RESUMO
Transforming technology for semi-synthesized isocorydione from the natural product ofisocorydine was studied. The factors affecting on the reaction yield were investigated. UV spectrophotometry was used to indicate the semi-synthesized yield of isocorydione. The optimum reaction conditions were determined as following: reacting for 12 h in the solution of sodium dihydrogen phosphate at pH 10, the temperature was 25 degrees C and the ratio of isocorydine to Fremy's radical was 1 : 2. Under the optimum conditions, the yield could reach up to 50.0%. The molecular structure of isocorydione was elucidated by X-ray single-crystal diffraction analysis for the first time.
RESUMO
In handling crises in hospitals caused by natural disasters like earthquake, systemati cpractical measures of crisis management are needed, which include: early contact with top managements for support in counter disaster supplies, immediate organization of temporary first aid stations by hospital staff, logistic support by full time personnel to solve problems such as drugs and medical equipments as well as food and drinking water, and psychological consultation to patients and staff members.
