3.THE CRYSTAL STRUCTURE AND MOLECULAR ABSOLUTE CONFIGURATIONS OF BIS [N-(5-CHLORO-OXID-BENZYLIDENE)-α-PHENYLETHYLAMINE] PALLADIUM(Ⅱ)
4.Objective To study APA microcapsulized bovine chromaffin cells (BCCs) subarachnoid transplantation on the changes of neural nitric oxid synthase(nNOS)in spinal cord of chronic constriction injury (CCI)rats.
5.Methods:The serum concentrations of endothelin(ET)、angiotensionⅡ(AngⅡ)、nitric oxid(NO)、adrenomedullin(ADM)and urinary albumin excretion rate(UAER)were measured in 40 diabetic patients with nephropathy before and after treatment with shuxuening.
6.Objective To analyse vascular endothelial growth factor (VEGF), inducible nitric oxid synthase (iNOS, NOS2) and endothelial nitric oxide synthase(eNOS,NOS3) expression in giant cell tumor of bone(GCT) and their relation to angiogenesis.
7.In the process of Au &Ag leaching by cyaniding method,through examin ating and comparatively analysing the effect on the cyaniding method by the oxid ants such as H2O2、CaO2、CaClO3、BaO2 and KMnO4,we obtaind the best oxidant BaO 2 which separates stably, uses up less cyanide and best promotes dissolution and thus a qualified oxidant is availble for bold ore which is difficult to leach.
8.Using TiO 2 as addition agent, the ethanol conversion is 83% and the selectivity to ethyl acetate is 57% at 300℃ and 2.0h -1 for one step synthesis of ethyl acetate from ethanol on Cu/ZnO/CoO/Al 2O 3 oxid catalyst. This is attributable to collaboration action between catalyst and TiO 2 having acid base bifunctional catalysis.
