Abstract

Apical periodontitis is an inflammation and destruction of periradicular tissues caused by bacteria of endodontic origin.Actinomyces israel II has been consistently isolated from the periapical tissue of teeth which did not respond to properconventional endodontic treatment. Inflammatory processes are characterized by the dynamic influx of neutrophils whichis initiated by chemical signals including chemotactic factors. The purpose of this preliminary study was to evaluatechemotactic response of neutrophil to A. israel II. Chemotactic activity was performed in vitro with blind well chambers.Hanks balanced salt solution (HBSS) containing 104, 106, and108 A. israel II, 10-8 M N-formyl-L-methionyl-L-leucyl-Lphenylalanine (fMLP), or HBSS were placed in the lower wells of the chamber and covered with 5 µm polycarbonatemembrane filters. Neutrophils suspension (2X105 cells) was placed in the upper compartment and incubated for 60 minsat 37°C in a humidified atmosphere with 5% CO2. The filters were then removed and stained with Giemsa. Statisticalanalysis used ANOVA test. The result showed that there were significant differences of the number of neutrophils amonggroups (p<0.05), indicating that A. israel II induced neutrophils chemotaxis. The number of neutrophils migrations inresponse to 106, and108 A. israel II were significantly greater compared to 10-8 M fMLP (p<0.05). In conclusion, A. israelII directly induced chemotactic response of neutrophil, therefore, A. israel II may contribute to the pathogenesis of apicalperiodontitis through modulation of the host innate immune response

Abstract

Tuberous sclerosis complex (TSC) is a hamartomatous disease with defects in tuberin (TSC2) that can be autosomaldominant inheritance or spontaneous mutation. Mutation of the TSC-2 gene encoding tuberin on chromosome 16p13.3increases to the clinical disorder of tuberous sclerosis characterized by the development of hamartomas. In the presentstudy, the antitumor activity of pcDNA3.1-TSC2 sense in an oral tongue cancer Supri’s clone-1 (SP-C1) wasinvestigated. An expression vector containing sense-oriented rat TSC-2 pcDNA with pcDNA3.1 and transfected to cell(SP-C1) to regulate the expression of TSC-2 gene in each transfectant was constructed. MTT assay was performed toexamine the SP-C1 cell growth suppression transfected by pcDNA3.1-TSC2. Caspase-3 and -9 were conducted toobserve the induction of cell apoptosis. Western blotting analysis was carried out to determine the protein level of TSC-2,p27Kip1 and -tubulin. The results showed that, overexpression of TSC-2 exerted the growth inhibitory effect of SP-C1cell and markedly increased apoptosis via caspase-3 and -9 pathways (P=0.001). Sense-oriented SP-C1-cDNA3.1-TSC-2cancer cells have a high expression of p27Kip1. In conclusion, pcDNA3.1-TSC-2 sense increased the antitumor activity oforal tongue cancer SP-C1 cell through p27Kip1 induction.

Abstract

The usage of orthodontic appliance is to correct malocclusion involves alveolar bone remodeling. This process isstimulated by mechanical force which obtained from the activation orthodontic appliance. The force was used to depressteeth and the tissues surrounding it. This stress will become a signal to activate heat shock response yielding HSPsynthesis. HSP25 plays a part in osteoclastic bone resorption and osteoblastic new bone forming. The aim of this studywas to explore the change of osteoclast and osteoblast HSP25 expression in the different mechanical force induction atpressure and strain area. The subject was guinea pig (Cavia sp), divided into 2 groups. Control group did not useorthodontic appliance and treatment group was given mechanical force as 90 g, 120 g, and 150 g. Time usage oforthodontic appliance was 5 and 10 days. Osteoclast and osteoblast HSP25 were measured by counting cells after beingconducted by immunohistochemistry method. The result showed that osteoclast HSP25 expression at pressure area on allgroups had increased value compared to strain area and was different statistically. On the other hand, osteoblast HSP25expression at strain area had increased value was compared to at pressure area and especially in group of 120 g and 10days had difference statistically. In conclusion, different mechanical force induction could influence osteoclast andosteoblast HSP25 expression. HSP25 may represent one of the factors that influences osteoclast and osteoblast cellularactivity and coupling process between osteoclast and osteoblast.

Abstract

Fluoride plays an important roles in reducing dental caries by improving remineralization process and strengthening emailthrough forming fluoroapatite which is more resistant to acid. Fluoride systemic mode without passing metabolism withsmall and controlled dose need to be developed such as Transdermal route. The aims of this research was to find iffluoride solution with and without enhancer solution is able to penetrate to skin. Quasy experimental design with post testonly control group design as research approach was used. Transport test with Franz Like Diffusion cell used as theinstrument in vitro skin permeation test with hairless and full thickness mouse skin as membrane between donor andrecipient cell. Two groups of donor cell was fluoride solution and fluoride added with chemical enhancer: oleic acid andiso propyl alcohol (IPA) solution and recipient solution was CMF PBS 0,1 M pH 7,4. Control group was oleic acidsolution. Sample was taken for time interval of 4, 20 and 24 hours and Fluoride containt was measured by PotensiometerSpesific Ion Fluoride. The results showed that there was an influence of transport test both on NaF solution andNaF+oleat acid and IPA solution (p= 0.00) and (0.00) on fluoride permeation, however there was no significant differenceon control group (p= 0.07). NaF added with chemical enhancer solution and it had higher penetrating power than othersolution. It can be concluded that added chemical enhancer can increase the penetration of fluoride.
