After treatment with the above hormones, the rats were established anesthesia with urethan (1g/kg, i. p.); polyethylene catheters were inserted into the external jugular vein and the common carotid artery for drug administration, and then blood pressure was recorded. The arterial catheter was connected to a pressure transducer, and the blood pressure was displayed on the channel of BL-310 Experimental System of Biological Function through IBM computer. We assessed the changes of resting arterial blood pressure, the pressor responses of angiotensin Ⅱ(Ang Ⅱ, 0.01mg/kg), noradrenaline (NA, 0.01mg/kg) and adrenaline (Adr, 0.016mg/kg). The depressor responses of Ach (0.006mg/kg) and carotid sinus baroreflex were also discussed after treatment with the hormones in OVX rats.

用不同雌激素处理21天后,将动物用25%的氨基甲酸乙酯腹腔麻醉(1g/kg),做颈总动脉插管,通过压力换能器,将血压变化输入计算机,通过BL-310智能型生物信号显示与处理系统的压力测定模块,观察去势鼠及不同雌激素替代治疗大鼠静脉注射血管紧张素Ⅱ(AngⅡ,0.01mg/kg)、去甲肾上腺素(NA,0.01mg/kg)、肾上腺素(Adr,0.016mg/kg)的升压反应以及乙酰胆碱(Ach,0.006mg/kg)的降压反应和压力感受性反射的变化。

Other factors significantly associated with severe reactions after a field sting were vespid venom allergy, older age, male sex, angiotensin-converting enzyme inhibitor medication, and 1 or more preceding field stings with a less severe systemic reaction.

与野外蛰伤后发生全身反应相关、有统计学意义的其它因素有:胡蜂蜂毒过敏、老年人、男性、应用血管紧张素转化酶抑制药及先前曾有过不少于1次野外蛰伤后发生轻度全身反应史。

In the same time, water-soluble bidental phosphines ligand BISBIS sulfonated 2,2''-bis(diphenylphosphinomethyl-1,1''-biphenyl was synthesized, and water-soluble rhodium complex Cl was synthesized in situ. This complex which was used as catalysts to catalyze the hydrogenation of avermectin was also tested. Although the rhodium complex containing bidentate phosphine BISBIS showed a higher catalytic activity than one containing TPPDS, the selectivity for ivermectin was lower. How to improve the selectivity will be needed to studied in futur.

同时我们用磺化的2,2''-二-- 1,1''--联苯,以及它们的水溶性威尔金森型铑配合物和环辛二烯的阳离子铑配合物,在利用这些配合物作催化剂,考察它们在各种反应条件下对阿维菌素的选择加氢,由于反应条件以及复合催化剂体系的组成还需要进一步优化,虽然双齿膦配合物显示了较高的活性,然而选择性还有待进一步提高。

Objective To explore the clinical significance between plasma levels of high-sensitive C reactive protein and atherosclerosis in patients with essential hypertension.Methods By measuring hs-CRP,endothelin,homocysteine,lipid and caroid artery echocardiography,ninety patients were divided into three groups equally,among them,the first group suffered 1-2 degree essential hypertension;the second group suffered 3 degree essential hypertension;excluding hypertension,coronary heart disease,diabetes,infections disease and tumour,control group as a third group was analyzed.

目的 对不同程度的原发性高血压患者进行血浆高敏C-反应蛋白(C-reactive protein,CRP)检测,探讨超敏C-反应蛋白在动脉粥样硬化疾病中的临床意义方法对30例1~2级原发性高血压患者(第1组)和30例3级原发性高血压患者(第2组)进行hs-CRP、内皮素、同型半胱氨酸和血脂检测、颈动脉超声检查,与除外原发性高血压、冠心病、糖尿病以及各感染、肿瘤患者进行比较分析。

Solubility of silicon dioxide is earlier soluble than delignification in AP for rice straw.

在蒸煮温度70℃时,脱硅反应速率常数是脱木素反应速率常数的3.78倍。

The reason may be that complex formed by rhodium and halide was difficult to produce the catalytic active species. Therefore halide ion was the poison for the rhodium catalyst in hydroformylation of olefins in ionic liquid. The effect of double long chain cationic surfactant (DCMAB, dicetyl dimethylammonium bromide) on selective hydrogenation of cinnmaldehyde catalyzed with RuCl3·x H2O/TPPTS was studied.

进一步的研究表明在使用有良好反应活性的两种催化剂HRh3 、Rh_2进行催化反应时,向体系中加入含有卤离子的化合物时将使反应活性大大降低,而且随着卤化物加入量的增加,催化剂的活性迅速下降,这是卤离子可能和金属铑作用使它难于生成催化活性物种,进一步证明卤素离子是引起催化剂活性下降的极其重要的因素。
