An over-the-counter Chinese medicine, Chan Su, is used as a cardiotonic agent. We demonstrated significant digoxin-like immunoreactivity in various organic and aqueous extracts of Chan Su. For example, when a 20-microL aliquot of an aqueous extract of Chan Su powder (1 mg/mL) was added to a 2-mL aliquot of a drug-free serum, the observed digoxin-like(More)
Asian and Siberian ginsengs contain glycosides with structural similarities to digoxin. We studied potential interference of ginseng in 5 digoxin immunoassays in 3 Asian (2 liquid extracts, 1 capsule) and 3 Siberian ginseng preparations (1 liquid extract, 2 capsules). With the fluorescence polarization immunoassay (FPIA), we observed apparent digoxin(More)
Serum cortisol levels were evaluated in mice following intravenous administration of purified mycobacterial glycolipid trehalose 6,6'-dimycolate (TDM). C57BL/6 mice develop lung granulomas in response to TDM, while A/J mice are deficient in this process. Administration of TDM to C57BL/6 mice led to a rapid reduction in serum cortisol, concurrent with(More)
The New Caledonian endemic hydroptilid genus Caledonotrichia Sykora (Trichoptera) is reviewed and 6 new species are described: Caledonotrichia bifida, Caledonotrichia capensis, Caledonotrichia minuta, Caledonotrichia ouinnica, Caledonotrichia sykorai and Caledonotrichia vexilla. Together with the established species for which revised diagnoses are given,(More)
We review the New Caledonian representatives of the Australasian endemic hydroptiline genus Acritoptila, based on examination of a considerable collection of material in the Swedish Museum of Natural History and of types of previously established species. A key for identification of males is given and includes 3 species newly described here: A. parallela(More)
