  • Publication number: 20070254847
    Abstract: The present invention provides a pharmaceutical composition containing steroidal saponins. The pharmaceutical composition comprises 5˜25 parts by weight of furostanal saponins represented by general formula A or general formula B and 1˜10 parts by weight of spirostanol saponin represented by general formula C. The present invention further provides a method for preparing the pharmaceutical composition. After determination of the three steroidal saponin components in the pharmaceutical composition of the present invention, it is proved that it has high stability and liability in its therapeutic effect. Meanwhile, the method to identify the three steroidal saponins is provided with reliable controllability. Besides, with its daily dosage of 300˜600 mg, which is less dosage, the drug of this invention provides a new choice in clinics.

  • Patent number: 7116653
    Abstract: The invention concerns a procedure to adapt the operating mode of a multi-mode codec to the changing transmission conditions in a CDMA mobile transmission network. The object consists of the coordination of the adaption of the codec operating modes in both transmission interfaces involved. This is achieved by a constant polling regarding the quality of transmission on the transmission segments during a communication connection, where a change in transmission quality for any unit involved in the transmission initiates a change of codec operating modes and where the present or future change in codec operating mode is passed to the other units involved in the transmission.
