Improvement of an analytical method on 6-benzylaminopurine (BAP), a plant growth regulator, and a firstgenerationsynthetic cytokinin for agricultural commodities wasundertaken. Analytical method for BAP in the agriculturalcommodities by gas chromatography in cooperation with nitrogenphosphorousdetector (NPD) was adopted. BAP was extractedwith acetone in all samples followed by the ion-associatedpartitioning method. Vapor pressure of BAP was increased by Nmethylationwith iodide methane [BAP→6-Benzylamino-Nmethylpurine(BAMP)]. Finally, N-methylated BAMP was separatedwith ethylacetate. The quantitation was done by GC using NitrogenPhosphorous Detector with DB-608, a moderate polarity columnunder the temperature-rising condition. The standard calibrationcurve presented the linearity of correlation coefficient (r2)>0.9999,analyzed from 0.2 to 4mg/kg. The limit of quantitation in agriculturalcommodities showed 0.05 mg/kg. The average recoveries of intraandinter-day experiments ranged from 70.4 to 103.5% and 70.3to 105.6%, respectively. The repeatability and reproducibility forintra- and inter-day measurements expressed as a relative standarddeviation (RSD) was less than 10.7 and 8.3%, respectively. Therefore, our newly established analytical method for BAPresidue in agricultural commodities was applicable to the nationwidepesticide residues monitoring program with the acceptablelevel of sensitivity, repeatability and reproducibility.

This study was carried out to investigate the effects of insulin on the CNS neurotransmitters in rats. Streptozotocin(STZ: 65mg/kg) was administered intravenously to sprague-Dawley rats,and after 5 weeks, insulin was injected for 10 days. The concentrations of norepinephrine, dopamine, 5-HT and 5-HIAA in whole brain were measured with High Performance Liquid Chromatoraphy-Electrochemical Detector(HPLC-ECD). 1. Level of norepinephrine was significantly increased in STZ-induced diabetic group compared with the control group(P<0.01). It was significantly decreased by the insulin treatment(P<0.05). 2. Level of dopamine was significantly increased in STZ-induced diabetic group compared with the control group(P<0.01). However, it was significantly decreased by the insulin treatment(P<0.001). 3. Level of serotonin was significantly increased in STZ-induced diabetic group compared with the control group(P<0.01). It was also significantly increased in insulin-treated group(P<0.001). 4. Level of 5-hydroxyindoleacetic acid was significantly increased in insulin-treated group compared with the control group(P<0.001). It was also significantly increased by the insulin treatment in comparison with STZ-induced diabetic group(P<0.01).

Since the last part of the 20th century, some healthy people have widely used central nervous system stimulants as cognitive enhancers and this phenomenon has become not only a social issue but also an important academic issue. When some scholars, especially neuroethicsts seek to legalize the cognitive enhancers used by healthy adults, there has been a huge debate over legalizing cognitive enhancement. Critics on cognitive enhancement point out five ethical problems if cognitive enhancement would be allowed by the pharmaceutical authority and widely spread in a western society. First, cognitive enhancement has a safety problem and could cause various side effects, addiction, and cognitive tradeoff. Second, cognitive enhancement is morally undesirable because it is unnatural. Third, cognitive enhancement before the exam might be cheating. Forth, cognitive enhancement would cause social inequality and thus widen cognitive gap between riches and poors. Fifth, if cognitive enhancement would be allowed and widely spread among our society, many people might face pressure to take cognitive enhancers for winning the competition or doing their work well. However, proponents on cognitive enhancement argue that these ethical concerns are exaggerated or will be resolved near in the future. They also argue that together with discussing cognitive enhancement, the evidence-based research on cognitive enhancement should take place and this would clearly reveal the risk and benefit of cognitive enhancers.
