2 Fig. 1 Undecalcified bone sections with Villanueva bone stain. (A): Control (×100). (B): Al-NTA (×100). Severe increase of osteoid (★), indicating severe osteomalacia. (C): Fe-NTA (×100). Mild increase of osteoid (★), indicating osteomalacia. (D): Control (×100). Double tetracycline labeling (Arrow head). (E): Al-NTA (×100) No double labelings, suggesting almost complete cessation of bone mineralization. (F): Fe-NTA (×100). Decreased band of double labelings. Pathophysiology 1997 4, DOI: ( /S (97) )
