Malathion is an acetylcholinesterase inhibitor, a diverse family of chemicals.Upon uptake into the target organism, it binds irreversibly to the serine residue in the active catalytic site of the cholinesterase enzyme.
Olney's lesions, also known as NMDA receptor antagonist neurotoxicity (NAT), is a form of brain damage consisting of selective death of neurons but not glia, observed in restricted brain regions of rats and certain other animal models exposed to large quantities of psychoactive drugs that inhibit the normal operation of the neuronal NMDA receptor.
Standard treatment for nerve agent poisoning is a combination of an anticholinergic to manage the symptoms, and an oxime as an antidote. [12] Anticholinergics treat the symptoms by reducing the effects of acetylcholine, while oximes displaces phosphate molecules from the active site of the cholinesterase enzymes, allowing the breakdown of ...
Alcohol-related brain damage [1] [2] alters both the structure and function of the brain as a result of the direct neurotoxic effects of alcohol intoxication or acute alcohol withdrawal. Increased alcohol intake is associated with damage to brain regions including the frontal lobe , [ 3 ] limbic system , and cerebellum , [ 4 ] with widespread ...
Toxic encephalopathy is a neurologic disorder caused by exposure to neurotoxic organic solvents such as toluene, following exposure to heavy metals such as manganese, as a side effect of melarsoprol treatment for African trypanosomiasis, adverse effects to prescription drugs, or exposure to extreme concentrations of any natural toxin such as cyanotoxins found in shellfish or freshwater ...
Effects of anticholinergic drugs include: Delirium (often with hallucinations and delusions indistinguishable from reality); Ocular symptoms (from eye drops): mydriasis, pupil dilation, and acute angle-closure glaucoma in those with shallow anterior chamber [11] [12] [13]
The signs and symptoms of paracetamol toxicity occur in three phases. The first phase begins within hours of overdose, and consists of nausea , vomiting, a pale appearance , and sweating . [ 10 ] However, patients often have no specific symptoms or only mild symptoms in the first 24 hours of poisoning.
In humans, AChE is a cholinergic enzyme involved in the hydrolysis of the neurotransmitter acetylcholine (ACh) into its constituents, choline, and acetate. [20] Overall, in mammals, AChE is primarily involved in the termination of impulse transmission at cholinergic synapses by rapid hydrolysis of the neurotransmitter acetylcholine. [ 20 ]
