CHU Gang, GAO Jing, LU Ying, DING Xue-Ying, GAO Shen
2006, (3): 142-144.
Abstract(2929) PDF (452KB)(686)
Abstract:
Objective : To construct pseudo-ternary phase diagrams of liquid crystal (LC) with lecithin of various purity and various ratio of lecithin to alcohol (Km). Methods : LC was prepared with lecithin of various purity as surfactant, isopropyl myristate as oil phase and anhydrous alcohol as co-surfactant. The LC configuration was determined with self-made polarization microscope. Results : The liquid crystal formation region was observed light with the polarization microscope. No liquid crystal appeared when the Km was 1 : 4, and in the same condition of 25℃ and Km, the liquid crystal formation region was larger with the lecithin purity increasing. At the same time, the changeable region of water proportion was also larger with the Km increasing. Conclusion : Constructing pseudo-ternary phase diagrams to discribe the factors of liquid crystal configuration is precise and simple.

Abstract(2216) PDF (346KB)(187)
Abstract:
Objective : To explore the mechanism of therapeutic effect of matrine on human gastric carcinoma by inhibiting the production of matrix metallo-proleinases of cell line MKN - 45 induced by it. Methods : The production of matrix metalloproteinases (MMP -2,MMP -9)of MKN -45 cells were measured by ELISA and gelatin zymogrmn. Results : In the dose of 5 -20μmol/L, matrine can significantly inhibit MMP-2 as well as MMP-9 expressions in MKN -45 cells. Especially, in the zymographic analysis of MMPs pxressions in conditional culture media, matrine 20μmol/L can greatly inhibit the MMP -2 and MMP -9 enzyme activity. Conclusion : Matrine could significantly inhibit the production and activity of MMPs in gastric carcinoma cell line MKN -45, which showed the inhibitory effect on the metastasis of gastric carcinoma cells.

Abstract:
Objective : To study antioxidalion effect of ethanol and aqueous extracts of Broussonetia paperifera fruits from 10 different habitats and assess their qualities by standards of China Pharmacopeia. Methods : MDA production in rats liver homogenate induced by auto-oxidation was measured by MDA kits method and the contents of ashes, elhanol and aqueous extracts were detected.

Abstract(1827) PDF (432KB)(344)
Abstract:
Objective :To optimize the formulation of the oral disintegrating tablets of trifluoperazine hydrochloride and compare its dissolution profiles with the marketing tablets. Methods : Orthogonal design was used to optimize the formulation of the tablets. The basket method was used to evaluate the dissolution profiles of the tablets. The content of trifluoperazine hydrochloride in the samples was analyzed by UV. Results : When the ratio of gelatia/mannitol/aspartame/trifluoperazine hydrochloride was 0. 15/1/0. 05/0. 16, the tablets has good mouth feel. When the content of crospovidone, L-HPC and microcrystalline cellulose were set at 8%, 5% and 30%, respectively, the disintegration time was within 15s. The cumulative dissolution of the tablets was more than 90% within 5 minute, respectively. Conclusion : The oral disintegrating tablets of trifluoperazine hydrochloride had the advantage of easy administratio-nand its dissolution was significantly higher than that of the market tablets.

Abstract(1763) PDF (324KB)(186)
Abstract:
Objective : To analyze the clinical curative effects of cefetamet pivoxil on acute urinary system infected patients. Methods :20 acute urinary system infected patients were randomly divided into two groups: group A(n= 10), in which the patients were treated with cefetamet pivoxil(250mg, po, bid, pc) for 7 days, and group B(n= 10), in which the patients were administrated with amoxicillin-clavulante (375mg, po, tid, pc) for7days. The clinical effective rate, recovery rate and WBC clearance rate in urine were statistically evaluated. Results : The clinical effective rates of group A and group B were 80% and 90%, respectively. The recovery rates of group A and group B were 70% and 80%, respectively. The WBC clearance rates in urine of group A and group B were 70% and 80%, respectively. One side effect case occurred in group B. There was no significant difference statistically between two groups (P > 0.05). Conclusion : Cefetamet Pivoxil is efficient to treat acute urinary tract infection.
