"ABSTRAK Pendahuluan. Kesulitan dalam tatalaksana defek tulang yang luas merupakan salah satu tantangan dewasa ini. Selain tatalaksananya yang kompleks juga dapat memberikan dampak jangka panjang negatif yang berat. Penggunaan BMP-2 dalam tatalaksana fraktur dengan defek tulang yang luas memegang peranan penting. BMP-2 berperan pada proses osteogenesis dan chondrogenesis dan menghambat osteoclastogenesis melalui RANKL signaling. Penelitian ini bertujuan untuk mengetahui efek dari perbedaan dosis BMP-2 terhadap penyembuhan fraktur dengan defek tulang yang luas. Metode. Penelitian dilakukan di Laboratorium Animal Gizi di FKUI dan Laboratorium Patologi Anatomi FKUI-RSCM, pada bulan Juli hingga September 2015. Desain penelitian adalah randomized post test control group. Sejumlah 25 ekor tikus putih Sprague Dawley dengan usia 3-4 bulan dan berat badan antara 250 ? 350 gram, dibagi secara acak menjadi kelompok kontrol hidroksiapatit (HA) saja dan kelompok kombinasi HA + BMP-2 1 μg/ml, HA + BMP-2 5 μg/ml, HA + BMP-2 10 μg/ml, HA + BMP-2 20 µg/ml. Tiap kelompok dilakukan tindakan berupa frakturisasi dengan defek tulang 10mm pada femur kanan dan dilakukan fiksasi interna dengan menggunakan intramedullary k-wire ukuran 1,4 mm secara retrograd. Setelah 6 minggu dilakukan penilaian secara histomorfometri, radiologis dan Scanning Electron Microscope (SEM). Hasil. Berdasarkan hasil penelitian secara histomorfometri ditemukan terdapat perbedaan rerata total area kalus yang bermakna diantara kelompok penelitian (p<0,001),terdapat perbedaan bermakna rerata area penulangan antara kelompok kontrol dengan kelompok 1 μg/ml, 5 μg/ml, 10 μg/ml, 20 μg/ml (masing-masing p=0,009, p=0,016, p=0,009 dan p=0,016), terdapat perbedaan bermakna rerata area kartilago antara kelompok kontrol dengan kelompok 1 μg/ml, 5 μg/ml, 10 μg/ml, 20 μg/ml (masing-masing p=0,009, p=0,009, p=0,009 dan p=0,028), terdapat perbedaan bermakna rerata area fibrosis antara kelompok kontrol dengan kelompok 1 μg/ml dengan kelompok kontrol dan 10 μg/ml(masing-masing p=0,047 dan p=0,009).Secara radiologis dengan RUST score didapatkan perbedaan bermakna antara kelompok kontrol dengan kelompok 1 μg/ml, 5 μg/ml, 10 μg/ml, 20 μg/ml (masing-masing p=0,005, p=0,006, p=0,005 dan p=0,006). Dengan SEM didapatkan gambaran kalus yang lebih homogen dan padat pada kelompok 10μg/ml dibandingkan dengan 5 μg/ml dan 20 μg/ml. Kesimpulan: Pemberian BMP-2 dapat menstimulasi proses penyembuhan fraktur pada defek tulang luas (critical bone defect) yang bermakna secara statistik, histomorfometri, radiologis maupun secara kualitatif dengan SEM. Terdapat dosis optimal dalam pemberian BMP-2.ABSTRACT Introduction: Difficulties in the management of extensive bone defects is one of today's challenges.

"Pendahuluan: Penanganan nonunion dan delayed union bukanlah penanganan yang murah dan mudah. Berbagai metode telah dilakukan untuk mengatasi masalah tersebut. Beras angkak terbukti memiliki peranan dalam penyembuhan fraktur. Beras angkak, mengandung monakolin, suatu senyawa dengan aktivitas sebanding lovastatin. Pemberian statin secara lokal dan oral terbukti meningkatkan penyembuhan tulang dengan menginduksi diferensiasi osteoblas melalui peningkatan ekspresi BMP-2. Penelitian ini dilakukan untuk membuktikan efektivitas monakolin pada beras angkak dalam meningkatkan ekspresi BMP-2 dan penyembuhan fraktur pada model delayed union tikus sprague- dawley. Material dan Metode: Studi eksperimental pada 24 hewan coba tikus putih Sprague-Dawley (SD) yang telah mengalami patah tulang femur disertasi dengan gangguan vaskularisasi (model delayed-union). Hewan coba dibagi menjadi empat kelompok (n=6) terdiri dari; kelompok pemberian ekstrak monakolin selama empat minggu (PM4), kelompok pemberian ekstrak monakolin selama dua minggu (PM2), kelompok kontrol empat minggu (KM4) dan kelompok kontrol dua minggu (KM2). Setelah dilakukan sacrifice pada minggu kedua dan keempat, dilakukan penilaian ekspresi BMP-2 secara semikuantitatif dengan pewarnaan imunohistokimia melalui skor imunoreaktif (IRS). Analisis histomorfometri untuk menilai penyembuhan fraktur dengan mengukur persentase area fibrosa, tulang rawan dan tulang imatur. Hasil: Pada evaluasi parameter IRS dan histomorfometri didapatkan ekspresi BMP-2 lebih tinggi (p=0.03), persentase area fibrosa lebih sedikit (p=0.005) dan area tulang rawan lebih besar (p=0.04) pada kelompok PM2 dibandingkan dengan kelompok KM2. Selain itu didapatkan pula secara ekspresi BMP-2 lebih tinggi (p=0.011), presentase area tulang imatur lebih besar (p=0.01), dan presentase area fibrosa lebih kecil (p=0.03) pada kelompok PM4 dibandingkan dengan kelompok KM4. Di sisi lain, didapatkan presentase area fibrosa lebih kecil (p=0.02), area tulang rawan lebih sedikit (p=0.05), dan peningkatan area tulang imatur lebih besar (p=0.04) pada kelompok PM4 dibandingkan dengan kelompok PM2. Ekspresi BMP-2 sama-sama meningkat pada kelompok PM2 dan PM4. Kesimpulan: Pemberian monakolin pada beras angkak pada model delayed-union tikus Sprague Dawley terbukti meningkatkan ekspresi BMP-2 dan meningkatkan penyembuhan fraktur.

Introduction: Management of nonunion and delayed union could be difficult and expensive. Various methods have been studied to overcome this problem. Red-yeast-rice has a role in fracture healing. Red-yeast-rice contains monacolin, which has similar activity to lovastatin. Local application and oral administration of statins have been shown to improve bone healing by inducing osteoblast differentiation and matrix production via increasing BMP-2 expression. This study was conducted to prove the effectiveness of monacolins inside red-yeast-rice in increasing the expression of BMP-2 and fracture healing. Methods: This experimental animal study was conducted using 24 delayed union models Sprague-Dawley (SD) Rats. There were 4 groups (n=6), consist of; 4-weeks-given-monacolin group (PM4), 2-weeks-given-monacolin group (PM2), 4-weeks-control group (PM2) and 2-weeks control group (KM2). After they were sacrificed in the second and fourth weeks, immunohistochemical staining was conducted to evaluate BMP-2 expression by Immunoreactive Score (IRS). The histomorphometric evaluation was also conducted to evaluate fracture healing by measuring fibrous area, cartilage area, and woven bone area percentage. Results: There was significantly higher BMP-2 expression (p=0.03), less fibrous area (p=0.05), and larger cartilage area (p= 0.04) in the PM2 group compared to the KM2 group. There was significantly higher expression of BMP-2 (p=0.011), larger woven bone area (p=0.01), and less fibrous area (p = 0.03) in the PM4 group compared to the KM4 group. It was also presented, there was a significantly less fibrous area (p=0,02), larger cartilage area (p=0.05), and larger woven bone area (p=0.04) in the PM4 group compared to the PM2 group. The expression of BMP-2 in the PM2 group was as high as the PM4 group. Conclusion: Monacolin in red-yeast-rice effectively increased BMP-2 expression and fracture healing in the delayed union model of SD rats."

Background: Ti-6Al-4V is one of the most commonly used implant materials. In an effort to reduce the cost of producing titanium implants, the material is heated to optimize their final product. One of the conditions that need to be met for new implant material is the biocompatibility of the material for the surrounding tissue.

Objective: To understand the effect of implantation of TiI 6Al-4V ELI material that was heated at 10500C on the femur of Sprague Dawley rats through histological studies.

Methods: The experimental research design used in this study with female Sprague Dawley mice was divided into three groups: the treatment group; normal control group; and the deformed control group, which made a hole in the femur. Two mice were used in each group. In the treated group, femur defects were implanted with the implant material 10500C EL-Ti-6Al-4V. Mice were sacrificed after four weeks and evaluated histologically using modified Salkeld Histological Scoring.

Results: The histological score of the sample group 1 treated was 3, which means almost perfect bone regeneration, indicated by the appearance of mineral cartilage. The values ​​for the sample 2 treatment group and the sample defect control group 1,2 are 2, which means bone regeneration only reaches the fibrocartilage formation phase.

Conclusion: Bone regeneration can be obtained around the implantation site of ELI Ti-6Al-4V implant material heated by 10500C which is indicated by the presence of fibrous tissue, fibrocartilage, and mineralized cartilage."

"Belum banyak bukti ilmiah yang mendukung efektivitas cuka apel. Namun, penggunaannya sebagai agen penurun berat badan telah semakin meluas. Bahkan, di berbagai iklan penjualan produk, suplemen makanan ditampilkan seolah-olah memiliki manfaat seperti obat. Untuk itu, peneliti mengadakan penelitian eksperimental dan hipotesis yang akan diuji adalah efektivitas cuka apel tak sebaik yang dimiliki obat standar dalam menurunkan berat badan tikus strain Sprague Dawley. Tikus Sprague Dawley dengan berat 190- 250 gram digunakan sebagai sampel dalam penelitian ini. Ada 24 ekor tikus yang terbagi ke dalam 3 kelompok, yaitu kelompok kontrol (sebagai kontrol negatif), kelompok mazindol (sebagai kontrol positif), dan kelompok cuka apel. Ketiganya mendapat jenis makanan dan minuman yang sama. Berat badan dan tingkah laku tikus diamati selama dua minggu. Data berat badan sebelum dan sesudah terapi diambil dan dianalisis menggunakan uji hipotesis One Way Anova. Peneliti mendapati tidak adanya penurunan berat badan pada ketiga kelompok perlakuan. Akan tetapi, berat badan tikus terus mengalami peningkatan dari hari ke hari. Data peningkatan berat badan tersebut menunjukkan adanya perbedaan bermakna secara statistik antara kelompok kontrol dan kelompok cuka apel (p = 0,012). Sementara itu, tidak adanya perbedaan bermakna terlihat baik antara kelompok kontrol dan mazindol maupun kelompok mazindol dan cuka apel.

Researcher found that there is significance difference of leftovers between control and apple cider vinegar group (p = 0,000) using One Way Anova test and (p = 0,000) using Post Hoc test.Meanwhile there is no significance difference between control and mazindol group (p = 0,623) using Post Hoc hypothesis test. In conclusion, the effectiveness of apple cider vinegar in suppressing appetite is better than mazindol., Apple cider vinegar has beend used for ages in suppressing appetite in order to lose weight. Meanwhile, there are only few valid studies regarding this matter.Thereby, researcher conducted an experimental study and define the effectiveness of apple cider vinegar is not as good as mazindol for suppressing appetite as the hypothesis. Researcher used Sprague Dawley strain rats which weight are 190-250 grams as research sample.

"PendahuluanSalah satu tantangan dalam tatalaksana fraktur saat ini adalah rekonstruksi fraktur dengan defek tulang yang luas, di mana dibutuhkannya restorasi alignment dan fiksasi yang stabil untuk keberhasilan rekonstruksi. Pada kasus fraktur dengan defek tulang tidak ada lagi komponen osteoinduksi dan osteokonduktif sehingga diperlukan penggunaan graft tulang ataupun tindakan transport tulang. Walaupun perkembangan teknologi dan kemajuan dalam pembedahan orthopaedi telah berkembang saat ini, hasil akhir dari penyembuhan tulang paska pembedahan pada beberapa kasus fraktur akan mengalami penyembuhan tulang yang kurang baik yang akhirnya akan menyebabkan defek ataupun non-union dari fraktur tersebut.MetodeDesain penelitian adalah studi post test control group design. Sampel yang digunakan adalah dua puluh delapan tikus putih Sprague Dawley yang telah mengalami maturasi skeletal (8-12 minggu), dibagi menjadi empat kelompok, tiap tikus akan dilakukan tindakan fraktur dengan defek tulang pada tulang femur selebar 4mm, kemudian tikus dibagi berdasarkan implantasi yang diberikan, yaitu kelompok kontrol, kelompok implantasi amnion liofilisasi steril, kelompok implantasi xenograft morcalized bovine, dan kelompok implantasi kombinasi amnion dengan xenograft. Hewan coba akan dikorbankan setelah 8 minggu, kemudian dilakukan pemeriksaan radiologis dan histopatologis dari fraktur. Evaluasi radiologis menggunakan skor menurut Lane dan Sandhu, evaluasi histopatologis menggunakan skor menurut Salkeld.HasilBerdasarkan uji statistik non parametrik Kruskal-Wallis terhadap skor radiologis tulang pada minggu ke-8 paska pembedahan didapat nilai p 0,25. Secara statistik dapat diambil kesimpulan bahwa tidak terdapat perbedaan bermakna perbandingan skor radiologis antara empat kelompok tersebut. uji statistik non parametrik Kruskal-Wallis pada skor histopatologis menurut Salkeld minggu ke-8 paska pembedahan didapat nilai p 0,001 secara statistik, dapat diambil kesimpulan bahwa terdapat perbedaan bermakna perbandingan skor histopatologis antara empat kelompok tersebut.KesimpulanSkor radiologis pada implantasi amnion liofilisasi steril dibanding dengan kelompok kontrol pada fraktur dengan defek tulang tidak memberikan perbedaan bermakna, sementara skor histologis memberikan perbedaan percepatan penyembuhan bermakna pada implantasi amnion liofilisasi steril dibanding dengan kelompok kontrol. Skor radiologis dan histologis pada implantasi xenograft morcalized bovine dibanding kelompok kontrol tidak memberikan perbedaan percepatan penyembuhan bermakna. Skor radiologis pada implantasi kombinasi amnion liofilisasi steril dan xenograft morcalized bovine dibanding dengan kelompok kontrol tidak memberikan perbedaan bermakna, sementara skor histologis memberikan perbedaan percepatan penyembuhan bermakna dibanding dengan kelompok kontrol.

Introduction

One of the current chalenge on fracture treatment is reconstruction of fracture with critical size bone defect, where the restoration of the alignment dan stable fixation for succesfull result is necessary. bone graft or bone transport is usually needed for bone defect reconstruction because there isnt any osteoinductive and osteoconductive component on fracture with bone defect. Although new technologies and advances in orthopaedic surgery have enhanced fracture healing and surgical outcomes, there are fracture that continue to be deficient in bone repair or become non-union.

Methode

The research design is post test control group using twenty eight skeletally matured Sprague Dawley rats, divided into four groups, 4mm sized femoral defects were surgically created in the right femur of 28 rats. 7 rats were ran­domly assigned to each treatment group, in which the femoral defect was filled with sterile lyophilized amnion, morcalized bovine xenograft and combination. In the empty defect group (control group) defects were left empty. Animals were sacrificed at 8 weeks postoperatively. Then the radiologic and histopathologic examination were completed. Radiologic evaluation using Lane and Sandhu score, histologic evaluation using Salkeld score.

Result

Non parametric Kruskal-Wallis statistic analysis for the radiologic score 8 weeks postoperatively reveal p value 0,25 which mean there is no significance difference between four groups. However for the histopathologic score statistic analysis examination reveal the p value 0,001 which mean there are significance differences between four groups. The statistic analysis for histopathologic is then continued with Man Whitney analysis.

Conclusion

Regarding the radiologic score, amniotic membrane has similar radiological score to control, however the histopathologic score is better. Xenograft have similar radiological and histopathological score to the control. Combination of amniotic membrane with xenograft has better histopathological score to control. Although the radiologic score is similar.
