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种心脏血管药物lovastatin， simvastatin， amlodipine besylate， nifedipine、hydralazine hydrochloride和两种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，五种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，由於五种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种抑制作用系经过共同之反应机理。

The principle is based on the reversibility of a photochemical reaction accompanied by a change of coloration.

其原理是根据光化反应的可逆性伴随的染色变化。

First, the relationship between them had been up and down, but the general tendency was descending. Second, the honeymoon time was short, and it always kept states of contradictoriness. Third, the struggles sometimes showed relaxed and sometimes showed sharply. While the forms were legal. The struggle fields showed in politics, economics and thought field. Four, the crackof two sides relationship was irreversibility.

一是两方关系有起有落，总的呈下降趋势；二是实质上的蜜月时间短，多数时间处于矛盾对立状态；三是斗争时缓时烈，斗争形式一般为合法斗争，斗争领域一般在政治、经济、思想领域；四是双方关系的破裂表现出不可逆性。

There were no difference between normal children and asthmatic children in the relaxed stage in the levels of urine NAG、mALB、TRF, so we can say that the kidney damage of asthma was conversable , and we must treat carefully to avoid damaging kidney in acute attack stage of asthma.

缓解期尿NAG、mALB、TRF检测与正常组比较无明显差异，说明其肾脏损伤是可逆性的，但在发作期用药仍应注意避免加重肾损伤。
