Notice of Retraction Flow Injection Spectrophotometry Determination of Salivary alpha-Amylase for Stress Evaluation

Salivary α-amylase is a hot research area of stress; many studies have confirmed that the substance can be used as the marker of stress-related autonomic nervous system. This paper presents a fast and simple method for determination of salivary α-amylase by flow injection spectrophotometry. The cycle of a sample using this method is only 58s; this method can be automated operation with a high precision, which can avoid big differences of determination caused by improper manual control on the operation time. The established method was successfully applied to detection of salivary samples from an exercise stress test. The stress process was better monitored by this method with good reproducibility.
