| Abstract: | β-calcium pyrophosphate has been used as a bone-graft extender. The present study evaluated the toxicity from the subchronic administration of β-calcium pyrophosphate to male and female Sprague-Dawley rats. Animals were divided into two groups consisting of 10 male and 10 female rats each and fed β-calcium pyrophosphate extract (30?mg/kg body weight/day) and saline, 7 days per week for 90 consecutive days. During the experiment, no deaths were observed in any groups, and there were no remarkable changes in clinical signs, body weight, food and water consumption, hematological and serum biochemical parameters, organ weight, and histopathological findings between the control and treated groups. The results show no adverse toxic effects of β-calcium pyrophosphate extract (30?mg/kg body weight/day) for rats of either sex. |
