(32) What is also deserving of note is that we found lamellar bone and Haversian
system in the HA/Zr[O.sub.2]/PRP-treated group.
(a) Section through the femoral shaft prior to flushing of bone marrow demonstrated a large network of the Haversian
and Volkmann canal system within the cortical lamellar bone.
Other animals' bones may behave differently due to the absence of Haversian
systems (e.g., Clifton et al.
Viable bone evident with blood vessels within Haversian
canals (d; and e;) and necrotic bone evident with empty Haversian
While studying the bone tissue, we drew attention to the osteons' shape, their location, the shape of the Haversian
canals' transection, osteons' transformation, and other issues, the description of which, undoubtedly, is important in the comparative histology.
The inner and middle cortex is heavily remodelled by Haversian
bone resulting from the secondary reconstruction of the primary periosteal bone.
As observed in humans, an important feature of NHP bone is the presence of osteonal or Haversian
remodeling in cortical bone (i.e., intracortical bone remodeling), which is not normally present in rodent bone (Jerome and Peterson 2001; Havill et al.
(9) Unaffected areas of the jaw in patients with BRONJ have prominent trabecular structures and smaller and fewer Haversian

The rubbery matrix found in people deficient of cholecalciferol does not provide sufficient trabecular and collagenous support but instead hydrates and expands the bone, causing an outward pressure on the internal Haversian
canals and external periosteal covering, richly innervated with sensory pain fibres.
