四组

MaterialsThe study was conducted on healthy albino guinea pigs of either sex (initially weighing 200 ~ 300g, with normal Preyer s reflexes).

实验方法' 一、实验动物分组及耳毒模型的制备将豚鼠随机分成GM组、TMP+GM组、TMP组和正常对照组四组。

Methods］ Eighty white health male rabbits were divided into four groups (teletherapy group, local hyperthermia group, super lizer group and control group, 20 rabbits for each group).

方法］ 将健康雄性3年的新西兰大白兔80只，分成四组，外照射组、体外高频热疗组、超激光治疗组和对照组各20只。

To investigate the role of transmural dispersion of repolarization and cardiac restitution properties in arrhythimogeneity in LQT2, we observed the effects of d, 1-sotalol, hypokalemia and calcium channel blocker on TDR and cardiac restitution properties at different basic cycle length by using the arterially perfused rabbit left ventricular wedge preparation.

为探讨心室跨壁复极离散度和动作电位时程恢复性质的变化在LQT2室性心律失常发生中的作用，笔者采用冠状动脉灌注的兔左室肌楔形组织块制备LQT2模型。标本随机分四组：对照组；LQT2模型组（100 mol/L d，1-sotalol灌流）；模型+低钾(3 mmol/L)组和模型+低钾+维拉帕米(2 mol/L)组。

The allograft was harvested at 6h posttransplantation. Scrambled ODN group: The donor kidney was stored for 6h in ECs containing 1 u M Liposome/scrambled ODN complexes under hypothermal and hypoxia condition, then the donor kidney was transplanted into a SD recipient, and at 6h posttransplantation the allograft was harvested.

五、试验分四组：(1) Control组假手术组，Wister大鼠麻醉后，开腹后，即将伤口缝合，6h后切取左肾；(2) ECs组供肾经ECs(不含脂质体/ODN复合物)低温缺氧保存6h，移植到受体大鼠6h后切取移植肾；(3)deeoy onN组供肾经含1 pM的deeoy onN脂质体复合物的ECs 低温缺氧保存6h，移植到受体大鼠6h切取移植肾；(4)sc~。

Guinea pig sensitied by ovalbumin for model made and challenged with substance P were second group,and the last two groups were with steroid treatment and contral. Praxiology markers、 IgE、 histamine and SP were detected .Gene chip of rat were used in observing genes expression change.

再经卵蛋白致敏制作变应性鼻炎豚鼠模型，并按模型组，P物质干预组及类固醇激素治疗组及对照组分为四组，观察行为学指标，血IgE，组胺及SP含量的变化，通过鼠芯片观察基因表达谱及其变化。

Methods 72 mimic cervical radiculitis Wistar rats were divided into 4 groups randomly:moderate dose group of JZ-I,high dose group of JZ-I,Jingfukang group and control group.JZ-I of moderate dose,JZ-I of high dose,Jingfukang and water were given to the rats seperately.PGE2 was determinated by radioimmunoassay at 3,7,14 days after animal models had been made.

将72只模拟颈神经根炎Wistar大鼠随机分为四组：颈椎Ⅰ号中剂量组、颈椎Ⅰ号高剂量组、颈复康组及空白对照组，分别给予颈椎Ⅰ号中剂量、高剂量、颈复康及凉开水，于造模后3天、7天、14天，取血浆进行PGE2含量的放射免疫测定。

The first column is made up of units referring to overvaluing of the blood relations（Oedipus marries his mother, Jocasta, for example）; column two expresses the undervaluing of such relations（Oedipus kills his father, Laius）; column three referring to the salying of the monster; and the forth column comprises names referring to some general order of human disability（'Oedipus'translates as 'swollen foot'）or, more specially, to 'difficulties in walking straight or standing up-right'.

第一组由高估血缘关系的神话素单元组成，比如：伊狄普斯娶了母亲卓卡斯塔；第二组由低估血缘关系的神话素单元组成，比如：伊狄普斯杀了父亲莱厄斯；第三组由征服怪兽的神话素单元组成，比如：伊狄普斯杀了怪兽斯菲克斯；第四组由一些代表人类普遍存在弱点或残废的名字组成，比如：&伊狄普斯&意思为&肿胀的脚&，也即表示此人不能向前直行或直立行走。

There were 2 cases of aspiration pneumonia in control group, 1 in group A, 1 in group B and 0 in group C.

完全随机法[1] 分为四组，每组 4例病人，干预 1个月，每组鼻饲 4 80次，4组病

6 Days after plate culture, the cell number and cell viability of PLGA microspheres was much better than that of PELA microspheres and free bFGF.

4培养1天后，四组细胞计数、活力均无明显差异，4、6天PLGA组细胞计数和活力优于PELA组和游离bFGF组。

Methods: 36 male SD rats were randomly divided into four groups: normal group, control group, tetracycline group and massage group.

将36只雄性SD大鼠随机平均地分为四组：正常组、对照组、四环素组、手法组。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
