The terminal period is associated with abdominal ascites, dyspnea, and piloerection. Purine analogues are important therapeutic tools due to their affinity to enzymes or receptors that are involved in critical biological processes. (6) Humane Endpoints Paclitaxel has experimental vesicant potential in the ID mouse skin model. It can then break through the skin and cause an open sore (or ulcer) on the skin surface. The experiment ended for individual mice either when the tumour size exceeded 1500 mm 3, the tumour showed ulceration, the mouse was seriously ill, tumour growth blocked the movement of the mouse . .nwa-header-widget{ Mouse Tumor Scoring 1.
