The main outcome measures were the percent area of the wound compared to baseline area of the wound. As the wound decreased in size it is theoretically assumed that the wound is healing. The central concepts of the study were based on ultraviolet-C positive effects on wound healing in vitro. In vitro studies effects include; modification of growth factors, fibronectin release from fibroblast, epidermal cell proliferation, killing of pathogens, accelerated DNA synthesis, and antibiotic-resistant organisms.

Being ambushed by an abrasion on our skin whether it be a pimple, a scar, or something with greater depth such as malignant melanoma can cause quite the adrenaline rush. Diseases of the integumentary system are just as life threating but can be even more mind boggling than a disease occurring internally. For a person to actually see the change in their skin while taking steps to cure it on their own with home remedies and skin care treatments just to find out that the disease is beyond just a simple “break-out” or rash can cause other problems such as stress and insecurity. The integumentary system fights as a barrier to protect the skin and also excrete waste, diseases sometimes hinder this system from doing its main job; which is defending

The immune systems helps the body fight off the other parts of our bodies and harmful substances such as disease, infection or bacteria. Some strategies for ensuring a healthy immune system are: don’t smoke, move your body which mean exercise regularly, eat diet food such as fruit and vegetable, get a good night sleep and maintain your healthy weight. These strategies are a good way to start giving your immune system the upper hand.

Neutrophils start with the critical task of destroying and removing bacteria, foreign particles and any remaining damaged tissue. This phagocytic activity is crucial as bacterial imbalance within acute wounds causes the wound to stop healing. Neutrophils are attracted to the site of injury within 24 – 36 hours by pro-inflammatory cytokines including TGF- β. Neutrophils are one of the most abundant cells of the immune system and they are extremely active during the repair of cutaneous wounds. In general, the antimicrobial

Schizophrenia is a neurodevelopmental condition that has unclear etiology. Current research indicates that the condition is caused by numerous causes, including genetic predisposition and environmental factors. Genetics is indicated as the etiology for many individuals who develop the condition. However more research is indicated in order to understand how environmental factors contribute to the development of schizophrenia. Specifically, how factors such as infection influence the developing brain and whether or not an individual’s immune response adversely affects neurodevelopment.

The skin is the largest organ of the body, and consists of two layers the dermis and epidermis. The skin acts as a protective barrier against microbes and the elements; it also helps regulate body temperature, and permits the sensations of touch, heat, and cold. However, the skin can be compromised by injury, a burn is an injury that occurs to the flesh or skin, and can be caused by heat, electricity, chemicals, friction, or radiation. Burns vary in their severity from minor partial-thickness superficial burns to full thickness third and fourth degree burns. For the purpose of this paper I will be focusing on major burns (e.g. full thickness third and fourth degree burns).

The molecules released in this time cause vascular dilation and smooth muscle contraction that can be observed in the ‘wheal and flare’ response. The wheal and flare response is the name given to the reaction of the skin following an allergic response. The ‘wheal’ describes the inflamed, raised area and the ‘flare’ referring to the portion of red skin surrounding the wheal. The primary molecules released in the immediate hypersensitivity reaction are proteases and histamines (vasoactive amines) as well as lipid

This methodology was able to successfully label ~90% of Mcpt5-EYFP cells in the dermis and did not alter mast cell degranulation. Similar to the studies detailed above40,59, intravital imaging of mast cell degranulation highlighted the extravasation of vascular dyes. Interestingly, the vascular leakage occurred before any detectable release of labelled mast cell granules, probably mediated by histamine release after activation. Post-degranulation, few of the mast granules appeared to be transported further into the tissue, akin to a previous report60 where intact mast cell granules travelled to draining lymph nodes. Fluorescent avidin based labelling of mast cells in the IL-10 GFP reporter strain showed the presence of predominantly Av.SRho+GFP- mast cells under homeostasis. Post-challenge, mast cells were identified as a source of IL-10 within the activated tissue with more than 50% of avidin labelled mast cells expressing GFP24. However, within 2 days, other immune cells contributed to the production of IL-10 with mast cells only constituting approximately 10-15% of GFP+ cells within the inflamed tissue. The presence of mast cells and IL-10 was intimately linked to the suppression of inflammation during severe contact hypersensitivity.

A critical function of inflammation is to deliver neutrophils to the site of insult so the initiation of leukocyte activation can occur. The migration of neutrophils from the intravascular to extravascular space requires a

Fish undergoing internal or external challenges to their state of health mount a vigorous response including activation of both the innate and acquired immune system [1]. The innate immune system which covers those aspects of the host defense mechanisms not dependent on specific response, not only stimulate leukocyte activity but also affects many aspects of the host metabolic processes including immunological response to inflammatory stimuli by activation of phagocytes, and by altered levels of plasma proteins (AAPs). These changes in the plasma proteins have drawn attention to the importance of the innate immune response in fish. Acute phase proteins (APPs) are a large group of biochemically and functionally unrelated proteins whose plasma

The human skin is the largest organ within the human body (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3535073/). The surface of the skin is formed by cross-linked cell envelopes and specialized lipid molecules creating the structure of the epidermis (NCBI). The human skin is slightly acidic (pH 5-6) which is beneficial for resident flora (Lambers). The human skin acts as a barrier which is one of the first lines of defense against harmful microbes, most commonly specialized immune cells help to fight off invasive organisms. (NIH). Levels of specific microbes can fluctuate a great deal up and down but normally stay relatively constant due to the competition with other organisms on/in the skin (Ppt).

Since the universe evolved, there have been both 'good' bacteria (i.e. aid in digestion) and 'bad' bacteria, often causing infections, disease, and even death in mammals. Therefore, unwanted bacteria being ingested, inhaled, or penetrating a physical barrier can cause multiple issues for that animal. Once the bacteria have penetrated the body's first line of defenses, like entering through a cut for example, there are multiple responses from the body to repel this foreign organism and signal that there is an issue. From this, the rest of the body can work to destroy the bacteria with the innate and adaptive immune response while it also develops memory and defenses against any future invasions of that species.

Inflammation is “a condition in which a part of your body becomes red, swollen, and painful.” The two most common causes of inflammation are injury and illness, which the body responds to by producing C-reactive protein (CRP). By using Cue’s Sample Wand to collect a drop of blood, individuals can measure what many experts believe is the best overall marker of inflammation.

An understanding of the structure of the integumentary system will assist in understanding how burn injuries affect the entire human body. The skin preforms anatomical and physiological functions which are essential to life. Damage to this system has the potential to cause irreversible chain reactions and wide spread systemic collapse that can lead to death. DermNet NZ (2006)
