The apply of Cosmopost ceramic posts in clinic / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To investigate the manufacture method and the effects of Cosmopost ceramic posts, to summarize the indications of Cosmopost ceramic post in clinic.</p><p><b>METHODS</b>228 pieces Cosmopost ceramic posts and cores were made for 96 patients. 2l7 pieces full ceramic crowns and 8 pieces full ceramic bridgs for Cosmopost ceramic posts and cores were made. The fitness of Cosmopost ceramic post were checked, and the color of all full ceramic crowns and full ceramic bridgs were checked in clinic. The amount of loosening and broken in all restorations were checked every year in clinic. follow up 2 - 3 years.</p><p><b>RESULTS</b>1 Cosmopost ceramic post was fracture about 1.5 mm before the full ceramic crown was worn. 227 pieces Cosmopost ceramic posts were perfect. All of the full ceramic crowns and bridgs for full ceramic posts were excellent in color. No loosening and broken cases were checked in 0.5 - 3 years. But the indications of Cosmopost ceramic posts were strict in clinic.</p><p><b>CONCLUSION</b>Cosmopost ceramic post has natural aesthetic effect and good strength. it can be used in clinic.</p>

ISOLATION OF AN ESTERASE PRODUCER TRICHOSPRONBRASSICAE AND ITS CATALYTIC PERFORMANCE IN KINETICRESOLUTION OF KETOPROFEN / 微生物学通报

A strain of yeast capable of hydrolyzing ethyl ester of racemic Ketoprofen with high enantioselectivity has been isolated from soil after two-step enrichment. The yeast was identified as Trichosporon brassicae. The process of growth and enzyme production was investigated. The catalytic performance of the resting cell of KET4 in kinetic resolution of Ketoprofen was also investigated. When the conversion of substrate reached 41% , enantiomeric excess of the (S) - Ketoprofen produced was 91 % , indicating a high enantiomeric ratio of 45.
