[Myocardial infarction in the cat].

The authors describe two cases of myocardial infarction evaluated during an anatomo-histopathological study on the cat's cardiovascular system. The authors discuss the pathogenetic hypotheses and their role in comparative pathological studies.

[The pathology of mitral valve prolapse in dogs].

The authors present investigations of the prolapse of the mitral valves in dogs. In 18 cases there were dogs with a prolapse, in 6 dogs there was a prolapse of the tricuspid valves, and in 3 cases a prolapse of both valves was observed. In all cases prolapse occurred together with endocardiosis of the valves or as a consequence of it.

[Neurotoxic syndrome of sheep due to the ingestion of plants of the Mediterranean scrub: clinical, histopathological, histochemical and ultrastructural observations].

A severe neurological disorder was observed during a very dry season, in sheep pasturing on land with mediterranean vegetation. During the crisis, lasting 5-20", ataxia and convulsions were the main clinical signs. Brain congestion, spongy appearance of the liver, interstitial nephritis and hyperpigmentation of visceral lymph nodes were the most important macroscopic lesions. Histopathological, histochemical and ultrastructural findings confirmed liver and kidney lesions and showed considerable neurovisceral storage of lipofuscin. Although further toxicological and experimental studies are needed to elucidate the origin of the disease, the Authors attribute the outbreak of the neurological syndrome to the ingestion of a neurotoxin containing plant.

[Tuberculosis in animals].

Tuberculosis is a well known disease for immemorial time and very diffuse in animals. Today the technological progress of zoo technology decreased the incidence of tuberculosis in animals and at the same time, it modified the epidemiological characteristics in all animal species. We can confirm that in intensive pig- and chicken raising tuberculosis is now quite inexistent. About sanitary reclamation, unfortunately Italy takes a very low position among European countries, since the eradication of bovine tuberculosis is not settled in some provinces. At Piedmont, tubercular lesions in female genital apparatus of regularly slaughtered cows are been shown in about 7% of all examined animals (4500), percentage tantamount to 30-40% of pulmonary tuberculosis. The diagnostic difficulties come from the fact that also in cows tubercular disease can be clinically silent for a long time. In man, animal tuberculosis can be consequent upon an occupational risk. Also in town, the contact with domestic animals proposes as important the problem of a careful antitubercular survey.

Histological reactions of porous tip endocardial electrodes implanted in sheep.

The tissue reaction caused by a sintered tip electrode is compared with that of a platinum-iridium tip electrode in a work which employs implantation in sheep and follow-up of the implant for up to 90 days. Clinical tests and anatomo-pathological examination of the histological sections were performed. The results show a remarkably rapid fixation to the heart for the porous electrode with formation of limited inflammatory process, a thin fibrous capsule and modest alteration of the endocardial tissue. Conversely, the platinum-iridium electrode does not fix even in long periods and therefore continuously rubs the endocardial surface. Chronic inflammation and formation of remarkably thick connective capsule results, under which the heart seems mode deeply altered.
