北五味子对犬条件反射的影响

国外文献关于北五味子对条件反射的影响说法不一。本工作就此问题作某些探讨。以拍节音作为条件刺激结合食物强化对犬形成阳性条件反射,而后使其消退,并观察不同剂量的北五味子对消退抑制的影响。实验证明,在条件反射消退初期,对犬使用小剂量(0.03克/公斤)的北五味子能减弱消退抑制;0.05克/公斤时效果不定;0.1—0.2克/公斤时能加强消退抑制.但当消退抑制已巩固形成后,则北五味子不论剂量大小皆不表现任何影响。小剂量北五味子对消退抑制的影响在表现上与咖啡碱相似,但较后者为弱,因为后者当消退抑制巩固形成后仍能使消退抑制减弱。     

Effect of auricular acupuncture on oxygen consumption of boxing athletes

Boxing is an official sport at the 2008 Beijing Olympic Games and the fast development of world-class high strength training and sport science has made a significant impact on scientific training. Boxing needs high cardio-respiratory function, speed, muscle strength, and anaerobic and intensive physical demands including weight control covering the grading of athlete's.     

Hydrophilic Polymers with Potassium Salt and Microporous Polysaccharides for Use as Hemostatic Agents

BACKGROUND Postoperative bleeding can lead to complications such as hematoma, infection, dehiscence, and an unscheduled office visit. Topical hemostatic agents can be used to aid in hemostasis.
OBJECTIVE The objective is to familiarize physicians with topical hemostatic agents—hydrophilic polymers with potassium salts (Urgent QR powder) and microporous polysaccharide hemispheres (Bleed-X).
METHODS Two hemostatic agents, microporous polysaccharide hemospheres and hydrophilic polymers with potassium salt, are discussed. The literature is reviewed.
RESULTS Numerous types of hemostatic agents exist. Topical hemostatic agents are safe, cost-effective, and efficient.
CONCLUSION Microporous polysaccharide hemospheres and hydrophilic polymers with potassium salts can be an adjunct to hemostasis after cautery and ligation. Patients can apply hemostatic agents if they experience any bleeding leading to decreased office visits. Hemostatic agents used intraoperatively shorten bleeding time and enable the physician to use less cautery. Using hemostatic agents can lead to fewer hematomas, infections, and office visits.

我们自1958年11月起至1962年8月止,在寻找抗肿瘤药物的研究中,曾经对311种植物袖、中药单方及47种中药复方的制剂及成分在动物移植性肿瘤进行了筛选.本文即此项研究工作的总结报告.     

黄花开口箭(Tupistra aurantiaca Wall.)的强心作用

用黄花开口箭根茎制成酊剂,将所含乙醇在水浴锅上蒸发后,其残渣对Legals及Keller-Kiliani应呈阳性,证明为强心甙类.酊剂蒸发乙醇后用蒸馏水溶解,过滤后所得的水溶液,通过在位蛙心及兔心、猫心电图及离体豚鼠心实验,证明有强心作用,其强心作用特点类似洋地黄.按中国药典鸽法测定其效价,折合生药为207.14±13.07毫克/公斤(标准差).     

Systemic candidiasis in premature infants

Abstract Four cases of systemic candidiasis in premature infants with different clinical presentations are reported. Diagnosis of the condition can be difficult as clinical manifestations are non-specific and Candida may not be recovered in blood culture. The condition should be suspected in predisposed babies with unabating or deteriorating infections despite appropriate antibiotic therapy. We propose routine microscopic urinary examination for Candida as a screening test for the infection.
