    Notes: Summary The amounts of C and N that pass through the nematode biomass in four cropping systems, barley without and with N fertilization, grass ley and lucerne, has been estimated. The nematodes were sampled at the field site of a Swedish integrated research project “Ecology of Arable Land: The Role of Organisms in Nitrogen Cycling”. The nematode biomass was lower (200 mg dry weight m−2) in the annual (barley) than in the perennial (grass and lucerne, 350 mg dry weight m−2) crops. For respiration, the nematodes used 4–71 O2m−2 year−1 corresponding to C liberation of 1.3%–2.0% of the carbon input to the soil. A higher relative contribution by bacterial-feeding nematodes to the C and N fluxes and a higher turnover rate of the nematode biomass is an indication of more rapid nutrient circulation in the annual than in the perennial cropping systems.

    Plasma amino acid response to single test meals in humans (1979)

    Notes: Summary For supplementary weaning foods, Faffa (Ethiopia), Incaparina (Guatemala), Superamin (Egypt) and Sekmama (Turkey), were studied with regard to protein quality. Three different methods for protein quality evaluation were used. 1. Chemical analysis of the essential amino acid content. Amino acid scoring of the results indicated that the sulphur-containing amino acids were limiting in Faffa (77%); lysine, threonine and isoleucine in Incaparina (77–75%); threonine in Superamin (80%) and threonine and the sulphurcontaining amino acids in Sekmama (90%). 2. Standardized nitrogen balance procedure using laboratory rats. The net protein utilization of the four weaning foods were all in the range 56–70%. Methionine supplementation (1 g/100 g protein) did not significantly improve the biological value of the test diets, but resulted in marked decreased levels of blood urea nitrogen (except for Incaparina), and decreased urinary excretion of urea nitrogen compared to total nitrogen excretion (except for Superamin). 3. Single meal plasma amino acid responses in healthy young adults. The responses of the essential amino acids after test meals with the four weaning foods were all within a range considered to indicate a well balanced supply of dietary amino acids, except for marginal deficits of methionine after the Faffa test meals, and isoleucine after the Incaparina test meals.

    Fibrinopeptide A and fibrinogenfragment B β 15–42 and their relation to the operative trauma and post-operative thromboembolism in neurosurgical patients (1987)

    Notes: Summary In an earlier study on post-operative thromboembolism in neurosurgery the incidence of deep vein thromboses (DVT) diagnosed by the fibrinogen uptake test and phlebography was reduced to the same extent by two different prophylactic methods (low dose heparin or calf muscle stimulation + dextran). However, patients with lower limb paresis due to a brain lesion experienced relatively often a less successful prophylaxis compared to patients with spinal lesions. There are few reports on successful clinical methods for haematological screening of post-operative DVT. The aim of this study was to examine possible haematological indicators for postoperative thromboembolism and secondarily to elucidate whether there exist some special coagulatory or fibrinolytic characteristics in patients who had been operated upon for brain lesions. We have studied two specific coagulatory factors (FPA reflecting thrombin generation and Bβ 15–42 reflecting plasmin activity) in connection with neurosurgical operations. Patients in the above-mentioned study on post-operative DVT operated upon for malignant cerebral tumours or intracranial vascular disease exhibited postoperatively higher values for FPA compared to other neurosurgical diagnoses. B β 15–42 was higher in the malignant tumour group and almost significantly higher in the intracranial vascular group (p〈0.065). These differences could not be ascribed to the occurrence of DVT. Another 15 patients divided into a minor and a major lesion group were investigated with determination of both parameters pre- and post-operatively. Concerning FPA an increase was noticed post-operatively compared to pre-operatively in the major lesion group. B β 15–42 was higher post-operatively in this group compared to the minor lesion group. The results indicate a hyperactivity of the coagulatory system in patients with surgically treated brain parenchyma lesions. These patients are prone to develop post-operative DVT.
