Abstract

Light microscopic examination of frog sartorius muscle incubated in a hornet venom-Ringer solution reveals vacuoles across the muscle fibers, usually evenly spaced. After more than 10-15 min incubation most of the muscle filaments are divided by enlarged vacuoles into strips of myofilaments. Electron microscopic study reveals the T-tubules and the terminal cisterns to be very greatly extended, giving the whole myofilament system a disrupted appearance. The possible reasons for these changes produced by the hornet venom are discussed.
