"[Latar Belakang: magnesium menjadi bahan yang menarik untuk implan karena magnesium dapat menyelesaikan dalam tubuh kita. Tetapi bahan magnesium standar memiliki kecepatan tinggi dari korosi dalam tubuh kita dan menghasilkan beberapa gas dalam proses, yang tubuh kita tidak bisa mentolerir. ECAP (Equal Chanel sudut Menekan) prosedur untuk magnesium dapat menghasilkan magnesium dengan partikel yang jauh lebih kecil. Partikel kecil berarti lagi korosi, berarti produksi gas jumlah yang lebih kecil. Biokompatibilitas bahan masih menjadi pertanyaan. Dalam penelitian ini kami menyelidiki ECAP magnesium partikel tenggelam dengan fibroblast dan garis sel osteoblas dan menggunakan real time PCR untuk mendeteksi produksi interleukin 6 sebagai indikator peradangan tingkat dan interleukin 8 sebagai penanda angiogenesis kemotaksis. kami juga melakukan uji MTT untuk melihat korelasi antara sitokin produk dan proliferasi dari garis sel. Tujuan: untuk mengamati tingkat peradangan dan sifat angiogenesis chemotactic dari ECAP magnesium dalam garis sel osteoblas dan fibroblast. Metode: assay MTT dan RT-PCR untuk mengevaluasi interleukin 6 dan interleukin 8 produksi fibroblast dan osteoblast garis sel. Evaluasi di 1,3,7days setelah perawatan., ackground: magnesium become interesting material for implant since magnesium can resolve in our body. But standard magnesium material had high speed of corrosion in our body and produce some gas in the process, which is our body can not tolerate. ECAP ( Equal Chanel Angular Pressing ) procedure to magnesium can produce magnesium with far smaller particle. Small particle means longer corrosion, means smaller amount gas production.
Biocompatibility of the material is still a question. In this study we investigated ECAP magnesium particle immersed with fibroblast and osteoblast cell line and using real time PCR to detect the production of interleukin 6 as an inflammation rate indicator and interleukin 8 as the chemotactic angiogenesis marker. we also perform MTT assay to see the correlation between cytokines products and proliferations of the cell lines.
Purpose : to observe the inflammation rate and chemotactic angiogenesis properties of the magnesium ECAP in the osteoblast and fibroblast cell line.
Method : MTT assay and RT-PCR to evaluate interleukin 6 and interleukin 8 production in fibroblast and osteoblast cell line. Evaluate at 1,3,7days after the treatments]"

"Latar Belakang: PRF adalah trombosit generasi kedua yang digunakan untuk mempercepat penyembuhan jaringan lunak dan keras dan merupakan matriks fibrin alami yang mengandung platelet dan leukosit sitokin. Pemberian growth Factor yang cukup lama (TGF β1) dari penambahan PRF pada DPBB dapat mengakibatkan peningkatan regenerasi tulang dibandingkan dengan pemberian DPBB saja. Tujuan: mengevaluasi pengaruh platelet rich fibrin dalam meningkatkan regenerasi tulang yang dilihat melalui konsentrasi TGF β1 dan osteocalcin. Metode: autologous PRF dibuat dengan menggunakan 10 ml darah yang dikumpulkan dari regio antecubital dari relawan. Sampel darah diperlakukan sesuai dengan protokol PRF (Dohan et all.2006). Bekuan fibrin di tengah tabung digunakan sebagai tambahan untuk bahan bone graft (DPBB). Kelompok-kelompok ini sampel PRF diinkubasi pada suhu 370C dan 5% CO2 selama 1 hari, 5 hari dan 7 hari. Semua sampel dipanen pada waktu yang tepat dan disimpan lalu diperiksa Enzyme-Linked Immunosorbent Assay (ELISA) analisis untuk TGF β1 tingkat dan tingkat ostecalcin. Hasil: terdapat perbedaan bermakna dari PRF + DPBB dibandingkan dengan DPBB di hari 1, dari PRF dibandingkan dengan kontrol pada hari 5, dari PRF + DPBB dibandingkan dengan kontrol pada hari ke 7, dan dari DPBB dibandingkan dengan kontrol pada hari ke 7 (p <. 05). Terdapat perbedaan bermakna dari PRF + DPBB dibandingkan dengan kontrol pada hari ke 1,5 dan 7, dari DPBB dibandingkan dengan kontrol pada hari 1,5, dan 7, dan dari PRF membandingkan toPRF + DPBB dan DPBB (p <.05). Kesimpulan: Penambahan PRF atau PRF + DPBB dalam kultur osteoblas dapat meningkatkan konsentrasi TGF β1 dan osteokalsin, yang dimulai 1 hari ke hari 7

Background: PRF is a second generation platelet used to accelerate soft and hard tissue healing and is a strictctly autologous fibrin matrix containing a large quantitiy of platelet and leukocyte cytokines. Given prolonged growth factor (TGF β1) from PRF treatment in DPBB might result in increasing bone regeneration compare to those treated with DPBB. Purpose: evaluate the influence of platelet rich fibrin in enhancing natural bone regeneration through the levels of TGF β1 and osteocalcin. Method: Autologous PRF was prepared by using 10 ml of autologous whole blood collected from the antecubital regio of a volunteers. Blood samples were treated according to the PRF protocol (Dohan et all.2006). A fibrin clot in the middle of tube was used as an adjunct to grafting material (DPBB). These groups of PRF samples were incubated at 370C and 5%CO2 for 1 day, 5 days and 7 days. All sample were harvested at the appropriate time and and stored for later Enzyme-Linked ImmunoSorbent Assay (ELISA) analysis for TGF β1 level and osteocalcin level. Result: There are significantly differents from PRF+DPBB compare to DPBB at day 1, from PRF compare to control at days 5, from PRF+DPBB compare to control at day 7, and from DPBB compare to control at days 7 (p<.05). There are significantly differents from PRF+DPBB compare to control at day 1,5 and 7, from DPBB compare to control at days 1,5,and 7, and from PRF compare toPRF+DPBB and DPBB (p<.05). Conclusion: Addition PRF or PRF + DPBB in cultured osteoblasts can increase the concentration of TGF β1 and osteocalcin, which began 1 day to day 7"
