Biochemical parameters measured in plasma of mice treated with saline (Control, Ctr) or formoterol (Form)

	Ctr	Form
ALT activity, nmoL/min/mL	6.3 ± 0.3	8.6 ± 0.5**
AST activity, nmoL/min/mL	22.6 ± 3.9	44.9 ± 6.1*
Insulin, ng/mL	1.2 ± 0.2	0.6 ± 0.1*
Nonesterified fatty acids, µmoL/L	439.5 ± 40.6	523.1 ± 121.2
β-hydroxybutyrate, ng/µL	42.3 ± 9.2	115.0 ± 39.2#

ALT, alanine transaminase; AST, aspartate aminotransferase. Mice were treated with saline or Form for 24 h, as described in materials and methods. Data are presented as means ± SE; n = 7 mice/group; *P < 0.05 vs. Ctr; **P < 0.01; #0.05 < P < 0.1.
