My research work is to evaluate wound healing effect of different compounds in diabetes rats. For this purpose I used Streptozotocin drug at proper dose. After diabetes induced in rats we created wound on dorsum of rats after giving anaesthesia. But in my two trial rats mortality was more than 50% within 10-15 days. My trial duration is 21 days. We followed all standard protocols in trial.
Plz help me in this query.
