采用高速摄像技术对硅系延期药的动态燃烧过程进行了研究，计算了延期药燃烧的瞬时速度和平均速度。

Dan Rong medicine and the process that add drug is trival, complex, and relapse puncture infusion bottle stopper is easy interfuse dirt, impurity, easy cause particle to fall off cause pollution.

但溶药和加药过程繁琐、复杂，且反复穿刺输液瓶塞轻易混入灰尘、杂质，易引起微粒脱落造成污染。

Results of performance test show that the double-modular charge made up of module A and module B is preferable to the propellant charge of bag form in performances, and meet the needs of GC45-155mm gun for capable of interior ballistics.

性能考核试验表明，由A、B模块组成的双模块系统，各项性能优于传统的布袋式药包装药，可以满足GC45-155火炮的内弹道要求。

The dose-response curve of histamine was shifted parallely to the right. pA2 was 9.34±0.61. The guinea-pigs were effectively reduced the rate of histamine induced death, decreased reaction extent of shock (P＜0.01) and prolonged latency period of shock (P＜0.05) by orally administered cetirizine ranged from 0.1, 0.2 and 0.4 mg.kg-1. The capillary permeability to intracutaneous injection of histamine was potently inhibited by orally administered cetirizine ranged from 0.0625 to 0.25 mg.kg-1 in mice, blue area obviously decreased (P＜0.01), and dose-response curve existed obviously. In which the effect of these dosage groups were superior to the group of chlorphenamine.

结果：西替利嗪3×10-8～3×10-7mol.L-1可剂量依赖性地对抗组胺引起的肠肌收缩，使组胺的量效曲线平行右移，pA2为9.34 ± s 0.61，西替利嗪0.1，0.2及0.4 mg.kg-1口服给药时，能明显减轻豚鼠静脉注射组胺所致休克反应的严重程度(P＜0.01)，并可延长豚鼠惊厥反应的潜伏期及降低死亡率(P＜0.05)，西替利嗪0.0625～0.25 mg.kg-1口服给药可显著对抗组胺引起的小鼠皮肤血管通透性的增高，使蓝染面积显著缩小(P＜0.01)，且存在明显的量效关系，3个剂量组的作用均优于氯苯那敏组。

The intranasal route of drug administration is feasible and promising.

鼻内给药是一种可行的有前途的给药途径。

Objective: To study the pharmacokinetic of 10-Hydroxycamptothecin HCPT by intraperitoneal administration.

中文摘要：目的：研究羟基喜树碱腹腔内给药的药代动力学特点。

To date, the mechanism of resistance to antibiotics, particularly β-Lactam class of antibiotic, is becoming exceedingly complex.

尤其对临床上使用较多的头孢菌素类、青霉素类等β-内酰胺类抗生素的耐药，已给人类健康造成巨大威胁，急需阐明其复杂的耐药机制。

ESBLs was the main reason of Gram-negative bacteria drug- resistant toβ-lactam antibiotic.

产ESBLs的菌株耐药题目已经成为当前全球最重要的医院内耐药题目之一。

One week after administration of lead acetate and cadmium chloride, the numbers of NOS-positive IC reduced significantly.

给予醋酸铅和氯化镉1周后，NOS阳性的睾丸间质细胞数量明显减少，并随给药时间延长而加重，NOS活性逐渐降低，给药4周后NOS阳性的睾丸间质细胞几乎不着色。

The results showed that when the proportion of the resistant subpopulation within the h-VRSA was low, te level of the toxic factor and its pathogenicity to animals had no difference from that of the standard strain. If proportion of the resistant subpopulation increased the level of coagulase and lecithinase changing from positive from negative and the ring of hemolysis disappeared. The speed of proliferation of the organisms in the animal slowed down and the LD50 increased.

结果 当试验菌株中耐药亚群的比例较少时，其毒力因子及动物致病性检测结果与金葡菌标准菌株无显著差异；随着试验菌株中耐药亚群的比例增加，表现为血浆凝固酶、卵磷脂酶由阳性转为阴性，血琼脂平板上溶血环消失，细菌在动物体内增殖速度减慢，对动物的半数致死量(LD50)增加。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
