Research progress on derivatives of fucoidan / 国际生物医学工程杂志

Fucoidan is a kind of sulfated polysaccharide with a variety of biological activities.Chemical modification of polysaccharides can improve their bioactivities or make them produce new activities.In order to improve research of fucoidans and gain new polysaccharide drug with high bioactivity,this paper reviews preparative techniques and bioactivities of fucoidan derivatives,including low molecular weight fucoidan,desulfated fucoidan,oversulfated fucoidan,acetylated fucoidan,benzoylated fucoidan,phosphorylated fucoidan,aminated fucoidan and so on.

Correlative Study between Doppler Ultrasound Monitoring the Changes of PulmonaryHeart Diseast Patient' s Finger Artery Hemodynamics and Blood Oxygen / 医学研究杂志

Objective To explore the changes of finger artery hemodynamics of patients with pulmonary heart disease, at the same time to search for the relationship with PaO_2.Methods We used American ACUSON128/xp10 and ATL5000 color Doppler ultrasound diagnostic instrument to detect double middle - finger artery hymodynamics items; VSMANX, VDMIN,TAMX , PI and RI. We used Danish ABL5 artery blood gas analysis to monitor PaO_2 and SaO_2.Results PaO_2 ,SaO_2, VSMAX,VDMIN ,TAMX,and PI in control group,pulmonary heart disease remission stage, active attack stage had significant difference (P
