Figure 3

Light micrographs of chick biventer cervicis preparations incubated with Krebs solution (control, (a)) or incubated with BmjeTX-I (b) and BjmeTX-II (c) (10 μg/mL each). All images were obtained from longitudinal sections. Notice that in (a) the fibres are normal in appearance, while in (b) and (c) several fibres appear with disrupted myofibrils (white arrows) and hypercontracted zones throughout their length () and nucleus (); HE, per treatment.
