Table 1. Morphometric parameters in the respiratory mechanics of asthmatic and non-asthmatic Swiss mice after treatment with the nitric oxide metallo-donor FOR811A.

Experimental groups	Normal Alveoli (%)	Alveolar Collapse (%)	Mean Alveolar Diameter (μm)	Bronchoconstriction index (BCI)
Ctl+Sal	90.03±2.36	9.97±2.36	44.56±3.31	2.05±0.21
Ast+Sal	71.58±6.22*	28.42±6.22*	35.54±5.56*	1.99±0.17
Ctl+FOR	94.25±2.26	5.75±2.26	46.11±7.12	2.84±0.39
Ast+FOR	83.31±4.98	16.69±4.98	41.20±5.88	2.33±0.23

Values are mean ± SD of the following groups: control treated with saline solution (Ctl+Sal), asthmatic treated with saline solution (Ast+Sal), control treated with FOR811A (Ctl+FOR) and asthmatic treated with FOR811A (Ast+FOR). Data was collected in 10 matched fields per mouse. Values significantly different (p<0.05) by one-way ANOVA followed by Student–Newman–Keuls test compared to the Ctl+Sal group (*), and no difference compared to Ctl+Sal group.
