The events responsible for cell injury after a tissue stimulation are only incompletely understood. The purpose of this study was to examine mechanisms of cell injury in two tissues, rat mesentery and cremaster muscle, after tissue stimulation with N-formylmethionyl-leucyl-phenylalanine (FMLP) and platelet-activating factor (PAF). The response was studied in the same animal in random order usin...

Mesenteric panniculitis is a rare condition of unknown etiology that causes inflammation of the adipose tissue in the mesentery. We describe a case in which mesenteric panniculitis was diagnosed on the basis of imaging and resolved spontaneously.

The use of inferior vena cava (IVC) filters has been increasingly prevalent. Although they are relatively safe with clear indications, not without complications. Late-onset complications include IVC filter migration, wire fracture, strut penetration, and perforation organs in its vicinity. In this report, we present the case a patient small bowel volvulus secondary to an causing tethering mesen...

Solitary fibrous tumors (SFTs) represent an uncommon entity most frequently manifested in the pleura. We describe herein two new cases located in the jejunal and sigmoid mesentery incidentally found in patients aged 61 and 32 years. In a review of the literature, we have compiled 15 mesenteric SFTs including our two cases. The mean age of the patients at presentation was 51.7 years (range, 26-8...

A 64-year-old woman was admitted to our hospital with lower abdominal pain. Routine laboratory values were unremarkable except for the white blood cell count (15,000/micro litter) and the C-reactive protein (CRP) value (22.5 mg/dl). A Computed tomography (CT) scan revealed air collection in the middle of the anterior pararenal space. One day later, CT revealed air collection in the anterior par...

One hundred specimens of unicorn leatherjacket, Aluterus monoceros purchased from markets of municipalities of Niterói and Rio de Janeiro from May to August 2006. The fishes were measured, necropsied, fileted and analysed their organs. Sixteen fishes were parasitized by nematode Anisakidae: Anisakis spp. and Contracaecum sp. with respectively, 1 and 16% of prevalence, 2 and 3.31 of mean intensi...

Previous morphological studies revealed that the adipose tissue is innervated by adrenergic nerve fibers. Furthermore, physiological studies showed that the metabolism of adipose tissue is controlled by the adrenergic component of the nervous system. However, nothing is known on the sources of innervation of different fat tissue depots. Therefore, we decided to study the distribution of ganglio...

An unusual case of a jejunal mesenteric pseudocyst treated by laparoscopic resection is reported. A 44-year-old woman was admitted to our hospital with intermittent upper abdominal pain and diarrhea. Physical examination revealed slight periumbilical tenderness, and no masses were palpable. Contrast-enhanced computed tomography showed a 4-cm-sized nonenhancing high-density mass with a heterogen...

BACKGROUND Tumors involving the root of the mesentery are generally regarded as "unresectable" with conventional surgical techniques. Resection with conventional surgery may end in life-threatening complications in these patients. Ex-vivo resection and auto-transplantation avoids excessive bleeding and prevents ischemic related damage to the small intestine and other organs. OBJECTIVE To shar...

Hind guts of 9i-day mouse embryos were transplanted into the posterior part of the coelomic cavity of 2|-day chick embryos. The hosts were sacrificed after 1-7 days and the mouse primordial germ cells (PGCs) in the graft and in the surrounding host tissues were searched for by means of the histochemical technique for alkaline phosphatase. Altogether 94 grafts were examined. During the first 3 d...
