Association between endoscopic findings and histopathological confirmation in p...

Background – The diagnosis of eosinophilic esophagitis (EoE) is performed by the detection of 15 or more eosinophils per field in an esophageal biopsy sample, but the endoscopic findings alone are not validated for a diagnosis of the disease. Objective – To evaluate the association between the endoscopic findings and histopathological diagnosis in patients with suspected EoE in endoscopy. Methods – A retrospect...

Role of regulatory T cells in irinotecan-induced intestinal mucositis

Intestinal mucositis (IM) is a common side effect of irinotecan-based chemotherapy. The involvement of inflammatory mediators, such as TNF-α, IL1-β, IL-18 and IL-33, has been demonstrated. However, the role of adaptive immune system cells, whose activation is partially regulated by these cytokines, is yet unknown. Thus, we investigated the role of regulatory T cells (Tregs) in irinotecan-induced IM. C57BL/6 mic...

BACKGROUND - Gastric polyps are elevated mucosal lesions. Most of them are less than 1 cm and when larger than 2 cm, has a high malignancy probability. The histopathological types are mainly fundic gland polyps, hyperplastic polyps and adenomatous polyps.

Dual effect of silymarin on experimental non-alcoholic steatohepatitis induced ...

Irinotecan-based regimens are commonly used for treatment of colorectal cancer, which is limited by mucositis and non-alcoholic steatohepatitis (NASH). Silymarin (SIL) prevents fatty liver disease in the clinical setting and in models of liver damage induced chemically. This study investigated the possible effect of SIL on irinotecan (IRI)-induced NASH. Swiss female mice were injected with saline (SAL 5 ml/kg i...
