Channel Catfish Ictalurus punctatus
We used a two-compartment, clearance volume-based model to examine rubidium and cesium Ž . pharmacokinetics in channel catfish Ictalurus punctatus after intravascular administration. We compared the apparent volumes of distribution in the central and peripheral compartments and the intercompartmental and whole-body clearances of both metals at 20.0 8C and 27.5 8C. Biological half-times of Rb we...
متن کاملLiquid chromatographic analysis of vitamin K1 in milk-based infant formula with matrix solid-phase dispersion.
A liquid chromatographic method for vitamin K1 in milk-based infant formula is described. The vitamins are extracted from infant formula by matrix solid-phase dispersion and quantitated by reversed-phase chromatography with fluorescence detection. Vitamin K1 is converted to the fluorescent hydroquinone with a postcolumn zinc reductive reactor. The limit of detection is 12 pg, and the limit of q...
متن کاملHormonal Control of Osmoregulation in a Stenohaline Catfish, Ictalurus Punctatus
When channel catfish (lchtalurus punctatus) in fresh water (FW) were hypophysectomized, plasma osmolality decreased significantly after 24 hrs, and the maximum reduction was seen after 2 days. When they were transferred from FW to dilute seawater (20-40% SW), plasma osmolality of the sham-operated fish was consistently higher than the osmolality of the environmental water, whereas the osmolalit...
متن کاملPharmacokinetics, tissue distribution, and metabolism of flumequine in channel catfish ž / Ictalurus punctatus
Ž . The pharmacokinetics and metabolism of the fluoroquinolone drug flumequine FLU were Ž . Ž . examined after intravascular 1 mgrkg or oral 5 mgrkg dosing in channel catfish. Parent FLU concentrations in plasma declined slowly after intravascular dosing, with a half-life of 25 h. After Ž . oral dosing, FLU concentrations in plasma were highest 3.1 mgrml at 14 h after dosing; absorption and eli...
متن کاملDetermination of Malathion and α-Endosulfan Residue in Khazar Rice Using Matrix Solid Phase Dispersion and HPLC
An extraction method based on matrix solid phase dispersion (MSPD) and high performance liquid chromatography with UV detection for quantification of two widely used pesticides (Malathion and α-Endosulfan) in Khazar rice from north of Iran were investigated. The ratio of solid phase (adsorbent) to sample, types of eluting solvent and its volume were optimized to achieve the highest recoveries f...
