Histochemical analyses of muscle injury induced by venom from Argentine Bothrops alternatus (víbora de la cruz)
Histochemical methods were used to study necrosis of skeletal muscle fibers induced by Bothrops alternatus snake venom from Argentina. Rats with a body weight between 220–270 g, were used. Animals received an i.m. venom injection (800 μg) in the gastrocnemius. To determine creatinphosphokinase activ...
