[The effect of lasalocid on apparent digestibility, characteristics of rumen fermentation and fattening and slaughter output of bulls].

Archiv fur Tierernahrung

Richter GH, Flachowsky G.
PMID: 1963770

Four digestion experiments with 5 wethers each (Feeding: artificially dried grass; 0, 15, 30 or 60 mg lasalocid per animal and day), two short time experiments (Exp. 1: 3 rumen fistulated sheep; feeding; artificially dried grass; 0, 15, 30...

Studies on the ionophorous antibiotics. XII. Effects of ionophore lysocellin on cation distribution and respiration in mitochondria.

The Journal of antibiotics

Mitani M, Koenuma M, Otake N.
PMID: 145423
J Antibiot (Tokyo). 1977 Oct;30(10):829-35. doi: 10.7164/antibiotics.30.829.

The effects of the ionophore lysocellin on the movements of Ca2+, Mg2+ and alkali metal cations and its effect on energy utilization by rat liver mitochondria have been investigated. At a concentration of 0.05 micrometer, lysocellin induced dissociation of...

Depression of spontaneous and ionophore-induced neurotransmitter release by Salmonella.


Person RJ.
PMID: 223876
Experientia. 1979 Jun 15;35(6):801-2. doi: 10.1007/BF01968259.

Exposure of frog neuromuscular junctions to heat-killed, lyophilized Salmonella typhimurium (SR 11) produces an early increase in spontaneous transmitter release followed by depression of release and blockade of the obligatory release usually induced by ionophore X537A.

Ionophores alter hepatic concentrations of intermediary carbohydrate metabolites in steers.

Journal of animal science

Benz DA, Byers FM, Schelling GT, Greene LW, Lunt DK, Smith SB.
PMID: 2599982
J Anim Sci. 1989 Sep;67(9):2393-9. doi: 10.2527/jas1989.6792393x.

The effects of ionophores on liver weight and function were determined in finishing steers (n = 24; avg weight 440 kg). Steers were group-fed one of three treatments (control, lasalocid or monensin at 33 mg/kg feed) for 46 d...

The biphasic active transport of calcium by the fragmented sarcoplasmic reticulum as revealed by the flow dialysis method.

European journal of biochemistry

Mermier P, Hasselbach W.
PMID: 819267
Eur J Biochem. 1976 May 01;64(2):613-20. doi: 10.1111/j.1432-1033.1976.tb10341.x.
Free Article

The calcium accumulated by the fast uptake has an apparent association constant of 0.8 X 10(6) M-1 and a maximum of 80 nmol/mg protein. The fast uptake and the initial rate of the slow uptake show a similar dependence...

Ionophore-induced Cl- transport in human erythrocyte suspensions: a multinuclear magnetic resonance study.

Biochemical and biophysical research communications

Wittenkeller L, Mota de Freitas D, Ramasamy R.
PMID: 1575760
Biochem Biophys Res Commun. 1992 Apr 30;184(2):915-21. doi: 10.1016/0006-291x(92)90678-e.

To investigate the effect of ionophores on Cl- distribution in human erythrocyte suspensions, we measured the membrane potential by using 19F and 31P NMR methods. Incubation of human erythrocytes with 0.005 mM of the neutral ionophores valinomycin and nonactin...

Effect of lasalocid on performance of lactating dairy cows.

Journal of dairy science

Weiss WP, Amiet BA.
PMID: 2312881
J Dairy Sci. 1990 Jan;73(1):153-62. doi: 10.3168/jds.S0022-0302(90)78659-6.
Free Article

Thirty-two midlactation dairy cows were fed either a typical dairy diet or the same diet plus 340 mg lasalocid/d for 98 d. Diets were 65% forage (alfalfa and corn silage) and 35% concentrate (DM basis). Lasalocid did not affect...

Depolarizing effects of the ionophores X-537A and A23187 and their relevance to secretion.

British journal of pharmacology

Cohrane DE, Douglas WW.
PMID: 1100156
Br J Pharmacol. 1975 Jul;54(3):400-2. doi: 10.1111/j.1476-5381.1975.tb07582.x.
Free PMC Article

The ionophore X-537A depolarized frog skeletal muscle fibres about 10 mV in 10 min and a further 30 mV or so over the next 50 minutes. With A23187, depolarization was relatively feeble and delayed in onset but was hastened...

Some effects of the ionophore X-537A on the isolated rat tail artery.

Canadian journal of physiology and pharmacology

Palatý V, Todd ME.
PMID: 667722
Can J Physiol Pharmacol. 1978 Jun;56(3):474-82. doi: 10.1139/y78-071.

The effects of micromolar concentrations of the ionophore X-537A (RO 2-2985) were studied using isolated preparations of the rat tail artery. The ionophore causes complete release of catecholamines from adrenergic nerves, which is the sole cause of the transient...

European journal of clinical investigation

Mira-Moser F, Schofield JC, Orci L.
PMID: 176032

The ionophore A23187 increased the release of rat growth hormone in the presence of a phosphodiesterase inhibitor, 3-isobutyl-1-methylxanthine; a second ionophore X537A inhibited growth hormone release induced by the methylxanthine. A23187 did not alter rat growth hormone release in...
