Lea and Febiger, Philadelphia. Another problem for the exact determination of the frequency of these neoplasms is the possible variation in the nomenclature used by different pathologists. Services on Demand Journal.

Comparative study of carcinogenic activity in each part of bracken. This should be taken into account in the interpretation of the results. Due to these miscellaneous lesions, it was frequently difficult or impossible to establish which was the main alteration and the chronological order of emergence of enziotica lesions, as the tumors and the metaplastic alterations seemed to arise, at the same time, on several sites of the mucous membrane.

Spontaneous cases of chronic poisoning by Pteridium aquilinum in cattle were studied. The most logical explanation is that the local immunological reaction would impede the spread of the neoplasia.


Exchange offer not hematuriz. Histological examination of new cases of bovine enzootic hematuria revealed several undescribed bladder neoplasms. Regarding the incidence of the main neoplasms found in cattle with BEH in our study, it is not easy to make exact comparisons with the data found in the literature.

Haemangiosarcomas originating from haemangiomas were also observed.

First, because few authors mention the frequency of the different histological types. Enzoofica Helianthus, Rio de Janeiro. RESULTS The changes found in the bladder of the animals were divided into neoplastic and non-neoplastic; the last ones were subdivided into inflammatory, hyperplastic and metaplastic. However, only a few bladder fragments were available from many animals.

Sheep tumours in Northeast Yorkshire. We opted for the first designation, in function of the marked anaplasia present in these alterations. Foi realizada a necropsia e os materiais coletados. In some animals this process was accompanied by dysplasia and hyperplasia of vessels of the stroma and vessels of the bladder muscles, besides metaplastic alterations of the connective tissue surrounding those vessels, into mixoid connective tissue cases and Editora Pallotti, Santa Maria.


Other processes were also found inside some vessels, such as the proliferation of endothelial cells of the intima of arteries, forming small “papillae” in the vascular lumen, or even of the media, with marked thickening of the vascular muscle layer cases and V Haematological and biochemical observations on the blood of cattle suffering from haematuria.

High incidence area of cattle cancer with a possible interaction between an environmental carcinogen and a papilloma virus. Exchange offer is not applicable with this product.

Pathology of bracken poisoning in cattle. Neoplastic processes, visualized separately in a section, without hematudia proximity, were classified separately. For instance, foci of hyperplastic urothelium with “intestinal” or mesonephroid changes differentiated at the base into carcinoma “in situ” or into “intestinal” adenocarcinoma, sometimes already enzootoca a clear infiltrative tendency.

Normal hematology with comments on response to disease, p. The elucidation of the cause s of this “barrier against metastases” and their relationship with the chemical carcinogenesis induced by the ptaquiloside may be of interest in future studies that aim to combat cancer in man and animals.
