[Increase in heat production by muscle contraction caused by 2,4-dinitrophenol]. 1978

L D Pchelenko

By means of a highly sensitive thermometric method (1.10--50 C/mm) it was possible to demonstrate that the heat production during a single contraction of the isolated rat diaphragm increased under the influence of 2,4-dinitrophenol (DNP). Low DNP concentrations failed to produce any manifest changes in the resting muscle, but its action was distinct during contraction. With the same muscle contraction force DNP action was followed by an increase (about 1 1/2-fold) of heat production. This fact confirmed a supposition on the leading role of oxidation and phosphorylation uncoupling in the muscle cell respiratory chain in the increase of muscle contraction heat production in the animals after cold adaptation.

UI MeSH Term Description Entries
D009119 Muscle Contraction A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.
