我们现在的生理学知识其中的一些源于对于其他动物的研究诸如：青蛙，兔子，猫和狗。很明显一个特殊的生理过程在大范围不同生物种都有一个共同的基本原理。假设相同的原理适用于人类是合理的。知识从这个方法中得到。它给了我们一个巨大的洞察力去研究人类生理学并赋予我们坚固的基础为了很多疾病有效治疗。

反向回流循环这样一种控制系统，它可以在后续的机体紊乱中保持变化性在一定的程度，根据上述病症举例中的血糖，一些基础的原则可以被应用在其他生理变化如体温、血压，血浆渗透压。反向回流循环需要对发生变化的感应，但不是对其他生理变化的感应器，所以渗透压感受器可以对体液渗透压给与反馈，但其他如体温和血压的变化却不行。从感应器反馈的信息必须是和一定程度的比较综合表进行对照。如果两项不匹配，错误信号会发送给驱动因子，该驱动因子可以重载变化率至指定的水平，这些反向回流可以被一些简单的发热系统所验证，驱动因子作为热源，当房间温度低于设定值，温差会被温度计截获并发送至热源，热源会一直工作直到达到预定温度。

The purpose of Natural Medicinal Chemistry
From natural medicines in the research and development of new drugs (including the lead compound of structure modification and transformation, the total synthesis), which our study of natural medicines are the main purpose of the chemical. Pure compounds to develop new drugs is very difficult, long cycle and the high cost of chemotherapy side effects, and easy to produce drug resistance, cause injury to human health, and from green plant life of the natural active ingredients often have high security, so to natural medicine as raw materials of drugs and drug extracts in the world is increasingly popular
(1) a wide range of natural products, novel structure, pharmacological screening of the hit rate than the high synthetic compounds derived from natural lead compounds promising treatment for difficult cases of new drugs, so drugs from the natural development of new drugs has become a Top research directions. It was predicted that the future of natural drugs and chemical substances will be evenly divided, and biology were the three drugs with a tendency
(2) A number of natural active compounds, because there are some defects, such as efficacy is not satisfactory, or side effects must exist, or because the content is too low, shortage of resources, it is difficult to Medium derived from natural raw materials, or because the structure was too complex, synthetic is also very difficult, so there is no direct the development and utilization of their own future. However, the natural active ingredients for the lead compounds, structural modification or structural alteration, and eventually developed into new drugs.
For example: synthetic morphine substitutes - is scheduled for piperaquine (meperidine), morphine is retained in the structural parts of an effective (analgesic effect of the same!), And its addictive than morphine decreased. Another example: the active ingredient in coca leaves cocaine has a very strong narcotic effect, but toxic, easy to addiction, through research design and synthesis of local anesthetics such as procaine. Again Example: to extract from the Artemisia annua with the separation of anti-malarial activity of artemisinin, is a heat-labile compounds, such as its hydrogenated, methylated derivatives artemether made after the markedly improved stability, anti - more enhanced malaria activity.

问题补充的翻译：
In the 21st century, "return to nature" of the world trend, the traditional medicine once again full of great vitality and show broad prospects for development. Western medicine sector has changed the original opinion, interested in Chinese medicine to Chinese medicine in Japan, Germany, the United States and other Western developed countries has been given scant attention up.

World Association of Traditional Chinese Medicine in 1994, set up in Los Angeles, the West has also opened a number of institutions of higher learning professional courses on Chinese medicine or the establishment of a Chinese medicine research center. The United States Food and Drug Administration (FDA) have begun to formally accept the traditional Chinese medicine compound products. This trend of Chinese medicine into the world to provide an unprecedented good opportunity. Modernization of Traditional Chinese Medicine is the inevitable trend of the modernization of Chinese medicine must be to the world and the benefit of mankind. The development of Chinese medicine is the medicine our country in the competition to win one of the effective ways.

Natural pharmaceutical chemistry purpose

From developing the new drug developing in natural medicine (the structure including the guide compound polishes with make over , entire combining),this is that we study natural pharmaceutical chemistry major objective. The degree of difficulty the pure compound new drug is developed is big , the period is long , cost is high, the poisonous chemistry medicine side effect is big , easy to produce resistance to drugs, health brings about to the human body hurt, but the activity component sometimes has higher security from nature that green gets in life plant , medicine and medicine taking natural medicine as raw material extract thing favour accepting people gradually in all the countries in the world therefore.
(1) is made by nature a great variety , structure are new and original , the hit rate that the
pharmacology sifts is higher than composing compound , originate from natural guide compound having
hope very much becoming the new drug curing difficult and complicated cases's , study direction
therefore one already becoming a nowadays from the new drug developing in natural medicine is
popular. Somebody forecasts , future natural medicine will have equal shares with chemistry
medicine, power of assuming a situation of tripartite confrontation together with living things
medicine. (2) is not the natural activity compound short, because of existence some defects,
existence definitely poisons or a side effect, or resource shortage, is difficult to draw materials
from natural raw material middle because contents are very low,or excessively, complicated ,
compose because of structure if pesticide effect is not ideal, also very difficult , develop the
future making use of therefore self is not direct. And but take natural activity component as guide
compound, the structure being in progress polishes or structure reforms, ultimate exploitation
becomes a new drug.
For example: The cries of a baby replaces the morphine combining substitution- stablely (dolantin)
, (the effect is invariable now that effective in having reserved morphine structure part eases
pain)! ,Use whose more obvious than morphine habituation sex lessening. Such as: In Gukeye, active
constituent cocain has the very strong anaesthesia effect, but big , easily able addiction of
toxicity, by studying the ethocaine designing the anaesthetic having composed waits. No matter how
regular: Active Artemisia apiacea is plain from the malaria extracting having parting for in
Artemisia apiacea resisting , is one kind of hot unsteady compound, the stability improves
obviously after manufacturing the Wormwood A ether derivative if hydrogenate with the person ,
methylate,resist malaria activity strengthening especially.
