Degree sum conditions of IM-extendable graphs are researched. The main results are as follows 1 Let G be a graph with 2n vertices. If for each pair of nonadjacent vertices u and v in G,, then G is IM-extendable. 2 Let G be a claw-free graph with 2n vertices. If for each pair of nonadjacent vertices u and v in G,du+dv≥2n+3, then G is IM-extendable.

AMs that collected, pured and cultured with contine method were stimulated by LPS of different concentration(0μg/ml,0.01μg/ml,0.1μg/ml,1μg/ml,10μg/ml) for 60min or by 1μg/ml LPS for different time stage (0min,5min,15min,30min,60min,120min) to observe the dynamic change of NF-кB intranuclear level and NO production, from which the best concentration and time point of LPS stimulation were selected. In the study, all AMs were divided into 4 groups: control group, group stimulated with LPS, group interrupted by Cal C and group inhibited by PDTC. The following parameters were measured: NF-кB level in nuclear protein extraction of AMs detected with sandwich ELISA, Inter-nuclear transposition of NF-кB observed with immunocytochemistry staining, NO content in cell culture medium quantitied with nitric acid reductase assay, Morphologic change of AMs in apoptosis observed with acridine orange staining and fragmentation at genome DNA of AMs detected with apoptotic electrophoresis assay.

It was shown that the absorption peaks of amine and amide groups of gelatin were shifted in HDPE/PE-g-MAH/Gelatin blends because of the reaction of PE-g-MAH with gelatin. The addition of PE-g-MAH made the increase of HDPE glass transition temperature. The compatibilizing effect of PE-g-MAH was due to the crystal compatibility produced by forming the co-crystals of HDPE, PE-g-MAH and PE-g-MAH-g-gelatin. The blends of EAA and gelatin were prepared by melting process and the compatibility of the blends was also studied. The FTIR results showed that absorption peaks of amine and amide groups of gelatin were shifted in EAA/Gelatin blends.
