sodium ester
3.The theological behavior of dilute solution of sodium-cellulose sulfatic half-ester (NaCS),with relation to the solute concentration,solvent species,temperature and shearing rate,has been investigated,compaied with that of partially hydrolyzed polyacrylamide (HPAAm).
4.HPLC was used for determining D 2 amino 2 (1,4 cyclohexadienyl) acetic acid sodium acetoacetic acid methyl ester enamine(Dane salt) of dihydrophenylglycine (DHDS) and its related substances with ODS column after hydrolysis. The mobile phase was pH 4.1 phosphate buffer. DL phenylalanine was used as the internal standard,205 nm as detection wavelength.
5.The dilute solution of Sodium-Salt of celluloes sulfate half-ester (NaCS) blended with polyvinyl alcohol (PVA) was studied by Ubbelohde viscometry at various conditions.
9.Methods Twenty-four rabbits of portal hypertension model (produced by partial ligature of the portal vein, weighing 2.0 to 2.5 kg) were randomly divided into control group (C), sodium nitroprusside group (SNP,S) and N-nitro-L-arginine methyl ester group (L-NAME, L) ( n =8 each). Intravenous anesthesia with pentobarbital, tracheal intubation and monitoring of blood pressure were made as routine.
