Three kinds of explants from Cajanus cajan were used to established callus culture. Ethanolic extract prepared from five plant materials, callus from cotyledon, callus from hypocotyl, callus from root, Cajanus cajan seeds and Glycine max seeds were examined for their phenolic contents, flavonoids contents and DPPH radical - scavenging activity.

在多因素控制与诊断方面,本文将两质量诊断理论的思想应用于多因素诊断,提出了多因素选图与休图相结合以及单因素选图与休图相结合的两多因素诊断方法,指出了现有多元质量控制方法中存在的缺点,并提出了逐步诊断的思路和三用于多因素诊断的逐步诊断方法,即顺序统计量逐步诊断法、最小距离逐步诊断法和两质量逐步诊断法,然后通过统计模拟进行了分析和比较。

Only in cauchy distribution are expected value and variance non-exist. By sas programming with SQL and MACRO we solve the fit of frequency distributions of data with these distributions. Meanwhile good-of-fit test is actualized so that the bound of parameters of distribution function is dwindling until the desired accuracy is arrived. The process is executed by the circle of macro.

利用SAS的SQL和MACRO等语句编写了大量的程序,以拟合优度检验结果为标准,不断地变换八分布的参数变化范围,通过宏程序的不断循环,逐步缩小参数的范围,最后达到预先设定的标准,从而可以发现八分布中哪几分布能比较好地拟合给定的实际频数资料,我们再根据拟合优度检验的结果判断出哪分布拟合实际频数资料最好,最终获得该频数资料的最佳的理论分布函数形式。

In clinical. acetylcholinesterase inhibitors reduce the breakdown of synaptic acetylcholine, have been modestly effective in improving the cognitive deficits of Alzheimer's disease.The goal of this work is to determine enzyme kinetics and mechanisms of acetylcholinesterase and butyrlcholinesterase inhibition by five cardiovascular drugs, lovastatin, simvastatin, amlodipine besylate, nifedipine, and hydralazine hydrochloride, and two benzodiazepines, diazepam and chlordiazepoxide hydrochloride. All drugs in this study are reversible mixed-type inhibitors of acetylcholinesterase and butyrylcholinesterase. The pKi values for acetylcholinesterase and butyrylcholinesterase inhibition by the cardiovascular drugs are linearly correlated with the molecular weights of the drugs with the slopes of 0.005 and 0.0021, respectively. Therefore, van der Waals' interactions between acetylcholinesterase and the cardiovascular drugs are stronger than those between butyrylcholinesterase and the drugs. This is probably due to a smaller active site gorge and a more significant peripheral anionic substrate binding site of acetylcholinesterase than those of butyrylcholinesterase.

本研究之目的系决定乙醯胆碱酯酵素和丁醯胆碱酯酵素被五心脏血管药物lovastatin, simvastatin, amlodipine besylate, nifedipine、hydralazine hydrochloride和两benzodiazepines:diazepam和Chlordiazepoxide hydrochloride的抑制作用之动力学及机转,这些药物都是乙醯胆碱酯酵素和丁醯胆碱酯酵素的可逆性、混合型之抑制剂,实验结果显示,五心血管药物对於乙醯胆碱酯酵素及丁醯胆碱酯酵素抑制之pKi值和药物之分子量呈直线之关系,斜率分别为0.005及0.0021因此丁醯胆碱酯酵素,与心血管药物间之凡德瓦作用(van der Waals' )比乙醯胆碱酯酵素与心血管药物间者弱,这可能原因是丁醯胆碱酯酵素之活性区域比乙醯胆碱酯酵素之活性区域更宽广,但丁醯胆碱酯酵素之周边阴离子区域不及乙醯胆碱酯酵素之周边阴离子区域者明显重要,由於五心血管药物对於乙醯胆碱酯酵素和丁醯胆碱酯酵素抑制之pKi值存在著线性关系表示此抑制作用系经过共同之反应机理。
