Concerns About The Safety Of Vaccines - Free Essay Example

Until just a couple of centuries ago, infectious scourges roused fear into the minds of all people. Just over a hundred years ago, the infant mortality rate was at a mind-boggling 20 percent. In a time before effective vaccines, diseases like smallpox, diphtheria, measles, whooping cough, and more were some of the most common childhood killers. Fortunately, in developed and industrialized nations today, vaccines are widely available and affordable. As a result, these diseases have been contained and even in some cases, eradicated, saving millions of lives and bringing peace to many minds. Surely, one could claim that vaccinations are one of the greatest achievements mankind has made. Unfortunately, many today refuse to vaccinate their children due to a variety of reasons. After understanding how vaccines work and the myths and facts that are associated with vaccines, one can see that not being vaccinated creates a public health threat and can have severe consequences for many. Due to this fact, children attending public school should be required by law to be up to date on all of their vaccines unless they are unable to for medical reasons. https://www.healthaffairs.org/doi/full/10.1377/hlthaff.24.3.611   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In 1796, the worlds first small pox vaccination was performed. After noticing that milkmaids who had been infected from cowpox were immune to outbreaks of small pox, Edward Jenner conducted a clinical trial. He discovered that when he took pus from a cowpox lesion and introduced it to an eight-year-old boy, he did not catch small pox when it was directly introduced to him six weeks later. This trial became the scientific basis for vaccinology and a century later the rabies vaccine was introduced and a century after that the polio vaccination trials began. These experiments were extremely effective and saving hundreds of lives, but how did they work? https://www.healthaffairs.org/doi/full/10.1377/hlthaff.24.3.611   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The human immune system is a complex network whose sole purpose is to fight off infectious microbes. Multiple specialized cells find, target, and destroy these microbes. Every cell has a unique marker, or antigen, on it and white blood cells called macrophages use these antigens to distinguish which cells are part of your body and which ones are harmful invaders that need to be destroyed. Macrophages digest most of these invasive cells, but carry the antigens back to the lymph nodes and display them on their surface so that other specialized cells called lymphocytes, can recognize them. There are two major kinds of lymphocytes, T cells and B cells. Offensive T cells kill human cells that have been infected by the microbe and defensive T cells secrete chemicals that help direct the other immune system cells. B cells make important antibodies. Antibodies work by attaching to the microbes antigen and then coating the microbe making it unable to function. Ant ibodies and antigens fit together like a puzzle. Each antibody can only fit with one antigen so the immune system keeps millions of antibodies on hand so that it is prepared against foreign invaders. About 50 million B cells are circulating in one teaspoon of human blood. Once attached to antigens, antibodies signal macrophages to come and destroy the microbe. Once T cells and antibodies eliminate the microbe faster than it can reproduce, the immune system is winning. The virus begins to disappear from the body. Once the disease is gone, B cells and T cells are converted into memory cell. Memory B cells can quickly make more antibody if needed. Memory T cells can divide and grow into a fighting army. If the body is re-exposed to the same infectious microbe, the immune system can quickly respond and stop the infection because it is able to quickly recognize the virus.   https://www.niaid.nih.gov/research/how-vaccines-work   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Vaccines are effective because they mimic natural infection. They contain a weakened form of the virus that does not reproduce very well. The human body is not able to determine that the vaccine viruses are in a weakened state and so they treat these viruses as if they are dangerous. The immune system responds and the vaccine virus is quickly eliminated. The mock infection disappears and humans are left with a supply of memory T and B cells that are ready at a moments notice should the true aggressive form of the virus enter the body at a future date. Although this process makes scientific sense, there are many parents who elect to not vaccinate their children for a variety of reasons. It is important to explore these reasons and decide whether or not parents of children have misconceptions about vaccinations, their side effects, their benefits, and so on. lhttps://www.niaid.nih.gov/research/how-vaccines-work   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   One of the most common reasons why parents choose to not vaccinate their children is for religious reasons. Unfortunately, the number of children not vaccinated for this reason is increasing and in communities where there is a higher percentage of those who are not vaccinated for religious reasons, there are more vaccine preventable outbreaks. When a parent refuses on religious ground, most claim that it is not because they are ignorant but rather that they have a very strong internal conviction that it is fundamentally wrong to vaccinate their children. Due to the fact that they have such a strong conviction, it is often difficult for medical practitioners to persuade these parents to vaccinate their children and help them change the views they have against vaccination. One of the scariest parts of religious exemption is the fact that these families often refuse all of their vaccines rather than just certain immunizations. Many worldwide religions have s tated positions regarding vaccines and whether or not they should be used. Looking at some of the mainstream religions worldwide presents some very interesting information. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4869767/   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   All mainstream religions besides the Dutch Reformed Church do not have any formal anti-vaccine doctrine as part of their religion. Catholics have expressed concern about the use of aborted fetal tissue that is used to manufacture some vaccines, however, this has not led to any formal restrictions for any vaccines. Muslims and Jews are prohibited from eating pork which is the basis for the gelatin in some vaccines. However, in Islamic tradition, those who receive these vaccinations based on the law of necessity, are not found guilty if there was no other alternative. Since vaccinations are injected and used for medical purpose rather than being eaten for the purpose of diet, vaccines are permitted. Similarly, Jews emphasize the community over the individual when it comes to disease prevention and so they support vaccinations in order to have disease prevention in their communities. https://www.ncbi.nlm.nih.gov/pubmed/23499565   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   This information is interesting because it seems to contradict the statistic that the majority of vaccine refusals are based on religious ground. The animal-derived gelatin as well as aborted human fetus tissue can pose a concern for the most orthodox and extreme members of the religions mentioned above. However, only a small percent of members belong to these sects or have extreme bishops, priests or rabbis that would vocalize against vaccines. Additionally, probably only a small percent of these children are even attending a public school. It seems as though religious exemption may just be an excuse used by many who refuse vaccines because they are uneducated or have heard negative things about vaccinations from someone else. 47 of the 50 United States allow vaccine exemption on the grounds of religious reasons. It would be very easy for many people to avoid vaccinations using the pretense that they are doing so under religion. https://vaccines.procon.o rg/view.resource.php?resourceID=003597   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Another common reason why parents refuse or delay vaccines for their children is personal or philosophical reasons. Fewer states allow philosophical exemption and some of these states require that parents meet with a health care professional to discuss the benefits of immunizations if they use this exemption. Although contrary to intuition, some parents feel that there are benefits to contracting these preventable diseases because it will build a stronger immune system. Others believe that receiving natural immunity by acquiring the disease is better than becoming immune through a vaccine. Some believe that the diseases that children are vaccinated for today are no longer prevalent enough for their child to be at risk of catching. They believe that there are more benefits that come from not receiving vaccines than for receiving them. Some think that if they are helping their children live healthy diets and active lifestyles, that they will be better able to avoid contracting these diseases even without getting vaccinated for them. Others do not see the diseases that are vaccinated for as dangerous and life-threatening and that if their child did contract one of these diseases that it would be easily curable. Many personal reasons stem from parents who are uneducated or ignorant about vaccines, how they work, and the diseases they prevent. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4869767/   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   All of the personal beliefs stated above are derived from misconceptions that parents have about vaccines. It is important that medical providers clear these misconceptions that parents have. If parents were aware of how vaccines work, they would know that there is no difference between immunity built by vaccines and immunity built by actually acquiring a disease because the immune system responds the same way in both cases. Education about the various vaccine-preventable diseases would inform parents that these are highly contagious diseases that are very life threatening which is why vaccines have been created for them. Some are not easily curable because they are viral so no antibiotics can be taken for them. Having a true understanding of herd immunity is also important for these parents who think they are safe because everyone else is being immunized.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Herd immunity is one of the most important reasons that everyone should be vaccinated. The idea of herd immunity is that when enough people are vaccinated in a community, the disease cannot travel as easily from person to person because those who are vaccinated cannot contract the disease and additionally, they are less likely to spread it. This means that it is very unlikely that those who are not vaccinated will not contract the disease. While herd immunity protects everyone, it is extremely important that a very high percentage of the community is immunized in order for herd immunity to work. Depending on how contagious a disease is, more of the population must be immunized in order for herd immunity to work. This percent can range anywhere from 85 to 95%. Many depend on herd immunity such as those who have a compromised immune system, those who are medically unable to receive vaccines, elderly people, newborn babies and young children that have not re ceived all of their vaccines yet and those who receive faulty vaccines. These individuals are all at a higher risk for contracting these vaccine preventable diseases and make up enough percent of the unvaccinated that it is so important that everyone else is vaccinated. Due to the fact that a slight drop in the number of vaccinated individuals in a population can cause a large drop in the effectiveness of herd immunity, it is not a reliable way of protecting children because it is indirect.   This idea can be seen in the graphic below: https://www.ovg.ox.ac.uk/news/herd-immunity-how-does-it-work https://fred.publichealth.pitt.edu/proj/measles/results.php   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Maybe the most frequent reason for refusing vaccinations are concerns about the safety of vaccines. Most of these fears rise from the media or things they have heard from others. Every person, educated or not, has their own opinion about vaccines and this can directly influence other peoples opinions. Some parents are concerned about vaccines causing autism. Others worry that bombarding children with so many vaccines at a young age can overwhelm their immune systems and these parents will often delay their childs immunizations. Some worry about side effects of vaccines and fear they are greater than what they have been told by their physicians. Fear is a great influencer and this is why it is important that there is trust between practitioners and parents. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4869767/

End of Chapter Solutions Corporate Finance 8th edition Ross, Westerfield, and Jaffe Updated 11-21-2006 CHAPTER 1 INTRODUCTION TO CORPORATE FINANCE Answers to Concept Questions 1. In the corporate form of ownership, the shareholders are the owners of the firm. The shareholders elect the directors of the corporation, who in turn appoint the firm’s management. This separation of ownership from control in the corporate form of organization is what causes agency problems to exist. Management may act in its own or someone else’s best interests, rather than those of the shareholders. If such events occur, they may contradict the goal of maximizing the share price of the equity of the firm. Such organizations frequently pursue social or†¦show more content†¦How much is too much? Who is worth more, Jack Welch or Tiger Woods? The simplest answer is that there is a market for executives just as there is for all types of labor. Executive compensation is the price that clears the market. The same is true for athletes and performers. Having said that, one aspect of executive compensation deserves comment. A primary rea son executive compensation has grown so dramatically is that companies have increasingly moved to stock-based compensation. Such movement is obviously consistent with the attempt to better align stockholder and management interests. In recent years, stock prices have soared, so management has cleaned up. It is sometimes argued that much of this reward is simply due to rising stock prices in general, not managerial performance. Perhaps in the future, executive compensation will be designed to reward only differential performance, i.e., stock price increases in excess of general market increases. 8. 9. 10. Maximizing the current share price is the same as maximizing the future share price at any future period. The value of a share of stock depends on all of the future cash flows of company. Another way to look at this is that, barring large cash payments to shareholders, the expected price of the stock must be higher in the future thanShow MoreRelatedCorporate Finance Notes1881 Words   |  8 PagesStudy notes By Zhipeng Yan Corporate Finance Stephen A.

Drug Legalization by Seth Sprague Essay - 2448 Words

Page 1. I think that society should permit the use of drugs for recreational purposes. After all, over twenty years of troop sweeps, police actions and military rhetoric, the evidence is all around us. The war on drugs has flopped. It has been more then ineffective and has actually made things worse. We as American citizens have to wake up and realize that there will never be a â€Å"drug free† utopia that we have been promised. People will always be willing to experiment with their bodies and use drugs no-matter the cost involved in doing so.

We have to remember that whether someone wants to do drugs is there personal choice and in the end; there’s alone. In this situation we need to take action by allowing our pharmaceutical companies the ability to produce safer drugs with the same effects as those on the streets, this intern would allow American companies to profit here and around the world, drug dealers to loose their clout and to take the immediate burden of the tax payers of this country. The immediate effect of a legalized drug market would be increased safety for drug users. All clean and natural drugs such as marijuana, cocaine and heroin are pathologically harmless if taken in appropriate doses and not tampered with in a lab before hand. A regulated drug market would do just this and provide such safety for drug users as consistent doses, lowering the likelihood of overdoses with some drugs. Clear labeling, instructions, and warnings like those listed by the surgeon general on a pack of cigarettes would result in safer usage. The legalization of drugs would allow pharmaceutical companies to profit by allowing them to research and eventually create safer drugs that produce similar side effects to the Page 4. current illegal ones. At the same time there would be significant tax revenues that would be included into the big picture. Overall these new

Civil Rights And Social Integration Of African Americans

During the 20th century there were numerous riots, protests, and boycotts fighting for the equality and social integration of African-Americans. Some of the stories of individuals endeavoring for their freedom have gone down in history—resulting in laws being altered, regulations being revised, and unimaginable boundaries being broken. Sadly, in order to establish justice in this world, violence and death usually occur due to conflicting ideals. In Southern Los Angeles, even after African-Americans were issued their â€Å"Civil Rights,† underlying racism constructed barriers such as â€Å"racial restrictive covenants† that ensured that blacks were still not welcome there. The two biggest social disturbances that have taken place in the West have taken place in Los Angeles—where unemployment, overcrowding, poverty, and segregation have become increasingly prevalent. The first of these social disturbances is the Rodney King riot of 1992 and the second is the Watts riot of 1965. The racial bigotry, which was backed by the racial restrictive covenants and racial discrimination of LAPD throughout Southern Los Angeles; as well as the events that sparked the Rodney King riot and the Watts riot; clearly illustrate the racial segregation and the overall struggle that African-Americans faced during the 20th century.

Published on March 8, 1775, On African Slavery by Thomas Paine was available for the public ten months and two days before Common Sense. Despite the difference in publishing dates these two written works provide numerous similarities. For example, On African Slavery is addressed â€Å"To Americans:† (Paine 1) and Common Sense is similarly â€Å"Addressed to the Inhabitants of America† (1). Furthermore, both written works address Paine’s belief that all men are â€Å"originally equals† (71). In Common Sense, Paine uses this belief to discuss hereditary succession and monarchy, while in On African Slavery Paine uses this belief as a foundation of his argument against slavery. Hereditary succession is also discussed in On African Slavery, when addressing†¦show more content†¦Make specific references using direct quotations. The use of the word â€Å"common† may be found throughout the two works by Paine as well as the Declaration. For example, the Declaration of Independence uses â€Å"common† when referring to â€Å"common kindred† (Jefferson 4) and Common Sense uses â€Å"common† throughout the book when discussing a â€Å"common cause† (Paine 66), â€Å"common period of life† (66), and â€Å"common interest† (67). Furthermore, â€Å"common† may be found in On African Slavery when discussing a â€Å"common Lord† (1) and â€Å"common Justice and Humanity† (1). Another example of similar phrasing throughout Paine’s two works (Common Sense and On African Slavery) and the Declaration are found when condemning a King. Common Sense condemns the King multiple times, one example being â€Å"That the King is not to be trusted without being looked after,† (Paine 69). Similarly, the Declaration also condemns the King by explaining â€Å"The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in dire ct object the establishment of an absolute Tyranny over these States.† (Jefferson 2). Furthermore, On African Slavery explains â€Å"...that these inoffensive people are brought into slavery, by stealing them, tempting Kings to sell subjects, which they have no right to do†¦Ã¢â‚¬  (Paine 1).

Anesthetics Essay Example For Students

Anesthetics Essay Anesthesia is a partial or complete loss of sensation or feeling induced by theadministration of various substances. For many decade, people have used one formof an anesthetic during surgical procedures. Some people also use some of theseanesthetics as recreational drugs, e.g. laughing gas (a.k.a. Nitrous Oxide). Theterm anesthetic literally means without feeling. There are manydifferent types of anesthesia, but they are usually put into three groups. Thesegroups are gene- ral anesthetics, local anesthetics, and spinal anesthetics. Ageneral anesthetic causes a complete loss of consciousness. They are used whenhaving a serious operation or in the case of an emergency operation. It works tothe surgeons advantage because the anesthesia reacts with the body in a matterof seconds. There are two different ways in which general anesthetics areadministered, they are intravenous and inhalation. The most popular procedure isintravenous. This is where the anesthetic is put into the body by way of aneedle in the vein, which is usually located in the hand or elbow. Althoughintravenous is more popular, it is usually used by itself during shortprocedures. In the case of longer procedures, intravenous anesthesia is alsoaccompanied by inhalation anesthesia. Inhalation anesthesia is administered byway of a mask and in the form of gas. Usually during long procedures, the maskwill remain on while the fluids from the intravenous anesthesia work throughyour body. The second group of anesthesia is local anesthesia. Local anesthesiais used when a doctor wants to numb a certain part of the body while youmaintain total consciousness. Local anesthetics are usually administered througha gel or cream on the surface of the skin, but can also be injected underneaththe skin, e.g. lidocane. If the anesthetic is placed on the surface of the skinthan the numbing effect should take place within a few seconds. If injectedunderneath the skin, it can take up to a few minutes to take effect. Both for msof local anesthesia are used when dealing with minor surgery such as dentistry,etc. The third and last group of anesthetics is the topical group. This group isassociated with childbirth, gynecological procedures, and spinal operations. Aspinal injection gives relief to pain, but at the same time allows for totalconsciousness. Usually the syringe is injected into the epidural layer of thespine. The effects of the spinal injection can be felt within minutes of theinjection. As I have already discussed, there are three different methods ofdistribution among anesthetics, inhalant, intravenous, and infusion. An inhalantis an anesthetic in the form of a gas which is administered by way of a gasmask. Intravenous anesthesia is administered by way of a needle into the vein. Infusion anesthetics are administered by way of a catheter. These three methodsoperate in four steps. The first of these steps is premedication or inductionstage. This step involves the nurse or practitioner to administer a form of asedative or muscle relaxant. This step is not always required, only when havingmajor surgery. The second stage is when the actual anesthesia is administered. The patient falls into a deep, pleasant state of unconsciousness. The thirdstage is when the drug is in full effect. The patient now experiences a loss ofconsciousness, although the patients reflexes still remain active and breathingis a little irregular. In the last stage, the fourth stage, the patient istotally unconscious. Muscels are fully relaxed and breathing becomes regular andquiet. Anesthesia has a long history which started in the middle 1700s. In1769, an English chemist, Joseph Priestley discovered the first recognizedanesthetic, nitrous oxide. Nitrous oxide is more commonly known as laughing gas. Although the gas was discovered in 1769, it wasnt until 1844 when an Americandentist by the name of Horace Wells, first put the nitrous oxide to use during adentistry procedure. The wonderful world of anesthesia was growing and becomingmore and more popular throughout the United States as well as in England. Thenext important discovery took place in 1829. In 1829, an American, MichealFaraday reported that the inhalation of ether caused a person to go into a stateof unconsciousness. Using ether as an anesthetic was not very popular, though. It was first used in 1842 when, an American doctor, Crawford W. Long removed atumor off of the neck of one of his patients. The second recorded use of etherwas by the American dentist, Thomas Green Morton in 1846. Morton along with thehelp of Charles Thomas Jackson, an American chemist, devel- oped a technique forpainless tooth extraction with the assistance of diethyl ether. In 1831, anAmerican physician and chemist, Samuel Guthrie was the first to discoverchloroform and its uses. The first to use chloroform during a surgical procedurewas Sir James Y. Simpson. Simpson was a Scottish obstetrician whom was notsatisfied with the action and reaction of ether. Simpson was the first to adoptchloroform as a useful anesthetic in surgical procedures. In 1884, Sigmund Freudwas the first to report cocaines anesthetic properties. An Austrailianphysician, Karl Koller, took this report of cocaine as an anesthetic and appliedit to surgical procedures. Kollers surgical procedure was even more impor tantbecause it was the first procedure to take place while using what we now calllocal anesthesia. Cocaine was the first local anesthesia to bediscovered and used in a surgical procedure. William Stewart Halsted, a profesorof surgery at John Hopkins University in Baltimore, was the first to use cocaineto anesthetize whole areas of the body by directly injecting the cocaine intothe nerve. In 1898, Karl Gustav Bier injected cocaine into vertebral canal andobtained paralysis of the lower extremities of the body. He used this method insurgical procedures. Since then this procedure that he discovered is know asspinal anesthesia and is widely used today. At around 1901, J.L. Corning usedcocaine to produce a useful spinal anesthetic, which in turn produced twoimportant cocaine derivatives, novocaine and procaine. Many other importantanalgesics and their uses came about between 1800 to 1900. Ethyl chloride whichwas introduced to us in 1848, was too short lived. Surgeons needed an anesth-eti c that was non-toxic and non-inflammable. So in 1929, cyclopropane wasintroduced to the medical world, but soon enough the medical world found outthat the drug was inflammable. In 1934, trichloreth- ylene was first used. Thisdrug on the other hand came along with two advantages. It reduced the awarenessof pain while maintaining full consciousness, which made the drug ideal forchildbirth use. In 1874, Ore of Bordeaux, was the first to achieve anintravenous anesthesia. He used Chloral to achieve this intravenous anesthesia. Examining The Project Of The Channel Tunnel Construction EssayXenon exhibits all the analgesic properties to eventually become an importantanesthetic in the medical world. Many advances have also been made tointravenous anesthetics as well. One of the newest types of intravenousanethesia is propofol. It is the newest intravenous drug to date. It wasintroduced to the medical world in 1984. Since then there have been incredibleadvances made in the administration, distribution, and maintenance of the drug,propofol. The drug has very few side effects, which include a mere nausea anddrowsiness. It has a very fast recovery and induction. One major disadvantage,though, is that it is difficult to acheive the desired plasma concentration bymanual control of the infusion rate. In order to maintain a constant flow theinfusion rate must be changed frequently. This is when the target controlledinfusion rate technique takes place. Target controlled infusion is what allowsthe anesthesiologist to set a desired plasma concen- tration, which the softwareinside the infusion pump produces rapidly, but safely by controlling theinfusion rate according to complex, but standard pharmacokinetic equations(basically medical equations). Remifentanil is a new potent, yet synthetic opiodthat is ideally suited for infusion during anesthesia. Unlike other opiods,remifentanil contains a methyl ester in its structure which causes a rapidmetabolism of the drug within the body. Remifentanil is now used as aneuroanesthetic and in the future will probably be used as a cardiac andcardiovascular anesthetic. Many advances have also been made in the medicalworld concerning local anesthetics. Amongst these local anesthetics, the mostpopular and up to date are bupivacaine and ropivacaine. Bupivacaine isfrequently used in postoperative pain releif. Induction to this anesthetic israpid and lasts very long. It can last for several hours depending on the dosegiven. The bupivacaine molecule exhibits stereoi somerism in each one of the twoenantiomers, which are R(+)bupivacaine and S(-) bupivacaine. The R(+) form ofbupivacaine is 3-4 times more likely to cause cardiovascular toxitity in rabitts,sheep, and humans. Ripovacaine is very similar to bupivacaine, but it is onlyprepared as S(-) ripovacaine isomer. Ripovacaine was proven safer thanbupivacaine in many clinical studies. Anesthesia has an unusual property. It isknown as the cutoff phenom- enon. The cutoff refers to the loss of anestheticpotency in the homologous series of alkanes and their derivatives when theirsize becomes too large. Apparently the potency increases with the length of thechain until the chain reaches fourteen carbons. At the fourteen carbon mark, theanesthetic has no potency whatsoever. The anesthetic potency increases rapidlyfrom a two carbon chain (ethanol) up to a ten carbon chain (decanol). From theeleven carbon chain to the thirteenth carbon chain the potency remains the same. When the carbon chain finally reaches the forteenth carbon, the potency suddenlydisappears. Scientists predict that this happens because the binding site is notlarge enough to accomodate long chained alcohols or because of the low watersolubility of longer 1- alkanols limits their access to the action sight. Scientists studied this through changing the 1- alkanol series to DPPC (dipalmitoyl-L-a-phosphatidylcholine). They did this through a procedure known ashydrogen bonding. Through hydrogen bonding transitional phases occured. In thesephases scientists proved that in between the transition of temperature, whichalso changed the state of matter, there was a certain point at which there wasno affect on the DPPC. Scientists also learned that the primary action site foranesthetics are the macromolecules of water. In conclusion C2-C10 are known asanesthetics and C14+ are known as nonanesthetics. In anesthesia, highpolarizability causes hydrogen bond breaking which causes anesthesia to work(e.g. cyclopropane). Also increased hydrophobicity along with relaxaion ofmembranes and proteins cause anesthesia to work. Anesthetics have manyadvantages. They are great in eliviating pain before, during, and after asurgical procedure. They also make the procedures much more easier. Anestheticsgive a desire d affect which is good because it helps us as a patient to relaxand feel calm and pleasant. Anesthetics have been around since the begging ofthe 1700s. Scientists have gathered a tremendous amount of informationconcerning anesthetics. Many advancements have been made and will continue to bemade. Throughout history man has searched for a way to stop pain. Whether it bea sore tooth or a broken limb, man has tried many different things to try and toget rid of that pain that he feels. The most modern way to eliviate pain isthrough the use of anesthetics. Although many of them have side effects, theyare improving and as long as our world and economy keep moving ahead andtechnologically advancing, we will be able to perfect all of the anesthetics. Inthe future there will prob- ably be new techniques used to administer anddistribute anesthetics, but for now these drugs seem to be doing the trick. Aswe enter into this new millennium, I hope to see more advances concerninganesthesia in this colorful world that we call the U.S. BibliographyAnesthesia: The Curing Sleep. Swift, W. Bradford.
