Several causes may induce change and atrophy in the bursa of Fabricius (BF). Databases on BF standards are available from published studies, however, updated references are needed to adjust the BF standards to present changes in highly specialized broiler genetic lines. The aim of this study was to evaluate BF-related measurements (weight and dimensions) under controlled conditions that would m...

For well over half a century, since the days of the imaginative and enthusiastic genius, Metchnikoff, it has been known that foreign materials cause inflammation.' When the material is a splinter in our finger, we take it for granted that the body will mobilize its phagocytes to react to the foreign material. Less well known is that soluble foreign proteins and polysaccharides ("antigens" in us...

Effect of catecholamines are studied on the bursa of fabricius of chicken. It is found that in epinephrine (E) treated chicken, the lymph follicles are slightly decreased in size. Some amount of nuclear pycnosis is visible in E and norepinephrine (NE) treated chicken. There is no change in the bursa weight and histology in NE treated groups. No deviation is observed in the level of DNA, RNA, to...

Semiquantitative scoring for subacromial bursa (SAB), subdeltoid bursa (SDB), and subcoracoid bursa by both gray-scale (GS) and power Doppler (PD) ultrasonography was performed in 15 patients with polymyalgia rheumatica (PMR) (72.6 ± 7.7 years old) and 15 patients with elderly onset rheumatoid arthritis with PMR-like onset (pm-EORA) (70.7 ± 7.0 years old) before starting treatment. The GS grade...

In the present study we confirm and extend previous reports about the existence of a T-dependent area in the bursa of Fabricius of some birds, analyzing ultrastructurally the cell content of the so-called diffusely-infiltrated lymphoid tissue of the bursa of the spotless starling, Sturnus unicolor. It consists of lymphocytes, plasma cells, macrophages (Mphis) and interdigitating cells (IDCs) in...

The aim of this investigation was to detect and examine the distribution of the CD3–T lymphocyte cell population of the Bursa Fabricius in chickens experimentally infected with Eimeria tenella. Slices of archived samples of Bursa were examined using the of direct peroxidase (DP) method. CD3–T lymphocytes were detected with human anti-CD3 antibody. They were localized in the cortico-medullary la...

Popliteal cysts occur commonly in both normal and arthritic knees. Most cysts are formed by distension of the medially situated semimembranosus bursa. Popliteus bursa distension occurs uncommonly as a lateral popliteal cyst. Two cases of rupture of lateral cysts which produced symptoms related to the anterolateral lower leg are reported. The difficulty of diagnosing the condition because of thi...
