The rate of healing was determined by measurements of the wound volumes and the number of days for complete repair .  Ten r and omly selected controls ( mean age 25·0 years and wound volume 32·3 ml . ) were matched against ten who were given the drug ( mean age 24·6 years and wound volume 54·5 ml . ) .  The days ±S.E. for healing averaged 80·1±13·7 in the controls and 45·8±2·6 ( 
    Output:
    
Overall , there was no evidence of a beneficial effect of treatment with zinc sulphate on the number of ulcers healed .
