Postoperative bowel obstruction caused by intra-abdominal adhesions occurs after all types of abdominal surgery. It has been suggested that the laparoscopic technique should reduce the risk for adhesion formation and thus for postoperative bowel obstruction. This study was designed to compare the incidence of bowel obstruction in a randomized trial where(More)
OBJECTIVE To examine the effects of the PROACT treatment on the fibrinolytic system and inflammatory cytokines in human peritoneum. DESIGN Controlled clinical study. SETTING University hospital. PATIENT(S) Nine subjects undergoing laparotomy had peritoneal samples taken at the incision. INTERVENTION(S) The PROACT applicator was inserted through the(More)
The purpose of this study was to compare the levels of procollagen type I messenger RNA (mRNA) in normal and healing medial collateral ligament (MCL) and anterior cruciate ligament (ACL) in a rabbit model. Our method of injury involved a surgical model with identical partial lacerations in the midsubstance of the MCL and ACL. Paraffin sections of normal(More)
Degradation of the extracellular matrix plays an important part during the invasion of cancer cells into the surrounding tissue. The matrix metalloproteinases (MMPs) have a central role in this process as demonstrated in different malignancies. The aim of this study was to investigate the presence of several MMPs from tumour, adjacent tumour-free colon(More)
INTRODUCTION There is evidence that TGF-beta 1 plays a role as a tumor suppressor in early disease and has pro-oncogenic effects in advanced tumor stage. The aim of the study was to correlate TGF-beta 1 in plasma and tissue to clinical and pathological parameters in patients with various stages of disease progression. METHODS One hundred sixty-nine(More)
BACKGROUND It is well known that the fibrinolytic system is of importance in inflammation, wound healing, and fibrosis development. However, it is also important in the process of tumor invasion and metastasis. We have investigated protein levels of urokinase plasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1) in rectal cancer and(More)
Matrix metalloproteinases (MMPs) and the tissue inhibitors of MMPs (TIMPs) have been demonstrated to be involved in inflammatory conditions in the intestine. The purpose of this study was to investigate whether the alterations of the MMP/TIMP balance might reflect the course of the inflammatory process in acute appendicitis and if the expression and(More)
Overexpression of matrix metalloproteinases (MMPs) has been observed in chronic, compared to acute, wounds and altered levels might impair healing. During treatment of wounds, examination gloves are routinely used, and the wound environment thus gets exposed to gloves. The aim of this study was to characterize secretion of MMPs and tissue inhibitors of(More)
In rectal cancer treatment, preoperative radiotherapy has led to reduction of local recurrence, but it is associated with morbidity and increased risk for secondary tumours. Matrix metalloproteinases (MMPs) are associated with tumour progression through tissue remodeling. The aim of this study was to investigate tissue remodeling after preoperative(More)
OBJECTIVE Complicated diverticular disease is associated with extensive structural changes of the colonic wall. Turnover of extracellular matrix (ECM) plays a pivotal role in this process. Proteolytic enzymes, including matrix metalloproteinases (MMPs), are capable of degrading most components of ECM. Their activity is regulated by inhibitors, tissue(More)
