The neutrophil and macrophage responses that accompany inflammation were studied in the peritoneal cavity of rainbow trout Oncorhynchus mykiss using light and electron microscopic cytochemistry. Neutrophils of inflammatory peritoneal exudates were alpha-naphthyl butyrate esterase-negative, peroxidase-positive and rich in cytoplasmic glycogen granules. Macrophages were poor in glycogen, esterase...

For in vivo cell implantation techniques to be successful, the energy and metabolic substrate requirement of the cells being grown must be met. Certain cells with high-energy requirements (e.g., hepatocytes, pancreatic island cells) experience a high degree of cell death after implantation due to a limited supply of oxygen. We proposed that the pleural cavity might be an oxygen-rich environment...

Abstract The pleural and peritoneal cavity share many related features due to their common celomic origin. Normally these two spaces are completely separated with the development of diaphragm. Defects in diaphragm morphogenesis may result congenital diaphragmatic hernias, which is most known form communication between cavity. However, several cases, findings pleuroperitoneal (PPC) have been des...

conclusions: the study findings revealed that peritoneal lavage with imipenem solution (1 mg/ml) decreases the rate of post-operative ssis in patients with perforated appendicitis in comparison to patients irrigated with normal saline alone. these patients also had shorter hospital stay, and lower hospital costs. results: imipenem solution irrigation was associated with significant clinical imp...

STK, a new member of the hepatocyte growth factor receptor family, is the receptor for macrophage-stimulating protein (MSP), which acts on murine resident peritoneal macrophages. We established polyclonal and monoclonal antibodies against STK and characterized the structure of STK protein and STK expression on cells of the mononuclear phagocyte system. Western blotting showed that the STK trans...

Background: Peritoneal metastases (PM) are a common manifestation of gastro-intestinal and gynecological cancers. Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) has been proposed as new drug delivery technique to treat patients with PM. During this procedure, CO2 pneumoperitoneum (12 mmHg) is established. Subsequently, nebulizer (Capnopen®, Zimmern, Germany) aerosolizes the chemothera...

Peritoneal sarcomatosis/carcinomatosis is a rare observation in pediatric practice. It occurs, as rule, with various sarcomas, sarcomatoid tumors, desmoplastic small round cell tumors. Cytoreductive surgery followed by abdominal chemoperfusion has established itself an effective method of treating such conditions adult practice and gaining popularity Laparoscopic cytoreduction hyperthermic used...

BACKGROUND CD40 has been identified on a variety of cell types, and it plays an important role in adaptive immunity and inflammation. Peritoneal mesothelial cells (PMCs) are the main cell layer that line the peritoneal membrane. Previously we found that CD40 ligand (CD154) is functionally expressed on peritoneal macrophages during continuous ambulatory peritoneal dialysis peritonitis. However, ...

A precise diagnosis of peritoneal dissemination is necessary to determine the appropriate treatment strategy for colorectal cancer. However, small peritoneal dissemination is difficult to diagnose. 5-aminolevulinic acid (5-ALA) is an intermediate substrate of heme metabolism. The administration of 5-ALA to cancer patients results in tumor-specific accumulation of protoporphyrin IX (PpIX), which...

BACKGROUND The prevention and restoration of peritoneal damage is a critical mission in peritoneal dialysis (PD). Transplantation of mesothelial cells has been suggested to suppress peritoneal injury during PD. Few studies have examined the efficacy and safety of cell transplantation. We evaluated the paracrine effects of mesothelial transplantation during peritoneal repair using immortalized t...
