BMSCs were isolated from adult rats by modified bone marrow culture method. BMSCs were inoculated in basic medium containing 10%fetal bovine serum, high glucose DMEM, 100 U/L penicillin, 100 U/L streptomycin and 2 mmol/L glutamine in the control group. BMSCs were inoculated in conditioned medium (basic medium, 10 mmol/L β-glycerophosphoric sodium, 10-7 mol/L dexamethasone, 50 mg/L vitamin C).

在该实验条件下，果胶多糖酸水解后得到聚合度为2～16的果胶寡糖混合物，与质谱分析结果基本一致。

Fromthe point of view of chemical components,α-cellulose content for differentage-degrees bamboo is mostly the same,slightly increasing with the growth ofage,lignin content increases with the growth of age,the contents of extract,hemicellulose,polysaccharose,mineral elememts decrease with the growth ofage;the result shows the electric conductivity of bamboo is mainly decided bythe content of mineral elements,with the growth of age,volume resistivitybecomes great.pH value shows acid,acidity decreases with the growth of age,this is mainly due to the decrease of fraction of bamboo parenchyma with thegrowth of age.

从化学成分角度来说，不同年龄竹材α-纤维素含量差异不大，一般随着年龄增大而增大；木质素含量随着年龄增大而增大；抽提物、半纤维素、聚戊糖、灰分含量随着年龄增大而降低；研究表明竹材的导电性主要由矿质元素含量大小决定，随着年龄增大，体积电阻率越来越大；pH值呈酸性，酸性随着年龄增大而减弱，这主要由于竹材薄壁组织比量随着年龄增加而减少，内含物如淀粉减少，导致酸性减弱。
