Acute mesenteric ischemia (AMI) is an abdominal-vascular emergency which is rare and has high mortality rates (60-80 %) due to late diagnosis (1-3). Although it is known that extravascular reasons like intestinal intussusception, volvulus, strangulated hernias and obstructions can cause intestinal gangrene, these are rarely the cause of AMI (1). ⋯ As a result, in rats with SMA occlusion serum D-dimer levels were not increased significantly when compared either in the group or with the basal values of the control group and values in operative control group. Therefore, it is concluded that D-dimer is not a useful marker for early diagnosis of AMI. On the other hand, it is revealed that blood L-lactate levels began to increase significantly following 4th hour of mesenteric ischemia and it is shown that this increase continued at the 6th hour. In addition, considering the utmost importance of the early diagnosis in patients with the clinical suspicion of AMI, L-lactate seems to be a suitable marker to use in emergency departments because it is achieved with a portable device that gives fast and accurate results. Nevertheless, our results are need to be supported by clinical studies with larger patient series (Tab. 2, Fig. 11, Ref. 39).

We aimed to compare the effects of three different supraglottic airway devices, the classic LMA, PLA, and V-gel, on hemodynamics and QTc in rabbits under general anesthesia. ⋯ When comparing hemodynamic responses to other supraglottic airway devices, the response to V-gel rabbit is minimal and we consider that similar studies using the I-gel on humans are required (Fig. 5, Ref. 31).

Determine the prevalence and distribution of gastric intestinal metaplasia (GIM) in a large cohort of patients subjected to esophagogastroscopy (EGD). Evaluate usefulness of grading the severity of gastritis, GIM and the impact of Helicobacter pylori (HP). Define the population at risk for gastric adenocarcinoma (GC) and assess the value of surveillance. ⋯ Prevalence of GC in patients with GIM was more than 200 times higher than reported in normal population. Age more than 70 years and African Americans appeared to be at higher risk. Routine EGD and histological diagnosis, with simple grading of severity of epithelial changes provides a useful predictive information. Individuals with upper GI symptoms undergoing EGD with gastric biopsy benefited from routine clinical screening for GC. Patients with higher severity of GIM should enter surveillance (Tab. 1, Fig. 10, Ref. 45).

In the present study we aimed to determine the effect of an AT-II antagonist candesartan on pancreatic microcirculation in an experimental model of acute necrotizing pancreatitis. ⋯ Treatment with candesartan in the early phases of acute necrotizing pancreatitis effective on microcirculation of pancreatic tissue (Tab. 3, Fig. 6, Ref. 28).

This experimental study compared the hemostatic effects of calcium alginate and Anka-ferd Blood Stopper in hepatic parenchymal bleedings. ⋯ With this study, we demonstrated that both calcium alginate and Ankaferd have hemostatic effect in preventing hepatic parenchymal bleeding and that calcium alginate causes fibrosis in the liver, where ABS causes focal necrosis areas(Tab. 2, Fig. 4, Ref. 19).
