n, number of patients (for functional studies, numbers of muscle strips used are given in parenthesis). The ages of the patients are given as mean±SEM with ranges in parenthesis. For functional studies, tissues were used after overnight storage in fresh Krebs solution at 4˚C (188 tissues), 44 on the day of surgery and 7 on the day of surgery and after storage.
