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 ...

Organophosphate chronic toxicity has been evaluated in this study. Biological screening for organophosphate insecticide-exposed workers is mostly recommended for mixers, loaders, formulators and spraymen. We have studied 17 occupationally exposed persons to pesticides. Using Ellman's colorimetric method, their plasma cholinesterase activities have been measured. Results show that the appear...

The most prevalent illnesses that affect the liver are viral infections; when cell is destroyed by viruses, it loses its function and of body's processes compromised. primary source serum cholinesterase. Therefore, cholinesterase can be used as a predictive biomarker for liver's synthetic capability. This study aims to evaluate in patients with hepatitis B virus (HBV) or C (HCV). was conducted ...

Background: Chronic liver disease in the clinical context is a process of that involves progressive destruction and regeneration parenchyma leading to fibrosis cirrhosis1. The serum cholinesterase mainly synthesized it released into blood, which reduced dysfunction due synthesis, marked reduction restoration synthesis with hepatocyte recovery suggest activity might be more specific marker than ...

Background and Objective: Depression is a common disorder, especially in developed countries. Functional changes of cholinesterase are involved in pathogenesis of some brain disorders. Until now, exact association of these changes with depression has not been determined. This study was conducted to evaluate the changes of serum cholinesterase in lipopolysaccharide (LPS)-induced model of depress...

Alzheimer’s disease (AD) causes dementia and continuous damage to brain cells. Cholinesterase inhibitors can alleviate the condition by increasing communication between nerve cells reducing risk of dementia. In an effort treat disease, we synthesized flurbiprofen-based diamines (1,2 diaminoethane 1,3 diaminopropane) Zn(II), Cu(II) metal complexes characterized them single-crystal X-ray analysis...

Two families segregating for the atypical (E1a) allele at cholinesterase locus 1 are described. Unusual results for dibucaine inhibition led to the recognition of a new allele (E1k) also segregating in these families. The enzymatic and immunological data are consistent with the hypothesis that E1k causes reduction of 'usual' (E1u) molecules by about 33%. Whether the reduction of E1u caused by E...

Cognitive deficits are commonly associated with maintenance electroconvulsive therapy (ECT). Treatment of these cognitive deficits is important but difficult. Cholinergic pathways are involved in these side effects, and donepezil, a cholinesterase inhibitor, may be useful for improvement of cognition. In this case report, we describe for the first time successful use of donepezil in treating co...

Specimens of plasma from 51 agricultural workers were divided into several portions for freezing and storage. Periodic assays (in duplicate) for cholinesterase activity in each specimen were compared with the initial values obtained on each fresh, unfrozen specimen. Freezing and/or thawing results in loss of approximately 30% of the plasma cholinesterase activity. It is not possible to use divi...
