Temperature dependence of cardiac sarcoplasmic reticulum and sarcolemma in the ventricle of catfish (Clarias gariepinus)
The present study was undertaken to examine the relative contribution of the SR-Ca2+release and sarcolemmal Ca2+ channels in developing the cardiac force at two different temperatures (20 and 30 °C) in the catfish (_Clarias gariepinus_). The sarcolemmal Ca2+ contribution of activator Ca2+ was greater at a test temperature of 30 °C as assessed by verapamil. Whereas the SR-Ca2+ contribution was ... Read more
