New Findings from Chinese Academy of Science in the Area of Macrophages Reported

June 6, 2014



By a News Reporter-Staff News Editor at Health & Medicine Week -- A new study on Macrophages is now available. According to news reporting out of Shanghai, People's Republic of China, by NewsRx editors, research stated, "In an attempt to improve implant-bone integration and accelerate bone fracture healing from resisting osteoclastic resorption point of view, we have employed a novel procedure to develop a mesoporous silica nanoparticles/hydroxyapatite (MSNs/HA) composite coating onto stainless Kirschner wire substrate. Characterizations of the surface microstructures indicated enlarged specific surface area compared to HA-coated wires as control, thus the MSNs/HA composite coated implants are endowed with abilities to locally deliver biomedical substances and enhance fracture healing."

Our news journalists obtained a quote from the research from the Chinese Academy of Science, "Herein, zoledronic acid (ZOL) as a model drug, different doses of which were immobilized in the mesoporous coating toward decreasing osteoclastic resorption activity. The loading capacities of ZOL increased almost eight-folds to that of pure HA coating, and the introduction of MSNs obviously retarded ZOL release to achieve a more sustained release profile. After certain periods of osteoclast like cells co-culturing with ZOL contained wires, tartrat-resistant acid phosphatases (TRAP) staining of polynucleated cells and a pit formation assay were performed to investigate the ZOL dose-dependent anti-resorption activity."

According to the news editors, the research concluded: "The promoted local effect on osteoclasts will be of clinical benefit to support implant integration and bone repair."
