in this research,  300  pairs of lymph nodes; prescapular, prefemoral and popliteal were collected from lori – bakhtiari sheep in shahrekord abattoir. the specimens divided in two age groups (6 -12 month and 13 – 18 months) and then length, width and thickness of them were recorded using by caliper. for histological studies, lymph nodes were processed through routine tissue preparation techniqu...

Background: The purpose of this study was to assess the dose distribution and coverage of level Ⅰ-Ⅱ axillary lymph nodes during whole breast tangential field radiotherapy (RT) after breast-conserving surgery in patients with breast cancer. Materials and Methods: The level Ⅰ-Ⅱ axillary lymph node volumes were retrospectively contoured by a single radiation oncologist based on computed tomography...

We have estimated the macrophage content of different tissues of the normal adult mouse using F4/80, a highly specific antigen marker for mature mouse macrophages. An absorption indirect binding assay was used to quantitate F4/80 antigen against a calibration standard made from the J774.2 macrophage-like cell line. The richest sources of tissue F4/80 antigen were found to be bone marrow, spleen...

OBJECTIVE To evaluate perfusion of abdominal organs in healthy cats by use of contrast-enhanced ultrasonography. ANIMALS 10 young healthy anesthetized cats. PROCEDURES Contrast-enhanced ultrasonography of the liver, left kidney, pancreas, small intestine, and mesenteric lymph nodes was performed on anesthetized cats. RESULTS Typical perfusion patterns were found for each of the studied or...

We transferred peritoneal cells from BALB/c mice into C.B17 scid/scid mice. Six to eight months after injection, only cells with the B1 phenotype were retained in the spleens and peritoneal cavities of these mice. The lamina propria of the intestine contained many peritoneal, donor-derived, immunoglobulin A (IgA)-producing cells. The mesenteric lymph nodes of these mice were found to be a major...

Yersiniosis was prevalent among a caprine herd during the late autumn of 2003 in Iwate Prefecture, Japan. The disease affected 29 of about 100 lactating goats, but not dried or nonparous goats, mature male goats or kids. Four animals died within an epidemic period of 20 days. Affected animals developed decreased milk production with subsequent watery diarrhea, neutrophilia with increased band f...
