Plants involved in this association are most of the terricolous plants. The fungi related are classified in six genera of order Glomales, they are Glomus, Sclerocystis, Acaulospora, Entrophospora, Gigaspora and Scutellospora.

参与丛枝菌根形成的植物是大多数的陆生植物，参与丛枝菌根形成的真菌是隶属于球囊霉目6个属的真菌，即：球囊霉属、硬囊霉属、无梗囊霉属、内养囊霉属、巨孢囊霉属和盾巨孢囊霉属，它们共同的典型特征是在宿主根皮层细胞中能够形成树状的分支，即丛枝。

In the present study, the effects of 2 Hz and 100 Hz tetanic parameters on L-LTP of the field potentials were recorded from the layer Ⅱ/Ⅲ of the rat visual cortical slices in response to stimulation of the layer Ⅳ.

本研究用3周龄的大鼠视皮层脑片标本，在Ⅳ层刺激而在Ⅱ/Ⅲ层记录场电位，待场电位稳定后施加强直刺激诱导LTP，探讨2Hz与100Hz的强直刺激在诱发持续时间长于3h的L-LTP中的作用。

Methods: Low concentration and shortened time of trypsin digestion and mechanical dissociation were adopted to conduct culture.

采用低浓度、短时间胰酶消化和机械分离相结合的方法制备皮层神经元悬液，进行培养。

After amputation, the expression of desmin appears first in the distal end epidermis and the peritoneum 4 d PA. The expression in the peritoneum lasts to the 14 d PA when expression of desmin appears in the musculature, while that in the distal end epidermis only lasts to the 8 d PA when the connective tissue below begins to express desmin. Moreover, from the 4 d PA, musculature and epidermis of the tube foot begin to express desmin and the expressions last to the 20 d PA. From 8-14 d PA, musculature of the ambulacral plate expresses myogenin and the peritoneum also expresses myogenin from 14-20 d PA. All these results indicate that precursor cells for muscle regeneration in adult starfish A.rollestoni are mainly from the distal end epidermis and the parietal peritoneum.

创伤后第4 d，顶端表皮层及体腔上皮中首先出现了desmin表达，体腔上皮中desmin的表达一直持续到第14 d，此时其上方的肌肉组织中也出现了desmin表达；而顶端表皮层中desmin的表达仅持续到第8 d，同时其下方的结缔组织也开始表达desmin；此外，从第4 d起，管足肌肉及管足表皮层开始表达myogenin，且该表达一直持续到创伤后的第20 d；而第8 d起，步带板肌肉也出现了myogenin的表达，此表达一直持续到第14 d；从第14 d起，体腔上皮也出现myogenin表达，且一直持续到第20 d。

Total RNA samples used in Northern blotting were extracted from the light-exposed and light-interrupted cortex tissue of tuberous root of the two turnip cultivars.

Northern分析采用的RNA样品，是从上述两品种的光处理和暗处理的肉质根部周皮层中提取的总RNA。

The probes of CHS, PHYA, COP1, CIP7 and HY5 genes were synthesized by total RNA extracted from the cortex tissue of tuberous root of turnip, the probes of PAL and CHI were synthesized by total RNA extracted from the petal tissue of Eustoma, and the probes of AS were synthesized by total RNA extracted from the fruit tissue of strawberry.

采用的探针中，PHYA、COP1、CIP7、HY5及CHS基因的探针是利用芜菁的肉质根周皮层的总RNA合成，PAL和CHI基因的探针是利用草原龙胆花瓣的总RNA合成，AS基因的探针是利用草莓果实的总RNA合成。

Trichomes are unicellular or pluricellular outgrowth s from the epidermis of leaves, shoots, and roots

毛状体是叶片、枝条和根的皮层的单细胞或多细胞的外生物。

RESULTS: Four hours after operation, rats injected with bletilla particles developed temporary conscious disturbance, and sustained hemiparesis of contralateral limbs with spontaneous circling behavior. Ischemia or infarction was found obviously in the cortex of parietal, frontal lobes and basal nuclei of the right cerebral hemisphere, where the neurons characterized with vague outlines, pyknosis and necrosis of neuron nuclei were recognized as well. But hemiparesis and spontaneous circling behavior only lasted for 12 h after embolization with bletilla gum.

结果：白芨微粒组大鼠术后4 h内呈现意识障碍，持续性对侧肢体轻度偏瘫及环转，TTC染色显示右侧大脑半球额叶、顶叶皮层和基底核附近局灶性缺血或梗塞，光学显微镜下可见缺血区脑组织水肿或坏死，神经元轮廓模糊，核固缩或裂解等；白芨胶组仅在术后术后1 h内有轻度意识障碍，12 h内出现对侧肢体行动障碍，但未见明显病理改变。
