Differential white blood cell counts in the peripheral blood of untreated, unoperated mice (baseline), sham-operated mice and cryoinjured mice intravenously injected with PBS, PBS liposomes, and CL₂MDP liposomes. A: In the Cl₂MDP liposome-treated mice, monocyte levels were significantly reduced on days 4 and 7 after cryoinjury compared with PBS and PBS liposome-injected mice. Levels of neutrophils (B) and lymphocytes (C) were similar in mice intravenously injected with PBS, PBS liposomes, and CL₂MDP liposomes at all time points. Significant differences are indicated as *P < 0.05, **P < 0.01. Bars represent mean ± SEM.
