Figure 2From: Inflammogenic effect of well-characterized fullerenes in inhalation and intratracheal instillation studiesAnalysis of BALF in the intratracheal instillation study. (A) Total cell count. (B) Neutrophil cell count. (C) Alkaline phosphatase. Each column and bar represents the mean ± standard deviation of five rats. An asterisk indicates a statistically significant difference of P < 0.05 compared to each negative control group; double asterisk, of P < 0.01 compared to each negative control group. A high dose of fullerenes induced transient inflammatory response, and a low dose of fullerenes did not.Back to article page
