It proved that yellow-mutant belongs to the type of absence of chlorophyll; etiolation had relation to the lack of chlorophyll.The biology characteristic of the yellow-mutant cultured in vitro was investigated. The results showed that the mutant behaved etiolation character in different temperature and illumination time condition.

在离体培养条件下，探讨了桑树黄化突变体的生物学特性，发现在不同温度及光照条件下均表现黄化特征，证明该突变体叶色黄化与否与温度变化无关，不属于温敏型或光敏型叶色突变体，但突变体的黄化程度受温度影响而有一定的变化。

bFGF protected guinea pig utricular hair cells from Neomycin injury in vitro.

新霉素对离体的椭圆囊毛细胞有较强的破坏作用；bFGF对新霉素所致离体椭圆囊毛细胞的损伤有保护作用。

Results A significantly higher number of survival utricular hair cells was seen in experimental group(P＜0.05),as compared with control group.Conclusion bFGF protected guinea pig utricular hair cells from Neomycin injury in vitro.

结果 含bFGF的实验组毛细胞的存活数目显著高于不含bFGF的实验组P结论新霉素对离体的椭圆囊毛细胞有较强的破坏作用；bFGF对新霉素所致离体椭圆囊毛细胞的损伤有保护作用。

The treatment group was injected venously with 0.5 mL of TAPP-Co-NO mixed DMSO, and the control group was given with 0.5 mL of DMSO.

选取家兔离体胸主动脉环测TAPP-Co-NO对家兔离体胸主动脉环舒张作用。

In this experimental conditions, the VEC had not damnified obviously by perfusion with IECS in 4 hours. The pulmonary vascular resistance could decreased by POE1 and so vascular endolhelial cells would be protected. Mannitol not only increase osmotic pressure but also cleanse OFR. The addition of mannitol, POE1, glucose and osmotic pressure to IEC solution contributes to reduce the quantities of OFR.

2在本实验条件下所采用的IECS进行犬肺灌洗、离体保存4h之内肺血管内皮细胞无明显损伤，PGE；具有保护肺血管内皮细胞的作用；甘露醇具有增加渗透压和清除自由基的作用；灌洗前肺动脉内注射PGE；及增加 ECS渗透压和代谢底物、提高PH值使之略微偏碱均有助于抑制供体肺离体、低温、冷缺血保存期间OFR的产生。

ONOO〓 had direct vasoactive effect for relaxation of precontracted isolated pulmonary artery. Relaxing action of ONOO〓 was weak and was negtively regulated by endothelial cells, further supporting the notion that ONOO〓 may be involved in pulmonary hypertension in the early stage of ES.

用离体血管环检测张力方法，发现ONOO〓具有一定的舒张肺动脉作用，但舒张效应较弱，并受到血管内皮细胞的抑制性调节；抑制K〓通道和PARS活性可增强ONOO〓对离体兔肺动脉的舒张作用。

Using normal roots from aseptic seedlings and hairy trots originated from Agrobacterium rhizogenes A4-mediated genetic transformation of L.

目的：探索光照和植物生长物质对宁夏枸杞无菌苗正常根和发状根离体生长的影响，建立离体根的最佳培养体系。

ResultsThe autorhythmicity of the isolated right atriums were inhibited after treated with DSS. Moreover, their contraction scale,contraction velocity and relaxation speed were significantly reduced in a dose-dependent manner.

结果3'大豆苷元磺酸钠可降低豚鼠离体右心房的自律性，明显降低豚鼠离体右心房的收缩幅度、收缩速度、舒张速度，且具有明显的剂量依赖性。

It was found that haemocytes were more sensitive to TBT in vitro than that in vivo.

活体处理组的降低幅度显著低于离体处理组，即血细胞在离体条件下要比在活体条件下对TBT敏感。

Results The pD2 value (the affinity to M-receptors of agonist) of Erycibele alkaloid's miosis is 3.60±0.15 and its IOP lowering action is 3.49±0.07. In the isolated iris contracting experiment, its pD2 value is 6.38±0.12. M3 receptor antagonist is the strongest antagonist in inhibiting the miosis, IOP lowering action and isolated iris pupillary contracting action of Erycibele alkaloid. 0.01% Erycibele alkaloid can cause the decrease of cAMP and the increase of cGMP in the aqueous humor.

结果 测定丁公藤碱缩瞳作用的pD2值为3.60±0.15，降眼压作用的pD2值为3.49±0.07，离体虹膜收缩作用的pD2值为6.38±0.12.M1～M3受体拮抗剂均可拮抗丁公藤碱的缩瞳作用、降眼压作用及离体虹膜收缩作用，其中以M3受体拮抗剂的拮抗作用最强。0.01％丁公藤碱可使房水环磷酸腺苷(cyclic adenosine monophosphate，cAMP)含量降低，环磷酸鸟苷(cyclic guanosine 3，5-monophosphate；cGMP)含量升高。
