A skin pigment (substance that gives the skin its color). Dark-skinned people have more melanin than light- skinned people. Melanin also acts as a sunscreen and protects the skin from ultraviolet light.
Melanin is produced by cells called melanocytes. It provides some protection again skin damage from the sun, and the melanocytes increase their production of melanin in response to sun exposure. Freckles, which occur in people of all races, are small, concentrated areas of increased melanin production.
Dark color protects against disease, and not from the sun
Australian scientists believe that dark skin is better protected than white reflecting infectious bacteria and fungus infection. This may explain why dark skin developed in humans and animals living in tropical regions of Earth. The results of this study, for authorship biologist James Mackintosh, printed in the journal Theoretical Biology. According to newscientist.com if this hypothesis is true, then the evolutionary development of the color staining of the skin should correlate with the temperature and humidity higher than latitude and sensitivity to the flow of sunlight. Popular theory on why more dark skinned tropical prevailed in some areas than in others bright, is that the additional melanin in darker skin protects against skin cancer and tanning caused by ultraviolet radiation. But while some parts of the body, which hardly ever exposed to sunlight, such as genital organs, protective function of Melanin crotch and handkerchiefs alleys, also reserved the skin cells of melanin. Animals type gorillas have dark skin even though they are constantly covered with fur and dzhungly tropical foliage. In addition, it turned out that melanin is not enough sunscreen to protect the skin from sun... protective function of Melanin. Dzheyms Mackintosh suggested that melaninovaya skin has antiseptic properties to form a protective shell of the invasion of pathogenic microorganisms and bacteria, the body's defense against disease. In mammals melanin contains internal bubbles, called melanosomes. It is anticipated that melanosomes may have features like lizosom the immune system, which include invading microorganisms and enzymes used to destroy them. In laboratory studies, melanosomes human skin can slow the development of microorganisms. Melanine is a sticky molecule. Bacteria and fungi attach to a molecule such as flies to protective function of Melanin, and it stops them from spreading throughout the body. What is the protective function of Melanin.

Melanin is a special pigment that gives the skin and hair its natural color. It makes the skin tanned, but also produces unwanted freckles, birthmarks and other colored marks on the body.What is the protective function of Melanin - More Details
With humans melanin forms in special sea-star shaped cells called melanocytes in the basal layer of epidermis and then transforms into granules where pigments are combined with protein. Melanocytes inject melanin grains into the cells of the upper skin layer (cortical layer of the hair and the iris of the eye) and determine their color.What is the protective function of Melanin - Doctors view
Doctors from time to time state that tea, coffee, chocolate and cacao are harmful for our health. However, it is no good to give up these products once and for all as they contain melanin that is essential for the human organism. Also prunes, bilberry or dark grapes are good protection against cancer, sunburns and influence of radiation.Also, protein, called attractin, which are known to regulate the degree melanin and immunity in humans shows that more black people are less susceptible to skin disease than people with bright skin. During the Vietnam War, for example, American soldiers of different nationalities were sent in the Mekong Delta. White soldiers were three times more prone to skin diseases caused by streptococcal pyogenes, compared with the black soldiers. In the northern parts of the Earth's polar and temperate zones, is better suited Bright skin because it absorbs more sunlight, it leaves at the expense of a lack of vitamin D in the human body. A number of such pathogens as bacteria and fungi in the tropics, in these areas there is so protective functions melanin in such quantities as to the black people, for this region is not required... it's protective function of Melanin.
The ability of melanin to protect against microbial host objection is relevant to the antimicrobial therapy, as well as some clinical efficacies of antimicrobial agents is complemented by the host immune defense. Melanin has been shown to interfere in numerous defense mechanisms. Melanized C. neoformans yeast cells demonstrated an increase in resistance phagocytosis vitro and in living organism. In macrophage cell type, in phagocytic index melanized Paracoccidioides brasiliensis yeast cells was half that at nonmelanized cells. Since melanins charged polymers, their presence in the cell wall C. neoformans can change the fungal cell surface charge, and this could lead to inhibition of phagocytosis. Melanization increased cellular negative charge from 3 to 33% in nine different strains embodied and by 86% in acapsular strain. In addition to reducing consumption, melanization protects C. neoformans against killing macrophages. Moreover, the production of melanin in Fonsecaea pedrosoi, Sporothrix schenckii, and Exophiala spp. increases the resistance of the assassination of phagocytic cells. In melanin pigment C. neoformans yeast cells can produce complex immunomodulatory effects that contribute to virulence to a host of changes in cytokine / chemokine response. In particular, melanized yeast as a result of higher levels of interleukin-4 and monocyte chemoattractant protein 1 and the increase in the number of leukocytes light early after infection. F. melanin also activates pedrosoi humoral and cellular responses and protective function of Melanin.

Heylity-red edging inflammation, mucous membranes and skin, lips are fairly common pathology in children. In different ages reaction to the same external stimuli can be varied depending on the lie of morphological and functional properties of tissue maturity.Cover fabric lips represented sister origin and morphology, but different reaction to external stimuli and ways to maintain homeostasis-skin, red edging and mucous membrane.
Leather person (including the Bay) opened many volatile effects of external factors, such as drying, moisture, temperature fluctuations, sunlight, etc. Physiological conditions for the oral mucosa are constant humidity and heat: temperature about 37 °.
To ensure tissue homeostasis cover their lips and adequate response to the external environment is very important that the rest were somknuty lips, a stereotype of links between the lips happened transition from the red edge in the mucous shell (zone Klein).
If the child breathes Mouth, no eyes or lips brings them correctly so that some of the mucosa proves how protective function of Melanin turns, it leads to the development of the "weather" heylita.
Defensive function of the skin and oral mucosa is carried out by protective function of Melanin barrier protecting be connective tissue of the external environment impacts, as well as from surface robes: a What is the protective function of Melanin, the oral mucosa, mucus and saliva.
Protective properties epithelium red lips and edging especially oral mucosa lower. This is due to a lack of hydration layer of cells, a lack of pigment that protects from the sun. However, oral cavity, in particular envelope mucous, saliva uvlazhneny well, with a high degree of healthy people by bakteritsidnosti contained therein gumoralnyh factors immunity. What is the protective function of Melanin.
Sleeves oral mucosal has protective properties of peristalsis (AI Rybakov, Granin AV 1967), behind the movement and breeding mucus accumulations, and microbial alien substances. In the oral cavity as a peculiar compensation lower than that of the skin, protective barrier properties epithelium developed his ability to phagocytosis and the high regeneration ability. Therefore, the use in the treatment of previously popular Paint (methylene blue, etc.) resulted in the skin lips long they persist, and the mucous coat of lip rapidly disappearing because of the active phagocytosis. Healing and epithelization trauma surfaces elements vysypany happening in the mucous casing faster than on the skin, despite the lower quality of the protective barrier...

In increasing age (4-12 years) protective functions epitelialnogo cover is not yet fully separated, but already operate more is the protective function of Melanin.
In heylitov pathogenesis, as well as the maintenance of homeostasis and is important group of the "exchange" the functions of the skin and oral mucosa, particularly high activity skin and mucosa absorption of various substances from the surface. In childhood, this ability is very high. Therefore, in children is especially dangerous use of drugs and ointments containing hormones and the biologically active substances. This is a recipe to rethink tactics heylitov treatment in childhood, unlike adult treatments based on the use of hormonal therapy.
