D Beer’s law states that A = a × b × c, where a is the Beer’s law/1 absorptivity coefficient (a constant), b is the path 4. A A solution transmits light corresponding in Spectrophotometry/2 wavelength to its color, and usually absorbs light of wavelengths complementary to its color. A green-colored solution would show highest red solution transmits light of 600–650 nm and transmittance at: strongly absorbs 400–500 nm light. A solution that is green would be quantitated using a wavelength that it absorbs strongly, such as 450 nm.

Output 100%T control at maximum, the instrument increases as wavelength becomes longer peaking readout will not rise above 90%T. Insert a wider cuvette into the light path becomes insufficient to set the blank reading to C. A sharp cutoff filter and a variable exit slit generate a continuous spectrum of fairly uniform C. Interference filters and a variable exit slit intensity from 300–2,000 nm, making them useful D. A diffraction in order to measure the true absorbance of a grating produces a uniform separation of compound having a natural absorption wavelengths.

An acute shift toward anabolism may unmask preexisting body electrolyte deficiencies (see Monitoring Progress and Complications discount lamisil 250mg otc fungus yellow nails, below generic 250 mg lamisil visa fungus under toenail. Abnormalities of acid–base balance also occur more frequently in such patients lamisil 250 mg with amex fungus on tongue, and alterations in electrolyte compo- sition (such as acetate salts) of solutions may be indicated order lamisil 250mg amex antifungal for mouth. As always, patients with indwelling catheters must be monitored carefully for 58 S. An abrupt change in glucose tolerance may indicate infection related to the catheter or another source. Problems Related to Access These problems can be life-threatening and include misadventures related to placement of enteral or parenteral feeding portals. Acute pneumothorax, inadvertent arterial puncture, air embolism, and per- foration of the vena cava or heart can accompany attempts at central venous access. Insertion of catheters by experienced personnel serves to minimize these complications. More frequently, however, it is the initial misplacement of the catheter or latent events such as insertion-site infection or vessel thrombosis that provide troubling morbidities to patients. These complications are monitored by a rigorous adherence to sterility guidelines and protocols and by regular physical examination of the patient. A constant awareness of the potential for these events promotes early intervention and treatment. Problems related to placement of enteral feeding portals arise with similar, if not greater, frequency. Although it is increasingly popular to return to intragastric feeding, proper tube placement and function also must be assured. Problems of aspiration, especially in patients prone to reflux, may preclude this route of enteral nutrient provision. Under such circumstances, the placement of small-bore feeding catheters either transgastrically or transcutaneously requires experienced per- sonnel. As noted above, enteral feeding tubes may cause abdominal distention or symptoms that must be investigated. Careful, daily physical examination is an essential component of the monitoring regimen. Problems related to access portals as well as organ dys- function and fluid imbalance may be detected initially, or solely, on this basis. A determination of red blood cell indices may help to define iron deficiency (not routinely provided in intravenous nutrition). Eval- uation of basic bleeding parameters is undertaken to detect the pres- ence of vitamin K deficiency, which also may develop in parenterally fed patients. Trace mineral deficiencies may be a latent problem, especially in patients with preexisting malnutrition and prolonged inflammatory conditions. Attention should be given to patients with previous compromise of intestinal absorption. Problems of Excess Significant changes in overall clinical status as well as specific organs may provoke a state of excess provision. At least daily evalua- tion of glucose tolerance, by blood or urine sampling, is indicated in all patients. An abrupt increase in glucose levels in an otherwise stable patient must suggest infection until proven otherwise. Glucose excess also may precipitate or aggravate pulmonary prob- lems in some patients. If the rate of endogenous glucose oxidation is exceeded, carbon dioxide retention may result in respiratory distress or weaning problems in ventilated patients. Other evidence of nutrient excess occurs during conditions of evolv- ing organ dysfunction. A reduction in volume and nitrogen load as well as evaluation of electrolyte tolerance may be indicated. Under such circumstances, a reduction in nitrogen load or alteration in amino acid formulation may be indicated. Some patients may require liquid diets as a transition to solid food, but this does not necessitate an interruption of the tapering schedule. In patients who have been receiving supplemental insulin, peripheral low-dose dex- trose infusions minimize the chances of hypoglycemia. This decision requires input from several sources, including family and home healthcare agencies as well as social work and nursing professionals.

To recognize the clinical manifestation of common electrolyte abnormalities and methods for their correction. Case 2 A 40-year-old woman presents with a 1 week history of persistent upper abdominal pain in association with nausea and vomiting. Physical examination is unrevealing except for loss of skin turgor and reduced breath sounds over the right chest. Case 3 A 58-year-old woman presents with a 1-week history of confusion, lethargy, and persistent nausea. Introduction An understanding of changes in fluid, electrolyte, and acid–base con- cepts is fundamental to the care of surgical patients. These changes can range from mild, readily correctable deviations to life-threatening abnormalities that demand immediate attention. This chapter outlines some of the physiologic mechanisms that initiate such imbalances and methods to systematically evaluate the diverse clinical and biochemi- cal data that lead to decisions regarding therapy. The information and data presented below are intended for application in adult patients, although the principles espoused also are germane to pediatric patients. Basic Concepts The Stress Response The normal physiologic response to injury or operation produces a neuroendocrine response that preserves cellular function and pro- motes maintenance of circulating volume. This is readily demon- strable in terms of retention of water and sodium and the excretion of potassium. Many stimuli can produce this response, including many associated with trauma or operation. Aldosterone also is increased by elevated levels of potassium, a common consequence of tissue injury. Hydrocortisone and catecholamine release also contribute to the excretion of potassium. The exogenous administration of electrolytes results in the distribution of that ion to the usual fluid com- partment of highest preferential concentration. Electrolytes When an electrolyte dissolves in water, it releases positive and nega- tive ions.

Emma: Filled with anxiety Emma lamisil 250mg amex fungus gnats potato, a 37-year-old loan officer cheap 250 mg lamisil with visa fungus yogurt, regularly puts in a 50-hour workweek cheap lamisil 250mg visa antifungal medication. She worries about keeping up with her job and being a good mother to her two children cheap 250mg lamisil free shipping fungus killing bananas. So when Emma’s son brings home a mediocre report card, she crashes into a terrible depres- sion. She loses her temper and screams at her son, and then she berates herself for being a terrible mother. Emma completes a Thought Tracker and then puts her most malicious thought on trial (see Worksheet 6-10). Worksheet 6-10 Emma’s Thought on Trial Worksheet Accused thought: I’m a complete failure as a mother; my son is falling apart. Defending the Thought Prosecuting the Thought My son is doing horrible in He had one bad report card. If I were a good mother, I I wonder why the teacher didn’t contact me would have known that he before report card time. I haven’t gone on a field trip Out of 30 kids, only a few parents were able to with my son’s class because drive on field trips. Other mothers even I wish I could spend more time with my son, but volunteer in the classroom. I have been putting my job That’s not really true; when my kids really need ahead of my children. Chapter 6: Indicting and Rehabilitating Thoughts 87 Defending the Thought Prosecuting the Thought I don’t know what to do to I guess I’ll do what the teacher suggests and help him. Thought Court is one of the most effective tools for combating anxiety, depression, and other unpleasant emotions. If you have trouble with the exercise, spend more time going over the Prosecutor’s Investigative Questions in Worksheet 6-3. It also doesn’t hurt to review Chapter 5 and re-read the examples in this chapter. If you still struggle, we recom- mend you consult a mental health professional who’s proficient in cognitive therapy. After the Verdict: Replacing and Rehabilitating Your Thoughts Hopefully, the prosecution presents a convincing case against a variety of your malicious thoughts, and you begin to see that many of your thoughts are guilty of scrambling reality and causing excessive emotional distress. When criminals are convicted, society usually tries to rehabilitate them and give them a second chance. In this section, we show you how to rehabilitate your guilty thoughts, one at a time. Rehabilitating your thoughts decreases feelings of depression and anxiety because rehabili- tated thoughts are less distorted, judgmental, and critical. We call rehabilitated thoughts replacement thoughts because they replace your old malicious thoughts. The reason for forming a single replacement thought is that you can use that new thought repeatedly when- ever the old, malicious thoughts start rumbling through your mind. The new thought is a quick and easy comeback to negative, distorted, reality-scrambled thinking. You can use a number of different techniques to develop effective replacement thoughts. The strategies outlined in the following sections help you discard distortions and straighten out your thinking. With these strategies, you discover how to replace your twisted thoughts with more helpful, realistic replacement thoughts. You start by imagining that a good friend of yours is going through the same kind of problem as you are. We don’t want you to simply try to make your friend feel better by sugarcoating the issue; rather, tell your friend about a reasonable way to think about the problem. The essence of this powerful, yet surprisingly simple, technique is that the advice you would give a friend is advice you can give to yourself. The following example shows you how to use Getting Help from a Friend to your advantage. Emma (see “Emma: Filled with anxiety” earlier in this chapter) has taken her most malicious thought to Thought Court and found it guilty. She imagines Louise coming to her with the same problem and concerns about her son. In other words, Louise is thinking Emma’s most malicious thought and seeking advice (see Worksheet 6-11). Emma’s/Louise’s most malicious thought: I’m a complete failure as a mother; my son is falling apart. Worksheet 6-11 Emma’s Getting Help from a Friend (Louise) Well, Louise, I know you feel like a failure, but your son only came home with two C’s and three B’s. Sure, you haven’t spent as much time with him lately, but you’ve been pretty tied up at work. Besides, your son is 16 now; don’t you think he has something to do with his own success and failure? She sees that her perspective changes when she gives Louise advice rather than listen to the negative automatic dialogue in her own head. Next, she distills this perspective into a single replacement thought (see Worksheet 6-12). Worksheet 6-12 Emma’s Replacement Thought My son isn’t falling apart and I’m not a failure. Chapter 6: Indicting and Rehabilitating Thoughts 89 Take one of your most malicious thoughts and use the Getting Help from a Friend strategy to devise an effective response to that thought. Of course, it helps to take the malicious thought to Thought Court first, which you’ve done — right? Write down one of your most malicious thoughts from your Thought Tracker (see Worksheet 6-6). Imagine that the friend has a problem very similar to your own and has similar thoughts about the problem. Imagine you’re talking with your friend about a better way to think about and deal with the problem. Look over that advice and try to rehabilitate your most malicious thought into a more balanced, summary replacement thought in Worksheet 6-14. My most malicious thought: __________________________________________________________________________________ Worksheet 6-13 My Getting Help from a Friend Worksheet 6-14 My Replacement Thought Traveling to the future The events that disrupt your life today rarely have the same meaning after a few days, weeks, or months. If you think back on these events after some time has passed, however, rarely can you muster up the same intensity of emotion. That’s because most upsetting events truly aren’t all that important if you look at them in the context of your entire life. Check out the following example of the Traveling to the Future technique in action. He’d like to sell the property, but he knows it’s worth far more if it can be zoned for commercial purposes first. In order to do that, Joel must present his case in front of the Zoning Commission. He expects some opposition and criticism from homeowners in the area, and he’s been putting this task off for months because of the intense anxiety it arouses in him.

Staining of bacteria Bacterial staining is the process of coloring of colorless bacterial structural components using stains (dyes) lamisil 250 mg overnight delivery fungus vs virus. The principle of staining is to identify microorganisms selectively by using dyes purchase lamisil 250 mg visa fungus gnats kill plants, fluorescence and radioisotope emission lamisil 250mg sale fungus soap. Staining reactions are made possible because of the physical phenomena of capillary osmosis purchase lamisil 250mg mastercard fungus in hair, solubility, adsorption, and absorption of stains or dyes by cells of microorganisms. Individual variation in the cell wall constituents among different groups of bacteria will consequently produce variations in colors during microscopic examination. Whereas, cytoplasm is basic in character and has greater affinity for acidic dyes. Because dyes absorb radiation energy in visible region of electromagnetic spectrum i. Direct staining Is the process by which microorganisms are stained with simple dyes. A mordant is the substance which, when taken up by the microbial cells helps make dye in return, serving as a link or bridge to make the staining recline possible. It combines with a dye to form a colored “lake”, which in turn combines with the microbial cell to form a “ cell-mordant-dye- complex”. It is an integral part of the staining reaction itself, without which no staining could possibly occur. A mordant may be applied before the stain or it may be included as part of the staining technique, or it may be added to the dye solution itself. An accentuator, on the other hand is not essential to the chemical union of the microbial cells and the dye. It does not participate in the staining reaction, but merely accelerate or hasten the speed of the 26 staining reaction by increasing the staining power and selectivity of the dye. Progressive staining - is the process whereby microbial cells are stained in a definite sequence, in order that a satisfactory differential coloration of the cell may be achieved at the end of the correct time with the staining solution. Regressive staining - with this technique, the microbial cell is first over stained to obliteratethe cellulare desires, and the excess stain is removed or decolorized from unwanted part. Differentiation (decolorization) - is the selective removal of excess stain from the tissue from microbial cells during regressive staining in order that a specific substance may be stained differentiallyh from the surrounding cell. Differentiation is usually controlled visually by examination under the microscope Uses 1. Basic stains are stains in which the coloring substance is contained in the base part of the stain. Acidic stains are stains in which the coloring substance is contained in the acidic part of the stain. Eosin stain Neutral stains are stains in which the acidic and basic components of stain are colored. Simple staining method It is type of staining method in which only a single dye is used. Usually used to demonstrate bacterial morphology and arrengement Two kinds of simple stains 1. Apply a few drops of positive simple stain like 1% methylene blue, 1% carbolfuchsin or 1% gentian violet for 1 minute. Negative staining: The dye stains the background and the bacteria remain unstained. Differential staining method Multiple stains are used in differential staining method to distinguish different cell structures and/or cell types. Most bacteria are differentiated by their gram reaction due to differences in their cell wall structure. Gram-positive bacteria are bacteria that stain purple with crystal violet after decolorizing with acetone-alcohol. Gram-negative bacteria are bacteria that stain pink with the counter stain (safranin) after losing the primary stain (crystal violet) when treated with acetone-alcohol. Cover the fixed smear with crystal violet for 1 minute and wash with distilled water. Ziehl-Neelson staining method Developed by Paul Ehrlichin1882, and modified by Ziehl and Neelson Ziehl-Neelson stain (Acid-fast stain) is used for staining Mycobacteria which are hardly stained by gram staining method. Once the Mycobacteria is stained with primary stain it can not be decolorized with acid, so named as acid-fast bacteria. Prepare the smear from the primary specimen and fix it by passing through the flame and label clearly 2. Place fixed slide on a staining rack and cover each slide with concentrated carbol fuchsin solution. Heat the slide from underneath with sprit lamp until vapor rises (do not boil it) and wait for 3-5 minutes. Cover the smear with 3% acid-alcohol solution until all color is removed (two minutes). Cover the smear with 5% malachite green solution and heat over steaming water bath for 2-3 minutes. Cover the smear with 1% aqueous crystal violet for 1 minute over steaming water bath. Water Peptone: Hydrolyzed product of animal and plant proteins: Free amino acids, peptides and proteoses(large sized peptides). It provides nitrogen; as well carbohydrates, nucleic acid fractions, minerals and vitamins. Other elements Carbohydrates: Simple and complex sugars are a source of carbon and energy. Water Deionized or distilled water must be used in the preparation of culture media. Basic /Simple / All purpose media It is a media that supports the growth of micro-organisms that do not require special nutrients. To subcuture pathogenic bacteria from selective/differential medium prior to performing biochemical or serological tests. Enriched media Media that are enriched with whole blood, lyzed blood, serum, special extracts or vitamins to support the growth of pathogenic bacteria. Enrichment media Fluid media that increases the numbers of a pathogen by containing enrichments and/or substances that discourage the multiplication of unwanted bacteria. Antibiotics) that prevent or slow down the growth of bacteria other than pathogens for which the media are intended. Differential media Media to which indicator substances are added to differentiate bacteria. Transport media Media containing ingredients to prevent the overgrowth of commensals and ensure the survival of pathogenic bacteria when specimens can not be cultured soon after collection. Amies transport media Stuart media Kelly-Blair media Choice of culture media The selection culture media will depend on: 1. The major pathogens to be isolated, their growth requirements and the features by which they are recognized. Whether the specimens being cultured are from sterile sites or from sites having normal microbial flora. The training and experience of laboratory staff in preparing, using and controlling culture media. Fluid culture media Bacterial growth in fluid media is shown by a turbidity in the medium. The major processes during preparation of culture media • Weighing and dissolving of culture media ingredients • Sterilization and sterility testing • Addition of heat-sensitive ingredients • Dispensing of culture media • pH testing of culture media • Quality assurance of culture media • Storage of culture media 1. Weighing and dissolving of culture media ingredients Apply the following while weighing and dissolving of culture media ingredients • Use ingredients suitable for microbiological use. Sterilization and sterility testing Always sterilize a medium at the correct temperature and for the correct length of time as instructed in the method of preparation. Filtration A) Autoclaving Autoclaving is used to sterilize most agar and fluid culture media.

Nursing Considerations: Carbamazepine (Tegretol), Phenobarbitol, Phenytoin (Dilantin) all anticonvulsants, may lower Klonopin (anticonvulsant) level. Usual maintenance dosage is 5 to 15 mg/kg orally daily (maximum 400 mg daily in two divided doses. Children older than 12 and adults start at 50 mg orally daily for 2 weeks; then 100 mg orally daily in two divided doses for two weeks. Available forms are: tablets 25 mg, 100 mg, 150 mg, and 200 mg; tablets (chewable dispersible) 2 mg, 5 mg and 25 mg. Nursing Considerations: Acetaminophen (Tylenol) may decrease therapeutic effects of Lamictal (anticonvulsant). If tablets are chewed, give a small amount of water or diluted fruit juice to aid in swallowing. Combination therapy of Depakote (anticonvulsant) and Lamictal (both anticonvulsants) may cause a serious rash. Tell patient to report rash or signs and symptoms of hypersensitivity promptly because they may warrant stopping drug. Children over age 8 and adults, initially 100 mg to 125 mg orally at bedtime on days 1 to 3, then 100 mg to 125 mg orally twice a day on days 4 to 6; then 100 mg to 125 mg orally three times a day on days 7 to 9, followed by maintenance dose of 250 mg orally three times a day. Nursing Considerations: Acetazolamide (Diamox – diuretic), Succinimide (anticonvulsant) may decrease Mysoline (anticonvulsant) level. Therapeutic level of Phenobarbital (anticonvulsant) is 15 to 40 mcg/ml (both anticonvulsants). Available forms are: capsules in 100 mg, 300 mg, and 400 mg; oral solution 250 mg/5 ml; tablets in 100 mg, 300 mg, 400 mg, 600 mg and 800 mg. Nursing Considerations: Antacids may decrease absorption of Neurontin (anticonvulsant). Seizures and delirium may occur within 16 hours and last up to 5 days after abruptly stopping drug. Children ages 6 to 12, initially 100 mg orally twice a day (conventional or extended release tablets) or 50 mg of suspension orally four times a day with meals, increased at 88 weekly intervals by up to 100 mg oral divided in three or four doses daily (divided twice a day for extended release form). Usual maintenance dosage is 400 mg to 800 mg daily or 20 mg/kg to 30 mg/kg in divided doses three or four times daily. Children older than 12 and adults, initially 200 mg orally twice a day (conventional or extended release tablets), or 100 mg orally four times a day of suspension with meals.

The peak time for tablets is 1½ hours to 12 hours and the peak time for tablets (extended release) is 4 to 8 hours. Nursing Consideration: Atracurium, Cisatracurium, Pancuronium, Rocuronium, Vecuronium (all blocking agents), may decrease the effects of nondepolarizing muscle relaxant, causing it to be less effective. Capsules and tablets should not be crushed or chewed, unless labeled as chewable form. Do not confuse Carbatrol (anticonvulsant) with Carvedilol (Coreg – antihypertensive). Tell patient taking suspension form to shake container well before measuring dose. Advise him to avoid hazardous activities until effects disappear, usually within 3 or 4 days. Nursing Considerations: Contraindications are those with a hypersensitivity to Benzodiazepines, Acute Angle Closure Glaucoma, Psychosis, concurrent Ketoconazole (Nizoral - antifungal) or Itraconazole (Sporonox - antifungal) therapy, and children younger than age 9. Instruct patient to avoid driving and other hazardous activities until he knows how drug affects concentration and alertness. Increase at 1 or 2 week intervals by 1 mg/kg to 3 mg/kg daily in two divided doses to achieve optimal response. Children over age 10 and adults, initially 25 mg to 50 mg orally daily, increase gradually by 25 mg to 50 mg weekly until an effective daily dose is reached. Adjust to recommended daily dose of 200 mg to 400 mg orally in two divided doses for those with partial seizures or 400 mg orally in two divided doses for those with primary generalized tonic clonic seizures. Available forms are: capsules, sprinkles in 15 mg and 25 mg; tablets 25 mg, 50 mg, 100 mg, and 200 mg. Nursing Considerations: Tegretol (anticonvulsant) may decrease Topamax (anticonvulsant) level. May decrease Bicarbonate (buffer system in acid-base system) and hemoglobin levels and 97 hemacrit. Factors that may predispose patients to acidosis, such as renal disease, severe respiratory disorders, status epilepticus, diarrhea, surgery, ketogenic diet, or drugs, may add to Topamax’s (anticonvulsant) bicarbonate lowering effects. If metabolic acidosis develops and persists, consider reducing the dose, gradually stopping the drug, or alkali treatment. The target maintenance dose depends on patient’s weight and should be divided twice a day. If patient weights between 20 kg and 29 kg (44 and 64 pounds), target maintenance dose is 900 mg daily. If patient weighs between 29 and 39 kg (64 and 86 100 pounds), target maintenance dose is 1200 mg daily. If patient weighs more than 39 kg (86 pounds), target maintenance dose is 1800 mg daily. Increase by a maximum of 600 mg daily (300 mg orally twice a day) at weekly intervals.

Howe uses it in combination with Veratrum purchase lamisil 250mg without prescription antifungal bath soap, and there is no doubt that this renders the system tolerant of Arsenic where it could not otherwise be employed generic lamisil 250 mg overnight delivery fungus mega brutal. The majority of the “cancer specialists” use it in some form buy lamisil 250 mg without prescription antifungal research, and their preparations differ only in the inert material with which it is combined cheap 250 mg lamisil overnight delivery vacuum fungus gnats. The preparation now employed most frequently is made as follows: Take Hydrated Sesquioxide of Iron a sufficient quantity, throw it on a paper filter, and when of the consistence of an ointment, add an equal part of Lard. Arsenic may be employed in the treatment of some cases of intermittent fever with excellent results. They are those marked by impairment of sympathetic innervation, and with a general want of nervous excitability. I have used the Homœopathic pellets, medicated with Fowler’s Solution, and though the dose was not more than the twentieth to the one-hundredth of a drop, the effect was marked, where specially indicated. It is also used with advantage in atonic diarrhœa, with indigestion, the conditions being as above named. Especial benefit has been observed in those cases in which there were periods of great depression, followed by hectic fever. I need hardly say in conclusion, that Arsenic is one of those agents that will do either good or harm. Good if given in a proper case, and in medicinal doses; harm if not indicated by special symptoms, or contra-indicated as above named, or if given in poisonous doses. It is indicated by hoarseness and loss of voice, with burning and constriction of the throat, sneezing, and thin ichorous discharge from the nose. Our Homœopathic friends say that a “keynote” for this remedy is “children pick the nose and chin persistently. This agent has been used principally as a vermifuge, but lately it has given place to the Chenopodium and to Santonine. It possesses very decided medicinal properties, however, and deserves a thorough examination. Its principal use has been as a vermifuge in cases of ascaris lumbricoides, for which it has been found quite efficient. But in using it for this purpose many have noticed that it exerted a peculiar influence upon the brain, and upon the eyes - rendering objects blue, yellow, or green; and that it passed off in the urine, giving it a peculiar color. It exerts a specific action upon the bladder and urethra, stimulating contraction of the first, and allaying irritation of the second. It is especially valuable in cases of retention of urine in children during protracted disease: in doses of half to one grain, it is prompt and certain. I judge it to be a nerve stimulant, and have employed it for this purpose to a limited extent. An infusion of twelve to twenty honey bees in a pint of boiling water, is one of the most certain diuretics I have ever employed in cases of suppression of urine from atony. It is also a very efficient remedy in retention of urine, and in some cases of irritation of the urethra. I have used the tincture for the same purpose, and also for inflammation of subcutaneous structures, with tensive and lancinating pains, and in irritation of the skin. I have seen a number of cases of disease in women characterized by sensations of heat, and burning pains in the bladder and course of the urethra, with frequent desire to micturate. These have been promptly relieved by the use of tincture Apis, and in two cases of chronic disease of long standing, a permanent cure was effected, following the relief of these unpleasant symptoms. It is claimed by those who have made considerable use of them, that they stimulate all the secretions. Whilst I think but little of this fœtid gum as an anti-spasmodic, I regard it as a valuable gastric stimulant, and also as a nerve stimulant. When given freely, it is one of the most certain diaphoretics we have, providing the pulse is not frequent, and the temperature increased. Even in the small dose of one drop, following the use of the special sedatives, it will markedly increase the true secretion from the skin. There may be a profuse exudation of water, the surface being bathed in perspiration, and yet but little secretion. Excretion by the skin is a vital process, and takes place by means of secreting cells. It goes on best where the skin is soft and moist, and not when covered with drops of sweat. I employ Asclepias in diseases of children, believing that it allays nervous irritability, is slightly sedative, and certainly increases the secretion from the skin. Of this the maximum dose will be one drop, but frequently one-fifth to one-half of this will serve a better purpose. For hypodermic use, we employ a solution of Atropia, in the proportion of one grain to the ounce of distilled water. The specific use of Belladonna is as a stimulant to the capillary circulation, especially of the nerve centers - a remedy opposed to congestion. My attention was first drawn to it by an article from Brown-Sequard, giving the results of his experiments with the drug, stating that with the microscope he had seen marked contraction of the capillaries following its use. It at once suggested itself to me, that if it would cause capillary contraction, it would be the remedy for congestion; and I at once commenced experimenting with it in this direction. I well recall my first marked case: a boy about eight years old, suffering from malignant rubeola. The administration of Belladonna alone (in small doses) was sufficient to restore consciousness, and a free circulation, with good appearance of the eruption, in twenty hours. The evidences in its favor rapidly accumulated, so that in eighteen months I used it with a feeling of almost certainty for this purpose. Whilst it exerts the same influence on all persons, and at all ages, the true pathological condition being determined, it is especially valuable in treating diseases of children. In the young, the immature nervous centers suffer more severely, and we find the opposite conditions, of irritation with determination of blood, and atony with congestion. The symptoms calling for the use of Belladonna are usually very plain: the patient is dull and stupid - and the child drowsy, and sleeps with its eyes partly open; the countenance expressionless; the eyes are dull, and the pupils dilated, or immobile; whilst as it continues respiration becomes affected, and the blood imperfectly aerated. As these are mostly febrile cases, or at least have a feeble, frequent circulation as an element, I give Aconite in the usual doses. Not that it will cure every case, but those in which an enfeeblement of the pelvic circulation is the principal cause. Of course, it gives no relief where the incontinence arises from vesical irritation. The dose in this case will be the same as above named, but only repeated four times a day. Belladonna is also a specific in diabetes insipidus; even a Belladonna plaster across the loins being sufficient in many cases for its arrest. Belladonna is undoubtedly a prophylactic against scarlatina, as I have thoroughly proven in my practice. Belladonna has other special uses, but they may be briefly summed up: if in any case there is an enfeebled circulation, with stasis of blood, Belladonna is the remedy. Of course, acting upon some parts more directly than others, its influence will be more decided, but there is no case, with condition as above, in which it will not be beneficial. I may say in conclusion, that we want a good preparation of the recent herb; and then it must be used in small doses to obtain the influences named. As we have had occasion to say before, the druggists care little about the quality of medicines sold; they are simply articles of merchandise, and there is little, if any, professional esprit with them, to aid us in having them good.
