Cutaneous lymphosarcoma in a stallion.

Multiple cutaneous lymphosarcomas were diagnosed in an 8-year-old Thoroughbred stallion presented for evaluation of lumps on its scrotum. Histological examination of skin biopsy samples showed a homogenous pattern of lymphoid tissue suggestive of a T-cell lymphosarcoma. Immuno-histochemical tests showed a positive reaction to Rabbit/Anti-Human T-Cell, CD3 antibodies confirming T-cell lymphosarcoma. The animal was not treated and was subsequently euthanased.

How to reduce air pollution by Cupressus pollen?

Cypress trees are among the most famous trees of the Mediterranean region. The origin of Cupressus sempervirens is apparently in the East Mediterranean. A nice description of the site of origin of Cupressus was provided by the Roman philosopher Plinius: "cypress trees sprout spontaneously on Mt. Ida on the island of Crete, whenever the soil there is disturbed". The aesthetic shape of the trees, the quality of their timber and their adaptation to harsh environmental conditions has attracted people. Certain varieties of the tree (e.g., var. Pyramidalis) were spread rapidly all over the Mediterranean and since the 16th century were introduced into the Western Hemisphere and other parts of the world. During historical times, Cupressus sempervirens was so widely used in the East Mediterranean countries that it reached the brink of extinction. Nowadays it is planted on a large scale as an ornamental plant as a windbreak and as a forest tree. Such plantations have various impacts on their environment, many positive ones, some negative ones, and some disastrous ones. This last aspect is where cypresses come in.

Relationship between potassium administration, hyperkalaemia and the electrocardiogram: an experimental study.

Hyperkalaemia affected the equine myocardium. The minimum plasma potassium concentration required to induce electrocardiographic changes was 6.2 mmol/litre and severe cardiotoxic effects were observed at levels of 8.0 to 10.1 mmol/litre in this experimental situation. The most consistent sign of hyperkalaemia was broadening and flattening of the P wave, which was generally associated with a change in T waves in the chest lead from negative to positive. The more pronounced the hyperkalaemia, the less pronounced the P wave and the more peaked positive the T wave. Severe hyperkalaemia was associated with various arrhythmias invariably associated with the presence of broad flat or absent P waves and upright T waves in chest leads. Caution against extrapolation from the experimental to the clinical situation must be exercised because of many complex interacting factors. Hyperkalaemia is difficult to induce experimentally and, unless associated with disease, is unlikely to occur in the horse.
