RESUMO
The present study refers to a male animal from the canine species, of indefinite breed, about 12 years old, that for several days had been presenting edema of the head and cervical region, including the former limbs and sternum region. Clinical examination showed high temperature (39,5 C ) bilateral purulent nasal discharge, mixed dyspnea, besides inappetence and prostration. Radiographic examination was impaired by the animal"s condition at the time; other tests performed gave no Information suggesting a circulatory obstruction near the cranial cava. Necropsy revealed a tumor of about 4x2x2 cm located in the luminal cranial cava vein. Histological examination showed it to be a fibrosarcoma.
O relato refere-se a animal da espécie canina, sem raça definida, com aproximadamente 12 anos de idade, que há dias apresentava edema de cabeça, região cervical, atingindo inclusive os membros anteriores e região do esterno. O exame físico mostrava ainda temperatura retal 39,5C, corrimento nasal bilateral purulento, dispneia mista, além de inapetência e prostração. O quadro radiográfico foi prejudicado pelo estado em que o animal se apresentava e os demais exames não forneceram informações que auxiliassem a elucidar o quadro clínico, sugerindo tratar-se de obstrução circulatória na altura da cava cranial. O exame necroscópico mostrou tumoração de aproximadamente 4 x2 x2 cm localizada no lúmen da veia cava cranial que, ao exame histológico, demonstrou tratar-se de fibrossarcoma.

RESUMO
The macroscopic and microscopic lesions produced by Trichuris vulpis in the caecum of dogs were studied. The macroscopic alterations were described as large thickening of the caecum walls and the presence of petechiae and suffusion. In the caecal lumen, the number of parasites found was large as well as the encreased production of mucus. The histological examen in the infected caeca showed that the parasite do not produce deep alterations in the caecal wall. These alterations were characterized by edema in the submucosa and celular infiltrate linpho-plasmocitary prevalent. In the mucosa superfice the number of parasites was large as well as the quantity of muco present; the lymphoid folicules showed a marked hyperplasia. Using histochemical methods, it was verified the secreted muco presented the same characteristics as that produced by the caliciform normal cells.
Estudou-se as lesões macroscópicas e microscópicas produzidas por Trichuris vulpis no ceco de cães. As alterações macroscópicas se caracterizaram por grande espessamento da parede de ceco e presença de pctequias e sufusões. No lúmen cecal era grande o número de parasitas, bem como foi evidenciada acentuada produção de muco. O exame histológico dos cecos infestados demonstrou que os parasitas não produzem alterações profundas na parede cecal. As alterações eram caracterizadas por edema da submucosa e por infiltrado celular prevalentemente linfo-plasmocitário. Na superfície da mucosa era grande a quantidade de muco e de parasitas e os folículos linfoides demonstraram acentuada hiperplasia. Através de métodos histoquímicos foi verificado que o muco secretado apresentava as mesmas características do muco produzido pelas células caliciformes normais.

RESUMO
An adrenal tumour found in a dog has been identified as meduloepithelioma by its histological characteristics. The tumour showed many infiltrations and was able to produce metastasis in the lung, kidney and heart. This is probably the first case of such tumor described in dogs.
Estudamos tumor da adrenal em cão que, pelas suas características histológicas, foi classificado como meduloepitelioma. O blastoma se mostrou altamente infiltrativo, com capacidade de metástases à distância: no pulmão, no rim e no coração. Provavelmente o primeiro caso em cães.
RESUMO
A bitch 10 years old presented an ovarian neoplasm. Through its characteristics the tumour was classified as a dysgerminoma. The histological study revealed high malignity, but no metastasis was noted but no conclusion were drawn because of the lack of clinical information.
Estudamos neoplasia ovariana em cadela com 10 anos de idade. As características do tumor possibilitaram diagnóstico de disgerminoma. O estudo histológico revelou alta malignidade, não sendo, no entanto, observadas metástases. Comentamos a evolução do tumor, sem concluir sobre este aspecto do problema, pela falta de dados clínicos.

RESUMO
The normal levels of cholinesterase in thorough-bred horses are studied in this paper. Twenty-six mares were utilized, with ages varying from 2 to 20 years, and they were kept in very good clinical conditions. These animals were distributed in two groups, according to their ages: the first group from 2 to 10 years old, the second one, from 11 to 20 years. The statistical analysis of the results, by applying the t test, demonstraded that the data obtained are significant at a level of 2%.It was verified that in the animals under observation, the cholinesterase contents determined by the eletrometrical method of Michel keeps a distinct relationship between the two age groups. By the results obtained, one should consider that the animals are less susceptible to an intoxication by inhibitory agents of Cholinesterase than older animals, when submitted to the same amount of the toxical agent.
Estudamos no presente trabalho os níveis normais de colinesterase em eqüinos PSI. Utilizamos animais do sexo feminino, com idades compreendidas de 2 a 20 anos, mantidos em ótimas condições clínicas, divididos em 2 grupos etários; o primeiro de 2 a 10 anos e o segundo de 11 a 20 anos. A análise estatística dos resultados, pela aplicação do teste t demonstrou que os dados obtidos são francamente significativos ao nível de 2%.Verificamos que nos animais submetidos a esta observação, o teor de colinesterase, determinado pelo método eletrométrico de Michel, guarda uma relação distinta entre os dois grupos etários. Pelos resultados obtidos, devemos considerar que os animais jovens são menos susceptíveis a intoxicação por agentes inibidores da colinesterase do que animais mais idosos, quando submetidos à mesma dose de agente tóxico.

RESUMO
Spontaneous occurance of hepatic capilariasis in a dog is presented by the A.A. The lesions were submitted to macro and microscopic studies and the direct examination of oviform structures could be characterized as eggs of Capillaria hepatica (Bancroft, 1893) Travassos, 1915 Capillariidae Trichuroidea. After a throughbly bibliographic search, the A.A. concluded that this is the firest time a case of dogs hepatic capilariasis is described in the State of São Paulo.

RESUMO
The authors present observations on 20 cases of sporotrichosis, 12 in dogs and 8 in cats, during 18 months of observation. They conclude: 1) In cats and dogs, sporotrichosis is much more frequent than literature indications. 2) Laboratory diagnosis can"t present troubles, since the agent is relatively abundant in the lesions. 3) Evolution of the disease is very slow and it seems not to affect the general conditions of the patients, since it limits it"s action to the cutaneous tissue. 4) Transmission by direct contact seems to be very difficult.

RESUMO
The author in this paper studies a case of a cromophobe adenoma of the Hypophisis in bovine. He comments about the rarity of these tumours not only in human but also in Veterinary medicine, and its consequences. He also studies the macroscopic and microscopic aspects and considers that this tumour is probably the first ever found in Brazilian literature.

RESUMO
A case of squamous cell carcinoma of the urinary bladder in the bitch, is reported in this paper. About two months ago, the animal showed signs of hematuria, taking during this time antibiotics drugs. The diagnosis of tumor was made mainly by the clinical findings showing the urine with some anormal cells; an irritative tipe of the blood picture and a tumoral mass by the pneumocystography, into the urinary bladder wall. The radiological technique and the surgery as well as the histopathology were studied about this subject.

RESUMO
Clinical, surgical and pathological data pertaining to a case of primary lymphosarcoma in a cat, with bilateral kidney involvement, are presented. A bibliographical survey on the incidence of feline lymphatic tumors, as well as a clinical discussion of the case is made. The authors share Feldmans opinion regarding the origin of lymphosarcomas, classifying the neoplasm by them observed, in accordance with Whartin et al. as a lymphoblastic lymphosarcoma. Judging from the more specialized literature, this is a rare observation to be made in the feline species.
