The common marmoset (Callithrix
jacchus) is now widely used in various
research fields, including toxicology. However,
information about the background pathology of this
species is scarce. Here, we report a case of
rhabdomyosarcoma that spontaneously occurred in a
common marmoset. A 44-month-old male common
marmoset was euthanized due to bilateral hind limb
paralysis. At necropsy, a 2×2×5-cm intramuscular
mass was observed in the lower right back.
Histologically, the mass was mainly composed of
interlacing bundles of spindle-shaped tumor cells.
Immunohistochemically, the tumor cells were
positive for myogenin, desmin, vimentin and
alpha-smooth muscle actin. Ultrastructurally, the
tumor cells contained bundles of myofilaments with
Z-band-like structures. Thus, the tumor was
diagnosed as a rhabdomyosarcoma. To our knowledge,
this is the first report of spontaneous
rhabdomyosarcoma that was definitely diagnosed in
the common marmoset. 相似文献

天气越来越热,各种体外寄生虫也开始蠢蠢欲动。即使自己家中环境清洁,狗狗们也免不了会遭受到跳蚤一类虫子的侵害。因为可能在外出散步的时候,这些虫子就不请自来地跑到狗狗身上了。因此,春天除虫迫在眉睫,而比较通常采用的方法自然就是洗澡。 相似文献

Objective: To describe clinical and imaging findings, treatment, and long‐term outcome of cattle undergoing unilateral nephrectomy. Study Design: Case series. Animals: Cattle (n=10). Methods: Medical records (January 1991–August 2008) of cattle that had unilateral nephrectomy were reviewed. Follow‐up data were obtained by owner telephone interview. Results: Nephrectomy was performed without surgical complications. Transient increases in blood urea nitrogen and creatinine concentrations occurred after surgery and then returned to, or below, presurgical values in 9 cattle. Nine cows were discharged and 7 rejoined their respective herd as productive animals without long‐term complications. Conclusions: Ultrasonography was the most useful imaging tool for presurgical diagnosis. Based on our follow‐up data, unilateral nephrectomy resulted in few serious short‐term or long‐term complications, and cattle undergoing this procedure are capable of satisfactory growth, reproduction, and milk production after surgery. 相似文献

Lymphosarcoma in 10 New World Camelids 总被引:2,自引:0,他引:2

We evaluated the medical information from 10 New World Camelids with lymphosarcoma. Additionally, tumor tissue from 5 animals was examined by electron microscopy for evidence of retroviral particles. Lymphosarcoma was the most common neoplasm of New World Camelids in our hospital. Both llamas and alpacas, from 4 months to 15 years of age, were affected. Emaciation (7 of 8) and palpable masses (9 of 10) were the most common physical examination abnormalities, and a left-shifted leukogram (7 of 7) and hypoalbuminemia (6 of 7) were the most characteristic clinicopathologic findings. Lymphosarcoma was diagnosed by lymph node aspirate (n = 2), biopsy (n = 2), peritoneal fluid analysis (n = 2), or necropsy (n = 4). The clinical course after recognition of the disease was usually short, with a median survival of 1 month (1 week to 3 months). Organs with neoplastic infiltrates commonly included lymph nodes (n = 8), liver (n = 8), kidneys (n = 6), and lungs (n = 5). No retroviral particles were detected ultrastructurally. 相似文献

A 10-week-old, male, border collie-cross puppy was examined for an acute onset of unilateral vestibular signs. Neurologic deterioration was rapid over the next 12 hours and the puppy was euthanized. Rabies was diagnosed by histopathologic and immunohistochemical examination. 相似文献

Spinal arachnoid pseudocysts in 10 rottweilers 总被引:1,自引:0,他引:1
Ten rottweilers presenting with spinal arachnoid pseudocysts were investigated. In six dogs, the lesions were localised dorsally at C2-C3; in three dogs, dorsally and ventrally at C5-C6; and, in one dog, dorsally and ventrally at C6-C7. Clinical signs were consistent with focal compression of the affected spinal cord segments. The animals showed ataxia of all four limbs, with truncal ataxia and marked hypermetria in cases of C2-C3 involvement, or ambulatory tetraparesis in cases of C5-C6 or C6-C7 involvement. Other than signs indicative of spina bifida in one dog, no abnormalities could detected on plain radiographs. Myelography was used to define the localisation and extent of the pseudocysts. Additional information was obtained using magnetic resonance imaging in five dogs. Five dogs underwent a dorsal laminectomy; in three cases, the pseudocyst was treated by marsupialisation and, in two, by durectomy. 相似文献
