Figure 2

Differential craniofacial growth in infant rats subjected to IH. Linear craniofacial measurements obtained from lateral and transverse cephalometric images of 2-week-old rats. Neurocranial (a), viscerocranial (b), mandibular (c), and transverse (d) parameters of normoxic (N) and IH group cephalometry. (e) Normalization of mandibular dimensions to tibial length in N and IH rats. Ratios of mandibular length (Co-Ll, Co-Me), ramus height (Co-Gn), and anterior corpus length (Mi-Ll) to tibial length were significantly smaller in the IH group than those in the N group. (f) Representative lateral radiographs of hemi-mandible from infant rat after one week of IH exposure. The abbreviations are explained in Fig. 2a and Tables 1A and 1B. Scale bar = 10.0 mm. Data are mean ± SEM for each group. *P < 0.05.
