Substance concentrations of plasma cholinesterase (EC 3.1.1.8) were measured in 94 healthy individuals without occupational exposure to known inhibitors (six samples from each individual). Immunoreactive cholinesterase substance concentrations showed an inter-individual variation corresponding to CVtotal = 22% (mean: 5.01 mg/l, SD: 1.11 mg/l). Intra-individual variations of immunoreactive choli...
aquatic animals are important resources for extraction of valuable compounds such as enzymes. in this study, lipase was extracted from the intestine of rainbow trout. samples were defatted with acetone several times; ammonium sulphate (60%) was used for precipitation followed by ultrafiltration for concentrating the samples. the final purification of the enzyme was performed by passing of the s...
A radiometric method has been used on preparations of intact ocular tissue to dissociate the effects of surface cholinesterase from intracellular enzymes. This method provides a technique to determine the effects of surface enzyme potentiation or inhibition, and may be helpful in evaluating the degree of surface enzyme inhibition with pharmacologic response. Surface cholinesterase activity was ...
ABSTRACT The present study was carried out to investigate the effect of benazepril on corneal permeation in goat cornea and its effect on experimentally induced acute and chronic glaucoma in rabbits. Acute glaucoma was produced by i.v. infusion of 5% glucose (15ml / Kg) in rabbits, whereas chronic glaucoma was induced by injection of alpha-chymotrypsin into posterior chamber of rabbit eye. We s...
Background: This study was devoted to assessing the inhibitory potential of acetone, methanol, and ethanol extracts of Acroptilon repens against disease-associated enzymes, as well as their antioxidant/antibacterial activity and phytochemical composition. Methods: Comparative assessment using various antioxidant evaluation methods, including ferric reducing antioxidant power, scavenging ability...
A series of agarofuran compounds isolated from Chilean Celastraceae were evaluated in vitro for their cholinesterase inhibitory activities by UV spectroscopy.
Background and objectives: Alzheimer’s disease (AD) is characterized as the most prevalent age related neurodegenerative disease along with cognitive impairment in elderly people. Most of therapeutic treatments for AD have dedicated to the inhibition of cholinesterase (ChEs) to increase the level of acetylcholine (ACh) in the cholinergic synaptic cleft. Acetylcholinesterase (AC...
In 1986, Whittaker wrote ‘Churchill-Davidson’s editorial entitled “The succinylcholine story” in 1963, highlighted probably for the first time in the UK, the role of serum protein polymorphism in drug sensitivity’ [1]. Following a series of detailed family studies, in 1959 Kalow [2] concluded that individuals who had prolonged apnoea following succinylcholine administration were homozygous for ...
