The well-known French-language writer, Assia Djebar, teaches the reader to listen intently to cultural differences, inspires tolerance towards other people and touches upon the problem of the emancipation of women in the Arab-Muslim civilization. In her work entitled Le Blanc de l’Algérie Djebar recalls deceased Algerian intellectuals, such as Albert Camus, Frantz Fanon or Kateb Yacine, as well as cruelly murdered writers and less known persons, who proved to be important for the author herself (namely her friends) and for the history of Algeria. The author bemoans those absent figures, remembering their last minutes of life, their families’ despair, and the atrocity of death. The article is an attempt at a reflection on the problem of absence that is in dichotomy with presence. The absence of great Algerians is unbearable; it is not silence but a cry for the memory of the tragic moments in the history of the country. Those moments, when remembered, shall help understand better the painful contemporary times. Djebar in a subtle way removes a white shroud (white is the colour of mourning in the tradition of North-African countries), thus showing the reader the moving and colourful Algerian fresco.

A primary effort in the understanding of the progression of atherosclerotic disease has been methods development for visualization of the atherosclerotic plaque. We introduce a new method for the qualitative analysis of lipids in atherosclerotic fatty streaks which also retains those lipids for biochemical evaluation. An original aspect of the process is the ability to view an entire fatty streak en face, selectively stained for specific lipid classes within the lesion.New Zealand white rabbits were fed a high cholesterol diet(0.15%-0.3% for 14 wks). The aorta was removed and fixed in Carson's phosphate buffered formaldehyde followed by dual staining in the fluorescent dyes Nile red and filipin. Stock solutions of nile red(0.5mg/ml acetone) and filipin(2.5mg/ml dimethyl formamide) were prepared and kept at -20°C; all subsequent steps were at RT. 0.5cm × 1.0cm pieces of aorta were trimmed and adventitia removed. The pieces were then washed 3×15 min in PBS w/o CaMg, soaked in Nile red(NR)/filipin(Fl) stain(100(il NR stock + 200μl Fl stock in 10 ml PBS for 30 min, washed in PBS 3×30 min, rinsed with distilled water, mounted(Crystal Mount, Biomedia) and coverslipped and viewed by fluorescence microscopy.

Microscope slides were homogeneously coated over a length of 2 cm with a mixture of soluble and fibrillar collagen and exposed at 37°C and under laminar flow to citrated whole rabbit blood at a flow-rate of 100 ml/min. Surface coverage with platelets (adhesion) and platelet accumulations higher than about 5 μm in height (aggregation) were determined by automated microdensitometry of fuchsine stained ‘en face’ preparations. The platelet mass per unit surface was measured with a modified Lowry technique whose sensitivity was equivalent to 5×l05platelets. Platelet number, amount of protein and surface coverage with platelet accumulations correlated. After a perfusion time of 10 min thrombi up to 30 μm in height and oriented in the direction of flow had developed on the collagen coated area. Surface coverage with platelets was 75% and the amount of deposited protein 1.4 μg/mm2(2×l06platelets/mm2). On the uncoated surface single platelets predominated; the surface coverage was 20% and the density of platelets 8×104/mm2. Acetyl- salicylic acid at 100 μm decreased platelet aggregation by about 80% without affecting adhesion.The new parallel plate perfusion system offers rapid quantitation of platelet-surface and platelet-platelet interaction after exposure to flowing blood and iftay also be diagnostically useful.

A kardiológiai betegek ellátásában a noninvazív vizsgáló módszereknek alapvető jelentőségük van. Elméletileg a szív akkor vizsgálható tökéletesen, ha természetének megfelelően három dimenzióban rögzítjük a szívciklus szerint. A második generációs, immár real-time (vagyis valós idejű) háromdimenziós echokardiográfok elméletileg optimális lehetőséget nyújtanak a cardialis struktúrák háromdimenziós elemzésére. Real-time 3-dimenziós echokardiográfia során pontosan mérhetők a kamrai és pitvari térfogatok, valamint a kamrai izomtömeg. A billentyűk és a congenitalis abnormalitások ‘en-face’ vizsgálhatók. Használhatóságát terheléses protokollok alkalmazása mellett igazolták. A jelen összefoglaló közlemény célja a módszer bemutatása, lehetséges előnyeinek tisztázása a jelenleg még fennálló technológiai korlátok bemutatásával együtt.
