The canal sealing ability was estimated by dye penetration test. The penetration depth of India ink into the OCP-mediated cement decreased significantly with time.

The defects were repaired even in the control group (defect only) within 4 weeks; however, the repaired cortical bone was thinner than that in the OCP/Gel-implanted group.

These conversion rates are obtained by performing a series of reactions between phosphate and sulfuric acid diluted from 10 to 50 wt% and with reaction times ranging from 10 to 50 minutes. The best conversion rate (38.78%) was obtained at a reaction time of 50 minutes with phosphate particle size of 80 μm and an acid concentration of 50 wt%.

It is worthwhile investigating the behavior of crystal growth, transformation and dissolution of OCP crystals under physiological conditions, with a similar concentration in inorganic composition to that of human blood plasma, to understand the affinity for living bone. We examined the behavior of OCP crystals after exposure to a simulated body fluid (SBF). No crystalline phase changes were exhibited by samples soaked in SBF, but formation of calcium phosphate was assumed to occur because of decreases in concentration of both calcium and phosphate ions in SBF. The molar ratio of the reduction in calcium and phosphate ions concentrations (ΔCa/ΔP) at 1 day was 1.42, eventually converging to a value of 1.33. These results indicated that OCP was formed on OCP crystals through an intermediate amorphous phase and OCP soaked in SBF was transformed into hydroxyapatite to only a negligible extent in the solution.

In the present paper the Hap was of a nanosized particle and peptide was poly-L-arginine (abbreviated to poly(Arg)) or copoly(L-arginine/ L-tryptophan = 4:1) (abbreviated to poly(Arg,Trp)). Physicochemical properties of these complexes were quite different with each other due mainly to the presence or absence of tryptophan residues on the polymer chain. The adsorption amount of poly(Arg,Trp) on HAp was much larger than that of poly(Arg). Zeta potential of the HAp-poly(Arg,Trp) complex was far lower than that of the HAp-poly(Arg) complex. Considering these facts, it was concluded that hydrophobic interaction between Trp residues of poly(Arg,Trp) induced an adsorption bilayer on HAp, while poly(Arg) simply formed an adsorption monolayer through electrostatic interaction. On the other hand, structural flexibility of a copolymer and its translocation through a lipid membrane were lower and slower in poly(Arg,Trp) than in poly(Arg).","PeriodicalId":20022,"journal":{"name":"Phosphorus Research Bulletin","volume":"387 1","pages":"39-44"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80788473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
