Additional evidence is presented affirming the role of the intestinal pool of endotoxin in producing irreversibility in prolonged hemorrhagic shock. The fact that coliform-free rabbits tolerate exposure to a degree and duration of hemorrhagic shock which is lethal for rabbits that possess the normal flora, and that these tolerant rabbits lose their tolerance when E. coli are introduced into the...

T here is considerable public, media, and scientific interest in ‘‘natural’’ products, including probiotics, in modulating intestinal inflammation and health. Intestinal microflora are intimately involved in the generation of immunocompetent cells and tuning the balance between T helper 1 (Th1) and Th2 immunity during the development of the gut associated immune system. It is now generally acce...

From numerous studies during the last years it became evident that bacteria and bacterial constituents play a decisive role both in the maintenance of intestinal immune homeostasis as well as in the development and perpetuation of chronic intestinal inflammation. In this review we focus on the role of bacterial DNA which is a potent immunomodulatory component of the bacterial flora. Bacterial D...

Graft-versus-host disease (GHVD) is a severe complication after allogeneic hematopoietic stem cell transplantation. The degree of inflammation in the gastrointestinal tract, a major GVHD target organ, correlates with the disease severity. Intestinal inflammation is initiated by epithelial damage caused by pre-conditioning irradiation. In combination with damages caused by donor-derived T cells,...

Crohn's disease (CD) is a chronic, relapsing inflammatory disorder that can occur anywhere along the gastrointestinal tract. The precise etiology of CD is still unclear but it is widely accepted that a complex series of interactions between susceptibility genes, the immune system and environmental factors are implicated in the onset and perpetuation of the disease. Increasing evidence from expe...

INTRODUCTION Bowel-associated dermatosis-arthritis syndrome is rare systemic diseases characterized by a prodrome of fever, chills, and influenza-like symptoms with subsequent skin eruptions, myalgias, and polyarthralgias. It is reported to be occurred in Intestinal bypass surgery and inflammatory bowel disease. CASE DESCRIPTION Herein, we described a 29-years-old man with Bowel-associated de...
