hernial sac or subcutaneous tissue would consistently demonstrate signs of colic, this does not occur in most cases of strangulating umbilical hernias. Horses with intestinal incarceration within an umbilical hernia can have several different clinical presentations. The most common is a reducible umbilical hernia in a young horse (i.e., usually 6 to 12 months of age) that develops acute abdomin...

OBJECTIVE To examine the efficacy of psyllium mucilloid in evacuating sand from the equine large intestine. ANIMALS 12 clinically healthy pony geldings. PROCEDURE Twelve ponies were assigned to 2 groups of six each. One group was treated with psyllium and the second was a control group. All ponies had an exploratory celiotomy and 10 g/kg body weight of sand was placed into the cecum. Ponies...

Patients with primary, recurrent, or metastatic colorectal adenocarcinoma were given injections of 200 micrograms of anticarcinoembryonic antigen (CEA) monoclonal antibody labeled with 2 mCi of 111In (Indacea). Patients were imaged at 24 and 48 h. Celiotomy was performed on 40 patients between 3 and 17 days post-Indacea injection. Of 16 primary tumors, 11 (69%) were imaged. Of six extrahepatic ...

BACKGROUND Ventral midline hernia formation following abdominal surgery in horses is an uncommon complication; however, it can have serious consequences leading to increased morbidity and mortality. Currently, mesh hernioplasty is the treatment of choice for large ventral midline hernias in horses to allow potential return to normal function. Complications following mesh hernioplasty using poly...

BACKGROUND Celiotomy is the most common approach for refractory small bowel obstruction (SBO). Small reviews suggest that a laparoscopic approach is associated with shorter stay and less morbidity. Given the limitations of previous studies, we sought to evaluate outcomes of laparoscopic (L) compared with open (O) adhesiolysis for SBO, using the National Surgical Quality Improvement Program data...

BACKGROUND Lactated ringers (LR) and normal saline (NS) are used interchangeably in many trauma centers. The purpose of this study was to compare the effects of LR and NS on coagulation in an uncontrolled hemorrhagic swine model. We hypothesized resuscitation with LR would produce hypercoagulability. METHODS There were 20 anesthetized swine (35 +/- 3 kg) that underwent central venous and arte...

background & target: ischemia reperfusion injury is the tissue damage caused when blood supply returns to the tissue after a period of ischemia or lack of oxygen. in this study, the effect of pentoxyfylline on bcl2 gene expression changes and cell injury in kidney of rat following ischemia reperfusion were evaluated.methods: in this experimental study, 20 male wistar rats with average weight of...

global cerebral ischemia (gci) and reperfusion induced apoptosis that lead to cell injury and death. the bax and bcl-2 are pro-apoptotic and anti-apoptotic genes, respectively. these genes belong to the b-cell lymphoma-2 (bcl-2) family.in this study; we assessed the effect of pentoxifylline drug on bax/bcl2 gene dosage expression changes following   ischemic reperfusion injury in kidney. in thi...

HYPOTHESIS Metastatic melanoma to the liver is not incurable; complete surgical resection can achieve long-term survival in selected patients. BACKGROUND Metastases to the liver are diagnosed in 10% to 20% of patients with American Joint Committee on Cancer stage IV melanoma. Surgical resection has not been generally accepted as a therapeutic option, as most patients will have other sites of ...

OBJECTIVE Thyroid hormones affect gastric acid secretion. As the mechanism of this effect has not been fully known, in this experimental study the isolated gastric acid secretion of hypothyroid and hyperthyroid rats were compared with control group by the administration of different doses of pentagastrin, histamine and carbachol as gastric acid secretion stimulators. METHODS This study was ca...
