The inhibitory effects of whole and fractionated acetone extracts of leaves of four species of Tanacetum were assessed in vitro, using a human polymorphonuclear leucocyte-based bioassay. Biochemical investigation detected the bioactive germacranolide, parthenolide, at high concentrations, in extract

In cells which display plasma membrane-mediated motile activities (locomotion, pseudopodia formation, chemotaxis, phagocytosis, etc.) a variety of intrinsic plasma membrane constituents, some of which contribute to the cell's electrokinetic properties, have been indicted as participants in the motil
Exudate leucocytes lost approximately 30% of their original intracellular ascorbic acid content during two hour incubation in glucose medium. The same loss was observed for cells containing initially both high and low levels of ascorbic acid. High concentrations of ascorbic acid i n the incubation m
An examination of the literature on cell permeability to water reveals the fact that very few types of cells possess characteristics which make them available for accurate quantitative determinations of permeability. The egg cells of a number of species of Echinoderms (k200 = 0.110 p3 H,O) (Luck6 an
## Abstract Polystyrene latex spherules are rapidly phagocytized by polymorphonuclear leucocytes. Surface modifications of the latex spherules can lead to an inhibition of phagocytosis, and the purpose of this study was to analyse in particular inhibition by bovine and human serum albumin. It can b
