    Notizen: The frequency of two newly defined HLA antigens, HLA CT7 and DMA, was found to be greatly increased in patients with psoriasis. These two antigens and those previously found to be associated with the disease, B13, BW16 and BW17, frequently occurred together. The disease may be primarily associated with HLA DMA, or with the HLA haplotypes CT7-B13/W16/W17-DMA.

    Notizen: [Auszug] This communication is a preliminary report of studies on two such cases (to be reported more fully at a later date). The two patients were middle-aged men in whom the diagnosis of polycythsemia was confirmed by red cell volume studies using chromium-51. The renal lesions were unilateral ...

    Notizen: Electrophoretic variation of Atlantic salmon NADP-isocitrate dehydrogenase in liver extracts of material from Ireland is interpreted in terms of two loci, IDH-A and IDH-B, coding for cytoplasmically-located isozymes. The IDH-A locus is polymorphic with qIDH-A1=0.18 and qIDH-A2=0.82. This polymorphism is of potential value for investigating the population genetics of the two races of Atlantic salmon in Ireland. An additional, monomorphic band which appears in heart extracts may be a mitochondrial enzyme coded by a third locus.

    Notizen: The enzymatic solubilization of an insoluble alfalfa protein fraction was studied in a batch reactor and in a continuous flow semi-batch membrane reactor. The “white” cytoplasmic protein fraction obtained by heat precipitation was solubilized using the proteolytic enzyme trypsin. Batch studies were carried out at pH 7.7 with a trypsin to substrate ratio of 2 x 10m-3 (by weight). At 27, 37 and 47°C the hydrolysis reaction was found to be first-order in substrate concentration. The activation energy was 23.25 kcal. At 47°C the conversion level was 97% after 4 hr. For the membrane reactor system, the effects of the variables pH, temperature, substrate concentration, and trypsin to substrate ratio were evaluated with the aid of factorial design methods. The optimum operating conditions for the membrane reactor studies were 47°C at pH 7.7 with a trypsin to substrate ratio of 4 x 10-3 at a 0.5% solids concentration level. The hydrolysis process was enhanced if the reactor was operated in a washout mode prior to the addition of enzyme suggesting that soluble low molecular weight inhibitors were washed out of the reactor with the permeate. 55% of the total amount of insoluble starting material appeared as products in the permeate after 4 hr of operation under the conditions stated above.

    Notizen: [Auszug] SUCCESS in stabilizing a pinched toroidal discharge was first achieved in the apparatus known as ZETA at the Atomic Energy Research Establishment1. The stabilization was produced by applying a toroidal magnetic field (Bz) to a gas discharge combined with a metal-walled tube. A discharge similarly ...

    Beschreibung / Inhaltsverzeichnis: Résumé Une Theilerie a pu être transmise à un jeune bovin par des nymphes d'Amblyomma cohaerens recueillies chez des buffles (Syncerus caffer) de la région de Mara au Kenya. Des macroschizontes ont été isolés dans les ganglions 12 jours après les piqûres de tiques et, par la suite, on les retrouve, mais en petit nombre, pendant trois jours. Les Macroschizontes, volumineux et renfermant de nombreux noyaux, diffèrent des autres schizontes de Theileries décrits antérieurement chez des bovins d'Afrique du Sud et d'Afrique de l'Est. Ils ressemblent aux macroschizontes deT. barnetti Brocklesby, 1965 du Buffle provenant également de la région de Mara. Des Piroplasmes qu'il est impossible de différencier deT. mutans one été trouvés dans le sang du bouvillon 61 jours après la piqûre des tiques. En utilisant un test d'immunofluorescence indirecte avec un antigène à base deT. mutans (Aitong) seule, on observe une montée significative du taux d'anticorps. Le parasite ne semble pas pathogène et peut être transmis par injection de sang périphérique à un veau préalablement splénectomisé. Bien que le parasite ait des affinités certaines à l'égard deT. barnetti et deT. mutans (Aitong) son identité exacte ne peut être précisée et d'autres essais de transmission expérimentale s'avèrent.
    Kurzfassung: Resumen Se colectaron larvas repletas, de Amblyomma cohaerens, del búfalo Africano (Syncerus caffer) en la región de Mara en Kenya. Estas como ninfas, al ser puestas en contacto con un novillo le transmitieron un parásito teilerial. Se detectaron macroesquizontes en los ganglios linfáticos regionales del animal, 12 días después del contacto con las garrapatas por tres días consecutivos con niveles bajos de parasitosis. Los macroesquizontes observados fueron de gran tamaño con numerosos núcleos, siendo morfológicamente distintos a cualquier otro esquizonte teilerial de los descritos en el Este y Oeste del continente Africano. Sin embargo, estos guardan cierto parecido con los macroesquizontes de T. barnetti, Brocklesby 1965, encontrados también en bufalo en la región de Mara, Kenya. Se detectaron piroplasmas morfológicamente indistinguibles de los de T. mutans en la sangre del novillo experimental, el día 61 después del contacto con las garrapatas. El novillo tuvo un aumento significativo en el título de anticuerpos solamente al antígeno piroplàsmico de T. mutans (Aitong), utilizando la prueba indirecta de anticuerpos fluorescentes. No hubo evidencia de la patogenicidad del parásito. La forma intraeritrocitica del parásito se pudo transmitir por pasaje directo de sangre bovina a un ternero esplenectomizado. A pesar de que el parásito mostró afinidad con T. barnetti y T. mutans (Aitong), conclusiones definitivas relacionadas con la identidad del parásito están sujetas a experimentaciones futuras.
    Notizen: Summary Amblyomma cohaerens nymphs, which had been collected as engorged larvae from African buffalo(Syncerus caffer) in the Mara region of Kenya, transmitted a theilerial parasite to a steer. Macroschizonts were detected in the regional lymph node of this steer 12 days after tick application and were subsequently detected for 3 days at low levels of parasitosis. The macroschizonts were large and had numerous nuclei, being morphologically unlike any other theilerial schizonts described previously from cattle in Eastern and Southern Africa, but they resembled the macroschizont ofT. barnetti Brocklesby 1965 from a buffalo also obtained in the Mara region. Piroplasms morphologically indistinguishable fromT. mutans were first detected in the blood of the steer on the sixty-first day after tick application. The steer showed a significant rise in antibody titre to onlyT. mutans (Aitong) piroplasm antigen, using the indirect fluorescent antibody test. There was no evidence that this parasite was pathogenic. The intraerythrocytic piroplasms proved to be blood-transmissible to a splenectomised calf. Although the parasite showed affinities toT. barnetti andT. mutans (Aitong) definite conclusions regarding its identity must await further transmission experiments.
