Figure 3.

A. Shows the total or absolute % (not normalised to controls) of disintegration of the three grades of mucin, in the vitro model; B. Shows the total or absolute % of disintegration of the three grades of mucin, in the in vivo model; C. Shows a comparison of the in vitro with that of the in vivo disintegration; D. Shows the relationship between hardness index of the three grades of mucin samples in the in vitro and in vivo studies, to their respective normalised or Nett % disintegration. The controls show how much they actually contribute to the total (absolute) % of disintegration; SM = soft mucin; SHM = semi hard mucin; HD = hard mucin; (T) = treated with bromelain + N-acetyl cystein
