a
All data given as means ± SDs. There were no significant differences among the groups for cell recovery, differential cell count, or volume of ELF (P > 0.05). Comparison testing was not applied to zero values.
b
PMN, polymorphonuclear leukocyte; Mono/macro, monocytes and macrophages; Other, other unrecognizable cells; Degen, degenerated cells.
