Anti-inflammatory and Macrophage Inhibitory Potential of Picrorhiza kurroa in experimental models of inflammation.
ABSTRACT
The rhizome of Picrorhiza kurroa Royle ex Benth, is widely used for the treatment of various inflammatory conditions. In the present study, we have evaluated the anti-inflammatory and anti-granuloma activity of Picrorhiza kurroa rhizome extract (PKRE) against carrageenan-induced paw edema, cotton pellet implantation induced granuloma formation and Complete Freund 's Adjuvant (CFA) induced stimulation of peritoneal macrophages in experimental rats. The anti-inflammatory activity was grossly observed by determining the efficacy to inhibit the increased paw edema volume while the anti-granuloma activity was evaluated

In chronic inflammatory and granulomatous conditions, macrophage dysfunction plays a central role in progression and maintenance of disease like in case of rheumatoid arthritis where persistent antigen stimulation leads to accumulation of macrophages in the inflamed synovial membrane and at the cartilage-pannus junction [2]. This is evident by elevated levels of macrophage-derived pro-inflammatory cytokines such as TNF-α, IL-1β, IL-6 and inflammatory mediators such as COX-2 which has a key role in the maintenance of inflammation by regulating the levels of prostaglandins [3, 4].
Non-steroidal anti-inflammatory drugs (NSAIDs) and glucocorticoids supplemented with biologics are the conventional drug options for the treatment of chronic inflammation [5]. In contrast to their efficiency in improving disease conditions, chronic and long-term use of these drugs may lead to serious adverse effects such as gastric ulceration, bleeding and emergence of opportunistic infection due to immunosupression. In US, more than 16,000 deaths per year have been reported due to gastric ulcers and gastrointestinal bleeding associated with prolonged use of NSAIDs in arthritic patients [6]. Due to high cost and adverse events associated with conventional treatment, more than 70% of patients with rheumatoid arthritis rely on complementary and alternative medicine with or without conventional medicine [7].
Picrorhiza kurroa Royle ex Benth. (Scrophulariaceae) is a small perennial herb,
After the Roaring 20s an Economic Disaster struck which is well known as the Great Depression. This made struggles for thousands of people and put them out of work , money, and at the very least food. All though the Great Depression was rarely mentioned in Harper Lee’s, To Kill a Mockingbird, there are multiple instances stating economic trouble throughout the novel. A tumultuous event such as the Great Depression exacerbated tensions in the novel much like socio economic divides influences conflicts today; this is revealed through the analysis of events in the novel as well as present-day issues.
Rheumatoid arthritis is characterized by excessive inflammation, particularly in the joints leading to irreversible damage (Contreras-Yáñez, Ponce De León, Cabiedes, Rull-Gabayet, and Pascual-Ramos, 2010). Pain and joint damage leads to limited mobility, decreased function and a reduced quality of life (Elliot, 2008). TNF blockers provide significant improvement in patient outcomes “by reducing pain,
Rheumatoid arthritis (RA) is a systemic autoimmune disease that occurs when the body’s immune system attacks the tissue that lines the inside of the joints (synovium). Over time cartilage and bone within the joint is destroyed and the joint spacing between bones become smaller. According to the text Understanding Pathophysiology by Huether and McCance cartilage damage in RA is the result of three processes: (1) neutrophils and other cells in the synovial fluid become activated, degrading the surface layer of articular cartilage; (2) cytokines, particularly tumor necrosis factor alpha (TNF-α), stimulate syntheses of preinflammatory compounds, including interleukin-1 (IL-1), interleukin-6 (IL-6), and interleukin-8 (IL-8), and cause the chondrocytes
Gothic Literature Gothic elements are what identify pieces of literature as “gothic”. Gothic elements help create a mood of mystery, fear, and danger. Grotesqueness, the supernatural, and the presence of monsters are gothic elements that are prevalent in various short stories and in the novel, Miss Peregrine’s Home For Peculiar Children by Ransom Riggs. Grotesqueness is a gothic element that is present in the short story “Black Cat” by Edgar Allen Poe and in Miss Peregrine’s Home For Peculiar Children by Ransom Riggs.
The pathophysiology of osteoarthritis is a complex mechanism that involves chondrocytes and synoviocytes each playing a role in joint degeneration (25). The initial stages of the disease are characterized by inflammation of the synovial membrane, this process is also known as synovitis, followed by the loss of the cartilage surface (25). Although the exact reason for the cause of inflammation is unclear, certain intracellular mechanisms that lead to the up-regulation of pro-inflammatory cytokines and increased oxidative stress in the cells have known to recruit macrophages and lymphocytes into the synovium. This in turn leads to an increase in the production of pro-inflammatory cytokines and degradative enzymes that can
Rheumatoid arthritis (RA) is an autoimmune disease that affects the cartilage in one 's joints, it is not curable, it can not be stopped, only the pain itself can be lessened. In an average person’s body, the immune system has one job; to attack foreign substances that may enter the body. With the 1.5 million people in the United States that have been diagnosed with rheumatoid arthritis, their bodies are “tricked” or mislead into thinking that the cartilage within their joints is what is foreign. Once their immune system attacks the joints, it causes inflammation within, which then in turn leads to the synovium (lining of the joints) tissue to thicken. The synovium makes a fluid that acts as a lubricant to the joints and helps everything move freely. Once that fluid is gone, swelling and pain is experienced next. After awhile, the cartilage within the joints begins to disintegrate and will eventually cripple the individual. Along with knowing exactly what RA is, by the end of this paper you will know signs and symptoms within the oral cavity and systemically, and you’ll be familiar with how nutrition is related to the progression of this disease.
Rheumatoid arthritis(RA) is a typical, chronic autoimmune disease that primarily affects the joints, ultimately leading to synovitis that often develops into cartilage and bone erosion, apart from which, extra-articular features are presented, including sub-cutaneous nodules, vasculitis and pulmonary fibrosis, particularly in severer cases. Animal models of RA have proven to be useful tools for pre-clinical reasearch as well as for the study of pathogenesis due to the fact that animal
Rheumatoid arthritis is a disease that affects mostly joints, but can also spread to or affect vital organs such as the eyes, lungs, heart, and others. The disease is treatable to a degree, and if caught in early stages it can be easy to reduce inflammation and swelling in the afflicted areas. After reading this paper one should expect to better understand the symptoms of rheumatoid arthritis, causes of the disease, possible treatments, and ways to help prevent it. Nearly one and a half million (1,500,000) people in the United States are affected by rheumatoid arthritis, and three times as many women have the disease as men.
In recent years, the healthcare industry has seen a significant shift with a lot of new innovations and a number of target studies done on various topics. In particular, there has been an increased focus on understanding the inflammation and its role & relationship to chronic diseases. In this post, we are going to understand the inflammation and its role in general health & chronic diseases in little more detail.
Rheumatoid Arthritis (RA) is a common autoimmune disease. The chronic inflammation they induced lead to severe joint swelling and damage2. It is more likely to strike on aged people and females3. In Australia, 400,000 people are suffering from it with different extent3-4. The mechanisms of the disease are well-studied. The synovium is the primary target of the immune system for RA patients. With white blood cells migrated in, the synovium membrane becomes thick and inflamed, which leads to undesired tissue growth3. Various chemical substances are released from the inflamed site and starts affecting surrounding tissues, such as cartilages and ligaments. In severe cases, they might even result in whole-body disorder2-4.
Even though she was a bad queen, she was the queen of egypt. In the beginning, everyone looked up to her, but towards the end, no one could trust her. They didn’t trust her because she thought it was always gonna be about her. For example, towards the end, she got in a fight with Rome and that led to Rome taking over. Cleopatra was bad, but equally good. She was born in 69 BC and died in 30 BC. Through her lifetime, she fulfilled many roles. Such as, Queen, Wife, Mom, Girlfriend, and more. Some people saw her as being the most powerful ruler in Egypt, but some saw her as being the most evil woman who lived. Since Cleopatra was the last ruler, she lived in the New Kingdom. Cleopatra ruled for more than 200 years after her brother and Father’s death. Cleopatra had a very sudden death. She poisoned herself. She didn’t want to get captured, so she poisoned herself by getting a snakebite.
The human body’s immune system provides protection from foreign invaders. Inflammation is one of our body’s line of defense to get rid of infection and prevent disease. In rheumatoid arthritis, a deluded immune system may unintentionally attack the joints through uncontrolled inflammation, which can lead to bone, cartilage and joint erosion. “Rheumatoid arthritis occurs when the inflammatory response of the joint synovial membrane and periarticular tissues is conveyed by influx and activation of immune cells and release of inflammatory mediators such as chemokines and cytokines, resulting in tissue destruction and dysfunction” (Costa VV, Amaral FA and et al. 2015). Although the exact etiology of R.A is unknown, biological and environmental factors can contribute to the disease. Treatment goals are to reduce pain, improve function, and prevent further
During pregnancy, there are elevated levels of anti-inflammatory mediators such as IL-10, and lowered levels of pro-inflammatory cytokines such as IL-1β and TNF-α (Wang et al., 1996). Excess prostaglandin F2 (Norwitz et al., 1992a) and macrophage-associated products such as pro-inflammatory cytokine TNF- (Norwitz et al., 1992b) are released when the foetus is fully matured. However, early expulsion of the foetus can be a result of turned on pro-inflammatory cytokine production due to the presence of bacterial products (Nayak et al., 2012).
One of the reasons I chose to do this paper on osteoarthritis is merely because I can be one of the victims of this disease as a result of my family history connected with the disease. Both my father and my grandfather have osteoarthritis. They always complain about their knee pain. My father was informed that since there is no further treatment for the disease, he could only take pain-relieving medicines such as Tylenols and Acetaminophen. Thus, knowing the cause, symptoms, and remedies for the illness is very important so I could learn what I have to do in defeating the disease. Let me first define arthritis. The National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS, 2015) define arthritis as the inflammation of the tissue lining the joints (NIAMS, 2015, Para. 7). According to the center, patients with osteoarthritis have signs of inflammation that include redness, heat, pain, and swelling (NIAMS, 2015. Para.1). There are different kinds of arthritis. It includes Rheumatoid arthritis, Osteoarthritis, and Psoriatic arthritis. Given the time and resources, the focus of this paper is limited to osteoarthritis that is the inflammation of joints only.
Recently, GA has been found in several studies to have anti-inflammatory and antioxidative properties making it an apoptosis scavenger [12, 15]. Furth-ermore, previous in vitro studies showed that GA dose dependently scavenged generated superoxide radicals [18]. In this study concomitant treatment with GA significantly reduced the inflammatory and oxidative stress induced by the administration of intraperitoneal adenine. These include a reduction in GSH, SOD, catalase and TAC. It also significantly reduced NGAL, NAG and cystatin C, the biomarkers of acute kidney injury [33, 34]
