juniperus virginiana/neoplasms

(1) Shavings from the Eastern Red Cedar (Juniperus virginiana) were examined for three diverse biological properties, i.e. enzyme induction, procarcinogenicity and insecticidal activity. (2) The ability of a cedar environment to stimulate liver drug-metabolizing enzymes in mice was confirmed by

C3H-A-vy and C3H-A-VY-FB mice transferred from our colony to the laboratory of Dr. J. R. Sabine in Australia had a markedly reduced incidence of both hepatomas and mammary tumors. Sabine and co-workers (J Natl Cancer Inst 50: 1237-1242, 1973) attributed the low incidence of tumors in their

Leaves of Eastern red cedar (Juniperus virginiana L. Cupressaceae) have been reported to contain podophyllotoxin, a pharmaceutical compound used to manufacture drugs for treatment of cancer, rheumatoid arthritis, genital warts, psoriasis, and multiple sclerosis. Podophyllotoxin content of leaves of

The biological effect of exposure to wood dust depends on its composition and the content of microorganisms which are an inherent element of the dust. The irritant and allergic effects of wood dust have been recognised for a long time. The allergic effect is caused by the wood dust of subtropical

Occupational exposure to wood dusts has been well established as a cause of nasal cancer, dermatitis, and pneumonites from molds growing in wood chips. With the exception of studies on western red cedar asthma, there is a dearth of information on the respiratory toxicity of wood dust exposure. This

Woodworking is known to be associated with nasal cancer and with western red cedar asthma, but research is inconsistent with regard to respiratory health effects among furniture workers. The authors tested the hypotheses that employment in a North Carolina hardwood furniture plant was related to the

(-)-Matairesinol is a central biosynthetic intermediate to numerous 8-8'-lignans, including the antiviral agent podophyllotoxin in Podophyllum species and its semi-synthetic anticancer derivatives teniposide, etoposide, and Etopophos. It is formed by action of an enantiospecific secoisolariciresinol
