The actions of a chromatographically identified extract of the marine dinoflagellate Ostreopsis lenticularis, named ostreotoxin-3 (OTX-3), were studied on frog isolated neuromuscular preparations. OTX-3 (1–10μg ml−1) applied to cutaneous pectori

Dibromosceptrin and clathrodin are alkaloid compounds purified from tropical marine sponges of the genus Agelas. Experiments done using the whole cell configuration of the patch clamp technique revealed that these compounds have neurotoxic activity.

Pharmacological studies on the body wall musculature of the sedentary polychaete Sabellastarte magnifica show a potential neurotransmitter role for monoamines and neuropeptides in this organism. All catecholamines induced contraction of longitudinal

Immunohistochemical studies of the nervous system of Sabellastarte magnifica, a sedentary polychaete, showed the presence of neuropeptide expressing cells and fibers within the double ventral nerve cord. Immunoreactivity to cholecystokinin, neuropept

The contractility of guinea pig ileum and frog skeletal muscle is inhibited in solutions containing 0.4 to 2.5 M formamide (FMD). Contrary to mammalian vis ceral muscle, this blocking action is not reversed when frog muscles are transferred back to i

Strips of guinea pig ileum lose over 70% of their contractility when bathed in Krebs-Ringer solution containing 0.4-0.9 M formamide (FMD). This effect is not accompanied by an appreciable loss of tissue water and is totally reversed by washing the pr

Buchtal and collaborators reported thirty years ago an excitatory action of low (10 −3 M) concentrations of ATP on frog muscle, as well as in increase in the sensitivity of the muscle to ACh. These effects have been re-investigated employing both i

Succinic anhydride (SA) dissolved in Ringer solution buffered with N-tris (hydroxymethyl) methyl-2-aminoethane sulphonic acid (SA-TES solution) potentiates the depolarizing action of acetylcholine (ACh, 10-40 microM) on frog muscle and the tension in

Synaptic receptors are regulated by allosteric modulators which may increase or decrease their response to agonists. For the nicotinic cholinergic receptor (AChR) very few positive modulators have been reported, although a number of allosteric inhibi

INACTIVATION of acetylcholinesterase (AChE) causes the half-decay times of the endplate currents (e.p.cs) and miniature e.p.cs (m.e.p.cs) to increase from about 1.5–2.0ms to 3.0–10.00 ms, times far too long to be accounted for by removal of the t
