By the determination of the aldolase, GOT and LDH isoenzymes in the plasma the stage of the acute and chronic hepatitis can be well established. The suitable use of modern statistic methods (multivariate analysis) allows the characterisation, recognition and separation of the groups of disease acute, chronic persisting, chronic aggressive hepatitis and liver cirrhosis as well as the proof of transition forms and severe courses. In acute hepatitides with protracted course under prednisolone therapy in contrast to histology already after a short time changes of the isoenzymes in the hepatic tissue and in the plasma are shown. Apparently the isoenzymes are sensitive indicators of intracellular metabolic processes.

100 patients who got over a virus hepatitis underwent a bicycle ergometry. At the beginning and at the end of the experiment as well as 24 hours after this the isoenzymes of aldolase, GOT and LDH in the plasma were determined by means of kinetic methods. On the basis of the activities of the isoenzymes for the test persons (children and adults of either sex) an arrangement in the groups pathologic--suspicious--normal can be carried out which is compared with the physiologic parameters and the clinic. The results of bicycle ergometry much differ. High effects without pathological changes of the activities of isoenzymes are an objective criterion of the quick, riskless rehabilitation of the test persons.

Hepatocyte membranes destruction in experimental toxic hepatitis caused by heliotrine administration was accompanied by a 10-fold increase in blood serum activity of aldolase fructose-I-monophosphate, a decrease in cytochrome P-450 content, an increase in the rate of cytochrome P-450 inactivation, as well as a decrease in microsomal glucose-6-phosphatase activity. Administration of phosphatidylcholine liposomes decreased the activity of aldolase twofold, which indirectly shows partial reconstitution of liver cell membranes. Phosphatidylcholine protective action is also manifested in an increase in the activity of glucose-6-phosphatase, a microsomal marker enzyme, up to its control level and in a 20% reduced rate of cytochrome P-450 inactivation. It has been shown that destroyed liver cell membranes may be repaired by the introduction of phosphatidylcholine in the form of multilayer liposomes.

Sera from 82 patients with acute or chronic hepatitis and 40 chronic carriers of hepatitis B were examined by ELISA and immunoblotting for reactivity with the glycolytic enzyme aldolase. The results of the ELISA tests, expressed as a percentage of a positive control, were compared to those obtained with sera from 39 patients with rubella, 11 with cytomegalovirus infection and 74 healthy subjects. The ELISA reaction with sera, expressed as mean +/- standard deviation was, for 15 patients with hepatitis A, 58.3 +/- 20.5%; 15 with hepatitis B, 59.5 +/- 42.18; 23 with hepatitis non-A, non-B 51.1 +/- 34.4%; 11 with HBsAg positive chronic active hepatitis, 70.1 +/- 31.5%; and 17 with autoimmune chronic active hepatitis, 66.8 +/- 21.4%. All values were significantly (p less than 0.05-p - less than 0.001) higher than those obtained with sera from carriers of hepatitis B surface antigen, 25.6 +/- 27.2%; rubella, 21.1 +/- 20.0%; cytomegalovirus infection, 19.2 +/- 27.8%; or healthy subjects, 20.9 +/- 16.2%. In two randomly selected sera, reactivity with aldolase by ELISA was neutralized by absorption with the enzyme. Selected sera showing reactivity by ELISA reacted by immunoblotting with aldolase. The findings suggest that acute or chronic liver damage may provoke the production of autoantibodies to aldolase.

Level of fructose-1-monophosphate aldolase was decreased in blood serum after administration of phosphatidyl choline-containing liposomes into male rats with experimental toxic hepatitis caused by treatment with hepatotropic poison CCl4 at a dose of 0.25 ml/100 g of body mass. The rate of the aldolase level normalization depends on composition of liposomes as well as on the pathway of their administration.

Radioimmunoassays specific for fructose-1, 6-diphosphate aldolase isozymes were developed for the quantification of human aldolase A, B and C. The method is a double-antibody radioimmunoassay using radioiodinated purified aldolase A, B and C as ligand, chicken antibodies to aldolase A, B and C, and rabbit antibodies to chicken IgG. The Iodogen method was used for the iodination of aldolase A, B and C in this study. Aldolase A was predominantly high in concentration in muscle, aldolase B was high in normal adult liver, and aldolase C was high in adult brain. Aldolase A was elevated in hepatoma tissue and hepatoma cell lines, where aldolase B was distinctly low. Normal serum levels for the three isozymes were determined. The aldolase A levels in serum obtained from 41 normal subjects were 170 +/- 39 ng/ml. Serum aldolase A levels were increased in many patients with cancer and muscle diseases, but were not increased in patients with hepatitis or other benign diseases. Serum aldolase B levels obtained from 11 normal subjects were 28.5 +/- 9.2 ng/ml. Serum aldolase B levels were increased in patients with hepatitis and correlated well with serum GPT levels. Serum aldolase C levels obtained from 12 normal subjects were 2.4 +/- 0.7 ng/ml. The determination of aldolase A, B and C by radioimmunoassay may be a valuable tool in biochemical and clinical studies of aldolase isozymes.

Simultaneous determination of aldolase fructose-1-phosphate activity in the liver and blood plasma of experimental rats gives possibility to judge of histohaematic permeability of liver barriers. The presence and advancement of the pathological process in liver is characterized by acid maltase activity. Normalization of histohaematic barrier permeability is observed after ultrasonic action of 0.2 wt/cm2 intensity on the liver area in experimentally induced immunological hepatitis.

The microbiological method was used in 168 virus hepatitis patients aged 16-55 years to study the content of unbound vitamin B12 in the blood serum over the time of the disease before administration of cyanocobalamin and in the course of its application in a dose of 100 and 200 micrograms intramuscularly every other day for 3-4 weeks. In the acute stage of the disease, the patients showed an appreciable hypercyanocobalaminemia that correlated well with the disease severity and with the magnitudes of liver function tests. Cyanocobalamin administered to the patients intramuscularly in a dose of 100 micrograms every other day exerted a more remarkable normalizing effect on the level of unbound vitamin B12, bilirubin, the thymol test, aldolase and alanine aminotransferase of the blood as compared to that produced by the drug injected in a dose of 200 micrograms.

The measurement of the plasma activities of glutamic-oxaloacetic and glutamic-pyruvic transaminases, aldolase, cholinesterase, and isocitric, lactic, and phosphogluconic dehydrogenases in random samples of blood was found to be of no value in the differential diagnosis of hepatitis, obstructive jaundice, hepatic cirrhosis, and neoplastic conditions involving the liver. Serial determinations of the enzyme activities provided useful information about the course of certain hepatic disorders, particularly acute viral hepatitis.

Hereditary fructose intolerance is an autosomal recessive disorder that is caused by a deficiency in fructose-1-phosphate aldolase (Aldolase B). Children can present with hypoglycemia, jaundice, elevated liver enzymes and hepatomegaly after intake of dietary fructose. Long-term intake of fructose in undiagnosed patients can result in hepatic failure or renal failure. We experienced a case of hereditary fructose intolerance presenting as recurrent hepatitis-like episodes. Detailed evaluation of her dietary habits revealed her avoidance of sweetened foods and fruits. Genetic analysis of ALDOB revealed that she is a homozygote for a novel frameshifting mutation c[758_759insT]+[758_759insT] (p.[val25 3fsX24]+[val253fsX24]). This report is the first of a Korean patient diagnosed with hereditary fructose intolerance using only molecular testing without undergoing intravenous fructose tolerance test or enzyme assay.
