The Orion copper(II) ion-selective electrode responds well to copper(II) ions in aqueous medium. However, in the presence of acetonitrile and copper(I) ions, it can behave as a copper(I) ion-selective electrode with Nernstian behaviour.
RESUMEN
The aim of this paper is to describe clinical pattern and pathogenesis of spontaneous chronic polyarthritis observed in Swiss goats. Roentgenograms, histologic findings, ultrastructural study and microprobe analysis of synovium samples show apatite microcrystal deposit ion. Thus this spontaneous goat disease may be related to apatite microcrystal deposit ion disease in man, so called crystallopathic-hydroxyapatite rheumatism.

Tumours of the nasal cavity are rare in domestic animals, most cases occurring in the dog. Epithelial tumours are the most common type in carnivores (dogs and cats). In general, the same types of tumour occur in domestic animals as occur in man. There was no significant predisposition for breed in dogs, but in both dogs and cats far more males than females were affected. Metastases occurred only rarely.

In seven cats and four dogs of different ages, an epidermoid pulmonary carcinoma has been described. This tumour originates from the orifices or the proximal sections of the ducts of the bronchial glands. The carcinoma, which usually shows no keratinization, penetrates the bronchial mucosa, submucosa and the peribronchial tissue. There is no mucus. Occasionally in the peribronchial neoplastic areas there are adenoid formations, comparable to the combined carcinoma of the WHO classification of lung tumours. Metastases have been restricted to the bronchial lymph nodes.

A 9-year-old horse had numerous firm, painless nodules of the skin and subcutis. Moderately vascular granulation tissue with numerous uni- or multinuclear reticuloendothelial cells was in the nodules and the regional lymph nodes but not in the viscera. By using special stains and electron microscopy, widespread amyloid deposits, mainly in the cytoplasm of reticuloendothelial cells, were identified. Amyloid was probably produced within the reticuloendothelial cells, then expelled from the dying cell and deposited in the intercellular space.

Lung tumours are not common in domestic animals; there has not been the increase in epidermoid carcinomas and anaplastic small-cell carcinomas that has occurred in man this century. Adenocarcinoma is the most common type in animals. The biological behaviour of each type of tumour in animals seems to be much the same as in man. The tumours are described histologically, the main categories being: epidermoid carcinoma, anaplastic carcinoma, adenocarcinoma, combined epidermoid and adenocarcinoma, carcinoid tumours, bronchial gland tumours, benign tumours, and sarcomas.
