Propofol induced Cl- currents at concentrations of 10-5 and10-4 M, which were sensitive to picrotoxin and, to a lesserextent, to strychnine. Propofol (10-6 M) enhanced -aminobutyricacidA (GABAA; 10-6 M)-induced current synergistically. Moreover,propofol (10-5 and 10-4 M) significantly increased the decaytime of evoked-inhibitory postsynaptic currents, which suggestsa postsynaptic modulation of GABAA receptors.

In the hydroxylation of phenol with H〓O〓 in the presence of Ti-ZSM-5, water is best solvent. It produces catechol and hydroquinone simultaneously, and catechol/hydroquinone ratio is approximately 0.85. The results show H〓O〓 utilization ratio increase 14%, when nonoxidizable weak acid HAc is added into the reaction system. Under the conditions of Ti-ZSM-5 as catalyst, phenol/H〓O〓 ratio being 10, a little HAc, temperature 75℃, reaction time 6h, H〓O〓 utilization ratio reaches 74. 6mo1% in the reaction.

对Ti-ZSM-5催化苯酚羟基化的研究结果表明，水是最好的溶剂，羟基化有邻、对苯二酚两种产物，并且邻苯二酚/对苯二酚摩尔比可维持在～0.85左右；向反应体系中加入非氧化性弱酸性助剂HAc时，H〓O〓有效利用率较未加入助剂时可提高14mol%；当催化剂用量为8g/100g苯酚、苯酚/H〓O〓比为10、反应温度75℃、添加少量HAc的条件下，反应6h后，H〓O〓有效利用率可达74.6mol%。

We also studied their inhibition on H2O2,UV-induced hemolysis of RBC. Sodium paeonol sulfonate was used as keep-freshing agent in tomato storage and vitamin C content, brix, acidity, weight loss, membrane permeability, soluble protein content, SOD andPOD activity was determined. The results were as follows: Paeonol and sodiumpaeonol sulfonate had remarkably inhibitory effects on Xanthmonas oryzaepv.oryzicda,Pseudomonas solanacearum Smith, Phyllosticta mali Pril.et Delac.and Rhizoctonia solani Kuhn.

在生物学活性方面，检测了丹皮酚及丹皮酚磺酸钠对植物病原菌的抑制作用，测定了其清除超氧阴离子自由基(O_2~-)、羟自由基的活性及对过氧化氢(H_2O_2)和紫外线诱导红细胞溶血的影响，并用丹皮酚磺酸钠对樱桃番茄进行了保鲜研究，测定贮藏期间番茄的维生素C含量、糖度、酸度、失重率、膜透性、可溶性蛋白含量、超氧化物歧化物及过氧化物活性等。

Wood could be liquefied into soluble reactive intermediates, which could further reactedwith phenol or by themselves. Phenolation and recondensation were a pair of competingreactions. Decomposition, phenolation and recondensation dominated the whole liquefactiondynamic process and determined the structural characteristics of liquefied wood.

4木材组分在液化过程中逐渐分解为较小分子量的液化中间产物，这些中间产物的活性较高，可以继续与苯酚或互相之间发生酚化或再缩聚反应，酚化反应和再缩聚反应是一对互相竞争的反应，降解、酚化和再缩聚三种反应主宰着整个液化动力学过程，也决定着液化产物的结构特征。

Modern medicine to prove: camellia oil rich in oleic acid, and linoleic acid and linolenic acid content of the proportion is also larger and reasonable, and tea oil contains olive oil does not have a specific physiologically active substances, such as: camellia saponin, camellia saponin, tea polyphenols phenol, etc., including: the role of camellia glucoside has a strong heart, camellia saponin with thrombolytic effect, and tea polyphenols have lower cholesterol levels, the chemical prevention of cancer and many other effects, can prevent various cardiovascular and cerebrovascular diseases; Moreover, tea oil free can cause human carcinogen aflatoxin, as well as erucic acid, saponin, and gossypol and other harmful substances, the elderly can benefit from the consumption of tea oil, tea oil is therefore referred to as longevity oil.

现 代医学证明：山茶油中富含油酸，并且亚油酸、亚麻酸含量比重也较大且合理，茶油中含有橄榄油所没有的特定生理活性物质，如：山茶甙、山茶皂甙、茶多酚等，其中：山茶甙有强心作用，山茶皂甙有溶血栓作用，而茶多酚具有降低胆固醇、化学预防肿瘤等多种作用，能预防各种心脑血管疾病；而且，茶油不含可引起人体致癌的黄曲霉素以及芥酸、皂素和棉酚等对人体有害的物质，老年人可因食用茶油而得益，所以茶油被称为&长寿油&。
