The result showed:leptin level was positive related with the level of E2,P in mammary only duringthe pregnancy,leptin level was positive to the level of Prl GH during the pregnancy-lactation cycle Hint:leptin in mammary might promote the development of mammary duct and gland bubble with E2,P;leptin in mammary might promote the mammary development and start secretion of milk with Prl; leptin in mammary and GH were promoting the growth during mammary developmen,strengthen the action to promote the gland bubble development with Prl,mighe play an important role in the modulation of the mammary gland development.

提示，乳腺组织leptin很可能在妊娠期协同E2、P作用于乳腺导管和腺泡的生长发育；乳腺组织leptin与Prl很可能共同在青春期和妊娠期促进乳腺发育及在妊娠末期启动泌乳，乳腺发育过程中乳腺组织GH很可能与乳腺组织leptin共同发挥其促生长作用，加强Prl在妊娠期的促进腺泡发育的作用，直接或间接的调节乳腺的发育。

En face views of the secundum ASD and perimembranous and outflow tract or doubly committed subarterial VSD were imaged on the interatrial septal section and inflow and outflow interventricular septal section at parasternal or apical position,respectively.

近年来发展起来的先天性心脏导管介入治疗，对超声心动图提出了更高的诊断要求，不仅需要准确的疾病诊断，更希望能全面了解房间隔缺损和室间隔缺损的形态学[1，2]，为治疗提供更精确的信息。

The inhaled air is made humid by the lachrymal fluid , this fluid is formed by the glands in the eyes ,.it comes continually to the nose through the nasolacrymal duct .

泪腺中的分泌物使呼入鼻腔的空气变得湿润，这些分泌物源源不断的通过特殊的导管从泪腺中输入到鼻腔中。

The degree of lignification varies from slight in protoxylem to heavy in sclerenchyma and some xylem vessels, but values of 25-30% lignin and 50% cellulose are average.

不同部位的木质化的程度不同，原生木质部中只有轻微的加厚，而在厚壁组织和一些木质部导管中则进一步加厚，平均含25％-30％的木质素和50％的纤维素。

The results showed that POD activity increased at first and then decreased in the skin and flesh of root. The peak occurred at 40 d and 60 d in the skin and flesh, respectively. POD activity in the skin was higher than that in the flesh at 30 d and then contrary results were observed. The higher POD activity was, the more POD isoenzyme was. The pattern of POD isoenzymes was different between skin and flesh at different vegetative growth stages. POD isoenzymes in the skin were composed of five monomers and four dimers while five dimers or two monomers, two dimers and one tetramer in the flesh. POD isoenzymes in the root were mainly acidic. POD localized mainly in the cell walls of periderm, cambium, xylem ray, xylem vessels and primary xylem.

结果显示，心里美萝卜营养生长期肉质根的皮和肉中POD活性均先升高后降低，分别在播种后第40 d和60 d出现峰值，30 d时皮中POD活性高于肉，之后则相反，酶活性最高时同工酶数目也最多，不同时期，皮和肉中同工酶种类不同；皮中POD同工酶由5个单体和4个二聚体组成，而肉中由5个二聚体或2个单体、2个二聚体和1个四聚体组成，均以酸性同工酶为主；组化定位显示POD主要分布在肉质根的周皮、形成层、木射线、木质部导管和肉的初生木质部等的细胞壁附近。

As the plants grew for a longer time the cells in the phellem of the taproots become smaller in size and closer in arrangement and calcium oxalate crystal declined in quantity in the phelloderm of the taproots all the taproots had three secretory canals but on average the calibers of the canals gradually become smaller the parenchyma cracks in outer phloem and the xylem part near the root center gradually increased in size ,and the area ratios of phloem to xylem continuously decreased the vessel and vessel-layer numbers in secondary xylem of the transplanted .

不同生长年份的移山参主根结构具有一定差异：随生长年份的增长，木栓层细胞体积变小，排列趋于紧密；栓内层草酸钙结晶越来越少；分泌道均为3轮，但平均口径逐渐减小；韧皮部外侧和木质部靠近根中央处的薄壁组织的裂隙逐渐增大；韧皮部与木质部的面积比则不断下降；12年，16年生移山参主根次生木质部中导管数量和层数明显多于8年生。

Mangium is of the greatest average vessel length, which are 1179.6μm and 333.1μm respectively. Fiber morphology of all four Acacia species is in accord with the requirement on pulping and papermaking so the 4 Acacia timbers can be used for pulpwood.

结果表明，厚荚相思的纤维平均长度最大为1179.6μm，而马占相思的导管平均长度333.1μm为最大。4种相思木材的纤维微观形态可以满足制浆造纸的要求，可以作为纸浆材使用。

Compared with the previous experiment model, this model which adopts the pressure Saccule to create gradually the pressure on the cervical spinal cord has its own advantages as follows: simple to operate, safe to carry out, successful rate is higher; cheaper catheter to obtain, oppressing the machine creation the convenience; to achieve the purpose that gradually pressure on the ventral lateral spinal cord, the medical screenage and electric physical examination reflect accurately the degree of the chronic pressure on the spinal cord; the change of Pathologic histology with the impediment on spinal cord function is similar to in the characteristic changes that of human CSM. ideally simulated the pathological procedure of the gradual chronic pressure in the course of the breakout of the CSM.

与既往实验模型比较，此模型采用压力球囊法致慢性颈脊髓压迫具有以下优点：手术操作简单易行，安全性及成功率较高；导管廉价，压迫器制作方便；达到了渐进性压迫的目的；影像学及电生理检测比较准确地反映了慢性颈脊髓压迫的程度；脊髓功能障碍后脊髓病理组织学改变类似于人类脊髓型颈椎病的特征性改变；较理想地模拟CSM发病中的慢性渐进性压迫的病理过程。

The bacteria culture was done for the endotracheal tube, the expiration and inspiration entrance of the anesthesia machine, and the soda lime in eighty general anesthesia patients. Results There are no bacteria growing in the new and the polluted new soda lime at the different stages.

对麻醉机的CO2吸收剂钠石灰进行不同时期细菌培养，菌株污染新的钠石灰进行菌落计数， 80例气管插管全身麻醉病人在手术麻醉结束前对病人的气管导管端、麻醉机的呼气端、吸气端、钠石灰行细菌培养。
