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%.

Changes in blood-level of cadmium, zinc, pseudocholinesterase and aldolase were studied in 44 normal subjects, 40 hypertensive patients and 40 alcoholic ones. The highest serum concentration of cadmium and pseudocholinesterase, the lowest serum and blood concentrations of zinc, the lowest serum concentrations of aldolase were found in the two groups of patients, with still lower levels in alcoholic patients than in hypertensive ones. There was a negative correlation between zinc and cadmium levels in the three groups of subjects. There was a high correlation between systolic and diastolic blood pressure value and cadmium, and negative correlation between blood pressure and zinc blood and serum levels.

The significance of changes in lymph flow for the extracellular distribution and transport of cellular enzymes and for the level of enzyme activities in plasma was investigated. Specimens of thoracic duct lymph were obtained from an extracorporal lymph shunt in anaesthetized, conscious resting and treadmill exercising dogs (6 km X h-1 for 1 h) The activity of 10 enzymes and of protein content in lymph and plasma were studied, as well as lymph flow, lymphatic transport, and the lymph-plasma ratio of these compounds. Lactate, pH, and blood gases were monitored in venous blood. Lymph flow of 0.80 ml X min-1 in anaesthetized dogs more than doubled (to 1.86 ml X min-1) when the animals were conscious and resting. In anaesthetized dogs lymph enzyme activity was higher only for enzymes of predominately hepatic origin, such as choline esterase (CHE) and alanine aminoferase (ALAT), and was lower for aspartate aminotransferase (ASAT) and aldolase (ALD). In conscious dogs, due to activation of the skeletal muscle "tissue pump", lymphatic transport of enzymes with rather high activity in skeletal muscle, and of protein, is significantly enhanced. Enzyme activities in plasma, however, did not differ between the groups. Lymph-plasma activity ratios higher than one were found for lactate dehydrogenase (LDH), malate dehydrogenase (MDH), ASAT, creatine kinase (CK), ALD, and phosphohexose isomerase (PHI). Exercise stimulated lymph flow up to 4.9 ml X min-1, and increased the lymphatic activities of those enzymes with a lymph-plasma ratio higher than unity, these enzymes increasing in the plasma due to the highly increased lymphatic transport.(ABSTRACT TRUNCATED AT 250 WORDS)

A comparison of several serum tumor markers (lactate dehydrogenase (LDH), LDH isozyme, hydroxybutylrate dehydrogenase (HBD), alkaline phosphatase (ALP), cholinesterase (Choline-E), aldolase (ALD), leucine aminopeptidase (LAP), gamma-glutamyl transpeptidase (gamma-GTP), human chorionic gonadotropin (HCG), carcinoembryonic antigen (CEA) and alpha 1-fetoprotein (AFP)) was made in patients with carcinoma or benign tumor of the ovary and healthy control subjects. The greatest positive rates were obtained with the markers HBD (76.5%) and Choline-E (73.3%) for patients with carcinoma of the ovary, respectively. However, based on false positive results, Choline-E was also greatest (50.0%) for patients with benign tumor of the ovary. The lowest false positive rates were obtained with ALD, but the positive rates for patients with stage I and II diseases were 0.0%. The most suitable single marker for patients with stage I and II diseases was HBD (62.5%), followed by LDH (41.7%). Three of 4 patients with early cancer, who had normal serum LDH levels, showed abnormal LDH isozyme patterns (elevated LDH-4 and -5). A combination of LDH activity and LDH isozyme resulted in an increase in the positive results (41.7% to 70.0%), that is, the cancer patients were positive for one of the two markers. For CEA, AFP and HCG, the positive results were 26.9%, 19.0% and 7.1%, respectively. Positive and false positive rates for ALP were 36.7% and 7.1%, but the positive rates in the early stage were lower (14.3%), compared to those for LDH and HBD. HBD and LDH activities in the ovarian malignant tissues and ascitic fluids were significantly higher than those in the benign tumor tissues and ascitic fluids, resulting in a significant elevation of serum LDH and HBD levels in the patients. Moreover, it was suggested that inhibition test of ALP by the inhibitors might be able to identify the tissue origin of ALP in the cancer patients.

The fractions of lipoproteids, lactate dehydrogenase (LDH), malate dehydrogenase (MDH) and their isoenzymes as well as the fructoso-1-phosphate aldolase (F-1-PhA) and cholinesterase (ChE) activity were studied in 220 patients with diabetes mellitus, of which 156 had diabetes mellitus combined with ischemic heart disease (IHD). It was shown that the level of atherogenic lipoproteids is augmented in all the forms of diabetes mellitus and its latent stage, their highest content being seen in the disease, aggravated by IHD. An elevated level of pre-beta-lipoproteid atherogenic fraction was more common in diabetics with IHD. An increased F-1PhA and LDH5 activity was observed in all the patients examined, whereas in severe diabetes mellitus a decrease in the ChE activity was seen. The composed table of changes in the enzyme activity and atherogenic lipoproteid levels in diabetes mellitus combined with IHD, significantly differing from those of the diabetics without IHD, can be used for early IHD diagnosing in diabetes mellitus patients.

The activity of serum enzymes, such as, creatine kinase (CK), pyruvate kinase (PK), aldolase (ALD), lactate dehydrogenase (LDH), sorbitol dehydrogenase (SbDH), malate dehydrogenase (MDH), glutamate-aspartate aminotransferase (AST), glutamate-alanine aminotransferase (ALT), myokinase (MK), glucosephosphate isomerase (GPI), alkaline phosphatase (AlkP), pseudocholinesterase (PsCHE) isocitrate dehydrogenase and gamma-glutamyltranspeptidase (gamma-GTP), was determined in 256 patients with progressing myodystrophy (PMD) (Duchenne's form in 125, Becker's form in 14, pelvicohumeral form in 36, humeroscapulofacial form in 19, ocular form in 10, other rare forms in 34, and nonidentified forms in 13 patients). In the control group (64 men, 56 women and 50 children), the activity of the enzymes was found to depend on the patients' sex and age. With regard to both parameters, i. e. the degree of the enzyme activity rise and the frequency of the pathological values the most informative were CK, then PK and ALD, and then all the other enzymes. Of all the PMD forms the enzymatic activity appeared to be the highest in patients with the pseudohypertrophic malignant form. By determining the activity of five enzymes (CK, ALD, LDH, AST and ALT) and taking into consideration the patient's age, the onset and the duration of the disease one can distinguish between sick and healthy subjects, as well as between various forms of PMD.

Activities of 14 enzymes were determined in psoas muscle, smooth muscle, diaphragm, heart, brain, liver, kidney, spleen, pancreas, salivary glands, zygomatic gland, intestinal mucosa, subcellular fractions, and plasma of the dog. In pups, plasma activity of most enzymes was high, except iditol dehydrogenase (ID), glutamate dehydrogenase (GLD), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and D-fructose-1,6-diphosphate aldolase (ALS). Alkaline phosphatase (ALP), ALS, cholinesterase (CHS), creatine kinase (CK), alpha-hydroxybutyrate dehydrogenase (HBD), lactate dehydrogenase (LD), and malate dehydrogenase (MD) decreased significantly (P less than 0.01) with increasing age, but in dogs greater than 7 months, all enzymes except CK, HBD, and ALT revealed reasonably constant plasma values. Enzymes ALT, GLD, CHS, and ID are specific for liver, CK and ALS for muscle, HBD to some degree for myocardium, and alpha-amylase for pancreas. The ALP and gamma-glutamyltransferase were located in microsomes, GLD in mitochondria, MD and AST in mitochondria and cytoplasm, and isocitric dehydrogenase, LD, and the other enzymes only in cytoplasm.
