The histopathological appearance of the femoral head. a was from NS group which showed well arranged trabecula and normal osteocyte with nuclei. The red arrow demonstrates the normal bone marrow. b, c and d were from LPS/MPS group which showed empty bone lacuna, bone marrow necrosis, and broken trabecula. The blue arrow in b demonstrateds the empty bone lacuna. The black arrow in c demonstrates the necrosis of the bone marrow. The yellow arrow in d demonstrates the broken of the trabecula. At 8 weeks, E from LPS/MPS + NS group showed broken of the trabeculae. f was from LPS/MPS + PTH group which showed better arranged and more condense trabeculae compared with E.(HE stained; magnification,×100)
