Recommended: Acute and chronic inflammation

Inflammation could be defined as a medium by which the body tissues respond to all sorts of injury (Roitt, 1997). It is a defence mechanism against infection from injuries. Physical stimuli such as change in temperature, UV radiation, or skin irritation may cause release of inflammatory mediators such as cytokines that ensure the immune system provide suitable defence, chemokine that bring leukocytes to the inflammation site, eicosanoids, neuropeptides, etc. Inflammation could be acute or chronic. Acute inflammation is an immediate response to trauma; in which the body fights against foreign bodies and heal wounds. Inflammatory mediators are released from the cell, causing immune response. Vasolidation is another stage in acute inflammation; it causes increased blood flow and thus increases permeability of the blood vessels, which then result to the release of plasma protein into the affected tissues (Spector & Willoughby, 1963). It could be characterised by the redness, swelling and increased heat in the affected area. After vasolidation, the inflammatory cells penetrate the injured tissue because of increased permeability. Mast cells are responsible for releasing mediators like cytokine and chemokine that gets rid of dead cells and toxins. This is followed by the release of other important mediators by the endothelial cells. In order to make the inflammatory response effective, leukocytes, other mediators such as Leukotriene and Kinins. Ones chemokine brings leukocytes to the inflammation site, plasma proteins capable of destroying pathogenic agents are initiated, the injury begins to heal, and then acute inflammation ceases. Under normal conditions, the inflammatory response is deactivated by anti-inflammatory mechanisms to avo...

  • Pathophysiology of Sepsis Inflammatory Response

    987 Words  | 2 Pages

    Sepsis is defined as an exaggerated, overwhelming and uncontrolled systemic inflammatory response to an initially localised infection or tissue injury, which may lead to severe sepsis and septic shock if left untreated (Daniels, 2009; Robson & Daniels, 2013; Dellinger et al, 2013; Perman, Goyal & Gaieski, 2012; Vanzant & Schmelzer, 2011). Septic shock can be classified by acute circulatory failure as a result of massive vasodilation, increased capillary permeability and decreased vascular resistance in the body, causing refractory hypotension despite adequate fluid resuscitation. This leads to irreversible tissue ischaemia, end organ failure and ultimately, death (McClelland & Moxon, 2014; Sagy, Al-Qaqaa & Kim, 2013, Dellinger et al, 2013).

  • The Pros And Cons Of The Immune System

    The immune system is made up of a network of cells, tissues, and organs that work together to protect the body, and it defends the body from “foreign invaders.” Immunity can be divided in two three different defenses, and these are defined as first, second and third lines of defense. The first line of defense for the immune system is the primary defense against pathogens entering the body from the surface in order to prevent the start of disease and infection. Some examples of the first line of defense is the skin, protecting the external boundaries of the body, and the mucous membranes, protecting the internal boundaries of the body. Although the skin and mucous membranes work on the internal and external boundaries, they both release chemicals

    What is Multiple Sclerosis? Ms is an Autoimmune disorder. When the disorder progresses the nerves will be damaged and so the damaged is caused by inflammation. Another thing is the cells that were protected by a layer will be damaged as well. So when you have the damaged cell this will lead to the brain and the spinal cord. So that is what MS is.

    According to National Multiple Sclerosis Society, Multiple Sclerosis (MS) is an unpredictable, often disabling disease of the central nervous system (CNS) that disrupts the flow of information within the brain, and between the brain and body. The central nervous system (CNS) comprises of the brain and the spinal cord. CNS is coated and protected by myelin sheath that is made of fatty tissues (Slomski, 2005). The inflammation and damage of the myelin sheath causing it to form a scar (sclerosis). This results in a number of physical and mental symptoms, including weakness, loss of coordination, and loss of speech and vision. The way the disease affect people is always different; some people experience only a single attack and recover quickly, while others condition degenerate over time (Wexler, 2013). Hence, the diagnosis of MS is mostly done by eliminating the symptoms of other diseases. Multiple sclerosis (MS) affects both men and women, but generally, it is more common in women more than men. The disease is most usually diagnosed between ages 20 and 40, however, it can occur at any age. Someone with a family history of the disease is more likely to suffer from it. Although MS is not

    ... resulting impairment to the CNS. The first group of mice exhibited a pattern of CNS inflammation that resembled that of the most common subtype of MS, RRMS, with lesions filled with macrophages, a type of immune defender cell. The second group of mice displayed inflammation deep in the CNS tissues and in the optic nerve with lesions filled with neutrophils, another type of immune cell. Both groups of mice were given antibody drugs similar to drugs being developed against MS in humans. The effects were observed over time and results showed that some of the drugs inhibited disease in the first group of mice but did not inhibit disease in the second group. Thus, as Mark Kroenke (2008), the study’s first author and a Ph.D. student in immunology at U-M stated, "That's our proof that these really are different mechanisms of disease" (Kroenke et al., 2008).

    Multiple Sclerosis is a nervous system disease that affects the spinal cord and the brain by damaging the myelin sheaths that protects nerve cells. Destroyed myelin prevents messages from communicating and sending properly from the brain, through the spinal cord, to internal body parts. In the United States, more than 350,000 people are diagnosed with this disease. Anyone can get this disease, but it is more common among Caucasian women. MS symptoms begin between the ages 20-40 and are caused by nerve lesions being present in multiple areas of the Central Nervous System, symptoms differ on the lesion’s location.

  • Gingivitis Essay

    The inflammatory response is a nonspecific response to cellular injury and bacterial invasion. Inflammation is the primary defense in early gingivitis. Biofilm can initiate an inflammatory response if it is left undisturbed for as little as seventy two hours. Redness and swelling are two of the cardinal signs of inflammation and can be observed clinically in gingivitis. Histamine is released by mast cells and responsible for the redness and swelling of tissues. Histamine causes both an increase in vascularity and permeability of blood vessels at the site of injury. Swelling may occur in response to the accumulation of fluid at a specific site. The inflammatory response includes cellular components of the immune system polymorphonuclear leukocytes and macrophages. Polymorphonuclear leukocytes are crucial to the cellular immune response. Polyporphonuclear leukocytes are the first cells that arrive at an inflammatory site. Polymorphonuclear leukocytes arrive at the site via chemotaxis, and begin to phagocytize bacteria. As the disease continues and the inflammatory reaction is not strong enough to subside the bacterial infection the immune response is further

  • Acute Inflammation

    Inflammation which is part of the innate immune system is a process by which the body reacts to injury protecting it from infection and foreign substances with the help of the body’s white blood cells “Inflammation can be defined as the body’s local vascular and cellular response to injury caused by factors that invade and injure the body from the outside (exogenous factors) or factors within the body that result in cellular or tissue injury (endogenous) factors” (Battle, 2009, P 238). Factors such as bacteria, viruses, burns, frostbite, chemical irritants, immune reactions and physical injury are examples of factors that can cause inflammation through different mechanisms. It is a protective mechanism with rapid response that neutralizes or destroys agents that causes injury and creates a barrier that limit the injury and prevents its spread to normal tissues (Battle, 2009). Also, it has elements that removes debris and heals the wound generated by the injury. It can be divided into acute and chronic inflammation.

With no identifiable cause and a cure yet to be discovered, emphasis must be placed on advancing treatments and therapies. Although its pathogenesis is not completely understood, researchers are well aware that the immune response during MS revolves around inflammatory mediators called cytokines. Over the last few decades, substantial progress has been achieved in MS research and knowledge of cytokines in MS has considerably increased, allowing for the development of numerous drugs, including the successful Glatiramer
