This study was aimed to examine whether disulfiram (DS) may exacerbate the pre-existing liver damage induced by D-galactosamine (GalN) in rats. DS, 600 mg/kg, administered by gavage for 3 days caused an increase in asparagine aminotransferase (AspAT) and alkaline phosphatase (AP) and a decrease in cholinesterase (ChE) activity in the serum and decrease in AspAT and ChE activity in the liver. DS given to rats with GAlN-induced liver injury caused significant increase in alanine aminotransferase (A1AT) and bilirubin level in serum in comparison with rats with GalN-damaged liver but without DS treatment. In summary, DS exacerbates a damage of the liver of rats. This study supported the clinical observations showing enhanced liver damage in alcoholics treated with DS.

Growing rats were fed ad libitum soy protein isolate (SPI) or its peptic (SPI-P) or tryptic digest (SPI-T) for a month and their sera were examined for cholesterol and triglyceride levels and enzyme activities such as cholinesterase, glutamate-pyruvate transaminase (GPT) and alkaline phosphatase. The rats fed SPI-P or SPI-T were inferior in growth to those fed SPI. Similarly, the serum glyceride level was lower in the SPI-P and SPI-T groups than in the SPI group. On the other hand, a significant difference was found in the serum cholesterol level between the SPI-P and SPI or SPI-T groups but not between the SPI and SPI-T groups. A similar tendency was observed for serum GPT and alkaline phosphatase activities, although there were no significant differences among dietary groups in small intestinal enzyme activities. As for the atherogenic index being a risk factor inducing atherosclerosis, the order of its value was SPI-P less than SPI less than SPI-T.

The proposed system of continuous monitoring of enzyme activities is based primarily on the electrochemical behaviour of thiol compounds, and the experimental equipment is extremely simple. The determination of cholinesterase (EC 3.1.1.8) activity is described. The normal values obtained for men (73.9, s +/- 10.3 microkat/l) and for women (71.1, s +/- 10.2 microkat/l), lie within the usual range of analogous photometric methods. Systems for determination of the activities of alkaline phosphatase (EC 3.1.3.1) and adenosylhomocysteinase (EC 3.3.1.1) are described. The activity of aspartate aminotransferase (EC 2.6.1.1) is determined by a combination of enzyme reactions, in which CoA is released from acetyl-CoA. Analogous procedures are discussed for determinations of alanine aminotransferase (EC 2.6.1.2), lactate dehydrogenase (EC 1.1.1.27), lipase (EC 3.1.1.2), and phospholipase A2 (EC 3.1.1.4) activities, and for determination of substrates, e.g., acetate and carnitine. Possible determinations of an additional 199 enzyme activities and of some of substrates are suggested. By determining electrochemically active groups other than thiols this method becomes almost universally applicable.

The aim of the study is to follow up the changes in auditory and vestibular systems, common interactions between the sensory systems and the changes in some biochemical indices after vestibular loading in drivers. Several groups of drivers of heavy freight trucks were studied, aged from 25-60 and a length of service from 5 to 30 years, according to a standard programme for otoneurological examination and application of modern otoneurological methods. The biochemical investigations were performed to 32 healthy and 19 sick drivers with vestibular disorders, prior to and post vestibular provocation. The following biochemical indices were studied: serotonin, histamine, cholinesterase activity, glucose, GOT, GPT, alkaline phosphatase, calcium, potassium, sodium, chlorides, inorganic phosphorus. The biochemical changes, associated with vestibular loading of organism were established not to be strongly manifested and coming out of the frames of the normal values, nevertheless, they are significant for a given subject and should not be neglected. The data are of importance in the vocational selection of driver-applicants, prophylaxis and treatment of those working under stress situations and extreme impacts.

Adult Ascaridia galli and Heterakis gallinae obtained from the fowl (Gallus gallus) were treated in vitro with 10(-2) to 10(-5) M parbendazole and piperazine adipate for 10-60 min at 38 degrees C. Both the compounds at 10(-2) M caused mortality of A. galli and H. gallinae after a maximum of 30 min exposure. The effect of the drugs on the homogenates of the treated worm was investigated. Parbendazole (10(-2) M) inhibited malate oxidation by 68% in A. galli and 62% in H. gallinae. Piperazine adipate (10(-2) M) inhibited malate oxidation by 78% in both parasites. In A. galli oxaloacetate reduction was inhibited by 41 and 26% by 10(-2) M parbendazole and piperazine adipate, respectively; with H. gallinae this inhibition was found to be 39 and 55%, respectively. Aldolase activity in both the parasites was also inhibited by 10(-2) M parbendazole and piperazine adipate. Both compounds caused an inhibition of acid phosphomonoesterase activity, but the activities of lactate dehydrogenase and alkaline phosphomonoesterase were not affected significantly. Parbendazole (10(-2) M) had no significant effect on the cholinesterase activity of these parasites, but piperazine adipate (10(-2) M) caused an inhibition of 96% in A. galli and 93% in H. gallinae. The possible mode of action of the drugs is discussed.

F344/N rats and B6C3F1 mice were exposed to 0, 1, 3, or 6 ppm methyl isocyanate by inhalation for 6 hr on 4 consecutive days. Deaths of rats were observed following 3 ppm exposures, and mice died after exposures to 6 ppm. Deaths appeared to be related to severe respiratory distress. Survivors in high dose groups lost weight initially, then gained weight at rates equal to controls throughout a 91-day recovery period. Lung weights increased significantly in male and female rats exposed to 3 ppm, but no persistent changes in brain, kidney, thymus, spleen, liver, or testis weights were seen in either mice or rats. Blood and serum from male and female rats were taken for clinical pathology and hematology assessments on day 7 of postexposure, the day prior to the first observed deaths of these animals. No changes or only slight changes were seen in measures of serum alanine aminotransferase, sorbitol dehydrogenase, alkaline phosphatase, or in blood and brain cholinesterase activities. However, serum creatine kinase increased with dose in both males and females. Blood urea nitrogen, creatinine, and methemoglobin were unchanged. No changes were seen in counts of red blood cells or platelets, or in red cell indices. Hemoglobin concentrations and hematocrits were slightly elevated. No changes were noted in absolute leukocyte counts, but counts of segmented neutrophils increased and lymphocytes decreased.(ABSTRACT TRUNCATED AT 250 WORDS)

1. A variety of biochemical measurements were taken periodically in captive northern bobwhite (Colinus virginianus L.), European starlings (Sturnus vulgaris L.), red-winged blackbirds (Agelaius phoeniceus L.) and common grackles (Quiscalus quiscula L.) to determine whether baseline values remain sufficiently stable throughout the year for general clinical use in the absence of concurrent control specimens. 2. Variables included whole blood hematocrit and hemoglobin, plasma lactate dehydrogenase, alpha-hydroxybutyrate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, creatine kinase, butyrylcholinesterase, alkaline phosphatase, glucose, albumin, total protein, creatinine, urea nitrogen, uric acid, cholesterol, and triglycerides, and brain acetylcholinesterase. Butyryl- and acetylcholinesterase were included because of their specific uses in toxicology. 3. Significant seasonal differences were detected for each of the variables except brain acetylcholinesterase in at least one of the species. Significant species differences were detected during at least one season for all of the variables measured. 4. All species were maintained outdoors, but only northern bobwhites came into reproductive condition and showed sex-differences in the clinical variables during their normal breeding season. 5. It was concluded that reference values for the 18 clinical variables measured could be calculated from our data for adult specimens of the species studied, and that results for one species cannot be extrapolated with certainty to any other species. 6. Estimated normal bounds for each of the 18 variables measured by commonly used clinical procedures are presented for reproductively quiescent northern bobwhites, European starlings, red-winged blackbirds, and common grackles.

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.

Using fully mechanized analytical equipment, interference by haemolysis in the determination of 26 clinical chemical parameters was determined quantitatively by adding haemolysate to serum. Haemoglobin concentrations up to 6.6 g/l caused essentially no interference in the following determinations: albumin (immuno-nephelometric), alpha-amylase, calcium, chloride, cholesterol, cholinesterase, creatinine, iron, glucose, glutamate dehydrogenase, uric acid, urea, sodium, inorganic phosphate, total protein, transferrin and triglycerides. In the presence of haemoglobin, erroneously high values were found for: lactate dehydrogenase (haemoglobin higher than 0.2 g/l), aspartate aminotransferase, potassium and acid phosphate (haemoglobin higher than 1.5 g/l), creatine kinase (haemoglobin higher than 2.5 g/l) and alanine aminotransferase (haemoglobin higher than 3.4 g/l). Erroneously low values were found for bilirubin (haemoglobin higher than 0.8 g/l), alkaline phosphatase and albumin (by electrophoresis) (haemoglobin higher than 1.5 g/l) and gamma-glutamyltransferase (haemoglobin higher than 3.0 g/l).

Oxamyl (methylN',N'-dimethyl-N-[(methylcarbamoyl)oxy]-1-thiooxam imidate; CAS 23135-22-0) was tested for oral toxicity in the rat and dog (90-day and 2-year feeding studies) and in the mouse (2-year feeding study). Teratogenic potential was evaluated in the rat and rabbit and functional reproductive capacity was studied in the rat in a one- and a three-generation reproduction study. Rats fed a diet containing oxamyl at 500 ppm showed clinical signs of cholinesterase inhibition and body weight loss within 2 days. Feeding of either 100 or 150 ppm oxamyl for 90 days produced a reduced rate of weight gain without other signs of response, and no effects were detected at 50 ppm. An oxamyl feeding period of 2 years also showed depressed body weight gains in rats fed either 100 or 150 ppm. Cholinesterase activity was depressed only during the first week of feeding and only in the 150-ppm group. All other indices of response, including the type and distribution of tumors, were similar in the test and control rats and it was concluded that the no-observed-effect level was 50 ppm (equivalent to approximately 5 mg/kg). Mice fed oxamyl at 100 ppm for 6 weeks showed signs of cholinesterase inhibition and some mortalities, so the dietary concentration was reduced to 75 ppm in the 2-year study. Body weights of mice fed oxamyl at 50 or 75 ppm were lower than controls during the first 6 months of the study. No other signs of a toxic response to oxamyl were seen in mice and a no-observed-effect level of 25 ppm (approximately 2.5 mg/kg) was assigned to this compound. No evidence of a tumorigenic response was obtained. Dogs fed oxamyl at 150 ppm for 2 years showed marginal increases in serum alkaline phosphatase activity and cholesterol concentration but no tissue pathology was seen. No evidence of cholinesterase inhibition was seen. It was concluded that the no-observed-effect level for oxamyl in the dog was 100 ppm (approximately 2.5 mg/kg). In the one- and three-generation reproduction studies, litter sizes were somewhat lower in rats fed oxamyl at 100 or 150 ppm oxamyl with normal values seen at 50 ppm. Weanling body weights were normal in rats in the 50-ppm group for three generations but were reduced in the one-generation study. Pup body weights were lower in rats in both the 100- or 150-ppm groups.(ABSTRACT TRUNCATED AT 400 WORDS)
