Cases with renal transplantation were performed with dynamic state CDFIin Ultrasound Dept. of Nan fang Hospital from April, 2005 to October, 2006. Theexamine time is respectively after operation in three days, seven days, one month andthree months. Before operation examine the condition of uropoiesis function such as apair of kidney, ureter, bladder and cardiac function. After operation reexamine thecondition of cardiac function once again, and examine TK detailed and completely:First, using two-dimensional imaging to observe the shape and the volume of the TK.Secondly, using Color Doppler to observe the renal artery and each artery inside theTK. Finally, using pulsed Doppler to measure the peak systolic velocity, enddiastolic velocity and resistance index.

Methods: Integrated and disrepaired skins in the rats were smeared with Salicylic AcidPhenol Liniment by the maximum tolerated dose only. The toxic reaction of the animals were observed and recorded continuously from the beginning of using the drug to 7 days, and evaluated by using the general standard of the reaction of skin stimulation in pharmacology. Animals were executed by taking off acanthi and blood was collected to check up the periphery blood routine and serum biochemistry at the end of the observation of the rats. And after the dissection, the pathological change of main visceras, such as heart, brain, liver and kidney were observed with naked eye and pathological slices. The data of this experiment was used to calculate the value of LD50 by using Bliss rule.

via their study the authors considered that it is lacking in logical reasoning for the authors of the paper titled on the return of competitive sports to their game playing nature - thoughts inspired by stimulant prohibition to further draw such a conclusion as the nature of competitive sports being game playing from their analysis of the hazards of using stimulants.the authors of this paper pointed out the followings: there is no intrinsic certain relation between these two issues; we should neither discuss the hazards of using stimulants to physical and mental health and the harm of competitive sports to the body, psychology and morality of the athletes at the same level, nor consider that the hazards brought by using stimulants to the healthy development of sports are as equally bad as the phenomenon of unfairness existing in the development of competitive sports and the phenomenon of science and technology "dissimilating" competitive sports; the fundamental goal of prohibiting the use of stimulants is to maintain the spirit of fair competition of competitive sports.

兴奋剂事件有隐情？摘要：研究认为《论竞技体育的游戏本原回归——由禁用兴奋剂引发的思考》由分析使用兴奋剂的危害入手，进而提出&竞技体育的本原是游戏&这一论断缺乏逻辑推理。研究指出，两者之间没有什么内在的必然联系；不能将使用兴奋剂对身心健康的危害与竞技体育对运动员身体、心理、道德等方面的伤害放在同一层面讨论，也不能将使用兴奋剂给体育健康发展带来的危害与竞技体育发展中存在的不公平现象、科技使竞技体育的&异化&现象相提并论；禁止使用兴奋剂的根本目的是维护竞技体育的公平竞争精神。
