The present study investigates the antioxidant, anticancer, anticholinesterase, anti-genotoxic activities and phenolic contents of flower, fruit and seed methanol extracts of Hypericum retusum AUCHER. The amounts of protocatechuic acid, catechin, caffeic acid and syringic acid in methanol extracts were determined by HPLC. Total phenolic content of H. retusum seed extract was found more than fru...

OBJECTIVE Food contributes in measurable body burden of the widely used organophosphate pesticides. We designed a randomized controlled open label trial in Mashhad University Hospital in Iran, to study the possible alterations in cholinesterase activity resulting from consuming market melon known to be exposed to diazinon. PATIENTS AND METHODS Fifty-three young healthy volunteers were recruit...

Alzheimer disease is characterized by a loss of cholinergic neurons in the basal forebrain and a decrease in acetylcholine levels. Currently, cholinesterase inhibitors, drugs that act by inhibiting the enzyme responsible for the hydrolysis of acetylcholine, are the only therapy for the treatment of Alzheimer disease approved by the Food and Drug Administration. The cholinesterase inhibitors hav...

The organophosphorus and carbamate insecticides inhibit cholinesterase, causing an increase of acetylcholine at neuromuscular junctions. Toxicosis due to anticholinesterase compounds can be diagnosed by finding depressed cholinesterase activity in the blood, brain, and/or retina. Cholinesterase activity < 50% of normal has been associated with significant exposure to an anticholinesterase agent...

BACKGROUND Cholinesterase inhibitors are commonly used to treat dementia. These drugs enhance the effects of acetylcholine, and reports suggest they may precipitate bradycardia in some patients. We aimed to examine the association between use of cholinesterase inhibitors and hospitalization for bradycardia. METHODS AND FINDINGS We examined the health care records of more than 1.4 million olde...

Abstract Background Cognitive impairment mainly affects learning and problem solving abilities of the person. Traditional medicines, due to fewer side effects, more efficacy lesser cost are still choice treatment in India. The main objective present study is explore nootropic potential ethanol extract Elettaria cardamomum Maton fruits. was conducted by using exteroceptive behavioral models like...

The current research aimed to determine and report in vitro antioxidant, antimicrobial, antibiofilm, cytotoxic, anti-cholinesterase, anti-diabetic properties the stability of major component basic oil Thymbra spicata var. through different phases as theoretically. Essential exhibits potential biological activities because multiple components it contains.In research, evaluation essential antioxi...

We report a two-day-old infant who had a period of apnoea lasting six hours following the intravenous administration of succinylcholine (Sch). The results of her plasma cholinesterase level and dibucaine number indicate a congenital absence of plasma cholinesterase (PChE) enzyme, although both parents and siblings had normal cholinesterase levels and dibucaine numbers. This is believed to be th...

Serum pseudocholinesterase activity in pregnant women was assayed spectrophotometrically using either propionylthiocholine or suxamethonium as substrate. All patients had a normal phenotype as indicated by normal dibucaine and fluoride numbers. However, the mean cholinesterase activity was lower than in the general population. There was a negative correlation between cholinesterase activity and...

Serum cholinesterase concentrations were measured in 181 patients in chronic renal failure. Significant differences in cholinesterase concentrations were not found in patients undergoing dialysis and changes appear to be independent of the method of treatment used. Clinical experience with suxamethonium to facilitate tracheal intubation was satisfactory in 80 patients undergoing renal transplan...
