"Latar Belakang: Ameloblastoma merupakan tumor yang berasal dari jaringan epitel odontogenik pembentuk gigi. Umumnya ameloblastoma jinak, tapi bersifat agresif secara lokal dengan tingkat rekurensi yang tinggi. MMP-2 merupakan salah satu yang paling berkaitan dengan invasi ameloblastoma. Matrix metalloproteinase-2 (MMP-2) merupakan enzim proteolitik yang diproduksi dalam sel-sel di seluruh tubuh dan menjadi bagian dari matriks ekstraselular, yang merupakan rangkaian rumit protein dan molekul lain yang terbentuk diruang antara sel-sel. Tujuan: Mengetahui sifat invasi lokal ameloblastoma dari sisi molekular. Metode Penelitian: 30 sampel ameloblastoma terdiri dari 8 sampel tipe pleksiform, 5 sampel tipe folikuler, dan 17 sampel tipe campuran. Sampel dipulas secara immunohistokimia dengan antibodi MMP-2. Hasil: Terdapat perbedaan ekpresi MMP-2 dari sel epitel pada berbagai tipe ameloblastoma. Terdapat perbedaan ekspresi MMP-2 dari sel fibroblast pada berbagai macam tipe ameloblastoma. Tipe campuran memiliki tingkat invasif yang paling tinggi dari ketiga tipe ameloblastoma dan memiliki sifat yang lebih infiltratif. Kesimpulan :Terdapat perbedaan ekspresi immunohistokimia matriks metalloproteinase (MMP-2) terhadap sel epitel dan fibroblast ameloblastoma tipe folikular, pleksiform, dan campuran.

Background: Ameloblastoma is a tumor which originate from odontogenic epithelial tissue. Mostly ameloblastoma is benign, but can be locally aggressive with high recurrence level. MMP-2 is one that connected with ameloblastoma invasion. Matrix metalloproteinase-2 (MMP-2) is proteolitic enzim that produce in body cells and become part of extracellular matrix. Objective: Understanding ameloblastoma local invasion from molecular side. Methods: 30 samples plexiform type ameloblastoma (n = 8), 5 samples folicullar type, and 17 samples mixed type.

"Penelitian ini bertujuan untuk menguji sitotoksisitas tiga merk dagang eugenol pada fibroblast gingiva manusia, untuk mengetahui eugenol yang paling tidak toksik terhadap jaringan bila dipakai untuk pengobatan gigi. Dari ketiga merk dagang eugenol, Kimia Farina (El), Dentsply (E2), dan Cavex (E3) dibuat campuran medium-eugenol masing masing menjadi 0,031%, 0,062%, 0,125%, 0,25%, 0,5%, 1%, 2%, dan 4%. Dilakukan kultur sel primer fibroblast gingiva manusia, dan setelah sel konfluen kemudian dipajan dengan masing-masing konsentrasi medium-eugenol selama 24 jam. Penghitungan jumlah sel yang masih hidup dilakukan dengan uji metode assay MTT. Hasil uji assay MTT menunjukkan bahwa E3 dengan konsentrasi 0,062% mengakibatkan jumlah sel vital sangat menurun, sementara pada El dan E2 penurunan jumlah sel tidak tampak. Sel menjadi tidak tumbuh pada konsentrasi El dan E2 0,25%, dan hal yang sama terjadi pada E3 dengan konsentrasi yang lebih rendah 0,125%. Kesimpulan: El dan E2 merupakan eugenol yang kurang toksik dibandingkan dengan E3."

"Bacterial lipopolysaccharide (LPS) is impacted in the etiology of inflammatory periodontal disease. Aside from immunopathologic reactions which may be involved in the pathogenesis of the disease, the possibility exist that direct cytotoxic effect on cultured human gingival fibroblasts may be equally destructive. The expression of P53 protein can be one of markers to examine the state of impaired DNA. The purpose of this study was to investigate the effect of LPS toward expression of P53 protein on cultured human gingival fibroblasts. Cultured human gingival fibroblasts were exposed to LPS in concentrations of 50 and 200 ug/ml and untreated medium for a period of 24 and 48 hours. Cells were harvested and prepared for immunohistochemical evaluation. After exposure for 24 and 48 hours, the fraction of P53-positive cells was 81.7% in case of 50 ug/ml LPS, and 88.8% in case of 200 ug/ml LPS. After exposure for 48 hours, the fraction of P53-positive cells was 32.2% in case of 50 ug/ml LPS, and 21.1% in case of 200 ug/ml LPS. None of untreated group showed p53-positive cells. Up-regulation of p53 protein during the initial logarithmic phase of growth may be a consequence of on-going DNA damage."

Histological preparation was stained with hematoxyline-eosin (HE) and was continuously examined by counting the numbers of PMN leukocytes and fibroblasts as indicators of wound healing on days 3, 6, and 13 of treatment.The study showed lower numbers of PMN leukocytes in subjects treated with the extract of Jatropha multifidaas compared to the other groups. The numbers of fibroblasts were significantly higher on days 6 and 13 of treatment. In conclusion, the treatment of injuries with methanol extract of leaves from Jatropha multifida provided better results compared to the other groups in our study."

"ABSTRAKIn vivo apoptosis of fibroblast pulp cells by ionizing radiation from radiotherapy of the head and neck area has not yet been demonstrated. The study aimed to show in vivo the effect of a single dose of ionizing radiation on apoptosis of fibroblast pulp cells. The sample group consisted of 24 healthy male Wistar rats that were 3-4 months old and 150- 200 g in weight. The rats were divided into 4 groups of 6 rats that were subjected to Cobalt 60 radiation to the head at the levels of 0, 100, 200 or 400 rad. The rats were sacrificed 24 hours after radiation exposure, and the lower incivus were taken for histopatological processing. Apoptosis was detected by using the TUNEL Assay method. The apoptotic fibroblast pulp cells were counted under light microscope by multiple observers using the blind test approach. The fraction of apoptotic cells was counted as mean of labial and palatal sides of the teeth below odontogenic and free-cell zone. The data were statistically analyzed using one-way anova. The results showed the percentage of apoptotic of fibroblast pulp cells was 6.4, 23.7, 34.5 and 17.8% after 0, 100, 200 and 400 rad doses, respectively. There were significant differences in the apoptotic percentages between the four groups (p<0.05). In conclusion, the highest fraction of apoptotic fibroblast pulp cells was found after a single 200 rad dose, and this fraction decreased after a single dose of 400 rad."

"Wound healing is a biological response that occurs following a trauma or pathologic condition of the oral mucosa. Wounds require proper management so they may heal faster and without complication. The number of fibroblast cells seen in the oral mucosa is a strong indicator of wound healing. In the remodelling phase of wound healing, fibroblast cell proliferation decreases as collagen fibres are synthesized. Noni leaf (Morinda citrifolia L.), a part of the noni plant, is traditionally used to heal soft tissue wounds in Indonesia. The leaves have potential chemical compounds that may be useful in the wound repair process. Objective: This paper aims to examine the effect of ethanol based pastes of the Indonesian noni leaf on oral mucosa wound healing by investigating visual wound closure and fibroblast cell counts in Wistar rats. Methods: Rats were divided into 2 control groups and 4 treatment groups. The pastes were formulated in concentrations of 2.5%, 5%, 10%, and 20% and were applied onto wounds of the oral mucosa of the rats. One control group was given no medication and the other control group had an ethanol gel with a concentration of 10% noni leaf extract applied to their intraoral wounds. Result: Result revealed that all groups treated with noni leaf paste experienced better wound closure (p<0.05) when compared to the control groups. Fibroblast cell counts showed little significance amongst all groups (p=0.143), however fibroblast cell counts of groups treated with noni leaf paste, of all concentrations, were lower than both control groups. Conclusion: These results suggest that topical application of noni leaf paste promotes better oral mucosa wound healing than gel formulas but shows no significant difference in the amounts of fibroblasts during the remodelling phase."

"Fibroblast growth factors (FGFs) have been recognized primarily as autocrine/paracrine factors that regulate embryonic development and organogenesis. However, recent studies have revealed that some FGFs function as endocrine factors and regulate various metabolic processes in adulthood. Such FGFs, collectively called endocrine FGFs, are comprised of three members (FGF15/19, FGF21, and FGF23: FGF15 is the mouse ortholog of human FGF19). These endocrine FGFs share a common structural feature that enables the endocrine mode of action at the expense of the affinity to FGF receptors. To restore the affinity to FGF receptors in their target organs, the endocrine FGFs have designated the Klotho family of transmembrane proteins as obligate co-receptors. By expressing Klothos in a tissue-specific manner, this unique co-receptor system also enables the endocrine FGFs to specify their target organs among many tissues that express FGF receptors."
