The present study was performed to investigate the protective effects of granulocyte macrophage-colony stimulating factor (GM-CSF) against ulcerative mucositis in hamster buccal pouch. GM-CSF was topically administered to the buccal pouches of hamsters with two different doses of 5 and 20 microg/ml. The treatment of GM-CSF led to rapid healing effects in gross and histopathological findings. It decreased expression of pro-inflammatory cytokine mRNA levels in the mucosal tissue of buccal pouches. Also GM-CSF-treated animals showed high numbers of Ki-67 positive cells in basal cell layer. These results suggest that GM-CSF provided excellent healing effects to ulcerative mucositis in the buccal pouch of hamster.

Background: Timolol is a beta-adrenergic blocker that has been shown to be effective in the healing of wounds. Oral mucositis (OM), an acute inflammation of the oral mucosa, is a bothersome side effect of some regimens of chemotherapy in which the oral mucosa becomes ulcerated. The current study aimed to evaluate the prophylactic effects of timolol mouthwash in preventing OM in adult patients receiving chemotherapy compared to the placebo.

Background: The intestinal mucosa of ulcerative colitis patients expresses high levels of interleukin 34, and mice lacking IL-34 have more severe DSS-induced experimental colitis. There are no studies on the effects of directly upregulating intestinal IL-34 on experimental colitis in mice.
Methods: The bacteria EcN/CSF-1 and EcN/IL-34, which express CSF-1 and IL-34, respectively, were genetically engineered from Escherichia coli Nissle 1917 (EcN).

Introduction: The purpose of this European multicenter study was to describe and assess the characteristics, diagnosis, management, and recurrence of oral malignant melanoma at different European oral and maxillofacial surgery centers.
Materials And Methods: This study was based on a systematic computer-assisted database that allowed the recording of data for all primary oral mucosal melanomas treated in the involved surgical units across Europe between January 1, 2003 and December 31, 2022. The following data were recorded for each patient: gender, age, site, TNM staging, metastases, symptoms, imaging features, histopathological features, treatment, complications, recurrence, follow up, and survival.

Background: Ulcerative colitis (UC) is a persistent chronic, non-specific inflammatory disease, and macrophages play a crucial role in its pathogenesis. Spleen tyrosine kinase (Syk) is strongly associated with the pathogenesis of several inflammatory diseases. However, the role of Syk in the pathogenesis of UC is still obscure.

: is the leading cause of chronic gastritis, peptic ulcer, gastric adenocarcinoma, and mucosal-associated lymphoma. Due to the emerging problems with antibiotic treatment against in clinical practice, vaccination has gained more interest. Oral immunization is considered a promising approach for preventing initial colonization of this bacterium in the gastrointestinal tract, establishing a first line of defense at gastric mucosal surfaces.
