Latar Belakang: Perubahan genetik pada p53 menyebabkan imortalisasi dan kecenderungan sel bertransformasi menjadi neoplasma. Imortalisasi ini berhubungan dengan pemeliharaan panjang telomer oleh telomerase. hTERT adalah komponen kunci telomerase yang aktivitasnya ditekan oleh p53. Tujuan: Menganalisis profil protein hTERT pada sel galur KSSRM HSC-3 dan HSC-4 serta jaringan mukosa mulut normal. Metode: Profil protein hTERT dianalisis menggunakan teknik SDS-PAGE dan Gel Doc, Quantity One. Hasil: Protein hTERT diekspresikan oleh sel galur KSSRM mulut tipe HSC 3 dan HSC 4 serta 2 dari 17 sampel protein jaringan mukosa mulut normal. Simpulan: Protein hTERT yang diekspresikan oleh sel galur KSSRM berhubungan dengan kondisi mutan p53. Adanya ekspresi protein hTERT pada jaringan mukosa mulut normal diperkirakan karena adanya sel keratinosit dan infiltrasi sel hematopoietik.
Backround: Genetic alteration on p53 allows cellular immortalization and predisposes cells to neoplastic transformation. This immortalization is related to telomere length maintenance by telomerase. hTERT is a key component of telomerase, which activity is suppressed by p53. Objectives: To analyze the hTERT protein profile in HSC-3 and HSC-4 OSCC cell lines and normal human oral mucosa tissue. Methods: SDS-PAGE and Gel Doc, Quantity One were used for analyzing hTERT protein profile. Results: hTERT protein expressed in HSC-3 and HSC-4 OSCC cell lines and 2/17 protein samples of normal human oral mucosal tissues. Conclusion: hTERT protein that was expressed by OSCC cell lines is related to their status of mutant p53. The existing of hTERT protein on normal human oral mucosas tissue may be caused by keratinocyte cells and infiltrated hemapoietic cells.

Stomatitis Aphtous Rekuren (SAR) merupakan kondisi inflamasi kronis yang terjadi pada mukosa mulut yang ditandai dengan terbentuknya ulser. Patch mukoadhesif dapat ditujukan untuk melindungi ulser dari lingkungan mulut dan meningkatkan efektivitas terapi RAS dengan memperpanjang durasi perlekatan. Kurkumin merupakan senyawa yang memiliki aktivitas antiinflamasi sedangkan brazilin memiliki aktivitas antimikroba yang keduanya dapat digunakan untuk terapi RAS. Oleh sebab itu, tujuan penelitian ini adalah membuat dan mengevaluasi patch mukoadhesif dari ekstrak kayu secang dan kurkumin untuk terapi RAS. Patch mukoadhesif dibuat dengan teknik solvent casting dengan menggunakan polikarbofil dan etil selulosa sebagai polimer. Bahan padat dilarutkan dengan etanol lalu ditambahkan plasticizer kemudian dituang ke dalam cawan petri. Patch dibuat dengan 3 formulasi kurkumin-ekstrak kayu secang yang berbeda, yaitu 1:1 (F1), 3:1 (F2), dan 1:3 (F3). Patch yang terbentuk dievaluasi sifat fisiko-mekanik serta profil pelepasannya. Patch memiliki bobot yang seragam dengan ketebalan kurang dari 0,1 mm. Nilai kekuatan tarik sekitar 10,0 N/cm2, kekuatan mukoadhesif berkisar 6,7 sampai 7,5 N/cm2 dan mampu melekat hingga 2 jam. Dalam waktu 2 jam, brazilin telah terdisolusi sebanyak 100,58 % (F1) hingga 104,75% (F3) sedangkan kurkumin terdisolusi sebanyak 97,15% (F3) hingga 101,64% (F1). Secara keseluruhan, patch dapat dibuat dan memiliki karakteristik fisiko-mekanik dan profil pelepasan obat yang baik. ......Recurrent Aphtous Stomatitis (RAS) is a chronic inflammatory disease of the oral mucosa characterized by the formation of ulcers. Mucoadhesive patch is designed to protect the ulcers from the oral environment and increase the effectiveness of RAS therapy by prolonging the duration of attachment. Curcumin is compound that have antiinflammatory activity while brazilin have antimicrobial activity, both of which can be used for RAS therapy.

ABSTRAK
Efek samping gastroduodenal sering terjadi pada pengunaan aspirin jangka panjang, bahkan pada dosis yang sangat rendah (10 mg/hari). Saat ini angka kejadian kerusakan mukosa gastroduodenal akibat penggunaan aspirin dosis rendah jangka panjang di Indonesia belum diketahui. Tujuan: Mengetahui prevalensi dan gambaran endoskopi kerusakan mukosa gastroduodenal pada pengguna aspirin dosis rendah jangka panjang pada pasien yang berobat di RSCM, serta faktor-faktor yang mempengaruhi. Metode: Penelitian ini menggunakan desain potong lintang pada pasien poliklinik dan ruang perawatan RSCM usia ≥ 18 tahun yang mengkonsumsi aspirin dosis rendah (75-325 mg) lebih dari 28 hari. Didapatkan 95 subjek penelitian melalui metode konsekutif dalam periode Desember 2015 ? April 2016. Temuan endoskopi berupa erosi mukosa dan ulkus peptikum dimasukkan ke dalam kelompok kerusakan mukosa. Hasil: Kerusakan mukosa gastroduodenal ditemukan pada pada 49 subjek (51,6% (95% IK 41,6-61,7%)), dengan gambaran erosi mukosa pada 38 subjek (40% (95% IK 30,2-49,9%)) dan ulkus peptikum pada 11 subjek (11,6% (95% IK 5,2-18,0%)). Hanya 44,9% pasien dengan kerusakan mukosa gastroduodenal memiliki keluhan dispepsia. Kombinasi antitrombotik meningkatkan risiko terjadinya kerusakan mukosa (OR 3,3 (95% IK 1,3 ? 8,5)). Sedangkan penggunaan obat golongan proton pump inhibitors (PPI) menurunkan risiko (OR 0,2 (95% IK 0,04 ? 0,60)). Kesimpulan: Kerusakan mukosa gastroduodenal terjadi pada lebih dari separuh pasien yang menggunakan aspirin dosis rendah jangka panjang. Kombinasi aintitrombotik meningkatkan risiko kerusakan mukosa. Sedangkan penggunaan PPI efektif dalam menurunkan risiko tersebut.
ABSTRACT
Background: Long-term aspirin therapy can induces gastroduodenal mucosal injury, even in a very low dose (10 mg daily). The frequency of gastroduodenal injuries among long-term low-dose aspirin users in Indonesia is currently unknown.Aim: To determine the gastroduodenal mucosal injury prevalence, endoscopic findings, and influencing factors among long-term low-dose aspirin users in RSCM. Methods: This study was a cross-sectional study conducted in Cipto Mangunkusumo Hospital, Jakarta. Subjects were ≥ 18 years old patients that have been using low-dose aspirin (75-325 mg) for at least the preceding 28 days. Ninety five subjects were recruited consecutively in the period of December 2015 ? April 2016. Endoscopic findings such as erosions and ulcers were assessed as mucosal injuries. Results: Mucosal injury was found in 49 subjects [51.6% (95% CI 41.6?61.7%)]; mucosal erosion in 38 subjects [40% (95% CI 30.2?49.9%)] and ulcers in 11 subjects [11.6% (95% CI 5.2?18.0%)]. Only 44.9% patients with mucosal injury had dyspepsia symptoms. Double antiplatelet therapy increases the risk of mucosal injury [OR 3.3 (95% CI 1.3?8.5)]. However, proton pump inhibitor (PPI) decreases the risk [OR 0,2 (95% IK 0,04 ? 0,60)]. Conclusions: Gastroduodenal mucosal injury was found in more than half of long-term low-dose aspirin users. Double antiplatelet therapy increases the risk of mucosal injury, while PPI effectively reduced the risk.;

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

Abstrak :
Oral mucous inflammation is common in our community. Therefore we need an anti-inflammatory medicine with affordable price, relative low adverse effects, and easily obtained in our environment. Sweet fennel is a plant that widely used in our community as a decorating plant, food flavouring and herbal medicine for various diseases. The affectivity for fennel has not been clinically examined. Therefore we are interested in finding our the affectivity of sweet fennel as an alternative anti-inflammatory. The aim of this research is to examine and compare reaction of both crushed and distilled fennel fruit on inflamed oral mucosa caused by hydrogen peroxide 10%. 14 rats were used and divided into 4 groups, and controls (6 rats). They received hydrogen peroxide 10% applications on vestibulum mucosa for there days to make the inflammation. After that they received crushed and distilled fennel. There days later they were killed and the vestibulum mucosa was excised for microscopic slides. The results show that the crushed the redness of oral mucosa. The conclusion is fennel could reduce an inflammation and there is no difference of healing either by crushed or distilled fennel.

One of the traditional plants that has been broadly known as the healthand healing plants is Aloe vera. It is often use to treat burns, wounds, abrasions, skin disease, alopecia, and irritation. It is further more used as a hair washed to promote hair growth and as general cosmetics to improve the complexion and to smoothen the skin. The aim of the study was to examine and compare the reaction of fresh Aloe vera and distillate Aloe vera on the inflammed oral mucosa caused by hydrogen peroxide 10%. 14 rats were used in this research and divided into 4 groups; fresh Aloe vera group (4rats), distillate Aloe vera group (4 rats), control group I (3 rats), and control group II (3 rats). All rats in each group received 9x10 minutes application of hydrogen peroxide 10% on their vestibulum mucosa, for 3 days, except rats in control group I received application of aquadest. On the 4th day, all rats in each group received 9x5 minutes with their own group's material for 3 days. The histological examination was done by scoring the density of lymphocytes in the inflammation area. Statistical result shows that there are differences of oral mucosa reactions between distillate Aloe group and fresh Aloe group. Fresh Aloe group shows the decrease of lymphocytes cell higher than distillate Aloe group. Based on this research, it can be concluded that application with fresh Aloe vera can cure oral mucosa inflammation cause by hydrogen peroxide 10% than application with distillate Aloe vera.

Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 12-16 A case of chronic bullous type mucocutaneus disease involving oral mucosa was reported from a 56 years old man with never healed oral ulcers and wound on the perianal skin for three years. There were also red and black sports on the limb and back skin and a lesion on nail. Painful oral lesion consisted of mucous erosion, desquamative gingivitis, and sloughing area on palate and tongue. The patient is diabetic. The first perianal skin diagnosis was granulomatous candidiasis with differential diagnosis pemphigus vegetans and acuminatum condiloma. However, the histopathologic examination did not support those diagnosis. After several histopathologic examinations, the latest perianal skin diagnosis was lichen planus with differential diagnosis granulomatous vasculitis, bowenoid papulosis and pyoderma gangrenosum. Other skin diagnosis was erythema multiforme. Oral diagnosis was mucous membrane pemphigoid with differential diagnosis lichen planus, Behcet's syndrome and erythema multiforme oral histopathologic examination showed a sub-epithelial blister, which supported mucous membrane pemphigoid. A lip balm, prednisone 5 mg oral rinse and multivitamins were given but oral improvement started after blood sugar level controlled. Conclusion: lt is not yet known whether skin and oral mucous lesions are from the same disease or not.

Abstrak :
Recurrent Aphthous Ulceration (RAU) is a type of local inflammation of the oral mucosa with symptomatic soft tissue damage. The prevalence of RAU is about 17-67 %. Dominant factors causing this disease are understood, but there are predicted internal and external factors that cause related immune disorders. RAU is initiated by mucous proteins which continuously stimulate a physiological response required for a pathophysiological reaction. The aim of this study was to characterize specific anomaly proteins in oral mucosa as causing the initiation of RAU. Samples of mucosal proteins from 30 RAU patients were analyzed with sodium dodexylsulphate polyacrylamid gelelectrophorese (SDS-PAGE) and visualized with silver stain (AgNO3) showing proteins with a range of molecular weight 27 - 180 kDa. Western blotting using a polyclonal antibody specific to RAU showed that the specific proteins of RAU have molecular weights of 23, 27, 65, 70 and 87 kDa. The finding of so many proteins appears to be a new phenomenon, suggesting that the initiation of RAU is possibly due to a continuous induction of internal and external reactions by several mucosal proteins, that become anomaly proteins of high reactivity and antigenicity. This situation can cause overreaction on the oral mucosa with specific symptoms that are known as a RAU.
