The levator auris longus muscle of the mouse: A convenient preparation for studies of short- and long-term presynaptic effects of drugs or toxins
We describe here the levator auris longus muscle of the mouse as a convenient neuromuscular preparation for the in vitro study of presynaptic effects of drugs and toxins applied in vivo in young orExpand

Ciguatoxin enhances quantal transmitter release from frog motor nerve terminals
1 Ciguatoxin (CTX), a marine toxin produced by the benthic dinoflagellate Gambierdiscus toxicus, is responsible for a complex endemic disease in man known as ciguatera fish poisoning. In the presentExpand

Nerve terminal sprouting in botulinum type-A treated mouse levator auris longus muscle
The marked outgrowth of the motor nerve terminal arborization triggered by an in vivo local injection of Clostridium botulinum type-A toxin in the mouse levator auris longus muscle was studied withExpand

Changes of quantal transmitter release caused by gadolinium ions at the frog neuromuscular junction
1 The actions of the trivalent cation, gadolinium (Gd3+), were studied on frog isolated neuromuscular preparations by conventional electrophysiological techniques. 2 Gd3+(450 μm) applied to normal orExpand

Facilitation and delayed release at about 0 degree C at the frog neuromuscular junction: effects of calcium chelators, calcium transport inhibitors, and okadaic acid.
1. We studied two-pulse facilitation and delayed release at 0 degree C, because at low temperature facilitation is enhanced and extended whereas delayed release is increased. Our major goal was toExpand

The wheat proteins puroindoline‐a and α1‐purothionin induce nodal swelling in myelinated axons
The effects of two basic cysteine-rich lipid-binding proteins isolated from wheat seedlings, puroindoline-a and α1-purothionin, were studied on single frog myelinated axons stained with theExpand

Terminal sprouting in mouse neuromuscular junctions poisoned with botulinum type a toxin: Morphological and electrophysiological features
Functional properties of terminal sprouts elicited by an in vivo injection of Clostridium botulinum type A toxin were studied in endplates of the Levator auris longus muscle of the mouse poisonedExpand

Recycling and refilling of transmitter quanta at the frog neuromuscular junction
Fluorescent dyes have been used at the frog neuromuscular junction to label synaptic vesicular membrane. Retrieved membrane is reformed into vesicles, which are released along with pre‐existingExpand

Ciguatoxin extracted from poisonous moray eels Gymnothorax javanicus triggers acetylcholine release from Torpedo cholinergic synaptosomes via reversed Na+ –Ca2+ exchange
Ciguatoxin (CTX) (0.1 pM to 10 nM) added to a suspension of Torpedo synaptosomes incubated in Ca(2+)-free medium caused no detectable acetylcholine (ACh) release. However, subsequent addition of Ca2+Expand
