Methods A randomized controlled trail was carried out in 41 patients. The medication design was based on the findings that the half life time of salvianolate was less than 2 h and its time of clearance uas 12 h. The treatment group (n=20) was treated with salvianolate at the dose of 200 mg, intravenous drip, twice a day, and the control group (n=21) with salvianolate at the dose of 200 mg, intravenous drip, once a day. The curative effects of salvianolate on angina pectoris (with syndrome of heart-blood obstruction) in the two groups was compared.

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 number of chickens in each group is 16 for SPF chicken At 4 weeks of age, chickens were eye-drop immunized with the recommended dose of commercial IBV vaccine, or vaccinated intradermally via wing with 5×106 PFU rFPV-IBVS1 or 5×106 PFU S-FPV-017. Four weeks after vaccination, chickens in all groups were challenged by bronchitis injection with a lethal dose (0.2ml 8.5EID50/0.1ml) of IBV XJ3 strain After challenge, chickens immunized with rFPV-IBVS1 and commercial IBV vaccine were all protected from death; the result indicated that rFPV-IBVS1 can protect chickens from the infection of IBV.

攻毒后的结果显示所有含rFPV-IBVS1免疫组的SPF鸡均100%保护而免于死亡；IBV弱毒疫苗免疫的SPF鸡也获100%保护，免疫以后的抗体跟踪检测证明rFPV-IBVS1诱导的抗IBV抗体水平低于IBV弱毒疫苗免疫组；攻毒后进行的IBV分离和PCR检测结果表明IBV弱毒疫苗免疫的SPF鸡能够更好地阻止攻击强毒的感染。
