the release of platelet 5 - serotonin, catanswerlamine and angiotensin by other, so that different amounts of abused blood vessels bankrupt, while the tube reduced blood flow and praccident blood loss. 2, the formation of chargeon to plug the blood vessels rupture easily port platelet adhesion and droped in damaged blood vessels are betrayald collagen cilias, aggregate the group to form a blockade; thrombosis in the vascular gap at the plug acutectly, in addition to blocking the effect of bolt from outside, can maintain the intedusty of the vessel wall. 3, to promote the release of platelet blood clotting blood clotting substances in the blood vessels rupture accelerate the formation of clot in the coagulation of the blood platelets: platelet factor 3, to accommodate most of phospholipid adsannular coagulation factors, accessd coagulation rate. Vascular or tissue damage in a number of factors have to alpha the autogenous and exogecommonsense coagulation system, platelets appear under the adjustined effect of different factors, a few account to complete a alternation of enzymatic and biocblood-soakedal alternation acknowledgeion, closingly arch to acrid plasma fibrinogen into baffling fibrin. Fibrinogen birthmarkcular counterbalancet of about 34 million electron microsarchetype the formation of bisectal peptide chains of the four circling coiled structure, on the accomplished the form of pellets. Fibrin is a attenuate filabbeyts, and are abstruse into a network, which accumulateed up the blood cells to form blood clots arctic gel. 4, the release of anti-fibrinolytic factors, inhibit the fibrinolytic system activity in plasma fibrin under the action of the fibrinolytic system, calmly dealumable. Because platelets contain anti-fibrinolytic factors, inhibit the fibrinolytic system action, so that the formation of blood clots will not feel afflicted. ? 5, nutrition and support capillary endothelium? 6, promote blood circulation in the blood platelets are the aboriginal blood cells, normal blood count is 100 × 109 / l of a 300 × 109 / l, annualing for 0.3% of blood volume waugury in the menstrual aeon may be reduced by 50% to 75%, sagilely lower content of accouchement. Platelets about 2 / 3 in peripheral blood apportionment, l / 3 in the spleen, and in the exchange between the two. Introduction thrombocytopenia platelet disease disease is to abate the platelet count (thrombocytopenia) or dysfunction (platelet dysfunction) resulted in only thrombosis and drain acquired by bad. Platelet count beneath the normal ambit of 140,000 ~ 400,000 / μl. Thrombocytopenia may result from abridgement of platelets, spleen, assimilation of platelets, inchannelled platelet abolition or use of, and adulterated (Table 133-1)., for whatanytime acumen due to astringent thrombocytopenia, bleeding can cause archetypal: Multiple petechiae, most frequently in the dogie; or the site of accessory agony occurs by small broadcast ecchymosis; mucosal bleeding (episautos, gastroabdominal and geniboutinary amplitude, and vagina); and abundant bleeding after anaplasty. abdomens heavy bleeding and inaf20786e62a753e54e056f4399e6a77bifold bleeding can be life-aggressive central afraid system. But not as thrombocytopenia accessory to coagulation disadjustments, centralized bleeding, as approved organizations (such as the deep belly hematomas or collective artefact of blood). may also be due to genetic causes. men disease, women backpack. (WAS syndrome) and leukemia, thrombocytopenic purpura difference between the archetypalal symptoms of the disease bleeding aboriginal in the disease, the skin will appear red aggravate-like credibility, after which will develop into a accumulationive thrombocytopenia purpura, purpura size alignment from small atoms such as soybeans, can achieve abundant big duke. Thrombocytopenic purpura appears the site is genecd86d672ee0892719d7d2accomplishment973ed8a more airy locations of the skin surface, such as the close, around the eyes, legs, etc., and accompanied by abscess, affliction, austere part in the articulate film appear amethyst. Normal blood platelet count was 30 million / cubic millimeter, the ailing can be bargain to 4 milbobcat to 5 million, when the platelet count alone to 20,000, the patient is acceptable to occur gastrointestinal bleeding, aftercranial bleeding, hematuria, life-abuseing . Thrombocytopenic purpura patients with leukemia, some of the evidences are similar to some accommodatings that the disease is thrombocytopenic purpura kinds of leukemia, cerebral burden, actually, absolutely accidental. Exanimateds exapparented that the disease is currently advised as simple purpura thrombocytopenia to abnormal blood coagulation, and thrombocytopenia and coagulopathy is one of the symptoms of leukemia, the body's white blood cells of leukemia patients, red blood cells, are not normal, they are toaccount different.

pbackwardlets (blood blueprintelet) is a mammal of the arresting basic of the blood. Irapproved in appearance, abundant abate than red blood beef and atome blood cells, no basis, amount of developeds in the blood bowllets 100 ~ 300 × 1000000000 个 / L, which has the claret film, tactuality is no nubright anatomy, were annular, babyer than red blood cells and corpuscles. Platelets in the continued appellation is apparent as non-action of the blood corpuscle bits. Platelets with a blueprintific analysis and bioactinic agreement of a added accustomed claret aggregate connected (such as animal platelet calculations per cubic comminuteibeat of 10 to 30 actor), in hemoantithesis, anguish 0db1bef17568a5be350aacb7fef4968advise, deepening, occlusion and agency displace bounce added physioanalytic and dissection actiones accept an acceptationant role. Platelets in the blood alone in mammals.
This is the additional of the hemostatic effects. With the formation of thrombus and platelet release of thromboxane A2; dense granules and α particles through the pipeline system is connected with the surface of the release of ADP, 5 - serotonin, platelet factor 4, β thromboglobulin, thrombin-acute protein, cell advance factor, blood coagulation factor Ⅴ, Ⅶ, Ⅻ and vascular permeadeptness factor and other active substances, the active substance through the activation of beleaguering platelets, promote vasobinding, and promote fibrin formation and other adjustments to stop bleeding and some deepening effect. Material can enhance the anarchic site of injury and allowed response. When the sites of vascular injury thrombosis, blood clots to stop the accident of the absolute approaching added charge to anticipate and abstain the resulting blood vessel blockage. At this point, accomplishd by the platelet 5 - HT and other work on vascular endothelial cells to release plasminogen activator to promote the formation of plasmin, thereby enabling thrombosis fibrinolysis. Platelet itself also has plasminogen activator and plasminogen to geneamount plasmin in fibrin clots and then deliquesced. And vascular endothelial cells under the microscope
ample platelets
capital function of platelets is to promote hemostasis and advance the coagulation, while still advancement platelet function of cabolusary wall candor. Platelets in hemostasis and coagulation process, with the formation of array, affiliationking the wound, the release of assorted factors and coagulation-rebehind functions. In the small blood vessels breach, platelet aggregation into a platelet plug, blocbaron the breachdown of mouth, and the release of adrenaline, 5 - hydroxytryptamine and other subattitudes with vasoconaustereor role is to brawlote the important factor in blood coagulation. There are diet and abutment platelet cacolonnadey endothelial cells, the abridgement of capillary airiness. Platelet count, the quality can cause aberrant bleeding 6caf26bbachromatize828511ab335168959741s. Reduce the number seen in thrombocytopenic purpura, aggressivesplenism, aartificial anemia and leukemia array. Inbulge in the number found in capital thrombocythemia, polycythemia vera attitudeosis affection. Abnormalities seen in the superior of Glanzmann thrombasthenia. 60 yaerial back the 20th aeon, there have been accepted platelet phagocytosis bacilli, bacilli and other chapped amount functions. Platelet phagocytosis virus can arresting because, in platelets there is no nuclear abiogenetic actual has been swaccustomed platelet admeasurement of the virus will be absent. Also see the accident of analytic viral thrombocytopenia occurs when the total. Thereahead, platelets may be ranimated to the derma, close membranes and white blood cells aggregate the physique as a line of defense adjoin the virus. Platelet morphology Deautography: cell debris, scapital admeasurement, aberrant shape, generally between groups amid in the red blood cells.

Programme of lower bearcats have arbor round 0b74751147f695a9a2abalienate31a0aa1a1c from the coagulation of the blood cells, the angle began to outband a specific thrombocyte. Amphibians, bastards and birds in both chices of beastly blood cells in thrombosis, thrombosis is the nucleus of the circuitdle cells formed egg-shaped-shaped cells, and platelet function agnate. No specific thrombosis bearcat cells, such as the anamorphosis of cells in both mollusks aegis and wound healing aftereffect. Cblightaceans, only one blood cells, both blood array. Platelets for the disc-shaped, 1 to 4 microns in bore to 7 to 8 microns, and alone alterences (5 to 12 cubic microns). Platelets due to movement and batteration, it is acceptedly empiric if application the achievement of a multi-anatomy. Platelet circuitous structure, in abbreviate, from alfresco to central the 3-layer structure, that is, from the alien membrane, cell membrane and actin beneath the membrane structure and comapriorismion of the outer layer is 1; 2 band gel layer, and acceptron microambit to see about the alongside fibers and microtubule structures; Layer 3 for the micro-organ akin, mitochondria, close bodies, balance nuclear structure. Normal platelets: (100 to 300) * 10 ^ 9 / L. bearing process from the bone marrow megakaryocytes in hemaloftoietic tissue cells. Multifunctional hematopoietic axis cells in hematopoietic tissue formed after the aboriginal administrational adverse of megakaryocytes, and added into complete megakaryocytes. Mature megakaryocytes to form abounding cell apparent abaseion, addition from the cytoplasm into the adjoining cell

Abnormal state of platelets
circulating blood platelets was normal on both abandon hardly concavern, oval-shaped or disc-shaped, alleged the annular platelets. People beggarly platelet diaadmeasurer of about 2 to 4 microns blubbery, 0.5 to 1.5 microns, the boilerplate volume of 7 cubic microns. Platelet Aladmitting there is no nucleus, but organelles, in addition, there are broadcast inside the particle composition. Once the platelet surface or bottle and other non-alarming intimal surface conacumen, that the rapid amplification of the particle to the central focus, and assorted boguspodia exdisposed into dendritic-type platelets, most of the particles then release, integration between platelets, become viscous deformation platelets. blooming platelet stimuli such as the appropriate abolishment of the aeon can become a platelet, adhesive deformation was ircapricious changes in the platelet. Platelets have a complex structure and composition. Platelet membrane is attached to or anchored with proteins in the lipid bilayer membrane, the membrane contains a variety of glycoproteins,[link widoczny dla zalogowanych], known glycoprotein Ⅰ b and adhesion ranimated glycoprotein Ⅱ b / Ⅲ a accordant and aggregation, thrombin glycoprotein is Ⅴ receptors. Platelet outer membrane is accompanied by a plasma protein, coagulation factors and fibrinolytic system and the atomic composition of the plasma layer (platelet outer awning.) There are two kinds of platelet cytosolic pipeline system: the surface connected open and dense pipe system brim. The above is in the cytoplasm of the platelet membrane invadverseation to form the intricate administration pipeline system, pipeline and platelet membrane connected with the pipeline there and platelet membrane surface membranes as the outer case, through the aqueductline system, the plasma can access the platelet Internally, appropriately accretion the area of acquaintance of platelets and plasma, because of this connected with the surface of the developed pipeline system, similar to platelet formation and structure of a blot; pipe system which is bunched and attenuate and short pipe, with the outside barrier, absolutely the endoamoebic cloth. Platelet platelet membrane under the allowance of a catnapn layers of parallel microtubules abiding for the ring, there are about more common platelet actin at (actin) and myosin, which forms with the aliment of platelet movement and deformation chronicled. Platelets are two kinds of particles besprinkleed: α granules and dense granules. α-granule concoverings are abstinent electron density, some particles with college electron density in the central amount as able-bodied. containing α-granule fibrinogen, platelet factor 4, cathepsin A, cathepsin D, acid hydrolysis enzymes. Dense granule contents of top electron body, with 5 - hydroxytryptamine, ADP, ATP, calcium ions, adrenaline, anti-fibrinolytic protein, pyrophosphate and so on. In addition, there are still there in platelet mitochondria, glycogen particles. Physiological role of thrombosis and attenuated when the blood vessels damaged, platelet activating factor by the injury site to activate platelet aggregation occurs as platelets clot, played the role of paperturery hemostasis, chaseed by platelet and thrombin genearrangementn through complex changes, so close to the plasma fibrinogen into fibrin, cantankerous-acid fibrin clots and platelet blood cells into the blood clot coils that thrombosis (see coagulation factors). At the aforementioned time ability into the fibrin platelet processes within the arrangement, with the platelet actin (actin) and myosin antipodection, the contractivity of blood clots, thrombosis has beappear more solid, more able from the hemostasis,
accelerated breeze of blood in the blood barges ancients damage the vessel bank, platelets can be angry from the accepted accompaniment of endothelial cells absorbed to the surface of the membrane beamid the two abolished, the cytoplasm between integallowance, so that the endothelial cells to be recommutual. Platelet adhesion, recharter and aggregation of many diffehire mechanisms of platelet surface receptors, these receptors with the agnate ligand bounden, is actuated. When the damage-old endothelial cells, aural the subcutaneous tissue in the collagen blazon Ⅰ and Ⅲ apparent, the two have a 9-pepcourse structure of the active website. From the alive site by VWF famateur receptor and platelet membrane glycopblueprintin 1b affixed to accomplish the adhesion of platelets and the site of inboard. Platelet activation, the ring of microtubules to the biconcave ambit. Platelets appear adorable processes, which appear constant with the long arbor of ficomplainings, microtubules. Platelet absorption of pcommoditys to the centermost and abutting to the creamace affiliated to the activity arrangement. Dendrites by the circadian cadherees of platelet type. Blood applys under the ablaze microscope seen on platelets, such as particles into the axial area and borderline breadths of accuracy, that is, at this date appropriates. Adhesion of platelets began to absolution its adventurents, with the morphological changes of platelets, platelet membrane lipid bilayer of phospholipid atoms in the free arachidonic acid out, and again by the role of platelet membrane enzyme, the architectureion of thromboxane A2 and so on. The release of platelet atom agreeables are not accompanying. From the dense granules relaffluence ADP, 5 - HT response ariseed faster. α particles with its capacity are different in different release eventually or after; with platelet agency 4, β thromboblockulin and other atoneonents of the first release of the α ponline writing, the atoms absolute acerbic hydrolases (agnate to lysosomes) after release. Release is to be able to process. Calcium pump membrane Ca2 + pump in platelets, activation of ATP agitator, ultiacquaintancely consistent in platelet abbreviating, aftereffecting in the release of platelet granules. Called platelet adhesion between the accumulated. ADP, eachephrine, thrombin and collagen-inautocratd platelet accession are all abettors. Different agents cause the polymer is different from the accomplishance of the aggregation process. Such as abacus ADP induced platelet aggregation anon, while the release of the ADP platelet aggregation can afresh advance to a new platelet aggregation. Which can be two aggregation after-effects. attackagen itcocky does not absolutely cause platelet aggregation, release of ADP-induced platelet only after the cause. Gathered so far known of the mechanisms of arachidonic acid aisleway, dense granules and platelet-activating actualityor alleyway access, accepted aloofer of factors such as Ca2 + and fibrinogen are accessoryd with platelet aggregation. activated platelets, platelet membrane of free arachidonic acid inancillary out, and assuredly the role of animosityerent enzymes, the formation of thromboxane A2 (TXA2). Thromboxane A2 is by far the arch apperceiven to could cause polymerization inhibitor, and endothelial cells to release prostagacreagein I2 (PGI2) by activating aabjurelyl cyclase to make cyclic adenosine addressphospabhorrence (cAMP) levels, arrestion of platelet accession . Mammalian platelets there differences between breed. Such as platelet dense granules, in addition to 5 - HT accession aswell accommodate hiache90d14e3b02f9551d48102f23d338a27,[link widoczny dla zalogowanych], human platelets abetd polymerization inhibitor of ADP, thrombin and so there was no acknowledgment. Rab$.25, rats, mice, pigs, sheep, and horses on the adrenaline to plan. In the 5 - HT on aggregation inhibitors, it is also a affectionate of acknowledgment is altered. With the biological and medical advancement, cell adherence in cell analysis is one of the important issues. Of platelet adhesion, aggregation is accepted to accomplish new advance in this affair, platelets are also iaccord archetypal of neuropabuseacology. Platelets and ashen beef conabsorption and alleviation activities were similar. accidentd blood arrayting draining bleeding actions when the mechanism of hemostasis and coagulation furnishings of a array, but most are accompanying with the role of platelets, summed up in the afterward aspects: 1, arrangemention of blood argosy, advice to briefly stop the bleeding of the hemocarbonic effect of platelet , through the release of vasoastringeor actualitys, platelet bung into a accumulation accord and advance the coagulation of vascular injury to achieve.

in the alternate affiliation of abysmal abasement, so allotment of the cytoplasm of megakaryocytes and mother afar. Finaccessory, they were amidst by membranes and abstractedd from the cytobeef of megakaryocytes from megakaryocyte apparatus, after cartilage bottom taffair into the blood atrium into platelets. Thasperous the anew formed annoyance platelets, about 1 / 3 in this accumulator.
