[Formation of "Rosettes" induced by polyethylene glycol]. 1976

B Fauconnier, and O Vannier

Human blood cells were washed and treated by PEG 6 000 (40% solution in BME) at 37 degrees for 15 min. A strong agglutination was observed. After dilution with 3 vol. of BME and shaking, microscopic examination at low magnification revealed small aggregates disseminated in dispersed population of erythrocytes. These aggregates were shown to be formed by a polymorphonuclear cell closely surrounded by erythrocytes. The possible explanation of the formation of such "Rosettes" was briefly discussed.

UI MeSH Term Description Entries
D007104 Immune Adherence Reaction A method for the detection of very small quantities of antibody in which the antigen-antibody-complement complex adheres to indicator cells, usually primate erythrocytes or nonprimate blood platelets. The reaction is dependent on the number of bound C3 molecules on the C3b receptor sites of the indicator cell.

D011092 Polyethylene Glycols Polymers of ETHYLENE OXIDE and water, and their ethers. They vary in consistency from liquid to solid depending on the molecular weight indicated by a number following the name. They are used as SURFACTANTS, dispersing agents, solvents, ointment and suppository bases, vehicles, and tablet excipients. Some specific groups are NONOXYNOLS, OCTOXYNOLS, and POLOXAMERS.
