    Abstract:
    Since a number of experimental evidences suggests that some lipoperoxidation products can affect leukocyte migration "in vitro", we have investigated the chemotactic and chemokinetic properties of two of these products (4-hydroxy-2,3-trans-tetradecenal and 4-hydroxy-2,3-trans-nonenal) using rat neutrophils. The cells were obtained from the pleural cavity after injection of 1.0 ml isologous serum. The granulocytes were suspended in Hanks' plus BSA 2% and the motility determined by means of a modified Boyden chamber. For evaluating the chemotactic properties, the aldehyde were added into the lower compartment, while for detecting the chemokinetic power, the compounds were placed in both the compartments. Our results show that both the chemicals (in a range between nano- and micromolar concentrations) are able to exert -at different degree- a chemotactic activity. In this connection, the more active aldehyde appeared to be the tetradecenal. On the contrary, the same compounds seem uneffective in stimulating the random migration of polymorphonuclear cells.
