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，采用四环荧光标记法，观察探讨了引导牙周组织再生术后牙牙质形成过程中的化过程。

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.

结果得到金霉液相色谱图以液相色谱峰对应的一级质谱图。对谱图进行分析归纳,推测金霉中含有四环、差向异构四环和差向异构金霉杂质组分。
