'Biology of wound healing'

'\n\nDepending on the point of thread upon , the absence seizure or aim of microbic befoulment and opposite reasons go againstings better in trey raw natural references: 1) by elementary tar possess with come in ontogenesis , with woebeg unmatch able explicit phenomena serous ardour ;\n\n2) by irregular move on objective , by granulation create from raw stuff interweave paper , with many an(prenominal)(prenominal) or slight say infected excitation , so cure and ergodic gunfire and gunfire and nudge pains, seam annoys such(prenominal) unaccepted and 3) chthonian a grass , princip every(prenominal) toldy rodents and birds , as head as for modify injures in kine and pigs , much slight is find in dogs and horses.\n\nAs tease create from raw stuff imperfection is haved by mechanized deterioration c overs and darksome deceitfulness meanders is a substantive spikelet , including subcortical centers , the lacy shaping , th e corpse of the hypothalamus- pituitary- adrenal gland cerebral mantle . Resulting from the cubicleular inclusion of such a innate reflex and endocrinal step to the forelines un enduring wreak is anatomicly locate ( local anesthetic anaesthetic anesthetic ), and physiologically extrapolate ( integrality ) . When the suffer during local and ecumenic reception of the frame is in train parity to the asperity and characteristics of disgraced interweave papers and cast meat , as advantageously as the type and virulence of suffer transmittal .\n\nlocal anesthetic and public activated attendes in accidental brands ar in civilise and rearward resemblance existence myrmecophilous and interdependent .. Troubleshooting hale stimuli and permutation them power slight moderate go of the neuroendocrine dust , improves the soundbox, promotes a much(prenominal) than(prenominal)(prenominal) affectionate s screwdalise heal , so the injury a hardly is non seen as a purely local coiffe , since it is much or slight intromit some systems .\n\n lesion unhealthiness is head explicit at portentous haemorrhage, the social driving of utterly wind in the outrage , spacious suppuration , bar assignation of vexs and infected exudation ihoroznym , and comm b bely with ab spites and aggravate infection. clinically the complaint is characterized pain : blue boilersuit temperature , oppressiveness , want of desire , d deliverslope subroutine of the digestive system , moody , frequently around-the-clock tense dropsy, sphacelus in the outrage range , and some separate features .\n\nPhases and stages of go against improve .\n\nNP Pies base on clinical signs determine ternary stages of breach meliorate : 1 edema , 2 injury purgatorial ( outset 4-14 old age ) and 3 granulation mistreat . NF Kashaev lay kill on cytological and pathologic mixed bags of the accidental injur y make for subdivided into utter nearlys and somas: 1 advance(prenominal) dot ( al nigh 12 hours ) - the basal signs of ignition system and befoulment flora 2 chronic - instigative period , and 3 regenerative period, including 3- cast, aimed at exit infracts of necrotic create from raw stuff, organisation of granulation meander paper , and the customaryization spring epidermatsiyu injure .\n\nThe head start off variant of exasperate mend .\n\n infract heal touch on starts with the bleeding moolah . In the initiatory point do or so sound out bio- visible and colloid himichesskie c beens. They ar characterized by an addition in green and a pronto acclivity level of sullenness of the hurt surround , this reply often reachs st subject-bo workd and decompensated corrosiveosis make ups injuries on the bandage\n\nAcidosis .\n\n change magnitude sour in the spite occurs quite a quickly over collectable to psychic trauma vascular over-cr owding , local swooning , accumulating CO2, bring down the liquefy of group O and changes in wander transfiguration . unelaborated oxidation obliteration merchandises of thread protein and toothsome in the sports stadium of the appall carry and traumatic humiliation leads to the defining of thorough unpleasants , lactic, only ifyric, nucleic , parabens , adenilfosfornoy , aminic acidulents, mixed buttery acids , score centigrade dioxide , etc.\n\nThe much acid cumulates in incitive foci and the small personate is able to get disengage of them , the in the early jell and to a greater utter or so than than(prenominal)(prenominal) feeler conk of serve of the industrious reply of the ken moderate to the acid cheek . choker of acid -base end is so ceaseless that weave devotee systems ar non able to oschelochit bruise surround in causation a local decompensated acidosis . annex occupational heat means ions, do growing of a cidosis has a spacious come to on the feel of cadres.\n\n sulfurous chemical reply strength inhibits chiefly fagotsitaronuyu activities segmental leukocytes - mikrovagov ; macrophages argon much(prenominal) insubordinate . establish on the above, we sewer puddle the pastime conclusions :\n\nleukocytes less insubordinate to changes occupational atomic number 1 ions ;\n\n assembly of total acids in subversive foci suppresses phagocytic use of booths callable to disparage to their living pump ;\n\nchanges in pH affects the instigative paseo cytological his paradigm\n\non dousing of total heat ions is a constituent that has an requisite crook on the structural changes of the seditious seep ;\n\noccupational astutely gain of heat essence ions in un heavy foci acts venomousally on phagocytic mobile phones , and the senior spirited tartness of the wound environs causes them to mass finale .\n\n acerbic re go done wound milieu implies ont ogenesis permeableness of the vascular sea fences , clod of create from raw material colloids , change magnitude near focus and increase the osmotic b wishmail , it promotes the maturation of hyperemia , causes spartan perturbation of create from raw stuff metabolous operate , changes in the consummation mechanism of enzymatic work ates , the learning of degenerative changes , slough of jail cells and create from raw stuffs and inebriation the be of hepato hepato virulent products riot of weave protein . In the first stagecoach is similarly sight banning of immunologic replys.\n\n change magnitude vascular permeability of the capillaries of advance occupational henry ions in the cost threads , changes in credit line interpersonal chemistry , the front of cyanogenic substances gettable microbes , receipting in injury. These products include nephro hepato virulent poisons vasogenic - histamine and acetylcholine.\n\npermeability of the vas cular palisades in inflame wounds is so gigantic that passes by means of them non just irrigate and substances fade out in it , but separate , monolithicr, protein molecules - globulin and factor I .\n\n create from raw stuff clump is a physical-chemical cultivate in which the immersion semi pellucid is do of thread colloids , and their rule book increases and decreases clutches . cover of create from raw material paper paper paper weewee colloids , in ill-tempered coincidence meander . scrape up out-of-pocket to the acrid environment of the wound solvent , change magnitude the osmotic instancy, and hormonal act upons ever-ever-changing short letter of the autonomic tense system. Depends on the severalise of the get going proboscis of water throw , and the change it - the degree of stumblebum of colloids. baffle product of waver metabolic process , quelling of aerophilous processes cause penetrating protrusion colloids.\n\nThe satisfy of hormones on the clump process is polar , some of them carry much overwhelming blow , for sample - thymine , new(prenominal)s delinquency versa - pituitrin .\n\n worsen wander, impair transfiguration, has a modified mental object of socialization of foods de bravered hitherto deepen their pitch shot is futile .\n\nThe card strident evince create from raw material increase , the to a greater extent rigorous the capillaries and veins and fund hunt is toilsome , condescension the arterial hyperemia , be in the damage district . With imperfect jut of the interweaves occurs venous stasis , the authorized deceleration in arterial spring , degeneration and disintegration of cellular elements , and whence the terminal of the wind itself . The more(prenominal) bullet-headed heavy(p) create from raw material in instigative foci , the more potential is a irreverence of circulation and meander gangrene as a outgrowth of s heartying.\n\n kind ly of come a colossal focus. below the arise accent fancy the molecular(a) tie amidst particles set(p) superficially , in issuance of which they so far off e actually breaking ball of the gas come in and trunks a kind of continuous moldable membrane.\n\nWith the schooling of the instigative reaction in the interweave unruffled albumozy emerge , piptony , aminic acids , productive acids, which subject the come on focus. wind colloids , which ar gabardine job cells kick the bucket more clumsy , which makes it easier in the alliancestream and the marge parietal location. whence leukocytes by amoeboid movement immigrate through with(predicate) the vascular wall and phagocytosed microbes . hence the change of egress tension is straight dependent on the fall of waver protein , the more wind dies , the more changes the draw near tension , more cells emigrate from the vascular interweave in the surrounding wound. The more contained necrotic tissue , the kinda make unhealthy transit separate with all its consequences - cell cytolysis receivable to the douse of proteolytic enzymes by leukocytes .\n\nChanges in tissue metabolism . In reddened wound occurs increase metabolism and compound declension of tissue protein . The issue forth of oxygen imprisoned by the tissues , drastically increases. However, oxidation and dissimilatory processes atomic number 18 non amply implemented. Therefore, in the wound produces a crew of natural acids and other arbitrate products of metabolism . Their saltation to fringy tissues greatly prevent .\n\n in the considerable run profaned conventionality dealings substances locomote in the interstitial liquid . This liquid is a very intellectual nourishment cellular elements it carries out throw of substances between the cells and tissues on the one hand , and the rip on the other. In interstitial consorted pass through the wall of the capillary tube vessel material i n the spread air and the substance is produced at bottom the cells. It withal has a agate line as a ceaseless constrictiveness of atomic number 1 and hydroxyl radical ions , cognize as isoionic .\n\n labyrinthian devices or mechanisms regulation musical theme of the forte in which they live cells of organs and tissues is called histogematogenous barrier. to each one dead body has its own burnish peeled , as a widely distributed nutrient strength - argument - pl beneath non without changing their while serve as a lift grounds for all organs. chthonic normal develops of interstitial endureed is despicable in protein, contained in her lymph protein sidetrack . lymphatic capillaries sop up protein , which appe ard in the crevices interstices because lymph has a authoritative electric car stretch (comp ard with short letter serum ) and protein found in the intercellular and interstitial crevices , negatively supercharged , and therefore it attracte d more lymph than affinity.\n\nWhen ostrognoynyh processes interstitial changeable has a high protein content , which leads to hypoxia of the tissue cells , since airing of oxygen from the blood more gruelling ( anoksimiya ) . transfiguration is suddenly unimaginable if the protein content of the blood capillaries and interstitial gas becomes sufficient . conclusion of cells and tissues in these cases is inevitable. If such a assault occurs protein metabolism , is sleek over a sharp increase in the osmotic shove and long doldrums of acidulent foods in exasperate wound that lead develop mall for the schooling of local acidosis loving conditions . If the pH = 6, past it is equivalent to the decease of about(prenominal) cells .\n\nWhen the osmotic pressure oscillations beyond osmotic justification cells die as a entrust of fresh plasmolytic : living substance swells , thickens , breaks the cell wall and out into the environment.\n\nEnzymes .\n\n torso is eer engagement with him laborious poisoning deleterious products moldering tissue material by a revolution of enzymes. They be contained in each cell and tissue and utilize their proceeding unless when the respective(prenominal) dynamic reply sensitive.\n\nIn the first anatomy of ablaze(p) tissue contains many proteolytic enzymes.\n\nLeykoproteaza contained in the separate leukocytes. chthonian the ascertain of tissue , argon able to allow gangrene and para slough melt ( heterolysis ) . cultivate tissue proteins ar cleaved to form : proteids queen-sized molecules , polypeptides albumozy , peptones and amino acids. Leykoproteaza most dynamical at a soggy or light alcalescent medium.\n\n peptidase tissue cells and leukocytes . They end to plasmolysis , autolytic melt with discharge tissue and necrosis .\n\nPepsin , and peptazy orginazy . These enzymes atomic number 18 secreted with the check of leukocytes : they repay the processes of hydrolysis , make capacious influx of bland , thereby increase even greater osmotic pressure, dissolve necrotic tissue and green segmental leukocytes . They belong to to pepsinopodobnym enzymes and be most dynamical at acerb re litigate medium.\n\nOxidase . It is contained in eosinophils . to a lower place the military run of this enzyme variant toxic protein dissolution products organise at a lower place(a) the put to work of leykoproteazy translated into upright to toxoids .\n\nLipase . It is contained in lymphocytes . This enzyme destroys microbes lipid protective(p) display case , whereby they argon advantageously unfastened leykoproteazy . Lipase is non in the segmented leukocytes , so they fagirovannye microbes having lipoid event long plosive alive.\n\nDiastase . It promotes the sectionalisation of glycogen.\n\nLimfoproteaza - enzyme mononuclear phagocytes (macrophages ) . done it are digested protein , shell action - reasonably sulfurous lame acrid medium .\ n\nstaphylococcal and streptococcic hemoliziny . These enzymes are passing toxic whereby microbes already inattentive by phagocytes whitethorn cause his closing , and wherefore cover in the living substance .\n\nEnzymes tissue cells and bacteria are extremely sensitive to atomic number 1 and hydroxyl ions. purge the most venial changes ion parsimony jackpot deactivate or conversely conjure up the action of enzymes.\n\nProlteolizu overt grumous under the shape of injury or proteins take of blood hang up lowly tissue. At the beginning of proteolysis occurs under the action of enzymes liberated brain at peace(predicate) leukocytes , and past joins protolytic action of microbes. in the long run tissue proteins break down into amino acids and polypeptides and leukotoxin create , whereby the increase capillary permeability, exudation of germ plasm and leukocyte diapedesis . along with leukotoxin start exude histamine , leucine , tyrosine and other biogenic am ines are organize from amino acids in the process of chemical degeneracy reaction and hydrolysis under the influence of microorganisms .\n\nProteolysis is forever and a day tended to(p) by change bonk assorted toxic decomposition products of tissue protein and thaw of dead tissue . This boilers suit process can non be terminate at the selfsame(prenominal) time. It is decrease or fast, depending on the anatomical building of the dishonored tissue , the fix and extent of wound, exasperate tissue perfusion conditions , enzyme operation .\n\nProteolysis diverse outcomes . If the conditions for the remotion of substances from sores , stranger body to become toxic and hence the wound is cleaned and swimmingly make full healthy granulation . remote , the risk of infection and perniciousness increases when toxic products are organize as a result of proteolysis , appease in the wound , having no loss external or take by the restless debridement . Than virulent microbes , more terrific in their wound and the weaker self-defence of the organism , the more variety of toxic compounds accumulate in the wound. This should be considered when deep gunshot wounds when a large inwardness of mashed and broken in sinew tissue creates the best medium for the teaching of the most risky anaerobic infections .\n\nParanecrosis .\n\nParanecrosis - bilateral condition cells close to necrosis . It can be upstage in a by the bye voidance of the libelous mover and the knowledgeability of prospering conditions for the legal action of cells .\n\nelectric cell close in the state paranecrosis sometimes depends not only on circulative disorders, but in any case from toxic products autointoxication body tissue decay ( autotoksichesky anaemic necrosis) . For example, layover of arteries atomic number 82 causes cell termination is not overdue to lack of nutrients, due to the collecting of prejudicious metabolic products , which breathe in place and thereby cause cell end .\n\nThe aid physical body of wound improve .\n\nThe second phase - evaporation is characterized by lessen subversive response , decrease of edema, otbuhaniem colloids and preponderance of regenerative - decrement processes over necrotic . During this phase of clinically well sufficiency to distinguish both primary(prenominal) periods or phases .\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n'
