MACROSCOPIC ANATOMICAL AND PATHOLOGICAL ASPECTS FOUND IN TWO COMMON BREED DOGS EXPERIMENTALLY INTOXICATED WITH VITAMIN D3 (CHOLECALCIFEROL)

Nowadays we can no longer imagine our social, economic or cultural life without the wide use of chemical rodenticides. Together with the latest generation anticoagulant raticides, the cholecalciferol based rodenticides (vitamin D3) have a significant importance (in North America and Western Europe). In base of the observations in this paper, we try to anticipate the moment when the cholecalciferol based raticides will be introduced on the Romanian market, moment which should not surprise the veterinary clinician or the pet owner. The experimental study carried out on ten common breed dogs unfortunately led to the death of two of the subjects, on which we did a necropsy. With this opportunity, one noted the constant presence of the congestion aspects of the parenchimatous organs, miocardosis and the right heart dilatation, as well as the congestion (with or without ulcerations) of the fundic area of the stomach. The lesions had various degrees of occurrence, however without reaching the development of calcinosis areas (squeaky per section) in the parenchimatous organs, surely due to the short term development of the experimentally introduced intoxication.
