Therefore, van der Waals' interactions between acetylcholinesterase and these drugs are stronger than those between butyrylcholinesterase probably due to a small active site gorge and a significant peripheral anionic site for acetylcholinesterase.
      
Novel 5-substituted esters and homologous ester and amido derivatives of 4,5 dihydro-3,3-diethyl-2(3H)-furanone were synthesized and evaluated for anticonvulsant activity in rodents and for affinity to a site on the GABAA receptor complex ([3H]TBOB).
      
The results showed that these compounds are capable of important interactions with the NNRT binding site, which encouraged us to submit them for biological assay.
      
From these data, it may be deduced that the administration of high concentration of 18-methyl norethindrone can displace ketoprofen from its secondary binding site.
      
This work attempts to calculate the binding-site number using fluorescence spectroscopic method with bovine serum albumin (BSA) and Indo-1 as protein and ligand models, respectively.

In accordance with the different conditions of habitat form, the principle of right species in tbe right site and the rational composition of plantation, the plant percent is promoted. 2、Based upon the conditions of climate, topography and soil, such three main factors as the amount of salt in soil, the water level of soil and the texture...

1、The most important point of reforestation in the saline and alkaline soil dis- trict is, first of all, to understand the conditions of the habitat form of planting area. In accordance with the different conditions of habitat form, the principle of right species in tbe right site and the rational composition of plantation, the plant percent is promoted. 2、Based upon the conditions of climate, topography and soil, such three main factors as the amount of salt in soil, the water level of soil and the texture of soil may be used as references in classifying the conditions of habitat form. The salt con- tent is divided into four groups: less than 0.3%, 0.3--0.5%, 0.5--1% and more than 1%; the water level of soil is classified into two classes: one is more than I meter, other is less than 1 meter; the texture of saline soil is grouped into three classes: heavy clay, sandy loam-clay loam, light loam-medium loam. Total in all there are eleven conditions of habitat form. 3、On the most especially heavy saline soil (the salt content is more than 1%) no reforestation is avaitable or plant Tamarix juniperina, Populus euphra- tica after the soil is transformed into less salted. On the heavy saline soil (the salt content is more than 0.5--1%) plant Tamarix juniperina, Populus euphratica and Populus canadensis. On the favorable saline soil (the salt contlnf is 0.3- 0.5%) Tamarix, Amorpha fruticosa, Poplus euphratica, Populus canadensis, Ulmus pumila, Salix mastudana, Elaeagnus erispa, Fraxinus americana, Robinia pseudo-acacia may be planted. On light Ealine soil (the salt contlnrt less than 0.3%) Aitan- thus altisslma, Ziziphus jujub, Morus alba, Phellodendron amurense, Thuja orientalis may be panted besides those species mentioned above.

A serious damage was done to the shade trees of Nanking City from typhoon in fall of 1962. It was found that the degree to which the shade trees were damaged was closely re-lated to (1) the characteristics of species such as crown structure, stem form, root system, resistance to excessive water and susceptibility to insects or pests; (2) the environment of plant-ing site such as direction and strength of wind, drainage and soil conditions; and (3) the plant-ing and management such as age and quality of seedlings,...

台风对行道树的影响与树种、立地条件和人为经营措施等多种因素有关。行道树风害的表现形式有风伤、风折、风歪和风倒四种。调查结果表明:枝叶风伤比较普遍,力枝风折仅占少数,主干风歪和风倒发展不平衡。受害比较严重树种包括英桐、刺槐和加杨等。树种的抗风能力,随空间和时间的转移而变化,因此结合不同的立地条件和城市特点来选择适宜的行道树种,具有很大的实践意义。外界环境因子对行道树风害的作用,实质上反映出是一种风、水、土的综合影响。我们认为在目前情况下,排除积水、改良栽植点上的土壤母质状况是防止行道树遭受风害的主要途径。
