Background: This study aimed to evaluate the healing effects of adipose tissue-derived mesenchymal stem cells (AT-MSC) and sildenafil citrate alone or in combination of colon anastomosis experimental model.

Methods: A total of 40 female Wistar rats were randomly distributed to four groups: Control (without any intervention post-anas-tomosis), stem cell (AT-MSC injection on the anastomosis site), SIL (oral gavage of 10 mg/kg sildenafil citrate), and stem cell + SIL (AT-MSC injection and oral administration of sildenafil citrate) groups. Rats were euthanized 5 days post-anastomosis.

Background: The objective of the current study was to investigate the value of the ischemic biomarkers endothelial cell-specific molecule-1 (endocan) and signal peptide-CUB-EGF domain-containing protein-1 (SCUBE-1) in the diagnosis and assessment of earlystage and irreversible damage in acute mesenteric ischemia.

Methods: An experimental mesenteric ischemia reperfusion model was designed using 54 rats. Nine groups were created: Three sham groups [Groups I (30th minute), IV (2nd hour), and VII (6th hour)], in which only blood and tissue specimens were sampled; 3 ischemia groups [Groups II (30th minute), V (2nd hour), and VIII (6th hour)], in which blood and tissue specimens were sampled after ligation of the superior mesenteric artery (SMA); and 3 reperfusion groups [Groups III (30th minute), VI (2nd hour), and IX (6th hour)], in which blood and tissue specimens were sampled after declamping the SMA and reperfusion for 1 hour.

The aim of the study is to describe the cognition of breast cancer with respect to knowledge, beliefs, attitudes and behavior in a group of gestational age Turkish women. A questionnaire survey was therefore performed on 201 randomly selected women registered to the health database in Aydin. In age, marital status, and occupation were found to significantly impact on breast self-examination (BSE) performance, which should still be considered as an important tool for early diagnosis, although it does not substitute clinical examination and education.

Background: C-reactive protein (CRP) is used as a marker of intestinal ischaemia. This study evaluated whether CRP levels can be used to detect ischaemia-induced (strangulated) intestinal obstruction and subsequent bacterial translocation.

Methods: Forty-eight rats, divided into four groups underwent the following procedures: anaesthesia alone (native controls), laparotomy (sham-operated controls), or surgical induction of simple or strangulated intestinal obstruction (simple and strangulated obstruction groups, respectively).

Background/aims: The role of nitric oxide (NO) in bacterial translocation (BT) associated with acute pancreatitis is controversial. We investigated the effects of the NO synthase substrate, L-arginine, and the NO synthase inhibitor, N-nitro-L-arginine methyl ester (L-NAME), on BT in caerulein-induced acute pancreatitis in rats.

Methods: Acute pancreatitis was induced by subcutaneous injections of caerulein (12 microg/kg) at 6-hour intervals for 2 days.

Background: Previous reports of recurrent intra-abdominal abcess formation after the laparoscopic treatment of perforated acute appendicitis led us to investigate the possible effects of gas insufflation on the spread of infection. We previously showed that Escherichia coli counts were significantly higher in a laparoscopy group that underwent carbon dioxide (CO2) insufflation than in control and laparotomy groups. The aim of this study is to investigate the effects of intra-abdominal CO2 and nitrous oxide (N2O) insufflation on anaerobic bacterial growth in a rat model.

This study was performed to describe a new model of strangulation obstruction mimicking the situations relevant to abdominal hernias. The strangulation obstruction was induced either by intra-abdominal ligation of an ileal segment 2 cm in length (n = 20) or by a pursestring suture around a fascial defect with a strangulated intestinal loop placed subcutaneously (n = 20). Ten animals served as sham operated controls (n = 10).

Behcet' s Disease (BD ) is a complex multisystemic disease, which is characterized by recurrent oral and genital aphteous ulcers and iritis in which vasculitis can also be one of the possible clinical manifestations. A thirty seven year-old female patient with incomplete BD was admitted to emergency service, with intra-abdominal hemorrhage more severe than that would be expected, with the degree of related trauma. We decided to manage the patient conservatively, observing vital signs, haemogram, computed tomography (CT) and angiography instead.
