Alcohol, hepatitis B, and Non A Non B hepatitis were the main aetiologies of 124 patients with hepatic encephalopathy (HE) due to histologically proven liver cirrhosis. All had severe portal hypertension (PH) and usually increased inflammatory activity of the liver. In stage I (n = 27) 7.4% died, in stage II (n = 28) 14.3%, in stage III (n = 32) 50% and in stage IV (n = 37) 94.6%. Even in cirrhotics without PH, serum albumin, cholinesterase activity and prothrombin time (PT) were significantly decreased. But only in the case of PT did the magnitude of the decrease parallel the stage of HE. Hyperammonaemia and serum creatinine were increased in parallel with the stage of HE. Therefore, in liver cirrhosis a quotient derived from decreased PT and increased serum creatinine has a good prognostic value. Early diagnosis of HE is possible on the basis of writing tests and the determination of free or toxic ammonia.

A study was undertaken to identify the nutritional parameters associated with a high risk of postoperative sepsis. The nutritional status of 162 cancer patients subjected to clean or clean-contaminated elective surgery was preoperatively evaluated according to the following parameters: percentage weight loss, arm circumference, triceps skinfold, arm muscle circumference, creatinine-height index, total serum protein, serum albumin, total iron-binding capacity, cholinesterase, peripheral lymphocytes, complement C3-C4 components, and skin tests. Patients were followed postoperatively according to a precise protocol to classify them as infected or noninfected. Postoperative sepsis was present in 40 patients who had significantly different mean values for four nutritional parameters from those of 114 patients with no complications, ie, total serum protein, 6.60 vs 6.99 g/dl, p = 0.008; serum albumin, 3.39 vs 3.66 g/dl, p = 0.001; total iron-binding capacity 301.32 vs 337.17 mmg/dl, p = 0.006; and cholinesterase, 2389.77 vs 2770.10 mU/ml, p = 0.005. Moreover, the relative risk and the attributable risk for these variables were evaluated and the significance was tested by the chi 2 test. By using multiple logistic analysis it appeared that only total serum protein and total iron-binding capacity gave an independent contribution to the risk of postoperative sepsis, while serum albumin disappeared and cholinesterase became non significant when the contribution of the first two variables was accounted for. It was also possible to identify, in a small number of patients, combinations of two variables that were associated with a very high risk of postoperative sepsis.(ABSTRACT TRUNCATED AT 250 WORDS)

In recent years nutritional status gained greater attention as a surgical risk factor. This study analyzes the frequency of malnutrition in surgical patients with solid and operable tumors, the relation to the type of tumor and stage of the disease. In addition, the clinical value of the measurements carried out is discussed. The analysis was performed in 100 cancer patients (34 gastric cancer, 56 colorectal cancer, and 10 breast cancer). The nutritional assessment included individual dietary habits, ideal weight/height, triceps skinfold, arm muscle circumference, creatinine-height index, serum protein, albumin, prealbumin, cholinesterase, transferrin, total peripheral lymphocytes, and skin tests. The results were compared with international standards or normal plasma concentrations respectively. Most patients suffered from an alternation of the nutritional parameters indicating malnutrition, mostly Kwashiorkor-Marasmus Mix. Patients with gastrointestinal cancer, especially gastric cancer showed more often a decline of the nutritional status than patients with breast cancer. Malnutrition became more severe with advanced disease. The parameters examined revealed varying significance with respect to the assessment of the nutritional status. Some measurements showed little clinical importance; the reasons are discussed.

In recent years nutritional status gained greater attention as a surgical risk factor. In 100 patients with solid and operable tumours nutritional assessment with different types of measurements (dietary habits, ideal weight/height, triceps skinfold, arm muscle circumference, creatinine-height index, serum protein, albumin, prealbumin, cholinesterase, transferrin, total peripheral lymphocytes, and skin tests) was performed. Individual abnormal nutritional measurements were compared with the incidence of complications postoperatively, which were found in 32 out of 95 patients. These complications appeared more often in correlation with the decline of nutritional status. However, we could not prove a statistically significant correlation between the examined parameters themselves and the incidence or lack, respectively, of postoperative complications. Possible reasons are discussed.

Clinically normal Nubian goats were given the antiprotozoal drug imidocarb at single intramuscular doses of 6, 12, 18 and 24 mg/kg, and the various clinical, biochemical and pathological manifestations were recorded. At a dose of 6 mg/kg the drug produced no change in any of the parameters studied. At higher doses, the drug produced dose dependent changes which included increased heart and respiratory rates, increased defaecation, urination, depression, incoordination of movement, weakness of the hindlegs, recumbency, and finally death. Just prior to death, there was a significant decrease in the number of erythrocytes, and in packed cell volume, and haemoglobin concentration. In plasma there was an increase in the activity of aspartate transaminase, urea and creatinine concentrations and inhibition of cholinesterase activity. The main histopathological changes were associated with hepatic and renal damage. Three goats were pre-treated with atropine sulphate (1 mg/animal) and after one hour given imidocarb intramuscularly at a dose of 12 mg/kg. The changes were similar but much less severe when compared with those in animals given imidocarb alone at the same dose.

Eight hematologic parameter values, 16 serum biochemical constituents, serum protein fractions and albumin-globulin ratios were determined in blood samples obtained from 879 normal, healthy Beagle dogs of both sexes which had been reproduced and bred in our laboratories. The blood samples were collected from the Beagles that ranged in monthly ages from 1 to 12 and in monthly ages from 13 to 121, which were classified as the adult class. As a result, red blood cell counts, hemoglobin concentrations and packed cell volumes increased with growth. Red blood cell parameters of normal Beagles in our laboratories were rather higher than those in literatures presented by many other researchers. MCV decreased and MCHC increased gradually with age. Total serum protein concentrations increased with growth. alpha 1-1 and alpha 1-2 Globulin fractions descended, but beta 2 and gamma globulin fractions ascended in serum proteins. Alkaline phosphatase activities, inorganic phosphorus concentrations and glucose concentrations decreased conspicuously with growth. Leucine aminopeptidase activities and calcium concentrations decreased slightly. Serum cholinesterase and LDH activities showed a tendency to diminish similarly. Blood urea nitrogen and creatinine concentrations multiplied gradually. Hematologic parameters became almost steady in our 7-month-old dogs or older ones and serum biochemical constituents had a tendency to be stable in our 7- to 9-month-old dogs or older ones in the blood. White blood cell counts, alkaline phosphatase activities, inorganic phosphorus concentrations, glucose concentrations, leucine aminopeptidase activities and calcium concentrations were lowest in the adult class.

In the United States, the drugs most commonly used to treat peptic ulcer disease are antacids and the H2-receptor antagonists cimetidine and ranitidine. Other available agents include anticholinergics and the coating agent sucralfate. Investigational drugs such as colloidal bismuth, carbenoxolone, prostaglandins, the tricyclic compound pirenzepine, and substituted benzimidazoles are not available for use in the United States. Most of the commercially available and investigational compounds have similar efficacy; therefore the optimal drug may be the one associated with the fewest adverse effects and the most convenient dosing regimen. Cimetidine causes a small number of adverse effects, including neuropsychiatric disorders, gynecomastia, impotence, loss of libido, elevation of serum creatinine and serum transaminases concentrations, and drug interactions. Some of these reactions have been of clinical significance. Presently, there are rare reports of gynecomastia, bradycardia, inhibition of acetylcholinesterase, headache, lethargy, diarrhea, and rash in patients receiving ranitidine. Antacids can produce either diarrhea or constipation and have been associated with low serum phosphorus concentrations, and metabolic alkalosis. Anticholinergics, especially in elderly or debilitated patients, can cause central nervous system disorders, intestinal atony, or urinary retention. Sucralfate may cause constipation, diarrhea, nausea, and headache. The investigational agents have their own side effect profiles. The adverse effects of anticholinergics make them unattractive therapeutic choices, and antacids and sucralfate have inconvenient dosing requirements compared with some equally efficacious alternatives. In addition, clinical experience with sucralfate in the United States is limited. The safety record of cimetidine is admirable. As clinical experience with ranitidine increases, currently unrecognized adverse effects may be reported. However, based on current data, ranitidine is as effective as cimetidine and is associated with a lower incidence of side effects.

Sixty male workers in a lindane (gamma-hexachlorocyclohexane)-producing factory were examined with regard to health in comparison with an external control group of 20 clerks. Case history, physical examination, neurologic status, and ECG revealed no significant differences between groups. However, the following significant differences in clinical-chemical blood tests were ascertained: higher polymorphonuclear leukocyte count, lower lymphocyte count, higher reticulocyte count, lower prothrombin (Quick's) test, and lower blood concentrations of creatinine and uric acid. No significant differences were observed in total red and white blood cell as well as platelet counts, hemoglobin content, the other counts of differential blood picture, gamma-GT, GOT, GPT, LDH, cholinesterase, triglycerides, cholesterol, and urea. In spite of a pronounced exposure to the alpha-, beta-, and gamma-isomers of hexachlorocyclohexane, no signs of severe impairment of health were observed; only small deviations in some laboratory tests were found having no pathologic significance. However, biological monitoring and health supervision of HCH-exposed workers should be carried out.

Normal megakaryocytes take up and store serotonin (5-hydroxytryptamine) (5-HT). Murine megakaryocyte colonies were grown in plasma clot cultures, labeled autoradiographically with 3H-5-HT-creatinine sulfate, and stained for acetylcholinesterase. Silver granules representing serotonin uptake were present over almost all acetylcholinesterase-positive cells, including both mature megakaryocytes and smaller mononuclear cells. There was no evidence of serotonin accumulation in non-acetylcholinesterase staining granulocytic, monocytic, or erythroid cells. The results of this study provide: (a) a new label to identify murine megakaryocytes and smaller mononuclear megakaryocyte precursors (progeny of CFU-M) in plasma clot cultures, (b) further evidence that immature acetylcholinesterase-positive megakaryocyte precursor cells possess the ability to take up and store serotonin, and (c) evidence that this function of megakaryocytes and megakaryocyte precursors is preserved in the artificial environment of plasma clot cultures.

The involvement of the brain, lungs and kidneys was studied in a lethal rat malaria. Lewis inbred rats were infected with Plasmodium berghei K173. The disease proved fatal within 10-14 days. Parasitaemia showed an increase of up to 43% parasitised red blood cells on Day 10 p.i. The haematocrit decreased from 50% to 12%. The systolic blood pressure dropped from 99 to 56 mmHg. The lactate dehydrogenase activity rose to 2,543 U/l. BUN and serum creatinine doubled during the course of the disease. The transaminases increased tenfold and the cholinesterase decreased from 943 U/l to 271 U/l. Morphologically the kidneys showed an immune complex glomerulo-nephritis with a normal tubulo-interstitial system. The brain, heart and lungs were normal by light microscopic examination. Marked anaemia and shock were the main causes of death in the above-mentioned specimen rat, showing that the course of the disease is significantly different from lethal infections in humans with Plasmodium falciparum who show severe pulmonary, renal and cerebral complications.
