Figure 5. Effect of liposomes, carboxylate modified latex beads, or maleic vinyl ether on phagocytosis in liver macrophages. Rats were injected with (a) liposomes (PBS or Clodronate), (b) CML beads, or (c) MVE prior to injection of the Bioparticles®. Livers were removed and imaged. No Bioparticles® control represent the background fluorescence of livers with saline or test agent only. Fold-increases in fluorescence from (a) PBS liposomes or (b, c) saline controls ± standard deviation are shown. Radiant efficiencies for individual animals were corrected for their liver weights. *p < 0.001 versus Saline + Bioparticles®, p < 0.01 versus PBS liposomes + Bioparticles®; **p < 0.05 versus Saline + Bioparticles®; ***p < 0.01 versus Saline + Bioparticles®; †p < 0.001 MVE versus Saline + Bioparticles®; vp < 0.000 05 versus Saline + Bioparticles®.

Rats were injected with (a) liposomes (PBS or Clodronate), (b) CML beads, or (c) MVE prior to injection of the Bioparticles®. Spleens were removed and imaged. ‘No Bioparticle®’ controls represent background fluorescence of spleens with saline or test agent only. Fold-increases in fluorescence from (a) PBS liposomes or (b, c) saline controls ± standard deviation are shown.
