Pyridoxine-deficient animals had tibias of reduced dry weight and cortical thickness. Histomorphometry demonstrated a disproportionately high eroded surface, lower amount of osteoid tissue and reduced mineralized trabecular width. Anterior\u2013posterior radiographs of the tibiotarsometatarsal joint showed reduced secondary ossification centres and coarse trabeculation. Decalcified metaphyseal cartilage showed irregular trabeculas and a markedly reduced amount of Fast-green counterstain matrix suggesting that there is less collagen present and in turn less availability for matrix to be laid down for later calcification. Plasma activity of the bone alkaline phosphatase isoenzyme (<jats:italic>EC<\/jats:italic>) 3. 1.3.1) was decreased. Plasma Ca and PO<jats:sub>4<\/jats:sub>levels did not vary. The present bone study referring to a pseudo-lathyritic state in which collagen maturation is not completely achieved supports the hypothesis that pyridoxine is an essential nutrient for the connective tissue matrix.<\/jats:p>","DOI":"10.1079\/bjn19940196","type":"journal-article","created":{"date-parts":[[2005,9,17]],"date-time":"2005-09-17T04:07:20Z","timestamp":1126930040000},"page":"919-932","source":"Crossref","is-referenced-by-count":26,"title":["Vitamin B<sub>6<\/sub>deficiency experimentally-induced bone and joint disorder: microscopic, radiographic and biochemical evidence"],"prefix":"10.1017","volume":"71","author":[{"given":"Priscille G.","family":"Mass\u00e9","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenneth P.
