OBJECTIVE: To investigate the biomechanical effect of PCHC on repairing cancellous bone defect.

目的：通过动物实验观察新型的骨修复材料多孔碳酸化羟基磷灰石水泥修复骨缺损的力学效果。

This system found in some animals, and most of the coelenterate porous, they are Camp fixation living or planktonic life, from either side of the body to stimulate feelings or obtain food.

这种体制见于部分多孔动物和多数腔肠动物，它们营固着生活或浮游生活，能够从身体的任何一面感受刺激或取得食物。

A cellulose cuprammonium solution was sprayed into the -40℃ frozen liquid containing 20% Silicone oil and 80% hexane to form microspheres contained fine ice crystals,then regenerated the cellulose with 40% H 2SO 4 cooled to -30℃,and the microspheres were modified with diethylaminoethylchloride,the cellulose porous microcarriers for animal cell culture were prepared.

将纤维素铜氨溶液喷洒至－40℃的硅油：正己烷＝1：4的冷冻液中形成含冰晶的微球，用－30℃、40％的H2SO4再生纤维素，并用EDAE盐酸盐修饰其表面，制成适合动物细胞培养的纤维素多孔微载体。

OBJECTIVE: To prepare the porous hemostatic starch, and to analyze its biocompatibility in animals.

目的：制备一种多孔止血淀粉，观察其在动物体内的生物相容性。

Fibronectin had more ability to promote cell adhsion than collagen type I under such circumstances,SEM micrographs showed that MSCs all had a spread-out appearance with uniform distribution on polymer substrates precoated with fibronectin or collagen type I .

通过样本连续切片，图像分析系统分析各组动物新骨形成'情况，显示应用多孔PLGA块状材料经1型胶原修饰后体内成骨明显优于对照组，表现在：1。

A strip-shaped incision was created in the right thigh, 1 cm length and 0.5 cm depth. PHS was implanted into the muscles of the mice in test group while the controlled mice were implated with nothing.

所有动物在右股划出长约1 cm，深约0.5 cm的条形切口，实验组将1 g无菌多孔止血淀粉填入其中，对照组不填塞。

In order to investigate the possibility of porous hydroxyapatite ceramics in the repair of skull bone defect, twenty-four rabbits were used. The bone defect model was created by operation to obtain a defect in parietal bone in a size of 1 cm x 1 cm. Filled the defect with HAC and methyl-methacrylate-syrene copolymer to fill the defect as control. At 1st, 2nd and 3rd months after operation, behavior of the rabbits was observed and then these animals were sacrificed and specimens were examined under microscope.

为了探索多孔羟基磷灰石陶瓷作为人工材料修复颅骨缺损的可能性，选健康家兔24只，切除颅顶骨造成缺损，分别用多孔HAC植片及无孔甲基丙烯酸甲脂－苯乙烯共聚物植片修复家兔颅骨缺损，于术后第1，2及3个月处死动物，进行术后反应及组织学观察。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
