Values are means ± s.e.m. (N = no. of animals). Vv(mt), volume density of total mitochondria; all quantities expressed per tissue volume. *Percent organ mass for dogs from Davis et al. (1975). †Percent organ mass for rats from International Life Sciences Institute Risk Science Institute(1994). αsignificantly different from dog (ANOVA, P<0.05); δsignificantly different from rat(ANOVA, P<0.05); ωsignificantly different from harbor seal (ANOVA, P<0.05). Values with no s.e.m. were not included in the analysis and are presented for comparison.
