(Molecular Carcinogenesis, 1998-03-16) [Artigo]
B6D2F1 mice (45/group) were treated with N-butyl-N-(4- hydroxybutyl)nitrosamine (BBN) or uracil as follows: Group 1 received 0.05% BBN in drinking water for the entire experiment, Group 2 received 5 mg of BBN by gastric ...
Comparison of uroplakin expression during urothelial carcinogenesis induced by N-butyl-N-(4-hydroxybutyl)nitrosamine in rats and mice
(Toxicologic Pathology, 1999-12-08) [Artigo]
The expression of uroplakins, the tissue-specific and differentiation- dependent membrane proteins of the urothelium, was analyzed immunohistochemically in N butyl-N-(4-hydroxybutyl)nitrosamine (BBN)-treated rats and mice ...
Expression of beta-human chorionic gonadotropin (beta-hCG) in non-trophoblastic elements of transitional cell carcinoma of the bladder: possible relationship with the prognosis.
(Revista Paulista de Medicina, 1993-05-01) [Artigo]
Transitional cell carcinoma (TCC) of the bladder is a neoplasm with variability in its clinical behavior. Although there are several studies correlating stage and ABO isoantigen expression with invasiveness, there is no ...

(Inflammation Research, 1999-09-08) [Artigo]
Objective and Design: To determine the alpha-2-macroglobulin (alpha2M) levels in mice during acute and chronic inflammatory responses. Materials and Methods: Inflammation was induced by one of the following stimuli: ...
The hemolytic uremic syndrome as a complication of adriamycin nephropathy
(Renal Failure, 1998-08-13) [Artigo]
Rats treated with two injections of adriamycin (week 0 and week 12) developed glomerusclerosis and severe tubulointerstitial lesions as described in the literature. In addition, a number of glomerular alterations were ...
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, ...

(Histopathology, 1997-02-21) [Artigo]
Pulmonary paracoccidioidomycosis in immunized mice
(Mycopathologia, 1992-07-01) [Artigo]
Paracoccidioidomycosis was induced in immunized (IM) and non-immunized (NI) mice. The histopathology, the number of fungi in the lungs, the cellular (footpad test - FPT and macrophage inhibition factor assay - MIF) and ...
Sputum cytology in the diagnosis of pulmonary paracoccidioidomycosis
(Mycopathologia, 1991-06-01) [Artigo]
The presence of Paracoccidioides brasiliensis was determined in sputum samples from 50 patients with paracoccidioidomycosis using four different techniques: (a) cell-block preparations stained with silver methenamine, (b) ...
