Columm temperature was 30℃. RESULTS The standard curve of dexamethasone phosphate sodium was linear over the range of 9.6~48mg·L -1. The calibration curve was Y=30605.6X+16315.8, r=0.9999. The average recovery was 98.1% with RSD 0.92%(n=9).
Method: The condition of human gastrointestinal tract was simulated, the hydrochloric acid(0. 1 mol·L-1) was served as dissolution medium in the first 2 hours, then the pH of the solvent was adjusted to 6.8 with phosphate sodium. The dual-wavelength spectrophotometry was used atΔA of 284 run and 268 nm to determine dissolution of the tablet.
3. The crude POD extraction of Sorghum and Brassica seedlings were electrophresis in LDS-PAGE, the POD active strips, detected by dyeing ofHAC-Benzidine, was cut and soaked in phosphate sodium buffer (O.IM pH7.4) containing 2ppm ZJ0777 overnight, a new compound was detected in HPLC (C18-ODS column).
Optimum study of technological parameters of electroless Ni is conducted by computer, through orthogonal design and with nickel phosphate, sodium sulfite and nickel citrate used as main constituents.
A blend system composed of potassium alkyl polyethylene glycol phosphate,sodium polyethylene glycol fatty alcohol sulfate,sodium lauryl sulfate,sodium sulfated castor oil with the mass ratio of 20∶10∶13∶10∶10 has the optimum effect to levelling performance on wool fiber.
Results The findings suggested that serum total calcium, phosphate, sodium increased significantly (calcium, phosphate P<0.1, sodium P<0.05 ), while serum potassium and chloride did not show any changes after the hypoxic exercise(P>0.05).
RESULTS: Corneal trauma resulted in miosis of eyes of rabbits. Diclofenac sodium 0.1% or dexamethasone phosphate sodium 0. 1% had an inhibitive effect on traumat-ic miosis and there were significantly differences(P<0. 01) of diclofenac sodium 0. 1% and there were no differences (P > 0. 5) of dexamethasone phosphate sodium 0.1% compared with experimental contrast group.
The enzyme was detected with the substrate β-glycerophosphate in sodium acetate acetic acid buffer form hemocytes (HC) and withp-nitrophenol phosphate sodium salt for HL, PM and HLS.

cDNA probes encoding preproenkephalin A (PPA) were used to detect the mRNA codings within the sections of adrenal glands of guinea pigs, processing according to the following procedures; perfused the animals with Zambonis' or 4% paraformaldehyde fixative; rinsed the block of adrenal glands for 12 hours in O.1mol/L phosphate sodium solution; the block were cut at -15℃ in a cryostat; Then the sections were prehybridized and hybridized with the biotinylated cDNA encoding PPA. The sections were incu...
The effects of matrices in sample solution separation in capillary electrophoresis were studied with benzyl alcohol, benzaldehyde and benzoic acid as solutes. The solutes were dissolved in sodium dodecyl sulfate, potassium dihydrogen phosphate-sodium tetrabo-rate and alcohol solutions, separately. It was shown that capillary electrophresis separation was affected by the matrix in sample solution. There were different relations for the ionic benzoic acid and nonionic benzaldehyde and benzyl...
A high performance liquid chromatographic method ispresented for the simultaneuous determination of dexamethasone phosphate sodium and its degradation product dexamasone in ocustilla decadronis. The chromatographic separation is achieved by using a MicroPakMCH-5-N-CAP(150 x 4 mm, 5 pm). The mobile phase consists of acetonitrile/water (32:68) with0.9 ml/L of 85% phosphoric acid. Under these conditions dexamethasone phosphate sodium anddexamethasone are eluted after 6.3 and 11.3 minute...
