Ultrastructural study of apatite precipitation in implanted calcium phosphate ceramic: influence of the implantation site.

abstract：:The mechanism whereby liposomal entrapment enhances the hypocalcemic effect of calcitonin (CT) was evaluated in the rat. Phosphatidylcholine (PC) and PC plus cholesterol (PCC) preparations of large multilammelar vesicles (MLV) and small unilammelar vesicles (SUV) were used to entrap human calcitonin (hCT). The effect ...
