Fluid intake should be increased while taking antigout drugs and the urine should be alkaline discount sarafem 20 mg without prescription. Foods rich in purine generic sarafem 10mg without prescription, including wine generic sarafem 20 mg on line, alcohol, organ meats, sardines, salmon, and gravy should be avoided. The body releases hista- mines, kinins, and prostaglandins that force fluid and white blood cells to the site of the injury to stimulate nerve endings and clean the area so it can heal. The site of the injury becomes red, swollen, and warm and loses its normal function. The vascular phase is where blood vessels dilate and become permeable so fluid and white blood cells can leave the vessel. Anti-inflammatory medication reduces the inflammatory process which may allow the patient to go about normal daily activities while the tissue heals. There are three categories of anti-inflammatory medications: analgesic, to relieve pain; antipyretic, to reduce fever; and anticoagulants, to inhibit blood clotting. You learned in this chapter that inflammation is not an infection although inflammation frequently occurs when a patient becomes infected with a micro- organism. Inflammation occurs in response to tissue injury whether it is from an injury or an acute or chronic disease such as rheumatoid arthritis or gout. You’ll learn about infection and fever and antimicrobial medication in the next chapter. Anti-inflammatory medication stops the production of prostaglandins resulting in a decrease in the inflammatory process. The choice of medications for relieving headaches are aspirin, acetamin- ophen, and ibuprofen. Other times, symptoms are caused by malfunc- tioning parts of your body such as the pancreas in the case of diabetes. You’ll remember from your courses on anatomy and physiology and microbiology that a micro- bial is a tiny organism—such as bacteria and viruses—that can enter the body and make you sick. The immune system produces antibodies that seek out, attack, and kill micro- bials. However, this natural defense isn’t sufficient for some patients who need to call in the cavalry. Pathogens enter our body in a variety of ways such as a cut or in food that we ingest. Our body reacts with an inflammatory response that dilates blood ves- sels so they become permeable. Nerve endings are stimulated and send a message to your brain that there is something wrong. You know when this happens because the infected area turns red, swollen, and it hurts. Other infections affect an organ or entire system of your body, which is referred to as a systemic infection or septecemia. Medication—A Formidable Defender Your natural defense against bacteria is a phagocytic response. Cells in your body engulf a pathogen, basically eat it and remove the injured tissue. For example, an antibiotic used to kill bacteria that causes a urinary tract infection will also kill the flora in your intestine that are used to help digest food. Patients are also treated with medication that eases the symptoms of inflam- mation but doesn’t kill microbials. Prostaglandins are chemical mediators that bring about the inflammatory response by vasodilatation, relaxing smooth muscle, making capillaries perme- able, and sensitizing nerve cells within the affected area to pain. It is also an antipyretic to lower body temperature and it is an anticoagulant that inhibits the formation of platelets. Sulfonamides are bacteriostatic, which means they stop the growth of bacteria, but do not kill bacteria. Penicillin, the first antibiotic, is a bacteriocidal and kills bacteria using lysis, which explodes the bacteria into parts. Today there are many synthetic and semi-synthetic antimicrobials on the mar- ket that stop some bacteria from growing and kill other bacteria. For example, chloramphenicol is bacteriostatic and stops most bacteria from growing while it is bacteriocidal and kills S pneumoniae and H influenza in cerebral spinal fluid. Tetracycline is also bacteriostatic and bacteriocidal; in small concentrations it stops the growth of bacteria and in high concentration it kills bacteria.

Similarly purchase sarafem 10mg, eliminations often favour the more stable trans-product over the cis-product 10mg sarafem with amex, described as stereoselectivity buy discount sarafem 20 mg on line. The E2 elimination can be an excellent synthetic method for the preparation of alkene when 3 alkyl halide and a strong base, e. The rate is related to the concentrations of the substrate and the base, giving a second order rate equation. If there are two or more possibilities of adjacent hydrogen atoms, mixtures of products are formed as shown in the following example. The partial p bond in the transition state requires the parallel alignment or coplanar arrangement of the p orbitals. When the hydrogen and leaving group eclipse each other (0 ), this is known as the syn-coplanar conformation. H X H X B:− − B: H H X X syn-Coplanar (0o) syn-Elimination anti-Coplanar (180o) anti-Elimination When the leaving group and hydrogen atom are anti to each other (180 ), this is called the anti-coplanar conformation. The anti-coplanar con- formation is of lower energy, and is by far the most common. In the anti-coplanar conformation, the base and leaving group are well sepa- rated, thus removing electron repulsions. The syn-coplanar conforma- tion requires the base to approach much closer to the leaving group, which is energetically unfavourable. It is stereospecific, since it prefers the anti-coplanar transition state for elimination. The (R,R) diastereomer gives a cis-alkene, and the (S,R) diastereomer gives a trans-alkene. In a chair, adjacent axial positions are in an anti-coplanar arrangement, ideal for E2 eliminations. Two types of substitution reaction can occur: nucleophilic sub- stitution and electrophilic substitution. The term electrophile literally means ‘electron-loving’, and is an electron- deficient species that can accept an electron pair. A number of nucleo- philic substitution reactions can occur with alkyl halides, alcohols and epoxides. However, it can also take place with carboxylic acid deriva- tives, and is called nucleophilic acyl substitution. Electrophilic substitution reactions are those where an electrophile dis- places another group, usually a hydrogen. The À À nucleophile (Nu: ) displaces the leaving group (X: ) from the carbon atom by using its electron pair or lone pair to form a new s bond to the carbon atom. Thus,therateofanS1N reaction depends only on the concentration of the alkyl halide. First, the CÀÀX bond breaks without any help from the nucleophile, and then there is quick nucleophilic attack by the nucleophile on the carbocation. When water or alcohol is the nucleophile, a quick loss of a proton by the solvent gives the final product. For example, the reaction of t-butylbromide and methanol gives t-butyl methyl ether. Thus, the rate depends on carbocation stability, since alkyl groups are known to stabilize carboca- tions through inductive effects and hyperconjugation (see Section 5. The leaving group should be stable after it has left with the bonding electrons, and also be a weak base. The leaving group starts to take on partial negative charge as the cation starts to form. Solvent effects Protic solvents are especially useful since the hydrogen bonding stabilizes the anionic leaving group after ionization. For example, the reaction of (S)-2-bromobutane and ethanol gives a racemic mixture, (S)-2-butanol and (R)-2-butanol. H C (Inversion) 3 C2H5 Attack from bottom face The nucleophile may attack from either the top or the bottom face. If the nucleophile attacks from the top face, from which the leaving group departed, the product displays retention of configuration. If the nucleophile attacks from the bottom face, the backside of the leaving group, the product displays an inversion of configuration. Often complete racemization is not achieved since the leaving group will partially block one face of the molecule as it ionizes, thus giving a major product of inversion. Rearrangements occur when a more stable cation can be produced by a 1,2-hydride shift.

In folk culture books were thought to contain secret knowledge otherwise unobtainable in the oral medical tradition sarafem 10 mg with visa. Cultural exchange We need to be aware of the non-European influences on the history of Euro- pean medicine buy 20mg sarafem. The importance of Arabic science and medicine during the mediaeval period is well recorded buy sarafem 10 mg free shipping. In Europe much knowledge of classical medicine was lost for centuries after the collapse of the Roman Empire, and so the Arabic world became the main repository of ancient Greek and Roman medical theory. Most of Galen’s writings had been translated into Arabic by the tenth century, and it was largely thanks to mediaeval Arab and Jewish scholars in Spain and Constantinople that Galenic theory came to dominate European medicine until the eighteenth century. As well as this crucial role in the development of orthodox western medicine, the Moorish populations of Spain, and Jewish communities across Europe, maintained distinctive folk medical traditions, the practitioners of which were also consulted by Christians. During the sixteenth century the secular authorities and the Inquisition in Spain made a concerted effort to suppress Muslim physicians and Arabic texts, denigrating Arabic–Galenic medicine. As a consequence, over the next few centuries Moorish medical practitioners largely operated within the magical–medical context of curandismo, prac- tising herbalism, using charms, and curing and diagnosing based on the Islamic tradition that diseases were embodied by demons or djinns. As a study of folk medicine in Murcia in south-eastern Spain observed, the Latin, Moorish and Jewish medical traditions in the region’s folk belief and practice are so entwined that it is a difficult task to disentangle them. Studying folk medical knowledge provides one of the few ways of mapping the cultural experience of these different migrant populations and their adaptation to new environments. They are the ancestors of Genoese migrants who, in the sixteenth century, colonised the small island of Tabarka off the Tunisian coast. After two centuries they were forced to flee to Sardinia where they founded their own communities. Researchers recently studied their folk phytotherapy and found that nothing significant remained of their north African experience. But, while they had evidently adopted Sardinian herbal medical traditions, their Genoese heritage was still apparent in their names for local plants. In eighteenth-century Portugal, healers of African descent, who were brought to the country as slaves either directly from Africa or more commonly from Brazil, attracted considerable renown for their curative powers. The Portuguese Inquisition tried between 15 and 20 healers in the period, among them Maria Grácia, a 40-year-old Angolan slave owned by a wool contractor in Evora. She was tried in 1724 for curing witchcraft-inspired illnesses and the ‘malady of the moon’. Her Christian charms did not owe anything to her Angolan homeland, however, but the exoticism of her skin colour and African heritage lent her and other Luso- African healers, women in particular, popular esteem among the Portuguese for their possession of occult knowledge. Research has recently been conducted, for example, on folk medicine among Thai women in Sweden, Surinamese immigrants in Amsterdam and Sikh 36 | Traditional medicine communities in London. A study of traditional medicines used by a Pakistani migrant community in Bradford, England, reveals that, although most of the herbal remedies used are not known in the western tradition, the interviewees subscribe to the Unani medical tradi- tion, which developed in mediaeval Persia but was based on ancient Greek humoral theory (Unani means Greek). Even before European colonial expansion from the sixteenth century onwards, ingredients had long arrived from the east. Cloves, mace and nutmeg were being traded across Europe by the thirteenth century. In nineteenth-century England the popularity of nutmeg as a carminative for flatulence and dyspepsia created a trade in portable nutmeg holders and graters. These were made of silver for the wealthy, while rural craftsmen sold little wooden boxes in the form of an acorn and the like for the humble. Now little used in Europe, dragon’s blood, the blood-red resin of various non-European trees, was used in the ancient world for medicinal purposes and its use has spread to folk medical traditions around the world. One of the remedies for relieving the possessed suggested by Florian Canale, an early modern Italian exorcist, involved a distillation including dragon’s blood, ground glass, wax and turpentine. Editions of Aristotle’s Compleat Master-piece, for instance, provided several remedies for ‘spitting of blood’, usually associated with tuberculosis, including one that mixed dragon’s blood with ‘frogspawn water’, ‘plantain water’ and syrup of roses. It became a staple ingredient of chemists and druggists in the nineteenth century, although often purchased by the poor for use in love divination rituals rather than medicine. But, as numerous studies of folk medicine in contemporary urban societies in the Americas, Asia and Africa have shown, this is certainly not the case. Britain was the first industrial urban nation and, although little work has been done on the issue, there is sufficient evidence that folk medicine served an important function in this new way of life.
