Thin leaf section were prepared from fresh tissues of YS-lnfected and healthy citrus plants, when observed under a fluorescence microscope (Type, Olympus AH-FL-2), a yellow fluorescence was distinctly observed in the YS-infected phloem tissues and not in the phloem tissuses of healthy plants and of those infected with tristeza, exocortis, canker, scab, greasy...

将健叶和黄龙病叶叶柄用保险刀片徒手切片，在透射式荧光显微镜下检查，可看到健叶叶柄的木质部导管细胞壁发黄色荧光，韧皮纤维细胞发绿色荧光，而病叶叶柄韧皮部中有1～多个鲜明的黄色或黄绿色荧光团块。这种特异性的荧光，在健叶柄韧皮部中是没有的，其它由病毒、类病毒、细菌、真菌等病原引起的病叶柄韧皮部中亦没有此种特异性荧光。

According to the observation of the microstructure of small diameter lumber with scan electron microscope, there are many bordered pits of the radial trancheidal wall in the small-diameter Larch, and most of them have pit film. The resin is not only in resin canal, but also in some trancheid and ray parenchyma cells. The drying defects of small-diameter Larch lumbers were the most severe in consecution heating, fluctuating-heats 2h in between, and drying defects were nearly not observed in fluctuating-heats 6h. There is tylosis in the vessel of the heartwood of small-diameter Cathay poplar. The bordered pits of the radial trancheidal wall are dense, and the pits between vessels are alternate, most of them have pit film. Different collapse happened in all the small-diameter Cathay poplar lumbers. The collapse of small-diameter Larch lumbers was the most severe with consecution heating, fluctuating-heats 2h in between, the least with fluctuating-heating 6h.

通过扫描电镜观察发现，小径木落叶松的径壁具缘纹孔数目较多，且多具纹孔膜，小径木落叶松除在树脂道中含有树脂外，在一部分管胞胞腔内以及一些木射线细胞中也含有树脂，在产生缺陷的小径木落叶松锯材中，连续加热方式下锯材的开裂缺陷最为严重，波动2时次之，波动6时几乎没有开裂现象；小径木大青杨心材导管中的层状浸填体含量较多，且径壁具缘纹孔较为密集，管间纹孔呈互列方式，绝大多数纹孔具有纹孔膜，干燥后的小径木大青杨锯材均有不同程度的皱缩现象产生，其中连续加热干燥试验锯材的皱缩现象最严重，波动2时次之，波动6时干燥试验锯材的皱缩缺陷最小。

Methods Through eustachian tube we draw out effusion of tympanum and poured liquid medicine into tympanum under nasal endoscope.

方法于鼻内镜下经咽鼓管导管抽吸出鼓室内的积液并注入配制的麻黄碱混合药液，进行冲洗及留存。

Methods:Paticipants consisted of 32 simple VSD patients and 27 simple PDA patients excluded of any other diseases by physical examintation and electrocardiogram and x-ray. Patients were suggested echocardiography before and one week after the surgerys. Parameters such as Left ventricular ejection fraction、Fractional shortening、Left ventricular end-diastolic dimension、Left ventricular end-systolic dimension、Heart rate and Aortal velocity peak were measured.further more ,the Tei index which is originated from Pulse-wave Doppler and Tissue-Doppler Imaging were also calculated under ECG monitoring.

研究对象与方法：研究对象分别为排除其它心脏疾患的单纯动脉导管未闭患儿及单纯室间隔缺损患儿，手术治疗前后于心电监护下先行常规超声检查，获取心率、R-R间期、左室射血分数、主动脉峰值流速、左室收缩末期内径及左室舒张末期内径等值，并分别利用频谱多谱勒及组织多谱勒法测取患儿左室Tei指数(即PW-Tei及TDI-Tei)，多次测量并取其均值。
