contracture/никотин

The induction of cleft palate by Nicotiana glauca (wild tree tobacco) during the first trimester of pregnancy was compared between Spanish-type goats and crossbred western-type sheep. Cleft palate was induced in 100% of the embryonic/fetal goats when their pregnant mothers were gavaged with N.

Many species of lupines contain quinolizidine or piperidine alkaloids known to be toxic or teratogenic to livestock. Poison-hemlock (Conium maculatum) and Nicotiana spp. including N. tabacum and N. glauca contain toxic and teratogenic piperidine alkaloids. The toxic and teratogenic effects from

Three piperidine alkaloid containing plants, Conium maculatum (poison-hemlock), Nicotiana glauca (tree tobacco) and Lupinus formosus (lunara lupine), induced multiple congenital contractures (MCC) and palatoschisis in goat kids when their dams were gavaged with the plant during gestation days 30-60.

Sustained inhibition of fetal movement in livestock species, induced by several poisonous plants, can result in numerous skeletal-contracture malformations. Lupines are responsible for a condition in cattle referred to as "crooked calf syndrome" that occurs when pregnant cattle graze teratogenic

A number of isomers and homologues of nicotine, (2-, 3- and 4-pyridylmethyl)- and [2-(2-, 3- and 4-pyridyl)ethyl]- dialkylamines and trialkylammonium salts, have been prepared. They have been tested for their ability to act like acetylcholine in causing contracture of the chick biventer-cervicis

1. Series of pyridylalkyl- and substituted phenylalkyl-trimethylammonium salts, triethylammonium salts, diethylamines and di-n-propylamines have been made. The substituents in the benzene ring were nitro, chloro, bromo, methoxy, hydroxy and amino groups and the alkyl residues had one, two, or three

Isoarecolone methiodide has been reported previously to be a potent agonist at peripheral nicotinic-cholinergic receptors. Both isoarecolone methiodide and isoarecolone HCl can produce contractures of the frog rectus abdominis muscle and can inhibit binding of [3H]-(-)-nicotine to rat brain
