Di(2-ethylhexyl) phthalate (DEHP) is a peroxisome proliferator agent that is widely used as a plasticizer to soften polyvinylchloride plastics and non-polymers. Both occupational (e.g., by inhalation during its manufacture and use as a plasticizer of polyvinylchloride) and environmental (medical
Potentially preneoplastic hepatocellular hyperplastic foci and hepatocellular neoplasms were studied in weanling male B6C3F1 mice that received a single i.p. injection (80 mg/kg) of diethylnitrosamine (DEN) at 4 weeks of age, followed by oral administration of phenobarbital (PB) or
The current United States Environmental Protection Agency (EPA) classification of di(2-ethylhexyl)phthalate (DEHP) as a B2 "probable human" carcinogen is based on outdated information. New toxicology data and a considerable amount of new mechanistic evidence were used to reconsider the cancer
Previous studies suggest that a higher ratio of primary to secondary metabolites of di-2-ethylhexyl phthalate (DEHP), reflective of a slower DEHP conversion rate, is associated with a greater physiologic effect. We examined associations of several individual characteristics and lifestyle factors
Analysis of the carcinogen bioassay of di(2-ethylhexyl) phthalate (DEHP) has shown that the designated maximum tolerated dose was exceeded in the low- and high-dose groups of male rats, in the high-dose group of female rats, and in the low- and high-dose groups of female mice. Significant
A bioassay of di(2-ethylhexyl)phthalate, the most commonly used plasticizer for polyvinylchloride polymers, for possible carcinogenicity was conducted by feeding diets containing 6,000 or 12,000 ppm of the test chemical to groups of 50 male and 50 female F344 rats and 3,000 or 6,000 ppm to groups of
Activation of peroxisome proliferator-activated receptor α (PPARα) by di-(2-ethylhexyl) phthalate (DEHP) has an anti-inflammatory effect. This study investigated the potential combined influence of PPARα, tumor necrosis factor α-induced protein 3 (TNFAIP3/A20), and tumor necrosis factor
Preneoplastic and neoplastic liver and lung lesions were studied in male B6C3F1 mice given a single injection (80 mg/kg) of N-nitrosodiethylamine (DEN) intraperitoneally at 4 weeks of age, followed 1 week later by oral exposure to di(2-ethylhexyl)-phthalate (DEHP; at 6000 ppm in the diet), butylated
Extracts of Aloe vera Linne have been found to exhibit cytotoxicity against human tumour cell lines. This study examines the anti-tumour effects of di(2-ethylhexyl)phthalate (DEHP) isolated from Aloe vera Linne, in human and animal cell lines. Its anti-mutagenic effects were examined using
Objective: To investigate the effects of Shoutai pills (a traditional Chinese medicinal preparation) on immune functions and oxidative stress in pregnant rats exposed to di(2-ethylhexyl) phthalate (DEHP).
The effects of dimethyl phthalate, diethyl phthalate, diisobutyl phthalate, di-n-butyl phthalate, benzylbutyl phthalate, di-2-ethylhexyl phthalate were investigated on human prostate cancer cell lines DU145 and PC3 in vitro.
Standards of dimethyl phthalate, diethyl phthalate, di-isobutyl phthalate,
The level of di-(2-ethylhexyl) phthalate (DEHP) is elevated in chronic kidney disease patients undergoing dialysis. However, statins are unable to reduce the cardiovascular events in chronic dialysis patients. In this study, we investigated the effects of DEHP on statin-conferred pleiotropic effects
The objective of the study is to explore the anticancer activity of di-(2-ethylhexyl) phthalate (DEHP) isolated from Calotropis gigantea flower against Ehrlich ascites carcinoma cells (EAC) in Swiss albino mice. The activity of DEHP was evaluated at doses of 10, 20 and 40 mg kg-1 body mass applied
The effect of prolonged dietary administration of the peroxisome proliferating plasticizer di(2-ethylhexyl)phthalate (DEHP) was studied on liver carcinogenesis initiated by N-2-fluorenylacetamide (FAA) and compared with that of the neoplasm-promoter phenobarbital (PB). Also, DEHP was studied as an
Peroxisome proliferation is inducible in hepatocytes of rodent and nonrodent species by structurally dissimilar hypolipidemic drugs and certain phthalate ester plasticizers. The induction of peroxisome proliferation appears to be a tissue specific response limited largely to the hepatocyte.
