Table 1. Concentrations (µmol/L) of the L-ornithine derived polyamines putrescine, spermidine and spermine in lung homogenates of naïve control and Pseudomonas infected mice treated with PBS or arginase inhibitor ABH.

	Putrescine	Spermidine	Spermine
Control	4.9±1.2 ^*	4.0±1.2 ^*	2.6±0.7 ^*
Pseudomonas
PBS	34.2±2.4	39.6±2.3	13.6±0.8
ABH	28.7±2.9	37.5±3.7	12.5±0.8

* Concentrations were significantly different between groups (p<0.001, ANOVA). All three polyamines were lower in controls compared to infected animals but not different between PBS or ABH treatment group (n = 6–8/group).
