A 2-year-old female shorthair guinea pig was presented to the Veterinary Medical Teaching Hospital, University of Wisconsin-Madison, for evaluation of a unilateral corneal opacity of 1 week duration. Physical examination revealed a markedly thickened right cornea and lymphadenopathy of the submandibular and prescapular lymph nodes. Cytology of a lymph node aspirate was highly suggestive of lymp...

BACKGROUND Linguatula serrata is one of well known members of Pentastomida which infects both human and animals. The aim of this study was to evaluate the prevalence of L. serrata in mesenteric lymph nodes, livers and lungs of camels slaughtered in Tabriz area, Iran. METHODS Mesenteric lymph nodes (MLNs), livers and lungs of 140 one-humped camels slaughtered in Tabriz, north-west of Iran were...

Bronchoscopy has the potential to propagate infections. Bacterial translocation was hypothesised to be the cause of infections observed following bronchoscopy and this study was designed to assess the risk of bacterial translocation following rigid bronchoscopy in rats. A total of 30 rats were evaluated. The study group (n=15) underwent rigid bronchoscopy. Arterial blood gas analysis was perfor...

There is a critical need for an alternative nonhuman primate model for inhalational anthrax infection because of the increasingly limited supply and cost of the current model. This report describes the pathology in 12 African green monkeys (AGMs) that succumbed to inhalational anthrax after exposure to a low dose (presented dose 200-2 x 10(4)colony-forming units [cfu]) or a high dose (presented...

Abstract Objective This study aimed to explore the pathological characteristics of lymph nodes around inferior mesenteric artery in rectal cancer and its risk factors impact on tumor staging. Methods 485 patients underwent proctectomy surgery were collected this study. Clinical features patients, including gender, age, BMI, size, type, differentiation, nerve invasion, nodes, marker, examination...

The four quarters of bovine mammary glands are completely separated and two quarters on each side (right or left) are connected to ipsi lateral supra mammary lymph nodes. It is not clear whether cells infused into the cistern of the mammary gland are capable of migrating to lymph nodes or the general circulation. To examine cell migration, a prescapular lymph node was removed from each of two l...

T cells are imprinted to express tissue-specific homing receptors upon activation in tissue-draining lymph nodes, resulting in their migration to the site of Ag entry. Expression of gut-homing molecules alpha(4)beta(7) and CCR9 is induced by retinoic acid, a vitamin A metabolite produced by retinal dehydrogenases, which are specifically expressed in dendritic cells as well as stromal cells in m...

OBJECTIVE High paraaortic lymph nodes superior to the renal vein are often involved by metastasis from advanced ovarian cancer, but are difficult to dissect. We developed a novel surgical technique for removing these nodes. METHODS The ascending colon is displaced from the right paracolic gutter. A retroperitoneal incision is made cranially from the ileocecal region along Monk's white line (f...

OBJECTIVE To assess the status of the regional and paraaortic lymph nodes in hilar cholangiocarcinoma and to clarify the efficacy of systematic extended lymphadenectomy. SUMMARY BACKGROUND DATA There have been no studies in which regional and paraaortic lymphadenectomies for hilar cholangiocarcinoma have been routinely performed. Therefore, the metastasis rates to the regional and paraaortic ...

the imaging assessment of nodal disease can be challenging for the radiologist because there are multiple sites to review and differing opinions about criteria for abnormal nodes. the ability to accurately detect nodal metastases is improved with knowledge of the criteria for abnormal nodes, the nodal drainage patterns, and common imaging pitfalls. in this article, we introduce these basic conc...
