Cancer patients diagnosed with solid tumors and undergoing a first course of chemotherapy were randomized to either conventional care or a 10 contact 20 week cognitive behavioral intervention designed to reduce emotional distress. Three hypotheses were tested. First, a test for a group effect found that patients in the intervention who entered the trial(More)
In this review we have evaluated the relationship between peroxisome proliferation and hepatocarcinogenesis. To do so, we identified all chemicals known to produce peroxisome proliferation and selected those for which there are data (on peroxisome proliferation and hepatocarcinogenesis) which meet certain criteria chosen to facilitate comparison of these(More)
The ability of 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC), 3,5-diethoxycarbonyl-4-ethyl-1,4-dihydro-2,6-dimethylpyridine (EDDC) and griseofulvin to induce porphyria in primary cultures of mouse hepatocytes has been examined. Exposure of cultured mouse hepatocytes to DDC, EDDC or griseofulvin resulted in a marked inhibition of ferrochelatase which was(More)
1-[4-(3-Acetyl-2,4,6-trimethylphenyl)-2,6-cyclohexanedionyl]-O-eth yl propionaldehyde oxime (for short ATMP) is a novel porphyrogenic agent causing hepatic protoporphyria in the mouse. Mice given a single dose of the drug showed 24 h later a 70% inhibition of liver ferrochelatase and marked accumulation of protoporphyrin. These changes were not seen in(More)
PURPOSE To describe a randomized trial of a cognitive behavioral intervention on reducing symptom severity among patients diagnosed with solid tumors and undergoing a first course of chemotherapy and to determine whether the intervention had an additive or interactive effect on symptom severity in the presence of supportive care medications. PATIENTS AND(More)
Identification of the proximate peroxisome proliferator(s) derived from di (2-ethylhexyl) adipate (DEHA) has been achieved using primary hepatocyte cultures derived from different species and cyanide-insensitive fatty acyl CoA oxidase (PCO) as a marker enzyme for peroxisome proliferation. In rat and mouse hepatocytes, the parent compound (DEHA) had no(More)
Some xenobiotics display estrogenic activity in in vitro and/or in vivo systems. Previous studies by Gajdova et al. have shown that polysorbate 80 (also known as Tween 80) administered by intraperitoneal injection to neonatal female rats on days 4-7 after birth produced estrogenic effects including earlier vaginal opening, prolongation of the estrus cycle(More)
2-[1-(Ethoxyimino)propyl]-3-hydroxy-5-(2,4,6-trimethylphenyl) cyclohex-2-enone (ETC) is a novel alkyl ketone herbicide. Continuous administration of ETC to mice for 28 days resulted in marked liver enlargement and severe intrahepatic cholestasis. These effects have been shown to result directly from a rapid and marked accumulation of porphyrin in the liver.(More)
The ability of 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC), 3,5-diethoxycarbonyl-4-ethyl-1,4-dihydro-2,6-dimethyl pyridine (EDDC) and griseofulvin to induce porphyria in primary cultures of mouse and rat hepatocytes was determined. Exposure of mouse hepatocytes to DDC, EDDC or griseofulvin (5-100 mum) for 4 days resulted in a marked inhibition of(More)
