(1) On the one hand was the condition found in many parts of the world of bovine enzootic haematuria with uncertain aetiology and, on the other, the investigations conducted on the acute radiomimetic cattle bracken poisoning under laboratory conditions.
(2) Mammary cancer was also induced in Sprague-Dawley rats fed a bracken diet.
(3) Inbred strain ACI rats of both sexes were divided into 4 groups; Group 1 received a diet containing the unprocessed bracken dried at a room temperature of below 30 degrees, Group 2 received a diet containing bracken dried at 70 approximately 90 degrees with a hot, forced draft, and Group 3 received the diet containing processed bracken that had been minced to a paste-like consistency using a mechanical chopper.
(4) Two glucosides to enhance histamine release from rat peritoneal mast cells were isolated from rhizomes of bracken fern (Pteridium aquilinum (L.) Kuhn) by column chromatography on Sephadex LH-20 and droplet counter-current chromatography, and named braxin A1 and A2.
(5) Powdered bracken fern mixed with a basic commercial diet (1:4 by weight) was fed to a group of 40 ICR strain mice for 20 weeks after the implantation of a glass bead into the bladder.
(6) Ten of the 13 species that depend on specific habitats - heathland, coppices, woodland glades, bracken, hedgerows and so on - have fared better on sites where farmers had agreed to tend the landscape with wildlife in mind.
(7) Thirteen cows maintained on natural bracken fern (Pteridium aquilinum) were analyzed cytogenetically.
(8) In animals experimentally immunosuppressed with azathioprine "bracken type" hemangiomas developed in the bladder lining.
(9) It was proved that PT is the carcinogenic principle present in bracken fern, inducing mammary cancer and multiple ileal tumors in high incidences when given orally to female Sprague-Dawley rats.
(10) Here, Main, Sidney Bracken, 65, Paul Radley, 52, and David Robinson, 63, are cooking an outdoor breakfast, after hanging a huge banner around the ramparts of the fort.
(11) The possible carcinogenicity of bracken fern (Pteridium aquilinum, common name: "Broto de Samambaia") which is used as food by the population of Ouro Preto (Minas Gerais, Brazil) and neighboring areas, was studied in rats.
(12) The present study compared results obtained for 62 normally developing preschool children on the Bracken Basic Concept Scale, the Preschool Language Scale, and the Slossen Intelligence Test to determine whether scores on the tests correlated and were equivalent.
(13) The route leads past Bleamoss Beck, then winds its way through the bracken landscape before crossing a grassy hollow to the foot of Wrynose Pass.
(14) Bracken-grazing animals are also heavily immunosuppressed.
(15) Dose dependent toxicity was observed in bracken fern (p less than 0.001).
(16) The carcinogenicity of bracken fern, Pteridium aquilinum, was demonstrated most clearly by the experiment of Evans and Mason in 1965.
(17) Histologic examination of the urinary bladders of albino rats fed bracken fern (Pteris aqulinum) showed epithelial hyperplasia in all test animals after 3 weeks of feeding and nuclear abnormalities at 4 to 6 weeks.
(18) Evidence is presented to shown that this is associated with the presence of bracken fern on high incidence farms and that many of the carcinomas arise in pre-existing virus-induced papillomas.
(19) The two have led to the recognition of the long term cancer dangers of bracken consumption and the vulnerability of a wide variety of species of animals.
(20) The moors, covered with bracken turning a rusty brown, stretched as far as the eye could see.
Braky
Definition:
(a.) Full of brakes; abounding with brambles, shrubs, or ferns; rough; thorny.
