  • Use of derivatives of succinate esters for the treatment of dementia
    Patent number: 7557089
    Abstract: The use of extract form Wangla (coeloglossum viride (L) Hartm. Var. Bracteatum (Willd.) Richter), succinate derivative esters, and a derivative and pharmaceutical acceptable salts thereof, for the manufacture of a pharmaceutical preparation for the treatment of dementia, particularly for the treatment of Alzheimer' disease and Vascular dementia. Through Animal experiment, it has been demonstrated that, succinate derivative esters can improve learning and memory ability in dementia rats induced by scopolamine and cyclohexenyl imine; improve learning and memory ability in dementia rats induced by ?-amyloid; improve learning and memory ability in dementia rats induced by permanent ligation of bilateral carotid; and improve memory ability of normal animals. It has the advantage of high activity, low toxicity and no inhibition to cholinesterase.

  • Method for improving channel transmission efficiency in wireless network
    Publication number: 20060153150
    Abstract: The present invention discloses a method for improving channel transmission efficiency in a wireless network. In the course of data transmission, a length of a data frame split from a Media Access Control (MAC) layer service data packet is changed in real-time according to a channel state of the wireless network. The inventive method for improving channel transmission efficiency in a wireless network can effectively improve the efficiency of wireless channel data transmissions and can be easily implemented.
