Conclusion one of possible pathogenetic causes of pvs in cats is the decrease of dopamine 結論多巴胺的減少可能是形成持續性植物狀態貓的重要因素之一。
Results the level of dopamine in cerebrospinal fluid in the cats with pvs was obviously lower than that of control groups 結果持續性植物狀態貓的腦脊液中多巴胺含量顯著降低。
Conclusion : higher clinical stages were accompanied with greater number , wider diameter or faster blood flow of pvs 結論:隨小腿擴張交通靜脈數目增加、內徑增寬、血流速度升高,臨床表現加重。
