概括
呼吸道综合征的胸脑型狗具有比正常狗更大的 palatine 桃体和更多的炎症. 这些桃体变化可能会通过正手术解决,从而有可能避免桃体切除术.
科学领域:
- 兽医病理学 兽医病理学
- 比较解剖学的比较解剖学
- 狗BOAS研究研究 狗BOAS研究
背景情况:
- 脊髓阻塞性气道综合征 (BOAS) 在某些犬种中很常见.
- 桃体异常可能导致BOAS.
- 缺少对桃体的基因组学比较,可分为双脑型和正脑型的狗.
研究的目的:
- 为了比较来自胸头和脑状狗的口腔桃体的组织形态.
- 为了确定与BOAS相关的桃体的病理差异.
- 评估桃体切除术在BOAS治疗中的潜在作用.
主要方法:
- 从116只有BOAS的狗和11只正常脑的对照犬身上进行了口腔桃体的组织学检查.
- 使用了标准的组织学技术和数字显微镜.
- 桃体上皮质和淋巴卵泡的测量结果在各组之间进行了比较.
主要成果:
- 与对照人群相比,胸头桃体表皮质宽度 (48%更厚) 和淋巴卵泡面积 (52%更大) 显著增加.
- 脊髓上皮层内的中性质炎症在54%的桃体中存在,但在对照组中不存在.
- 这些发现表明,BOAS的狗的桃体具有显著的本病学差异.
结论:
- 胸头 palatine 桃体表现为淋巴细胞和上皮细胞增生,以及中性恋炎症.
- 这些变化可能是BOAS气道刺激的次要原因.
- 手术纠正BOAS可以解决桃体异常,可能使桃体切除不必要,这需要进一步的研究.

Pharynx
2.9K
The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

Cranial Bones: Lateral View
2.7K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Anatomy of Respiratory System I: Upper Respiratory Tract
2.7K
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract....
