目的：研究兔骨髓基质细胞在体外培养条件下的成骨能力及生物学特性，探讨简便易行的成骨细胞体外培养方法，为组织工程选择理想的种子细胞来源。方法：取新西兰白兔骨髓液经离心后得骨髓单个核细胞，以1× 106／ml的细胞浓度进行培养，经传代培养，选择条件培养液培养(1640完全培养液中加入地塞米松10-8Smol／l，β-甘油磷酸钠10mmol／l，VitC 50μg／ml)作为骨髓基质细胞增殖和成骨的调节因子，通过倒置显微镜、HE染色、扫描电镜、碱磷酸酶(alkaline phosphatase，ALP)测定、Ⅰ型胶原免疫组化染色和四环素荧光钙染色等手段对获得的细胞进行生物学特性研究。

The histopathologic observations of corneas after penetrating keratoplasty in dogs: Thestructure of wholly transparent graft was the same as that of host cornea apart from the upperdonor-host junction where there was minimal irregularity of the corneal lamellae. However, thecorneal lamellae at the lower donor-host junction were neat. The graft with its central part beingtransparent only showed poor coaptation with recipient, in which the graft shifted inward and had marked wrinkles and folds in Descemet"s membrane. On the back of Descemet"s membranethere was hyperplastic stromal fibers that thickened the graft and partially adhered to iris.

5犬穿透性角膜移植术后角膜病理组织学观察完全透明的植片与植床结构一致，仅两者对合处上部纤维紊乱，而下方纤维排列整齐；中央透明的植片与植床对合不良，植片向植床方向嵌入，后弹力层皱缩、折叠，植片下方因有来自植床的基质纤维而增厚，部分对合处与虹膜粘连；浑浊的植片有比较完整的上皮层，植片约2／3深度的基质丧失原来纤维整齐排列结构，代以大量成纤维细胞增生。

Thermal behavior of PTT/PBT blends are studied. The results suggest that the presence of the less crystallizable PBT molecules in the PTT-rich (or PBT-rich) blends decreases the crystallizability and crystalline temperature of the blends. The complicated phase morphology of the PTT/PBT blends is strongly dependent on the compositions of the blends.

研究了PTT/PBT共混体系的热行为，以PTT为基质相的共混物，另一次要组分的加入降低基质相的结晶能力和共混物的熔融温度。

This paper studied on domestication of plantlets in tissue culture and rapid propagation of Dendrobium loddigesii Rolfe which dealed with the different medium composed of gravel, rotten soil, perlite, turves, sawdust and china clay, in the different light intensity and temperature. The results showed that the best selection of medium on the domestication was 10cm gravel in bottom, rotten soil + sawdust + perlite,(5:1:1) in the middle part ,5cm greenness bryophyte on the surface.the best selection of medium on the transplantaion of plantlets in vitro of bramble,and light intensity was employed harf overshadow by adumbral net,temperature confined 14℃－28℃.

本文研究了环草石斛组培苗炼苗的影响因素如光照强度，温度以及基质等，初步获得环草石斛组培苗炼苗生产技术：能进行人工光、温、水控制的如塑料薄膜大棚内进行环草石斛组培苗炼苗，光照强度的要求是使用遮阳网半遮阴；温度控制在14℃－28℃；出瓶苗要求株高2～5cm，叶片4～7，根数3～8；组培苗炼苗基质为底层是约10cm厚的碎石，在碎石上面是腐殖土+锯末+珍珠岩(5：1：1)，最上面是一层5cm厚的新鲜苔藓。

Abstract］ Objective To study the influence of different residual cornea bed of laser in situ keratomileusis on the collagenic construction of cornea through investigating the expression of matrix metalloproteinases and tissue inhibitors of metalloproteinases in cornea cells for different residual stroma bed after LASIK for six months.
