Diuron lacks promoting potential in a rat liver bioassay
(Taylor & Francis Inc, 2007-01-01)
The promoting activity of the herbicide Diuron was evaluated in a medium-term rat liver carcinogenesis bioassay that uses as endpoint immunohistochemically identified glutathione S-transferase positive (GST-P+) foci. Male ...

Absence of chemopreventive influence of propolis on the rat liver altered foci development
(Elsevier Gmbh, Urban & Fischer Verlag, 2010-07-01)
Propolis (bee glue) is a complex mixture of natural substances that exhibits a broad spectrum of biological activities. As the possibility exists that it may exert a chemopreventive role against cancer development, the ...
Absence of carcinogenic and anticarcinogenic effects of annatto in the rat liver medium-term assay
(Elsevier B.V., 2004-10-01)
Annatto (Bixa orellana L.) is a natural food colorant extensively used in many processed foods, especially dairy products. The lower cost of production and the low toxicity, make annatto a very attractive and convenient ...

Promotion of hepatocarcinogenesis by hexachlorobenzene in energy-restricted rats
(Elsevier B.V., 2000-04-28)
The interaction between dietary energy restriction and low dose of the fungicide hexachlorobenzene (HCB) was evaluated in a rat liver medium-term bioassay for carcinogenesis. Male Wistar rats were fed a control or a 50% ...

Tomato oleoresin inhibits DNA damage but not diethylnitrosamine-induced rat hepatocarcinogenesis
(Elsevier Gmbh, Urban & Fischer Verlag, 2008-06-01)
Various studies have shown that lycopene, a non-provitamin A carotenoid, exerts antioxidant, antimutagenic and anticarcinogenic activities in different in vitro and in vivo systems. However, the results concerning its ...
