SummaryLysolecithin is adsorbed to washed blood platelets and, at sufficient concentration, lyses them, inhibits their clot-retracting activity and promotes their thromboplastin-generating activity. Lysolecithin adsorption to the platelet was studied by using P32-labelled lysolecithin obtained from the liver of rats injected with labelled orthophosphate. The amount of lysolecithin adsorbed to the surface of the washed platelet in saline medium is dependent on the concentration of lysolecithin in solution and reaches saturation — 5 × 10-8 jig per platelet — at a concentration of 9—10 µg per ml. Platelet lysis in saline medium begins at a lysolecithin concentration higher than 18 jig per ml. Plasma and albumin prevent adsorption of lysolecithin to the platelet and protect the platelet from damage by lysolecithin. Albumin is able to remove previously adsorbed lysolecithin from the platelet surface. The protective action of plasma explains the lack of platelet damage in blood, the plasma lecithin of which has been converted to lysolecithin by the action of Vipera palestinae venom phosphatidase, in vitro and in vivo.

The Magnetic Field

The process of producing mono-alkyl esters of fatty acids from cottonseed and sunflower oils under the influence of the magnetic field with intensity  15-45 mT  was  investigated . It was revealed that the use of the energy of  magnetic field allows to reduce the reaction time to 10 times, the excess of used alcohol to 2 times while maintaining high yield of the desired product.

The physicochemical properties of six imported and one locally produced edible vegetable oils (soybean oil, sunflower oil, sunlit oil, hayat oil, avena oil, USA vegetable oil and Niger oil) purchased from Bahir Dar city, Ethiopia, were examined for their compositional quality. All the oil samples were characterized for specific gravity, moisture content, color, relative viscosity, refractive indices, ash content, peroxide value, saponification value, smoke point, acid value, free fatty acid value and trace metals contents using established methods. The result clearly indicates that some of the oil samples exhibited unacceptable value when compared with physicochemical parameters recommended by the Codex Alimentations Commission of FAO/WHO and the specification of Ethiopian standards. The contents of nickel (Ni), copper (Cu) and iron (Fe) in seven samples were determined using ICP-OES and their concentrations were found in the range of 1.8-20.4, 45.8-82.2 and 136.04-445.0 mg/kg, respectively.
