RESUMO
Lipofuscin pigments were first detected in the heart of 10 years old humans and in dogs of eighteen months of age. The highest concentration of this type of pigment in the heart of dogs was observed in animals from 6-8 years of age and seems to have no quantitative or qualitative correlation to pathologic processes. From the histochemical point of view the main difference observed is related to the PAS reactivity of the pigment which was negative in humans over 60 years of age and positive in all the different age groups of dogs examined.
O pigmento lipofuscina aparece no miocárdio humano aos 10 anos de idade e no de cães aos 18 meses. A maior concentração deste pigmento no coração de cães foi encontrada a partir dos 6 anos e independe, qualitativa e quantitativamente, de processos patológicos. Do ponto de vista histoquímico a principal diferença observada está relacionada à reação PAS do pigmento que foi negativa em humanos acima de 60 anos de idade e positiva nas outras idades e em todos os diferentes grupos de cães examinados.

RESUMO
Eight cases of cervical anky-losing spondilarthrosis in cats were observed, four of them being submitted to post mortem examination. Clinical and radiographic signs were characteristics, being observed mainly the cervical-dorsal region involvement by ossified newgrown tissue. Histopathological examination of the tissue causing vertebral fusion revealed normal bony tissue with hematogenic osseous marrow.
Investigou-se 8 gatos portadores de espondilartrose ancilosante, sendoque 4 foram necropsiados. Os sinais clínicos e os aspectos radiográficossão bastante sugestivos do processo, inclusive por se observar com maior freqüência o comprometimento da região cérvico-dorsál, por tecido ósseo neoformado. O exame histopatológico do tecido responsável pela fusão das vértebras é ósseo normal com medula óssea hematogênica.
RESUMO
Was studied X Rays, clinical and anatomic pathologies aspects of three cases with tumour of giant cells in the maxillar nasal region and mandible in Dalmatian dogs with age lower at one year old.
Foram estudados os aspectos clínicos, radiográficos e anatomo patológicosde 3 casos de tumor de células gigantes na região maxilo-nasal e mandibular de cães Dálmatas, com idade inferior a um ano.

RESUMO
Both hemosiderin and a chromolipoid (ceroid type) were histochemically characterized in fourteen cirrhotic livers of dogs. These pigments were found within the cells of the interlobular connective tissue as well as within the hepatic and the Kupffer cells. Both carotenoids and melanins were not detected with the use of the present methods.

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
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
In this work we have studied the effect on the blood coagulation of 60 mg of B. jararaca poison injected subcutaneously in serum-productor horses. Tests of coagulation time, coagulation time of recalcified plasma, platelet counts, clot retraction, prothrombin time, consumption of prothrombin and thromboplastin generation were carried out with samples collected before the poison innoculation and 2, 24, 96, 144 and 288 hours after it. A difference statistically significant was found only from the test of prothrombin consumption until 24 hours after, which was greater, when compared with the results obtained before the innoculation.

RESUMO
The usual tests for evaluating the blood clothing phenomena were performed on equines of both sexes. Two groups were employed, one made of 20 normal animals and the other composed of 10 animals which were being used for the preparation of tetanic antisera. No significant difference was found between the results of the two groups, at the 5% level. The mean values found from normal animals were: Coagulation time: 6.3 _+ 1.4 minutes; recalcification tines 229.5 _+ 45.9 seconds; platelets: 138.0 _+ 38.0 x 10-3/mm3; clot retraction: 37.1 _+ 9.3% protrombine time: a - 9.6 _+ 2.1 seconds b - 79.7 _+ 30.3% protrorabine consumption: 77.2 _+ 12.7% tromboplastine formation: a - time of maximal formation: 3.4 _+ 0.8 b - maximal activity in T.C.: 36.0 _+ 10.6 seconds. The results found in the several tests are similar to the ones that have been found for man. However, the recalcificatior and formation of tromboplastine are longer. Also the platelet number is lower.

RESUMO
The use of Frankes lancet for the bleeding time in horses is recommended. The puncture is made in the immediately proximal region of the bum of the frog and the readings are made each 30 seconds. The values obtained were in the average 4 _+0,78 minutes for normal horses and 3,5 _+ 0,88 for horses injected with tetanus toxin. The two averages do not differ significantly at the 0,95 level.
