Peritoneal Potassium and pH Measurement in Early Diagnosis of Acute Mesenteric Ischemia in Rats.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND In contemporary practice, acute mesenteric ischemia (AMI) remains a serious cause of morbidity and mortality in abdominal emergencies. OBJECTIVE We report the measurement of peritoneal fluid potassium and pH on a small series of rats that developed extensive AMI following the surgical

[pH value and potassium level of diagnostic peritoneal lavage fluid in the early diagnosis of acute mesenteric ischemia secondary to arterial occlusion in rats].

An 83-year-old woman was referred to our emergency department with acute urticaria and sudden shortness of breath approximately 30 min after taking rectal diclofenac potassium for lumbago. After treatment with adrenaline and corticosteroids, the patient became hemodynamically stable and left the

The effects of glucose-insulin-potassium solution and BN 52021 in intestinal ischemia-reperfusion injury.

Numai utilizatorii înregistrați pot traduce articole

The objective of this study was to investigate effects of glucose-insulin-potassium (GIK) solution and BN 52021, a platelet-activating factor antagonist, on intestinal ischemia-reperfusion injury. Fifty male Sprague-Dawley rats (200-225 g) were divided into 5 groups each containing 10 rats; group

[Metabolic response and aggression: potassium and water content of skeletal muscles].

The authors present the results of a study of the amount of water and potassium in small samples of skeletal muscle and of the intestinal wall of albino rats. Five groups of 10 animals were separated according to the following conditions: peritonitis, pyloric obstruction, intestinal obstruction,

Identification of risk factors for perioperative mortality in acute mesenteric ischemia.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Acute intestinal ischemia is in most cases a lethal condition with a low survival rate. Risk factors of perioperative mortality are poorly defined. The aim of this study was to define risk factors that predict an adverse outcome of acute mesenteric ischemia (AMI). METHODS A total of 132

Clinical outcomes and prognostic factors after surgery for non-occlusive mesenteric ischemia: a multicenter study.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND To date, no large-scale study has been undertaken to understand the clinical features of non-occlusive mesenteric ischemia (NOMI) after surgery. We thus performed a multicenter investigation to clarify the clinical outcomes and prognostic factors of NOMI. METHODS Clinical databases from

Dexfenfluramine elevates systemic blood pressure by inhibiting potassium currents in vascular smooth muscle cells.

Appetite suppressants, such as dexfenfluramine (dex), are associated with primary pulmonary hypertension, valvular heart disease, and systemic vascular complications, such as coronary, cerebral, or mesenteric ischemia. These drugs suppress appetite by enhancing release and inhibiting reuptake of

Ethyl pyruvate: a novel anti-inflammatory agent.

Pyruvate plays a central role in intermediary metabolism. Pyruvate, however, is also a potent antioxidant and free radical scavenger, and numerous studies have shown that treatment with this compound can be salutary in numerous pathologic conditions that are thought to be mediated, at least in part,
