摘要:
A purity of BZM is analyzed by a high performance liquid Chromatography (HPLC) to know whether the purity is qualified. And a quantity of a labeled ligand ([123I] IBZM) and a quantity of a free ligand (BZM) are analyzed by a liquid chromatograph tandem mass spectrometer (LC-MS/MS). The analysis result is used for maintaining a stable and qualified imaging agent. By maintaining the imaging agent, image interferences from background and receptor number are prevented.

摘要:
The present invention is related to a direct solid sample analytical technology for determining a content and a uniformity thereof in a lyophilized kit of a sulfur-containing chelator with a stable complex capacity for radiotechnetium (Tc-99m) and radiorhenium (Re-186, Re-188). An economical, stable and easily accessible coal standard is used herein as a contrast substance to construct a sulfur calibration curve, followed by obtaining the sulfur content and the uniformity thereof in the solid lyophilized sample by interpolating the foregoing result into the sulfur calibration curve. Then, the weight content percent is converted to get the content and the uniformity of the chelator in the lyophilized kit. The quality control of active pharmaceutical ingredients (API) in the lyophilized kit during key production processes and clinical applications is thus assured.

The invention discloses one glyco-molecular imaging method for grade classification of liver fibrosis and its glyco-molecular imaging agent. The agent combining with glyco-molecular imaging method for liver targeting could be used to differentiate the grade of liver fibrosis and follow-up evaluation of the therapeutic effect.
摘要:
The invention discloses an innovative process to produce highly antibacterial nano-composite fabric textile containing silver metal compound. The process mainly uses high-energy D-ray radiation to modify silver type of bactericides and graft or crosslink them onto Nylon or PET fiber surface to produce excellent antibacterial textile products. The mechanism uses silver nano-compound as performance additive and through Co-60 irradiation technique reduces and firmly fastens silver particles onto Nylon or PET (Polyethylene Terephthalate) fiber material. Because the inorganic silver type bactericides actively interact with enzymes in bacteria or destroy cell walls to achieve good bactericidal effect, the radiation process does not need initiators or other additives. So the process is simple and effective. The test results prove excellent bactericidal power and potential value in household or medical textile products.
摘要:
A method of single photon emission computed tomography (SPECT) using dual-isotopes of [99mTc]TRODAT-1 and [123I]ADAM is provided. Through SPECT, anomalies in dopamine and serotonin system are diagnosed with their photos in one examination. Thus, cost and labor for two examinations are saved and uses of SPECT are reduced.
