OBJECTIVES Metals such as iron are needed for physiological functions of the body. However, their excess may cause serious damage including poisoning. The effects of Fe2+ and Fe3+ ions on human plasma cholinesterase activity were investigated. MATERIAL AND METHODS Plasma were obtained (n = 24) from healthy male volunteers, and treated with five various concentrations of Fe2+ and Fe3+ ions. Ac...

Most investigations of possible metabolic aberrations in childhood schizophrenia failed to demonstrate differences between schizophrenic patients and control groups. Cholinesterase activity has net been previously reported in schizophrenic children. Similar studies with adult schizophrenics have hot been consistent, despite some reports of abnormal cholinesterase activity. The present study rep...

organophosphate (ops) compounds are widely used in intensive agriculture to improve production, protect crops and control diseases vectors. the main mechanism of toxicity of ops is the inhibition of the cholinesterase enzymes. in this study the acetylcholinestrase (ache), butyrylcholinesterase (bche) and specific acetylcholinestrase (sache) activities as potential biomarkers of exposure to ops ...

Marcz M V S ~ ~L~,XNrS have been introduced during the past decade. Of all these relaxants, succmylcholine is the only drug with a fleeting action. This short duration of action has been ascribed to a rapid enzTmatlc destruction of succinylcholine in the body ( 1, 2). The only enzyme which is known to destroy succinylchohne m man ~s plasma eholinesterase. There are several synonyms for plasma c...

background: the environmental degradation products of pesticides may enter drinking water and result in serious health problems. objective: to evaluate the occurrence of insecticides in drinking surface and ground water in dakahlyia governorate, northern egypt in 2011. methods: we studied blood samples collected from 36 consecutive patients diagnosed with pesticides poisoning and 36 tap drinkin...

Plasma cholinesterase and erythrocyte acetylcholinesterase activities have a long history of use in monitoring both workers at risk of organophosphorus pesticide (OP) exposure and in investigating accidental exposures to OPs. On account of wide inter-individual variation, the establishment of unexposed, baseline enzyme activities is necessary for accurate interpretation. This paper describes th...
