Herbal intoxication. Psychoactive effects from herbal cigarettes, tea, and capsules.

Herbal preparations, designed to be smoked or ingested for "health and happiness", are promoted as legal hallucinogens, euphoriants, and marihuana substitutes. A total of 25 psychoactive substances have been identified in these products, and a number of intoxications have resulted from their short- or long-term use. Physicians should be alerted to the nature of these effects when taking drug histories, and their possible role in the causation of medical complaints should be considered.

An RNA-dependent RNA polymerase activity associated with virions of tomato spotted wilt virus, a plant- and insect-infecting bunyavirus.

An RNA-dependent RNA polymerase activity was found associated with virions of tomato spotted wilt virus (TSWV), a plant- and insect-infecting member of the family Bunyaviridae. Radiolabeled nucleoside triphosphates were incorporated into trichloroacetic acid-precipitable products by detergent-disrupted, purified TSWV virions. Incorporation was reduced to near-background levels when RNase was present in the reaction mixture. The predominantly double-stranded RNA products were RNase-resistant at high but not low salt concentrations. The activity required manganese and was independent of a DNA template. Discrete products of approximately 3.0 kb and heterogeneous smaller products were synthesized that hybridized to purified TSWV RNA and transcripts of cDNA clones encompassing parts of each of the three genomic RNAs. The predominant products were viral sense although significant amounts of viral complementary sense S RNA products were also synthesized.
