Increased plasma adrenalin (A) levels following arecoline in normal subjects and patients with multiple system atrophy (MSA) may result from nicotinic adrenal stimulation. Lack of this response in patients with pure autonomic failure (PAF) is consistent with peripheral sympathetic dysfunction. The m Approximately 600 million people worldwide practise the carcinogenic habit of betel nut/quid chewing. Carcinogenic N-nitroso compounds have been identified in saliva or urine of betel chewers and the betel alkaloid arecoline in hair from habitual betel quid chewers. However, the pharmacokinetic para

It is an odourless oily liquid volatile in steam, miscible with most organic solvents and water, but extractable from the latter by ether in presence of dissolved salts. The salts are crystalline, but usually deliquescent Arecoline, a major alkaloid in areca nuts, is involved in the pathogenesis of oral diseases. Mammalian taste buds are the structural unit for detecting taste stimuli in the oral cavity. The effects of arecoline on taste bud morphology are poorly understood. Arecoline was injected intraperitoneally (IP) into C57BL/6 mice twice daily for 1-4 weeks Untreated oral KB carcinoma cells are cuboid and polygonal in appearance with clear intercellular space (Figure 3d). Exposure of KB cells to 0.4 mM of arecoline for 24 h led to retraction and rounding in some sensitive cells. On exposure to 0.8 mM of arecoline, KB cells seemed larger and lost sharp intercellular space
The transitions of m/z 156.2-->53.2,m/z 142.2-->44.2 and m/z 172.2-->60.2 were selected for Arecoline, arecaidine and Arecoline N-oxide, respectively. The method was linear over the concentration range of .5-100ng/mL for Arecoline, 5-5000ng/mL for arecaidine and Arecoline N-oxide with no carry-over effect. The accuracies and intra- and inter. . Arecoline Hydrobromide is an arecoline salt of hydrobromic acid generally used in removing parasites from the dog's intestine. It has a strong parasympathomimetic action. Arecoline and other muscarinic receptor agonists have been shown to improve learning and memory and may prove to be useful in treating dementia The response surface methodology (RSM) including polynomial equations has been used to design an optimal patch formulation with appropriate adhesion and flux. The patch formulations were composed of different polymers, including Eudragit RS 100 (ERS), Eudragit RL 100 (ERL) and polyvinylpyrrolidone K30 (PVP), plasticizers (PEG 400), and drug. In addition, using terpenes as enhancers could. Involvement of ionotropic glutamate receptors in the appearance of arecoline tremor in mice.
