Distribution of Radiocarbon After Intramammary, Intrauterine, or Ocular Treatment of Lactating Cows with Carbon-14 Nitrofurazone

Distribution of radiocarbon after intramammary, intrauterine, or ocular treatment of lactating cows with carbon-14 nitrofurazone.

Three lactating Holstein cows (634 to 698 kg) were dosed, respectively, with 65.6 mg (44.5 microCi/mg), 131.2 mg (20.1 microCi/mg), or 8.4 mg (141.3 microCi/mg) of [14C]nitrofurazone by intramammary, intrauterine, or topical ocular administration. Intramammary and intrauterine treatments were single doses; ocular treatment was daily for 4 consecutive d (2.1 mg/d). Cows were slaughtered after 72...

detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
