pteridium aquilinum/hemorrhage

Single subcutaneous injections of 5 and 10 mg/kg of braxin C (BC), ptaquiloside, a toxin isolated from bracken fern, have been shown to induce hemorrhagic cystitis in guinea pigs. In order to determine whether the hemorrhagic cystitis induced by BC is due to the urotoxic effects or not, BC was

OBJECTIVE To examine stands of bracken fern (Pteridium esculentum) from throughout New Zealand for the presence and concentration of ptaquiloside (Pta), and to compare the presence and/or concentrations of Pta in areas where bovine enzootic haematuria (BEH) and/or acute haemorrhagic syndrome (AHS)

Epidemiological data on Pteridium aquilinum intoxication in cattle the state of Santa Catarina were obtained by review of diagnostic records from 1987 to 2001. Of 3,407 necropsied cattle, 244 (7.16%) were diagnosed as intoxicated by Paquilinum; 122 of those were of the hemorrhagic form, 103 had

This study was conducted to elucidate the hemolytic activity of a new toxic substance in bracken fern. A crude extract (CE) was prepared from the methanol extracts of bracken by the column chromatography. When the CE was injected subcutaneously in guinea pigs, the hemoglobinuria and hemolysis were

The ubiquitous bracken fern (genus Pteridium) is the only higher plant known to cause cancer naturally in animals. In addition to the well-recognized syndromes of thiamine deficiency, acute haemorrhage associated with myeloid aplasia and blindness due to retinal degeneration, it causes neoplasia of

Braxin C (BC), ptaquiloside, is a toxin isolated from bracken fern. In order to determine the characteristics of the acute BC toxicity, BC was administered as a single subcutaneous (s. c.) injection to guinea pigs, rats, and mice. BC (5 and 10 mg/kg) induced hemorrhagic cystitis and hematuria in

An outbreak of acute febrile syndrome associated with coagulopathy and severe pancytopenia occurred in cattle grazing in paddocks with high infestation by Adiantopsis chlorophylla. The administration of the plant to a calf reproduced the same signs and lesions seen in spontaneous cases.

Polystichum squarrosum fern fed (30% w/w) rats showed moderate mortality, decrease in body weight, less body fat and splenomegaly. On post-mortem examination, significant gross lesions were not seen in sacrificed animals. Histopathologically, Polystichum fed rats showed dilated Virchow Robin's space

METHODS Data are from a multicenter, randomized, double blind clinical trial of acute spinal cord injury. OBJECTIVE To evaluate the prognostic value of magnetic resonance imaging (MRI) for randomized patients in the National Acute Spinal Cord Injury Study 3 (NASCIS). METHODS Sixteen spinal cord

OBJECTIVE With advances in neonatal care, more children born prematurely are successfully reaching school age. It is unknown how many will be ready for school and what factors affect school readiness. Our objective was to assess readiness of children born prematurely for entry into public school,

BACKGROUND Most premature infants are not sufficiently mature physiologically to take all of their required water and nutrients orally, and so they cannot regulate their own water intake. Thus, the caregiver must determine the amount of water to be given each day to such infants. OBJECTIVE The

BACKGROUND This section is under preparation and will be included in the next issue. OBJECTIVE To determine whether the design of an umbilical arterial catheter influences the frequency of ischemic events, aortic thrombosis, intraventricular hemorrhage, mortality or necrotising enterocolitis in
