Abstract: | The permeability of the membrane of human granulocytes to the permeating solute dimethyl sulfoxide (DMSO) was studied using the Onsager form of the phenomenological equations derived from the theory of irreversible thermodynamics. Changes in cellular volume were monitored with an electronic particle counter as samples of that population were introduced into hypertonic osmotica. Temperature and concentration sensitivity analyses of the permeability coefficients were carried out. It is shown that the introduction of the Onsager formalism allows further insight into the observed transport phenomena. It was found that DMSO may affect the water permeability properties of the membrane for that population of cells. |
