有肺的

Results Expressions of pDGF-BB chain and PDGFR-α mRNA were low at the pseudoglandular stage of day 18, reached the peak level at the canalicular stage of day 19 and the sacculate stage of day 21 of gestations, fell again in newborn rats, and then increased in adult rats.

结果 (1)PDGF-BB、PDGFR-α mRNA随胎龄增长而增高，高峰在19～21天，新生时表达减少，成年时又增高到接近胚胎晚期水平；PDGF-AA和PDGFR-β mRNA在胚胎晚期、新生与成年鼠肺中均有表达，不随胎龄增长而变化，肺内PDGFR-β的表达高于PDGFR-α。

Their behaviour,activity,hair,feces were not found abnormal.Their food-intake and body weight were without any obvious variation;(2) After the experiment periods of three months and six months,the hematology examination of rabbits in all Ogroups and in all B groups was not made with distinct difference;(3) The blood biochemical measurement values in Ogroups and in B groups were basically similar;(4) When the systematic thanatopsia of laboratory rabbits,one rabbit each in a high-dose O group and a B group demonstrated 2-3 yellow-white circular nodes as large as a green bean in lingula pulmonis sinistri.Ohter organs were not found of obvious pathologic changes;(5)With the histopathology examination,the pathologic change of lung tissue seem by naked eyes was a focal suppurative inflammation under microscope.

其行为、活动、被毛、粪便等未见异常，进食量及体重变化未见明显差异；(2)实验期3个月、6个月的血清学检查，各药膏组与空白药膏组比较无显著差异；(3)药膏组与空白药膏组的血液生化测定值基本一致；(4)各药膏组实验兔的系统尸检表明，用药期空白药膏组和高剂量药膏组各有一只实验兔的肺心叶有2～3个黄白色绿豆大小圆形结节，其他脏器未见明显病变；(5)病理组织学检查，肉眼见到的肺组织病变镜检为局灶性化脓性炎症，其他组织未见病理性改变。

BACKGROUND: Alloimmune lung injury, characterized by perivascular lymphocytic inflammation, lymphocytic bronchiolitis, and obliterative bronchiolitis, causes substantial morbidity and mortality after lung transplantation and bone marrow transplantation, but little is known regarding its pathogenesis.

背景：同种免疫肺损伤以管周淋巴细胞浸润、淋巴细胞性细支气管炎和闭塞性细支气管炎为特征，它在肺移植和骨髓移植患者中有较高的患病率和死亡率，但是其病因学目前知之甚少。

Normal term newborns were examined as control. In 34 cases, there were no retrohepatic hyperechogenicity and the X-ray showed normal. In other 6 cases the sonographic pattern was discrete linear echoes, and X-ray showed wet lung.

而40例正常新生儿，有34例在肝脾后未见任何回声， X线胸片提示心肺正常； 6例显示在肝脾后可见稀疏的中等回声， X线胸片提示湿肺。

The PSC was a rounded or elliptic mass in the lung. It had rim enhancement and irregular low hypodense areas in the center after contrast-enhanced CT, lobular sign and spiculated sign.

肺内圆形或椭圆形较大肿块，增强扫描肿块呈不规则环状强化，中央显示不规则密度减低区，酷似肉瘤的CT表现，而其边界不甚规则，边缘不光整，有分叶、毛刺等浸润表现时应考虑为肺肉瘤样癌之可能。

Pulmonary cavity in AIDS is usually located in lower lung lobes,is 2～4cm in length,has thickened wall,smooth inner wall,rough outer wall,halo sign,and hila and/or mediastinal lymph node enlargement.CT morphology have prompted role for the diagnosis of AIDS,but correct diagnosis should combined with clinical date.

2艾滋病相关性肺空洞病变多位于下肺，病灶长径多为2～4cm，空洞壁厚，内壁光整，外壁毛糙，易出现晕征，淋巴结肿大多见，CT形态学对艾滋病的诊断有提示作用，确诊需结合临床。

During the first two weeks after birth, the growth performances were not significant between the mutant mice and the normal ones, but after that, the mutant mice grew much slower. The differences were significant in the indexes of eyes, lungs, thymuses, and adrenal glands between the genders. At the same time, the differences were significant in the organ indexes, such as lungs, adrenal glands, uterine and testicles between the normal phenotype mutant mice and the abnormal ones. And these two kinds of mice showed different amount of hemoglobin and red blood cell.

结果：B6-Co小鼠不育率22%、平均产仔数5.62±2.55只、离乳成活率56.59±41.22显著低于正常的B6小鼠，而胎间隔29.50±10.50天比正常B6小鼠短。B6-Co小鼠出生后2周内生长发育与正常B6小鼠基本一致，2周后，其生长发育慢于正常B6小鼠。B6-Co小鼠雌雄间的眼球、肺、胸腺、肾上腺的脏器指数差异有统计学意义。B6-Co表型异常小鼠与B6-Co表型正常小鼠相比，肺、肾上腺、子宫、睾丸的脏器系数差异有统计学意义。B6-Co小鼠表型异常小鼠在血红蛋白和红细胞数量上异于B6-Co表型正常小鼠。

Results: B6-Co mice showed higher sterile rate, and significant lower average litter size and survival rate at weaning than the normal B6 mice, but the time interval between deliveries was shorter in the mutant population.

The differences were significant in the indexes of eyes, lungs, thymuses, and adrenal glands between the genders.

Definitely. Cigarettes contain a lot of carcinogens like nicotine and tar. The ad compares lungs to a sponge. If you could wring out the cancer- producing tar, that goes into the lungs of a pack-a -day smoker every year, this is how much you'd get

是阿，菸里面有许多尼古丁、焦油等致癌物质，这支广告就是如果把肺比喻成海绵，如果一天吸一包菸，一整年下来，肺中的致癌焦油真的可以挤出这麼一大杯焦油呢！

The lungs are divided into sections, or lobes, and contain a large system of air carrying tubes called the respiratory tree.

肺被分为肺片或肺叶，包括有一个巨大的空气运输管道系统，称为呼吸树状物。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
