[Preparation and performance characterization of pseudo-ginseng entrapped in crosslinked chitosan/polyacrylic acid/poly(ethylene oxide) nanofibrous membrane].

Objective: To prepare the cross-linked chitosan/poly(acrylic acid)/poly (ethylene oxide) nanofibrous membrance loaded with pseudo-ginseng and to determine its characteristics.

Methods: Pseudo-ginseng entrapped in chitosan, poly (acrylic acid), poly (ethylene oxide) nanofibrous membrane loaded with pseudo-ginseng was prepared by electrospinning and thermal treatment method. The surface morphology of fiber membrane was observed by scanning electron microscopy and the chemical structures were characterized by infrared spectroscopy; the thermal decomposition temperature was analyzed by the thermogravimetric analysis.

[Adverse drug reactions induced by Mailuoning injection: literature review on 162 cases].

To understand the adverse drug reaction (ADR) induced by Mailuoning injection. 162 ADRs due to the drug were retrieved from national medical journals of 1988-2007 for statistics. It was shown that there was no relationship between ADR and dosage, but ADR appeared mostly in middle-aged and old groups, and more in male than in female.
