Heart and lung weights and water content in 7N, 7CH, 18N and 18CH rats

	Heart weight (mg g−1)	Heart water content (% wet tissue wt)	Lung weight (mg g−1)	Lung water content (% wet tissue wt)
7N	0.62 ± 0.04	76.7 ± 2.5	0.88 ± 0.06	78.5 ± 2.0
7CH	0.63 ± 0.03	78.5 ± 1.1	1.13 ± 0.07*	78.8 ± 3.1
18N	0.55 ± 0.02	76.3 ± 2.5	0.74 ± 0.04	77.4 ± 0.8
18CH	0.85 ± 0.08**	74.7 ± 0.8	1.09 ± 0.05**	76.2 ± 1.0

Heart and lung weights are shown as dry tissue wt (body wt)⁻¹, while the water content of each tissue is shown as % wet tissue wt. Each value is shown as the mean ± s.e.m.

^**P < 0.01

^*P < 0.05, significant difference between 7N and 7CH or 18N and 18CH.
