To evaluate the interaction effects of the three chemical components, Cochinchinenin A, Cochinchinenin B and Joureirin B, of dragon's blood resin, a new method of isobologram on the basis of the Loewe Additivity was established and could analyze the interaction effect of the three drugs with variable potency rations. By using this new method we assessed the interaction characteristic of the combined inhibition effects of three chemical components of dragon's blood resin on the evoked discharges of wide dynamic range neurons of spinal cord in rats.

It is true that human ontogeny need not be a recapitulation of the evolutionary events that led up to the formation of language capacity.

可以确定的是人类的个体发生不是导致语言能力的形成和进化的重点，我们没有实验数据推断语言能力与动物演进的关系。

The journal publishes papers on the interrelationship between the experimental and environmental sciences, the results of original research or new investigations into the changing situation in which subsistence agriculture, closely controlled by its physical and biological environments, improvement of farming, indigenous economics associated with rural sociology, and the practice of tropical agronomy and animal husbandry.

杂志主要刊载论文，内容涉及实验科学与环境科学的相互关系，原始研究的结果或对由物理和生物环境严格控制的少有余粮的农场经营方式的处境改变的新研究，畜牧改善，与田园社会学相关的本土经济，以及热带农学和动物管理的实践。

For the first time in the world, an in vitro testing model based on FRTL-5 cell line for thyroglobulin disruptors was established, as well as an in vivo testing model acting as a compensation for the in vitro method. The feasibility of the combination of in vitro and in vivo screening methods was discussed, as well as the mechanism of thyroid hormone disruptors.

为达到这一目的，我们在国内外率先建立了FRTL-5细胞对干扰甲状腺球蛋白的化学物的体外甄别方法模型，并建立相应的体内动物实验模型以弥补体外甄别方法在特异性上的不足，探讨以此建立体外、体内试验相结合的甄别方法体系的可行性，同时初步探讨甲状腺素干扰物的作用机制。

Since the infant CPB needn't high flow rate, the 12mm pitch wheel with higher anti-resistance ability is more suitable in this study;(3) The axial flow pump with 12mm pitch wheel was used in animal experiment.

考虑幼婴儿体外循环中对流量的要求不高，因此抗阻能力较高的螺距12mm的叶轮更适合本设计的要求；（3）在动物实验中选用12mm螺距的叶轮安装在轴流泵中。

The immuneological functions of watery extract, sixty-five and ninety-five percent of ethanol extracts of Caesalpinia Sappan L. in mice were studied. It was reviewed that extracts had effects on the production of hemolysin antibody by CRBC and meshy endothelium phagocytosis function in mice.

利用水、65%、95%乙醇提取物进行了免疫药效学的动物实验研究，考察了上述提取物对红细胞所致的小鼠溶血素抗体生成的影响以及小鼠网状内皮系统对血流中惰性碳粒的吞噬功能的影响。

Results of experimental animal showed: atherosclerosis and its calcification needed some condition. In calcific plaques, the change of calcific quantity could reflect the progression of atherosclerosis.

动物实验证实：动脉粥样硬化和在此基础上发生的钙化都需要一定的条件，已经钙化的斑块，其钙化参数值的变化能够反映动脉粥样硬化的病变进程。

The results of respiratory mechanics, homodynamic mechanics,aterial blood gaS, and inflaInInatory factors [TNF- Q, IL-l fl, IL-6,IL-l0, and adrenomedulin] which detected in animal serumand bronchial alveolar lavage fluid obtained from tiP lObe,heart lobe, and diaPhragIn lobe of right lung seParate1y in the mongreldogs were measured before and after lung injury (including receivinglung protective ventilation).

本实验证明了 loS肺内／肺外不同源性 ARDS动物模型的差异性，而且AnDS的肺部病变存在不均一性和多形性的特点，对有关ARDS进行性低氧血症的发生机制提出了肺动静脉可能存在类似于右一左分流的肺内分流现象，以及因肺内分流而导致严重通气／血流比例失调的解释。发现小潮气十PEEP通气对肺内源性 ARDS疗效不佳，而俯卧位＋小潮气－I－ PEEP通气对肺内／肺外不同源性ARDS均有较好的疗效。。

Objective To study the efficacy of Melilotus extract in rehabilitation of operation of anal rectal disease.Methods In experimental study,the animal models were established by laparotomy in rats.The blood in dressing and the granulation tissue in wound were observed in post-operation.Then,the influences of Melilotus exˉtract to the bleeding and healing in wound were compared with the difference between that of the therapeutic group and that of the controls.

目的 探讨研究草木犀流浸液在肛门直肠手术后康复中的作用方法首先进行动物实验，建立家兔开腹手术模型，观察家兔开腹术后对照组和治疗组伤口敷料渗血量的变化，以及观察伤口处新生肉芽组织的生长状况，从而评价草木犀流浸液对手术后切口渗血的影响和促进伤口愈合的作用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
