Formaldehyde was administered for 104 weeks in drinking water supplied ad libitum at concentrations of 1500, 1000, 500, 100, 50, 10, or 0 mg/L to groups of 50 male and 50 female Sprague-Dawley rats beginning at seven weeks of age. Control animals (100 males and 100 females) received tap water only. Acetaldehyde was administered to 50 male and 50 female(More)
BACKGROUND In a previous study conducted at the Cesare Maltoni Cancer Research Center of the European Ramazzini Foundation (CMCRC/ERF), we demonstrated for the first time that aspartame (APM) is a multipotent carcinogenic agent when various doses are administered with feed to Sprague-Dawley rats from 8 weeks of age throughout the life span. OBJECTIVE The(More)
BACKGROUND Aspartame (APM) is a well-known intense artificial sweetener used in more than 6,000 products. Among the major users of aspartame are children and women of childbearing age. In previous lifespan experiments conducted on Sprague-Dawley rats we have shown that APM is a carcinogenic agent in multiple sites and that its effects are increased when(More)
Vinyl acetate monomer (VAM) was administered in drinking water supplied ad libitum at doses of 5,000, 1,000, and 0 ppm (v/v) to 17-week-old Sprague-Dawley rats (breeders) and to 12-day embryos (offspring). Treatment lasted for 104 weeks; thereafter, animals were kept under control conditions until spontaneous death. VAM was found to cause an increase in(More)
BACKGROUND Studies indicate that extracts and purified components from black cohosh inhibit the growth of human breast cancer cells, but the molecular targets and signaling pathways have not yet been defined. PURPOSE This study examines the pharmacological mechanisms and toxicological effects in the short term of the herb black cohosh on female(More)
Aspartame (APM) is one of the most widely used artificial sweeteners in the world. Its ever-growing use in more than 6000 products, such as soft drinks, chewing gum, candy, desserts, etc., has been accompanied by rising consumer concerns regarding its safety, in particular its potential long-term carcinogenic effects. In light of the inadequacy of the(More)
Background In 2002 the International Agency for Research on Cancer classified extremely low frequency magnetic fields (ELFMF) as a possible carcinogen on the basis of epidemiological evidence. Experimental bioassays on rats and mice performed up to now on ELFMF alone or in association with known carcinogens have failed to provide conclusive confirmation.(More)
BACKGROUND/AIM This study examines the chemopreventive potential and action of the herb black cohosh on Sprague-Dawley rats. MATERIALS AND METHODS Female Sprague-Dawley rats were treated with an extract of black cohosh enriched in triterpene glycosides (27%) at 35.7 (Group I), 7.14 (Group II), 0.714 (Group III) or 0 mg/kg b.w. for 40 weeks starting from(More)
BACKGROUND Experimental rodent bioassays performed up to now have failed to provide conclusive confirmation of the carcinogenicity of extremely low frequency magnetic fields (ELFMF). OBJECTIVES To evaluate the potential synergistic carcinogenic effects of concurrent exposure to ELFMF and formaldehyde in four groups of male and female Sprague-Dawley rats.(More)
Background Aspartame (APM) is a well-known intense artificial sweetener used in more than 6,000 products. Among the major users of aspartame are children and women of childbearing age. In previous lifespan experiments conducted on Sprague–Dawley rats we have shown that APM is a carcinogenic agent in multiple sites and that its effects are increased when(More)
