Abstract:ObjectiveTo estimate butyrylcholinesterase (BChE), phosphodiesterase (PDE), thiols and cerulopalsmin by non – invasive means in saliva a of subjects (both cases and controls) and correlated to their hearing sensitivity.MethodsTotal of 13 subjects participated in this study. Among them 7 were having auditory neuropathy and 6 were healthy controls. Unstimulated saliva (10 ml) was collected from each participant. Ceruloplasmin, thiols, phosphodiesterase and pseudocholinesterase were estimated by colorimetric method in the salivary samples.ResultsSalivary BChE and PDE levels were marginally elevated and protein thiols were marginally decreased in cases as compared to that of controls. Salivary ceruloplasmin was significantly decreased (p = 0.022) in cases as compared to that of controls.ConclusionsSaliva can be used as a potential noninvasive tool for evaluation of disorders.
