The influence of interventional measures on metabolic factors in fluoride and aluminum combined poisoning bones.

This study aimed to evaluate the effects of soybean, selenium and spirulina on bone metabolic factors in rats with combined fluoride and aluminum poisoning.Methods:Sixty SD rats were allocated to five groups: A control group, a high-fluoride aluminum group, a high-fluoride aluminum plus soybean group, a high-fluoride aluminum plus selenium group, and a high-fluoride aluminum plus spirulina group. Serum samples were collected and radioimmunoassay (RIA) was used to measure osteocalcin (BGP), calcitonin (CT), parathyroid hormone (PHT) and insulin growth factor I (IGF-1) levels after 90 and 165 days of intervention. 1. When comparing the serum BGP level in the high-fluorine aluminum plus selenium group with the high-fluorine aluminum group, suggesting that the addition of selenium intervention was beneficial in reducing the effect of high-fluorine aluminum on bone homeostasis. 2. After 90 days and 165 days, the difference in serum CT levels between the intervention group and the control group was not statistically significant, suggesting an effect of the intervention factors.3. After 90 days of exposure, the three intervention groups had lower serum PTH levels (p < 0.00), inferring the efficacy of the interventions.4. After 90 days, serum IGF-1 levels were elevated in the Spirulina group compared with the high-fluorinated aluminum group, and the difference was statistically significant, suggesting that the addition of Spirulina intervention may counteract the inhibition of bone growth by high-fluorinated aluminum. The intervention of soybean, selenium, and spirulina can counterbalance the effects of fluoride and aluminum on bone metabolism and slow down the process of bone turnover.
