Latar Belakang: Sirkumsisi adalah prosedur bedah untuk menghilangkan kulit prepusium. Prosedur ini melibatkan proses penyembuhan luka yang meliputi 3 fase: inflamasi, pembentukan jaringan, dan remodeling jaringan. Tenascin-c adalah protein matriks ekstraselular yang diekspresikan pada saat perlukaan, perbaikan, dan regenerasi jaringan. Tenascin-c ditemukan pada area inflamasi, terutama di tepi perlukaan. Riset ini bertujuan mengidentifikasi korelasi antara ekspresi tenascin-c pada tepi luka sirkumsisi dengan resolusi inflamasi pada penyembukan luka sirkumsisi. Metode: Sampel preputium didapatkan dari kegiatan sirkumsisi masal, kemudian sampel melalui histotechniques dan immunohistokimia spesifik untuk tenascin-c. Data juga diperoleh dari wawancara yang dilaksanakan 14 hari setelah sirkumsisi. Wawancara diikuti oleh observasi fisik untuk menentukan resolusi inflamasi pada perlukaan pasien. Hasil: 85,7 dari sampel yang tenascin-c positif mengalami resolusi inflamasi yang normal. 66,67 dari sampel yang tenascin-c negatif mengalami resolusi inflamasi yang tertunda. Kesimpulan: Ada korelasi antara ekspresi tenascin-c dan resolusi inflamasi pada perlukaan pasca sirkumsisi.

Background Circumcision is a common invasive surgical procedure to remove the preputial skin. It involves the wound healing process, consisting of 3 phases inflammation, tissue rebuilding, and tissue remodeling. Tenascin c is an extracellular matrix protein highly expressed during tissue injury, renewal, and regeneration. Tenascin c expressions are found at sites of inflammation, it especially peaks at the incision wound edges. This research aims to identify a correlation between tenascin c expressions at the circumcision incision area and the inflammation resolution of circumcision wound healing. Method Preputial skin samples were obtained from a mass circumcision event, afterwards they underwent histotechniques which includes hematoxylin eosin staining and immunohistochemistry specific for tenascin C. Data was also obtained from a follow up interview conducted 14 days after the surgical procedure. The interview was confirmed with physical observation to determine state of inflammation resolution. Results 85,7 of tenascin c positive samples exhibits normal inflammation resolution. 66,67 of tenascin c negative samples exhibit delayed inflammation resolution. Conclusion There is a correlation between tenascin c expression and inflammation resolution in post circumcision wound healing.

ABSTRACT
Sirkumsisi telah dianggap sebagai salah satu prosedur bedah tertua dan paling sering dilakukan. Meskipun telah banyak teknik-teknik sirkumsisi yang telah diciptakan, tidak ada mufakat dalam penentuan metode sirkumsisi yang terbaik dalam praktik, terutama dalam ketentuan perbaikan jaringan kulit. Tenascin-C TNC adalah glikoprotein ekstraselular yang terbentuk selama embriogenesis dan meningkat sewaktu penyembuhan luka, terutama dalam fase resolusi. Dalam penelitian ini, penulis menganalisa penyembuhan luka akibat sirkumsisi dengan dorsal-slit method dan kauter laser melalui ekspresi Tenascin-c. Kulit khatan dari 20 partisipan laki-laki 5-12 tahun dikumpulkan dan diwarnai dengan pewarna hematoxylin-eosin untuk menentukan area insisi. Ekspresi tenascin-c diamati dengan imunohistokimia: rasio area dengan TNC positif dan batas pinggiran insisi. Hal ini diikuti dengan daftar pertanyaan pasca-operasi beserta foto-foto dari partisipan untuk menentukan status penyembuhan luka. Grup konvensional memperlihatkan ekspresi TNC yang lebih besar 57.28 47.56 dibanding grup kauterisasi 25.36 16.44 p=0.07 . Rata-rata ekspresi TNC pada subyek dengan penyembuhan luka yang normal 42.15 40.87 sedikit lebih tinggi daripada rata-rata pada subyek dengan penyembuhan luka yang tertunda 38.83 33.40 p=0.872 . Tidak ada korelasi yang signifikan antara ekspresi tenascin-c dengan proses penyembuhan luka. Dari data yang terkumpul dapat dilihat bahwa dorsal-slit dan kauterisasi method, kedua-duanya membuahkan perbaikan jaringan kulit yang normal.

ABSTRACT
Circumcision has been noted as one of the oldest and most common surgical procedure. Even though, various techniques have been developed, there is no consensus on best practice method for circumcision in terms of skin tissue repair. Tenascin c TNC is an extracellular glycoprotein expressed during embryogenesis and markedly increased in wound healing, especially in resolution phase. In this study, the author analyzed the outcome of skin tissue repair dorsal slit and laser cauterization through expression of tenascin c. Prepuces from 20 male participants 5 12 years old were collected and stained using hematoxylin eosin staining to determine incisional area. Tenascin C expression was determined by immunohistochemistry with ratio of TNC positive area and incisional margin. Follow up investigation was done using post operative questionnaire and photographs to determine the status of wound healing. The conventional group showed greater TNC expression 57.28 47.56 than cauterization group 25.36 16.44 p 0.07 . The mean expression of TNC in normal wound healing subjects 42.15 40.87 is slightly more than the mean of delayed wound healing subjects 38.83 33.40 p 0.872 . There is no significant correlation between tenascin c expression and wound healing process. The number of subjects with normal healing after cauterization or conventional techniques is almost identical. The data presented here suggested that both dorsal slit and cauterization methods resulted in normal skin tissue repair.

Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 84-86 The progressiveness of malignant tumors is influenced by various complex factors. One of the important factor is Tenascin-C (Tn-C) protein, which can interact with fibronectin as an anti adhesive of anti modulation protein. Tenascin-C is an extra cellular matrix glyco protein (EMG) which can be found in the oral tissue also as an up regulator. They can be associated with EMG, and strongly influenced promotion of the stromal cell as cell growth, migration, differentiation, angiogenesis, and apoptosis in cancer. Alternative splicing of fibronectin-like type III (FN lll) repeats of Tn-C generates a number of splice variants, and influences tumor progressiveness. The conclusion of Tn-C role in tumor progressiveness depends on the molecular weight and alternative splicing of FN lll. ;Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 84-86;Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 84-86
