Abstract: Abstract： Objective To investigate and evaluate the effects of the two anesthetic methods，sodium pentobarbital plus isoflurane anesthesia and sodium pentobarbital intravenous anesthesia，in experiments of femur fracture in dogs．Methods Ten dogs were equally divided into A and B groups．After induction of anesthesia by sodium pentobarbital．group A was boosted with 0．8％isoflurane to maintain anesthesia status．Group B was given intravenous sodium pentobarbital anesthesia．During anesthesia，heart rate，blood pressure，oxygen saturation and body temperature were monitored at different time points．The data were analyzed using the SPSS 1 3．0．Results Before and after receiving inhalation anesthesia，group A showed significant difference(P<0．05)in heart rate (HR)，oxygen saturation(SP02)，and body temperature(TPR)after 5 min of treatment．Physiological indexes of the dogs were stable and recovery was fast．In the pentobarbital sodium treated group，only the body temperature (TPR)was significantly different(P<0．05)pre-and post—anesthesia．At 45—60min post anesthesia，the dogs resumed eyelid reflex and muscle tremors，so additional pentobarbital sodium was required．Conclusion The inhalation anesthesia is efficient，acts stably，and makes the recovery fast．

摘要： 摘要：目的根据最新颁布的国家标准，对黑龙江省的实验小鼠、大鼠的遗传学质量进行调查。方法参照国家标 准《实验动物近交系小鼠、大鼠生化标记检测方法》GB／T 14927．1—2008，应用乙酸纤维素板，对来自4个单位的 BALB／c和C57BL／6实验小鼠及3个单位的SD和Wistar实验大鼠进行生化标记位点的检测。结果被检的 BALB／c小鼠和大鼠中均存在杂合。结论大鼠符合封闭群遗传概貌，但近交系小鼠出现了遗传漂变。
