The Effect of Mycophenolate Mofetil on Early Wound Healing in a Rodent Model.

Background: Immunosuppressant agents are inevitable for solid organ recipients, but may have a negative effect on wound healing that is difficult to measure because of clinical use of a polydrug regime. The evidence on mycophenolate mofetil (MMF) is scarce and contradictory. This study aims to investigate the effect of MMF administration on wound healing.

The effect of fibrin glue on the early healing phase of intestinal anastomoses in the rat.

Purpose: Protecting the anastomotic integrity using suture or staple line reinforcement remains an important goal for ongoing research. The present comprehensive study aims to establish the effects of fibrin glue on the early phase of anastomotic healing in the rat intestine.

Methods: One hundred and eight young adult male Wistar rats underwent resection and anastomosis of both the ileum and colon.

Everolimus-induced loss of wound strength can be prevented by a short postoperative delay in its administration.

The use of mammalian target of rapamycin inhibitors coincides with an increased incidence of surgical complications. In previous experiments, serious negative effects of postoperative everolimus on anastomotic strength were found. This study aims to investigate if delayed drug administration can prevent loss of wound strength.

Peritoneal cytokines predict mortality after surgical treatment of secondary peritonitis in the rat.

Background: The study aimed to analyze if peritoneal cytokine levels can predict survival in an experimental model for peritonitis. Early identification of patients most at risk for adverse outcomes would facilitate the decision for aggressive therapy in order to maximally exploit their chance for survival.

Study Design: Peritonitis was induced by intraperitoneal injection of a feces/bacteria mixture in 175 rats.

Persistent effects of everolimus on strength of experimental wounds in intestine and fascia.

The introduction of mTOR-inhibitors in transplantation surgery has been associated with an increase in wound complications. We have previously reported a massive negative effect of everolimus on anastomotic strength in rat intestine at 7 days postoperatively. Because it is clinically important to know if this effect persists and occurs generally, repair in both intestine and abdominal wall has been investigated over a period of 4 weeks.

Reduction of oxygenation and blood flow in pedicled bowel segments in the rat and its consequences for anastomotic healing.

Purpose: Experimental studies indicate that perioperative hypoperfusion impairs anastomotic healing. In bowel surgery, the part of bowel that will be anastomosed is often pedicled, leaving the blood supply dependent on the marginal artery only. Little is known about the blood supply in such a segment, and whether anastomotic strength is affected when flow would be reduced.

Tissue-type plasminogen activator prevents abscess formation but does not affect healing of bowel anastomoses and laparotomy wounds in rats with secondary peritonitis.

Background: Intra-abdominal application of recombinant tissue-type plasminogen activator (rtPA) can decrease the rate of abscess formation in a rat peritonitis model. Before using rtPA clinically, its effects on healing of bowel anastomoses and laparotomy wounds should be investigated.

Methods: Peritonitis was induced in 148 male Wistar rats via intra-abdominal injection of a feces/bacteria mixture.

Intercellular adhesion molecule-1 and gelatinase expression in human peritoneal mesothelial cells during propagation in culture.

Mesothelial cells are involved in a variety of biological processes, which include the formation of peritoneal adhesions. The cultures of human peritoneal mesothelial cells comprise an important tool to investigate the behavior and functions of mesothelial cells. Very little is known about the differences among mesothelial cells isolated from different sources and about the changes in specific functions as caused by cell propagation in vitro or that result from storage of cells at low temperatures.

Everolimus interferes with healing of experimental intestinal anastomoses.

Background: Although clinical data suggest its existence, little is known about the effect of rapamycin derivatives on wound repair. This study aims to delineate the influence of the mammalian target of rapamycin inhibitor everolimus on wound healing in the rat intestine.

Methods: Four groups of 26 male Wistar rats received everolimus in daily oral dosages of 0 (controls), 0.

Doxycycline improves wound strength after intestinal anastomosis in the rat.

Background: The strength of intestinal anastomoses is relatively low in the first days after operation, possibly as a result of localized degradation of the supporting matrix by enzymes from the matrix metalloproteinase (MMP) family. The aim of this study was to examine whether doxycycline, a drug known to inhibit MMP activity, could enhance anastomotic strength.

Methods: Male Wistar rats received anastomoses in both ileum and colon.

Intestinal anastomoses from diabetic rats contain supranormal levels of gelatinase activity.

Purpose: Early postoperative strength in intestinal anastomoses is reduced in diabetic rats, whereas collagen deposition is essentially unchanged, suggesting that increased matrix degradation may be the cause of diminished wound strength. The aim of this study was to investigate whether (gelatin-degrading) matrix metalloproteinase activity is enhanced in intestinal anastomoses from diabetic rats.

Methods: Sixty male young adult Wistar rats underwent resection and anastomosis of both ileum and colon.
