    Notes: Abstract. We report the ultrastructural changes occurring in human platelets during eight days of storage. Extension of pseudopodia is frequently observed, but a concentration of organelles in the centre of the platelets is found only in a minor fraction (∼5bad switch yylook 1). Striking changes can be observed in both the granules and the open canalicular system. In fresh platelets, the latter often has the form of stacked membranes that have no lumen, but these membranes separate and spread with increasing storage time. However, the openings of this system on the outer surface of the platelet remain unchanged. Some of these features differ from the morphological description of platelets activated by thrombin or ADP, and suggest that the storage lesion is the result of a prolonged weak activation that leads to an incomplete release reaction within the first five days.

    Description: Trotz relativ guter physiogeographischer Rahmenbedingungen fällt die Landwirtschaft Mecklenburg-Vorpommerns nach Wertschöpfung, Flächenproduktivität, Subventionseffektivität weit hinter die der westlichen Bundesländer zurück. Ursachen sind unter anderem die Inflexibilität und Unproduktivität übergroßer Unternehmen, die Dominanz billiger Massenproduktion und der Verzicht der Großbetriebe auf die Bedienung nachfragestarker Marktsegmente im ökologischen und hochqualitativen Bereich. Die Subventionierung und Privilegierung der großbetrieblich strukturierten Agrarindustrie muss abgebaut, die Förderung innovativer kleiner und mittlerer bäuerlicher Betriebe intensiviert werden. Die Infrastruktur in Ländlichen Räumen muss wachstumsorientiert für Landwirtschaft, Tourismus, hochwertiges Wohnen und seniorenbezogene Dienstleistungen ausgebaut werden.
    Description: In spite of relatively good general conditions and good soils, agriculture in Mecklenburg-Vorpom-mern is the only economic sector in the state whose gross value added has not seen a positive development in the last 20 years. Mecklenburg-Vorpommern’s agricultural sector stagnates at a low level and with a productivity of only 613 euros per hectare at 31.7 per cent below the German average. One of the most significant causes for this are the large farming businesses which are specialised in cheap mass production. Low area productivity is a result of inadequate flexibility of the large farming companies when it comes to reacting to market signals. Whilst smaller farms, which dominate agriculture in West Germany, can adjust their productive alignment relatively quickly or diversify to mix their income, large farming businesses try to avoid changes or put them off for as long as possible. The form of production, which is dominated by industrial farming, and the marginalisation of small and medium-sized farms as a result of land speculation and price dumping, cause the federal state of Mecklenburg-Vorpommern regional economic damages of at least € 250 million annually. The subsidisation and privileged treatment of industrial farming has to be cut down on as quickly as possible. We propose a new model of cooperation in rural areas called “Garden of metropolises”. It combines small and medium sized farms, preferably family farms, with tourism, leisure, high quality service, medium and high standard of living.
