METHODS: Costochondral graft reconstruction of the mandibular condyle was performed on the right sides in 6 male goats aged 6 months, while the left sides were left as control.

6只6个月龄雄性山羊左侧颞下颌关节作为正常对照侧，右侧手术切除髁突但保留关节盘行CCG（软骨长度3~5mm）重建髁突。

Multiple comparisons suggested that cotyledon with petiole or 1/4 piece of cotyledonary laminae from 7 days old aseptic seedling had much higher shoot regeneration frequency, reaching to over 90%.

多重比较结果表明，以7d苗龄无菌苗的带柄子叶或1/4子叶片为外植体较好，出芽率较高，达90%以上。

Of themwere treated group and 19 of them were controlled group, and stored at tempe-rature close to the cryoscopic point(-1℃～1℃)for 3 to 216 hours.

本研究选取49只6月龄乌珠穆沁羔羊为研究对象，其中19只为对照组，30只为处理组进行试验。

The growth influence of the Dactylopius confusus under temperature processingRaises the Dactylopius confususunder 21℃-33℃five temperature conditions,the research temperature to the grain various stadiums survival percentage,it\'s body size,the insect heavy and the bosom egg quantity and various insects\' condition growth experience time influence.

温度对胭脂虫生长发育的影响在21℃—33℃五个温度条件下饲养胭脂虫，研究温度对胭脂虫各龄期的存活率，胭脂虫成虫虫体大小、虫重和怀卵量及各虫态的发育历期的影响。

The brain tissue of the different fetal age rat could be cultured into neural stem cells with the most number of cells for 12.5 dags embryo, which furthermore differentiated into neurons and glial cells.

胎龄为12.5天胎鼠大脑皮质培养出的神经干细胞数量最多，可分化为神经元、神经胶质细胞及少突胶质细胞。

In sham-operation group,animals were decollated and their brains were taken out at 24 hours postoperatively. In all the groups, hippocampal brain injury was detected using histopathological method combined with semi-quantified RT-PCR methods for detecting caspase-3 mRNA. Adult rats aged 90 days were used in modified y maze to examine their learning and memory functions. All these three experiments were independent.

各组海马区脑损伤行组织病理学检测，半胱氨酸天冬氨酸蛋白酶-3 mRNA的表达采用半定量反转录-聚合酶反应方法进行检查，成年90 d龄的大鼠进行三等分迷宫测试其学习记忆能力，3个实验各自独立。

Its survival curve could be described by Deevey-Ⅲ.

云南红豆杉的存活曲线属于Deevey—Ⅲ曲线，该种群的死亡率曲线与消失率曲线变化趋势基本一致，均在龄级为110～130a和220～250a阶段出现第一和第二峰值。

The results showed that: 1 The survival curve of the population conformed to the type of Deevey-Ⅲ; 2 With an increase in the population mortality ratio and a decrease in the survival rate, the mortality ratio greatly increased in ages 0-40 years, reaching 89.7%; 3 There existed two peaks of mortality in the lifespan, one was from seedlings to young trees (0-40 years) and the other in the adult stage (180 years).

结果表明：1岷江上游林线地段岷江冷杉种群存活曲线趋於Deevey-Ⅲ型。2林线地段岷江冷杉种群生存率呈单调下降趋势，生存率下降趋势前期高於后期，说明岷江冷杉种群幼苗死亡率高，种群后期比较稳定。3林线地段岷江冷杉林整个生长期中出现了两个死亡高峰期，一个出现在幼苗向幼树过渡时期（0~40年），另一个出现在中龄时期（180年）。

The results showed that the number of young individuals was larger than that of middle aged and old individuals in the B. platyphylla population. The population had one peak of mortality in size class Ⅴ. The survival curve of the population appeared to be the Deevey-Ⅱ type. The population was a rise type at present.

结果表明：白桦种群幼年个体丰富，中老年个体相对较少，种群在第V龄级出现死亡高峰，种群存活曲线属于Deevey-Ⅱ型，白桦种群目前表现为增长型种群。

First 27 rabbits of the experimental group were destabilizated by operated on L6、7.Inj Diazepam 0.25 mg/kg,Inj Ketamine 0.02 g/kg and Inj Atropine 0.125 mg/kg was one by one injected into the rabbit through the auris vein,shearing the rabbit hair of backside waist,fixing the rabbit on operation table in face lying,using 1% Povidone Ioding to degerm the operation area.Every rabbit was incised at the backside of its waist,that incisal opening is located in the center of the intervertebral space (L6、7 space) that both side iliac crest line correspond ,from the meso-ordinate direction cut about 4 cm incision,cutting open skin and subcutaneous tissue,thoroughly ,exposing the spinous processes the vertebral plates and the upper-inferior articular processes,entirely segregating the muscles that cohere the spinous processes the vertebral plates and the articluar process,then excising the supraspinal ligaments and interspinal ligaments,biting off two sides the inferior articular processes of L6,in order that resulting in intervertebral destabilization,using 0.9% Inj.Sodium Chloride to washout the incisal opening,in order sewing up each layer tissues.

方法］ 取48只6个月龄日本大耳白兔，雌雄不限，体重为（2.5±0.2） kg，随机进行分组，分为对照组和实验组，对照组为21只；实验组为27只；先将实验组兔腰背部皮毛剪除，用安定注射液1.25 mg/kg、氯胺酮0.02 g/kg、阿托品0.125 mg/kg顺次耳缘静脉注射麻醉后，俯卧固定于手术台上，用1%碘伏消毒手术区域，以髂嵴平对椎间隙（即L6、7）为中心，从正中取一长约4 cm纵行切口，切开皮肤及皮下组织，锐性分离，暴露棘突、椎板及上下关节突，将附着于棘突、椎板及小关节的肌肉全部分离开，然后依次切除L6、7棘上及棘间韧带，咬除第6腰椎两侧下关节突，造成椎间失稳，用无菌生理盐水冲洗切口，依次缝合各层组织；术后动物在笼中自由活动。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
