Comparison of respiratory sparing effect between pancuronium and three new nondepolarizing muscle relaxants in rats.

Journal of anesthesia

Kaneko M, Hua L.
PMID: 28921314
J Anesth. 1998 Dec;12(4):185-188. doi: 10.1007/BF02481728.

PURPOSE: There is a large difference in sensitivity between respiratory muscles and other limb muscles. This phenomenon, known as the respiratory sparing effect (RSE), is well established withd-tubocurarine, pancuronium, and succinylcholine. The purpose of this study is to evaluate...

Effects of Corticotrophin Releasing Factor, Muscarine and Somatostatin on Rubidium and Potassium Efflux from Mouse AtT-20 Pituitary Cells.

The European journal of neuroscience

Luini A, Brown DA.
PMID: 12106055
Eur J Neurosci. 1990 Feb;2(2):126-131. doi: 10.1111/j.1460-9568.1990.tb00404.x.

Effects of secretagogues and anti-secretagogues of ACTH secretion on K+ permeability in the clonal pituitary cell line AtT-20 were measured by recording 86Rb or 42K efflux. Efflux was accelerated by the secretagogues K+, corticotrophin, forskolin, isoprenaline, and the Ca-ionophore...

Long-lasting depolarization of leech neurons mediated by receptors with a nicotinic binding site.

The Journal of experimental biology

Szczupak L, Edgar J, Peralta ML, Kristan WB.
PMID: 9600871
J Exp Biol. 1998 May 21;201:1895-906.

The serotonergic Retzius neurons of the leech midbody ganglia respond in a complex manner to pressure pulses of acetylcholine (ACh) applied onto their soma with a fast depolarization followed by a slower hyperpolarization and an additional delayed long-lasting depolarization....

Nicotinic acetylcholine receptor is involved in acetylcholine regulating stomatal movement.

Science in China. Series C, Life sciences

Wang H, Wang X, Zhang S, Lou C.
PMID: 18726222
Sci China C Life Sci. 1998 Dec;41(6):650-6. doi: 10.1007/BF02882908.

In animal cells, actions of acetylcholine depend on its binding to specific receptors. Activation of nicotinic acetylcholine receptor can affect the membrane permeability to ions directly. As concerned about acetylcholine regulating stomatal movement, nicotinic acetylcholine receptor may also be...

CURARE ALKALOIDS FROM CHONDODENDRON TOMENTOSUM.

Science (New York, N.Y.)

Wintersteiner O, Dutcher JD.
PMID: 17789877
Science. 1943 May 21;97(2525):467-70. doi: 10.1126/science.97.2525.467.

Crystalline d-tubocurarine has been isolated in good yield from curare prepared from a single plant species, namely, Chondodendron tomentosum. This result establishes with certainty the botanical origin of this compound and substantiates the supposition that it is this species...

Cerebellar cGMP varies with motor function and respiratory gas exchange.

Neuroscience letters

Mueller RA, Lundberg D, Frye GD, Mailman RB, Breese GR.
PMID: 19605262
Neurosci Lett. 1978 Nov;10(1):89-93. doi: 10.1016/0304-3940(78)90017-4.

Paralysis of rats with d-tubocurarine decreased cerebellar guanosine 3': 5'-cyclic monophosphate (cGMP) content to about one third of normal values when arterial oxygen and carbon dioxide were maintained at normal values. In addition, altering arterial carbon dioxide tensions in...

Excitatory effect of ATP on rat area postrema neurons.

Purinergic signalling

Sorimachia M, Wakamoria M, Akaikeb N.
PMID: 18404492
Purinergic Signal. 2006 Sep;2(3):545-57. doi: 10.1007/s11302-006-9004-4. Epub 2006 May 30.

ATP-induced inward currents and increases in the cytosolic Ca(2+) concentration ([Ca](in)) were investigated in neurons acutely dissociated from rat area postrema using whole-cell patch-clamp recordings and fura-2 microfluorometry, respectively. The ATP-induced current (I (ATP)) and [Ca](in) increases were mimicked...

Update on neuromuscular pharmacology.

Current opinion in anaesthesiology

Meistelman C.
PMID: 17019121
Curr Opin Anaesthesiol. 2001 Aug;14(4):399-404. doi: 10.1097/00001503-200108000-00004.

Since the introduction of d-tubocurarine into clinical practice, neuromuscular relaxants have been widely used in anaesthesia. Although their clinical use is easy, several points still require further attention and research. There is still a need for a drug with...

Cytotoxic activity of acetylcholine receptor ligands.

Biochemistry and molecular biology international

Blishchenko EY, Mirkina II, Mernenko OA, Yatskin ON, Satpaev DK, Strizhkov BN, Karelin AA.
PMID: 19856291
Biochem Mol Biol Int. 1997 Jul;42(4):739-47. doi: 10.1080/15216549700203171.

Acetylcholine receptor ligands were studied for cytotoxicity in K562 human erythroid leukemia tumor cells. Cytotoxicity of carbachol, an agonist of acetylcholine receptors, atropine, an antagonist of muscarinic acetylcholine receptor, neurotoxin 11 (NT II) from Naja naja oxiana cobra venom...

TTX, cations and spider venom modify avian muscle tone in vitro.

Journal of venom research

Herzig V, Hodgson WC, Rowan EG.
PMID: 21544174
J Venom Res. 2011 Jan 02;2:1-5.

Agents that reduce skeletal muscle tone may have a number of useful clinical applications, e.g., for muscle spasticity and other muscle disorders. Recently, we reported that the venoms of two species of Australian theraphosid (Araneae, Theraphosidae) spiders (Coremiocnemis tropix...

Influence of procainamide on the neuromuscular blockade caused by rocuronium and investigation on the mechanism of action of procainamide on the neuromuscular junction.

Revista brasileira de anestesiologia

Conventional insecticides targeting acetylcholinesterase (AChE) typically show high mammalian toxicities and because there is resistance to these compounds in many insect species, alternatives to established AChE inhibitors used for pest control are needed. Here we used a fluorescence method...
