| Discrimination of Two Fusogenic Properties of Aqueous Polyethylene Glycol Solutions  | | | | Abstract
| Investigations on the dose response of cell fusion, induced by ionfree aqueous polyethylene glycol (PEG) solutions, reveal distinct lowest fusogenic PEG concentrations for different permanently growing mammalian cell lines. Part o f the requisite PEG can be replaced by carbo hydrates, preserving the fusogenity o f the solutions. This discriminates two effects o f PEG solutions causing cell fusion: a) cell shrinkage, the required hyperosmolality o f the solutions may be provided by PEG or by carbohydrates, is supposed to cause intracellular processes necessary for consolidating polycaryons; b) membrane alterations, which can not be induced by carbo hydrates, enable intimate cell-cell contact via particle-free membrane areas. Depending on cell line salts can not only raise the osmolality o f PEG solutions but are able to co-operate with PEG in generating membrane alterations. | | | |

| Effects of Vitamin A in the Presence of Vitamins D3, E, K, on Red Cell Membrane Structure | | | | Abstract
| The incubation of erythrocyte ghosts with mixtures of vitamins A + D 3, A+E, A + K , produces decrease or increase of fluorescence anisotropy r of the DPH probe, depending on the vitamin/vitamin ratio. We found a correlation between the order parameter S and cell fusion phenomena observed by phase contrast microscopy. | | | |
