The stomachic ulcer is one type of peptic ulcer, it has become a concern since the last state. In the yesteryear, managed peptic ulcer diseases with surgery was the most common method of intervention. However, the incidence of peptic ulcer and decease rate were still high. A peptic ulcer has affected the digestive system which including the tummy, the gorge and the duodenum. Harmonizing to the place of the sore, to identity it belongs to gastric ulcer or duodenal ulcer. In developed states, for case, the Unite State, one of 10 persons suffer a peptic ulcer, on other other manus, stomachic ulcer is often seen in Asia state, particularly in Japan ( Yuan et al. , 2006 ) . Three-decade ago, there were over 90 per centum of patients were diagnosed duodenal ulcers, and 70 per centums of patients were with stomachic ulcers. There are two basic causes which result patients peptic ulcer, one is Helicobacter pylori infection, another is utilizing nonsteroidal anti-inflammatory drugs, such as acetylsalicylic acid.
In this essay, it will be examined what is stomachic ulcer, so depicting what are its causative agents. Furthermore, giving more inside informations about disease information, including the symptoms of stomachic ulcer, and impacts of the tummy. In add-on, it will explicate how hosts response when the tissue and organ alterations by a stomachic ulcer, when human organic structures detects the harm how its defence and how the fix mechanism heals damage cells and tissues. In this essay, it besides will give more information about the diagnosing methods of stomachic ulcer. Last, it will so bespeak how therapies can be used to against the stomachic ulcer.
A stomachic ulcer frequently occurs on the smaller curvature of the tummy. It forms lone or multiple lesions in the tummy liner ( Mardisty, 1921 ) .
In the tummy, it accounts for a natural barrier which is produced by some cells of the interior liner to protect the liner of the tummy and duodenum. It balances the secernment of stomachic acid and pepsin. When the balance has been damaged, a stomachic ulcer may develop. The feature of stomachic ulcer may be an ague or chronic but it may repeat over and over once more. One of the important character is abdomen hurting. However, each patient has the different degree tolerance of hurting, it is difficult to set up a regulation to mensurate the tolerance of hurting. Some patients may experience uncomfortable, some of them describe the hurting lasts invariably. It depends on their description about the hurting, normally it is described like gnawing or combustion hurting, dull hurting, causalgia or pang ( Richards, 1920 ) . Besides that, it is defined that there are two chief causes result in a stomachic ulcer, one is Helicobacter pylori infection, another is taking non-steroidal anti-inflammatory drugs, both of them damage epithielial cells and the mucous secretion bed of the tummy, so organizing the redness and tissue lesions. However, it believe that intaking inordinate stimulating nutrient or caffeine, or emphasis may besides do a stomachic ulcer. A stomachic ulcer does non ever uncover venters pain or accompany other complication symdroms such as: hematemesis or perforation, hence, persons need to make physical medical examination on a regular basis to forestall from enduring stomachic ulcer.

In the yesteryear, it was hard to place what is the cause to bring on a stomachic ulcers. It was assumed that the mucous secretion has been damaged by acid and pepsin to organize a surface lesion of the liner of the tummy. It was believed that the causes of stomachic ulcer were based on the patient holding the upset of life manner or under force per unit area.
Even thought Helicobacter pylori have been known for a few decennaries, nevertheless, there is no 1 linked them with GI ulcer. This state of affairs lasted until 1981, two Australian physicians, Dr. Barry J. Marshall and Dr. Robin Warren, they confirmed the Helicobacter pylori is one of the chief causative agents which consequences in GI ulcer. ( Bauer and Meyer, 2011 ) . They assumed that Helicobacter pylori has degraded the map of mucous membrane of the tummy and the duodenum. Furthermore, it causes redness and erodings inside the liner of the tummy.
It is the advanced discovery in the research of GI ulcer which has non merely led to a alteration in assisting persons to rethink the definition of them, but besides renewed the characteristics in the pathology of the GI ulcer.

Harmonizing to ( Lage et al. , 1995 ) Helicobacter pylori used to name Campylobacter pyloridis before 1990. It is defined as a Gram-negative bacteria and microaerophilic micro-organism that relies on O to last. There are about half population in the universe present Helicobacter pylori. Even it causes stomachic ulcer, nevertheless, in most of the affected persons do non show any symptoms. If persons do non accept antibiotic therapy, Helicobacter pylori can be in human tummy during the full life ( Rathbone et al. , 1986 ) .
Even though human absorb many micro-organisms daily, but many of them can non rule the tummy, demuring Helicobacter pylori. H. pylori are taken in with H2O or nutrient. In human tummy, the persons stomachic luminal pH is less than 2, which forms a natural barrier to forestall bacteriums proliferation within the stomachic lms ( Algood and Cover, 2006 ) . The stomachic mucous membrane produces a figure of stuffs such as stomachic sourness, lactoferrin and antibacterial peptides which can restrain the generation of bacteriums ( Yuan et al. , 2006 ) . It prevents generation of bacteriums within the tummy lms. H. pylori is normally defined as a noninvasive bacterial being, because of it does non perforate the epithelial barrier normally.
Visualizing the Helicobacter pylori bacterium with an negatron microscope, it showed that they are curved rod form. They have smooth surfaces and about four to six scourge, each scourge is with a terminal bulb, that is a important character of Helicobacter pylori ( Rathbone et al. , 1986 ) . Flagella enable H. pylori to track the stomachic mucous secretion bed because of their motility ( Algood and Cover, 2006 ) . Some of them may attach to come up of tummy epithelial cells and internalized by epithelial cells ( Algood and Cover, 2006 ) . They were detected in many patients who are with stomachic ulcer, so that H. pylori is considered to be the primary causative agent in most stomachic ulcer instances.
Besides Helicobacter pylori, another cause which consequences in stomachic ulcer is non-steroidal anti-inflammatory drugs, such as acetylsalicylic acid, which causes GI mucosal harm, erodings, ulcers, ulcer complication and hemorrhage ( Yuan et al. , 2006 ) . It slows the mending procedure of stomachic ulcer. Harmonizing to ( Ji and Hu, 2006 ) , NSAIDs inhibit the activity of cycloosygease ( COX ) , and besides indirectly suppress the merchandises of prostaglandin, prostacyclin and thromboxanes to alleviate the inflammatory. However, meanwhile, it inhibits the activity of COX1, moreover, impacting the prostaglandin of mucos membrane ( Ji and Hu, 2006 ) .
Symptoms of stomachic Ulcer
Scaning human stomachic epithelial cells by an negatron microscope, on the left manus side of the image is non-infected cells, on the right manus side of the image which shows infected epithelial cells. ( Bauer and Meyer, 2011 ) .
Although ulcers do non ever uncover symptoms, many patients with stomachic ulcers felt epigastric hurting after taking nutrient one to three hours. The most common ulcer symptom is a gnawing or firing hurting in the venters. In some instances, patients accompanied terrible complications which including hematemesis, shed blooding even daze. Furthermore, a stomachic ulcer may do by the increasing of digestive juice, which imbalance the acid and pepsin production an inordinate sum than they normally do, in the interim, a stomachic ulcer may develop.
Helicobacter pylori induces the stomachic ulcer through acid stimulating. Besides, the psychological factor such as strength besides can ensue a stomachic ulcer.
Gastric ulcers are caused by an instability between tummy acid, an enzyme called pepsin which is the natural defences of the tummy ‘s liner. This instability leads to redness, which can be worsened by taking acetylsalicylic acid and nonsteroidal anti-inflammatory medicines ( NSAIDs ) such as isobutylphenyl propionic acid, and acetylsalicylic acid.
When a patient has these specific symptoms, they can assist to name the stomachic ulcer. The patient who has a stomachic ulcer with epigastric hurting is worse during the dark and may rouse the patient up ( Damjanov, 2009 ) . The hurting can be relieved by alkalizers or milk. He or she felt hurting after taking nutrient two to three hours. Some of stomachic patients may hold bleeding syndrome, because of their tummy have been damaged by lesions. Bleeding is a important character of an acute stomachic ulcer. It may do patients hematemesis and melena. Following that, patients may attach to fainting and anaemia ( Bolton, 1922 ) .
There are two chief causes of the stomachic ulcer, one is Helicobacter pylori another is long-run utilizing nonsteroidal anti-inflammatory drugs.
Disease information aa‚¬ ” organ/tissue/cellular degree ( entire 30 Markss )
What should be included:
A elaborate account of the host responses at the cell, tissue and organ degrees. Include information on cellular responses and versions, and impacts on cellular construction and map.
Explain host defence and fix mechanisms, if any. Explain if the host responses are transient/reversible or if these causes lasting alterations to the cells/tissues. Include information on the pathology and/or cellular characteristics sought for diagnosing.
The stomachic mucous membrane produces a figure of stuffs such as stomachic sourness, lactoferrin and antibacterial peptides which can restrain the generation of bacteriums. The map of the mucosal barrier is to back up normal blood flow, mucus secernment, and protect the surface of the mucous membrane. A stomachic ulcer may besides do by the increasing of digestive juice, which imbalance the acid and pepsin production an inordinate sum than they normally do, in the interim, a stomachic ulcer may develop. It was assumed that due to the mucous secretion has been damaged by acid and pepsin to gnaw mucous secretion membrane, moreover, to organize a surface lesion of the liner of the tummy ( Damjanov, 2009 ) .
Not merely septic H. pylori but besides NSAIDs affect the epithelial cells of the tummy, since that, they have been damaged, and so to organize one or multiple sores inside of the tummy liner. Furthermore, most of patients who have stomachic ulcer may experience discomfortable in their venters, in some instances, patients accompanied terrible complications which including hematemesis, shed blooding even daze. When the patient has those important symptoms which may assist to name the stomachic ulcer or even other peptic ulcers.
There are two types of ague stomachic ulcers:
First, its character is there is a assortment of sizes of the lesions can be seen with X raies, which opens an arteria on. However, they are barely involved the peritoneum. The host can mend these lesions by-self that may take a twosome of hebdomads, and so they are impaired by the organ mechanism.
Second, when the lesions become worse, these lesions penetrate through the mucous secretion bed ( Algood and Cover, 2006 ) . Furthermore, they may spread out the surface of the mucose membrane to organize a big graduated table ulcers. Since that, the chronic ulcer may develop the ague ulcer, but there is a few of the differences which are some of them may mend bit by bit, but still a big part of them are have no capacity to retrieve themselves. Some patients are non cognizant of the stomachic ulcer disease before the specific syndromes occur. They may happen by chance without attach toing any syndromes. The chronic stomachic ulcer may last a few months or even old ages ( Bolton, 1922 ) .
Furthermore, as mentioned antecedently, H. pylori infection causes stomachic ulcer every bit good. H. pylori can be within the human organic structure for a long-run period without being quenched by the immune system ( Bauer and Meyer, 2011 ) . It attacks the host immune system and causes chronic, faineant rednesss. Besides it reduces the thickness of the mucous secretion bed, farther to damage the mucosal defence system. Then weakening mucosal blood flow, and interacting with the stomachic epithelial tissue throughout all phases of the infection. On the other manus, it stimulates stomachic acerb secernment. It induces redness, which increases parietal-cells mass and the capacity of acerb secernment ( Yuan et al. , 2006 ) . Gastric ulcers are caused an instability of tummy acid and an enzyme whose name is called pepsin, and the natural defences of the tummy ‘s liner. This instability leads to redness, which can be worsened by acetylsalicylic acid and nonsteroidal anti-inflammatory drugs ( NSAIDs ) .
However, some patients are non cognizant the stomachic ulcer, because the stomachic ulcer may be in their organic structures without any symptoms. Since that, these amendss cells have developed a big graduated table of lesion in the tummy, bit by bit, these lesions may get down to perforate through the full muscular beds, and to spread from the peritoneal pit to do peritoneal inflammation by a great figure of adhesions palisading off. Furthermore, the perforation may farther widen going a incursion ( Richards, 1920 ) . Furthermore, deep ulcers may perforate through the stomachic wall into the next variety meats, which consequences other organs redness and lesion forming, for case, duodenal ulcer ( Damjanov, 2009 ) .
Diagnostic methods aa‚¬ ” efficaciousness, advantages, restraints and/or jobs ( entire 15 Markss )
In the yesteryear, it admitted that there is a trouble to name the stomachic ulcer, because of the incomplete etiology. In order to get the better of this obstruction, utilizing the X raies can turn up to the place of the lesion, and attach to the specific symptom to name stomachic ulcer. Tenderness is a important mark in stomachic ulcer diagnosing. The haematemesis and perforation were the primary indicant. Since that, repeating hurting and emesis were besides defined as the symptom of stomachic ulcer. However, it had been debated that due to there is a assortment of strivings in the history,
The character of stomachic ulcer is the relation of hurting to nutrient, some patients felt worse after taking nutrient ( Mardisty, 1921 ) . On the other manus, some patients felt changeless hurting or non affected after taking nutrient.
Gastric ulcers are caused an instability of tummy acid and an enzyme whose name is called pepsin, and the natural defences of the tummy ‘s liner.
This instability leads to redness, which can be worsened by acetylsalicylic acid and nonsteroidal anti-inflammatory drugs ( NSAIDs ) .
There are many high hazardous factors may do stomachic ulcer including:
Taking acetylsalicylic acid and nonsteroidal anti-inflammatory drugs, Helicobacter pylori infection, chronic gastritis, smoke, age addition, certain blood curdling job.
However, braid does non decline stomachic ulcers.
When a patient is with these specific symptoms, these can assist to acknowledge the stomachic ulcer. The patient may rouse up at dark with abdominal hurting. The hurting can be relieved by alkalizers or milk. He or she felt hurting after taking nutrient two to three hours. Vomiting blood, particularly. Blood in stools or black. Weight loss and felt weariness.
The history provides a hint when patients are with hematemesis or perforation.
Perforation means the tummy wall may be penetrated by stomachic ulcers. The ulcers have perforated through all of the muscular beds, and is separated from the general peritoneal pit and cause peritoneal inflammation. Furthermore, when the ulcers penetrate through the tummy wall into the nearby variety meats, which is called incursion. That is the typical stomachic ulcer syndrome ( Richards, 1920 ) .
There are a figure of symptoms which including epigastric hurting, nocturnal hurting, or experiencing discomfortable after taking nutrient. Those are helpful to name stomachic ulcer disease. Some of patients vomit blood. However, there is no specific symptom can used to reorganise the difference the infection cause is from NSAID or H. pylori infection ( Yuan et al. , 2006 ) .
The X ray has non merely advantages in diagnosing, because it provides information of an accurate diagnosing, but besides benefit to turn up the lesion of stomachic ulcer.
There are several techniques are used to observe the H. pylori infection presents.
H. pylori G Enzyme-Linked Immunosorbent Assays ( ELISA ) can be used to observe the presence of Helicobacter pylori in patientsaa‚¬a„? serum. It relies on the anti-gent to observe the anti-body. Serology test merely can be used in vitro diagnosing, when it detects the presence of H. pylori the reagent will uncover a interaction but it can non place active infection ( Aro et al. , 2006 ) .
Before the advanced diagnostic techniques are developed, the biopsy still is the most normally used in many research labs.
Harmonizing to a figure of clinical surveies research, normally these biopsy samples were obtained from patients who are with stomachic ulcer to name H. pylori infection. They were stained with Giemsa to detect the presence of bacteriums.
The endoscopy relies on a device which made of a little and flexible tubing with a visible radiation and a camera lens at the terminal to analyze the epithelial cell alterations of the digestive variety meats. It is helpful to distinguish an accurate stomachic ulcer and or ulcer complication. It is efficient to command hemorrhage of the tummy ( Aro et al. , 2006 ) .
Non endoscopic trials include the C-urea or C- urea breath trial. UBT is the most efficient method which used isotopes to observe an active infection. The sensitiveness and specificity of UBT may be inhibited by PPI or antibiotic intervention.
Therapy aa‚¬ ” effects on cells and tissues ( entire 10 Markss )
Due to H. pylori infection is the most common cause in patients who are with GI ulcers. Eradication of H. pylori therapy histories for antimicrobic agents combined with antisecretory drugs. It admitted that obliteration of H. pylori intervention is expeditiously for many patients who has duodenal ulcers. However, there is no important consequence on ulcer healing. To compare to the mending rate of stomachic ulcer and duodenal ulcers, the former public presentation was lower than the latter. It can be assumed that even some stomachic patients cause by H. pylori infection, nevertheless, that does non intend it will hold the same consequence as duodenal ulcer healing.
There is no grounds to demo that obliteration of H. pylori accelerate ulcer healing or prevent ulcer return ( Ji and Hu, 2006 ) .
Proton pump inhibitor ( PPI ) is used dainty for stomachic ulcer. It remains the pH at 6 within the tummy and block tummy acid production by halting the tummy ‘s acid pump.In order to extinguish the H. pylori, a three-base hit therapy which contains a proton pump inhibitor, Amoxil, and clarithromycin. It has a singular consequence to cut down the repeating rate of gastric ulcer which has been proved in a figure of clinical surveies.
Couple to the intervention with clarithromycin has been used widely, the rate of H. pylori infection has been reduced than of all time ( Hiraishi et al. , 2010 ) .
Stop taking NSAIDs, it has been a concern that it causes GI mucosal harm, erodings, ulcers, ulcer complication and hemorrhage. Surgery- while the medicine and endoscopy do non work with the patients, they may necessitate to make surgery to take the lesion tissues of the tummy ( Aro et al. , 2006 ) .
Decisions ( entire 10 Markss )
To sum up, stomachic ulcer is defined as a type of GI ulcer. Due to the development of intervention and therapies, patients healed within a few twosome of hebdomads. There are two chief causative agent one is the H. pylori infection, another is the NSAIDs usage. The former consequence in the mucous secretion bed has been damaged further forming lesions on the tummy liner. There are two sorts of stomachic ulcer, one is acute stomachic ulcer which accompanies strivings and complications such as hematemesis and perforation, another is chronic stomachic ulcer, it may do little lesion and epithelial cell amendss for a long clip until patients start experiencing uncomfortable with venters pain and complications.
Ulcer does non ever uncover symptoms, but most of stomachic ulcer patients may experience venters trouble sometimes is the important character of stomachic ulcer, moreover, in some instances, it causes serve complication such as hematemesis and perforation.
Due to the find of the causative agent of stomachic ulcer which is H. pylori and reasoning unsuitably utilizing NSAID, today, there are more detection methods are developed, such as x-ray, endoscopy and serology trial. Those are helpful and efficient in diagnosing the stomachic ulcer. From that, after many laboratory experimental research and clinical trials, stomachic ulcer can be cured good by medical therapy and surgery. Even though it occurs sometimes in many persons, nevertheless, the incidence and decease rate have been reduced and controlled than of all time.
