nineteen lymph node biopsies, 3 curetting, 15 blood samples obtained from patients with lymphadenitis and high titers of toxoplasma antibodies, and 27 tonsillar tissues removed from patients because of chronic tonsillitis were inoculated intraperitoneally into mice for isolation of toxoplasma gondii. toxoplasms were isolated from 5 lymph node biopsies, one curettage material, 2 tonsillar tissue...

PURPOSE To evaluate early variations in lymphatic circulation of the arm pre- and post-sentinel lymph node biopsy (SLNB) and conservative breast surgery by lymphoscintigraphy (LS). PATIENTS AND METHODS Between 2005 and 2012, 15 patients underwent LS before and after the SLNB (total=30 studies). The pre-SLNB study was considered the control. Early images within twenty minutes (dynamic and stat...

BACKGROUND Widespread use of flow cytometry for immunophenotyping in clinical veterinary medicine is limited by cost and requirement for considerable laboratory space, staff time, and expertise. The Guava EasyCyte Plus (Guava Technologies, Hayward, CA, US) is the first, personal, bench-top flow cytometer designed to address these limitations. OBJECTIVE The aim of this study was to adapt the i...

In experimental chronic ulcerative colitis induced by dextran sulfate sodium salt the morphological changes in mesenteric lymph nodes and the composition of lymphocyte subpopulations measured by flow cytometry were studied. In chronic ulcerative colitis the reactive changes in the mesenteric lymph nodes are characterized by follicular hyperplasia and sinus reaction. In chronic ulcerative coliti...

BACKGROUND Two mammary lymphatic cannulation models in sheep have been described with minimal use in the past 50 years. The purpose of this study was to investigate a new surgical technique to allow long term monitoring of mammary lymph flow and composition from the mammary glands, with rapid ewe recovery and minimal complications post-surgery. RESULTS We developed a modified methodology for ...

Lymphostatic edema associated with malignancies of the pelvis and abdomen is caused by treatment. Fundamentally, the treatment produces lymph transport impairment. While this is not usually associated with removal of the primary malignancy, it is associated with the accompanying lymphadenectomy and radiation therapy. This produces unilateral or bilateral lymphedema with or without genital edema...

One of the major prognostic factors in rectal cancer is lymph node metastasis. The formation of lymph node metastases is dependent on the existence of a premetastatic niche. An important factor preceding metastasis are lymph vessels which are located in the lymph node. Accordingly, the occurrence of intranodal lymphangiogenesis is thought to indicate distant metastasis and worse prognosis. To e...

Status of axillary lymph node is an important factor in staging, prognosis and guiding treatment selection in early breast cancer. Sentinel Lymph Node Biopsy (SLNB) is a revolutionary concept in solid tumor surgery which has been introduced since 1993 in breast cancer (Krag et al., 1993). SLN is the first lymph node (LN) which drains the lymph flow from the primary tumor site. Its careful exami...

Lymph flow is the primary mechanism for returning interstitial fluid to the blood circulation. Currently, the adaptive response of lymphatic vessels to mesenteric venous hypertension is not known. This study sought to determine the functional responses of postnodal mesenteric lymphatic vessels. We surgically occluded bovine mesenteric veins to create mesenteric venous hypertension to elevate me...
