This study investigated the effects of diphosphonates at scalar doses in a high bone turnover structure, namely, the proximal tibial metaphysis of rats. Arrest of bone modeling was represented by cylindrical-shaped metaphyses, increased height of the perichondrial bone bark, and persistence of primary metaphyseal trabeculae; these changes were dose-related. Higher doses of the inhibitors produced extension of the growth plate and arrest of the mineralization process. The dose-related dissociation between the effects on bone resorption and mineralization allows the therapeutic use of this class of drugs.

Abstract
This study investigated the effects of diphosphonates at scalar doses in a high bone turnover structure, namely, the proximal tibial metaphysis of rats. Arrest of bone modeling was represented by cylindrical-shaped metaphyses, increased height of the perichondrial bone bark, and persistence of primary metaphyseal trabeculae; these changes were dose-related. Higher doses of the inhibitors produced extension of the growth plate and arrest of the mineralization process. The dose-related dissociation between the effects on bone resorption and mineralization allows the therapeutic use of this class of drugs.File in questo prodotto:
