Effects of uracil calculi on cell growth and apoptosis in the BBN- initiated Wistar rat urinary bladder mucosa
(Teratogenesis Carcinogenesis and Mutagenesis, 1999-07-28) [Artigo]
The different potential of initiated and non-initiated urinary bladder mucosa (UBM) to develop neoplasia was quantitatively evaluated in the male Wistar rat. Initiation of carcinogenesis was accomplished with N-butyl-N-(4- ...
Natural killer activity in a medium-term multi-organ bioassay for carcinogenesis
(Japanese Journal Of Cancer Research : Gann, 1999) [Artigo]
Natural killer (NK) cell activity was evaluated after the initiation and promotion steps in a medium-term multi-organ bioassay for carcinogenesis. NK cell activity was assessed in vitro by Cr51 release assay at the 4th and ...
The use of a mixture of somatic and culture filtrate antigens in the evaluation of the immune response to Paracoccidioides brasiliensis
(Journal of Medical and Veterinary Mycology, 1991-10-11) [Artigo]
Three Paracoccidioides brasiliensis antigens, namely a culture filtrate preparation, a somatic antigen and a mixture of equal parts of the two, were tested by two serological techniques against sera from patients with ...

CYTOPLASMIC AND PLASMA-MEMBRANE ULTRASTRUCTURE OF PARACOCCIDIOIDES-BRASILIENSIS YEAST-PHASE CELLS AS REVEALED BY FREEZE-ETCHING
(Mycological Research, 1990-12-01) [Artigo]
Using a freeze-etch technique the cytoplasmic and plasma membrane ultrastructure of Paracoccidiodies brasiliensis yeast-phase cells was studied. The multinucleate yeast-phase cells which grow by simultaneous multiple ...
EFFECT OF MACROPHAGE BLOCKADE ON THE RESISTANCE OF INBRED MICE TO PARACOCCIDIOIDES-BRASILIENSIS INFECTION
(Mycopathologia, 1995-06-01) [Artigo]
The effect of macrophage blockade on the natural resistance and on the adaptative immune response of susceptible (B10.D2/oSn) and resistant (A/Sn) mice to Paracoccidioides brasiliensis infection was investigated. B10.D2/oSn ...
Adenocarcinoma de cólon com diferenciação neuro-endócrina e escamosa. Relato de caso.
(Arquivos de Gastroenterologia, 1992-04-01) [Artigo]
A tubular adenocarcinoma of the colon with solid area composed by small cells that was found by immunohistochemistry study using antibody to neuron-specific enolase (NSE) to possess neuroendocrine differentiation is related. ...
DELAYED-TYPE HYPERSENSITIVITY RESPONSE IN AN ISOGENIC MURINE MODEL OF PARACOCCIDIOIDOMYCOSIS
(Mycopathologia, 1994-06-01) [Artigo]
The specific delayed-type hypersensitivity (DTH) response was evaluated in resistant (A/SN) and susceptible (B10.A) mice intraperitoneally infected with yeasts from a virulent (Pb18) or from a non-virulent (Pb265) ...
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 ...
EXPERIMENTAL PARACOCCIDIOIDOMYCOSIS OF HAMSTER INOCULATED IN THE CHEEK POUCH
(Mycopathologia, 1994-11-01) [Artigo]
We compared the granuloma morphology and immune response of hamsters inoculated with Paracoccidioides brasiliensis (Pb) into the cheek pouch, which lacks lymphatic drainage, and into the footpad, which is rich in lymphatics. ...
