The effect of the intramuscular injection of bupivacaine hydrochloride on selected morphological characteristics and contractile properties of adult rat extensor digitorum longus muscle was studied. Recovery of normal fiber size was already present 30 days after bupivacaine injection and at 90 days

✦ Synopsis
Contractile responses were studied in autotransplanted and sliced extensor digitorum longus (EDL) muscles at different times after the surgical intervention (3 and 12 months). The contraction of autotransplanted and sliced EDL muscles remained strongly dependent upon the extracellular Ca 2+ concentration ([Ca] o ) 3 and even 12 months after the intervention. It could be suggested that in autotransplanted and sliced EDL muscles, neural control could be involved in the persistent dependence of contractility toward [Ca] o .

Two types of nerve lesions were performed at birth in rat extensor digitorum longus muscle: sciatic nerve transection (group A) and sciatic nerve crush allowing further reinnervation (group 6). Contractile responses were then studied at different times after the denervation (7, 14, 30, and 60 days)
Background: In order to understand the cellular basis underlying the progressively poorer restorative capacity of long-term denervated muscle, we determined the effects of long-term denervation on the muscle fibers and satellite cell population of the rat extensor digitorum longus (EDL) muscle. Met
