耐受性

Several studies have identified genes that play important roles in stress tolerance and virulence. For example, genes involved in osmotic stress tolerance, acid and alkaline tolerance, oxidative stress tolerance, extreme temperature tolerance, and bile salt tolerance have all been implicated in the virulence of L.

在压力存在的情况下能启动一些基因的表达，以增强细菌对环境的耐受性，这些基因包括与耐受渗透压、酸碱性环境、氧化、极端温度和宿主体内胆碱等环境压力相关的基因。

The results showed that LB1, LB2 have some resistant capacity of acid and bile, and can produce acid during progenition. Furthermore they could inhibit the growth of colon bacillus, salmonella, grape cocci and streptococcus in different degree.

结果表明，菌株LB1、LB2、SB1对酸有一定的耐受性；对胆汁能够耐受且适应生长；在其繁殖生长过程中能够产酸；对大肠杆菌、沙门氏菌、金黄葡萄球菌等均有不同程度的抑制作用。

Hypoxia induces the resistance of tumor cells[4];and the heterogeny of solid tumors result in the appearance of subpopulations of differentproliferative potency in the same tumor tissue, so that the target cells sensitive to cell cyclespecific drug are reduced.

目前有研究认为：实体瘤部分细胞缺氧和肿瘤组织的异质性可能是导致肿瘤对放疗和化疗产生耐受的主要原因之一，缺氧可以诱导肿瘤细胞对放疗和化疗的耐受性[4]，实体肿瘤的异质性可使同一瘤组织内具有不同增殖潜能的癌细胞亚群存在，导致细胞周期特异性化疗药物作用的靶细胞减少。

However, the size and number of colonies are less than which in anaerobic TYL medium. It can not grow in aerobic TYL and TYG media. Bifidobacterium longum can tolerate radiation dose as high as 80 Gy, which is the total dose in clinical radiotherapy. Therefore, Bifidobacterium longum has the potential to be the vector for cancer gene therapy combining radiotherapy. Besides, this is the first study to investigate the tolerance of X-ray radiation for Bifidobacterium longum.

此外，从本研究中得知Bifidobacterium longum可耐受高达80 Gy的辐射剂量（单次照射，存活分率为22 ％；以分次照射每次给予2 Gy来估算，存活分率为67％），此剂量为临床放射治疗一般给予的总剂量，因此证实Bifidobacterium longum有很大的潜力做为癌症基因治疗合并放射治疗的载具，本研究也是首篇调查Bifidobacterium longum对放射线耐受性的研究。

Subjects had more serious symptoms, more quickly onset of vection and more short rotation time when they were lying.

不同强度视觉与前庭系统感觉冲突影响视运动错觉的发生时间和旋转耐受性，表现为冲突越强，视运动错觉发生的时间越早，旋转耐受时间越短；视觉与前庭神经系统感觉冲突的增加可加重晕动发生时的症状。

Saccharobiose was used to maintain the osmotic concentration of the solution, The effect of osmotic pressure on livability, body volume and activity of the tadpoles were analyzed with ANOVA.

为了解中华蟾蜍蝌蚪对高渗溶液的耐受性，采用常规静态实验，用蔗糖调节溶液渗透压对蟾蜍蝌蚪进行渗透耐受实验；采用方差分析统计溶液渗透压对蟾蜍蝌蚪的存活率、体积变化和活动性的影响。

There was no recurrent after one year follow-up. Conclusion: The thoracoscope for spontaneous pneumothorax has the advantages of less ache,safety,reliable therapeutic effect ,effective and low price ,and it is the better choice especially for the patients who have bad pulmonary function and can not tolerate surgery.

自发性气胸采用内科电子胸腔镜治疗，具有安全性佳、疗效好、费用低、患者耐受性好的特点，尤其适合肺功能差不能耐受胸外科手术的患者。

In addition, infants who received continuous transpyloric feeding were compared to those who received intermittent nasogastric feeding for their severity of apnoea and bradycardia, feed tolerance, nutritional intake and weight gain.

TP组：比较TP前、后呼吸暂停及心率减慢的发生情况，喂养耐受性营养摄入及体重增长速度，并与相对应胎龄的NG组的患儿比较呼吸暂停，心率减慢，喂养耐受性及体重增长速度。
