This article describes the discovery of a chronic cervical wooden foreign body ventral to the left transverse processes of the cranial cervical spine using magnetic resonance imaging (MRI) in a dog that presented with chronic neck pain and lameness. The dog did not exhibit dysphagia or chronic draining tracts, the most common signs of the presumed cause, that of a penetrating oropharyngeal foreign body. The foreign body itself was represented on MR images as an oval straight-edged core within an inflammatory tissue reaction. The wood was slightly hyperintense on T2- and isointense on T1-weighted images relative to muscle. Surrounding this was a more conspicuous contrast-enhancing reactive tissue rim that was hyperintense on all pulse sequences. Adjacent musculature also exhibited diffuse edema and contrast enhancement that extended around the left cervical vertebral transverse processes and local intervertebral nerve roots. The foreign body was found to be a wooden stick upon surgical removal. MRI is an excellent method for visualizing the inflammatory tissue reactions associated with soft-tissue foreign bodies because of its contrast resolution and depiction of anatomy in multiple imaging planes.  相似文献

农业院校图书馆印刷型外文期刊利用状况的统计分析     

李国玲 《农业图书情报学刊》2011,23(4):117-120

在电子期刊蓬勃发展并日益得到读者青睐的新时代,馆藏印刷型外文期刊的利用率降低;更由于各高校图书馆的经费与存储空间有限,导致外文印刷型期刊在采购和收藏上存在很大的困难。通过对东北农业大学图书馆五年来读者阅览和复印外刊的变化统计,显示出印刷型外刊在广大的农业院校读者群中还有其存在的意义和作用,为各高校图书馆采购和收藏外刊提供可靠的数据依据。  相似文献

Removal of a metallic foreign body from the tongue of three horses     

M. Blatter  M. Thunig  F. Kretschmar  A. B. M. Rijkenhuizen 《Equine Veterinary Education》2021,33(4):e97-e103

The objective of this case report is to describe the diagnostic and surgical techniques for removal of a metallic foreign body in the tongue of three adult horses. The three horses were presented for evaluation and treatment of dysphagia and marked hypersalivation of 3–5 days duration. Radiographs of the head revealed the presence of a metallic foreign body in the tongue of each horse. The foreign bodies could be precisely localised under general anaesthesia using palpation and lingual ultrasonography and/or lingual radiography in combination with a forceps as a marker. The foreign bodies were successfully removed using laparoscopic instruments creating minimal soft tissue trauma. The use of long (43 cm) small laparoscopic (5 mm) instruments enabled good visualisation of the surgical field, providing optimal conditions for successful minimally invasive surgical treatment of horses with foreign bodies in the tongue. The three horses made uneventful recoveries and 12 months after surgery were eating normally and could be ridden with a bit as per usual routine. It was concluded that using long laparoscopic instruments in combination with palpation, ultrasonography and/or radiography allowed removal of the foreign body creating minimal soft tissue trauma and allowing optimal conditions for a fast recovery.  相似文献

现代女性视角的人文关注——论中国现代女作家对西方人文精神的审视和接受     

彭彩云 《湖南农业大学学报(自然科学版)》2010,(1)

中国现代文学是在全面、广泛接受外来影响的背景下产生和发展起来的,无疑,中国现代女作家的创作也受到了外来的冲击。但相比现代男作家,女作家对外来文学的审视有着自己独特的视角。她们关注并接受了西方女性人文主义,对女性自身的命运充满了关切和同情,明显带有女性意识。这些特点鲜明地体现在中国现代女作家的创作中,并影响到当代女作家的创作。  相似文献   

IMAGING DIAGNOSIS—URETHROVAGINAL FISTULA CAUSED BY A MIGRATING GRASS AWN IN THE VAGINA          下载免费PDF全文

Amalia Agut  Juana D. Carrillo  Agustina Anson  Eliseo Belda  Marta Soler 《Veterinary radiology & ultrasound》2016,57(3):E30-E33

A young intact female dog was presented with urinary incontinence. Abdominal ultrasound revealed the presence of hyperechoic linear structures within the cranial vagina suggestive of foreign material. A computed tomography (CT) retrograde vaginourethrogram demonstrated the presence of a fistulous tract between the urethra and vagina. A presumptive diagnosis of urethrovaginal fistula due to migration of foreign material was made. The grass awn was removed with vaginoscopic‐guided retrieval. Fourteen days later, surgical repair of the fistula and an ovariohysterectomy were done. This case report emphasizes the usefulness of CT for diagnosis and precise anatomical localization of genitourinary tract fistulas.  相似文献
