Diels (contains ligustilide ＞ 70%), could markedly inhibit the contractile function of isolated uterine smooth muscle of mice in a concentration-dependent manner (the utlimate bath concentration is 1 mg/100 mL～32 mg/100 mL) whether the test sample was isolated from normal or oxytocin treated mice. It proved that angelica oil had significant anticonvulsive effect in uterine smooth muscle of mice.

当归油 (含藁本内酯 ligustilide＞70%)，用1%吐温-80助溶，无论对正常未孕离体子宫还是对经缩宫素处理的离体子宫，都可剂量依赖性(浴槽终浓度为 1 mg/100 mL～32 mg/100 mL)地抑制子宫平滑肌的收缩功能，其性质与妇痛宁滴丸相似，但作用稍强，表明其有抗子宫平滑肌痉挛作用。

The effects, of protection and treatment with, combined Ch, NaF and a trophie were significantly better than that with atropine alone. In isolated phrenic nerve-diaphragm preparation of rat, isolated jejuneal preparation of, guinea pig, and the metabolic experiment of rat liver, the results of the, assay on the rat blood ChE activity indicated that antidotal effect of NaF may be due to the antidese...

大鼠离体膈神经膈肌、豚鼠离体空肠和大鼠肝脏代谢实验及对大鼠全血胆碱酯酶活力测定的结果表明，NaF的抗毒作用可能是由于其对神经肌肉接头和/或神经节中的N受体的抗脱敏作用；而Ch则可能通过其对ChE的保护和/或加速被抑制ChE的复能，阻碍Ach到达M受体部位而发挥作用。

Along with rapid development of bio-technology, artificial chromosome doubling in vitro is the efficiency approach of producing polyploidy plants. Advances on in vitro induction of autotetraploid in plants was reviewed.

We set up an orthogonal experiment, use diclofenac sodium as drug model, detect the pemeate velocity, lag time, and transit dose accumulated in 24 hours(Q24) as index of drug action of azone, menthol and camphol using together on skin of back of unde rat on the equipment of percutaneous absorption in vitro, evaluate the contribution of transdermal enhancers by Topsis.

在离体透皮吸收装置上，采用正交试验的设计方法研究不同浓度的氮酮、薄荷醇、冰片联用对双氯芬酸钠在离体裸小鼠背部皮肤上的透皮行为，以累积透过量、渗透速率和滞后时间为药效指标，运用Topsis法评价促透效果。

METHODS AND RESULTS: Adherent platelets express substantial amounts of SDF-1 and recruit CD34+ cells in vitro and in vivo. A monoclonal antibody to SDF-1 or to its counterreceptor, CXCR4, inhibits stem cell adhesion on adherent platelets under high arterial shear in vitro and after carotid ligation in mice, as determined by intravital fluorescence microscopy.

方法和结果：在体和离体的粘附血小板表达大量SDF-1、募集CD34+细胞，在体荧光镜下可见，在小鼠颈动脉结扎后、离体条件下的动脉内高剪切应力时，SDF-1或其相应受体的单克隆抗体－CXCR4抑制干细胞粘附于血小板上。

In the present experiment, the screening techniques for salt tolerance and mutants of strawberry leaf and anther callus in vitro were studied, and primary screening system for salt tolerance evaluation was established. It was studied the sensitivity to mutagen of different strawberry cultivars and different tissues in vitro.

本试验以草莓离体叶片及花药愈伤组织为试材进行了耐盐突变体的诱变及筛选研究，初步建立了草莓耐盐突变体诱变筛选的技术体系，研究了草莓品种以及离体组织对诱变剂的敏感性，并且对不同诱变处理再生植株的耐盐性差异进行了比较。

With mature seeds of C. dayanum as explants, different media were selected to establish asymbiotic germination technique system With protocorms as materials, conservation, proliferation resumption and plant regeneration conditions were selected to establish low-temperature in vitro conservation technique system preliminarily. Mature seeds of C.

方法］以冬凤兰种子为外植体，选择不同培养基建立冬凤兰非共生萌发技术；同时利用原球茎为材料，选择低温离体保存，恢复增殖及植株再生条件，初步建立冬凤兰低温离体保存技术体系。

METHODS:①Sixty samples were randomly divided into two groups(test and contrast groups,n=30 respectively),and the sciatic nerves of the toad was isolated.Two sorts of solution(alkalinized and plain bupivacaine hydrochloride) were applied to a segent of nerve,and the amplitude of the action potential was measured.②The grouping method was the same as above.After destroying the cord above the third spinal vertebrae,two sorts of bupivacaine soultion in various concentration were injected into abdominal cavity of the toad.The leg′s flexing time was measured.

①离体坐骨神经法：取蟾蜍60只，制备坐骨神经标本，分两组，实验组和对照组各30只，测定不同浓度的两组布吡卡因对离体坐骨神经动作电位幅度的影响；②在体坐骨神经丛法：取蟾蜍60只，分组同上，破坏第三脊椎以上的脊髓后，将不同浓度的两种布吡卡因注入蟾蜍的腹腔内，测定其缩腿反射消失的时间。
