Abstract: The present invention is in the field of medicinal technologies, and provides a nano-material composition DG-5 for use as a medicament against drug-resistant bacteria. The composition showed a strong inhibitory effect against several super drug-resistant bacteria (superbugs), and thus can be used for manufacture of novel effective antibacterial drugs. The mediocament can be administered externally, orally, subcutaneously, or via intravenous or intramuscular injection.

Abstract: The present invention provided an anticancer nano-silver composition for the treatment and prevention of cervical cancer. The composition contains nano-silver powder 3-200 mg/kg, carbomer 700-1000 mg/kg, triethanolamine 700-1000 mg/kg, glucose 2.8-3.2 g/kg, and water as remaining; of the nano-silver powder, wherein the purity of silver is ?99.99% and particle size is 1-5 nm. Experiments demonstrated that the anticancer nano-silver composition can be used to inhibit HeLa proliferation, and cause cell death. The anticancer nano-silver composition of the present invention can be used to manufacture medicaments for the treatment and prevention of cervical cancer.

Abstract: The present invention provided an anticancer nano-silver composition for the treatment of lung cancer. The composition contains spherical nano-silver powder 12-200 mg/kg, pharmaceutically acceptable dispersing agent carbomer 700-800 mg/kg, triethanolamine 700-800 mg/kg, glucose 2.8-3.2 g/kg, and purified water as the diluent; of the spherical nano-silver powder, the purity of silver is ?99.99% and the particle size is 1-5 nm. Experiments demonstrated that the anticancer nano-silver composition can be used to inhibit proliferation of the human non-small cell lung cancer A549, and cause all cells death. The nano-silver composition of the present invention can be used in the manufacture of medicaments and for the treatment of lung cancer.
