The peritoneal mesothelium exhibits a high regenerative ability. Peritoneal regeneration is concomitant with the appearance, in the coelomic cavity, of a free-floating population of cells whose origin and functions are still under discussion. We have isolated and characterized this cell population and we have studied the process of mesothelial regeneration through flow cytometry and confocal mi...

We here document discovery of a new and simple model of tumor seeding involving the mouse peritoneum. Irradiated tumor cells administered by i.p. injection provided effective vaccination against peritoneal carcinomatosis and distal metastasis with colorectal carcinomas. In flow cytometric analysis, CD4 and CD8+ T lymphocytes, macrophages and myeloid-derived suppressor cells (MDSCs), which are e...

Macrophages, phagocytic cells involved in an early phase of host defense, are known to express the P-selectin ligand, PSGL-1. Heretofore, P-selectin has only been found on platelets and endothelial cells. Here, we demonstrate that peritoneal macrophages isolated by peritoneal lavage of unchallenged mice express P-selectin on the plasma membrane. The peritoneal macrophages synthesize P-selectin,...

Purpose: to develop a new method of lavage the abdominal cavity in experimental conditions.Materials and methods. In experiment we use 40 rats Wistar line weighing 160-240 g, kept vivarium compliance with all standards.Research results their discussion. During relaparotomy, performed mechanical cleaning from fecal masses, layers fibrin, was washed twice 100 ml 0.02% decamethoxine solution at te...

BACKGROUND The D-mannose binding lectin ArtinM is known to recruit neutrophils, to degranulate mast cells and may have potential therapeutic applications. However, the effect of ArtinM on mast cell recruitment has not been investigated. METHODOLOGY Male Wistar rats were injected i.p. with ArtinM or ConA (control). The ability of the lectin to degranulate peritoneal and mesenteric mast cells w...

OBJECTIVES The purpose of this study holds, for the first time, an evaluation of the intraperitoneal curcumin lavage on the development of post-operative intra-abdominal adhesions. MATERIALS AND METHODS Thirty male Wistar rats were randomized into five groups. The rats were administered anesthesia and underwent surgery in order to create intra-abdominal adhesions. Before the abdomen was close...

Severe stages of acute, colonic diverticulitis can progress into intestinal perforations with peritonitis. In such cases, urgent treatment is needed, and Hartmann's procedure is the standard treatment for cases with fecal peritonitis. Peritoneal lavage may be an alternative to resection for acute diverticulitis with purulent peritonitis, but ongoing randomized trials are awaited to clarify this.
