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.
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 ...
Some elements of the cholinergic crisis can be reversed with antimuscarinic drugs like atropine or diphenhydramine, but the most dangerous effect — respiratory depression, cannot. [ 6 ] The neuromuscular junction, where the brain communicates with muscles (like the diaphragm , the main breathing muscle), works by acetylcholine activating ...
Bradycardia; Hypertension (high blood pressure); Allergic reactions (e.g. dyspnoea (shortness of breath), bronchospasm, wheezing, angioneurotic oedema) Anaphylaxis; Changes in appetite
Main symptoms of multiple sclerosis Symptoms and findings in multiple sclerosis. Multiple sclerosis can cause a variety of symptoms varying significantly in severity and progression among individuals: changes in sensation (hypoesthesia), muscle weakness, abnormal muscle spasms, or difficulty moving; difficulties with coordination and balance; problems in speech or swallowing (), visual ...
Neurotoxic effects have also been linked to poisoning with OP pesticides causing four neurotoxic effects in humans: cholinergic syndrome, intermediate syndrome, organophosphate-induced delayed polyneuropathy (OPIDP), and chronic organophosphate-induced neuropsychiatric disorder (COPIND). These syndromes result after acute and chronic exposure ...
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.
These include acamprosate or naltrexone in the treatment of alcoholism, or methadone or buprenorphine maintenance therapy in the case of opioid addiction. [26] Exposure to psychoactive drugs can cause changes to the brain that counteract or augment some of their effects; these changes may be beneficial or harmful. However, there is a ...
