(1) Numerous 70-mmicro diameter vesicles apparently pinch off from the Golgi systems, transport this material through the egg, and probably then fuse to form a crenate, membrane-limited yolk droplet.
(2) In vitro incubation of human blood cells with iodinated radiographic contrast media (RCM) produced marked effects which were dose-dependent: erythrocytes showed crenation which was reversible; neutrophil leukocytes released the lysosomal enzyme beta-glucuronidase; basophil leukocytes released histamine; and platelets released serotonin as well as beta-glucuronidase.
(3) Our results indicate: 1) linear RBC pressure-flow behavior over a driving pressure range of 2 to 10.5 cm H2O with zero velocity intercepts at delta P = 0, thus suggesting the Poiseuille-like nature of the flow; 2) resistance to flow or "apparent viscosities" for normal RBC which are between 3.1 to 3.9 cPoise and are independent of driving pressure and pore geometry; 3) increased flow resistance (i.e., increased transit times) for old versus young RBC and for RBC made less deformable by DNP-induced crenation or by heat treatment at 48 degrees C; 4) increased mean transit time and poorer reproducibility when using EDTA rather than heparin as the anticoagulant agent.
(4) The incubation of old RBCs with PEP not only increased ATP and 2,3-DPG levels, but also facilitated the transformation of crenated erythrocytes to discocytes.
(5) Isolated human erythrocyte membranes crenate when suspended in isotonic medium, but can use MgATP to reduce their net positive curvature, yielding smooth discs and cup forms that eventually undergo endocytosis.
(6) At the same time the red cells became crenated and developed thorny spicules (echinocytes).
(7) Scanning electron microscopy of the platelets revealed a gradual morphologic change from biconcave flat discs to irregular, crenated forms.
(8) This crenated cell shape was reversed to a biconcave disc or cup-like form by a further treatment with lysophospholipase.
(9) On the other hand, the process was facilitated when red cells were exposed to crenators like the anionic drugs indomethacin and phenylbutazone or when DMPC was added to calcium-loaded red cells.
(10) The abnormal erythrocyte shape (crenation) was strikingly observed in all groups after four weeks of egg yolk feeding with good correlation to lipid levels (r = 0.9, p less than 0.001).
(11) Maintaining a higher level of albumin during EC by adding 50 g human albumin to the extracorporeal system prevented erythrocyte crenation.
(12) Uptake of phosphine by erythrocytes causes crenation, but conversion of oxyhaemoglobin to methaemoglobin and hemichrome could not be demonstrated.
(13) These results revealed that ioxaglate, an ionic contrast medium, was the best in vitro medium, to prevent aggregation of red cells and crenation deformity of erythrocytes.
(14) In contrast to the control and the regression rats, many of the hypertrophic vessels of all types in the hypoxic rats showed signs of constriction, ie, crenation of the wall, indentations of medial smooth muscle cell nuclei, and excrescences of smooth muscle cell cytoplasm, often protruding deeply into the endothelium.
(15) We demonstrate that the damage consists of lifting, crenation and detachment of endothelial cells, partially due to contracture and forceful redilation of the vessel wall.
(16) KB-2796 and FNZ at 10-100 microM dose-dependently prevented crenation of rabbit erythrocytes induced by the Ca2+ ionophore A23187.
(17) Electron microscopy of the endothelial layer of intimal explants showed dilatations in the intercellular junctions and cellular changes representing contraction--increased prominence of cytoplasmic filaments, nuclear crenation, and cytoplasmic protrusions--at 30 and 60 minutes.
(18) Raising this concentration reversibly decreased the degree of crenation.
(19) These amphiphiles immediately induced strongly crenated erythrocytes which during incubation shifted to less crenated erythrocytes or to stomatocytes.
(20) Osmiophilic granules with a homogeneous core, crenated membrane and narrow submembranous halo predominated in the columnar juxtacortical cells.
