Total serum protein, serum albumin, total urine protein excretion, and the serum activity of several enzymes--aldolase (ALS), cholinesterase (CHS), leucine aminopeptidase (LAP), isocitrate dehydrogenase (ICD), aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), alpha-hydroxybutyrate dehydrogenase (HBD), creatine kinase (CK), alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT)--were estimated in rats with nephrotic syndrome (NS) at 2, 4, 6, 8, 10, 12, 16, 20, and 30 days after a single injection of puromycin aminonucleoside (PAN). It was found that: (a) total serum protein and serum albumin diminished on day 4 and returned to control values on days 20 and 30, respectively; (b) total urine protein excretion rose on day 4, reached a peak value on day 8, and then fell substantially but still remained higher than control values on day 30; (c) ALS and CHS activities increased; (d) LAP, ICD, and AST activities showed a biphasic pattern, first increasing and then decreasing; (e) ALT, LDH, HBD, CK, and ALP activities decreased; and (f) GGT activity remained unchanged. The differences in the profiles of the enzyme activities suggest their independent regulation in experimental NS induced by PAN.

The effect of mild doses of X-rays (three fractions, each of 100 R) on energy metabolism of the brain of starved rats has been investigated. It is inferred that X-radiation may cause serious detrimental changes of enzymes involved in glucose metabolism (glucose-6-phosphate dehydrogenase and fructose diphosphate aldolase) and in peroxidation (of catalase and lipid peroxidase), and of the acetylcholine activity which is determined by the cholinesterase level. Dynamics of changes in the protein and nucleic acid content of the brain has been studied. It has been shown that the level of 4-HIAA and 3M4HMA in the brain increases after irradiation of starved and normally fed rats.

Some biochemical parameters of liver and liver microsomes were studied in albino rats following administration of cobra and viper venoms at dose of 2 mg/kg body weight. The total protein content in cobra venom treated (CVT) animals and DNA and RNA contents of liver and liver microsomes were almost unaltered in both the venom treated animals while total protein content was significantly reduced in viper venom treated (VVT) animals. Alkaline and acid phosphatases activities of whole liver showed significant increase in both the venom treated animals whereas the rise in cholinesterase activity in CVT animals was not significant. Lactic acid content was significantly higher in CVT animals compared to either VVT animals or controls. The glycolytic enzymes viz., aldolase, phosphohexose isomerase and lactate dehydrogenase measured in hepatic microsomal fraction were significantly reduced while alanine and aspartate aminotransferases and gamma-glutamyl transpeptidase activities of liver microsomes were significantly elevated in both the venom treated animals compared to controls.

A 30-day ingestion of gamma-hexachlorocyclohexane (lindane) by carp (Cyprinus carpio) induced hypoglycemia without activation of two hepatic gluconeogenesis enzymes (fructose diphosphatase, EC 4.1.2.13, and glucose-6-phosphatase, EC 3.1.3.9) and hyponatremia and variations in muscle plasmic membrane-bound enzymes (especially cholinesterases, EC 3.1.1.7). After 109 days carps exhibited a decrease in natremia but no significant hypoglycemia. There was an activation of gluconeogenesis enzymes. Important changes were observed in the activities of muscle plasmic membrane enzymes (especially 5'-nucleotidase, EC 3.1.3.5, and ATPases, EC 3.6.1.3). Lindane, a lipophilic substance, especially disturbed the activity of membrane-bound enzymes enclosed in a phospholipid matrix.

The stability and storage characteristics were studied of 11 bovine enzymes of potential clinical significance, namely, aldolase, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, acetylcholinesterase, creatine kinase, gamma glutamyltransferase, glutathione peroxidase (GSH-Px), alpha-hydroxybutyrate dehydrogenase, lactate dehydrogenase and superoxide dismutase (SOD). Enzyme activities in fresh serum were compared with those in plasma containing various anticoagulants including lithium heparin, EDTA and oxalate/fluoride. The same preservatives were assessed for their effects on the whole blood activities of GSH-Px and SOD. Stabilities of enzymes in plasma and serum stored at room (+20 degrees C), refrigerator (4 degrees C) or deep freeze (-20 degrees C) temperatures were also compared. In addition, SOD and GSH-Px activities in samples stored, at the same temperatures, as whole blood or aqueous lysates were monitored.

In addition, SOD and GSH-Px activities in samples stored, at the same temperatures, as whole blood or aqueous lysates were monitored. The results are discussed with particular reference to the differences between sheep and cattle.

The enzymic tests and radionuclide hepatography were used to study and compare liver function after rabbits were exposed to tetrachloromethane poisoning. The activity of serum enzymes of cholinesterase, alkaline phosphatase, aldolase and leucine aminopeptidase was determined. Hepatography was made with the use of 198Au-colloid with an activity 0.74 MBC. The enzymic tests were demonstrated to be more sensitive than radionuclide hepatography in detecting the earliest parenchymatous lesions in the liver. The data obtained correlate with the data of the pathohistological examinations, which demonstrated the presence of marked vacuole parenchymatous fatty dystrophy. The authors recommend that the enzymic tests should be used for detecting early hepatic lesions induced by tetrachloromethane.

Studied was the enzyme constellation, resp., activity of alkaline phosphatase (AP), glutamate-oxaloacetic transaminase (GOT), glutamate-pyruvate transaminase (GPT), aldolase (ALD), leucin-aminopeptidase (LAP), cholinesterase (CE), creatine phosphokinase (CPK), lactate dehydrogenase (LDH), ornithine carbamoyltransferase (OCT), and guanase (G) in a total of 360 clinically normal and lactating and dry cows of the Black-and-White and Simmental crossbreeds. Characteristic quantitative changes were found with GOT, GPT, ALD, LDH, and CPK both over the dry period and over the entire period of lactation. The activity of LAP, AP, OCT, and G was not influenced by the functional status of the animals. In the course of the analyses there were changes in the serum ALD, CE, and GOT, associated with the breed. The enzymes referred to were studied with a view to establishing their normal parameters needed for the practice as the base to demonstrate preclinical disturbances in individual organs and tissues of the cows during pregnancy and the puerperium.

In order to identify and to characterize the antigens from Nippostrongylus brasiliensis which are involved in the in vitro blastogenesis of T cells from infected animals, we have established by crossed immunoelectrophoresis a two dimensional antigenic map of the adult worm homogenate. Polyclonal precipitating rabbit antiserum recognized 26 antigens including five enzymes in these homogenates. The antigenic enzymes, the precipitates of which are only stained by specific staining, are: aldolase, malic enzyme, acid phosphatase, peroxydase and cholinesterase. This antigenic map enable us to identify 26 antigens in adult worm homogenates and to compare them with those which will be contained in purification fractions from these homogenates or in homogenates from other parasites.

A comparison of preoperative serum tumor markers (lactate dehydrogenase, lactate dehydrogenase isoenzymes, alpha-hydroxybutyrate dehydrogenase, alkaline phosphatase, aldolase, leucine aminopeptidase, cholinesterase, erythrocyte sedimentation reaction, carcinoembryonic antigen, alpha-fetoprotein, and beta 2-microglobulin) was made in 76 patients with ovarian or uterine cancer. Sixty-six patients with benign ovarian tumor served as control subjects. From analysis of each tumor marker the greatest positive results were obtained with the markers beta 2-microglobulin (57.1%), lactate dehydrogenase (53.1%), and hydroxybutyrate dehydrogenase (46.2%) for patients with carcinoma of the ovary. The use of these marker combinations in all ovarian cancer patients resulted in a marked increase of the positive rate from 57.1 to 85.2%. In stage I cases, the positive rate increased from 40.6 to 63.6%.
