Figure 1.
Colonic temperature and oxygen consumption (VO2) responses of C57BL/6 mice to Na2S (doses indicated) and saline administered i.c.v. The changes in colonic temperature (a form of deep Tb) are shown in the upper panel, while the changes in VO2 (an indicator of thermogenesis) are depicted in the lower panel. Here and in Figures 2–5, n is the number of animals in each experimental group.
