This should discuss the significance of the results. What were the experiments trying to show? You will need to consider what mast cells do and suggest which molecule is responsible for the effect on ileal contraction. The discussion section should also mention the different types of receptor and their intracellular signal transduction pathways. In particular, which drug interacts with which pathway? You will need to critically analyze your data. Is it consistent with previous studies in the literature?
Write the discussion using the graphs provided (attached) and scientific articles.
