AIM To determine the activities ofpolysaccharide extracts from Flammulina velutipes (Curt. ex Fr. ) Sing (FV), Lentinusedodes (LE) and Agaricus bisporus Sing (AB)on the proliferation of human hepatoma SMMC-7721 cells in vitro and on mouse implanted S-180tumors in *** The polysaccharide extracts were isolated from the fruit bodies of FV, LE and AB by the methods of hot-water extraction, Sevag’sremoval of proteins, ethanol precipitation,trypsin digestion and ethanol fractionalprecipitation. Human hepatoma SMMC-7721 cells were treated with 50 mg/L Polysaccharide extracts, and the mitosis index, mitochondria activity and cell proliferation were detected at different times in both control and experimental groups. The mice with S-180 implanted tumors were injected with the polysaccharide extracts at 24 mg/ kg body weight for 9 d and the tumorweight was measured on the 15th *** The mitosis index of hepatoma cells in vitro could be significantly decreased by treatment with the polysaccharide extracts fromthe three kinds of edible fungi (P ochondria activity of SMMC7721 cells treated with polysaccharide extracts were lower than those in control groups (P on rates of polysaccharide extracts against implanted S-180 tumors in mice were 52.8%, 56.6% and 51 .9% respectivelycompared with that in c0ntrol ***0N The PoIysaccharide extractsfrom the three kinds of edible fungi could inhibitnot only the Cultured malignant cells in vitfo butalso impIanted Sl80 tum0r i0 vivo.

Spectroelectrochemical Studies on Poly-o-phenylenediamine 1. In-situ Resonance Raman Spectroscopy

引用

Chinese Chemical Letters 1997年第2期8卷 171-174页

作者： Wu, LL Luo, J Lin, zh XIAMEN UNIV DEPT CHEMSTATE KEY LAB PHYS CHEM SOLID SURFACEXIAMEN 361005PEOPLES R CHINA

The structure of poly-o-phenylenediamine in the redox process has been studied using in-situ resonance Raman spectroscopy, in-situ UV-Vis subtractive reflectance spectroscopy and cyclic voltammetry. The results show that the structure of PoPD is dominated by a ladder polymer with phenazine rings, and at least three structures of PoPD are formed in the redox process. The three kinds of PoPD have different resonance enhancement effect, and the electronic structure of PoPD molecule is influenced obviously by protonation. The results also show that the most stable state of PoPD is its semi-oxidized state.

AN EXACT ANALYSIS oF THERMAL BUCKLING oF PIEZoELECTRIC LAMINATED PLATES

Acta Mechanica Solida Sinica 1997年第2期10卷 95-107页

作者： Shang, FL Wang, ZK Li, zh XIAN JIAoToNG UNIV DEPT ENGN MECHXIAN 710049PEOPLES R CHINA

In this paper, the governing differential equations of elastic stability problems in thermopiezoelectric media are deduced. The solutions of the thermal buckling problems for piezoelectric laminated plates are presented in the context of the mathematical theory of elasticity. owing to the complexity of the eigenvalue problem involved, the critical temperature values of thermal buckling must be solved numerically. The numerical results for piezoelectric/non-piezoelectric laminated plates are presented and the influence of piezoelectricity upon thermal buckling temperature is discussed.

A new modification for the shear lag model is given and the expressions for the stiffness and yield Strength of short fiber metal matri×composite are derived. These expressions are then compared with our experimental data in a SiCw/Al-Li T6 composite and the published experimental data on different SiCw/Al T6 composites and also compared with the previous shear lag models and the other theoretical models.
