The results showed that the glandular epithelial cells of serous acinus,the epithelial cells of all gland ducts and parasympathetic ganglion cells appeared GnRH positive in immunoreaction.The positive substance was distributed in the cytoplasma with negative nuclei.

结果显示，大鼠颌下腺的浆液性腺泡的上皮细胞，各级导管的上皮细胞及副交感神经节细胞均呈促性腺激素释放激素免疫反应阳性，阳性反应物质分布在胞质，胞核呈阴性反应。

Results: NGF and TrkA were mainly distributed in intercalated duct, striated duct, excretory duct cells in salivary gland tissues around neoplasm, proven by pale brown positive response in cell membrane and plasm. p75 was not only found in duct epithelial cells in salivary gland tissues around neoplasm, but also apparently in serous acinus plasm.

研究发现：肿瘤周围涎腺组织中，NGF和TrkA主要分布于闰管、纹管及排泄管细胞，表现为胞膜及胞浆呈棕黄色阳性反应。p75在肿瘤周围涎腺组织中，不仅分布于导管上皮细胞，浆液性腺泡胞浆亦呈明显的阳性反应。

The ideal time-saver for busy clinicians, this handy guide delivers a practical "how-to" perspective on diagnosis and treatment for a range of commonly encountered childhood infections—from otitis media, sinusitis, and urinary tract infection...to hepatitis, cervical adenitis, pediatric tuberculosis, pneumonia, catheter infection, and more.

面向忙的临床医师的理想的节时器，这方便向导交付一实际"入门"远景在诊断和处理为多种通常遇到的童年infectionsrom耳炎媒介上，窦炎和对肝炎，宫颈的adenitis，儿科的结核病，肺炎，导管感染，等的泌尿道感染。

This type of cancer is called ductal adenocarcinoma.

这类型的癌症是所谓的导管腺癌。

Simultaneous measurement of CORB and COTD were performed in following situations:(1)cardiac output was varied by manipulating inotropic drugs(adrenine, dobutamine, dopamine, verapamil);(2)under six different ventilatory settings:①volume controlled ventilation with tidal volume of 12ml/kg(VCV, VT 12ml/kg);②volume controlled ventilation with tidal volume of 6ml/kg(VCV, VT 6ml/kg);③pressure controlled ventilation with tidal volume of 12ml/kg(PCV, VT 12ml/kg);④pressure controlled ventilation with tidal volume of 6ml/kg(PCV, VT 6ml/kg);⑤volume controlled ventilation with high positive end-expiratory pressure.

1经肺动脉漂浮导管CVP腔注射肾上腺素、多巴酚丁胺、多巴胺、异搏定改变动物心肌收缩力，观察注射药物前、注射药物后CORB和COTD的相关性；(2)设置5组不同的机械通气参数：①容量控制通气，潮气量12ml/kg(VCV， VT 12ml/kg)；②容量控制通气，潮气量6ml/kg(VCV， VT 6ml/kg)；③压力控制通气，潮气量12ml/kg(PCV， VT 12ml/kg)；④压力控制通气，潮气量6ml/kg(PCV，VT 6ml/kg)；⑤容量控制通气，潮气量6ml/kg，高呼气末正压，PEEP为12~15cmH2O。

Results There were differences in shape and layers of velamen cell, number of xylem bundles, maximum diameter of vessels, organization of pith, as well as the types, quantity, and size of crystals. D. fimbriatum could be distingushed from its adulterant species D.

结果根被细胞的形状及皮层厚度，中柱的木质部束数、导管的直径、髓的构成，晶体的类型与大小存在种间差异。

The crystals exist in parenchyma cells of its petioles. Its petioles have big vessels and much aerenchyma.

叶柄薄壁细胞存在晶体，叶柄的导管管径比较大，有大量的通气组织。
