Mothods The sample Jasminodin was extracted with methanol and then the extract was chromatographed on silica gel GF254 plate with chloroform-methanol-water(10:3:1) as mobile phase and the chromatograms were scanned by using Shimadzu CS-930 dual wavelength TLCS in zegzag scanning mode at λ_s 370nm and λR 250nm. Results Callbration graph was rectilinear between 2.7μg^16.2μg per spot for the jasminodin. Conclusion Satisfa- tory results were obtained with the average recovery ratio of 99.76%,RSD 2.27%.展开更多

All studied subjects were lowland workers who were first time entry to Yushu for work at an altitude of 4 250 m. During the course of treatment,a routing physical examination was performed,AMS Lake Louise Scores were estimated,arterial oxygen saturation (SaO2),electrocardiography and hemoglobin concentration were measured before and after using RSJN for 10 days. In group A,the effective rate was 68 %,symptomatic improvement in 54 cases (90 %) within 5 days. In group B,the effective rate was 93 %,episodes of angina pectoris stopped in 12 patients within 3 ~ 7 days,one lasted 8 days. After treatment, the level of SaO2 increased 15.5 %,21.8 % and 5.6 % in group A,group B and group C,respectively. RSJN taken at the start of the arrival at Yushu can decrease AMS scores and facilitate cure. If taken after the illness has begun,RSJN may help lessen symptoms,especially effectively improved angina pectoris of the high altitude myocardial ischemic syndrome. Symptoms usually subside after 3 ~ 8 days. RSJN should be continually used for at least 7 days after ascent.展开更多

Simultaneously ammonium sulfate decomposes to some extent. During or after the dispersion, sulfate ion can interact with Fe atom on the surface of iron oxide to form a sort of surface sulfato complex of Fe and thus is transformed from the isolated into the bidentately bound form. Above 573 K the sulfato complex of Fe will gradually decompose with a further increase in temperature.展开更多
