ABSTRACT: The influence of initial placement of molecular or
ion substance is investigated on the diffusion fluxes across the cell membrane.
The diffusion fluxes and recovery curves are obtained by considering both the
singlespot and double-spot concentrations inside the cell membrane. The
results show that the additional concentration inside the membrane reduces the
net fluxes at the cell interior as well as the exterior. In addition, it is
found that the change in diffusion flux at the two outer walls of the membrane
by the two-spot concentrations in the cell membrane is weaker than that of the
single-spot concentration at the center. The variation of the influence of
initial locations of the molecular concentrations inside the cell membrane on
the diffusion fluxes is also discussed. This result can be applied to the
diffusion process in avascular collagenous tissues.
