LDH) activity in serum. Ketoacidosis and death within 3 months were commoner among patients with elevated serum enzyme activities than among those with normal enzymes. Study of 200 consecutive new untreated diabetics when first seen at an out-patient clinic revealed 15 with clinically explainable abnormal serum enzyme activities. Of the remainder, 11% had raised AP activity, 12% raised GOT activity, and 21% raised LDH activity in serum; these patients tended to have higher blood sugar concentrations than the subjects with normal serum enzymes. These abnormalities seem to be an intrinsic feature of diabetes mellitus which do not relate to duration, complications, or treatment of the disease. They do not seem to be directly related to hepatic involvement.

The twenty-four hour variation in concentration and output of total protein, lactate dehydrogenase and alkaline phosphatase has been studied in the peripheral lymph from the legs of 5 healthy volunteers over a period of five days. The highest concentration of these proteins was found in lymph collected during the first two hours after a night's rest. During the day a continuous decrease in concentration occurred without any direct correlation to lymph flow. The variation in lymph protein concentration between early morning and late day was about 40%, lactate dehydrogenase and alkaline phosphate about 90% and 45% respectively.

Changes in normal human leg lymph protein concentration, output, and lymph flow/lymph protein concentration relationship, as well as lactate dehydrogenase and alkaline phosphatase activity were followed during procedures known to increase capillary filtration as venous stasis, muscular exercise and warming of tissues. Lymph flow increased by 83% during two hour ergometer cycling, and by 117% during two hour warm water foot bath. During a two hour period of venous stasis lymph flow dropped by 50%. There was an increase in lymph flow during the rest period following all three types of experiment, most pronounced after foot warming. An inverse relationship between the lymph flow rate and lymph protein concentration was found. Lymph enzymes followed the same pattern of changes as total protein.

I evaluated the diagnostic value of routinely ordered liver-function tests in 175 biopsy-proven cases of hepatic disease by use of stepwise discriminant analysis. The tests studied-total and "direct" bilirubin, alkaline phosphatase, lactate dehydrogenase, and aspartate aminotransferase-correctly classified 45-73% of cases, depending on the homogeneity of the diagnostic groups. Aspartate aminotransferase and alkaline phosphatase were the best discriminators. When all tests were used in the most homogeneous groups (tumors, cirrhosis, and hepatitis), there was a stepwise improvement in diagnostic accuracy from 51 to 73%.

The values of a number of biochemical variables have been studied before and after a 50-gram load of glucose orally. Reductions which were statistically significant were found for sodium, potassium, urea, total protein, albumin, calcium, phosphorus, urate, bilirubin, alkaline phosphatase, but not for bicarbonate, creatinine, creatine kinase, lactate dehydrogenase, aspartate aminotransferase, cholesterol, triglyceride or chloride. The magnitude of the changes was generally not great, but could be clinically appreciable. The differences may need to be taken into account in comparing population studies.

The stability of total protein and various enzyme and electrolyte analytes in numerous pools of lyophilized quality control sera is evaluated. Using data obtained between 1973 and 1976 from Regional Quality Control Programs utilizing the Quality Assurance Service of the College of American Pathologists, monthly group mean values are studied as a function of time, by means of linear regression analysis. In the 28 pools studied, unstable analyte-pool combinations were detected in approximately 35% of the cases. Total protein was the most universally stable. In a large percentage of pools, minimally increasing concentrations of sodium, chloride, and potassium were found, while inorganic phosphorus decreased in the majority of pools. In pools with changing enzymatic activiteis, alkaline phosphatase tended to increase and creatine phosphokinase generally decreased. Changes in levels of calcium, serum glutamic oxaloacetic transaminase, and lactate dehydrogenase were inconsistent. Changes in analyte concentration were judged in relation to the precision (SD) with which the analytes were measured. The ratios of rate of change in analyte value to SD were lower for electrolytes than for other analytes.

Human erythrocyte ghosts were solubilized in a low ionic strength medium containing 1% Triton X-100 and subjected to electrophoresis in polyacrylamide gels containing Triton X-100. Five major bands were stained with Coomassie Blue, all except one band being heterogenous when re-electrophoresed in gels containing sodium dodecyl sulphate. It was possible to detect acetylcholinesterase, non-specific esterase, ATPase, alkaline phosphatase, 5'-nucleotidase, glyceraldehyde-3-phosphate dehydrogenase, lactate dehydrogenase, and aldolase activities on the Triton-containing polyacrylamide gels. Two of the enzymes, ATPase and 5'-nucleotidase, showed substantial inhibition by Triton X-100 in quantitative studies. This appears to be a useful method for studying membrane enzymes in normal and pathological red cells.

The lactate and pyruvate levels, as well as acid and alkaline phosphatase, lactate dehydrogenase, glucose-6-phosphate dehydrogenase, glutaminic acid-oxalacetic acid transaminase and aldolase levels of rat liver homogenizates were measured at 24 degrees C and 38 degrees C during 120 min ischaemia from 0 to the 120th min. With the exception of transaminase and aldolase, the other enzymes were also enzyme-histochemically studied. The early lesions of the liver can be detected, both the quantitative laboratory tests and enzyme histochemical studies. The deviations from normal, observed at 24 degrees C between the 60th and 100th min, and at 38 degrees C between the 30th and 60th min, might be signs of irreversible lesions. Fractionated study of the liver homogenizate improves the assessability of enzyme determinations. In the course of "warm" ischaemia, the liver lysosomal lesions are early symptoms. Parallel to the breakdown of aerobic glycolysis lactic acid, fermentation, and an active pentose phosphate cycle can be detected. Quantitative testing of the liver homogenizate and enzyme histochemical observation of the hepatic tissue, might be a suitable method for the assessment of ischaemic liver lesions.

Catalase activity in leucocytes was found to be half the normal value in hypocatalasemia and extremely low in acatalasemia. Glucose-6-phosphate dehydrogenase activity in erythrocytes was not significantly different between normal, hypocatalasemia and acatalasemia in three families of acatalasemia, but in one family lower activities than normal were found in hypocatalasemia and actalasemia erythrocytes. Other enzyme activities in blood, such as alkaline phosphatase, lactate dehydrogenase, glutamic oxaloacetic and glutamic pyruvic transaminases were not significantly different between normal subjects, hypocatalasemia and acatalasemia.
