The materials in paraffin blocks were cut 5 micrometers thick, stained with HE and submitted to histopathological examination.
H- ras immunohistochemical expression and molecular analysis of urinary bladder lesions in enzootkca adult cattle exposed to bracken fern. In cattle with BEH, hematuria was observed in all cases, followed by progressive weight loss. We also preferred to use the term transitional or squamous carcinoma with areas of pseudo-glandular differentiation to the one of carcinoma of transitional cells with lumen similar to the gland, used by AFIP Murphy et al.
In BEH form, the bladder had nodules, large neoplastic masses, red urine, papilomas, and hemorrhages. On the other hand, small variations between the different classifications in nomenclature sometimes just reflect a preference for one or other term.
Animals submitted to us for post-mortem examination, had their organs collected immediately after death.

Factors which may affect ptaquiloside levels in milk: Bovine enzootic haematuria in Queensland. The relationship between EMS and RS, physicochemical test and complementary chemical tests were evaluated. Masuda I ; Rafael A.

Possibly there is a relationship between the period during which the plant is ingested and the amount of carcinogens contained in the plant in each outbreak.
