摘要:
A process for the recovery and purification of natural hydrophilic water-soluble products in conjugated form from vegetable aqueous extracts or physiological fluids, by adsorption of said extracts or fluids on a lipophilic resin, followed by desorption and recovery of the eluate, which process is characterized in that the resin is a porous styrene-divinyl benzene polymer brominated at the styrene and/or divinylbenzene portion, with 600 m2/g area, 1.3 ml/g volume (dry weight), about 200 Angstrom pore size.
摘要:
The present invention provides improved methods of differentiating insulin+, glucose responsive islet-like structures from insulin- cells. The invention further provides methods for using insulin+, glucose responsive islet-like structures, as well as the insulin+, glucose responsive cells which comprise said islet-like clusters.
摘要:
The invention provides methods of repairing damage to, or defects in, mammalian tissues or organs. In these methods, a particulate or non-particulate acellular matrix made from a tissue or organ other than the tissue or organ being repaired is placed in or on the organ or tissue that is being repaired.
摘要:
The invention relates to a method for extracting an extract, which contains the natural mixture of conjugated equine estrogens, by the liquid-liquid extraction of the mixture of conjugated equine estrogens. The extracted mixture is depleted of non-conjugated lipophilic compounds from the group consisting of non-conjugated flavonoids, non-conjugated isoflavonoids, non-conjugated norisoprenoids, non-conjugated steroids, particularly androstane and pregnane steroids, and comparable non-conjugated compounds.
摘要:
The present invention relates to a pharmaceutical composition for the treatment and prevention of cancer and the preparation method thereof, especially to a cell differentiation agent named CDA-II which is prepared by reverse phase chromatography of fresh human urine. The pharmaceutical composition is effective for the treatment and prevention of cancer. The active components in CDA-II contain differentiation inducers, differentiation helper inducers and an anticachexia agent, which act cooperatively to achieve the best therapeutic effect.
摘要:
Disclosed is a method to obtain an extract containing a natural mixture of conjugated oestrogens from mare's urine by solid-phase extraction of the mixture of conjugated oestrogens from pregnant mare's urine on non-ionic semipolar polymer adsorbing resins.
