background: in recent years, immunocompromised patients are at high risk for the development of invasive aspergillosis. due to the increase of antimicrobial resistance, natural agents with medicinal and immunomodulatory effects has gained more attention. honey is a natural substance with documented antimicrobial, anti-inflamatory and wound healing effects. objectives: the purpose of this study ...

Background: Chemokines, proteins that operate within the body's immune system, play numerous roles in menstruation, bacterial infection, implantation of embryos, and the maintenance of early pregnancy. They are also strongly related to the pathogenesis of endometriosis. Materials and Methods: This is review article that were indentifical by computer search of MEDLINE (1984- 2013). Results:...

The profile of arachidonic acid metabolites in resident peritoneal macrophages is distinctly different from the profile of macrophages isolated after an acute bacterial infection. The latter produce decreased prostaglandins E2 and I2 and leukotriene C4 while conserving the synthesis of thromboxane A2. We show here that the initial changes in peritoneal macrophage arachidonate metabolism during ...

High levels of plasminogen activator (PA) were induced in mouse peritoneal macrophages by infection with BCG, 2-6 X 10(7) viable organisms intravenously, followed 3-4 wk later by intraperitoneal challenge with purified protein derivative (PPD) 2 days before harvest. Macrophages obtained from infected animal without boosting showed little fibrinolytic activity, but challenge of Bacille-Calmette-...

A mouse-specific macrophage antigen (MSMA) was identified in NP-40 extracts of 125I-radiolabeled mouse preitoneal macrophages by using a rabbit anti-mouse macrophage serum (AMS) and SDS-polyacrylamide gel electrophoresis. The antigen was shown to have a m.w. of 83,000 daltons and was present on both normal and "activated" peritoneal macrophages. MSMA was also present on syngeneic adherent splee...

In an effort to better understand genetic and cellular factors that influence innate immunity, we examined host and bacterial factors involved in the nonopsonic phagocytosis and killing of Escherichia coli K-12 by mouse macrophages. Unelicited (resident) peritoneal macrophages from five different mouse strains, BALB/c, C57BL/6, CD-1, C3H/HeJ, and C3H/HeN, were employed. Additional macrophage po...

We demonstrate that glycoprotein isolated from Dioscorea batatas (GDB) activates macrophage function. Analysis of the infiltration of macrophages into peritoneal cavity showed GDB treatment significantly increased the recruitment of macrophages into the peritoneal cavity. In order to further confirm and investigate the mechanism of GDB on macrophage activation, we analyzed the effects of GDB on...

OBJECTIVE To further investigate peritoneal iron disruption in endometriosis by studying iron storage in peritoneal macrophages of patients with endometriosis compared with controls. DESIGN Cross-sectional study. SETTING Academic gynecology research unit in a university hospital. PATIENT(S) Fifty patients undergoing laparoscopy. INTERVENTION(S) Collection of peritoneal fluid samples (N ...

Extravascular coagulation leading to fibrin deposition accompanies many immune and inflammatory responses. Although recognized by pathologists for decades, and probably pathologic under certain conditions, the physiologic functions of extravascular coagulation remain to be fully defined. This study demonstrates that thrombin can activate macrophage adhesion and prompt interleukin-6 (IL-6) and m...

Infections are an important cause of morbidity and mortality in patients with decompensated cirrhosis and ascites. Hypothesizing that innate immune dysfunction contributes to susceptibility to infection, we assessed ascitic fluid macrophage phenotype and function. The expression of complement receptor of the immunoglobulin superfamily (CRIg) and CCR2 defined two phenotypically and functionally ...
