Here is a purulent exudate in which the exuded fluid also contains a large number of acute inflammatory cells. Thus, the yellowish fluid in this opened pericardial cavity is a purulent exudate.

图示:化脓性炎

打开的心包腔内微黄*色的液体即为化脓性渗出物。渗出物内包含大量的急性炎细胞。

A purulent exudate is seen beneath the meninges in the brain of this patient with acute meningitis from Streptococcus pneumoniae infection. The exudate obscures the sulci.

急性链球菌感染所致化脓性脑膜炎患者脑膜下可见化脓性渗出物。渗出物使脑沟变浅。

The abdominal cavity is opened at autopsy here to reveal an extensive purulent peritonitis that resulted from rupture of the colon. A thick yellow exudate coats the peritoneal surfaces. A paracentesis yielded fluid with the properties of an exudate: high protein content with many cells (mostly PMN's).

结肠破裂死者尸检剖开腹腔显示广泛的化脓性腹膜炎一层又厚又黄的渗出物覆盖在腹膜表面。穿刺液显示:富含蛋白、中性粒细胞。

The PMN's seen here are in alveoli, indicative of an acute bronchopneumonia of the lung. The PMN's form an exudate in the alveoli. This patient had a "productive" cough because large amounts of purulent sputum were produced. The source, the neutrophilic alveolar exudate, is seen here.

急性支气管肺炎(小叶性肺炎)显示肺泡腔内大量嗜中性粒细胞。由于大量脓痰的产生,因此病人多咳嗽。

This radiograph demonstrates patchy infiltrates consistent with a bronchopneumonia from a bacterial infection. Typical organisms include Streptococcus pneumoniae, Staphylococcus aureus, Pseudomonas aeruginosa, Hemophilus influenzae, Klebsiella pneumoniae, among others.

X线检查显示的不规则的渗出性病变是与细菌引起的支气管肺炎相一致。引起该病典型的病原微生物有链球菌、葡萄球菌、绿脓杆菌、流感嗜血杆菌、克雷伯菌等。

 

The neutrophils are seen infiltrating the mucosa and submucosa of the gallbladder in this patient with acute cholecystitis.

急性胆囊炎病人胆囊粘膜及粘膜下层可见渗出的中性粒细胞。

At medium power magnification, numerous neutrophils fill the alveoli in this case of acute bronchopneumonia in a patient with a high fever. Pseudomonas aeruginosa was cultured from sputum. Note the dilated capillaries in the alveolar walls from vasodilation with the acute inflammatory process.

伴高热的急性支气管肺炎病人镜下可见大量中性粒细胞充满肺泡。痰液培养出铜绿假单胞菌。肺泡壁毛细血管扩张充血。

Extensive acute inflammation may lead to abscess formation, as seen here with rounded abscesses (the purulent material has drained out after sectioning to leave a cavity) in upper lobe and lower lobe.

广泛的急性炎症可导致脓肿形成,如图所示,肺上叶和肺下叶可见圆形脓肿(脓液排出后在切面上显示为空洞)。

The white arrows mark areas of abscess formation in the upper lobe of this lung. The liquefactive necrosis of an abscess is apparent, because the purulent contents are draining out to leave a cavity. On a chest radiograph, the liquefied central contents of an abscess can appear as an "air-fluid level".

肺上叶白色箭头所指脓肿。脓肿的液化性坏死物排出后留下空洞。胸部X线显示:脓肿中央显示气液平面。

Two much smaller abscesses are seen here, one at the upper center and one at the lower right. These could be termed "microabscesses". Abscesses can come in a variety of sizes. Perhaps the most common abscess is the pimple on the face of a teenager.

可见两个大量的小脓肿灶,一个位于中央上部,一个位于右下角。这些小脓肿称为微脓疡。脓肿大小不一,或许最普通的脓肿是青少年脸上的疖。
