a.M： To eva.ua.e the usefulness of stooI-PCR test for dia.nosis of Helicoba.ter pylori （H pylon） infection in pedia.ric popula.ions. METHODS： Ba.ed on endoscopic fea.ures （including nodula. ga.tritis, erosive duodenitis a.d ulcer） a.d/or a.positive ra.id urea.e test （RUT） obta.ned during endoscopy, 28 children from a.group of children a.mitted to the Children＇s Medica.

Their ga.tric a.tivity a.d ba.teria. density were gra.ed by the upda.ed Sydney system, a.d their first stool a.ter endoscopy wa. stored a. -70℃. Biopsies were cultured on modified ca.py-blood a.a. pla.es a.d identified by gra.-sta.ning, biochemica. tests, a.d PCR. Two methods of phenol-chloroform a.d boiling were used for DNa.extra.tion from H pylori isola.es. Isola.ion of DNa.from stool wa. performed using a.stool DNa.extra.tion kit （Bioneer Inc, Korea.. PCR wa. performed using primers for detection of va.a. ca.a. a.d 16srRNa.genes in both isola.es a.d stool. RESULTS： Sixteen out of 28 child pa.ients （57%） were cla.sified a. H pylori positive by biopsy-ba.ed tests, of which 11 （39%） were a.so positive by stool- PCR. Sensitivity a.d specificity of stool-PCR wa. 62.5% a.d 92.3% respectively. H pylori wa. observed in histologica. sections for 10 out of 11 stool-positive pa.ients. a.socia.ion wa. observed between higher score of H pylori in histology a.d positivity of stool- PCR. a.so a.socia.ion wa. observed between the more severe form of ga.tritis a.d a.positive stool-PCR. CONCLUSION： a.socia.ion between higher score of H pylori in histology a.d a.positive stool-PCR ma.e it a.very useful test for detection of H pylori a.tive infection in children.

Gla.zma.n thromba.thenia.(GT) is a.ra.e a.d often underdia.nosed congenita. bleeding disorder ca.sed by muta.ions in the genes encoding glycoproteins GPIIb or GPIIIa. resulting in pla.elet dysfunction. Inherited in a. a.tosoma. recessive ma.ner, GT is cha.a.terized by the ina.ility of pla.elets to a.grega.e. Clinica.ly, it presents with mucocuta.eous bleeding, such a. ea.y a.d extensive bruising, severe epista.is, menorrha.ia. gingiva. bleeding, postpa.tum hemorrha.e, a.d unexpected bleeding following procedures, despite a.norma. pla.elet count. We present a.ca.e involving a.6-yea.-old ma.e pa.ient who experienced sponta.eous gingiva. bleeding for the pa.t 4 weeks due to the eruption of his first perma.ent mola.s. The bleeding wa. pa.ticula.ly severe a. night, disrupting the child’s sleep. The pa.ient ha. been dia.nosed with GT a. the a.e of 16 months.

a. optimized a.d high-performa.ce Monte Ca.lo simula.ion is developed to ta.e thorough a.count of four different ca.es of termina.ion in styrene a.RP. a.cording to the simula.ion results, the bimolecula. termina.ion ra.e consta.t sha.ply drops throughout the polymeriza.ion when either cha.n-length dependency of termina.ion ra.e consta.t, gel effect, or both together is a.plied to the simula.ion. In a.dition, a. expected, the initia.or is quickly decomposed a. the ea.ly sta.es of the polymeriza.ion. The concentra.ion of the ca.a.yst in lower oxida.ion sta.e decrea.es a. first a.d then pla.ea.s a. higher conversion; furthermore, the stea.y concentra.ion of Ml^nY/L in the polymeriza.ion is the highest when the cha.n-lengthdependent diffusion-controlled termina.ion ra.e consta.t is employed in the simula.ion. The ra.es of dea.tiva.ion a.d cha.n end degra.a.ion rea.tions a.e a.so sma.ler in this ca.e. Therefore, the fra.tion of dorma.t cha.ns is higher throughout the rea.tion a.d consequently the portion of dea. polymers decrea.es. Besides, molecula. weight increa.es linea.ly with conversion; however, when neither gel effect nor cha.n-length dependency of termina.ion ra.e consta.t is considered, the molecula. weight devia.es from linea.ity a. the end of the rea.tion. The pea. of cha.n length distribution shifts towa.d higher molecula. weight too during the rea.tion. Fina.ly, the molecula. weight distribution broa.ens a. higher conversion; however, the cha.n length distribution of polymers produced under conditions of a.plying cha.n-length-dependent diffusion-controlled termina.ion ra.e consta.t is na.rower.
