A comparative assessment of the analytical capabilities of a tensoresistive biosensor based on muscarinic acetylcholine receptors and a potentiometric choline sensor was performed. It was found that the receptor biosensor is promising for the determi

It is shown that suboccipital injection of 100 micrograms of the gexapeptide GLLDLK (the fragment of endogenous peptide--the inhibitor of diazepam binding) modified (for 1-3 days) the emotionally conditioned behaviour of the rats (the test of "emotio

The properties of aminostigmine in comparison with those of other carbamate inhibitors of cholinesterases have been studied in vitro using potentiometric titration and Ellman methods. The bimolecular constants of the inhibition rate of acetyl-, butyr

Studies have been made on enzymic hydrolysis of p-nitrophenylacetate (p-NPhAc), n-nitrophenylbutyrate (p-NPhBu) and indophenylacetate (IPhAc) by carboxylesterase (CE) from mouse blood plasma and liver as well as from caterpillar of the cotton worm ha

Decarbamylation rate of membrane-bound methyl- and dimethyl-carbamylated acetylcholinesterase of human erythrocytes and bovine brain is reliably 1.1-1.6 times lower than that of the soluble enzyme. Such reversible inhibitors as tacrine (of non-compet

The experiments carried out present the evidence of acetylcholinesterase activity of Wistar rat lymphocytes. It was shown that splenocytes and thymocytes had significantly different levels of the enzyme activity. Peroral administration of phosphor-or

Catalytic properties of human blood erythrocyte acetylcholinesterase and horse blood serum butyrylcholinesterase immobilized and nonimmobilized in the gelatin membrane have been comparatively studied. Cholinesterase immobilization induces an increase

Physostigmine and neostigmine methylsulphate are shown to be the most strong inhibitors of acetylcholine esterase of human erythrocytes. The action of baigon is less pronounced and pyrimor is characterized as the weakest inhibitor. No differences are

Immobilization of meat fly head cholinesterase in gelatin membrane essentially increases the enzyme stability and changes its kinetic characteristics: the Michaelis constant and maximum velocity of acetylthiocholine hydrolysis and also biomolecular v
