A Comparison of the Potency of the Oxime HLö-7 and Currently Used Oximes (HI-6, Pralidoxime, Obidoxime) to Reactivate Nerve Agent-Inhibited Rat Brain Acetylcholinesterase by in vitro Methods

Acta Medica, 2005
1. The efficacy of the oxime HLö-7 and currently used oximes (pralidoxime, obidoxime, HI-6) to reactivate acetylcholinesterase inhibited by various nerve agents (sarin, tabun, cyclosarin, VX) was tested by in vitro methods. 2. Both H oximes (HLö-7, HI-6)

The Effect of Parathion on Red Blood Cell Acetylcholinesterase in the Wistar Rat

Journal of Toxicology, 2016
Organophosphorus (OP) pesticide poisoning is a significant problem worldwide. Research into new antidotes for these acetylcholinesterase inhibitors, and even optimal doses for current therapies, is hindered by a lack of standardized animal models.

Serum cholinesterases are differentially regulated in normal and dystrophin-deficient mutant mice

Frontiers in Molecular Neuroscience, 2012
The cholinesterases, acetylcholinesterase and butyrylcholinesterase (pseudocholinesterase), are abundant in the nervous system and in other tissues. The role of acetylcholinesterase in terminating transmitter action in the peripheral and central nervous ...

Latent acetylcholinesterase in secretory vesicles isolated from adrenal medulla [PDF]

, 1981
A new procedure is described for the preparation of highly purified and stable secretory vesicles from adrenal medulla. Two forms of acetylcholinesterase, a membrane bound form as well as a soluble form, were found within these vesicles.

Insecticidal Terpenes From the Essential Oils of Artemisia nakaii and Their Inhibitory Effects on Acetylcholinesterase

Frontiers in Plant Science, 2021
Essential oils (EOs) are often the source of insecticidal substances of high efficiency and low toxicity. From gas chromatograph-mass spectrometer, column chromatography, and nuclear magnetic resonance spectra analyses, twenty terpenes were identified ...

Intracellular mechanisms underlying the nicotinic enhancement of LTP in the rat dentate gyrus [PDF]

, 2008
We have previously shown that activation of nicotinic acetylcholine receptors (nAChRs) enhanced long-term potentiation (LTP) in the rat dentate gyrus in vitro via activation of α7 nAChR. In the present studies, mechanisms underlying the acute and chronic
