It is used for treating stomach ulcers, inflamed intestine, and also as a pre-operational drug for inhibiting excess stomach secretion. Reacting this with cyclohexylmagnesiumbromide gives 4-(β-cyclohexyl-β-hydroxyphenethyl)-1,1-piper- azine (14. Anticholinergic Drugs Hexocyclium inhibits muscarinic action of acetylcholine on postganglionic parasympathetic effector regions. It is believed that they do not affect the synthesis, release, or hydrolysis of acetylcholine. Their medicinal efficacy is manifest by the reduction or removal of motor disturbances caused by damage to the extrapyramidal system. They reduce rigidity, and to a somewhat lesser degree, akinesia, and they have little effect on tremors. The therapeutic value of these drugs is relatively small, and they are used either in combination with levodopa, or in cases of minor Parkinsonism. These drugs have weaker anticholinergic activity than atropine; however, they have a significantly more expressed antispastic action. Dicyclomine: Dicyclomine, diethylaminoethyl ester of 1-cyclohexylcyclohexanecarboxylic acid (14. According to the first, benzyl cyanide undergoes alkylation by 1,5-dibromopentane, which forms 1-cyano-1-phenyl-cyclohexane (14. This undergoes alcoholysis, which gives the ethyl ester of 1-phenyl-1-cyclohexa- necarboxylic acid (14. This undergoes alcoholysis, forming the ethyl ester of 1-bicyclohexanecar- boxylic acid (14.

Mydriatics of the tertiary amine series Anticholinergic drugs of the tertiary amine series (cyclopentolate, tropicamide) also are used locally as mydriatics for causing cycloplegia and mydriasis. They are primarily used as adjuvant drugs for eye examinations and other diagnostic procedures before, during, and after opthalmological interventions. Cyclopentolate: Cyclopentolate, 2-(dimethylamino)ethylic ester of 1-hydroxycyclopentane- α-phenylacetic acid (14. Synonyms of this drug are mydrilate, cyclogyl, cyclomydril, pentolair, and others. Synonyms of this drug are mydrin, mydriacyl, mydriafair, tropicacyl, tripatar, and others. Depolarizing ganglioblockers such as nicotine initially stimulate postganglionic receptors, and then they block subsequent activation of the receptor, thus preventing repolarization of the postsynaptic membrane. The pharmacological effects of nicotine are very diverse and largely depend on the dose, exposition, and physiological condition of the individual. Antidepolarizing ganglioblockers such as the clinically effective drugs mecamylamine and trimethaphan act as competitive antagonists to acetylcholine on postganglionic recep- tive regions. Their main action consists of reducing vessel tonicity, expressed dilation of vessels, and reducing peripheral resistivity. Venous dilation causes congestion of blood, and therefore a reduction in the quantity of returnable blood to the heart and a reduction in cardiac output. At the same time, ganglioblockers cause orthostatic hypotension, which is an extremely undesirable side effect. They are drugs for lowering blood pressure; however, they are rarely used because of a large number of side effects such as tachycardia, mydriases, reduced gastrointestinal tract activity, urine retention, dry mouth, and others. Because their actions are so broad, including blocking of sympathetic and parasympa- thetic systems, their therapeutic use has been largely supplanted by more specific drugs.

To apply X-ray crystallography to drug molecules acne medication prescription order decadron 0.5 mg on line, the compound must first be crystallized into a solid form; within this crystalline solid acne hoodie discount decadron 4 mg on line, many drug molecules lie stacked together skin care trends order generic decadron online. When X-rays strike a crystalline solid, the X-rays interact with electrons in the atoms and are scattered in different directions, with varying intensities due to interference effects. When this interference is constructive, in-phase waves combine to produce a wave of greater amplitude that can be indirectly detected by exposing a spot on a photographic film. When the interference is destructive, the waves cancel each other such that a decreased X-ray intensity is recorded. These interference effects arise because the different atoms within the molecule of the crystalline solid scatter the X-rays in different directions. This scat- tered radiation produces maxima and minima in various directions, generating a diffrac- tion pattern. The quantitative aspects of the diffraction pattern are dependent on the distances between planes of atoms within the crystal and on the X-ray wavelength; these relationships may be mathematically analyzed by means of the Bragg equation nλ = 2d sin θ (1. By analyzing the angles of reflection and the intensities of diffracted X-ray beams, it is possible to determine the location of atoms within the molecule. Thus, determining the molecular structure of a crystalline solid is equivalent to determining the structure of one molecule. This in turn provides detailed information about the structure of the drug molecule (i. Perhaps first and foremost is the work of Dorothy Hodgkin who transformed X-ray crystallography into an indispensable scientific method. Her first major achievement was the crystallographic determination of the structure of penicillin in 1945; in 1964 she received the Nobel Prize in Chemistry for determining the structure of Vitamin B12. Myoglobin and hemoglobin were the first proteins (in 1957 and 1959) to be subjected to a successful X-ray analysis. Kendrew and Max Perutz at Cambridge University; they received the 1962 Nobel Prize. Watson, Crick, and Wilkins received the 1962 Nobel Prize in Medicine for this work; Franklin was already deceased. Clearly, in its infancy X-ray crystallographic determination of molecular structure was a challenging task. Automated X-ray diffrac- tometers, direct methods for structure determination, and increasingly sophisticated computers and more efficient software have permitted X-ray crystallography of small drug molecules to become almost routine. Such X-ray studies provide valuable experimental information about the precise dimensions of drug molecules. In addition to providing structural insights into small drug molecules, X-ray crystallography can also provide data concerning drug–macromolecule interactions when the drug and its receptor are co-crystallized. The spin number of a nucleus is controlled by the number of protons and neutrons within the nucleus; the nuclear spin varies from element to element and also varies among isotopes of a given element. A nucleus with a spin quantum number I may take on 2I +1 energy levels when it is placed in an applied magnetic field of strength H. The amount of energy separating these levels increases with increasing H; however, the amount of energy separating adjacent levels is constant for a given value of H. The specific amount of energy separating adja- cent levels, ∆E, is given by E = (Hγ h)/(2π) (1. Since the exact value for ∆E is related to the molecular environment of the nucleus being excited, there now exists a way of relating the value of ∆E to the molec- ular structure; this enables the molecular structure to be determine. When such a nucleus (or an unpaired electron) is put into a strong mag- netic field, the axis of the rotating atom will describe a precessional movement, like that of a spinning top. The precessional frequency ω0 is proportional to the applied magnetic field H0: ω0 = γH0, where γ is the magnetogyric ratio, which is different for each nucleus or isotope. Since the spin quantum number of the nucleus can be either +1/2 or −1/2, there are two populations of nuclei in any given sample, one with a higher energy than the other. These populations are not equal: the lower-energy population is slightly more abundant.

Corticosteroids are not bronchodilators acne rash decadron 1 mg order on line, and it is reasonable to think that their action is simply relayted to the anti-inflammatory immunodepressive effect of corticosteroids acne neonatorum cheap decadron online amex, which is quite positively manifested in the course of relieving bronchial asthma skin care nz decadron 8 mg discount. They are widely used for obstructive diseases of the respiratory tract; however, they are not used for severe bronchial asthma attacks. A number of side effects cased by their systematic use limit their use to some degree as drugs for treating bronchial asthma. It is highly likely that these drugs act by raising the level of cyclic adenosinemonophosphate, an excess quantity of which is formed as a result of adenylate cyclase activation. The result of β2-adrenoreceptor agonist action is relaxation of smooth musculature, and in the given case, smooth musculature of the bronchi, and simultaneous inhibition of allergogenic mediator release. One of the first β-adrenoreceptor agonists used both currently and in the past as a bron- cholytic is epinephrine or adrenaline, isoproterenol, and especially ephedrine. In treatment and prevention of obstructive respiratory tract diseases, other β-adrenoreceptor agonists also are used, such as isoetharine, terbutaline, albuterol, metaproterenol, and also those described in this section—fenoterol (23. Synthesis and pharmacological properties of the first six drugs mentioned, epinephrine (adrenaline) (11. This is reacted with 2-benzylamino-1-(4-methoxyphenyl)-propane, giving the corresponding tertiary amine 23. Hydrolysis of the acetyl group of this product and removal of the protective ben- zyl group by hydrogen reduction using a palladium on carbon catalyst gives a secondary amine 23. This is reacted with hydrobromic acid, which cleaves the ether bond in the benzene ring, producing phenol derivative 23. Finally, reduction of the carbonyl group with hydrogen gives the desired fenoterol (23. It dilates bronchi and blood ves- sels, has a pronounced tocolytic action, lowers contractile activity and reduces uterus tonicity. Selective oxidation of the 6-hydroxymethyl group using manganese peroxide gives 3-benzyloxy-2- hydroxymethylpiperidine-6-aldehyde (23. Condensation of this with nitromethane gives the corresponding nitromethylcarbinol 23. Drugs for Treating Respiratory System Illnesses 2-bromobutyric acid chloride at the fifth position of the quinoline system, which gives the compound 23. Drugs that speed up lysis of already formed blood clots are called thrombolytics or fibrinolytics. Drugs that facilitate reduction and stoppage of bleeding are called hemostatic drugs. Coagulation and fibrinolytic processes are very important protective physiological mechanisms of the organism, and only a very fine regulatory interaction between them provides the required homeostatic condition of the vascular system. In normal conditions, microscopic blood clots are often necessary for restoration of damaged areas of vessels. During this, the damaged vessel is restored by renewing its endothelial surface, and insol- uble clots formed are effectively removed by the fibrinolytic system by way of proteolytic digestion into soluble fragments. The process of blood clot formation and their subsequent lysis is a very complex feature that depends on a number of substances (coagulation factors—fibrinogen, prothrombin, tromoplastin, calcium, antihemophylin factor, and others) that exist in the plasma, blood cells, and to a lesser degree in other tissues. The process of thrombocyte aggregation and its inhibition is very strictly regulated by a thromboxane–prostacyclin system. Thromboxane A2 strengthens aggregation, while prostacyclin (prostaglandin I2) inhibits aggregation. Prostaglandin E2—collagen of vascular walls, thrombin, adenosine diphos- phate, serotonin, and catecholamines are all aggregation stimulants. Prostaglandin E1, adenosine monophosphate, adenosine, methylxanthines, serotonin antagonists, heparin, and others are aggregation inhibitors. Disturbances in endogenic control over coagulation and fibrinolytic processes can have severe consequences. On one hand, initiation of unlimited coagulation can lead to throm- bosis, and subsequently, to ischemia, stroke, or death. Therefore, depending on the character of the abnormality, which can result in clinical problems of various difficulties, both condi- tions require correction. Anticoagulants, antiaggregants, thrombolytics, and hemostatics are used for this purpose. Therapy using anticoagulants is first and foremost directed at preventing the formation of clots in blood ves- sels, which are the main cause of death in thromboembolic diseases.

Disaccharides When two cyclic monosaccharides (acetal bonding) are coupled by means of a glucoside bonding a disaccharides arises. Disaccharides are commonly present in nature and form important components of foods. Disaccharides are also important in the formation of polysaccharides and monosaccharides. The organic chemical name is Alpha-D- Glucopyranosyl-(1->2)-Beta-D-fructofuranoside. During the digestion, saccharose is broken down by the enzyme invertase in glucose and fructose. This enzyme is produced in the small intestine where the breakdown of sucrose occurs. The known sugar from the daily life consists of saccharose, just as powdered sugar and sugar syrup. The word alpha, in the name of the alpha 1,4 bond between the two glucose units, indicate that the two units are in a straight area. The numbers 1,4 indicate that the bond is present between the carbon atoms 1 and 4. The organic chemical name is Beta-D- Galactopyranosyl-(1->4)-Alpha-D-Glucopyranose. The word Beta , in the name of the bond between the two monosaccharides units, indicates that the two units are not in a straight area, they are slant on each other. Lactose intolerance Lactose is broken down in the digestion to galactose and glucose by the enzyme lactase. In contrast to children, there is a large group of adults in the world that can not produce the enzyme lactase. After drinking milk, lactose accumulates in the lumen of the intestine because there is no mechanism to take up this disaccharide. Lactose intolerance is a genetic variation that mostly presents itself in adolescent or in adult life. Lactose intolerance is prevalent in 3% of Danish people, and in 97 % of Thai people. The ability of people to break down lactose also in maturity appears to have been developed since people started to domesticate cow cattle. Polysaccharides Polymers are biomolecules composed of units in which we can recognize the monosaccharides. Natural textile fibre such as linen (flax), cotton and viscose (artificial silk) consist of cellulose. Humans do not have an enzyme that is able to break down the beta bonds in cellulose. Cellulose and other indigestible compounds form the dietary fiber, which are important in our digestive system. In this form, there are branchings in the form of alpha-1,6-bonds that occur once every thirty units. Starch is broken down in individual glucose units by the action of the enzyme amylase. It consists of glucose units that are coupled by Alpha-1,4-bonds, with branchings as alpha-1,6-bonds.

Chirality (chemistry) Two enantiomers of a generic amino acid (S)-Alanine (left) and (R)-alanine (right) in zwitterionic form at neutral pH A chiral molecule is a type of molecule that lacks an internal plane of symmetry and has a non-superimposable mirror image. The feature that is most often the cause of chirality in [1][2] molecules is the presence of an asymmetric carbon atom. The term chiral (pronounced /ˈkaɪrəl/) in general is used to describe an object that is non- superposable on its mirror image. Achiral (not chiral) objects are objects that are identical to their mirror image.

Other factors that affect thermodynamic activity of the solution at the skin surface (e acne dermatologist cheap decadron 4 mg amex. Vehicle influence cannot be overstated; for a specific concentration of chemical, thermodynamic activity may vary by 1000-fold from one vehicle to another (6). Other factors that affect percutaneous absorption include condition of the skin (7), age, surface area to which the material is applied (8), penetrant volatility, temperature and humidity (9), substantivity, and wash-and-rub resistance to removal from the skin and binding to the skin (10). Once a chemical has gained access to the viable epidermis, it may initiate a local effect, be absorbed into the circulation and produce an effect, or produce no local or systemic effects. The viable epidermis contains enzymes capable of metabolizing exogenous chemicals (11), including a substantial cytochrome P450 system, esterases, mixed-function oxidases, and glucuronyltransferases. Early studies conducted in vitro using whole skin indicated that enzymatic activity in skin was only a fraction of the activity of the liver. However, when the surface area of the epidermis is taken into account, then enzymatic activities of the epider- mis can range from 80% to 240% of those in liver (12). Because the analytical techniques to measure the chemi- cal are not always available and because some chemicals may be metabolized, radiolabeled chemicals, 14Cor3H, are often used. Dermatotoxicology Overview 205 In vivo studies have been conducted in humans and other species (12). Comparison of absorption rates of a number of compounds showed that absorp- tion rates in the rat and rabbit tend to be higher than humans and that the skin permeability of monkeys and swine more closely resembles that of humans. Guinea pig–human compari- sons offer some promise for refinement of guinea pig–human irritation and sensi- tization extrapolations (13). Although these differences are not predicted by any single factor, they are not unexpected in light of differences in metabolism and in routes of excretion. Therefore, the metabolic capabilities of the species should be considered when selecting an animal model and designing the experiment. Although there is no question that pharmacokinetic studies of this type in humans or animals provide the best estimate of percutaneous absorption, the cost and difficulty in conducting well-controlled studies have led to the use of other in vivo assays that are poorer predictive tools and to the development of in vitro models. In vitro assays using excised skin utilize specially designed diffusion cells (1,14,15). The skin is stretched over the opening of a collecting receptacle, epidermal side up. The chemical is applied to the epidermis and fluid from the receptacle is assayed to measure the penetration of the chemical. This type of in vitro assay offers some advantages over in vivo assays: highly toxic compounds can be studied in human skin, large numbers of cells can be run simultaneously, diffusion through the membrane (eliminating other pharmacokinetic factors) can be studied, and these assays may be easier to conduct. Comparison of penetration rates obtained from in vitro and in vivo assays have been made (1), often with a good correlation; however, with some, correla- tion was poor. Differences in the methods for some compounds could be ex- plained on the basis of solubilities in the receptacle fluid and blood; others could not be explained. Skin of the weanling pig and miniature swine appear to be good in vitro models for most compounds (2). Although a limited number of studies have been reported, the skin of monkeys also appears to be a good model (8). Rat skin appears to be a good model for some compounds; however, when differences have been noted, they have been large. By 1930, a procedure for producing this hypersensitivity to chemicals in guinea pigs had been developed (17). Landsteiner and associates demonstrated that low-molecular-weight chemicals conjugate with proteins to form an antigen that stimulates the immune system to form a hyperreactive state (18); immunogenicity is related to chemical structure (19); and two types of im- munological response exist, one transferable by serum and another transferred by suspensions of white blood cells (20). Appropriate planning and execution of predictive sensitization assays is critical. Choice of dose and vehicle appropriate to the assay and the study question is the second priority. Although dose must be high enough to ensure penetration, it must be below the threshold at challenge to avoid misinterpretation of irritant inflammation as allergic. Know- ing the irritation potential of compounds will allow the investigator to design and execute these studies appropriately. Vehicle choice determines in part the absorption of the test material and can influence sensitization rate, ability to elicit response at challenge, and the irritation threshold. A computer-assisted database describing the chemical structure and physico- chemical parameters of an array of chemicals provides a facile approach to de- signing appropriate in vitro, animal, and human sensitization studies (22).

The gravitational constant of the moon acne lotion effective 0.5 mg decadron, for example skin care jakarta timur cheap decadron 4 mg buy on-line, is one-sixth that of the Earth; therefore skin care 6 months before wedding decadron 1 mg order otc, the weight of a given object on the moon is one- sixth its weight on the Earth. It is a common mistake to assume that the height to which a person can jump on the moon increases in direct proportion to the decrease in weight. That is, if a person can jump to a height of 60 cm on Earth, that same person can jump up 6. Note that the ratio H /H 11 is true only for a particular choice of F in the calculation (see Exercise 3-2). The additional height is attained by using part of the kinetic energy of the run to raise the center of gravity off the ground. Let us calculate the height attainable in a running jump if the 1 2 jumper could use all his/her initial kinetic energy ( mv ) to raise his/her body 2 off the ground. If this energy were completely converted to potential energy by raising the center of gravity to a height H, then 1 2 MgH mv (3. Then we must remember that the center of gravity of a person is already about 1 m above the ground. With little extra effort, the jumper can alter the position of his body so that it is horizontal at its maximum height. Thus, our final estimate for the maximum height of the running high jump is v2 H + 1. Obviously, it is not possible for a jumper to convert all the kinetic energy of a full-speed run into potential energy. In the unaided running high jump, only the force exerted by the feet is available to alter the direction of the running start. The situation is quite different in pole vaulting, where, with the aid of the pole, the jumper can in fact use most of the kinetic energy to raise his/her center of gravity. These figures would agree even more closely had we included in our estimate the fact that the jumper must retain some forward velocity to carry him/her over the bar. A solution is required for the range R, the distance at which the projectile hits the Earth (see Fig. In other words a maximum range is obtained when the projectile is launched ata45◦ angle. In order to maximize the distance of the jump, the launching velocity and therefore also the resultant force should be directed at a 45◦ angle. We will assume as before that a jumper can generate with his feet a force equal to twice the body weight. The magnitude of the resultant force (Fr) and the angle θ at which the legs must apply the force to the body are obtained from the following considerations. W e will again assume that the force that launches the jumper is applied over a Section 3. The push-off force (2W) generated by the legs provides the vertical component of the launching velocity. The acceleration produced by the net force is 2W − W W a g m W/g If the push-off force acts on the jumper over a distance of 60 cm (the extent of the crouch) and if it is directed entirely in the vertical y direction, the vertical component of the velocity vy during the jump is given by 2 2 2 vy 2as 2 × g × 0. When an object moves through the air, the air molecules have to be pushed out of its way. The resulting reaction force pushes back on the body and retards its motion—this is the source of fluid friction in air. We can deduce some of the properties of air friction by sticking our hand outside a moving car. Clearly, the greater the velocity with respect to the air, the larger is the resistive force. By rotating our hand, we observe that the force is greater when the palms face the direction of motion. We therefore conclude that the resistive force increases with the velocity and the surface area in the direction of motion. Because of air resistance, there are two forces acting on a falling body: the downward force of gravity W and the upward force of air resistance. From Newton’s second law (see Appendix A), we find that the equation of motion in this case is W − Fa ma (3. If the body falls from a sufficiently great height, the velocity reaches a magnitude such that the force due to air resistance is equal to the weight.

Later acne wallet trusted decadron 8 mg, Goldberger showed that the shape of these recordings is not substantially altered by interrupting the connection between the central terminal and the site to be studied acne 5 year old 0.5 mg decadron order. The resulting leads augment the amplitude of the recording by 50% and are therefore called the augmented unipolar limb leads skin care for pregnancy buy cheap decadron 8 mg on-line. Vectocardiography considers the frontal, the sagittal and the transverse plane together. Six additional unipolar electrocardiographic leads -- the precordial leads -- provide information in the transverse plane. They use as reference the central terminal of Wilson and place the exploring electrode at six sites across the precordium. These precordial leads are called V1, V2, V3, V4, V5 and V6 as shown in Figure 11. By virtue of bringing the exploring electrode much closer to the heart the typical signals recorded from V1, V2, V3, V4, V5 and V6 cannot be correctly interpreted as projections of vectors on leads which are remote as compared to the size of the dipole. On the other hand, precordial leads provide more direct information about specific sites within the ventricle. Finally, it is important to keep in mind that there are simplifications inherent in this explanation of the electrocardiogram and its vectorial interpretation: 1. The importance of the electrocardiogram ultimately rests on its diagnostic value as an empirical tool to detect alterations in cardiac rhythm, in conduction pathways, in serum electrolytes and myocardial oxygenation. Blood vessels can be involved by all major categories of pathology, such as Congenital, Infective, Autoimmune, Neoplastic, Traumatic, Metabolic, and Toxic mechanisms. This lecture will present only a brief introduction to the broad range of vascular diseases, with a more thorough discussion of atherosclerosis. Noninfective: These are immune-mediated but they typically involve different types of patients, tissues and vessel sizes. The pathogenesis is poorly understood in most of these, and they will be discussed individually later in the course. Classification based on vessel size (with some typical features of presentation): 1. Small vessel: serum sickness, H-S purpura, cryoglobulinemia, drug-induced angiitis a. The stiffening is caused by hyperplasia of cells, increased extracellular matrix, deposition of proteins, or mineralization. In many forms of arteriosclerosis, the stiffening is due to a wound healing response to chronic Injury to the blood vessel wall. Often the stiffening is associated with stenosis of the vessel lumen, but aneurysm can also occur. Atherosclerosis: A type of arteriosclerosis involving larger arteries with lipid deposition and inflammation. Arteriosclerosis of vascular interventions: Intimal or medial thickening in response to angioplasty, stents, anastomosis, or autologous grafts. Graft arteriosclerosis: Due to immunologic injury to arteries in non-autologous organ transplants. Arteriolosclerosis: Sclerosis of small arteries and arterioles, usually due to hypertension or diabetes. Hyaline arteriolosclerosis due to deposition of plasma proteins and extracellular matrix in the wall (in elderly and hypertensives) b. Hyperplastic arteriolosclerosis (onion-skinning) due to smooth muscle hyperplasia ( in severe hypertension. It is a chronic disease that has a complicated multifactorial etiology with a variable presentation. Hyperlipidemia, inflammation, and thrombosis are key mechanisms in vascular injury and repair, which underlie atherosclerosis. There have been many efforts to establish other causative agents, including elevations of homocysteine, but the most important factors in atherosclerosis continue to be the “classic” ones: serum lipid levels, hypertension, diabetes, smoking, family history, age, and male sex. Vulnerable to injury from common agents like smoking, abnormal serum lipids, homocysteine levels, etc.

Hulda Regehr Clark began her studies in biology at the University of Saskatchewan, Canada, where she was awarded the Bachelor of Arts, Magna Cum Laude, and the Master of Arts, with High Honors. After two years of study at McGill University, she attended the University of Minnesota, studying biophysics and cell physiology. In 1979 she left government funded research and began private consulting on a full time basis. Clark puts her latest conclusions, her advice for curing cancer, her results and her methods before you. The translation here submitted to the public is the second translation of this work into English, it having before this been rendered by Dr. When it was proposed to reprint this translation, there was a strong protest made against the old version on the ground of its being to some degree inexact, and on account of its omitting not only the initials of the provers but besides this, also a great number of symptoms. These complaints have been proved well founded, especially with respect to the latter part of the work. We have taken a hundred symptoms at random here and there and compared them with the original, with the following results : in Alumina 555-655 we found only the omission of a part of symptom 556 and a partial omission and joining together of symptoms 617 and 618. So also in Graphites there is no omission except 53 (a repetition) in the first hundred, nor any other until we reach 200, 201 and 202 which are omitted. In the first hundred of Nitri acidum, however, we find 13 omissions, namely 6, 30, 32, 37, 38, 40, 43, 45, 59, 64, 65, 67 and 69. Between 1236 and 1335 there are 23 omissions, namely 1245, 1269, 1278, 1288, 1290, 1292, 1293, 1294, 1297, 1298, 1299, 1302, 1303, 1305, 1306, 1308, 1313, 1316, 1320, 1324, 1331, 1332, 1335, while one-half of the substance of symptoms 1287, 1296, 1312, 1315 and 1325 is omitted ; showing the omission in this extreme case of over one-fourth. The omissions are rather impartially distributed, about one-third of the above omissions being symptoms of Hahnemann, fully one-third, those due to Nenning and the other third, distributed impartially among the various other provers. These omissions made a new translation necessary, which was accordingly made independent of that of Dr. Hempel, though the earlier translation was consulted especially where there was any obscurity or ambiguity in the original. There is no question but that Hempel is right in what he says of the involved phraseology and the lengthy periods of Hahnemann ; still we did not think it best to follow his mode of rendering, which according to his preface consists in "mastering the sense of a period, and then embodying it in a free manner in the foreign tongue". Dudgeon in his admirable translation of the Materia Medica Pura (London, 1880) ; he has faithfully rendered not only the ideas but also the expressions of Hahnemann. We have accordingly preserved the long periods of Hahnemann and his own precise, if sometimes redundant, phraseology ; though, of course it was necessary to invert the periods and to arrange the phrases into the English order. This applies chiefly to the first theoretic part of the work, and in this part we would especially acknowledge the able assistance of Dr. Pemberton Dudley, who has taken care that too close a clinging to the German original might be avoided. We have generally endeavored to translate the same German word by the same English word, except where words have several meanings. Dudgeon with "pressive" or with "aching", we have uniformly rendered with pressive ; while we use "ache" to translate the German weh. There are a few words which require a varied translation according to the context : Brust is used both for "chest" and for "the female breast", so that e. We have taken care to translate these terms according to the context in every case, though the learned reader will remember that in some of these cases there is a little ambiguity. One of the German terms which seems to have no good English equivalent is Eingenommen with respect to the head. It means literally "occupied" and describes the sensation produced in the head by a cold, where the parts are as it were benumbed and incapacitated from acting freely. We have usually rendered it with "benumbed feeling", though as none of these terms was quite satisfactory, we have also sometimes used "muddled feeling" or "obtuseness". As was done in the Materia Medica Pura published in London, so we have also in this work printed the names of old school authorities cited with small capitals, while the names of other provers are in italics, so that it may be seen at a glance, whether the symptom was produced by an intentional proving (or from clinical experience), or whether it was the result of accidental poisoning or an overdose by an observer of the old school.
