title: Regeneration following orthotopic transplantation of entire plantaris muscle in Sprague Dawley rats.
abstract: Regeneration of rat plantaris muscle has been studied without predeneration. The original muscle fibres were completely degenerated within one week, but were completely regenerated at the end of experiment. The weight of regenerate showed 51% recovery. The breadth, length and total area of muscle and number of muscle fibres was less by 42, 37, 26 and 29% respectively, compared to control muscle at the end of experiment. The diameter of regenerated fibres was almost normalized at the end of experiment. The number and diameter of nuclei in the regenerate was more than that of control which coincides with the increase in DNA and RNA contents. The protein contents after an initial loss started increasing and continued to do so till the end of the experiment. The better regeneration of the plantaris muscle seems to be due to the presence of supporting gastrocnemius muscle.
