    Notes: A case of recombination between the putative class I ELA antigen series and the strudure(s) governing mixed lymphocyte reactivity in an informative horse family is described. The results of serological typing, ‘lysostripping’ and mixed lymphocyte culture tests strongly suggest that the recombination took place between two loci and is not intragenic. An alloantigenic membrane structure, provisionally called B1, which does not belong to the known ELA series, was also involved in the cross-over. The B1 antigen resembles the class II gene products of other species in two respects: it is not present on platelets, and doantiserum with specificity for B1 inhibits the stimulatory effect of B1-carrying cells in mixed lymphocyte cultures. The B1 antigen does not follow the classical distribution, however, being expressed on both B and T lymphocytes. The finding of separate loci for the first series of ELA antigens and the MLR governing structure(s) demonstrates the similarity of the genetic organization of the horse MHC to that in other species.

    Notes: A randomised, double-blind investigation was undertaken into the value of metoclopramide and domperidone as anti-emetics in orthopaedic patients who received spinal anaesthesia. Seventy-seven patients were divided into three statistically comparable groups: Group I received 10 mg metoclopramide, Group II 10 mg domperidone, and Group III NaCl as placebo. These substances were given intravenously before the spinal puncture. There was a comparable decrease in mean arterial blood pressure (MAP), level of sensory block and dose of tetracaine in all three groups. The patients who were nauseated and/or vomited showed a greater decrease in MA P. The incidence of nausea and/or vomiting in the metoclopramide and the placebo group were similar, 20% and 15% respectively, whereas this complication was apparent in 35% of patients who received domperidone. We conclude that metoclopramide and domperidone in the dosages used are ineffective in alleviating nausea and vomiting after spinal anaesthesia.

    Notes: In a collaborative study by 12 laboratories the reproducibility of bioassay techniques was analysed by comparison and statistical treatment of the ED50-values (μg herbicide/g soil). Commonlyused bioassay techniques were investigated; two direct seeding methods, a transplanting method and a shoot extension method. The herbicides studied were two photosynthesis inhibitors, atrazine and metribuzin using Lepidium sativum and Brassica rapa as test plants; two germination inhibitors, tri-allate and trifluralin using Avena sativa as test plant. The mean ED50-value of atrazine in the direct seeding method was 0.18 with a variation from 0.12 to 0.29 and 0.12 (0.07–0.68) in the transplanting method. The values of metribuzin were 0.05 (0.02–0.11) and 0.03 (0.01–0.15) respectively. The values for triallate were 1.15 (0.50–2.60) in the direct seeding method and 1.10 (0.54–2.53) in the shoot extension method and for trifluralin 3.11 (0.72–18.31) and 1.33 (0.48–2.94) respectively. The reproducibility was best in the shoot extension method. No outliers (confidence intervals lying entirely outside the confidence interval of the overall mean) in the ED50-values were observed with atrazine and metribuzin when using the direct seeding method, whereas with the germination inhibitors a high number of results (four with tri-allate, six with trifluralin) could be considered as outliers. A comparison of the use of fresh weight and dry matter showed good agreement between the ED50-values they gave, with similar reproducibility.

    EQUINE LEUCOCYTE ANTIGEN SYSTEM: III. NON-MHC LINKED ALLOANTIGENIC SYSTEM IN HORSES (1982)

    Notes: A new, non-MHC linked alloantigenic membrane antigen on the equine lymphocytes is described. This antigen was characterized with alloantisera in the two-stage microcytotoxicity test and designated as ELy-1 antigen.The frequency of ELy-1 antigen positive animals in various populations is close to 50%. ELy-1 shows an autosomal, dominant inheritance. Since an allelic antigen (s) could not be demonstrated in family studies, it is assumed that only two alleles ELy-I+ and ELy-I- exist. The ELy-1 antigen in positive animals is expressed on both T and B lymphocytes but it is not present on erythrocytes and thrombocytes.The incidence of ELy-1 antigen positive animals is significantly higher in horse groups suffering from chronic bronchitis or from laminitis, compared to clinically healthy controls.

    Notes: Summary A rapid assay for soil urease in the absence of bacteriostatic agents has been developed. The method comprises incubation of soil with an aqueous or buffered urea solution, extraction of ammonium with 1 N KCl and 0.01 NHCl and colorimetric NH4 + determination by a modified indophenol reaction. The method is characterized by high sensitivity and stability of the coloured complex formed. Measurements obtained by this method showed that no change in urease activity occurred when field-moist samples of soils were stored at −20°C for as long as 5 months. Air-drying of field-moist soil samples may lead to an increase in urease activity.

    High doses of antigen-nonspecific IgG do not inhibit pemphigus acantholysis in skin organ cultures (1985)

    Notes: Summary A patient suffering from severe pemphigus vulgaris was treated using large-volume plasma exchange in combination with an immunosuppressive regimen. As some recent reports have shown evidence that polyclonal, polyspecific human IgG in high doses through the i.v. route (IGIV) protect target platelets in idiopathic thrombocytopenic purpura from attack by antiplatelet autoantibodies and/or immune complexes, we also administered IGIV to this pemphigus-vulgaris patient. In order to test the hypothesis that IGIV might protect in vitro-cultured human skin from acantholysis induced by pemphigus antibodies, studies with skin organ cultures were carried out using plasma from another pemphigus-vulgaris patient who had undergone plasma exchange. The preincubation of either the skin explants or the pemphigus plasma with various concentrations of IGIV (ranging from 0.15 to 15 mg/ml in the culture medium) did not prevent acantholysis induced by the pemphigus plasma nor did it inhibit the binding of the specific antibodies visualized by direct immuno-fluorescence. Thus, the assumption that IGIV may coat the pemphigus antigens on epidermal cells making them inaccessible to pathogenic autoantibodies was not substantiated by our tests in vitro; likewise, the hypothesis of functionally blocking autoantibody activity by means of anti-idiotype effects of IGIV cannot be supported.

    Notes: Abstract Physiologically acceptable methods for estimating milk intake in experimental animals are based on the measurement of rates of disappearance of3H2O from their body-water. This work discusses the problems involved in using methods of this type when steady-states (constant tracee inflow and outflow rates, and constant pool-size) do not exist. Theoretically sound techniques are developed and their use justified.

    The effect of propranolol on whole-body microvibrations during examination stress (1986)

    Notes: Summary Whole-body microvibrations (MV) in three dimensions were measured in 51 volunteers, all medical students, 26 without and 25 with beta-receptor blockade (propranolol), immediately before a practical physiology examination and during the ensuing vacation. Propranolol impeded the increase in MV values in all three axes, significantly those in the z axis (vertical), the differences in MV values between the two measurements being minimal in the beta-receptor blocked group. On the other hand, propranolol enhanced MV in the x axis (anteroposterior) and the y axis (transverse), the y axis difference being significant only in females. Propranolol obviously relieves examination stress: the majority of candidates (52%) felt “quieter≓ in the examination with than in other similar situations without beta-receptor blockade. Propranolol was, however, without effect on the examination results. The rectified impulse in the z axis when related to body weight (Jz) correlates linearly with the calculated cardiac output. Propranolol, however, reduced cardiac output more than Jz, pointing to a Jz component non-sensitive to beta-receptor blockade. The part played by muscle tonus, mainly reflected in the y axis, thus remains unknown. The large and slow oscillations in the x and y axes, observed particularly in beta-receptor blocked females, might be attributed to diminution in standing ability.

    Respiratory and circulatory influence on photopapillometry (1986)

    Notes: Abstract Respiratory and circulatory conditions that could have an influence on measurements of pallor of the papilla were evaluated with our photopapillometer in a controlled study on canines. The brightness of the papilla rim and the width of the arterioles emerging from the optic nerve head were measured in six anesthetized dogs under normal, hypertensive, and hypotensive circulatory conditions, as well as under various respiratory manipulations, and the parameters were compared for statistical correlation. Both brightness and vessel width remained constant for a wide range of arterial pressures when the rest of the experimental conditions were kept stable at naturally occurring levels. If respiration and circulation were brought to extreme levels, however, there was a statistical tendency for the brightness of the papilla to be dependent on arterial and pulmonary arterial blood pressure. The importance of these findings is discussed with regard to their influence on objective measurements of fundus brightness.
