Results of another typical case on time-dependent wound-healing progress. Similarly to Figure 6, Figure 7 also demonstrates a time-dependent wound healing progress, for an 80-year-old male PU patient. Figure 7-a shows the features photographed at the former period for routine care treatment alone. On the other hand, Figure 7-b presents ones photographed at the latter period for routine care treatment plus HW intake. The latter period in using HW intake shows a marked improved outcome.
