Prevention of osteopenia induced with a gonadotropin-releasing hormone agonist in rats.

abstract：:Cortical bone can be modeled as a complex hierarchical composite interrelating both structure and material properties on four levels of structural organization: molecular, ultrastructural, microscopic, and macroscopic. In young animals, the microstructural systems are long parallel lamellar units, plexiform bone, whic...
