Although numerous studies have demonstrated the ability of intestinal epithelial cells to produce PGs after infection with wild-type strains of Salmonella, few studies have focused on Salmonella-induced prostanoids in mucosal lymphoid tissues. This is surprising in view of the profound effects PGs can have on the host response. To begin to address PG production at mucosal sites, mice were orall...

we report a case of a 68-year-old female who was a known case of diabetes mellitus and chronic liver disease and presented with complaints of dry cough and other constitutional symptoms since one month. during initial investigations, the patient was found to have peripheral blood eosinophilia. upon investigating further,the patient was found to have mediastinal lymphadenopathy and fine-needle a...

This study examined the subsets of T lymphocytes in the thymus, spleen and mesenteric lymph nodes as well as the subsets of B lymphocytes in the spleen and mesenteric lymph nodes in mice administered chitosan adipate (20 mg/kg) intraperitoneally once or four times at 24 h intervals. The results showed that chitosan adipate decreased the percentage of immature CD4+CD8+ thymic T cells and increas...

Finishing pigs carrying Salmonella enterica are believed to be the main source of carcass contamination at the beginning of slaughtering. The aim of this study was to assess the S. enterica carrier status of finishing pigs at herd level by sampling pooled faeces on farm and mesenteric lymph nodes at slaughter in the North East of Italy. Environmental faecal samples belonging to 30 batches of pi...

OBJECTIVES The aim of the study was to detect micrometastases in lymph nodes in patients with rectal cancer following neoadjuvant therapy, staged node negative by routine histology. PATIENTS AND SETTING Mesenteric lymph nodes from patients who have undergone neoadjuvant therapy for rectal cancer were harvested during surgery. Nodes were bisected and one half was sent for haematoxylin and eosi...

The prevalence of yellow bodies was studied in superficial and deep lymph nodes in material from 46 necropsies. They were found in 22.8% of the 359 lymph nodes collected, ranging from 35.6% of the mesenteric to 11.1% of mediastinal lymph nodes, and were significantly more prevalent in deep abdominal than in superficial groups. Sets of lymph nodes from individuals tended to show an 'all or none'...

The size of the related lymph nodes and their histology has been correlated in 34 specimens of Crohn's disease. Granulomata were shown not to affect the maximum diameter of the lymph nodes nor to be more frequent in large nodes. The enlargement of lymph nodes appeared to be due to simple, non-specific, reactive changes. Granulomatous lymph nodes were found in 38% of all our cases of Crohn's dis...
