Tuberculous pyloric stenosis.

A case of pyloric stenosis, caused by abdominal tuberculosis and presenting as an inoperable neoplasm in a member of the indigenous population of the British Isles, is reported. The need for histological confirmation of suspected inoperable malignant tumours is stressed. The pathogenesis and management of the condition are discussed.

Changes of blood metabolites in horses after racing, with particular reference to uric acid.

Changes in concentration of a number of blood metabolites in 30 thoroughbred horses were recorded after an 1110 metre race. No significant changes occurred in blood urea or aspartate aminotransferase during the three hours after racing. Plasma sodium, potassium and calcium levels were increased immediately after racing but had returned to normal one hour after racing.

Changes of plasma uric acid levels in horses after galloping.

Two horses were alternately galloped and cantered at 48 h intervals in a cross over trial. Galloping produced a rise in plasma lactic and uric acids. The lactic acid decreased in concentration whereas the uric acid increased in the hour after exercise.
