That it has an important place in our therapeutics discount 2mg detrol otc treatment myasthenia gravis, we have no doubt detrol 4 mg generic treatment xanax overdose, but its exact place is not yet determined. Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 161 Dr. Jernigan experimented very extensively with crataegus and believes it is superior to many heart remedies when correctly prescribed. He believed it to have a broader field of action; no accumulative effect; no toxic influence; no contraindications, and acts in harmony with the other remedies. It has a general curative effect upon the functional action of the central nervous system; upon every part of the circulatory apparatus; upon the urinary organs, and the processes of metabolism. It dispels gloomy forebodings, increases the strength, regulates the action of the heart, causes a general sense of well being. In its mental influence he thinks he sees a resemblance to the action of pulsatilla, and very often prescribed the two remedies in conjunction. The doctor is sure he has seen excellent results from crataegus in the treatment of diabetes insipidus, especially in children, a difficult condition to control. He gave ten drops of the specific medicine every two hours for a while, controlling a form of epilepsy that showed itself with the other symptoms. He believes the remedy given for diabetes influences innervation, improving the circulation, especially in the capillaries when there were cold extremities. All of his cases confirmed his faith in the remedy as an important one for this condition. Sharp, of Ohio, says that he finds crataegus indicated in the usual diseases of the heart, and gives it in conjunction with the very best possible treatment to put the system into normal condition with proper diet and attention to the action of the skin, kidneys, and bowels. He reports three cases of serious heart disease in patients above 78 where the results were highly satisfactory. Stouffer, of Pennsylvania, suffered from a number of mild attacks of paralysis of the left side. The heart was directly influenced; oppression heavy; constriction of the throat; all symptoms increasing by exertion. He combined ceataegus and scutellaria, two parts of the former to one part of the latter, adding oil of peppermint, a few drops for the flavor. Of this he took a drop or two on his tongue very often, or as needed, obtaining relief, not secured by any other measure. Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 162 A greatly enlarged heart in a young man of sixteen with the symptoms usually present in older patients with precordial bulging was permanently benefited until a permanent cure seemed to be possible, by five drop doses of crataegus every three hours persisted in, over a period of several months. He had enlargement of the right side of the heart, the oppressed breathing at times being very severe. In a paroxysm, he took eight drops of crataegus every fifteen minutes with almost immediate relief. Young women, who from any cause suffer from mitral insufficiency, especially if rheumatism is present or the conditions that lead to it, may be cured by proper care and the use of five drop doses of crataegus three or four times a day. Therapy—Saffron tea was long in good repute among the grandmothers of our older men as an essential remedy to start new-born babes in normal health channels. It was thought necessary to encourage the action of the liver and to cleanse the intestinal canal and stomach. It may be given in the early stages of fevers, and especially in eruptive fevers, in full doses if there is a retrocession of the eruption. Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 163 It checks mild cases of irregular uterine hemorrhage, menorrhagia or metrorrhagia, and encourages the lochial discharge when suppressed after confinement. Therapy—The juice of the fruit is a diuretic with many individuals, producing a cooling sense of relief from heat or aching across the kidneys, or throughout the urinary apparatus. The seeds in the form of an infusion act promptly with children, relieving pain in the passage of urine and stimulating the flow of water. When male infants cry with every urination and the diaper is stained yellow, this remedy will correct the condition promptly. In those conditions accompanied with a general sense of constriction, or backache from the passage of urates and phosphatic gravel, this remedy exercises a direct soothing influence, not only upon the renal organs, but upon the bladder, especially when the irritation persists, warding off subsequent inflammation. A preparation of the fresh root should be employed, as it loses its properties by drying.
Important differences in isoforms produce significantly different contractile properties for skeletal muscle vs buy 4mg detrol overnight delivery symptoms you have diabetes. Smooth muscle exhibits even greater differences in organization and physiological properties effective 4 mg detrol treatment modalities, to be discussed in a later lecture. In skeletal and cardiac muscle, the thin filament proteins are actin, tropomyosin, and troponin (troponin T,C, or I). Each thin filament is attached to the Z-line material ( actinin) of the sarcomere. The heart of the thin filament is two strands of filamentous actin that coil about one another. The troponin- tropomyosin complex is associated with the thin filament and makes the sarcomere a calcium sensitive contractile structure. This complex regulates the interaction between the heads of the myosin molecule of the thick filament and the adjacent thin filament. The tropomyosin is envisaged as lying along the actin filament, blocking the myosin binding sites. Ca2+ binding to troponin C causes a conformational change in the rest of the troponin complex (I, C and T) and this in turn moves the tropomyosin aside and thereby activates the thin filament for contraction. There are some significant distinctions between thin-filament based regulation of Ca2+ sensitivity in cardiac and skeletal muscle. Cardiac TnC has one less functional Ca2+ binding site than skeletal TnC, making the Ca2+ regulation more graded. In the case of cardiac muscle, the input output relation of log [free Ca2+] vs tension rises steeply above 0. The Ca2+ sensitivity in heart can be regulated by TnI phosphorylation, which decreases the affinity of TnC for Ca2+, thereby increasing the rate of cardiac muscle relaxation. This relative newcomer to the field is proving interesting as a likely contributor to the elasticity of the muscle. The importance of elasticity will become clearer later in the course, when we discuss the mechanical properties of muscle. Titin is an enormous (3 mega-daltons), filamentous protein that spans half the length sarcomere and interacts with both the actin thin filament and myosin thick filament. It is thought to uncoil when the muscle is stretched, eventually acting to resist over-stretching of the sarcomere, keeping the muscle in its useful working range. On the other hand, when sarcomere length becomes very short, titin may help resist over compression and provide an elastic restoring force to quickly restore the sarcomere to resting length. Force Development Thick Filament Thick Filament Force S1 Thin Filament Thin Filament B. Shortening Thick Filament Thick Filament Thin Filament Thin Filament Displacement A. Huxley & Simmons 1971 model was very influential in thinking about the nature of the conformational change in myosin. It was a specific proposal for coupling chemical energy to molecular motion, involving a local conformational change, amplified by a lever arm, whereby metabolic reactions drove energy storage in the form of an extension of some kind of molecular spring (series elasticity). The existence of two myosin heads is thought to confer a 2-fold increase in Vmax for actin motion in motility assays. It is known that light chain phosphorylation occurs in a frequency-dependent manner, which might increase Ca2+ sensitivity. This is the rising and falling ability to support tension as muscle length progressively increases. The L-T relationship is a property of all striated muscle, and the key to the Frank-Starling Law of the Heart, as you will learn in Dr. In skeletal muscle, where it has been best studied, the various phases of the L-T relationship have been traced to variations in the ability of the crossbridges to exert productive force. However, there are some major differences between skeletal and cardiac muscle in the position of the rising phase of the L-T curve, the important phase for the Frank-Starling Law. The cardiac L-T curve is steeper, and operates over a very narrow range of lengths (dashed curve in diagram). This phase is supported by cardiac TnC but not skeletal TnC and has been found to depend in large part on changes in Ca2+ sensitivity of Ca2+ binding to cTnC V.
Dilutions generic 4 mg detrol visa medications side effects prescription drugs, properly so-called generic detrol 2 mg with visa treatment room, exist almost solely in objects of taste and of color. A solution of salty and bitter substances becomes continually more deprived of its taste the more water is added, and eventually it has hardly any taste, no matter how much it may be shaken. So, also, a solution of coloring matter, by the admixture of more and more water, becomes at last almost colorless, and any amount of shaking will not increase its color. These are, and continue to be, real attenuations or dilutions, but no dynamizations. Homœopathic Dynamizations are processes by which the medicinal properties, which are latent in natural substances while in their crude state, become aroused, and then become enabled to act in an almost spiritual manner on our life ; i. This development of the properties of crude natural substances (dynamization) takes place, as I have before taught, in the case of dry substances by means of trituration in a mortar, but in the case of fluid substances, by means of shaking or succussion, which is also a trituration. These preparations cannot be simply designated as dilutions, although every preparation of this kind, in order that it may be raised to a higher potency ; i. We frequently read in homœopathic books that, in the case of one or another person in a certain case of disease, some high (dilution) dynamization of a medicine was of no use at all, but a lower potency proved effectual, while others have seen more success from higher potencies. But no one in such cases investigates the cause of the great indifference of these effects. What prevents the preparer of the medicines (and this ought to be the homœopathic physician himself ; he himself ought to forge and whet the arms with which to fight the diseases) -what prevents him, in preparing a potency, from giving 10, 20, 50 and more succussive strokes against a somewhat hard, elastic body to every vial containing one drop of the lower potency with 99 drops of alcohol, so as to obtain strong potencies? This would be vastly more effective than giving only a few nerveless succussive strokes, which will produce little more than dilutions, which ought not to be the case. The perfection of our unique art of healing and the welfare of the patients seem to make it worth while for the physician to take the trouble necessary to secure the utmost efficiency in his medicines. Modern wiseacres have even sneered at the 30th potency, and would only use the lower, less developed and more massive preparations in larger doses, whereby they have been, however, unable to effect all that our art can accomplish. If, however, every potency is dynamized with the same number of succussive strokes, we obtain, even in the fiftieth potency, medicines of the most penetrating efficacy, so that every minute pellet moistened with it, after being dissolved in a quantity of water, can and must be taken in small parts, if we do not wish to produce too violent an action with sensitive patients, while we must remember that such a preparation contains almost all the properties latent in the drug now fully developed, and these can only then come into full activity. Since I last [*] addressed the public concerning our healing art, I have had among other things also the opportunity to gain experience as to the best possible mode of administering the doses of the medicines to the patients, and I herewith communicate what I have found best in this respect. A small pellet of one of the highest dynamizations of a medicine laid dry upon the tongue, or the moderate smelling of an opened vial wherein one or more such pellets are contained, proves itself the smallest and weakest dose with the shortest period of duration in its effects. Still there are numerous patients of so excitable a nature, that they are sufficiently affected by such a dose in slight acute ailments to be cured by it if the remedy is homœopathically selected. Nevertheless the incredible variety among patients as to their irritability, their age, their spiritual and bodily development, their vital power and especially as to the nature of their disease, necessitates a great variety in their treatment, and also in the administration to them of the doses of medicines. For their diseases may be of various kinds : either a natural and simple one but lately arisen, or it may be a natural and simple one but an old case, or it may be a complicated one (a combination of several miasmata), or again what is the most frequent and worst case, it may have been spoiled by a perverse medical treatment, and loaded down with medicinal diseases. I can here limit myself only to this latter case, as the other cases cannot be arranged in tabular form for the weak and negligent, but must be left to the accuracy, the industry and the intelligence of able men, who are masters of their art. Experience has shown me, as it has no doubt also shown to most of my followers, that it is most useful in diseases of any magnitude (no excepting even the most acute, and still more so in the half-acute, in the tedious and most tedious) to give to the patient the powerful homœopathic pellet or pellets only in solution, and this solution in divided doses. In this way we give the medicine, dissolved in seven to twenty tablespoonfuls of water without any addition, in acute and very acute diseases every six, four or two hours ; where the danger is urgent, even every hour or every half-hour, a tablespoonful at a time ; with weak persons or children, only a small part of a tablespoonful (one or two teaspoonfuls or coffeespoonfuls) may be given as a dose. But since water (even distilled water) commences after a few days to be spoil, whereby the power of the small quantity of medicine contained is destroyed, the addition of a little alcohol is necessary, or where this is not practicable, or if the patient cannot bear it, I add a few small pieces of hard charcoal to the watery solution. This answers the purpose, except that in the latter case the fluid in a few days receives a blackish tint. This is caused by shaking the liquid, as is necessary every time before giving a dose of medicine, as may be seen below. Before proceeding, it is important to observe, that our vital principle cannot well bear that the same unchanged dose of medicine be given even twice in succession, much less more frequently to a patient. For by this the good effect of the former dose of medicine is either neutralized in part, or new symptoms proper to the medicine, symptoms which have not before been present in the disease, appear, impeding the cure. Thus even a well selected homœopathic medicine produces ill effects and attains its purpose imperfectly or not at all. Thence come the many contradictions of homœopathic physicians with respect to the repetition of doses. But in taking one and the same medicine repeatedly (which is indispensable to secure the cure of a serious, chronic disease), if the dose is in every case varied and modified only a little in its degree of dynamization, then the vital force of the patient will calmly, and as it were willingly receive the same medicine even at brief intervals very many times in succession with the best results, every time increasing the well-being of the patient. This slight change in the degree of dynamization is even effected, if the bottle which contains the solution of one or more pellets is merely well shaken five or six times, every time before taking it. Now when the physician has in this way used up the solution of the medicine that had been prepared, if the medicine continues useful, he will take one or two pellets of the same medicine in a lower potency (e.
Therefore adjustment of vessel dilatation and constriction would always accommodate to tissue oxygen needs buy 1 mg detrol otc treatment jokes. In the case of fixed stenoses of coronary vessels with myocardial Angina Pectoris - James Topper detrol 4mg line treatment trends, M. Recently it has been shown by arteriography, as well as indirect measurements of coronary vascular resistance, that there is a great deal of spontaneous oscillation in coronary tone in both normal and diseased vessels, and vasoconstriction may play an important and frequent role in the development of angina. Furthermore, such vasoconstriction had, for a long time, been assumed to be related to autonomic innervation of the vessels. Although some tonic or physiologic role may be present, it is known that other mediators (i. As a final note, transplanted hearts can demonstrate intense coronary spasm despite a complete lack of innervation. This is known as the "double product" and can be used as an indirect index of changing myocardial oxygen demand in a given individual. The standard treadmill exercise test uses this to determine the endpoint of exercise or to compare the effect of drugs on exercise tolerance. Sonnenblick emphasized the importance of velocity of contraction of muscle as a determinant of oxygen demand. Coronary sinus lactate concentrations increase and may exceed circulating systemic arterial levels. Hemodynamic: Pain itself may produce autonomic discharge leading to change in heart rate. For reasons not completely understood, inferior (diaphragmatic) ischemia may produce sinus bradycardia or even atrioventricular conduction disturbances (which typically respond to atropine, a drug which antagonizes the action of the vagal neurotransmitter, acetylcholine. Ischemia of a large segment of myocardium produces stiffness or decreased compliance, leading to a rise in end-diastolic pressure and favoring the development of an S-4 (atrial) gallop sound, as well as transient pulmonary congestion (Sometimes dyspnea may be the only sign of temporary ischemia: "painless angina"). Ischemia also causes a temporary loss of contractility, which, if severe, will lead to a fall of ejection fraction (E. This, too, will favor pulmonary congestion and the development of a gallop (S#3 or S4) sound. Electrophysiologic: The left ventricular subendocardium is the most vulnerable to ischemia. The ischemic myocardium, perhaps because of its inability to maintain transmembrane ionic gradients, has a lower voltage during the plateau (phase 2). This finding is used to diagnose ischemia during stress (treadmill exercise) tests. Myocardial perfusion pressure: (coronary arterial pressure minus left ventricular pressure) a. Decreased aortic diastolic pressure (shock, aortic insufficiency) Angina Pectoris - James Topper, M. Obviously, common disorders may embarrass cardiac function because of simultaneous operation of several mechanisms: 1. Abrupt changes in demand are almost always due to the autonomic nervous system control of heart rate, contractility and blood pressure in response to excitement or activity. The patient usually realizes very early in his disease to discontinue the physical or emotional stimulus of chest pain. If the attack occurs during an examination, then the physician can stimulate the carotid sinus and provoke reflex vagal discharge and a decrease in sympathetic tone. The use of a drug which blocks the action of norepinephrine on heart rate and contractility can provide a pharmacologic decrease in sympathetic tone. Severe anemia or arterial hypoxemia are relatively rare causes of angina in the industrialized counties. Transfusion of red cells or administration of oxygen (in ambient air) will be sufficient therapy in these cases. The incidence and importance of coronary artery spasm as the cause of angina is not known.
