Hydroxyapatite (Ca10(PO4)6(OH)2, HAP) particles have attracted a great deal of attention in biomedical fields due to their good biocompatibility, bioactivity and fairly broad applications as drug delivery, dental implant, bone cement, and etc. Thus, many researchers have made an effort to add new functionalities such as luminescence, drug delivery, and bone regeneration properties up to HAP powders by controlling their nanostructure as well as composition. In this research, the mesoporous strontium substituted HAP (Sr-HAP) microspheres were synthesized using a hydrothermal method. In this synthesis, aspartic acid monomers were utilized to form microsphere by controlling surface energy of HAP particles and Sr ions were substituted into Ca ion sites, which induced luminescence property in HAP powders. Moreover, the change in the amount of Sr substitution was found to influence the particle size, morphology, and concurrently surface area, which led to changing drug loading as well as drug release property. The amount of Sr influences the morphology, luminescent properties, particle size, surface area cell viability and drug loading property, which are investigated by SEM, TEM, XRD, FTIR, BET, XPS and in vitro test such as MTT assay and drug release test. In particular, the multifunctional Sr-HAP with molar ratios of 0.25 (Sr/(Ca+Sr)) possessed the strongest luminescent property as well as the superior drug loading and sustained release properties that were correspondent with large surface area and pore size. Our study indicates that the fabricated multifunctional Sr-HAP microspheres are quite useful for bone regeneration and drug delivery.

Objectives : In 『Treatise on Cold Damage Diseases』, the volume of preparation dosage measured in Hap was 6.5mL. This study aimed to confirm that a square-inch-spoon, which measures powder preparation dosage, was 1/3 Hap, and that Jeon-bi was 1/8 square-inch-spoon. Based on these values, this study also aimed to adjust the diameter of Firmiana-Seed-sized pill preparation, currently known as 6.5mm, so that one square-inch-spoon of powder preparation creates 16 pills. Methods : Calculated the ratio between the floor areas of square-inch-spoon and Jeon-bi and measured the ratio of volume; assumed that powder preparations were stacked as much as possible in the shape of a square pyramid when scooped comfortably, then calculated the slopes of 1/3 Hap and 1/4 Hap; measured the volumes of powdered Oryeongsan and Lijungwhan in square-inch-spoon and Jeon-bi; created the powders into Firmiana-Seed-sized pill preparation; adjusted the diameter of Firmiana Seed so that 16 pills could be created. Results : Inferring from the floor areas, the volume of square-inch-spoon is 9.2 times that of Jeon-bi; one square-inch-spoon should be 1/3 Hap for the powder to reach its maximum slope of 47° and, according to actual measurement of powder preparations, reach its maximum volume; when created into Firmiana-Seed-sized pill preparations, one square-inch-spoon should be 1/3 Hap so that approximately 16 pills were created. Conclusions : One square-inch-spoon of powder preparation was 1/3 Hap(2.17mL), Jeon-bi was 1/8 square-inch-spoon(0.27mL), and the diameter of Firmiana-Seed-sized pill preparation was 5.5mm.

Biphasic Calcium Phosphate (BCP) consisted of hydroxyapatite (HAp) and $\beta$-tricalcium phosphate (P-TCP) has been prepared by solid state reaction. The size reduction of the resultant BCP agglomerate was carried out by reaction with hot water under atmospheric condition uld also under high pressure using an autoclave. The influence of processing conditions on the change of crystalline phase and composition, relative amount of constituent, specific surface area, and microstructure was investigated by means of XRD, FT-IR, BET method using a nitrogen adsorption and SEM.

Preparation and heavy metal ion adsorption of sumicron hydroxy apatite were studied in this experiment. Submicron HAP was synthesized with Ca(OH)2 solution and H3PO4.Ca(OH)2 solution was made from water-quenching of CaCO3 heated at 1, 00$0^{\circ}C$ and 20%-H3PO4 was dropped into this Ca(OH)2 solution heated at 8$0^{\circ}C$. XRD pattern of prepared powder showed HAP crystal. The average particle size and sahpe of HAP were 0.25${\mu}{\textrm}{m}$ and sphere type. As a adsorbent, 1.0g of the prepared HAP powder in 1 liter of artifical 5ppm heavy matal waste water was sufficient, and more effective at pH7-9.

The Hydroxyapatite powders were prepared by Wet-direct and Hydrothermal synthesis using Ca(NO3)2.4H2O and (NH4)2.HPO4.Stoichiometric and good cristalline HAp powders were obtained 9$0^{\circ}C$ by wet-direct process. The aspect ratio of HAp powders prepared by hydrothermal synthesis was increased with increasing synthetic temperature. The HAp particles obtained at 20$0^{\circ}C$ for 10hr were needle shaped ultra fine crystals, about 100nm in size. Small amount of TCP was obtained above 80$0^{\circ}C$ after heat-treatment of hydrothermally synthesized HAp but good crystalline HAp phase was maintained up to 120$0^{\circ}C$ as the primary phase.
