Sodium fluoride/copper naphthenate toxicosis in cattle.
Fourteen cattle on a Kansas pasture died from ingestion of a wood preservative compound containing sodium fluoride and copper naphthenate. Clinical signs included depression, anorexia, ataxia, diarrhea, and recumbency. Grossly visible lesions included perirenal edema, pale kidneys, and forestomach ulceration. All 3 cows that had postmortem evaluations had extensive renal cortical tubular necros...
متن کاملThe effect of subclinical selenium toxicosis on pregnant beef cattle.
A field investigation conducted by the South Dakota Animal Disease Research and Diagnostic Laboratory suggested that subclinical selenium toxicosis in pregnant cows may have contributed to an outbreak of aborted/stillborn calves in a high-selenium region of South Dakota. This study was undertaken to evaluate the relationship between abortion and subclinical selenium toxicosis in the dam and to ...
متن کاملGenetic Tumors of Nicotiana. I. Chemical Composition of N. glauca, N. langsdorffii, & Their F(1) Hybrid.
The F1 hybrid of Nicotiana glauca Grah. and N. langsdorffii Weinm. is well known for its spontaneous tumor-producing ability. Most investigations concerning plant tumors are in the field of genetics or cytology (2,4,6); a few deal with the free amino acid levels of N. glauca, N. langsdorffii and their hybrid (1, 3, 8). However, no references are available on the general chemical composition of ...
متن کاملA century of tobamovirus evolution in an Australian population of Nicotiana glauca.
The evolution over the past century of two tobamoviruses infecting populations of the immigrant plant Nicotiana glauca in New South Wales (NSW), Australia, has been studied. This plant species probably entered Australia in the 1870s. Isolates of the viruses were obtained from N. glauca specimens deposited in the NSW Herbarium between 1899 and 1972, and others were obtained from living plants in...
متن کاملCytological investigations of the interspecific hybrids of Nicotiana tabacum L. x N. glauca Grah.
Interspecific amphihaploid and amphidiploid hybrids between Nicotiana glauca Grah. (2n = 24) and N. tabacum L. (2n = 48) cultivars BY 103 and K 326 were analysed. F1 amphihaploids (2n = 36) were viable and completely self- and cross-sterile, and mostly univalents were present during meiosis (with pairing range from 0 to 5). In some meiocytes, meiotic irregularities were observed, such as sporad...
