For long-term treatments, the rat administered daily by gavages for six weeks, the results of OGTT showed that guava fruit water or alcohol extracts could reduce the plasma glucose level in the diabetic Wistar rats, however there was on significant difference in insulin level among all tested groups. The results of carbohydrate metabolism showed diabetic Wistar rats administered with 200 or 400 mg/kg BW of guava fruit water or alcohol extracts could decrease more than 15% glucose-6-phosphatase and fructose-1,6-bisphosphatase activities, and it also increase more than 12% glucose-6-phosphate dehydrogenase activities to reduce inhibitory hexokinase from reducing glucose-6-phosphate level.

在醣类代谢方面，实验结果发现糖尿病鼠灌食番石榴果实水及乙醇萃取物六周后，肝脏醣质新生作用中丙酮酸合成肝醣之关键酵素glucose-6-phosphatase及fructose-1，6-bisphosphatase的酵素活性会降低15%以上；另一方面肝脏glucose-6-phosphate dehydrogenase酵素活性则明显增加12%以上，并造成glucose-6-phosphate浓度减少，进而降低其对hexokinase的抑制(因为hexokinase受其代谢产物G-6-P的浓抑制)，因此加速肝脏葡萄糖的糖解作用。

Simultaneously, the activity and coding gene expression of ribulose 1, 5-bisphosphate carboxylase, phosphoenolpyruvate carboxylase, and glycollic oxidase all decrease in two rice accessions under low potassium supply while significant decrease in non-allelopathic rice "Lemont".

水稻光合作用相关酶的分析结果表明，低钾条件下核酮糖－1，5-二磷酸羧化酶、磷酸烯醇式丙酮酸羧化酶和乙醇酸氧化酶的活性及其基因表达强度均降低，但化感水稻&PI312777&的下降幅度显著小于非化感水稻&Lemont&。

The product has green-yellow fluorescence at excitation wavelength of 355 nm and emission wavelength of 478 nm, and the fluorescence intensity could be enhanced in the presence of acetone.

三、流动注射在线氧化荧光法测定氯普噻吨的的研究利用在硫酸介质中二氧化铅可使无天然荧光的氯普噻吨氧化而转变为在最大激发波长和最大发射波长分别为393nm和452nm的强荧光物质，而且丙酮对该荧光体系有强烈增敏作用的现象，建立了以醋酸纤维素固定化的二氧化铅作为固相反应器的流动注射在线氧化荧光法测定氯普噻吨的新方法。

Flow injection fluorometry for the determination of carbamazepine in pharmaceuticals and plasmaA simple, sensitive and specific spectrofluorimetric method has been developed for the determination of CBZ. The method was based on lead dioxide solid-phase reactor flow injection on-line oxidizing CBZ into fluorescent product in medium of phosphoric acid. The product has green-yellow fluorescence at excitation wavelength of 355 nm and emission wavelength of 478 nm, and the fluorescence intensity could be enhanced in the presence of acetone. The reaction conditions and experimental conditions were studied and optimized.

二、流动注射在线氧化荧光法测定卡马西平的研究利用卡马西平自身无荧光，经过氧化后可转变为在最大激发波长为355nm，最大发射波长为478nm的强荧光物质，而且丙酮对该荧光体系有增敏作用的现象，应用流动注射体系建立了以醋酸纤维素固定化的二氧化铅作为固相反应器、在磷酸介质中在线氧化荧光法测定卡马西平的新方法。
