Effects of MP on Bone remodeling: (a) No apparent differences in calcein single and double labeling (yellow and red arrows, respectively) were observed in male Water, LD PF, HD PF, and LD MP groups, though male HD MP showed increased calcein labeling. No apparent differences in calcein labeling were seen in female rats. Histomorphometric quantification showed significantly increased (b) mineralized bone surface (MS/BS) and (c) bone formation rate (BFR/BS) in HD MP male rats with no significant changes in female rats. (d) TRAP activity was measured to assess osteoclast activity in cortical bone. HD MP male rats showed increased TRAP staining in cortical bone relative to Water-treated male rats, whereas female rats did not show any apparent differences between Water and HD MP. Quantification of TRAP staining showed a significant increase in (e) number of osteoclast over bone surface (N. Oc/BS) in both HD MP treated male and female rats. HD MP treated male rats showed a significant increase in (f) TRAP volume over tissue volume (TRAP V/TV) in cortical bone.
