Table 1. Tissue or Organ Weight to Body Weight Ratio of Control Mice or Endotoxin-Injected Mice That Did or Did Not Receive CO^a.

organ wt/body wt x 100 (%)	control-V	endotoxin-V	endotoxin-COL	endotoxin-COM	endotoxin-COH
spleen	0.22 ± 0.02	0.33 ± 0.04 #	0.31 ± 0.03	0.31 ± 0.02	0.32 ± 0.05
kidney	0.65 ± 0.06	0.71 ± 0.07	0.68 ± 0.07	0.69 ± 0.05	0.72 ± 0.06
liver	4.51 ± 0.61	4.80 ± 0.40	4.85 ± 0.34	4.96 ± 0.30	4.29 ± 1.52
mesenteric lymph nodes	0.07 ± 0.01	0.11 ± 0.01 #	0.10 ± 0.02	0.10 ± 0.02	0.10 ± 0.03

^aValues are the mean ± SD for six mice per group.

control-V, control mice treated with vehicle; endotoxin-V, endotoxin-injected mice treated with vehicle; endotoxin-COL, endotoxin-injected mice treated with 6.5 mg/(kg bw) of CO; endotoxin-COM, endotoxin-injected mice treated with 13 mg/(kg bw) of CO; endotoxin-COH, endotoxin-injected mice treated with 26 mg/(kg bw) of CO.

#Significantly different from the control group (p < 0.05).
