Sepsis is associated with neuronal damage and cognitive impairment, with the participation of pro-inflammatory cytokines and oxidative-nitrous stress. It is known that activated microglia plays a vital role in neuro-inflammation and neuro-degeneration. Thus, the objective of this study was to

1. In cats under ether or hexobarbitone anaesthesia the auriculotemporal nerve was cut near the parotid gland on one side and 12-20 mm more proximally on the other. After 22-64(1/2) hr the cats were anaesthetized with chloralose and the parotid ducts cannulated. Degeneration secretion of saliva

The pressure response of the rat urinary bladder to electrical stimulation of the pelvic nerve at a low stimulation frequency was found to be almost completely atropine resistant. However, the response to stimulation of the degenerating pelvic nerve 20-30 h after section of the nerve

Studies in humans and rodents support a role for muscarinic ACh receptor (mAChR) and nicotinic AChR in learning and memory, and both regulate hippocampal synaptic plasticity using complex and often times opposing mechanisms. Acetylcholinesterase (AChE) inhibitors are commonly prescribed to enhance

Organophosphorus-ester induced delayed neurotoxicity (OPIDN) is a neurodegenerative disorder characterized by ataxia progressing to paralysis with a concomitant central and peripheral, distal axonapathy. Diisopropylphosphorofluoridate (DFP) produces OPIDN in the chicken that results in mild ataxia

Changes in the blood content of a 1 cm(2) portion of the intact rabbit's ear were studied with transillumination and a photocell. Stimulation of the post-ganglionic sympathetic nerves produced a decrease in blood content, attributable to vasoconstriction, followed by an increased blood content,

Carnitine is a natural substance that acts as a carrier of fatty-acids across the inner mitochondrial membrane for subsequent beta-oxidation. Acetyl-L-carnitine is the acetyl derivative of L-carnitine that has been shown to possess a slight cholinomimetic activity. Its success in sports medicine is

Cynomolgus monkeys underwent unilateral PRP with xenon arc or argon or krypton laser light, employing burn intensity, size, spacing, and topography analogous to standard clinical (eg, Diabetic Retinopathy Study) treatment. Shortly thereafter, accommodative responsiveness to topical eserine and

Cynomolgus monkeys underwent unilateral panretinal scatter photocoagulation (PRP) and/or nasal and temporal horizontal retinal meridional photocoagulation (HRMP) with xenon arc or argon or krypton laser light. Shortly thereafter, in the PRP-treated eyes, accommodative responsiveness to topical

Rabbits were immunized versus either an acetylcholinesterase- or a cholinergic receptor-rich fraction isolated from the electric organ of Torpedo marmorata. In both groups of animals we obtained a production of specific antibodies detected by immunodiffusion without cross reaction for the two

Acetylcholinesterase (AChE) has been known to be the target of organophosphorous and carbamate insecticides. Only a single AChE, however, existed in insects and was involved in insecticide resistance, recently another AChE is reported in mosquitoes and aphids. We have cloned cDNAs encoding two ace

Cynomolgus monkeys underwent unilateral ciliary ganglionectomy (CG) and/or posterior ciliary neurectomy (PCN). The ciliary muscle was functionally denervated, as evidenced by loss of choline acetyltransferase activity, loss of the accommodative response to topical eserine and electrical stimulation

Septic encephalopathy is associated with rapid deterioration of cortical functions. Using magnetic resonance imaging (MRI) we detected functional abnormalities in the hippocampal formation of patients with septic delirium. Hippocampal dysfunction was further investigated in an animal model for
