White rats were subjected experimentally to head injury, and also observations were made on them and on 12 patients with head injuries. It was found that injection of cholinesterase brought back to normal function the endogenous cholinesterase system, the adrenal cortex and the properdine--albumin complex system. Stabilization of these indices of homeostatic activity improved the chances of survival of the animals and patients. It was concluded that it would be desirable to administer cholinesterase more frequently in the treatment of head injury.

In 50 patients with mitral stenosis in the stage of maximal clinical improvement a correlation between the functional state of liver and the morphological changes was estblished. For this purpose the serum total bilirubin concentration was determined together with the serum total protein, albumin and globulin levels, serum alanine aminotransferase, aspartate aminotransferase, cholinesterase, leucylaminopeptidase, and alkaline phosphatase activities. The bromsulphalein test, provoked hypoprothrombinemia test, and histological examination of liver biopsy specimens were made. It was found that with increasing liver morphological lesions there is a gradual but not parallel impairment of function. The most sensitive index of hepatic functional disturbances was the test of provoked hypoprothrombinemia according to Kirchmayer and Bromowiczowa. For full assessment of the degree to which the changes in the congested liver have advanced it is necessary to perform liver function tests in combination with histological examination of the organ.

The levels of C3, cholinesterase, albumin and prothrombin were determined in 46 patients (27 males and 19 females) - 26 with cirrhosis of the liver, 9 with acute hepatitis, 6 with chronic aggressive hepatitis, 1 with chronic persistent hepatitis and 4 with fatty liver. In all patients and, particularly in those with cirrhotic liver, it was shown that the normal or pathological level of serum C 3 is related both qualitatively and quantitatively to the normal or pathological levels of cholinesterase, albumin, and prothrombin. The percentage in which the levels of these four parameters were pathological was considerably higher in the cases with hepatic coma than in the cases without hepatic coma. The determination of the range of confidence for the 4 parameters showed that, in the patients with hepatic coma, cholinesterase reacted most sensitively to liver damage (0.5 - 0.94) followed by C3 and prothrombin (0.33 - 0.81). Also in the cases without hepatic coma, cholinesterase was the most sensitive indicator (0.05 - 0.29), followed by prothrombin (0.03 - 0.24), albumin and C3 (0.00-0.16).

We measured the cholinesterase activity in morning urines from 63 insulin-dependent diabetics and 27 controls. The total esterase (TotE) activity (Ellman's method) has been divided into aliesterase (AliE), pseudocholinesterase and acetylcholinesterase by means of two inhibitors, eserine and quinidine. Diabetics were divided in 2 groups according to the urinary albumin/creatinine ratio (mg/mmol, < 2 in group 1, > 2 in group 2). The urinary cholinesterase behavior was correlated with that of a known tubular lysosomal hydrolase, N-acetyl-beta-D-glucosaminidase (NAG). Compared to normals, in addition to a significant increase in urinary NAG in diabetes (in group 2 more than in group 1), TotE and AliE were also significantly raised (+36% and 109% of the controls, in group 1 as much as in group 2).

The concentration of plasma vitronectin was determined and compared with various parameters of liver function including the blood coagulation system in patients with liver diseases. The severity of cirrhosis was graded according to Child's criteria and compared with the plasma vitronectin level. Furthermore, the distribution of vitronectin in the liver of patients with liver diseases was studied by light and electron microscopy using the indirect immunoperoxidase method. The plasma vitronectin level was low in all liver disease groups as compared with the healthy controls. The difference from the controls was significant in patients with hepatocellular carcinoma and decompensated cirrhosis. Moreover, the plasma vitronectin level was positively correlated with the levels of serum cholinesterase, albumin, plasma alpha 2 plasmin inhibitor-plasmin complex and the prothrombin time and results of the hepatoplastin test. Plasma vitronectin decreased with increasing severity of cirrhosis according to Child's criteria. These results suggest that the plasma vitronectin level is a useful parameter of hepatic synthetic function in patients with liver diseases; it may also reflect the severity of cirrhosis. Light microscopy revealed vitronectin in the area of focal necrosis and the portal tracts in the liver of patients with acute viral hepatitis, in the area of piecemeal necrosis in the liver of patients with chronic hepatitis and along the area of fiber deposition in the liver of patients with cirrhosis. Immunoelectron microscopy showed vitronectin in the rough endoplasmic reticulum of hepatocytes. Moreover, vitronectin was seen around inflammatory cells, endothelial cells, Ito cells and hepatocytes in the perisinusoidal area near focal necrosis and piecemeal necrosis and on collagen fibers.(ABSTRACT TRUNCATED AT 250 WORDS)

We investigated heparin cofactor II (HC II) levels and their relationship to other haemostatic factors in the elderly in comparison with antithrombin III (AT III). We measured plasma HC II activity levels in 166 subjects aged from 61 to 99 years using a chromogenic method. HC II levels (94.4 +/- 18.5%) in the healthy elderly subjects were significantly (p less than 0.001) lower than in 40 healthy adult controls under 60 years of age (mean age: 51.5 years; 111.6 +/- 21.2%). HC II levels in the elderly subjects decreased further with age (r = 0.308, p less than 0.001) and the extent of the decrease was more marked than that for AT III (r = 0.179, p less than 0.05). There was no significant sex difference in HC II levels in the elderly. HC II levels correlated significantly with AT III levels and with acute phase reactants including sialic acid, fibrinogen, and PAI-1. HC II levels also correlated with factor VII, plasminogen, alpha 2-plasmin inhibitor, serum lipid, pseudocholinesterase, and albumin levels. These correlations were also found for AT III except active PAI-1 and tPA-PAI-1 complexes, but the correlations with acute phase reactants were stronger for HC II than AT III. We divided 154 elderly subjects into 4 groups by their pseudocholinesterase and albumin levels to estimate the effect of nutritional status on antithrombin activity in the elderly. HC II levels were normal in the elderly subjects with a good nutritional state (103 +/- 18%), but were significantly decreased in those with malnutrition (85 +/- 15%, p less than 0.001). AT III levels also showed the same tendency. These results indicate a decrease in the reserve capacity to inhibit thrombin generation at sites of atherosclerosis in response to trigger events. The deficiency of two major antithrombin factors in the elderly may indicate a tendency to thrombosis, especially in individuals with malnutrition. When considering the clinical significance of HC II, several other parameters, including age, nutritional status, hepatic synthetic ability, and the presence or absence of acute phase reaction should also be assessed.

In a prospective study we compared the usefulness of various laboratory tests (albumin, alpha-1-proteinase inhibitor (A1PI), cholinesterase (CHE), C-reactive protein, erythrocyte sedimentation rate, hematocrit) and activity indices (CDAI, VHAI) in relation to the disease activity by endoscopic criteria. Except for hematocrit highly significant differences (p less than 0.0005) of the mean values of all test results were found for patients without or with slight mucosal lesions compared with patients with severe inflammation of the mucosa. Further analysis of the data indicates the highest test efficiency (84%), sensitivity (80%), and specificity (88.6%) for CHE. CHE showed good correlations to all other tests; the highest correlation was found between CHE and VHAI (r = -0.78). We suggest that a suppression of CHE synthesis mediated by endotoxins and cytokines rather than an increased intestinal loss explains the decreased CHE in severe Crohn's disease. It is concluded from the data that CHE is a useful test to assess the inflammatory activity of Crohn's disease.

In the present pilot study we investigated the effects of urso treatment alone in comparison to a combined treatment with urso plus colchicine in PBC. 22 patients with PBC in the histological stages 1-3 entered the study. All patients were pretreated with urso alone (10-12 mg/kg) for 12 months. Thereafter treatment was continued in a double-blind randomized fashion with urso plus placebo or urso plus colchicine (1 mg/day) for another 12 months. During the initial 12 months urso treatment liver function tests improved significantly in all patients, pruritus improved in 60% of patients. After randomization to the different treatment groups the biochemical parameters stabilized at the lower level and no significant differences could be found between urso plus placebo and urso plus colchicine treatment concerning aminotransferases, alkaline phosphatase, bilirubin, cholinesterase, albumin or cholesterol. The results of this pilot study suggest that the addition of colchicine to an initial urso treatment does not lead to further improvement of aminotransferases, alkaline phosphatase, bilirubin or clinical symptoms like pruritus.

Reference serum biochemical values were determined in blood samples from 15 male, 18 female, and 4 unsexed emus (Dromaius novaehollandiae) 1 to 48 months old. Serum biochemical values also were obtained for 19 male, 26 female, and 4 unsexed ostriches (Struthio camelus) 1 to 60 months old. Parametric (mean +/- 2 SD) and non-parametric (fifth to 95th percentile) reference ranges and linear trends as influenced by age were determined for enzyme activities and concentrations of glucose, inorganic phosphate, BUN, uric acid, creatinine, triglyceride, cholesterol, total protein, and albumin. Species differences for all analytes, except cholesterol and inorganic phosphate concentrations, were detected. Creatine kinase values in ostriches were higher than those in emus. There were no linear relationships between age and analyte values in emus, and sex did not significantly (P < 0.05) affect the values in emus. Analyte values in ostriches tended to increase with age, but cholesterol, creatine kinase, inorganic phosphate, and alkaline phosphatase concentrations decreased with age. Glucose, triglyceride, gamma-glutamyltransferase, and cholinesterase concentrations in ostriches were not linearly associated with age. Age had a greater effect on the analyte values of female ostriches than it did on male ostriches. Concentrations generally increased with age in female ostriches, except for cholesterol, cholinesterase, inorganic phosphate, and alkaline phosphatase concentrations, which decreased with age.

A 29-year-old patient suffering from stenosis of the rectum and a periproctal fistula due to a severe form of Crohn's disease was completely fed by the parenteral route for 15 months, incl. 13 months at home, via a totally implanted cannula system Implantofix, Braun Co.. The patient felt throughout the period of parenteral nutrition very well, he worked and the secretion from the fistula stopped after four weeks. After 15 months of complete parenteral nutrition and elimination of oral food intake a marked improvement of the local finding in the rectum was observed. All laboratory findings (haemogram, liver tests, urea, creatinine, transferrin, albumin, cholinesterase and pre-albumin, serum levels of sodium, potassium, chlorides, calcium and phosphates) were throughout the observation period within a normal range. The body weight of the patient increased during the 15 months by 1 kg. The described case is the first one where domiciliary parenteral nutrition was used in Czechoslovakia under ambulatory conditions.
