It is indicated when the vision is quite good and where facilities for keratoplasty are not available Optical iridectomy Site 1 medicine abuse cheap bimat 3 ml line. Full thickness keratoplasty is preferred treatment when the ulcer has healed and the vision is markedly reduced abro oil treatment discount bimat 3 ml mastercard. Tattooing with gold (brown) or platinum (black) is advised for cosmetic purpose only in firm blind eyes usually medicine zyprexa buy bimat on line amex. A piece of blotting paper of the same size medicine 802 discount bimat 3 ml without a prescription, soaked in fresh 2% platinum chloride solution is kept over the opacity. On removing this filter paper, few drops of fresh 2% hydrazine hydrate solution are applied over the area which in turn becomes black. Corneal fistulaFull thickness keratoplasty is indicated as the fistulous tract is lined by the epithelium which prevents healing. It is important to note that hypopyon is sterile as the leucocytosis is due to the toxins and not by actual invasion of the bacteria. Pneumococcus, Pseudomonas pyocyanea, Staphylococcus, Streptococcus, Gonococcus, Moraxella, fungus, etc. Resistance of the hostIt is commonly seen in old, debilitated, alcoholic, malnourished and immunologically deficient persons. Chronic dacryocystitis is a continuous source of infection particularly of Pseudomonas pyocyanea and pneumococcus bacteria. In case of a corneal ulcer there is always associated iridocyclitis due to the liberation of toxins by the bacteria, which diffuses into the anterior chamber via the endothelium. This results in dilatation of the blood vessels and outpouring of leucocytes which become enmeshed in the fibrin network. Such hypopyons are fluid and change their position with gravity when the patients head is changed. In severe cases, it may completely fill the anterior chamber thus obscuring the iris. The hypopyon is sterile and it usually gets absorbed when hypopyon corneal ulcer is adequately treated with routine treatment for corneal ulcer. The opacity is greater at the advancing edge in one particular direction than centre. The tissues breakdown on the side of the densest infiltration (yellow crescent) and ulcer spreads in size and depth. Often there is infiltration anterior to Descemets membrane at the floor of the ulcer while the intervening stroma is normal. Marked iritis with cloudy aqueous (hypopyon), conjunctival and ciliary congestion is usually present. Panophthalmitis may occur due to rapid growth and spread of the virulent organisms. Perforation may heal resulting in leucoma, adherent leucoma, anterior staphyloma or occlusio pupillae causing marked visual impairment. Treatment It is a well-known surgical rule that pus anywhere in the body has to be removed. Early and intensive treatment of corneal ulcer as mentioned earlier is started at once after culture and sensitivity. Secondary glaucoma is the most common cause of failure of treatment in elderly persons. It is treated by Topical atropine 1% the Cornea 121 Oral acetazolamide (carbonic anhydrase inhibitor) Intravenous mannitol 20%, 200 ml (hyperosmotic agent) Paracentesis helps in lowering the tension and brings fresh aqueous and nutrient. Etiology It is commonly caused by Candida albicans, Aspergillus fumigatus, Fusarium, Cephalosporium, Streptothrix actinomycosis, etc. Fungal corneal ulcer Symptoms these are same as for the bacterial ulcer but they are less prominent than equal-sized bacterial ulcer. There is mild pain, irritation, watering and presence of yellow patch in the cornea. It is dry in appearance with small satellite lesions around the ulcer due to the stromal infiltration with delicate feathery, finger-like hyphate edges protruding into adjacent stroma. Predisposing factors Non-specific Systemic immunosuppressives, local or systemic steroids therapy 4. Marked infiltration Hyphate margins, satellite with gross destruction lesions, immune ring of tissue iv. Slit-lamp examinationEndothelial plaque and immune ring may be seen around the ulcer. Diagnosis Scraping of the ulcer at the margin and inoculation of media should be done promptly. As the organism is often situated deep within the stroma, corneal biopsy may be taken at times. Culture in Sabourauds medium, blood-agar plate or brain-heart infusion broth is essential. Antifungal drugsThe role of these drugs is limited due to the few approved antifungal drugs and their poor penetration. Topical antifungals are to be instilled for a long-time, as the response is often delayed. Taper over several weeks Subconjunctival100 -300 mg on alternate day 1-2 doses Intravitreal5-10 g SystemicBy infusion, 5-10 mg total dose is given/day. SystemicSystemic antifungals are indicated if the infection spreads to the sclera and there is impending perforation. Cycloplegics such as atropine is used to prevent posterior synechiae formation and to control iritis by paralysing the ciliary muscle. Therapeutic full-thickness keratoplasty is much better solution in cases of non-healing fungal keratitis. Deep marginal ulcer may occur rarely in cases of polyarteritis nodosa, systemic lupus erythematosus due to antigen-antibody complexes. Marginal ulcer Chemical cautery may be done with 1% silver nitrate in mild recurrent ulcers. Etiology It occurs as a result of degenerative process due to ischaemia of cornea. Characteristic white overhanging edges are seen as the ulcer spreads below the epithelium and superficial layers of stroma. Rodent ulcer the Cornea 125 Treatment It is very difficult because of corneal ischaemia. Excision of 4-6 mm strip of adjacent conjunctiva with or without cryotherapy is often effective. Etiology this condition is commonly seen, In eyes insufficiently covered by the lids due to paralysis of the orbicularis muscle. Sign There is corneal erosion with ulcer formation as the epithelium becomes desiccated. It occurs typically as a result of injecting alcohol in gasserian ganglion in cases of trigeminal neuralgia. History of trauma Common with Vegetative matter penetrating injury injury Signs 1. Ulcer Central disc with Typical dendritic and Dry yellow-grey necrotic material geographical pattern with satellite lesions 4. Primary ocular herpesThere is acute follicular keratoconjunctivitis with regional lymphadenitis and skin involvement. Recurrent herpesIt has following characteristic features: Epithelial ulcers Stromal interstitial keratitis Disciform keratitis Iridocyclitis. Superficial punctate keratitis Numerous, white plaques of epithelial cells are present all over the corneal surface. Dendritic ulcerErosions coalesce to form typical dendritic figure like liverwort. Complications Chronic epithelial ulcer with recurrence is a common complication. Tissue biopsy and tissue cultureElementary bodies are seen with suitable staining. Treatment should not be prolonged beyond 3 weeks since this may lead to corneal toxicity. Adenine arabinoside (Ara A) and vidarabine (Vira-A) 3% ointmentIt is not effective in stromal disease.
For children diagnosed with T1D that way while still getting support treatment yeast overgrowth bimat 3ml otc, advice treatment interstitial cystitis generic 3 ml bimat with visa, and care from their long ago medications 3605 buy bimat mastercard, most if not all are doing their own injections or parents symptoms vaginitis purchase 3ml bimat. Teens should try to be vocal about what they need and pump-site changes and fnger pricks at this point. In just about every case, parents are managing the medical supplies, prescriptions, and medical appointments. Teen Toolkit | 33 It means a lot to parents for their teens with T1D to keep them The frst step toward knowing is simple: ask your teen. Having teens keep tabs on their T1D, for the is happy with her care and feels comfortable, there is no need frst time, can be scary for parents. But if she feels like she needs something new, it their meters or pumps available for review from time to time or could be a good time to transition to adult care (most adult copy their parents on emails and other communications to the endocrinologists want their patients to be 18 years old or medical team are going to be the ones who help their parents to nearly that age). Its a process for the Some teens with T1D fnd that adult endocrinologists (and parents as much as the teens, so there are little things that teens make sure its an endocrinologist who specializes in T1D) have with T1D can do for their parents, too. Most teens are ready to do their own shots T1D moves toward college age, subjects such as birth control, from the start and learn about their disease in a much more alcohol, and other adult situations need to be not just discussed meaningful way than small children can. The step confdent in it alland they may remain that waythere is toward an adult practice may be his frst giant leap toward always a time when they need their parents to understand. If you need additional guidance in this area, the Helping parents learn along with them will help for a lifetime. Its not unusual for teens to come home from college and When to say no want their parents to take over their T1D care for a few days. Perhaps they want their parents to give them their injections So what if your teen with T1D wants almost total or calculate insulin doses for them. This is an indication that independence, and you see her take a turn for the worse Imagine the stress of managing T1D along all, as much as a teen may dream of no more nagging from with studying, making new friends, writing papers, and taking Mom, Dad, or whoever is the adult in her life, the constant job exams. And Changing medical teams the teen, thirsty for independence and maturity, may not want Most pediatric endocrinology groups will allow a patient to to admit that. Large swings teens and young adults with T1D choose to stay with the same in HbA1c levels are one red fag. Dont forget teens are going to have a harder But there are some things to consider. Goodness knows, and experiences of teens and young adults with T1D are very a parent cannot be around to count carbohydrates for a teen at diferent than those of smaller children. However, a parent can fnd experience with older teens, you may want to discuss with wayswith the help of the medical teamto make sure high the teamand your teenhow you will navigate this new blood-sugar levels are corrected in a reasonable amount of time time. The team should have a plan (fnd other practices to and low ones are avoided as much as possible. While transition should be a slow one; sometimes it might involve you, as a parent, may love the medical practice that you have taking a step backward for a while. The goal, of course, is to been going to for years, sometimes a teen just feels like he send a teen with T1D to college with healthy self-care practices. The best thing to do is to let him know you It was a slow process throughout high school. It wasnt like a do know what the truth is and that you need him to just tell one-time deal. Remind him of your promise to for short test drives with your parents, who are watching your always help him when he needs it and not punish him instead. Eventually, you prove that you wont crash the car Tell him you know that youd struggle too, if you had to do and you are given the keys. Create a place of trust for him, so that you in kind of responsibility [T1D self-care] on a kid, and even then turn can trust him outside of that space. I only wish my internal organs came with it takes incredible reserve from parents. She may think that diabetes supplies magically appear in the Tere are cases where you have to take action though, such cabinet/closet/shelf every 30 to 90 days, but at some point she as any situation that puts your teen, or others, in immediate will have to know how to obtain them independently. Tings like drinking too much alcohol with T1D your teen would like to take on the responsibility of ordering (particularly when underage) or completely ignoring all their supplies during college (if the teen is not going to college, this diabetes needs mean a parent has to step in. But do remember that an Let him know the steps that are involved and that you will occasional missed bolus or a slightly elevated HbA1c level is talk about it again at a future date. When your teen is aware that diabetes supplies are very expensive, in doubt, call your teens medical care team before talking to so having a good job with health insurance will be crucial your teen and share the situation with these professionals. Tese are big topics for a teen, and its should be able to help you know how to react and what to say. If they are an experienced team, they are likely to have seen Trust and independence and managed all this before. Of course, this is all about trust, but it is also about In the end, your teen with T1D will most likely go of to compromise. We all want to trust our teens to do the right college, trade school, or work, and eventually live on her own. But It is, afer all, the sign of a good parent when a child grows up they, like us, are human. Tink about the adult who tries to go and moves on to an independent and successful life. Falling of a bit on T1D care is really not in their lives, your children are always going to need you and that diferent. Your best understanding how to help them without hindering them is a bet is to push honesty as much as you can. The teen who can come to an adult and admit she is having trouble is the teen who will move toward independence more smoothly and with fewer bumps. True, it may be that our the goal, reach out to folks, get friends to join in, and most of teens dont really care about much past the homecoming dance all, learn the message and the goal of the organization that they on Friday or the party at a friends on Saturday that everyone is are walking for. Now there are many insulins, fast meters, You can also encourage your teen to be a mentor to younger great pumps, and even continuous glucose monitors. But they are proof that we are more about his own care than helping a little one get a grasp moving, step by step, to a better world for people living with on things. Ofen, those friendships are as benefcial to the teens T1D, and yes, toward a cure. Show her the stats that show that the lifespan of people with T1D is The teen with T1D has that opportunity right in front of her.

Discount 3 ml bimat with mastercard. [131010] SHINee (샤이니) - Symptoms (상사병) + Everybody @ MNet MCountdown.
In m any anim als symptoms type 1 diabetes buy generic bimat line, the cause is often not apparent medications on carry on luggage buy bimat 3 ml overnight delivery, but in some there is a com plete rough band o f connective tissue that m ay encircle the aortic outflow ju st under the aortic valve itself medicine keeper order 3ml bimat visa. This band o f tissue is a congenital anom aly called a com plete subaortic stenotic ring medications used to treat bipolar discount bimat on line. In some an imals w ith lung disease, intrapulm onic, diffuse vascular disease, stenosis, or other pulm onic valve disease only the right ventricular wall (cor pul m onale) is hypertrophied. Vegetative endocarditis o f specific heart valves can be causative in any species. In alm ost any sized dom estic cat, the heart w eight is alm ost never above 17 gram s normally, but in this entity o f cardiom yopathy it is usually significantly heavier. In some cases, the heart m ay be heavier w ithout clinical disease but it is thought that with tim e the clinical signs will comm ence. The lum en o f both atria and auricles m ay be up to 2 to 4 tim es norm al size, w ith the ventricles less dilated. When dilation exceeds the ability o f the atrioventricular valves to close completely, regurgitation occurs w ith subsequent heart fail ure. In m any cases, com pensatory m yocardial hypertrophy m ay oc cur bilaterally, or even unilaterally. Several breeds o f dogs such as the Doberm an pinscher and w ater dogs are m ore affected than oth er breeds. The norm al heart w eight o f m ost dom estic cats is under 17 gram s but in this disease the heart w eight m ay be doubled or more. Septal H eart Defects In the position (A) above, small openings m ay be found at birth that will often close spontaneously w ith age. Actually, some m assive openings m ay let anim als survive to old age, but it is rare. Low septal defects betw een the ventricles (near the apex) are more com m on in lam bs than in other species. Scat tered m ineralization on other endocardial surfaces and som etim es on the endothelium o f m ajor vessels are diagnostic for urem ia as the result o f renal failure. M ore extensive, sim ilar m ineral depos its m ay be seen w ith vitam in D poisoning and other plant-related poisonings, and some therapeutic drugs. A relatively new recogni tion o f an extensive m ineralization can be seen in som e cases o f hypercalcem ia o f m alignancy. These are associated w ith various m alignancies, especially adenocarcinom as o f anal sac glands in dogs and lym phosarcom a in m any species. Aortic Rupture the usual finding in aortic rupture is a V-shaped irregular rupture at the base o f the aorta, w ith the apex located at an aortic cusp leaflet attach m ent site. The rupture occurs with hem orrhage through this tear into the septal wall itself, the periaortic soft tissues, or even into the pericardial sac. Care m ust be taken during the dissection, as it m ay occur at any site around the aortic ring and be destroyed during the necropsy. Horse: M ost cases that occur in horses have a com m on finding o f trau m a to the chest as in: stud horses falling onto the rump o f the mares during service; racers tripping during a race and falling on their chest; or horses being shot in the head for euthanasia purposes and collapsing rapidly, to fall on their chest. Each o f these cases cause kinking o f the heart and aorta probably at high systole, when all valves were closed and the w eak link o f that system being the aortic valve attachm ent site. Aortic ruptures in young anim als, including the horse, can be associated with traum a and also copper deficiency. Commonly, w ith traum a they will be found alm ost anyw here along the aorta or other large vessels, however; and, not so specifically, at the aortic cusp attachm ents site. Locations o f Com m on Vegetative Endocarditis Lesions From tiny to extrem ely large, friable, often dull, irregular m asses are attached to any valve and even the endocardial walls. The masses contain som e heavy, pale, yellow, green, or even black foul-sm elling bacterial m aterial in their centers o f necrotic, purulent debris. These are evidence o f vegetative endocarditis, being the result o f a bacteri al, rarely mycotic, inflam m ation o f the endocardium o f the w alls or heart valves proper. M ost, by far in any species, are associated with heart anom alies, chronic joint disease, or chronic infection anyw here in the body. Each o f these account for about 30% o f such cases, leav ing approxim ately 10% to be caused by a specific organism such as Erysipelas rhusiopathii in pigs, Streptococcus viridens in the cap tured opossum, and A spergillosis in dogs. In m any instances, with septic throm bi as these in the left heart near the coronary artery open ings, they m ay em bolize to the heart proper. Focal fibrinonecrotic and em physem atous m yositis (blackleg) with associated odor o f sour milk. O ther H eart-A ssociated Infections H ardw are-caused m yocarditis, or endocarditis, or both can be associated with m any different organism s in cattle. It is difficult to explain the pathogenesis o f blackleg in the m yocardial form o f the disease as m any consider blackleg as starting de novo from the bacterial spores present in the m uscle cells before they are damaged. It is o f some in terest that the hardw are metal, usually wire, found in the m ajority o f hard w are penetrations to the heart from the reticulum, are about 6 -1 2 cm long, w ith a curve tow ards one end. N onseptic Fibrin Throm bosis N onseptic fibrin throm bi are the response to endocardial damage, w hich is different from the m ore com m on bacte rial vegetative endocardial throm bosis. Likely causes in clude term inal endocardial suffusion hem orrhages and en docardial rupture from intralum inal pressure associated w ith incom petent valves, either from anom alies at birth or acquired at a later age. Several or all cham bers m ay be dilated w ith a definite pale to gray, glistening, slightly thickened endocardium. The term subendocardial fibroelastosis describes the histological fea tures well. These affected atria m ay rupture, at least superficially, with crooked linear stretch tears developing. These irregular endocardial stretch tears m ay develop nonseptic fibrin throm bi along the tear itself. Acute Valvular Edem a In all species, it is very com m on to find slightly elevated blebs o f clear edem a at the base o f m ost heart valves. M ost can be considered a functional change, w ith a slow death as w ith some euthanasias. M ost w ould not be significant and certainly should not be considered verrucous endocardiosis (chronic valvular fibrosis), w hich are at the free edge o f the valve cusps, nor vegetative endocarditis (irregular, fragile). The nodules consist o f connective tissue, myxoid degen eration, edem a, and intimal proliferation. These are degenerate changes and, often, as the anim als age they becom e more prom i nent and deform the valve to com prom ise its function enough to be the m ost com m on form o f heart disease in older dogs. They extend into the pulm onary artery and backw ard into the posterior vena cava. These parasites usu ally do not cause lesions in the heart proper, but m ultiple irregular intimal thickenings to the pulm onary trunk and its branches m ay be seen. D ead or degenerate adult w orm s m ay em bolize to the lung and cause some vascular com prom ise to the lung. They usually do not cause true infarcts in the lungs because the lung has a dual blood sup ply. W P 1396, 1770 Dog/Cat: D irofilaria immitus are more com m on in som e geographic areas than in others. H eart M asses Large or small, pale tan, relatively soft m asses scattered in the m yocardi um. Especially in the right atrium and auricle, heart m asses are m ost likely lym phosarcom a in any species. W P 1678, 1744 Ox: Pale white, firm m asses, often elongated, around the base or endocar dium are m ost likely neurofibrom as, especially in the ox. Dog: H ighly vascular m asses, or elongated polypoid soft fleshy m asses, at tached to the right auricle inside or outside, are m ost likely hem angiosarco mas. Firm masses at the base o f the heart and betw een the aorta and pulm o nary artery, often with local spread in the pericardial cavity, are aortic body tum ors (chem odectom as). Such highly vascular m asses m ay be seen in the liver and spleen o f these cases, but it m ay still be difficult to accurately determ ine the prim ary tum or o f origin o f the m etastases. Often, associated vessels rupture and cause fatal tam ponade (bleed-out into the heart sac, heart m uscle, or m ediastinum). Note: In som e species, tum ors at the base o f the heart may also be thyroid tumors. These occur as a result o f vestigial rem nants being ectopic and thus m ore likely than norm al tissues to becom e neoplastic. One suspects that the anoxia com m on to the right auricle may have som e relationship to the high incidence o f certain tumors, as lym phosarcom a and hem angiosarcom a de veloping in such a low m etabolic tissue. Locally Extensive D egeneration In m ost young dom estic farm anim als, opaque w hite linear patches o f m uscle in any part o f the heart, often w ith a sharp line o f dem arca tion, can be diagnostic for nutritional m uscular dystrophy (white m uscle disease) as a result o f this vitam in E/Se responsive disease.

It is manifest clinically through a set of largely non-specific symptoms such as early satiety, bloating, nausea, anorexia, vomiting, abdominal pain, and weight loss. Common causes include diabetes mellitus, prior gastric surgery with or without vagotomy, a preceding infectious illness, pseudo-obstruction, collagen vascular disorders, and anorexia nervosa. Gastroparesis often presents as a subclinical disorder; hence there is no true estimate of its incidence or prevalence. However, it has been reported that between 30-50% of diabetics suffer from delayed gastric emptying. Location of the stomach in the body Gastric Motor Physiology Normal gastric motility/emptying requires an integrated, coordinated interplay between the sympathetic, parasympathetic, and intrinsic-gut (enteric) nervous systems, and the gastrointestinal smooth muscle cells. Disturbance at any level has the potential to alter gastric function, and ultimately affect gastric emptying. To better understand gastric motility, it is important to be familiar with both the functional zones and the major digestive functions of the stomach including the difference between an empty and a full stomach. The proximal stomach comprises the cardia, fundus, and bodyand is characterized by a thin layer of muscle that produces relatively weak contractions. Upon the ingestion of food, the proximal stomach exhibits receptive relaxation, with very little increase in intragastric pressure. The distal stomach consists of the antrum and pylorusand is characterized by a thick and powerful muscular wall. The pattern of contraction in the distal stomach also regulates the rate at which partially digested food is emptied into the duodenum. Mechanical and enzymatic breakdown of larger particles into smaller particles (< 2 mm), known as chyme. Slow delivery of chyme to the duodenum at a rate not to exceed the digestive and absorptive capacity of the small intestine. The Empty Stomach Following digestion and absorption of a meal, contractions persist in the empty stomach and small intenstine. These appear after 12-24 hours of fasting and may be related to low blood glucose levels. Receptive relaxation facilitates food storage, allowing the proximal stomach (fundus and proximal corpus) to relax and increase its volume up to 15 times its empty state with very little increase in intragastric pressure (< 5 mmHg). These slow waves originate in the pacemaker-cells (interstitial cells of Cajal) in the mid-portion of the greater curvature (the proximal corpus), and travel distally towards the pylorus at a frequency of about 3/minute. Propagating at a slightly faster velocity along the greater curve than along the lesser curve, the contraction waves reach the pylorus simultaneously (Figure 3). In the proximal stomach (fundus), contraction waves propagate more slowly (< 1 cm/sec) and are quite weak. This allows some mixing of ingested food and gastric secretions, but more importantly, serves to facilitate food storage. In the early stages of the antral contraction cycle, the pylorus is open, thus allowing a few ml of gastric chyme to be propelled into the duodenum. This is soon followed by a forceful pyloric closure (as the wave reaches the pyloric sphincter), forcing intragastric contents back into the antrum and corpus. This retropulsion is referred to as the pyloric pump, and serves to effectively mix food and gastric secretions, and to grind gastric contents into chyme. Solids have to be reduced to between 1-2mm in size before they can be successfully delivered to the duodenum. As a consequence, relatively large, indigestible solids remain in the stomach unless they are eliminated by vomition. This potential, however, is unstable and oscillates rhythmically by 10-15 mV intervals over a uniform time course. In due course, these depolarizations propagate to adjacent cells through gap junctions (Figure 4). Spontaneous slow waves result from a balanced inward depolarizing Ca flux and a repolarizing K efflux. Whether or not muscle cells respond to these basal depolarizations and contract is largely dictated by neural and hormonal mechanisms. Control of Gastric Motility Myogenic Mechanisms All of the stomachs smooth muscle cells have the ability to produce electric depolarizations (slow waves) from resting potential. These rhythmic contractions are thought to originate in the non-smooth muscle pacer cells, (possibly, in the interstitial cells of Cajal). However, because there exists a gradient in the resting membrane potential between the different segmentsfrom -50 mV at the fundus to -80 mV at the pylorusthe frequency of contractions in the antral portion of the stomach is less than that at the corpus. The slow waves initiated in the pacer cells (of the greater curvature) do not spread to the more proximal fundus because it has a less negative resting membrane potential among other myoelectric characteristics limiting its excitability. Nitric Oxide), and adrenergic neurons have an inhibitory influence on fundic contractions. Two properties control the propagation of contractions in the rest of the stomach: 1) the gradient in slow wave intrinsic frequencies in different segments (corpus>antrum>pylorus), and 2) the conduction velocity of the action potential of different segments (4 cm/sec in the distal antrum vs. Neurohumoral Mechanisms In the proximal stomach, receptive relaxation is mediated through stimulation of mechanoreceptors. These mechanoreceptors initiate a vago-vagal reflex arc via the tractus solitarius neurons. This, then, is the basis for the decrease in gastric accommodation, and gastric compliance (increased luminal pressure) post-vagotomy. Some evidence also suggests a role for vagal fibers in maintaining basal fundic tone. More distal regions of the intestinal tract reflexly modulate fundic contractility. This reflex is diminished by either vagotomy or splanchnicectomy, and abolished if both are severed. Both consistency and composition of a meal are key in determining contraction amplitude: particulate foods induce more powerful antral contractions than homogenized foods, and meals of higher caloric content induce a more prolonged contractile response (fats > proteins > carbohydrates). Neurohumoral factors control the fed state, although the specific mediators are still unknown. It is known that vagal pathways are implicated, as vagotomy increases the threshold for contraction initiation, and shortens its duration.
