Colchicine Inhibition of Stalk Elongation
The effect of colchicine on stalk elongation in the colonial peritrich ciliate Carchesium sp. has been investigated by growing this protozoon in colchicine-containing media. The length of the stalk in control cultures was 0-4-0-9 mm. In the presence of 2-5-125 mM colchicine, stalk elongation was inhibited, and stalk length was inversely proportional to colchicine concentration. At concentration...
متن کاملThe Mechanism of Colchicine Inhibition of Mitosis
H(3)-colchicine of high specific activity (2.5 curies per mM) was prepared in order to study the mechanism of colchicine inhibition of mitosis in cultures of human cells, strain K.B. No direct effects on the duration of the cell cycle or macromolecular synthesis were demonstrable at a concentration of colchicine which completely inhibited mitosis. The radioactive compound was bound to the cells...
متن کاملTonic inhibition of chemotaxis in human plasma.
We found exaggerated chemotaxis in plasma treated with EDTA and thought that the EDTA might itself be inhibiting a tonic inhibitor(s) of chemotaxis. Our plasma fractionations suggested that evidence should be sought for a lipid moiety carrying this activity, and on spectrometry (LC-MS-MS together with GC-MS analyses), the biologically active but not the inactive fraction contained oleic and ara...
متن کاملInhibition of Chemotaxis by Phospiionate Esters
Fresh normal serum treated with immune complexes is chemotactic for polymorphonudear leukocytes (PMN's) from a variety of species (1, 2). The factor in treated serum causing specific directional migration of PMN's has been identified as a molecular complex consisting of the fifth (C'5), sixth (C~6), and probably seventh (CtT) components of complement (2, 3). The manner by which the chemotactic ...
متن کاملInhibition of human neutrophil chemotaxis by corticosteroids.
A direct inhibitory effect of hydrocortisone on granulocyte chemotaxis has been demonstrated with an increasing inhibition between concentrations of 5 microgram to 12.5 microgram per ml. Washing the granulocytes after incubation with hydrocortisone did not reverse the inhibitory effect on chemotaxis indicating a direct cellular effect. Bacteriocidal capacity of the hydrocortisone treated cells ...
