Extracellular Matrix,ECM is the mass that locates the substratum of epithelium cell or endotheliocyt around connective tissues , provide mechanics support and physics intensity for the organisation and the organ even to the completeness of whole organism. But ECM should not only be regarded as the organisation part which provide mechanics support and the physics intensity for the organisation and organism.ECM is one of the necessary condition of blood vessel formation, among them the Type IV collagen(Col-IV),Lammin(LM),Fibronection(FN) are the closest part with ECM. They are the necessary component of ECM to maintain the cell form and keep cell function and organisation completeness .They are all protein which are combined in the endoplasmic reticulum and secreted outside the cell, and assume the function of shield,strain and osmoses. Col-IV, LM and FN are combined in great bulk in the overfull accretive endotheliocyte,on the contrary they can also promote the adhesion,move,growth and differentiation of endotheliocyte. There has been reported in a document that the expression of ECM is strongly positive in theproliferative capillary hemangioma tissue ,there are prominence disparity with the expression in normal tissue and disvolution tissue.BleomycinA5is one kind of resist tumor pharmaceu- ticals ,it is made in our country.It can be used to cure all kinds of infant capillary haemangioma and has gained no- table curative effect. BleomycinA5 can directly harm DNA's synthesis inside the endotheliocyte nucleus , and prevents the combination of thymus deoxidation pyrimidine and DNA , when injects the BleomycinA5 into the hemangioma it can rapidly restrain the hyperplasia of endotheliocyte and impel the hemangioma retrogression. The curative effect have been acknowledged both inside and outside the country. What changes will be turned out in the ECM of hemangioma after the BleomyciA5 have been used ?There is not correlative reports both inside and outside the country. So we designed the topic in order to explain the histology change in the course of hemangioma resolution after the treatment of BleomyciA5,and make the disvolution mechanism of hemangioma clear and accumulation experience for the non-surgical operation therapy of hemangioma.The capillary hemangioma is the benign soft tissues tumor of many of babys .The incidence of it is about 3%-5% .This is a medical science problem that have been puzzled vast doctors and patiens for a long time. the method of curing hemangioma is more at present .for example:surgery therapy, glucocorticoid therapy,BleomycinA5 therapy, Interferon therapy, submethylorchid therapy, hardener therapy, carbamide therapy, anhydrous alcohol therapy,freezing therapy,laser therapy,microwave therapy and so on. The above various therapy all needs to accept curing in the hospital ,the effect of surgical operation is the best one among all of the therapys, but the baby has to be cured in the hospital and existing many inconvenience, and there is one of unavoidable shortcoming is that the scar generation after operating. It is fairly more sure that the effect of Bleomycin A5 is injected to cure aspect table capillary hemangioma jn these therapies. but this method is hard to make the drugs uniform distribution in the hemangioma tissue , hence measures with the medicament microweight will not cure it thoroughly , with medicament overdos will appear the tissue necrosis . Is the subject be concerned about jointly in medical matters circle for many years to develop one kind of convenience,safety and reliable external use medicine.It will be like curing other skin disease by uses the form of emulsion. We attempt to use BleomycinA5 emulsion to cure baby's skin capillary haemangioma , and has carried on the initial investigation . Since Bleomycin A5 was used to cure capillary hemangioma we havn't seen the correlative reports about the change of extracellular matrix after BleomycinA5 emulsion be used inside or outside the country,and we also havn't seen the correlative reports abou...
