We studied the mode of action of type I pyrethroids on the voltage-dependent sodium current from honeybee olfactory receptor neurons (ORNs), whose proper function in antenna is crucial for interindividual communication in this species. Under voltage-clamp, tetramethrin and permethrin induce

1. To examine the metabolic fate of (1RS, trans)- or (1RS, cis)-tetramethrin [3, 4, 5, 6-tetrahydrophthalimidomethyl (1RS, trans)- or (1RS, cis)-chrysanthemate], rat was administered a single oral dose of trans- or cis-[alcohol-14C]tetramethrin at dose levels of 2 or 250 mg/kg.
The aim was to describe a novel form of non-neurogenic coronary artery contraction. Superfused cattle coronary artery preparations in vitro were placed between platinum electrodes and stimulated. The preparations responded to exceedingly brief transmural stimulation (a single ten thousandth of

Four pediculicides were tested against head lice in-vitro. The LT50 for Licid ranged between 10.75 (at conc. 50%) to 25.08 (at conc. 1%). All lice died with conc. 100% within 5 minutes. With Malathion, the LT50 ranged between 4.23 to
Journal of biochemical and biophysical methods, 43(1-3), 411-429 (2000-06-28)
A stepwise approach was used to develop a supercritical fluid extraction (SFE) method for analysis of synthetic pyrethroids (SPs) on a wool matrix, commencing with a simple inert matrix to examine the solubility of the pyrethroids in the extraction fluid
