چکیده
AB STRACT: Smoking pa tients show re duc tion of in flam ma tory clin i cal signs that might be as so ci ated with lo cal vasoconstriction and an in creased gingival ep i the lial thick ness. The pur pose of this work was to eval u ate the thick ness of the mar ginal gingival oral ep i the lium in smok ers and non-smok ers, with clin i cally healthy gingivae or with gin gi vi tis. Twenty bi op sies were ob tained from four dif fer ent groups. Group I: non-smok ers with clin i cally healthy gingivae (n = 5). Group II: non-smok ers with gin gi vi tis (n = 5). Group III: smok ers with clin i cally healthy gingivae (n = 5). Group IV: smok ers with gin gi vi tis (n = 5). These bi op sies were histologically pro cessed, se ri ally sec tioned at 5 μm, stained with H. E., and ex am ined by im age anal y sis soft ware (KS400), which was used to per form the morphometric eval u a tion and the quan ti fi ca tion of the ma jor ep i the lial thick ness, the ep i the lial base thick ness and the ex ter nal and in ter nal ep i the lial per im e ters. Dif fer ences be tween the four groups were an a lyzed us ing ANOVA test and Tukey’s test. The cri te ria for sta tis ti cal sig nif i cance were ac cepted at the prob a bil ity level p < 0.05. A greater ep i the lial thick ness was ob served in smok ers in de pend ent of the gingival health sit u a tion. DESCRIPTORS: Gingiva; Ep i the lium; To bacco.

متن کاملRoughing up Smoothened: chemical modulators of Hedgehog signaling
Small-molecule antagonists of Hedgehog-pathway signaling, such as cyclopamine, have been known for some time. Now, small-molecule agonists of the Hedgehog pathway have also been identified. The finding that both antagonists and agonists target the protein Smoothened supports the emerging hypothesis that Smoothened may be regulated by endogenous small molecules.
متن کاملThyroid Hormone Regulates the Expression of the Sonic Hedgehog Signaling Pathway in the Embryonic and Adult Mammalian Brain
Thyroid hormone is important for development and plasticity in the immature and adult mammalian brain. Several thyroid hormone-responsive genes are regulated during specific developmental time windows, with relatively few influenced across the lifespan. We provide novel evidence that thyroid hormone regulates expression of the key developmental morphogen sonic hedgehog (Shh), and its coreceptor...

U na{em ispitivanju izmjerili smo titar protutijela protiv tetanusnog toksina u serumu 437 osoba srednje i starije dobi iz gradske i seoske sredine u Koprivni~ko-kri`eva~koj `upaniji. Ispitanici su bili u dobi od 45 do 95 godina. Dvije tre}ine ispitanika bile su `ene (66 %). Veliki postotak ispitanika (39,1%) nije znao da li je i kada je cijepljen protiv tetanusa. Tra`eni minimalni za{titni tit...
