Aberrant crypt foci and colon cancer: comparison between a short- and medium-term bioassay for colon carcinogenesis using dimethylhydrazine in Wistar rats
(Brazilian Journal of Medical and Biological Research, 2002-03-01) [Artigo]
Aberrant crypt foci (ACF) in the colon of carcinogen-treated rodents are considered to be the earliest hallmark of colon carcinogenesis. In the present study the relationship between a short-term (4 weeks) and medium-term ...
Primary sclerosing cholangitis associated with severe ulcerative colitis in a young man
(Autopsy and Case Reports, 2013) [Artigo]
Primary sclerosing cholangitis, a chronic progressive cholestatic liver disease, is the most serious hepatobiliary complication of ulcerative colitis (UC). The authors present the case of a severe and intractable form of ...
Liver response to low-hexachlorobenzene exposure in protein- or energy-restricted rats
(Food and Chemical Toxicology, 1991-12-01) [Artigo]
The individual effects of protein deficiency and energy restriction on liver response to low-hexachlorobenzene (HCB) exposure were investigated in adult male Wistar rats. In rats fed either the low-protein or control diet, ...
Clinicopathologic features and outcome of mycophenolate-induced colitis in renal transplant recipients
(Clinical Transplantation, 2014-11-01) [Artigo]
Reports on the clinical course of mycophenolic acid (MPA)-related colitis in kidney transplant recipients are scarce. This study aimed at assessing MPA-related colitis incidence, risk factors, and progression after kidney ...

(Human & Experimental Toxicology, 2008-06-01) [Artigo]
The mushroom Agaricus blazei (Ab) has been widely used in folk medicine to treat various diseases including cancer. No information is available on its possible protective effects on the development of colon cancer. The ...
Protective effects of Ginkgo biloba against rat liver carcinogenesis
(Chemico-biological Interactions, 2008-05-09) [Artigo]
Ginkgo biloba (EGb) has been proposed as a promising candidate for cancer chemoprevention and has shown protective effects on the liver against chemically induced oxidative injury and fibrosis. The potential beneficial ...
