Nitrite Intoxication

The amount of nitrite formed in the rumen after supply of potassium nitrate was decreased considerably by tungsten, which was administered as sodium tungstate to cows orally and by rumen fistula in daily doses of up to 6.6 mg per kg body weight. This effect of tungsten depends on the molybdenum content of the fodder and can be overcome in the case of high molybdenum levels. The relationship between the nitrate intake of the animal, the dose of tungsten administered to the animal daily and the highest concentration of nitrite reached in the rumen is given as a mathematical equation as well as in the form of a triangular diagram. By means of this three-element relationship and as a result of kinetic studies on the action of tungsten, a dosage pattern of tungsten was elaborated. The effectiveness of tungsten as a protective against nitrate intoxication was proved on cows dosed repeatedly as well as with single doses of nitrate up to 500 mg NO3 per kg body weight. It is concluded finally that tungsten offers a high degree of protection against nitrate toxicity to ruminants. (Abstract retrieved from CAB Abstracts by CABI’s permission)

Nitrite Intoxication

ABSTRACT: In a rural property of the Midwestern Minas Gerais, Brazil, three 2.5 to 3-year-old female bovines (7/8 Holstein x 1/8 Gir) weighing approximately 380kg died after showing brownish colored mucosa of conjunctiva and vaginal vestibule, gray-bluish tongue, dyspnea, sialorrhea, tympany, and progression to sternal decubitus and death. In the macroscopic evaluation of one of the bovines, dark (chocolate-colored) blood of difficult coagulation, and intensely cherry-red skeletal and cardiac musculature were observed. Beyond that were observed brownish lungs, kidneys, liver, and encephalon, and all the stomach compartments were dilated due to large amounts of gas. In addition, the carcass exhaled a nitrous odor. The diphenylamine test and the nitrate dosage in the forage (Pennisetum purpureum, “elephant grass”, Napier grass cultivar) used in feeding the bovines showed a high concentration of nitrate, allowing the diagnosis of nitrate/nitrite intoxication. The main factors leading to the poisoning were attributed to excessive fertilization of grass with bovine manure, the occurrence of a drought period followed by a rainy season, lack of adaptation of the bovines to a nitrate-rich diet, and a diet composed almost exclusively of elephant grass. This is the first report of spontaneous nitrate/nitrite poisoning in cattle in southeastern Brazil.

Nitrite Intoxication

The effects of methylene blue, vitamin C, adrenaline and oxytetracycline against sodium nitrite intoxication was studied in Long Evan's (Rattus norvegicus) rats (n=128) in eight groups (A - H). Except control, intoxication was produced by administering sodium nitrite. Rats were treated with methylene blue (group C), vitamin C (group D), adrenaline (group E) and oxytetracycline (group F), and with vitamin C, adrenaline and oxytetracycline (group G); methylene blue, vitamin C, adrenaline and oxytetracycline (Group H). Rats of group C and group H recovered within 24-72 and 13-40 hours, respectively. Other groups showed severe toxic signs including excitement, restlessness, muscle tremor, anoxia, and coma, followed by death within 60 hours. Total erythrocyte count, total leukocyte count, haemoglobin content and packed cell volume were significantly (p<0.01) reduced, and returned to normal at day 14 after methylene blue treatment. The activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were elevated significantly (p<0.01) in all intoxicated groups and within 14 days ALT values reached normal level after methylene blue administration.
