Rhoeo discolor is a legendary plant used for treatment of superficial mycoses in Mexican traditional medicine. Despite its extended use, it is not known whether it has side-effects. An ethanolic crude extract from Rhoeo discolor was prepared, its mutagenic capacity was investigated by the Ames test,

The root extracts of a Chinese herb, Polygonum multiflorum Thunb., have been used for centuries as an internal medicine to improve liver and kidney functions. In this study, we evaluated the antimutagenic property of this drug with the Tradescantia micronucleus (Trad-MCN) assay. The Trad-MCN

Three isomers of the promutagen phenylenediamine at mM concentrations were plant-activated and induced mutation in stamen hairs of Tradescantia clone 4430. The rank order of the mutagenicity of the isomers was: o-phenylenediamine > m-phenylenediamine > p-phenylenediamine with corresponding mutagenic

Ethanolic extract of Casearia sylvestris is thought to be antimutagenic. In this study, we attempted to determine whether this extract and casearin X (a clerodane diterpene from C. sylvestris) are protective against the harmful effects of airborne pollutants from sugarcane burning. To that end, we

Widely used throughout the world as traditional medicine for treating a variety of diseases ranging from cancer to microbial infections, members of the Tradescantia genus show promise as sources of desirable bioactive compounds. The bioactivity of several noteworthy species has been well-documented

BACKGROUND Rhoeo discolor, a medical plant from Mexico, is known to be an antioxidant and chemoprotective antimutagen. Rhoeo discolor ethanolic extract (EERD) is a complex mixture, so in this study its antimutagenic mechanisms were further evaluated. METHODS Employing Ames test, with uvrB- and uvrB+

Recent experiments showed that 5-fluorouracil (5FU), cisplatin (CDDP), etoposide (ET), and imatinib mesylate (IM), which are currently among the most widely used anticancer drugs, cause damage of the genetic material in higher plants. The aim of the present study was to determine whether mixtures of

The experiment carried out on the Cosmos 110 biosatellite is a step further in radiobiological investigations performed in outer space and differs appreciably from flight experiments conducted on board the Vostok and Voskhod spacecraft. The difference lies, firstly, in the integral dose of cosmic

Cytostatic drugs are among the most toxic chemicals which are produced. Many of them cause damage of the genetic material which may affect the fertility of higher organisms. To study the impact of the widely used anticancer drugs [cisplatin (CisPt), etoposide (Et), and 5-fluorouracil (5-FU)] on the
