OBJECTIVE To investigate electrocardiogram changes due to scorpion stings and association between oxidative stress index, body oxidant/antioxidant system and the electrocardiogram changes. METHODS The study was conducted at the Faculty of Medicine, Gaziantep University, Turkey, between May 2009 and October 2010. It comprised 44 patients admitted to the emergency department for scorpion sting,...
The Shaker B K(+) conductance (G(K)) collapses when the channels are closed (deactivated) in Na(+) solutions that lack K(+) ions. Also, it is known that external TEA (TEA(o)) impedes the collapse of G(K), and that channel block by TEA(o) and scorpion toxins are two mutually exclusive events. Therefore, we tested the ability of scorpion toxins to inhibit the collapse of G(K) in 0 K(+). We have f...
Scorpion toxins have been central to the investigation and understanding of the physiological role of potassium (K⁺) channels and their expansive function in membrane biophysics. As highly specific probes, toxins have revealed a great deal about channel structure and the correlation between mutations, altered regulation and a number of human pathologies. Radio- and fluorescently-labeled toxin i...
