A 68-year-old man died 18 days after the onset of ischemic optic neuropathy caused by histologically proven giant-cell arteritis. On histopathologic study of the eye, ischemic necrosis of the prelaminar and retrolaminar optic nerve was seen, along with the massive presence of acid
A single (100 mg/kg) intraperitoneal dose of 2-bromoethanamine hydrobromide induced renal papillary necrosis (RPN) acutely in rodents and caused a transient crystalluria between 4 and 8 h after dosing. These crystals comprised struvite or magnesium ammonium phosphate (MAP) as assessed by shape,
Although valvular lesions are rare in acromegaly, two patients with click-murmur syndrome and one patient with aortic insufficiency secondary to myxomatous degeneration and cystic medial necrosis of the aorta have been reported. Growth hormone excess has been postulated to potentiate these
BACKGROUND
The major causes of in-flight fatal incapacitation in civil pilots are acute coronary events, new onset idiopathic epilepsy, and physiological problems. Less than 1% of all air accidents are due to sudden incapacitaion. The problem with acute coronary disease is very serious when
Morphological changes were followed in semi-thin glycolmethacrylate sections, after treating male Wistar rats with a single ip dose of 2-bromoethanamine (BEA) hydrobromide (100 mg/kg) to induce renal papillary necrosis. Medullary interstitial cells had irregular nuclei at 4 hr and focal necrosis by
BACKGROUND
A biofilm is defined as a collection of organisms attached to a surface and surrounded by a matrix.
OBJECTIVE
To present three cases in which bowel necrosis coexisted with biofilm.
METHODS
The medical records, bacteriological findings and tissue biopsies from three infants with bowel
Review of experimental work indicates that renal papillary necrosis (RPN) is more readily induced by mixtures of analgesics which include phenacetin or paracetamol, than by either of the latter drugs alone. In an experiment in which moderate doses of analgesics were given to rats over a long period,
Severe essential hypertension in a subset of American black subjects is associated with marked stenosis of interlobular arteries and arterioles of the kidneys, observed by renal biopsy and binephrectomy specimens. The interlobular arterial stenosis is caused by marked thickening of the intima due
We have evaluated the potential of urinary uronic acid measurement as an early indicator in the development of renal papillary necrosis (RPN). Urinary uronic acid was quantified with a range of other urinary biochemical parameters in rats given multiple doses of N-phenylanthranilic acid (NPAA) or
Yam (Dioscorea batatas) mucopolysaccharide (YMP) was examined for the ability to induce secretory and cellular responses in murine peritoneal macrophages. When macrophages were treated with various doses (10-100 microg/ml) of YMP for 48 h, a significant cytotoxicity against B 16 cells was observed.
A polysaccharide storage myopathy is described in nine Quarterhorses, Quarterhorse crossbreds, American Paints and Appaloosa horses which had a history of recurrent exertional rhabdomyolysis. Muscle biopsies were characterized by high muscle glycogen concentrations with up to 5% of type 2 muscle
Three days after herpes simplex virus inoculation, an increased amount of DNA and RNA was observed in the superficial epithelium cells of rabbit cornea. Histochemical staining demonstrated the development of acid mucopolysaccharides and the destruction of reticulin. In the early stages, on rare
