42 horses were examined. The physical signs with relation to circulatory insufficiency and the abdominal disease were registered following a two-phased examination procedure. Great prognostic value was found in the degree of circulatory insufficiency judged by pulse rate and character, filling of the jugular vein, skin temperature, colour of mucous membranes, capillary refill time, sweating, depression, skin turgor and degree of enophthalmus. In making a causal diagnosis the abdomen was examined for shape, tenderness, peristaltic sounds, gastric dilation by siphoning, abnormal rectal findings and macroscopic changes in peritoneal fluid. Greatest diagnostic difficulties were encountered in cases of intestinal atonia, acute enteritis and torsion of the colon. In selected (severe) cases laboratory tests were obtained. Blood samples were examined for packed cell volume, hemoglobin, red and white blood cell counts, differential white blood cell count, blood gases and acid-base status, lactate, serum total protein and albumin, plasma sodium, potassium, chloride, calcium, magnesium, inorganic phosphorus, glucose, creatinine, BUN, total bilirubin, ASAT, CK, BASP and GGT. Peritoneal fluid was examined for red blood and white cell counts, total protein, specific gravity, pH and lactate, and enzymes as in blood. Laboratory results generally confirmed the clinical signs of shock, and packed cell volume and blood lactate were regarded to be of greatest prognostic interest. Although the performed laboratory information, macroscopic evaluation was thought to reveal sufficient information in most cases. It was concluded that supervening shock is of decisive importance in severe forms of colic, and that a careful and repeated evaluation of the circulatory insufficiency often provides one with a tentative prognosis although the final diagnosis is not obtained. In spite of therapy fatal outcome was found in all seriously shocked horses.

In a prospective study 122 patients with a slipped lumbar disc and no previous surgery were preoperatively examined for fibrinolytic activity. Surgical results for these patients were evaluated 12 months postoperatively by clinical overall assessment. In a multiple linear regression analysis fibrinolytic variables, euglobulin clot lysis time and plasminogen activator inhibitor 1, were shown to have predictive value regarding outcome of surgery; that is, normal fibrinolytic activity favors a satisfactory outcome and vice versa. Background variables and lipid profile were also recorded preoperatively. Body mass index, gamma-glutamyl transpeptidase, triglycerides and smoking were of statistical significance in relation to euglobulin clot lysis time and plasminogen activator inhibitor 1. Postoperative fibrinolytic re-examination of 20 patients seem to confirm that patients at risk of surgical failure have a prolonged depression of fibrinolytic activity.

Dried, milled Cestrum laevigatum plant material was drenched to 6 ewes at doses ranging from 2,5 to 10 g/kg/day for 1 to 47 days. The most noticeable clinical signs were depression, anorexia and ruminal stasis. These signs were accompanied by clinical pathological changes indicative of liver involvement such as increases in the serum activities of aspartate transaminase, lactate dehydrogenase and gamma-glutamyltransferase. Hepatosis characterized by accentuated lobulation, and centrilobular to midzonal coagulative necrosis, haemorrhage and congestion occurred in 2 of the 3 ewes given high doses of plant material. Liver lesions in the other animals included disappearance of hepatocytes and collapse of the reticulin stroma in the centrilobular areas. Spongy changes in the cerebral white matter were evident in the ewes of the high-dose group. Ultrastructural changes in the liver comprised degeneration and necrosis of hepatocytes and occasionally endothelial cells, and disruption of sinusoidal walls.

Chronic alcoholics are all too often not recognized in general practice. Diagnosis is only possible if the doctor assumes potential alcoholism in all his patients. Because of the tendency of the patient and often his family to deny alcohol dependence, diagnosis is only possible by taking psychiatric, somatic and psychosocial aspects into consideration in addition to an independent history. Questionnaires may be helpful. The severity of the dependence on alcohol is not a predictor of success in therapy. In practice, three types of alcoholics may be distinguished: (1) patients with stable social relationships; (2) patients with stable social relationships and severe anxiety or depression with alcohol abuse as an inadequate self medication; (3) patients who are not able to maintain stable relationships. The latter are unlikely to be successfully treated by a family physician. A careful classification of patients according to these simple criteria may reduce the rate of treatment failures. Therapy by the family physician is initiated with an extensive somatic, psychiatric and psychosocial work-up, and maintained by counseling and care. An important factor is close collaboration between physician and social worker. Disulfiram may be a powerful adjunct to the therapy of the family physician if supervised by a trustee. In our departments we work with alcoholics in a joint consultation service involving an internist and a psychiatrist. Two thirds of the patients who consent to supervised disulfiram remain in the program for a year. 3 months after initiation of the treatment, gamma-glutamyltransferase, ASAT, ALAT and MCV are normalized. A follow-up 5 years after treatment indicated the efficacy of this treatment.

Mast cells and macrophages isolated from sensitized rats are unequivalent producer of enzymes in systems in vitro. Allergen intensifies exocytosis of acid phosphatase in them but the activity of allergen-induced enzyme secretion by macrophages ++ in immunized rats is lower than the activity of spontaneous secretion of acid phosphatase in suspensions of macrophages + in nonimmunized rats. Macrophages rather than mast cells show the ability for exocytosis of C4-gamma-glutamyltranspeptidase, leukotriene++ catabolism enzyme. Cocultivation of immune macrophages with syngeneic mast cells in the presence of allergen is followed with sharp depression of the activity of this enzyme secretion, that can create conditions for prolongation of eicosanoid effects in allergy.

Exposure to hyperoxia causes loss of alveolar macrophage cell function. Toxicity was measured as suppression of the respiratory burst stimulated by phorbol myristate acetate subsequent to exposure (43.5% depression by 2-h exposure to 5 atm absolute O2 vs. controls). The presence of extracellular glutathione significantly protected these cells (7% loss). gamma-Glutamyl transpeptidase, a membrane enzyme with its active site directed outward, was necessary for use of extracellular glutathione. This was demonstrated using the gamma-glutamyl transpeptidase inhibitor, serine-borate complex, which significantly blocked both protection of cells by extracellular glutathione and extracellular glutathione-dependent synthesis of glutathione. The principal use of glutathione in antioxidant defense is as a substrate for glutathione peroxidase. The apparent Km for glutathione of glutathione peroxidase of rat alveolar macrophages was determined to be 2 mM; however, rat alveolar macrophages have approximately 1.3 mM intracellular glutathione, which is insufficient for maximal enzymatic activity. During hyperoxic exposure, this deficit would probably be more significant. Thus the ability of extracellular glutathione along with gamma-glutamyl transpeptidase activity to provide amino acids for de novo glutathione synthesis appears to be a potentially important component of antioxidant defense.

Metadoxine is an active drug for treatment of acute and chronic alcohol intoxication, affecting both liver and brain function. The authors reviewed the international pharmacological and clinical literature on the drug which shows the potential usefulness of metadoxine in the treatment of alcohol-induced diseases. The case report concerns the results in 20 chronic alcoholics, admitted to the hospital for acute alcohol intake treated with metadoxine (one 500 mg tablet twice daily). Biohumoral hepatopathy parameters and clinical parameters of neuropsychic behaviour were examined simultaneously. Compared with a control group of patients undergoing traditional therapy (sedative and multi-vitamin drugs), metadoxine showed a significant improvement of the values of gamma-GT, GPT, blood ammonia, blood alcohol and of neuropsychic and behavioural parameters such as agitation, tremor, asterixis, sopor and depression. No side-effects or unfavourable reactions occurred during metadoxine treatment, which confirms the safety of this molecule.

Several endocrine parameters were assessed in 35 alcoholic inpatients after admission to hospital, and 17 of the 35 were retested after several weeks of sobriety. No difference was found in clonidine-stimulated growth hormone (GH) secretion between male alcoholics and male healthy controls, but significant positive correlations of GH secretion and alcohol content in expired breath on admission and gamma-GT values after abstinence were observed. Nonsuppression in the dexamethasone suppression test was found in 17% of the patients on admission, which seemed to be due to alcohol withdrawal. Postdexamethasone cortisol levels were significantly positively correlated with the "apathic syndrome" (r = 0.40; p less than or equal to 0.05). About one-third of the patients showed a blunted response in the TRH-test both on admission and after abstinence. No significant influence of alcohol intake, withdrawal or familial disposition on prolactin values could be detected. The results of the TRH test and the DST point to similar endocrinological patterns in alcoholics as in depressive patients and thus support the hypothesis of a link between alcoholism and depression.

Buffer mainly consisting of 100 g of sodium bicarbonate and 30 g of magnesium oxide was added to the feed per head per day and given for 8 months to groups of 92 cows of milk fat depression. Milk fat increased from 3.06% (pre-treatment) to 3.68% at 4 months and 3.71% at 8 months post-treatment. Solids-not-fat was slightly increased by the buffers. Milk production was not affected. The number of rumen protozoa increased from 2.85 X 10(5)/ml (pre-treatment) to 9.61 X 10(5)/ml at 8 months post-treatment and the kinds of protozoa diversified. An increase of acetate and decrease of propionate were observed together with increased milk fat at 8 months post-treatment. An increase of hematocrit, lactate dehydrogenase, sodium and potassium, and a decrease of cholesterol and gamma-glutamyl transpeptidase in blood were recognized after the treatment. The incidence of disease was reduced. There was a significant correlation between increased milk fat percentage and increase in the number and the kinds of protozoa.

Starvation for 24 h causes a striking fall in glutathione content from 3.19 +/- 0.27 to 1.88 +/- 0.14 (X +/- SEM) mumol/g tissue and of GGT activity from 31.75 +/- 4.17 to 19.49 +/- 3.13 (X +/- SEM) nmol/min/mg protein in the homogenate from whole mucosa of the upper small intestinal segments. This was associated with a significant increase in GSH-Px activity and the content of lipid peroxides (measured by the thiobarbituric assay). On semi-synthetic iron-supplemented diet the activities of GSH-T and GGT were significantly decreased as compared with crude diet. On semisynthetic iron-depleted diet GSH-T and GGT activities were further depressed, but this was accompanied with an additional depression of GSH, glutathione reductase (GSSG-R), and glutathione peroxidase (GSH-Px) activities and lipid peroxide concentrations. Food deprivation significantly lowers the mucosal GSH-content and could lead to a destabilization of this system presumably by increased oxidative stress. As compared to normal "crude" diet, semisynthetic diets and oral iron depletion have been shown to cause a depression of the intestinal GSH system. As a consequence of these effects, the resistance of the small intestinal mucosa toward exogeneous dietary toxins might be reduced.
