If, relative to isoflurane, cyclopropane minimally increases GABA-induced chloride currents at any GABAA receptor subtype, the present data for MAC are consistent with the notion that GABAA receptors do not mediate the immobility produced by inhaled anesthetics.

如果，相对於异氟烷而言，环丙烷在任何γ-氨基丁酸 A 受体的亚体上都是极微弱地增加γ-氨基丁酸介导氯电子流的作用，那麼现在关於 MAC 的资料就和γ-氨基丁酸 A 受体不是吸入性麻醉药产生的抑制作用的介导者这一概念一致。

OBJECTIVE: To separate the available composition that inhibits immunity form Ephedra sinica Stapf , and to study its effects on experimental autoimmune thyroiditis and its mechanism.

目的：从麻黄中分离出具有免疫抑制作用的有效部位，并研究其对小鼠实验性自身免疫性甲状腺炎的治疗作用及机理。

The activation by monovalent ions is at least partially due to removal of the inhibition by an excess of Mg〓.

一价阳离子的激活作用至少部分是源于对高浓度镁离子抑制作用的拮抗效应。

During these years (1997-2000) in the research area of annonaceous acetogenins 5 natural products and a number of chiral-pure analogs of annonaceous acetogenins have been synthesized using sugars as the starting materials. Their high activity and selectivity against cell line of colon tumor and a relationship between activity and configuration have been found too. In the respect of inhibitor of sialidase two new methodologies for the synthesis of chiral-pure 3-deoxy-ulosonic acid using hetero-Diels-Alder reaction or asymmetric propargylation as the key reaction were developed. On the topic of anti-leukemia marine natural product clavulactone a synthetic method based on the free radical cyclization and starting from sugar has been developed. In other title of PKC inhibited agent sphingosine a new synthetic route with SN2' as the key reaction has also been disclosed.

项目期间（1997-2000）在番荔枝内酯方面从糖出发合成了五个天然产物和一批手性纯的类似物，它们对肠癌细胞有很高的活性和选择性，并与构型有关；在唾液酸酶抑制剂方面发展了二类全新手性纯高碳糖的合成方法－杂原子D－A反应或丙炔基不对称加成为关键的反应；抗白血病海洋天然产物群柱虫内酯方面研究了由糖出发和自由基环化反应的合成方法；对PKC 起抑制作用的鞘氨醇方面也开创了新的合成途径－由糖出发并以SN2'反应为关键反应。

The results indicated that some ingredients of those Chinese herbal medicines had some degree of inhibitory effect, and the n-butanol extract from Alisma orientalis Juzep had more activity.

经过筛选发现：车前子、熟地黄、泽泻、川牛膝均存在某些对5α-还原酶有一定的抑制作用的提取部位，其中以泽泻的正丁醇提取部位抑制活性最强。

We have found that plumula nelumbinis, euphorbiae fischerianae and euphorbiae can inhibit the proliferation of rat lung fibroblast. Plumula nelumbinis is the best drug with most effective and little cytotoxic action.

I热川川川川川川~蔗选，寻找到了莲子心、狼毒、千金子、这三种对大鼠肺成纤维细胞有抑制作用的中草药，其中效果最佳、细胞毒作用最小的为莲子心提取物。

The mixture of broad bean and wheat flour during fermentation was used to screen antagonistic bacteria against aflatoxigenic Aspergillus flavus. A strain L4 with strong antifungal activity against the aflatoxin-producing Aspergillus flavus was selected using broadbean agar medium.

从自然发酵的豆瓣中筛选出对产毒黄曲霉菌的生长及其毒素合成均有抑制作用的细菌，在蚕豆天然培养基上利用菌落对峙实验初筛和滤纸片复筛得到1株有较高抑制产毒黄曲霉活性的菌株L4。

Meanwhile, the activation of caspase-3 could be found increased in ClearCa-6 with lower expression of XIAP, but not in ClearCa-2 with higher expression of XIAP when exposed to various apoptotic inductions.

4意外发现Nitrite存在下UVA的照射可引起Caspase-3活性的抑制，并证明此抑制作用的直接机制是UVA使Nitrite在光解作用中释放NO，使Caspase-3受到亚硝化修饰而丧失活性。
