All isolates are sensitive to Cephalosporins antibiotics and Aminoglycosides antibiotics such as Amikacin, Cefazolin, Cefradine, Cefoperazone, and Ceftriaxone. Thirty-eight isolates are extremely resistant to Penicillins antibiotics, Lincomycins antibiotics, Tetracyclines antibiotics and Macrolides antibiotics such as Midecamycine, Lincomycin, Carbenicillin, Tetracycline, Amoxicillin and so on. Antibiotics sensitivity test provides guidance for antibiotic application and scientific foundation from poultry farms.

The research indicated that under the compound use of hydroquinone and methyl quinone or independent use of phenothiazines or nitrogen oxygen free radical made the polymerization retarder, opposite-methyl-phenylsulfon made the esterification catalyst, toluol made the backflow including water condition, the acid mellowly compared to when it was 1.15, the production rate of the synthesis methylacrylic acid polyethylene glycol single methyl ether (400) ester may achieve 98.9%, was extremely similar to the overseas product functional group structure.

Intravoneous injection of 0.5mg/kgBW jingsongling cause the 60 minutesrelaxation of goat gastric motor.The effects of jingsongling on the gastric motor ofgoat is major of effects of α2 -adrenoceptor agonist,as well as that of α1 -adrenoceptor agonist,the effects of α1 -adrenoceptor agonist concentrate at thecardic and pylorus;the function of α2 -adrenoceptor exit widely at cardic,pylorus,rumen,reticulum,omasum and abomasum,the function at different part is not the same.The lowestdose of jingsonglinginhibiting the amplitude and frequency of the gastricmyoelectric is 0.01mg/kgBW;the influence of jingsonglingto the gastricmotility of goat is dose-dependent,and the amplitude regain after the frequency ofgastric myoelectriv wave.When the goat revived,the gastric motor function is notreach the level of the normal;the major reason ofjingsongling cause the goat gastricrelaxation is the amplitude renew slowly.The intravoneous injection ofjingsonglingfirst,after 5 minutes,intravoneous injection the antagonist,the effect of prazosin and idazoxan mixed is best,which can fast reversal of theinhibition of jingsongling on the gastric motor of goat,the effects of idazoxan isgood,and the prazosin block the effection of jingsongling is better than that ofxylazine,especially at cardia and pylorus.When intravoneous injection of0.5mg/kgBW idazoxan and/or prazosin only,the amplitude of gastric myoelectric ingoat increases at a certain degree,but the frequency is not changed.

静脉注射0.5mk/kgBW的静松灵引起山羊胃蠕动弛缓长达60分钟;静脉注射0.5mg/kgBW的静松灵对山羊胃蠕动机能的影响是以α2肾上腺素受体作用为主的,兼有α1肾上腺素受体的作用,而且静松灵的α1肾上腺素受体的作用主要集中在幽门和贲门;α2肾上腺素受体的作用广泛存在于贲门、瘤胃、网胃、瓣胃、皱胃和幽门中,不同部位间有功能上的差异;静注0.01mg/kgBW的静松灵是对山羊的贲门、瘤胃、网胃、瓣胃、皱胃和幽门的肌电波频率和振幅均产生影响的最低剂量;静注一定剂量的静松灵对山羊胃蠕动的抑制作用与剂量呈相关性;而且山羊胃肌电波振幅的恢复比肌电波频率的恢复慢;苏醒时山羊的胃蠕动机能尚未恢复到正常状态;静松灵引起山羊胃弛缓的主要原因是由于胃肌电波的振幅恢复慢;静注0.5mg/kgBW的静松灵,5分钟后静注0.5mg/kgBW的拮抗剂时,咪唑克生+哌唑嗪的作用最好,能迅速地逆转静松灵对山羊胃蠕动的抑制作用,咪唑克生也有很强的拮抗作用,而哌唑嗪对静松灵的拮抗效果好于对隆朋的拮抗;单独静注0.5mg/kgBW的咪唑克生和/或哌唑嗪时,山羊的瘤胃、网胃、瓣胃、皱胃、贲门和幽门的肌电波振幅有一定程度的增强,而肌电波频率未见变化。
