Effect of sciatic nerve crush on enzyme activities of skeletal muscles of the rat. 1979

B Holmes, and E W Yamada

Weight loss and reduction in specific activity of cytochrome oxidase of both red (soleus) and white muscles (gastrocnemius and plantaris) of the rat was greatest 5 days after sciatic nerve crush (p less than 0.001) and then became minimal. In neither was there a significant, concomitant loss of protein. By 19 days, the specific activity of cytochrome oxidase was the same in both muscle types. The specific activity of lactate dehydrogenase was reduced significantly (p less than 0.001) in the white muscles, to a value approaching that of the red soleus by 19 days postoperatively, but remained unaltered in the soleus. Nerve crush is proposed as a model experimental system for studying neural regulation of skeletal muscle metabolism.

UI	MeSH Term	Description	Entries
D007770	L-Lactate Dehydrogenase	A tetrameric enzyme that, along with the coenzyme NAD+, catalyzes the interconversion of LACTATE and PYRUVATE. In vertebrates, genes for three different subunits (LDH-A, LDH-B and LDH-C) exist.	Lactate Dehydrogenase,Dehydrogenase, L-Lactate,Dehydrogenase, Lactate,L Lactate Dehydrogenase

D003576	Electron Transport Complex IV	A multisubunit enzyme complex containing CYTOCHROME A GROUP; CYTOCHROME A3; two copper atoms; and 13 different protein subunits. It is the terminal oxidase complex of the RESPIRATORY CHAIN and collects electrons that are transferred from the reduced CYTOCHROME C GROUP and donates them to molecular OXYGEN, which is then reduced to water. The redox reaction is simultaneously coupled to the transport of PROTONS across the inner mitochondrial membrane.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012584	Sciatic Nerve	A nerve which originates in the lumbar and sacral spinal cord (L4 to S3) and supplies motor and sensory innervation to the lower extremity. The sciatic nerve, which is the main continuation of the sacral plexus, is the largest nerve in the body. It has two major branches, the TIBIAL NERVE and the PERONEAL NERVE.
