Twelve male duodenal ulcer in-patients received in a double-blind trial either the histamine H2-receptor antagonist cimetidine (4 X 200 mg/d p.o.) or placebo capsules. Ulcer sizes were assessed endoscopically before therapy followed by repeat endoscopy at weekly intervals. Duodenal ulcer healing was significantly more rapid in cimetidine-treated patients than in those receiving the placebo (chi2 test; P less than 0.0005). Plotting of log ulcer sizes (mm2) against time (days) resulted in regression lines the slopes of which indicated the respective half-time of ulcer healing: about 6 days on cimetidine therapy and about 20 days on placebo treatment. Gastric secretion of acid, protein, pepsin, and N-acetylneuraminic acid-containing glycoproteins was not altered by a 4-week course of daily cimetidine or placebo, nor pancreatic secretion of bicarbonate and enzymes. No statistically significant changes in laboratory findings (haemoglobin, white blood-cells, neutrophils, platelets, alkaline phosphatase, blood-urea, serum-creatinine, GOT, GPT) were associated with treatment.

We looked for variables that could serve as indexes of alcohol consumption. We tested iron, gamma-glutamyltransferase, mean erythrocyte volume, mean erythrocyte hemoglobin concentration, urea, uric acid, and alanine aminotransferase, among others, in an unselected population of men, and by principal components analysis we singled out the correlation between the two enzymes and the two hematologic values. On the other hand, calculation of the coefficients of correlation between the total amount of alcohol consumed and the 10 variables studied, together with multiple regression analysis, showed that the three variables that correlated most significantly with alcohol consumption were gamma-glutamyltransferase, mean erythrocyte volume, and the use of tobacco. Critical evaluation of the results leads us to conclude that still more discriminative biological indices msut be sought and that the use of psychosocial data is also desirable.

The following blood indices were determined in the blood of 34 pregnant sows of the Large White breed under standard feeding conditions: haemoglobin, haematocrit, leucocytes, and--in the blood serum, --total protein, glucose, urea, bilirubin, cholesterol, enzyme activity (AP, GOT, GPT, GGTP) and mineral concentrations (Ca, P--inorg., Mg, Na, K, Fe, Cu, Zn, Mn). The blood was sampled in the first and third pregnancy at an average live weight of 165.12 and 197.36 kg, at an average age of 318 and 630 days and at an about the same average length of pregnancy in the time of both samplings (59 days). In younger, still growing gilts (first pregnancy) a significantly (P less than 0.05) lower content of total protein, magnesium, iron and copper was revealed, as compared with adult sows. The content of glucose, calcium, potassium and manganese in the blood serum of the gilts was significantly (P less than 0.05) higher than in sows in their third pregnancy. The adult sows showed a significantly (P less than 0.05) lowered activity of alkaline phosphatase and gamma-glutamyl transpeptidase, as distinct from gilts.

Normal values for a number of blood components of grivet monkeys are reported. Haematological data and values for glucose, cholesterol and urea are similar to those of rhesus monkeys. Activities of alkaline phosphatase (1526 U/l), glutamine oxaloacetate transaminase (30.9 U/l), glutamine pyruvate transaminase (13.7 U/l), lactate dehydrogenase (629 U/l), alpha-hydroxybutyrate dehydrogenase (175 U/l), creatine phosphokinase (227 U/l), gamma-glutamyl transpeptidase (38.7 U/l) and sorbitol dehydrogenase (14.2 U/l), and levels of lysozyme (178 mg/dl), zinc (162 microgram/dl), copper (81.3 microgram/dl) and iron (296.5 microgram/dl) have not previously been reported for this animal. Values for serum amino acids, proteins, electrolytes, triglycerides and creatinine are compared with those of other primates.

Phytohemagglutinins from sees of Myrtus communis L., either in solution or adsorbed by glutaraldehyde-treated erythrocytes, constitute an effective system for clarification of lipemic sera. It can be used in clinical analysis to avoid the interference produced by turbidity in spectrophotometric determinations. Parameters such as glucose, bilirubin, urea, uric acid, GPT, GOT, and LDH, amongst others, can be determined without interference. The content in triglycerides of 1 ml of serum can be decreased by more than seventy per cent by treatment with 50 mg of lyophilized glutaraldehyde-treated erythrocytes saturated with Myrtus communis L. phytohemagglutinins.

Ten male rhesus monkeys, each weighing 3.5 kg, were divided into four groups of 3, 3, 2, and 2, and were fed daily with 100 g pelleted food containing 300, 30, 3, and 0 ppm cadmium, respectively. Urine samples were collected every 2 weeks and blood samples every 4 weeks. One monkey each of the 300 and 30 ppm groups was autopsied for pathological examination and tissue cadmium determination at the week 24 of the experiment; the remaining 8 animals were killed after 55 weeks. The lowest exposed group (3 ppm) did not show any specific biological response to cadmium over a period of 55 weeks. In the 30 ppm group, no significant changes were observed for up to 24 weeks, although cadmium concentration in the renal cortex and urine at 24 weeks were 300 mug/g wet weight and 18 mug/l., respectively. Plasma urea nitrogen and urine protein (quantitative determination) increased after 30 and 36 weeks. At 55 weeks of the experiment, qualitative tests were negative for low molecular weight proteinuria and glycosuria, and the results remained normal for renal and liver function tests and blood analysis, although cadmium concentrations in the renal cortex of two monkeys were 460 and 730 mug/g wet weight and those in the liver were 110 and 160 mug/g wet weight, respectively. In the highest exposure group (300 ppm), urine cadmium increased to 250 mug/l. by 11 weeks, and urine retinol-binding protein, plasma GOT, GPT, and LDH increased after 12 weeks. Proteinuria (quantitative determination), glycosuria, aminoaciduria (panaminoaciduria), and erythrocytopenia were observed after 16 weeks, when urine cadmium was 500-900 mug/l. Hypohemoglobinopathy and proteinuria (qualitative determination) were observed after 20 and 24 weeks, while cadmium concentrations in the renal cortex and the liver were 760 and 430 mug/g wet weight at 24 weeks, respectively. Slightly depressed tubular reabsorption of phosphate, increased urine beta(2)-microglobulin, increased plasma urea nitrogen, and increased plasma alpha(2)-globulin fraction (electrophoresis) were observed between 28 and 30 weeks of the experiment. Creatinine clearance and plasma cholinesterase decreased after 47 and 54 weeks, respectively. Cadmium concentrations in the renal cortex and the liver of two monkeys at 55 weeks were 350 and 580 mug/g wet weight and 410 and 630 mug/g wet weight, respectively. Pathological examinations revealed denaturation, destruction, and regeneration of the epithelial cells in renal proximal tubules, but no pathological changes in osseous tissues. Critical cadmium concentration in the renal cortex was estimated to be 380 mug/g wet weight for low molecular weight proteinuria and 470 mug/g wet weight for proteinuria, glycosuria, and aminoaciduria. Critical concentration in the liver was also estimated to be 210 mug/g wet weight. The apparent biological half-time of cadmium in monkeys at autopsied stage was calculated to be 0.66, 6.4, 5.2, and 22.4 years for the 300, 30, 3, and 0 ppm groups, respectively.

Comprehensive studies were performed in Wistar rats on the relations between the dietary protein quality and the function of the adrenocortical system. The authors determined: the increase in body mass, the urea and corticosteroid concentrations in the blood plasma, the GOT (EC 2.6.I.I.) and GPT (EC 2.6.I.2.) activities in the liver, the reactivity of the adrenocortical system in vitro, the ACTH content in the hypophyses and the content of corticosteroid-binding globulin in the blood plasma. In adrenalectomized and normal rats as well as in rats treated with corticosterone or cortisol, the authors determined the GPT, GOT, amino-acid aryl amidase (EC 3.4.I.2.) and tripeptidase (EC 3.4.I.3.) activities in the liver and the mucosa of the small intestine, and the total, alpha and beta-amylase activities in the small intestine.

Male rats weighing 180-220 g were given CdSO4, 0,4 mg/kg body weight subcutaneously once a week for 6-12 months. The animals were killed after 6, 9, 12 months and following blood serum levels were determined: total protein, albumin, globulin, GPT, GOT, Al.P. and urea. The tissue tissue samples from liver and kidneys were examined histologically (acid and alkaline phosphatase). After 9 months, the difference between values of biochemical indices in the exposed and control groups was statistically significant. It has been found that the observed biochemical indices show correlation with the extent of morphological changes in liver and kidneys. These degenerative changes became more intense in the liver than in the kidneys.

Mice ingesting a standard rodent diet supplemented with polybrominated biphenyls (PBBs) were more susceptible to chlorinated hydrocarbon solvent-induced renal and hepatic damage, as well as the lethal effects of CHCl3 and CCl4, than were mice consuming control diet. As little as 0.025 ml/kg CHCl3 caused a significant increase in serum glutamic oxaloacetic transaminase (SGOT) and blood urea nitrogen (BUN) and a significant decrease in renal cortical slices accumulation of p-aminohippurate (PAH) in PBB-pretreated but not control mice. SGOT and serum glutamic pyruvate transaminase (SGPT) were greater in PBB-pretreated mice than in control mice after 0.125 and 0.005 ml/kg CCl4, respectively. Renal cortical PAH accumulation was greatly reduced in PBB-pretreated but not control mice aftter 0.125 ml/kg CCl4. The solvent-induced decrease in PAH accumulation was also greater in PBB-pretreated mice than in control mice following administration of 1.0 ml/kg trichloroethylene (TRI) and 0.15 ml/kg 1,1,2-trichloroethane (TCE).

The rats were given subcutaneously CdSO4 in doses 0.7 mg/kg of body weight once a week during one year. After the lapse of 6, 9 and 12 months, the animals were sacrificed and their blood was used to determine the preselected biochemical indices (erythrocytes, hemoglobin, hematocrit, levels of protein, albumins, globulins GOT, GPT, AP and its isoenzymes, calcium, inorganic phosphorus, urea and creatinines). Simultaneously radiological examinations were performed on prepared and dehydrated long bones being estimated. Changes were revealed in morphological parameters of long bones with a marked demineralisation of epiphyses after 9 months of investigations. The above changes were found to correlate with those referring to biochemical indices levels, intensifying with the increase of the exposure period.
