tetracycline

Abstract Guided Tissue Regeneration using collagen membrane was investigated by tetracycline fluorchrome labelling,which showed the dynamics of new alevolar bone and cementum formation.

对胶原膜引导牙周组织再生术后标本，采用四环素荧光标记法，观察探讨了引导牙周组织再生术后牙槽骨牙骨质形成过程中的钙化过程。

RESULTS The chlortetracycline's epimer, tetracycline and its epimer, as impurities in chlortetracycline have been determined by the liquid chromatogram and its first order mass spectrum.

结果得到金霉素样品相色谱图相色谱峰对应的一级质谱图。对谱图进行分析归纳,推测金霉素样品中含有四环素、差向异构四环素和差向异构金霉素杂质组分。
